2845. These are copper crushers or copper pressure cylinders from the Frankford Arsenal, according to this article:

Until the mid 1960's the only method commonly used for measuring chamber pressures was the copper crusher. Basically, a hole is drilled in the chamber of a firearm and a crusher chamber is attached to that hole. In this crusher chamber is placed a very precisely manufactured piece of copper.

When the gun is fired the copper pellet is crushed (deformed) by the pressure to some degree. The amount of this deformation is then precisely measured and a very standardized indication of pressure is determined.

To this day, most published chamber pressure (MAP) data for metallic cartridges is taken by the copper crusher method of measurement. The proper name for this type of measurement is CUP, or Copper Units of Pressure.

Answers:



2839. This is a traveler, or tire measuring wheel, according to the Dictionary of American Hand Tools it was "used to measure the length of flat strap required for making a new wagon tire. The wheel is measured by rolling the measuring wheel around the outside surface and counting the revolutions. The process is then repeated on a straight length of wagon tire iron. An additional amount is added to account for bending and welding."
Though Modern Blacksmithing has a slightly different use for it, which states "Now roll the wheel over the tire. If a heavy tire cut it three inches longer than the wheel, if a thin tire, two inches. Now bend the tire in the bender. Measure the wheel with the gauge, then measure the tire; if it is a heavy wagon tire and a straight wheel cut the tire one-fourth of an inch shorter than the wheel."
