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.
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.
Keep the whole world singing . . . .

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 !
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.
I have been around air chisels for at least as long and if you WOULD
READ and understand what you read you would clearly see that I didn't
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...
Now, are you satisfied yet???
To paraphrase, is to redescribe a text or passage in another form or other
You did not do that. You mentioned a much larger tool/piece of equipment,
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?
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.
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.
750 - Looks kind of like a split handle Dzus fastener tool.
751 - Scraper tool?
752 - Numeral 3?
753 - Glass plate contact print table?
754 - Cap crimp tool
755 - Chicago Pneumatic 715K Heavy Duty air hammer (made in Utica NY)
with long chisel bit.
You are digging a deeper hole. Most cameras don't
magnify they make an image smaller than the real
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.
