2574 - A tooth elevator? This site - http://carmichael.lib.virginia.edu/st=
ory/tools.html
- has a double elevator, page down near the bottom, under "Dental
Tools 1800s".

"The dental instrument on the top is a double elevator. It was used to
apply hard pressure to the tooth. This forced the tooth against one of
the sides of the socket causing the bone around the tooth to compress.
After repeating this step many times, the socket became larger,
loosening the tooth. The next step was to use the bottom instrument, a
toothkey, so named because of its similarity to an eighteenth-century
door key. The claw attached around the patient=EF=BF=BDs tooth allowing for

2572

This is a booby-trap, or trip-wire firearm, and is attached to a solid
object, such as a door frame or tree trunk. A wire or string is
solidly affixed on one end, and the other is tied to the ring. When
someone walks into the wire, the weapon discharges.

The wire could also be attached to a door, and when the door is
opened, the firearm shoots whoever is entering the room.

2569, don't have any real knowledge. I'm guessing that modern doctors would
say "quack" about this.
2570, with that much metal, I'd be wondering if it's for whacking or beating
something. A bit much for massage. Maybe a nut cracker?
2571, some kind of specialized valve turning wrench. Beyond that, not sure.
2572, Polish Suicide Pistol. Hold the body of the device, pull the ring. I'm
getting the sense that it's a small, easy to conceal firearm. But, I've
never seen such a design.
2573, hair shears?
2574, no clue.

Some of those treatments look as painful as the disease. Or, more so. I
wonder if the doctors killed more patients than the disease?

Rob, on that last item...

I used to keep goats. That is almost identical to a "dis-budding" iron we
used to de-horn young kids. In fact, had I not been dawdling, I'd have
suggested that earlier. It's so close to what we used, it could be the
same tool.

2572 I've never seen this, but...
It is a semi-automatic palm gun.
The magazine is the area behind the cover with the 3 holes.
The trigger is the ring.
The sear is in the bottom center of the first picture.
The striker is between the two long springs at the top.
The two long springs and the linkage at the center are the extractor.

2573 From the artsy shape of the handles, I'd say this is a surgical
tool rather than a kitchen scissors.

2569 A medical Quack device to provide quadrature ("rotating") electric
field. I guess it contains a coil rotated by the knob and a pair of
orthogonal output coils.

2571 Obviously a tool to turn a valve in a hard to reach position.
I'll be interested to hear what specific situation caused the production
of this tool rather than fixing the original accessibility problem.

Yes, palm gun is the answer that I was looking for.

I was guessing that it was a power supply for some type of equipment but
quack device sounds like a good possibility.

Someone left a comment on the web site concerning the wooden piece from two
weeks ago, the one with the slot in the middle and the metal part on the
top, they said it looks like a balero, which is a cup and ball type toy from
Mexico except in this case the wooden object is caught on a stick. I'm
looking to get a few more opinions on this theory so if you have any
thoughts pro or con on this idea please post them.

2569: This looks very much like something from the Museum of
Questionable Medical Devices. It's missing the wires and
electrodes that should be connected to the binding posts2573
arrayed around the dial. There might be a hidden battery, or
two of the posts may have been battery terminals. It could
be anything from a galvanometer to a phlogiston meter.

2570: At first it looks like a diamond-shaped pestle, but the
third image makes the head look like a scoop of some kind.
The only reason I can think of for a diamond-shaped pestle
would be to do stuff that has round slippery granules, so you
could corner the little barstids!

Looks to me like that is a good answer (Balero). It might be a slightly
different version. Per the Wiki page it has several names/varieties
depending on the country of origin:

http://en.wikipedia.org/wiki/Balero

In the current set 443, item #2569 may be a Cautery Transformer. I
uploaded the relevant page from an old catalog I have locally saved.

Here's a video of an expert.
http://www.youtube.com/watch?v=ZWZ7o-8H_-0

The large balero he uses looks like 8 ounces. The mystery item is 40,
which seems too big for flipping on a string. The slit would be
useless, and the spacers would come out.

Balero appeared in Mexico in the 16th Century. King Henry III of France
played it publicly. He died in 1589. It was obscure in France for a
century after that.

Today it is popular under various names in Mexico, Argentina,
Brazil,Chile, Colombia, Ecuador, Venezuela, and Spain. In Spain, it's
boliche, the same term they use for tenpins. Like a bowling pin, a
balero barrel seems to be cut on a lathe. It would surprise me if the
New World had tools to cut a balero on a lathe.

That leads me to speculate. In 1500, Spanish royal cartographer Juan de
la Cosa made a map of the New World that was so closely guarded that
historians didn't know about it until the 19th Century. Its accuracy is
amazing. If their maps were closely guarded secrets, so was the
technology. Like the United States government as of 1973, Spain may
have directed mapmakers to use the sun to determine north.

In the 14th Century, bowling was so popular in Europe that the kings of
England and France outlawed it. Asturias, Spain, has a bowling museum
with exhibits dating back to 1495. Spanish surveyors may have found
that the balance, diameter, and bulge of bowling pins made them ideal to
sight sunups and sundowns. Best of all, a spy would assume the
cartographer simply liked to bowl.

In the New World, what better way to win hearts and minds than to
distribute souvenir bowling pins, symbols of Spanish technology in
manufacturing and surveying? If bowling pins had hollow bottoms to
raise the center of mass, the natives could play balero. That could
have led Spain to export millions of balero barrels.

