2319: This is surely a drywall saw, used for cutting rectangular holes
in something, if not drywall. You cut one edge with the end of the
then when you get to the corner, dive deeper and use the second set
of teeth to start the next side.
2322: A marking gauge, used on circular or curved pieces. Perhaps
used by a cooper, for making barrels.
I think you're right about the purpose of the saw, but I'm not sure
about the drywall part of it. That saw looks like it predates drywall
by a couple or few decades. The different angles of the sets of teeth
would indicate that there's a lot of use with the back part with the
finer teeth. The saw is designed to enter quickly and cut roughly,
and then smooth out for the main part of the cutting. Wouldn't work
too well on flooring - maybe a paneling saw and possibly a saw used
for cutting fiber board.
Nifty tool, that. It's possible that it's meant for laying out lines
for pin striping for coach building or something like that.
2317 looks as if it could produce 10 gallons a minute at 1/2 psi. That
would lift water about a foot, so it wouldn't be a typical bilge pump.
With no horn, it looks too quiet for a foghorn.
Some reed organs had pedal boards and needed an assistant to pump
bellows. I wonder if this was for a reed organ that used higher
pressure than bellows could deliver.
2317 A fire Extinguisher?
2318 no guesses
2319 dry wall saw, with side cutter to add the box for switch or power?
2320 chocolate bar pump?
2321 Not sure, but it look like the loop piece was added to keep the
main piece from getting lost
2322 jig for making picture frames?

Remind me to put on my glasses before doing this stuff. I thought the
saw blade was a flat plane. Sigh. The different sections with rip
and crosscut teeth on perpendicular planes are a giveaway - it has to
be for cutting wood. The saw would allow someone to drill only one
hole to cut out the center to make an opening in a panel. Really good
idea. Probably a bitch to sharpen and expensive to make.
The funky saw is for cutting box joints and dovetails the fine teeth
crosscut the coarse rip.
The Big pump looking thing is a foghorn.
And the little pump can is for solvent, an instrument or watchmaker
can wet a swab with solvent.
Posting from Rec.crafts.metalworking as always:
2317) This looks like a form of bilge pump for a small
to medium sailboat -- designed to pump out onto the deck and
flow over the sides of the boat. This is why it does not have
a fitting for a hose.
2318) Looks like it is intended to measure the angle between two
lines radiating from a single point. The single point is placed
under the magnifier in the center (there should be some kind of
cross-hair in there to allow for more precision), and then the
dial and points are used to take readings on lines. It could be
that the second arm and point are to avoid having to shift it to
get readings beyond 180 degrees -- or to get more precisions
from lines passing through the intersection point. (It seems
that the arms are fixed at precisely 180 degrees separation, but
I'm not sure that the arms are fixed relative to each other.
2319) A very interesting saw. It looks like a descendant of a
keyhole saw -- but once it gets the initial starting hole large
enough, it starts a second cut at 90 degrees -- thus
(eventually) making a square cutout.
2320) This looks related to something which I have, which squirts a
solvent against the bottom of a perforated plate in a much wider
funnel or bowl. It is normally used to squirt solvent onto a
cleaning pad, with the rest draining back into the container, to
minimize fire risk -- as the solvent is usually quite flammable,
and it might also be somewhat toxic to breath.
However -- this one looks as though it is designed to squirt a
cleaning solvent into something like a test tube in need of
2321) Either a link pin to allow detaching something from something
else -- or perhaps a hand-made key.
2322) Well ... the centerline of the rectangular stick will pass
through the center of a cylindrical piece against which it is
placed. I don't know whether it has a set of telescope optics
in it for measuring the angle of sight to something else, or a
level to help in finding the center of the cylindrical object.
The trick is getting the two guides set to the same angle,
especially since there appear to be no angle markings on the arc
Now to go see what others have suggested.
Hmm ... I think that is too early for it to be a friction
ignition pin pulled by a cord to fire a cannon -- but it might be
intended for spiking a cannon (driving into the touch hole to deny the
use of the cannon prior to capture.
Nope, not too early, this answer is correct, don't know when they first
started using this type of fuse.
They've all been correctly identified this week, more information along with
some links and several new photos can be seen here:
