the first power tool

i was doing some drilling with the drill press today and appreciated the fact
that i just applied downward force to drill a big hole with a forstner bit and the
motor did the rest

compared to an attempt with a brace and bit recently i am very aware that
a drill press is good

but it got me thinking about the succession of power tools in a historical
perspective

i figure the saw was the first one to get some power behind it with those
big lumber mills saws

but what was next
i think power drills must have been the next one

power in this sense is not animal powered

I was thinking - and I think John McCoy (and perhaps another poster) -
of a different reservoir. It's not as if you were just standing there
pouring water back and forth into the same two glasses.

If you view the water as fuel to run the generator (turbines) or ???,
then by using the electricity generated which is in excess of that
currently needed (low demand period at night?) to pump fuel (water) to
that other reservoir which may not be filling by itself as quickly you
now have an expanded source of "fuel" with which to run a different
generator turbine or divert the water for irrigation purposes. Somewhat
analogous, I think, to a storage battery. Electric "fuel" is stored in
a cell, water "fuel" is stored in the reservoir.

I'm sorry if the answer is still too complicated for you to understand. I
tried to explain in the simplest way that I could when you asked what
seemed to be a simple question. Perhaps you did not understand the
question you asked. It's not really complicated.

Reread your question several times and my answer the same amount of
times. That might help.

And as I have stated, I am being anal. This can be read to be
understood almost any way you want it to.
It very well could be the real deal but as you have point out maybe this
was not the first.
I'm not trying to be difficult, it's that there are other equally
compelling sources that mention other people and times.

How would you suppose the 10% is stored, batteries?

That is pretty cool, not photovoltaic. I missed the salt part.
I could see how rain during the night might hamper but there is probably
not much problem with that considering where it is located.

So just to clarify, you asked,
So if she did not invent the circular saw then what was the purpose of
the circular blade design?

Consider this. A saw, any saw, a circular saw, will not cut with out a
blade. A blade is not a saw. A saw can be a saw with out a blade. So
if you were thinking that a circular blade is a circular saw, I can see
how you would be confused on the whole issue.

She came up with a better design blade, some one else came up with a way
to operate the blade, The machine/tool that operates that circular
blade would be called a saw, and or circular saw.

Ackshooley, the old two man crosscut saw I used cut on both strokes.
The teeth were symmetrical in both directions.

She invented the "blade design". But regardless what does location have
to do with whether it was a man or woman that came up with the idea? ;~)

I'm sure the machine to run the blade came a touch later. But for sure
there was no circular saw before there was a circular blade. ;~)

Again, it goes to comprehension, I guess. Tabitha Babbit was born in
1784 and the first patent mentioned for circular saws was issued 1777.
If she was able to invent the circular saw 7 years before she was born,
why didn't she invent the multi-tool and SawStop while she was at it?

"There is an oft-quoted assertion that the circular saw blade was
invented in 1813 by Shaker Sister Tabitha Babbitt (1784–1854). This is
most often cited by Shaker “historians”, aficionados-of or workers-in
that design idiom, or by other parties who are simply parroting the
aforementioned mentioned sources. However, there is nothing in the
historical record to document this claim, and considering the existence
of the Miller patent some thirty-six years before, and various
authoritative and credible sources on the history of woodworking
technology describing systems in use more than a century before that,
this claim is unsubstantiated and without basis in fact."

Your band saw comment is equally telling. The bandsaw was invented in
1808 by William Newberry, but it never really went anywhere until the
French developed a metallic blade that could withstand the constant
flexing ca 1860.

Maybe the circular blade you attribute to Samuel Miller's patent was a
50' coil of chain saw blade.


Ignorance can be cured, stupid is forever.

Why would it need gears? Just turn the shaft with a belt.

It's exactly analogous to a storage battery. The voltage on the
battery corresponds to the height of the reservoir (both represent
potential energy) and the flow of water to the current (kinetic
energy). In both systems there are losses converting potential energy
to kinetic energy and verse visa.

Interesting, but that's a very narrow definition of "power tool". Steam
locomotives are tools and the first of those went into service around
1804. And then there was John Henry and the steam drill . . .

