1289- high current ammeter. The meter is a voltmeter/millivoltmeter,
and measures the voltage drop across the short section of metal bar.
-or-
A force guage- the metal prongs go into 2 pieces that get pulled apart
or pushed together, the meter is a mechanical movement that amplifies
the tiny amount of strech or compression in the bar.
I think a hammer like the one shown has been on here before, but I'm
not going to 'cheat' and go look it up...

It isn't a rangefinder, the device is used for recreation and doesn't really
have a useful purpose, although I guess you could do some types of
experiments with it.

The guy who was selling it told me that it was for barrels, but the biggest
indicator is probably that it was in box with about ten or twelve other
cooper's tool that he had bought from someone. As was mentioned, I'd guess
it was for smaller barrels.

1289. Finally something I have actually seen! Used in olden days to put a
high current load on a 2 volt cell in a car battery and measure the voltage
under load conditions.
I'm glad to see you have given up on the Roman numbers, ... again. I hope
it lasts this time.

It surprises me that a cooper would have used 1290. The arc in the
metal looks too small. Wouldn't the side of the barrel mash the rope
against the sides of the holes?
The rope doesn't look long enough for a keg more than 12" in diameter.
It looks as if the cooper would have to slide the lever twice in each
revolution. If the lever against the barrel is what stops the windlass
from unwinding, it looks as if the cooper would have to tighten in
increments of more than 2".
A strangle knot seems perfect for holding a barrel together. If you
need more pressure, you can make a similar knot with more loops.

You got me curious enough to look up barrel making. You start by
stacking the staves and slipping a hoop over the top. I think it's a
temporary hoop.
Now you have a sort of cone, wide at the bottom because the staves are
wide in the middle. The next trick is to pull the staves together at
the splayed end, enough to get a temporary hoop over the end. Perhaps
the process could take days, shortening the cord by 2" at a time. I see
why the windlass was made that way.
An alternative would be a sort of strangle knot -- sort of like a clove
hitch. Instead of using a lever to increase tension on the rope, you
increase pressure by taking more turns around the barrel.
I see advantages over the windlass:
1. Longer rope life because there are no sharp turns.
2. Smaller, cheaper cordage can be used because less tension is required.
3. No fooling with a windlass, just form the loops and tug.
Years ago I tried a similar knot with three or four turns around my
thigh. It came loose easily when I pulled the right place. Still, I
was glad I had a sharp knife available in case it didn't come loose. A
simple tug had tightened it so much that it cut off my circulation.

Let's see...
1289 - I'd really like to see the opposite side of the round box in the
middle, but maybe that would give too much away. At first glance, this
appears to be a spanner or gear puller, but the overall design doesn't
seem quite right for that in the general cases: if a spanner, the
handles aren't spaced to provide too much leverage, especially given how
strongly the rest of the unit appears to be constructed; and if a
puller, it seems to be missing the rather essential pulling apparatus.
Maybe this is some office tool used to bind papers into impromptu books,
rather like a ring binder but using some other technology.
1290 - Clamping device for round stuff; maybe to bind shocks of grain or
broom heads together, or maybe a tourniquet for extreme first aid of man
or beast. Rotating the axle winds or unwinds the rope, which seems to
pass through the middle of the crescent-shaped part. Constructing one
would be an interesting project in drilling and shaping wood.
1291 - A hammer of some sort. Assuming the head alone is 4.5" long (and
not the handle), it's for...ummm...maybe fencing? If the entire thing
is petite, it may be a punch for patterning wood carvings.
1292 - Stropping machine for straight razors or other keen knives,
missing a leather belt?
1293 - Some specialized distillation apparatus; it appears the
condensate is intended to be collected in the upper glass jar with a
spout, and overflow into the lower jar. Perhaps this was for
determining the potency of alcoholic beverages for taxation purposes.
1294 - Optical rangefinder or angle finder--probably angle finder, as a
rangefinder should have two relatively widely separated lenses that are
optically superimposed, rather than a single centralized one.
Rather a tricky set this time for me.

Still having problems with the images showing up on opera
depending on the size. I wonder what blogspot changed in the wrappers
of the web page to bring up this sensitivity?
1289) A charge meter for a single cell in an old style automotive
battery. The points stick through the tar covering the bars
connecting one cell to its neighbor, a *lot* of current flows
through the square bar (I suspect nickel plated copper), and
either the resulting magnetic field deflects a needle connected
to a permanent magnet, or there is a real meter movement in
there which is measuring the voltage between the two pins or
screws which secure the meter movement to the bar.
1290) A device to bind a group of rods or sticks together in the loop
of rope coming out of holes in the cast iron part.
1291) An interesting hammer -- but no clue why the deep slots at
right angles in one face.
It looks as though it is held in contact with something while
another hammer strikes the un-slotted face.
1292) AT a guess -- a tool for moving leather belts and holding them
while they are decoratively tooled.
Or maybe for holding machine driving leather belts while they
are being joined.
1293) It looks like an incomplete still -- probably for purifying
water in small quantities.
1294) A stereoscopic viewer, or an optical rangefinder.
Now to see what others have guessed.
Enjoy,
DoN.

That depends on the size of the barrel. I remember having one
as a kid (yes, a real barrel with wood slats and metal hoops) which was
only about 4" ID at the ends, and 6" OD in the middle.

Let it pass free over the end, and tighten the barrel and slide
on the hoop. Loosen a bit, slide to a larger diameter, tighten and
slide on the next hoop. Flip the barrel over and repeat from the other
end.

You don't have to hold it for long -- just long enough to slide
on the hoop and then progress to the next.

Is it a projector for one of those toy circular stereo viewers?
