2426 Inline ferrite bead on a cable to control electromagnetic emissions.

[Alexander Thesoso]

2425 Guess: A tool for marking or engraving radial marks on a
watchface. A changeable gear (top of the drawing, near Fig. 1) sets the
angular spacing, with the pawls (S) doing the indexing. A marking or
engraving tool (K) marks the workpiece with radial lines, activated by
(L). Internal ratchet/pawl (D,H) makes different length lines
periodically.

2427 Another guess: A portable press, but why the spring?... Because
whatever is being pressed has a variable, unpredictable thickness. I'll
guess something like leather. So this is to install grommets in leather
harnesses.

2430 Some sort of optical comparator. The user looks into the eyepiece
at the top, sees a split image of somethings on the round stages.
Adjust the knobs 'till something in the images match. Use? I'll guess
to compare mineral grain sizes.

Or stained bacterial/specimen slides. The mirrors below the specimen
"plate" would allow light to reflect/shine from below, onto/through
the specimen... a similar feature on old microscopes (I have one).

2430 Looks like an antique instrument to measure the comparative optical
density of chemical solutions to determine concentration. If that is what
this is, a standard solution is placed on one side in a glass cylinder, and
the unkown on the other, and the optical path lengths are adjusted until the
transmission appears equal. The concentration is calculated from the ratio
of path lengths. It could also be used to measure turbity of fine particle
suspensions as in water quality.

2428 looks like a siphon assembly for pulling liquid through the small pipe
and spray it out the end of the larger pipe when air or another fluid flows
through the larger pipe

Posting from Rec.crafts.metalworking as always.

2425) I could tell that the hooked arms were designed to engage a
gear as a form of escapement even before I scrolled down to the
patent drawing.

And the drawing shows in addition a coarser escapement between
the plates.

however -- its actual function is a different matter. I would
expect a flat wind-up spring in there somewhere, but it is not
present (though some other things which are missing from the
photographed item are present.)

It would appear that there is some kind of scribing tool which
draws a line on the external gear.

It would also appear that there is a second bulbous handle to
slide on the pivot controlling the external escapement -- or the
original one can be slid off the primary shaft and not the
secondary one.

At a guess, it might be a tool for holding a blank and filing
gear teeth onto it, but I would need more drawings, a complete
object to examine, or the full descriptive text in the patent to
figure it out for sure.

2426) *Way* too little shown to be able to form a guess.

Are there two shafts, or just one passing through the central
object.

Is the central object rigidly fixed to the shaft(s)? Could it
be a simple free turning handle for thumb and finger gripping on
a small crank?

Could at least one shaft be removed, and an old toy gun paper
cap be placed in there, and the other smartly slapped onto it to
detonate the cap? (If so, I would expect more vents from the
inside to the outside.

Could it be a free-sliding weight on a shaft, used to impart
momentum to the shaft and whatever it is attached to?

2427) Not sure what it is from, but it is some kind of spring loaded
assembly where the arms can be pulled a fairly long distance as
the spring compresses in comparison to the length of the spring.

It *might* have some kind of latch connected to the button in
the center, so you could cock the arms apart, and then hit the
button to power something sudden.

2428) Hard to be sure what it is made of. Part of it appears to be
copper, based on the Verdi-gris on it, but the right hand arm
appears to be wood, with a piece chipped out.

Some kind of scientific equipment from long ago perhaps.

Or -- part of something like a Hookah?

2429) Nasty looking thing.

Before I saw the close-up, I was thinking something like a
"Chinese finger trap" used for pulling cables through conduit or
the like.

But the close-up looks like something related to barbed wire,
but designed to be pulled through a gap to act as a saw.

2430) Perhaps a scientific device for measuring relative humidity, if
there are thermometers in the protected glass tubes. Each would
be connected to the metal plate sticking out in front, one would
be dry, and the other contain a fabric soaked in water, and both
would be subjected to airflow, so the relative cooling from
evaporation of the water would allow calculation of the relative
humidity.

The knobs appear to be for adjusting the height of a relative
reference line on each thermometer.

Not sure what locks into the base, however.

Two alternative possibilities:

a) Used for measuring differential pressure, with the tubes
partially filled with mercury.

b) Bubble levels. Not sure why two in parallel, but it
could be that.

Now to post and see what others have suggested.

Not really fair to put up this number of serious puzzlers and
then go out of town.

Enjoy,
DoN.

Good answer, this is correct.

The entire item is made of metal, I haven't yet found an answer for it.

Yes, it's made from barbed wire but it's not used in the manner of a saw. I
wouldn't describe it as a tool, although I suppose an arguement could be
made for it to fit into that category.

Probably not but sometimes it can't be helped. ;-) Three of this set have
been answered so far, I won't be able to post the rest of the answers until
Friday as usual.

Yes -- but the photo made me think of it as steel -- hot oil
dipped to surface treat it for rust. A pity that it was not a gray cord
instead of a black one. I might have spotted it then. (Or if the wire
had shown some bend instead of appearing straight like steel rod. :-)

Picking nits, 'to control *conducted* electromagnetic
interference' is more accurate. These ferrites do
almost nothing to control 'radiated' electromagnetic emissions.

I think this one is an arm exerciser but I haven't been able to prove it or
rule out that it's some type of tool.

Forgot to mention earlier that the colorimeter was tagged as a microscope
with a price of $135, I figured that if it was really a microscope it would
be worth more than that, but was almost certain it was misidentified. I
found the answer and decided not to buy it, and when I went back a few days
later to take some better photos it had been purchased by someone else.

Still not sure about two of them this week, answers for the other four can

2428. It looks like lamp adapters/finials used on electric lamps. If the
threads are 1/4-27 that would support this. Gas lamp piping also used
this thread so the item may be from the gas lighting era too.
I have no idea what the item is or was used for though.

That's pretty funny, it does look like a belt buckle, you might have nailed
it.

I agree. I didn't notice the small hole in the end of the leg of the T.
Adding a screen into the "bowl" would be all that was needed for a
hash pipe.
Good call.

If in fact 2427 is an arm exerciser, it would have been called an iron
shoe.. They are that shape and this probably could have been used in this
fashion. But most of the iron shoes I have seen are much simpler and had
just a spring across the two arms. But this does look like it has a very
similar action. Judging by the age, style, etc., it would have been a high
end model of an iron shoe if it was in fact an iron shoe. Perhaps it was an
original model and they came out with the cheaper version later with just a
spring across the two arms. These were quite common a hundred years ago and
the cheap version were sold up to about 30 - 40 years ago. I remember
seeing them in gyms as a kid.

Here is an old ad for one.

<http://books.google.com/books?id=wygDAAAAMBAJ&pg=PA116&lpg=PA116&dq=%22iron+shoe%22+exerciser+arms&source=bl&ots=XkFvfkXw02&sig=HuT9njB_J8gx30WML3Ac8sitWQY&hl=en&sa=X&ei=WATsTu34MoKRiQLi89GIBA&sqi=2&ved=0CEMQ6AEwAg#v=onepage&q=%22iron%20shoe%22%20exerciser%20arms&f=false>

They were called an iron shoe because they resemble a horse shoe. I tried
to find more info on them but this is an old item and they are just not out
there any more. I did find a few folks who remember them and wanted to find
them. Old ones are prized by collectors of strong man memorabilia.

[Rob H.]

Thanks, I think that iron shoe is correct, this will be my answer until I
see evidence to the contrary.

>I have seen one of these, and my (questionable) memory suggests a
shock absorber of some kind. The mechanism allows the force of the
spring to increase faster than if it were simply in-line. Something
like a tow-rope or chain might make use of it.