I don't know when the first powered tool went into service, but the
Romans had a sawmill running around 300 AD.

I don't know why you put "woman" in quotes. Are you suggesting she was
a man in drag or something? However whether she invented it is
debatable--there are earlier references to circular saws, including some
that mention them in passing on patent applications, suggesting that
they were either well established at the time of the application or not
deemed sufficiently interesting to be worth patenting on their own.

So if she did not invent the circular saw then what was the purpose of
the circular blade design? Were the Shakers playing high-stakes Frisbee
or something?

I'm sorry, but you're babbling incoherently. You've been doing enough
of that lately to make me worry for your health. Please get a checkup
and be sure to inform the physician that others tell you that you babble

Yep. Perhaps the ox-drawn plow was the first "power tool" by that
definition, around 3000 BC.

Tried to help but it appears reading comprehension may not be your
strong suit. What is? A contrary attitude or something else as others
have suggested?

"that receives the saws, which are a circular figure," written in the
stilted language (or legalese) of the times seems to suggest to everyone
else a circular saw. What do YOU think it means? An early version of
the Stryker saw with a half moon blade (but it could be called circular)
that cuts by vibrating against solid resistance?

Try clicking on a few of these links and read them through. If you plan
on being obstinate, the least you could do is do a bit of investigation
on your own and read what's out there rather than just shaking your head
"No!"

Yes water power.

The stored water could have gotten there by a few different ways, rain,
run off from a river, etc.

It does not really matter how the stored energy gets there, the energy
that directly powers the tool is what drives the tool.

Jumping in this very late in the thread,
Just came back from Alaska 2 weeks ago. I thought they had a great use
of water. Alaska is a rain forest in many areas (not all).
They would run a pipe down from the high lakes only about 10-12" pipes
and be able to power many homes from the force of the water in that
small pipe. I imagine had a very good impeller design too. Very efficient.

Yeah,,, but were you around in the early 1800's when the circular blade
was invented to replace the single stroke in the saw mill? LOL

Wow grade school responses.... I have mentioned this to another here,

Exactly my point, now. There are multiple references to this claim.
And the 1600's Dutch wind mills.
Pick the one you want to believe. It really does not matter which you
believe, history is not going to change and discrepancies can be found
with all.

I dunno. It seems unusual but...

I don't think they have that much control over the hydroelectric
generation. They build a damn, water level rises and they harness the
flow to generate needed power. If their capacity exceeds their needs
and the needs of other areas or power companies tied into their
production, what can they do? Surely they can cut out the generators
and stop production and just let the water bypass the turbines. They
can't stop the water flow or it will cause flooding.

I liken the Colorado "solution" to a storage battery. They are charging
up a power source capable of providing, perhaps, additional
hydroelectric capacity during peak demand or, alternatively (as someone
mentioned), provide water for irrigation. Simple case (or maybe not so
simple logistically) of making the most of what they have?

I think the trick here is going to be defining what's a tool
more than what's power, but certainly you're right that
water powered mills for grinding grains have been around for
a very long time.

As another contender, I'll offer the spring-pole lathe,
altho that's arguably animal (human) powered.

A common claim, but not true. The Royal Navy had circular saws
in the Portsmouth dockyards in the 1790s and contemporary texts
don't describe them as a new invention. The Portsmouth dockyard
had numerous tools powered by steam engine and belting by 1802,
some of which have been preserved.

The actual inventor of the circular saw seems to be lost to time.

I'd agree. Steam powered saw mills I've seen from the 1890's
(sample size of 2) have two blades, a large one for ripping,
and a smaller one mounted on a swinging arm crosswise to the
carriage, to cut boards to length.

The swinging arm allowed the blade to move, which otherwise
would be difficult with a belt drive.

I'd guess someone figured that arrangement out very soon after
they figured out how to spin the ripping blade.

Well, with apologies to Unquestionably Confused, it seems
evident that circular saws existed long before Ms Babbitt.
Ergo, since the blade must have existed before the saw by
your own admission, Ms Babbitt did not invent either the
saw or the blade.