California was Mexican until 1846. With a slit to sight the sun at the
right moment, 40 ounces to resist the breeze, and bone markers, this may
have been the state of the art for a Mexican mapmaker. Those white
disks would show up on almost any ground. The surveyor would probably
mark them with flags.

In 1846, the Americans took over. Their best surveyors had solar
compasses, and everybody forgot what the antique was for.

That's my story and I'm sticking to it... for now.

Thanks. I'll never forget the day the judge's son invited me home after
school and showed me a similar box. It had belonged to his grandfather,
a doctor in practice about 1900.

The box contained a 1.5V carbon-zinc doorbell battery. I was sure it
must be flat after all those years, but we hooked it up. We fiddled
until I did a backward somersault across the living room into a couch.

As I tumbled, I thought he must have punched me incredibly hard. When I
came to a stop, I saw he wasn't aware I was gone.

If it was a cautery transformer, the battery didn't belong with it. We
may have hooked the battery to the low side. I may have grabbed the
terminals on the high side. If he broke the battery connection, that
could have caused a pulse on my side, like ignition points.

William Ansyl Phillips was known for making electrical resistance

problems with the ears, nose, and throat.

Aha! It takes 6 terminals to attenuate headphones with a pair of

From what I've seen on researching disbudding irons, they are used in a
similar manner as cautery irons and could probably be used interchangeably.
The one on my site is from a doctors medical kit so I would lean towards it
being a cautery iron though I didn't see one like it on the web nor did I
see a disbudding iron like it but I did see some of each tool that were
close. Thanks for the info on the dehorning tool.

Sounds reasonable, I'll ask the owner if there were any headphones with it
when he got it, in case it came in a box of stuff that he didn't realize
might have been related.

In 1858, "Scientific American" and the New York Tribune carried articles
about using electricity for dental anesthesia. In the 1859 Edinburgh
Medical Journal, J. Smith, MD, wrote about it. The patient would hold
one conductor and the other would be attached to the forceps. Smith
concluded that it didn't block pain but could have a placebo effect.

Forty years later, most dental offices had AC. In the mouth, perhaps
1ma at 10vac could provide a tingle. Perhaps the dentist used a drug
for extractions and added the light bulb and tingle for placebo effect.

Or possibly the tingle was to hide the needle stick?
Or maybe a speed controller for a drill prior to the air powered high
speed ones? Different speeds depending on the bit being used ?

It looks unsafe to hook up 110VAC to exposed terminals, but at least
they and the lamp terminals have plastic caps. The front terminals,
which the operator could easily touch when reaching for the knob, have
no plastic. That led me to believe the voltage was too low to feel with
the hand and the resistance too high for a metal tool to draw much of an
arc.

That led me to think it wasn't a motor control. I agree that it might
have been for needle pain.

You got me to look up dental drills. Electricity made it possible to
reach 3,000 rpm in 1914. Nowadays, it's often 400,000 for drilling and
40,000 for other tasks. I believe the electric ones have run on belts,
but now there are dremel motors that let a dentist change speeds in the
middle of a job.

2569. Easy that's a shock therapy unit designed to raise the hair on
Bill's head.

2573 Since they were made in Italy , they must be the GOD FATHERS finger
remover.

Posting from Rec.crafts.metalworking as always.

2569) O.K. Two heavy duty ground terminals (binding posts (lower
corners, connected to the front plate.

Two heavier insulated terminals at the top.

Two lighter insulated terminals at the left hand side.

Pointer knob with 13 visible marked positions, and possibly
another under the tag hanging from right-most top binding post.

Pointer between two markings, suggesting that it is not a
detented switch -- unless the setscrew for the knob was loosened
and retightened off position.

Markings cover about the 270 degree arc which is common for
potentiometers (variable resistors), but the knob suggests that
it might be a Variac (or some other brand name) variable
autotransformer inside. If a Variac, it will be quite heavy,
though it could also have a separate power transformer in it
which is not obvious from the views we are shown.

Lacking any other markings, and any other views of the box (e.g.
the back or bottom might have a power cord, I'll have to assume
that whatever power it uses comes in between one of the ground
binding posts and one of the heavier top ones. The output,
then, would come out one or both of the left side binding posts,
either referenced to the ground binding posts, or to each other.

It could be for delivering an adjustable shock voltage to a
patient. Such were once believed to be beneficial.

It could be for adjusting signals to a pair of headphones, to
test hearing sensitivity.

Lots of other possibilities.

2570) Perhaps for splitting slate, or some other form of stone work?

2571) A ratcheting wrench for operating something like a valve whose
stem faces away. I don't see all of the ratcheting mechanism
(which looks like one which would be found on an old woodworking
drill brace.)

2572) Looks like a firearm which is enabled by a key -- perhaps
another form of jailer's key gun. If the key or the gun are
grabbed individually, they do not arm the inmates, but the
jailer, possessing both, is armed. Looks to be at least
multi-shot, and perhaps self-loading as well.

2573) Poultry shears. The notch is for cutting through bones.

2574) Perhaps not actually medical, but rather a seal used with
sealing wax to indicate that a bill has been paid.

Now to post this and see what others have suggested.

Enjoy,
DoN.
