1521 Battery tester. The thin v-shaped piece is a current-shunt or load
resistor. Push the points into the lead posts of a storage battery cell.
The bottom end is a meter that reads the voltage under load.
1524 Blow torch... Not helpful, as I've no idea what specific application it
is intended for.
1519 - ye olde Change-O-Matic. I wish I had one some days. Load it with
loose coin change and push the buttons to dispense change. Looks like
quarters, nickels, dimes, pennies. L-R
1520 - Axe/Hammer/Maul other handle wedge.
1521 - Battery Load tester. Points go to battery terminals, V shaped
item is the current shunt, meter under clear handle cap reads capacity.
1522 - Looks like a pin spanner with 4 preset sizes. Might be for shaft
seals or packing adjustment.
1523 - Lab Glass handle?
1524 - Soldering iron heater. Missing the iron that would set in the
saddle. Unlike the common pump style blow torch this was intended only
for soldering iron use.
My guesses this week, feeling a bit clueless as usual.
1519 - Device to dispense coins or coin-like tokens individually at a
1520 - Wedge to hold an axe or maul head on the handle of same. I'm not
sure it would be much more effective in practice than the traditional
wooden wedge, but it's hard to patent a wooden wedge.
1521 - Possibly a device to temporarily jumper an electrical connection,
say while replacing or inspecting a fuse?
1522 - Maybe a gauge for checking engine pistons for wear, adaptable to
four different piston sizes or measurement points (e.g. outside
diameter, diameter in ring grooves, ...); although I would have thought
that a vernier caliper would be just as easy and useful and more
generally applicable for this operation when overhauling an engine, and
a production line gauge not adaptable to various sizes, so I'm not at
all confident in this guess.
1523 -- glass blower's forming tool to make necks, etc.
1524 - Burner for heating soldering irons before electrically powered
ones were commonly used.
"He is no fool who gives what he cannot keep to gain that which he cannot
1519 looks a bit like a coin dispenser.
1520 not sure what they are called but it gets knocked down the shaft of an
hammer to secure the head in place.
1521 I guess at some kind of moisture detector for soil.
1522 looks like a caliper with 4 settings.
1523 i will guess at grip for a small crucible making for use with jewelery?
1524 oil burner? I would have thought there would be somewhere to plug an
air supply in for oil so maybe parafin powered or something.
Posting from rec.crafts.metalworking as always.
1519) Looks like a coin dispenser. I would like to see more angles
of view, but it looks as though it is (from left to right)
and you either push or pull the handles to dispense one coin of
that size at a time.
I suspect push, with a tray on the other side to capture the
1520) A wedge to drive into the wooden handle of a tool to secure the
head to the handle, perhaps a sledge hammer, axe, or something
like that. I think that it is a bit large to be for a standard
1521) Meter for checking the state of charge of a single cell in a
multi-cell lead acid automotive battery. Typically, the old 6V
ones had cross links connecting the cells buried under tar, and
the points went through the tar to connect for the test.
The 'V'-shaped part is a shunt to draw enough current to make
for a meaningful measurement.
There is a meter in the end of the handle.
1522) This is a wrench for gripping threaded rings with an even
number of holes (so there will be pairs 180 degrees apart).
these may be for securing optical components in microscopes
or something similar.
While nothing shows it -- I'll bet that the assembly with the
rotating rectangle will slide on the handle to make for fine
adjustment of the spacing of the pins. Rotating the rectangle
makes coarse adjustments to get close to the right size.
Once the pins are in the opposite holes, the handle can be used
to rotate the ring to tighten or loosen it.
1523) Looks as though it is for picking up a hot flask and pouring the
contents. Something like a chem lab Florence or Erylmyer flask,
or perhaps even a simple test tube. But it looks as though it
could handle something quite hot, such as a container of melted
1524) Looks like an interesting variant on a blowtorch -- especially
configured for heating a soldering iron.
Now to see what others have said.