OP specifically excluded tools using animal power (which
presumably also includes human power).

There's a bit of a fuzzyness there, tho, if you consider
stored power. If an animal compresses a spring, or carries
water to an elevated tank, and that is then later used to
power a tool is it still animal powered?

Spot on, but wrong. Tabitha Babbitt did not invent the
circular saw, and did not invent the circular saw blade.
It's a good story, but there's plenty of reference to
circular saws long before Babbitt and the Shakers.

Well now, Leon you have moved from being anal to being a full fledged
a**hole. You cannot be that dense. Even the "citations" you offer
indicate that Tabitha was not the first, just that she appears to have
come upon the principle/design independently.

They do the reverse thing in Colorado - at night when electric
demand is low, they use the excess electricity to pump water
up to a lake way up in the mountains, and in the daytime when
they need extra capacity, they let it flow back down thru
generators.

I'd agree with you that water powered (and horse powered)
lathes came before steam powered (and all of them well before
electric lathes).

It's probably worth noting, tho, that demand for lathes to
make anything other that light stuff like chair spindles was
pretty minimal prior to the invention of the steam engine
and consequent Industrial Age, so water powered lathes would
not have been very common.

Pretty sure water predates wind as a power source for milling
grain and stuff (the Greeks and Romans had water mills), but
purely as a power source you'd have to count sails on boats,
I think, and those go back to the ancient Egyptians if not
even further back.

It's generally the case with steam plants (coal fired, nuclear,
whatever) that they can't be run efficiently at lower power
outputs. So where possible, it makes sense to size the steam
plant at, say 90% of maximum demand, run the steam plant at
100% capacity all the time, and save 10% at night so you can
provide 110% capacity when demand is at maximum.

(to Unquestionably's point, yes, hydro is easily controlled.
Unlike a steam plant where there's typically only one turbine,
hydro plants usually have multiple turbines that can be cut
in and out, and running them at less than full capacity
isn't as inefficient as it is with a steam turbine).

Um, if you read upthread a bit, you'd see it's stored by
pumping water uphill, and then letting it flow back down
thru hydroelectric generators when it's needed.

Batteries, while theoretically possible, in practice are
a lot more complicated than using water. They're used in
a few places on a small scale. Other small scale storage
mechanisms include compressed air, and electrolizing water
into hydrogen and oxygen (later recombined in a fuel cell).

I'd guess pumped water makes up 99% of the electric utility
energy storage capacity.

One of the problems with solar energy is that places which
are good for large-scale solar tend to be flat, meaning
that pumped water storage (for night time use) isn't
possible. There's a fortune to be made for whoever figures
out a good alternative.

I think I wasn't clear there.

Suspose the peak demand is 100MW - daytime, AC running in
the summer, heat in the winter, businesses have all their
machines and computers and whatnot running. And at night the
demand is only 70MW, because people are sleeping, not using
much electric equipment.

Now, suspose we design a powerplant with maximum capacity of
90MW. We're 10MW short of what's needed for peak demand,
but we have 20MW extra at night. So we use some of that 20MW
to pump water uphill at night, and in the daytime we let it
run back thru a 10MW hydro generator. Thus we get the extra
10MW we need at peak demand times.

This all makes sense because:

a) powerplants are expensive, and the savings from building
a 90MW plant instead of a 100MW plant pretty much covers
building the pumping plant.

b) running a 90MW powerplant at 70MW is inefficient, and will
consume almost as much fuel as running it at 90MW, so the
power used for pumping is almost free.

Ah, I see the problem.

The site I'm familiar with, Cabin Creek in Colorado, is typical.
There is one lake/reservoir above Georgetown, and another one
about 800 vertical feet further up the mountain. They pump
water from the lower one to the upper at night, and let it flow
from the upper to the lower (thru the generator turbine) in
the daytime.

The upper reservoir does get a little water from snowmelt,
but that's lagniappe. Mostly it's the same water being pumped
up and down every day.

I agree, but the OP's question was rather vague and the followup answers
wandered all over the place as well.

Just to throw some more sh*t in the game, the first time a human hooked
an animal to any device that performed some sort of work on behalf of
said human could probably be said to be a power tool driven by other
than the user's hand power.

