3055) Memories of being a kid! :-)
This is the ringing generator used in old phones to ring up the
operator at the central office.
it has been butchered, however. Note the different color of the
metal in the center of the large gear. It should have a fitting
there for a crank which extended through the side of the wooden
box mounted on the wall. The center of the gear had a threaded
stud sticking out, onto which the crank threaded.
Interesting -- this one *does* have a square stud on the other
end of the shaft, so a crank could be slid onto that to allow it
to be cranked. Perhaps goes along with the red paint job on the
The crank turns the large gear, which spins the smaller gear
more rapidly, spinning an armature between the poles of the
horseshoe magnets (painted red in this example, though they were
usually painted black since they were hidden inside the box.)
It was obviously set up to be mounted to a bench -- likely in a
school physics lab.
And I suspect that the crank was sawn off prior to offering it
as an antique item -- likely to prevent people getting nasty
shocks from it. It has been used by kids to shock other kids
(guilty), and has also been used as a form of torture (not
3056) Made for Craftsman (Sears) by who knows.
Looks as though it might serve as a vise for sharpening saw
3057) This is a collet for holding burrs in a flexible shaft tool,
or perhaps a hand-held tool. It looks a little long to be for a
Dremel, but it is for a similar tool at least.
3058) An interesting tool. At a guess, it is for woodworking, with
the edges marked 'd' and 'v' for smoothing respectively curved
surface and flat surfaces. The other two edges might be for
stripping off bark as an earlier operation.
3059) At a guess, it expands inside something to allow it to be hung
from a scale. Likely fish but perhaps a side of beef or
something like that.
3060) A tool for preparing apples at a guess. It at least cuts
slices and discards the core. And it looks as though it also
peels the apple first.
Looks like a good thing to have if you want to turn a bushel of
apples into a number of apple pies.
Now to post and then see what others have suggested.
3055, by some odd coincidence, I have one of these
on my kitchen table, now. Mine has a better crank
handle than the one you show, and is in a bit
better shape. I know what it does, but not "it's
a XX that goes onto a YY" level of detail. I'd be
happy to send you pictures, if you wish.
3056, don't know.
3057, some kind of leather punch?
3058, don't know
3059, maybe help carry tubing of some kind? Squeeze, and put the pointy
ends in the tube?
3060, maybe apple peeler, and slicer?

Actually the magneto was for more than signaling the operator. If you
wanted to call someone on your line, a neighbor, perhaps. You didn't
call the operator. the operator could not help you. You needed to ring
the other person on your line. Perhaps two long rings and a short, or
three shorts rings. Every subscriber on a given line heard all the rings
whenever someone was being called. Every subscriber had their own unique
signal code. In fact they could pick up the receiver and listen to the
conversation and even add their comments at any time. The good old days!
I hadn't thought of that. I think two points would puncture tissue
instead of spreading it.
Assuming the ruler is an inch wide, it appears that the pointy toes are
about 3.5" apart. The "legs" appear to be about 2" apart, outside to
outside, at the "ankle." If they were squeezed together, it appears
that the "toes" would be 2" apart.
If the slotted piece were slid down, perhaps it would hold the legs
I picture a cylindrical container the size of a 46-ounce juice can. In
the center of the flat top, it has a neck 2" in diameter and 5" long.
If you collapsed the legs and shoved the tool down until one of the toes
got under the flat surface below the neck, then let the legs spread, the
other toe would come out under the flat surface on the other side. Now
you could hang the container securely.
I wonder if it was to hang a container, or maybe to extract a mechanical
part with a tube 2" in diameter.
It's curious that the "toes" aren't 180 degrees apart.

But in which newsgroup? This is cross-posted to three
newsgroups. (I know, you are active in rec.crafts.metalworking too, but
the idea was to try to associate what kinds of answers come from people
in which newsgroups.
Yours has a crank which screws onto a threaded stud in the
center of the big gear, I suspect.
And -- when it is turned, a projection extends out the other end
of the shaft, closing an electrical contact.
If it is as I described (and likely black paint on the horseshoe
magnets, instead of red paint), then it almost certainly came out of an
old wall-mounted telephone. You cranked it to send a ringing signal
down the line, to get the operator's attention. (Or, to ring other
phones on the same party line, to make very local calls without the help
of the operator. :-)
The one in the puzzle, with the square projection on the far end
of the shaft is likely intended to be used in something like a school
physics/science lab, thus the fancy red paint on the magnets. (And, it
allows the teacher to lock away the crank, to prevent mis-use of the
generator -- or at least to make it a bit more difficult. I could
imagine the teacher doing that in self-defense, given the way kids act.
(I was one. :-)
I don't need one, but perhaps the fellow who posts the puzzles
would appreciate it.
