1497. Framing hammer
1498. tubing or metal rod bender. the threads are for adding extensions
to the handles for leverage.

1500: The casting looks as if it could have been a fragmentation sleeve
for an early stick grenade. The purpose may have been to use the head
of a grenade as a booby trap. The paddle would have been to secure the
grenade so a trip line would work.

A booby trap could reveal somebody sneaking up on your trench or kill an
attacker who jumped into a crater.

1497. Tool for 'tweaking' 2x4's to align them. Combined with various hammers,
nail pullers, etc.

Posting in rec.crafts.metalworking as always.

1495) Steel rule holders, designed to hold the rule perfectly
vertical relative to the surface plate on which it is resting.
The surface plate is either cast iron or granite, formed to a
particularly flat surface. Depending on grade, the surface may
be flat within one micro-inch.

This particular tool is used for setting a surface gauge
(scriber which slides on the surface plate for layout work.)
You can adjust the starting point of the scale to a gauge block
or a stack thereof to define the starting point. The workpiece
is coated with a layout dye, usually blue or red depending on
the metal involved (selection for best contrast), or for cast
iron, a white coating is used.

The surface gauge is set to height using the scale in the stand
as shown, or one of several other tools which include the scale
and a vernier as part of the device.

The person who would use this is a machinist doing layout work
prior to machining a workpiece.

All of the examples appear to be resting on some white paper
covering the workbench surface, and in front of a stack of
planks, which would suggest an alternative woodworking use for
these tools.

1496) This looks like a very rusty and old pneumatic door closer. It
is attached to the door frame and to the door, and controls how
quickly the door is allowed to close under spring force.

1497) Interesting combination tool. It is at least a hammer, a claw
for removing nails, a one-way wrench to use on two diameters of
pipe, pullers for smaller nails which are not fully seated,
perhaps a wire stripper to remove insulation from electrical
wire, a wrench for two sizes of hex head bolt or nut, and a
point for either stabbing into dirt, or for deburring the ID of
cut off pipe.

1498) This looks to me like part of a folding brace for an awning.

It would appear that yet another threaded part screws into the
socket near the hinge, and the hinge has a ratchet to hold it
opened to various degrees.

1499) Too small -- otherwise I would suggest that it is part of an
early design of handcuffs. Maybe it is for securing a rifle
barrel in a firearms rack -- probably in a military barracks.

1500) Looks like something for holding either flowers or a candle
attached to the wall. If the latter, I think that it is too
close for safety.

Now to see what others have said.

Enjoy,
DoN.

1495. Height gages. I'm going to guess that they were used by pattern
makers for holding "shrink rules" -- rules used for laying out
patterns that are graduated with scales proportional to the shrinkage
of the metal to be cast. Using the proper shrink rule allows the
pattern maker to work to the dimensions of the cooled casting without
calculating the shrink for each feature.

Correct? Wow, I spun my yarn on the basis of the indentations in the
casting!

The French issued pipe bombs on paddles, which the English called
racquet grenades. Apparently the French called them calendiers.

Grenades had been used since the 1600s. In the Crimean War, the British
had made them from soda bottles. If this is a racquet grenade, I think
"grenade" is misleading. I don't think it was made for throwing.

The handle of a stick grenade moved the weight of the head well away
from the wrist, presumably for increased range. This paddle adds weight
but doesn't move the head far from the wrist. Also, the wood would
interfere with approximately half the shrapnel. If it landed at the
enemy's feet with the board side up, the explosion might be harmless.

The handle looks a little wide for a grip. Suppose troops went along 20
yards in front of their trench using a pipe and hammer to make holes in
the ground as wide as the handles. They'd put the handle in the hole,
then tamp dirt around it. Now the wide handle would resist the pull of
a trip line from the iron side of the device.

The troops would probably drive small stakes, perhaps ten yards in
front, to fasten trip lines. Then they would return to their trench and
a specialist would install the explosives and trip lines.

If this is a racquet grenade and a racquet grenade was actually an
antipersonnel mine, the wide board makes sense. It would reduce the
killing radius on the "friendly" side.

Sounds reasonable, though I think I would prefer a thicker piece of wood if
it was meant to protect against shrapnel.

The rest of the answers have been posted, except for number 1498, which is
still unidentified:

Is it about an inch thick? The MK2 "pineapple grenade" had big shrapnel
like the racquet grenade. It could inflict casualties up to 10 yards or
so. I infer that the fragments were slower and more easily stopped than
most pistol rounds.

I wish I knew where to research the paddle device!

It had a Lethal range of 15 yrds...and a wounding radius of about 50
yrds or more.

I have no experience with the MK2. My source is Ledgard's /Soldier's
Handbook, Volume 1/. It says the bursting radius is 10 yards. I took
that to be the limit where it was likely to produce casualties.

I used the M26, an improved grenade with the same weight as the MK2.
They say both kinds can throw shrapnel 250 yards, but there's little
chance of injury. The lethal radius of the M26 was 5 meters. The
casualty radius was 15. Helmets and body armor were excellent
protection. They weren't reliable protection against bullets.

The old pineapple had IRRC, 18 segments that traveled when it burst.
Those could go a fair way, but it was a black powder charge, a low
velocity projectile.

I think the black-powder grenades went out with the 19th Century. I
think the French F1 may have been the original pineapple grenade. Lots
of countries seem to call their grenades F1s. I read about a modern F1
that uses steel balls. The lethal radius is 6m, casualty radius 15m,
and safe radius 30m. That's closer to the 50m you mentioned.

After you mentioned black powder, I was surprised to learn that two
versions of the US MK2 used smokeless powder because TNT could cause
"over fragmentation."

At 2 meters, the surface of a sphere would be about 50 square meters.
If a grenade produced only 18 fragments, it seems likely that somebody
standing 2 meters away would not be hit. (I haven't experimented!)
That seems to be a shortcoming of pineapple grenades.

Slow projectiles tend to transfer their kinetic energy to what they hit,
so it seems feasible that a board attached to a grenade could protect
somebody 10 meters away although the board would be destroyed.

The wood was probably closer to 3/4" thick. I would have answered this
question sooner but I thought I might be able to take another look at it
since I was planning to be in the area where I saw it, but I had a change of
plans and didn't make it out in that direction.