When were the Pyramids built? Inca temples? Surely if a system of
ropes and pulley or levers were employed they would be classed as tools.
Add one animal to the equation and we're talking power tool in the
context of the OP's question<g>

Just saying, there are references of others before the date of the
patent too. Several years ago my father brought my the claim of the
Quaker woman and that is the only one I have heard about until this
thread. I'm just saying what makes a copy paste reference to a British
Patent more authentic than references to an earlier time, perhaps long
before patents even existed.
Taylor's Mill going back to 1762 mentions circular saws but no patent
was perused.
Then there is mention of 1600's Ducth wind mills that drove saw blades
instead of millstones.

Circular saw was invented by a woman and used water power. 1813.

I would love to see a drawing to back this up. I am closer to believing
this but " through the small wheel goes a square bar of iron, that
receives the saws, which are a circular figure, does not quite convince
me. I know I am being anal about the description, but saws are not
blades. And there is not mention of blades that I saw. A drawing would
be what I would need to see.


There is a lot of readily available historic documentation that backs
up Babbit.

That seems a reasonable statement. I seem to remember reading
somewhere that her first version was powered by a treadle from
a (yarn) spinning wheel.

I note that, by Electric Comet's original query, that means it
was not a power tool by his definition.

I think what he's describing there is a sawmill, not a table
saw. The "chariot" is what we would today call the carriage
(for carrying the log); the screw annexed to the end is to
move the log sideways, to set the thickness of the resulting
board.

The fondness of old-time authors for mile-long sentences,
with a thousand commas, makes it hard to follow their exact
meaning.

Not trying to be a help, just looking for a better explanation of who

I'm sorry if me not seeing this the same way as others is causing

Babbit invented the table saw - or portable circular saw used by
wordworkers making furniture. The large circularsaw used in sawmills
was "invented " in the late 1700s in europe - and ganged circular saws
were in use well before 1800 to cut several boards at once.

I think I can resolve this for you guys. My wife bought a parakeet last

enough affect that it drew my attention.

I just heard a big "THUD" a minute ago--I thought What could he have
possibly dropped??? Checking around, A large Redtailed Hawk flew into my
window--no doubt after my new new circular saw! He flew off after a
few minutes, so no harm no foul, I guess. I could see the parakeet on
his perch through the window when I was mowing, but it didn't occur to
me that anyone/anything else would take an interest.. Put a naked light
blue bird in your window and the voyeurs come out...lol!

Actually, our Mr. Miller describes a moving (XY axes_ table saw in his
patent outlining the manner in which it was used...

"Those saws being in motion, the matter or substance they are to cut is
brought forward as follows:— The horizontal shaft, as mentioned before,
hath a small wheel on it, with a groove to receive a rope; the rope is
continued to a smaller, that hath a pinion to it, connected to a
straight bar under the chariot, which hath teeth to match the pinion;
the chariot moves in a groove likewise on a centre; it hath two motions.
one to advance forward, and the other sideways, which is performed by a
screw annexed to the end of the chariot. This screw is turned by hand to
direct the pieces against the saws, agreeable to any line wanted to be cut."

Now, granted, he being a sailmaker (and other &c &c :) ) undoubtedly his
version was more for beams and all for boatmaking and hence quite a lot
larger than the typical furniture/cabinet maker's needs, it clearly was
a tablesaw for the purpose of other than sawing logs lengthwise into lumber.

I don't have any problem whatsoever following the meaning...I don't
doubt it was intended _primarily_ to cut beams but it had the
flexibility to "direct the pieces against the saw, agreeable to _any_
line wanted to be cut." All it takes is orientation of the workpiece.

Maybe I am just jealous that in the first 9 or 10 weeks of its life it
has learned to keep "perfect" hours--something I have not done very well
for over 50 years now. God works in mysterious ways...

Our Budgie jumped and hit his head tonight, and birds have thin bones.
He was buried in sight of the area he surveyed through his window, along
with his favorite ladder. Although he was only with my wife and I for a
short time, he enriched our lives.

