1. Both Pneumatic
2. Both operate on the repeated explosive release of supplied compressed air.
3. Both have 'cutting blade-type' tip
4. Both held by a human and used to cut into things
Seems like an excellent paraphrase to use to explain an air chisel to someone
who knows what a jackhammer is.
If you can't see that Leon, you don't understand one or other tool, or the
English language.
753 is a photographic contact printing frame. When larger negs or
plates were used there was no need to enlarge, so the negs were
sandwiched with photographic paper (in "contact") and exposed to the
light from the bulbs in the base. It could also be called a proofer.
I'm so happy he's branching into photographic stuff... I have a hope of
getting a few right !

750. It looks like a screwdriver whose split handle can be folded down
to increase torque.
751. No idea - but that shouldn't prevent a wild assed guess, right?
Might be a sand rake for small Japanese Zen gardens.
752. Part of a clock dial with Roman numerals.
753. Light table for photography. It looks like some of the socket
bases are replacements.
754. Bottle cap crimper.
755. Pneumatic chisel.

No, it's a pneumatic connector. You're right in general, however, it's
a "pneumatic hand-held jackhammer" to paraphrase...

I have been around air chisels for at least as long and if you WOULD

call it a jackhammer, I used the term to give the other poster an idea
what it does...
paraphrase ( ) n. A restatement in another form or other words...

I _DID_ do that (and said I was doing it, too!) Now, you can quibble
over whether it was a good paraphrase, but there should have been no
confusion whatsoever that I called the tool in question itself a
jackhammer but you were simply looking for an excuse to slam somebody.
The Romans were polluted by the use of the Egyptian Cubit. That is why.
The Egyptians tended to group verticle lines, but not always.
The inverted U was 10 a verticle line to the left is a 1 or one.
So there were lots of 1's or verticle lines before another inverted U.
The current (one under inspection) segment would have n number of verticle lines
dividing that segment (1/28th) of a cubit.
I find it a commoners grade of math rather than that of a learnered person.
OBTW - I have a 48" tall clock that a friend bought us (wife and I) and it has
some 'funky' numbers on it. And it would have been quicker, easier and fewer parts
if done in pure Roman but was in low level Roman.

IIII is also a Roman numeral -- in ancient Roman usage, it was the
usual notation. Similarly, 9 was VIIII. The preference for IV and
IX came later.
If you actually look at clockfaces with Roman numerals, you will
find that they do commonly use IIII for 4, even though 9 is IX and
not VIIII. This is considered to look more attractive due to the
visual balance with the respective numbers on the opposite side:
III opposite IX, IIII opposite VIII.
I just did a Google Images search on the keywords clock, roman, and
numerals. Here were the first 5 results that showed actual clocks
(as opposed to a drawing of a clockface or that sort of thing) with
Roman numerals. All five use IIII.

Jack hammer? Absolutely known as an Air Chisel in the automotive business

Wrong. The negative plate is placed on the glass, then photo-paper is
placed on the negative. The light is turned on for the appropriate
length of time and the photo-paper (not the negative) is emersed in
the developer.

I think the handle is split. So it can be opened out on both sides,
giving excellent torque.

753. The lamps and cover suggest that something goes on the glass plate and
is lit by the lamps. Perhaps something goes on the glass plate under the
cover and then the lamps shine onto it, something where part of the item
has been coated somehow with light sensitive chemicals. I would say its for
making printed circuit boards but it looks too old for that. Something to
do with making plates for a printing press of some kind perhaps?
754. Looks like a clamp for some kind of scientific glassware perhaps (with
the base resting on the metal extensions and the neck or body being held by
the jaws of the clamp.
755. Some kind of mechanical, electric or power type chisel? Its hard to
tell but there might have been an electric cable that goes into the handle
at the bottom that powers it and then the trigger is pressed to make the
blade/bar move in and out.

Leon, you are absolutely right. Some people, for
whatever reason, just never get the point of being
specific. There is a much relations ship of knife
to a sword as there is a chisel to a jack hammer.
Just heard on the TV, one news stations said they
found a blasting cap in the luggage, another said
they found a stick of dynamite. Exactly what I
would expect from reporters who usually have
little science or technical knowledge in any
field. I think you could (should) expect a
little higher standard of comments in a technical
newsgroup.

No, not always. In fact, the antique E N Welch steeple clock sitting
on my mantel has IIII for the four o-clock position. And my
grandfather, who was a clockmaker and repairman, had many clocks like
that. The reason is esthetics; the IIII is across from a VIII and
makes the dial look more balanced than an IV would . . . .

