Abstract: The cartridge case volume measurement system determines case capacity by sealing the internal system volume, and then changing it by a fixed amount. The resulting change in internal pressure of the system is measured and used to compute the volume of the case. The internal system volume includes the volume of the case, the volume inside a master cylinder that is behind a master piston, the volume inside any sensors, tubing, and channels that are part of or connected to the master cylinder. A computing device uses the ideal gas law in conjunction with calibration of the system using cases of known capacity in order to compute case volume from the change in internal pressure resulting from the change in volume.

Abstract: A device for marking the external perimeter of ammunition. The device includes an outer case with an interior portion which includes a plurality of circular rollers that are position to create a recessed channel for ammunition to be placed into. The outer case is equipped with a crank, which is attached to a spindle, which controls the rotation of the circular rollers. One 360-degree rotation of the crank rotates the spindle and the ammunition. The outer case includes a lever attached to an external side of the outer case. The lever is attached to a holder which holds a plurality of marking instruments. When the lever is depressed, the holder and the marking instruments are lowered on to the external perimeter of the ammunition. While the ammunition is rotated, the marking instruments mark the external perimeter of the ammunition. After marking, the ammunition is ejected through the openings in the outer case which are aligned with the recessed channel.

Abstract: An automated machine for lubricating and sizing cast lead slugs and including a body having a slug passage comprising vertical and horizontal legs extending therethrough, the horizontal portion of said passage including a sizing die which insures a uniform slug diameter. A crank-driven ram pushes the slugs through the horizontal leg of the passage intermittently and meters the slugs into the vertical leg of the passage by means of a sliding transfer bar arrangement.

A single motor drives the transfer ram as well as the lubricant plunger so as to synchronize the slug metering and lubricating operations. A ball check valve permits excess lubricant to be discharged from the die chamber.
