It is about 8 inches long = about 200 mm. That makes the front square about
50 mm. square. That makes the vertical distance between the pairs of guide
posts on the front about 16 mm. So one could lay a strip of 16-mm. film
across the front. There seems to be a registration pin. Close the front
with the diffusing glass. With a simple lens and shutter, though I don't
see either, this could be a camera to make enlargements of frames of a
1646 Satirical Guess...
Crowd control implement purchased by the DHS for about $1500.
1648 It would be impolite for me to suggest photoshop.
1646: Another possible use:
When I was in grad school, I worked under a research grant from the U. S.
Bureau of Mines. The work involved (not surprisingly) going into various
coal mines. Most of the mines were okay to visit. They were much like a
typical heavy duty manufacturing environment. I.e. protect yourself from
noise and don't get run down by the equipment and you will be alright.
However there was one coal mine that I remember still (35 years later) as
being a major exception. The coal seam was only 3 feet high and since no
one pays to move extra rock, the mine was only 3 feet high. So we were
duck walking around and still banging our helmets on the roof. The mine
was wet so we were duck walking in the mud. On this visit I was with a
MESA (Mine Enforcement and Safety Administration now MSHA) inspector. He
had a stick very much like 1646. One of the problems in coal mines is that
digging a mine exposes rock layers to moisture and temperature changes.
This can cause the rock layers to delaminate and then fall. For instance a
2 inch layer of rock which might be a dozen feet across will weight several
tons and it will ruin your day if it lands on you. The mine inspector would
use his stick to tap the ceiling. If we heard a hollow sound then we would
quickly move somewhere else.
I don't know which was its original purpose, but I've seen one exactly like
that used for subduing bluefish, on a head boat. Since I have an engine
lathe I prefer my all-aluminum model. <g>
I don't think its a priest. They are usually smaller, and almost
always have a significantly heavier head or else are made of something
with much more mass than wood, such as brass. This looks to be a tire
knocker (which looks very similar to a priest).

I'll buy that.
surely though its use as a tyre knocker is nearly useless.
the pressure can be easily read directly, which is what you want.
tyres fail through a process that gets them hot so a hand on the tread
to feel for a warm one is surely more effective? that's what I use.

If you are hauling an eight axle dual wheel trailer with a
tandem axle semi-tractor, that makes 42 tires you need to
check several times a day. Do you really think a truck
driver uses a tire gauge on all of them each time :)
If you let one tire of a dual set go soft or worse yet flat
and keep on trucking, you'll have a nice fire going before
long. A tire thumper used regularly will locate that soft
tire before it becomes a flame thrower.
It's a tire knocker, sold in just about every truck stop in the US,
Canada and Mexico. They run about 15 bucks.
When you do your pre-trip you walk around the rig and thump every tire.
(there are at least 19 tires you check at least twice daily) You listen
for the sound of the tire when it is hit. A tire with full pressure
almost rings when you hit it, one that is low will make a lower note and
one that is flat just makes a thud.
Do it a few times and you can tell without a gauge. Heat won't tell you
much on a big rig tire. They ALL get hot when loaded.
1645 electron microscope camera?
1646 I'm certain I've held one of these in my hand but CRAFT disease
has hit. removable spoke/handle from some sort of windlass?
1647 at a guess would be a coopers tool for forming wooden barrel
staves and knocking up the barrel.
1648 are two huge crucible tongs. the one on the wheels would be used
to position the crucible near the mould and the underslung handles
used to rotate the holder to tip the melt into the ingate.
the one on the walls maybe to lift a crucible up out of a top loading
1645 - Looks like an early panoramic camera. Could also be one use for
1646 - "Tire Buddy" brand tire knocker. Used to thump tires on big
trucks looking for low/flat tires by the different sound they make.
Technically illegal in many states as it falls under the "any other
1647 - Looks like something a cabinet maker might use to set inlaid panels?
1648 - LARGE iron worker tongs. The pair on the cart look like rail
alignment tongs. The others look like splitter tongs but the lower jaw
isn't real clear.
1649 - Looks like the end of a connector on a rope harness for horses/oxen.
1650 - Boker Cop Tool, I have that exact same tool. Works OK but I like
the folding one they make better. Takes up less space in my turnout
pocket. (Jim Wagner Rescue Knife for those interested)