But unless I am missing something here, It does not matter how much
water is in the reservoir/lake because whatever water is there to begin
with is enough to operate the power plant at capacity.

Unless the water goes to a different reservoir that does not naturally
refill itself to power the smaller generator.


And FWIW I am picturing Lake Mead as the reservoir.

Yeah I saw that.... but, If you run at 100% capacity/output, having 10%
more water/fuel is not going to increase capacity. You still have the
bottle neck of 100% capacity. Maybe I am mixing two different
explanations here.
And, it seems that if capacity is only 90 percent of demand, taping
into 100% capacity to pump water back the the reservoir that it would be
counter productive. Certainly there is a loss of capacity pumping the
water back up stream than it produces.

Understood but batteries supplement/add to output. Recycling water does
not add to on demand capacity, unless the lake is about to go dry.

Not arguing with you here, just kicking thing around.

I don't see circular blade any where, if this is the patent for a
circular blade. Seems more a patent for saw mill machinery.

They can't all be true, And for that matter a record can be false and or
incorrect. Not saying that this one is but only one of the claims would
be correct in being the first to invent. And like you said, research
would have to be done but even that would only be as accurate as the
available documentation.

And I don't claim to be an expert, historian or amateur historian.
It is just that there are multiple claims over the last 400 years and
the one with the patent is not the earliest.

The point to all of the references that I have made is that
the most common searches point out the woman as the inventor. There are
plenty of other references that dispute this. I don't argue this point.
The references I added give "multiple" possible inventors of the
circular blade which include her and the guy that has the British patent.

The same could be said of your interpretation. The 250 year old

See, the description leaves much to be desired as far as interpretation.

You say not a saw mill, but it says,

The shaft of this mill stands vertical,

Take a look at http://circularsaw1813.weebly.com/ -

It is a "circular saw" not a "saw mill"

Again, you're selectively quoting, apparently just for the sake of
arguing...that phrase in context is

"The machine that gives the power, a horizontal windmill. The shaft of
this mill stands vertical, ..." which is clearly describing the power
source and "this mill" is the windmill of the preceding sentence. It
goes on to say "the upright shaft being in motion, communicates its
power to a horizontal shaft" which is then the one which drives the saw
_blade_.

Reading for meaning it's quite easy to visualize the concept and one
could build a working version from this description alone.

I was simply pointing out the recognition of a woman's contribution.

I was thinking about the (grain) mill, but you're probably right. The

Hydro plants, whether pumped storage or natural reservoirs, have
the chief characteristic that the power generation can be adjusted
rapidly by adjusting the flow through the penstocks.

For this reason, hydro plants are used as 'peakers', i.e. plants that
are brought on-line to supply generation during peak usage periods
and to quickly adjust to variable generation supplies (solar, wind) while the
baseload plants run at optimal efficiency.

Pumped storage will use electricity during off-prime periods when
the cost is less to pump water into the reservoir, and during prime
periods will use that water to supply peak generation needs.

Some pumped storage alternates on a daily basis between pumping and
generation, while others (e.g. San Luis Reservoir) stores water in
the wet months for power use during the dry summer months (with
the advantage that the released water is subsequently used for
irrigation in the central valley or for delivery to the LA basin
via the California Aquaduct).

In other cases (trinity->whiskeytown->shasta->keswick) the same water
may be used four or five times for generation before it reaches the ocean
or central valley.

There were many woodworking shops located near rivers, streams. Most
all the equipment was run by belts driven by a water wheel.

I would feel confident in saying that those shops existed before
electricity was introduced.


Googled, and found this. Look at the second picture.

I suspect you are right about the first power tools being those used in
sawmills. However I suspect that the reciprocating saw was used before
the circular saw. A reciprocation saw could be connected to a water
wheel and operated with a cam. The circular saw would need a complicated
set of gears to make spin

Before the Circular saw was used probably the most common type of saw
was what was called a Pit saw. It was a cross cut saw, and was used on
a on a platform pit arrangement. One person on the platform that other
person in the pit and the log between them.

On this line of thought another power tool may have been the water
powered hammer mill.

