Abstract: A rifle rest with stop means for respectively releasing and stopping movement of both coarse and fine elevation adjustments and shafts and handles for manipulating the stops. The shafts and handles of the elevating mechanism stops which are outboard of the hub region of the rest are fabricated from hollow tubing to reduce their mass. An adjustable bias in the releasable stop for the coarse elevation adjustment is provided to control manipulation of this adjustment.

Abstract: An improved breech lock adapted for locking the barrel and slide of a handgun together to provide for improved securement between these parts. Typically, the firearm is of the type having a slide and a relatively movable barrel along with a handgrip and trigger. The rear part of the barrel has an end configuration or conformation which cooperates with an opening or recess in the upper part of the slide. In the preferred form, the barrel has an end conformation, the forward part of which is shaped as a point configured to be received snugly in a V-shaped opening in the forward end of the recess in the slide. The breech lock provides for locking as between the slide and the barrel, preventing relative forward movement of the barrel with respect to the slide and further locking with respect to relative lateral movement as between the parts or vibration which could effect the accuracy of the firearm.

Abstract: A feed hopper for shell casings for use with a cartridge loading machine. The hopper is in the form of a container having curving interior surfaces, the surfaces extending to a feed aperture at the bottom of the hopper connected to a feed tube. Preferably the hopper is of hemispherical shape. The hopper has a transverse member positioned diametrically across it over the aperture to prevent a casing from being dropped into it so that it could fall into the feed tube with its open end down. The configuration of the hopper causes the casings to feed steadily with the rim down into the aperture and the feed tube.

Abstract: A sliding charge receiver is slidably positioned under a powder feed hopper for receiving a charge from the hopper and delivering it to a feed chute. The sliding member has a hole to receive a powder charge from the hopper. The hole is adjustable in size by a safety adjustment. The hole is formed in the end of a slot. A secondary slider is movable in the slot to adjust the size of the hole. The secondary slider is on a threaded stem within the slot which is threaded through a rotatable bushing or rotor. The stem can be locked in position by an elongated nut that extends through a hole in the end of the sliding member. By releasing the elongated nut, the secondary slider, threaded stem and rotor can be rotated, moving the secondary slider out of the slot so that the secondary slider and stem can be rotated to provide fine adjustments of the position of the secondary slider and of the charge hole in the sliding member with assured safety of the adjustment.

Abstract: A manual cartridge loading machine. The machine has six stations at which cartridges are operated on. Cooperable with the stations is a manually actuatable head carrying dies which execute the operations on the cartridge cases. The operations which are executed at the stations include: feeding the cartridge case; sizing the case and removing the old primer; belling the mouth of the case and seating the new primer; feeding the powder; feeding the bullet in the case; and taper crimping the case. Cartridges are shifted from station to station by a manually actuatable shifting plate which is constrained for quadrilateral movement, that is, in and out with respect to the stations, and right and left in a direction parallel thereto. A safety latch is provided so that the head cannot be manually pulled down unless the cartridges have been shifted by the shift plate.