The same comparison could be made between an 18 wheeler and a go cart.
I suppose if you stretch your imagination and don't want or need an accurate
comparison a jack hammer is similar to an air chisel, except that an air
chisel can usually be pointed in any direction to accurately cut sheet
metal, pipe, peen objects, cut small nuts and bolts and so on. I only see a
jack hammer as a demolition tool.

Would a wood handle be good for a tool repeatedly exposed to water under
pressure? Bronze will corrode in salt water.
I think was designed long ago for working around magnets, and the pivot
is to use it in tight places. I wonder if it was for working on
generators with permanent magnets.

Absolutely correct but some clocks, including one I have use th 4 I's. Both
versions are used.
753 is definitely a contact printer. It looks like it may have been cobbled
up out of existing components. The top cover/door has a hinge, which allows
the user to close it part way and observe the alignment of the paper with
the negative. The stand looks very well made, but not quite right for its
use. Maybe converted from a typewriter desk. The inside should be painted
white. The bulbs should all be the same.
754 looks like a tool for loosening the screw tops on bottles, but why the
bent rod hook-hanger looking things? My suggestion is it is for gently
holding the neck on a bottle of cheap wine, so the tipsy drinker has less
chance of dropping it. ;-)

I have been around air chisels since the early 70's and have never heard of
them referred to as jack hammers. Correctly named they are hammers or air
hammers. Jack hammers are typically held by 2 hands and are much larger.
Perhaps it's a regional thing.
Most of them have been answered correctly this week:
750. Triple lever screwdriver, the handles fold down for better torque.
751. Not sure what this tool is for, see the answer page for a list a
guesses.
752. Number 4 on a clock
753. Kodak Crown printer

You are digging a deeper hole. Most cameras don't
magnify they make an image smaller than the real
object.
There is not lens in the object described,
therefore it can't be an enlarger.
Actually the paper is immersed in developer not
the light. (which is what your sentence said).
It would be easier if you just gave up! or better,
admit that you were wrong. May insight be your gift.

Your first point seemed on the mark. There's no point in being
intentionally obtuse pointing out a misplaced modifier. I'm relatively
certain most people understood the meaning.

O.K. Posting from rec.crafts.metalworking as usual.
750) A screwdriver on which you can swing the handle to the
side, thus allowing a lot more torque.
751) For spreading mortar or cement.
752) The curvature of the tops and bottoms of the Roman numeral
suggest that it is part of a dial like on a clockface. And
(unless the image has been rotated) the presence of a '4' at the
bottom suggests perhaps a counter from zero to seven for the
days of the week -- so a secondary dial on a complex clock.
753) For contact printing large negatives. The tiny red bulb
allows you to align things without exposing the paper.
The spring fingers are designed to spread the clamp-down force
over the whole of the negative and paper.
754) The gripper is about right for a bottle cap similar to that
found on a ketchup bottle, however the support fingers below
don't look right for that. Perhaps for unscrewing a sampling
bottle from under something?
755) Compressed-air driven chisel.
Now to see what others have said, and then crash.
Enjoy,
DoN.

To paraphrase, is to redescribe a text or passage in another form or other
words.
You did not do that. You mentioned a much larger tool/piece of equipment,
the jackhammer.
Ok, In my neck of the woods if you mention a Jackhammer a vision of a much
larger tool that is often used to break up concrete comes to mind.
If I said, hand me that hand held pile driver, would you think hammer?

How about, "Jill Hammer"? ;-)

In Houston, the "on the scene reporters" like to describe the ankle deep
water running down the curb as treacherous. I guess it is treacherous if
you are hit by lightning while standing in the water.

I agree about the wood handle scales. I'm not entirely convinced about it
being bronze. I dropped the image in PS and adjusted for the white paper. It
could be bronze, or it could be patina. However, nobody has commented yet on
the flip-open handle, which would give a 12" t-bar... plenty of torque.
Because "R.H." <[email protected]> could, he/she/it opin'd:

OK, I'll give it a shot this time:
750: a screwdriver with a variable-angle handle.
751: ??
752: The Roman numeral 4 from a antique clock (I have one just like it
on the fireplace mantel). I don't know why they sometimes used IIII
and sometimes used IV, but they did,
753: Looks like an ironing table for shirts, but what are the light
bulbs for??
754: Specialized pliers, but haven't a clue for what.
755: An air chisel; I have one quit a bit like it in my Man Garage
This is fun! THANX!!

I'm sure that 755 is an air chisel with an extra long bit.
I am totally lost on all other pictures this time. Nice job RH.

Good idea, I'll just change the numbering, no big deal as long as I can
remember to do it four days from now.