Well, that's pretty limiting definition in terms of historical
precedence but water was certainly around quite early as a power source.

The Chinese and Romans had waterwheel-powered trip mills for as early as
1st century AD and some say even earlier.

The Roman Hierapolis sawmill cut stone block dating back to 3rc century
AD incorporated a crank and connecting rod for reciprocating motion; the
first known instance although undoubtedly somebody had the idea even
earlier it's the first documented location of an operational facility.
As for specific woodworking I don't know what was the first we have
record of but I'm sure it's quite old.

Per the article there is a question of whether a woman invented the saw

While the saw could be fixed on the water wheel Depending on the ratio
between the diameter of the water wheel and the saw diameter, it would
turn relatively slow. The gears would be used to increase the speed of
the saw blade.

Both circular saw and the reciprocating saw (Pit saw) were rip saws.

I forget which water mill it is in Indiana, (We visited most) but that
reciprocating saw was used for ripping logs in to useable planks.

I do not know when the circular saw was first used for cross grain
cutting. ie in a construction type of environment.

I don't know but expect at the same time or very shortly after the were
adapted to cut to length...folks didn't generally wait around back then
for somebody else to come up with a modification; _somebody_ at a mill
somewhere did it long before the electric motor and the Skilsaw like
portable tool.

Not only does it "suggest" it, it says it specifically and without
equivocation. I was unaware of this patent previously; that's pretty
kewl and thanks quoting it but as I was reading it I was struck with
precisely the thought outlined in the link to it that notes that it "...
is worded in such a way as to imply that the circular blades were
commonplace by that time."

That implication would be my impression as well as that there were in
all likelihood various forms and incarnations of saws with circular
blades all over particularly western Europe/England far earlier than
this that individuals had cobbled up on their own. I'd venture the very
first circular cutting blade probably preceded even this by quite a long
time and there may well have been something tried clear back in the
Roman times or earlier we just haven't come across. Anybody checked all
of Archimdes' sketches and/or da Vinci?

We tend to forget there were a lot of _very_ clever folk way back
when...in some ways far more so than currently where the "average joe"
has become so dependent upon technology available from vendors simply
for the asking...

Absolute nonsense. Where would the square iron bar onto which the saws

This isn't "anal", it's move to the realm of just arguing for the sake
of arguing. It can't be reasonably read to mean anything other than
what it means; it's quite clearly written albeit in language of 250 yr
ago or so, not in today's uni-syllable style. You're deliberately
_mis_interpreting it.

Which, specifically, do you think more (or even equally) "compelling"
that predate this and what (other than obstinacy) prevents acceptance of
this at face value for what it clearly says?

Common searches are simply that--just because they exist doesn't mean
they're of any real value. In this case since our Ms. Babbitt wasn't
born until _after_ the date of the patent, that pretty conclusively
demonstrates she wasn't first irrespective of what they may say.

Also I'll note that you disputed (and selectively and creatively made
what appear to be deliberate efforts to obfuscate) the meaning of the
patent as being what it clearly states it is simply, it appears, to keep
an argument going.

Lastly, rather than as the "devil's advocate" role of providing a
constructive interpretation in lieu of the obvious one related
specifically to how, instead, it could reasonably be interpreted to have
another meaning, you simply said "no" in other places than the
aforementioned wrong interpretation.

If you were to care don that mantle and to make that detailed
interpretation substantiated by references that indicate whatever terms
you think in doubt are indeed misunderstood by us and do have some other
than the meaning ascribed, I'd at least consider it (although I don't
think there's any case whatever that can be made that it says anything
other than the obvious).

Don't know that _anybody_ in the entire claimed this was _the_ first;
simply the first _known_ patent; who knows, there may be earlier of
those as well yet to be discovered.

As for claims of whether it's bogus or not; if you want to refute it,
it'll need more than "just saying".

That's a far cry from any previous posting claim, sorry.

