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.

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 !

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

and is commonly used to cut steel exhaust pipes using a split chisel.

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.

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.

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'm not so sure about the crimper guess---don't know I've ever seen an

the stand plays--doesn't seem at all necessary, therefore Occam says...

752. Roman Numeral 4 on a clock.

Michael Terrell:

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.

My text in this article is in the public domain.

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.

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 . . . .

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.

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.

There's no such thing as a free lunch, but certain accounting practices can
result in a fully-depreciated one.

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. ;-)

Sir Benjamin Middlethwaite

According to R.H. :
This week's set has just been posted:

http://puzzlephotos.blogspot.com/

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.