But if you're going to claim there's something bogus, it needs more than
just shouting to refute it...actual research and documentation is the
only way to correct the record (which is what reputable historians and
even collectors and amateurs at least attempt to do).

that is water powered

just like using the force of methane gas emanating from a cow to
turn the blades of a windmill would still be wind powered
you could even ignite and it would still be wind powered unless the cow
goes too

now in the south pacific they use solar power during the day because
there is plenty of sun but at night they had a problem so they use
solar power pumps to pump water to elevation and at night they rely
on water power to watch their favorite shows

but really it is gravity at work but we still call it water power

Well, the data _can_ all be true (and most of what was posted here was
as far as the facts of _what_ and dates; it's the other claims of trying
to establish "firstest" that are applied external of actual fact that
are suspect. But, of course, when it's pretty clear that the person
some are claiming to hold the honor wasn't yet born when it's also
pretty clear that there were such already in existence is pretty easy to
refute logically. Once it's on the internet, however, it has the

No need to get uppity. I stated I was being anal and the key words that
I was looking for. Did you see circular blade?

This could easily be describing a band saw which has a circular blade
which is circular too.

A big pulley on the shaft of the wheel and a small pully on the shaft
of the saw, with a flat belt, can run the saw much faster than the
wheel with no gears, and higher efficiency.

I suspect Sir Flinders Petrie would take issue with your assessment of
minimal demand for lathes prior to the steam engine. ;-)

A simple Google search...



British patent, No. 1152.

To SAMUEL MILLER, of Southampton,

Sail maker, &c., &c.

NOW KNOW YE, that, in compliance with the said proviso, I, the said
Samuel Miller, do hereby declare that my said invention, of an entirely
new machine for the more expeditiously sawing all kinds of wood, stone,
and ivory, is described in the manner following (that is to say):—

The machine that gives the power, a horizontal windmill. The shaft of
this mill stands vertical, with four levers fixed to it at right angles
with the shaft, to which levers are fixed the sails. These sails when in
motion are one-half of their time horizontal, the other vertical. The
upright shaft being in motion, communicates its power to a horizontal
shaft. This shaft hath a large wheel to it, round which goes a rope or
chain, which is continued to a smaller; through the small wheel goes a
square bar of iron, that receives the saws, which are a circular figure.
Those saws being in motion, the matter or substance they are to cut is
brought forward as follows:— The horizontal shaft, as mentioned before,
hath a small wheel on it, with a groove to receive a rope; the rope is
continued to a smaller, that hath a pinion to it, connected to a
straight bar under the chariot, which hath teeth to match the pinion;
the chariot moves in a groove likewise on a centre; it hath two motions.
one to advance forward, and the other sideways, which is performed by a
screw annexed to the end of the chariot. This screw is turned by hand to
direct the pieces against the saws, agreeable to any line wanted to be cut.

In witness whereof, I, the said Samuel Miller, have hereunto set my hand
and seal, this Fifth day of August, One thousand seven hundred and
seventy-seven.

[Signed] “SAMUEL MILLER.” (L.S.)

Yes, a "woman" invented the circular saw blade to solve the ills of the
straight blade saw.

While power tool can be loosely used for most any thing that puts out
power. I would be willing to guess that the term power tool was not
used until after electricity was introduced. The electrical companies
sell power, power tool.

The need was for a more efficient and durable design. The dual stroke
of the straight blades only cut in one direction. The return stroke was
a wasted motion as far as cutting was concerned. The circular blade
never has to reverse direction to continue the cycle.

I'm sure you could envision how spinning the circular blade would not be
a stretch of the imagination.

No all of this is with the assumption that we both agree that a circular
saw spins a circular blade.

I'm finding it difficult, so far, to pin down the first tool driven by
other than hand, but here's something relevant to what we commonly call
power tools:

In 1895, 16 years after Thomas Edison invented the incandescent electric
lamp, the German engineering company C&E Fein combined the power of an
electric motor with a manual drill to develop the world's very first
power tool. (It was about 19 years later that Mr. Black and Mr. Decker
teamed up to improve on this invention by making it lighter, more
powerful and capable of being operated by a single DIYer<g>)

(maybe that's why they are so expensive... A company that old, if it
didn't properly fund its pension debt could have quite a bill coming due
120 years down the pike.<g>)

This circular argument needs to stop! ;)
