  • Patent number: 4228724
    Abstract: A press type ammunition loader in which the casings are sequentially advanced through a series of work stations by means of a shuttle bar which is reciprocated along the line of the work stations and also moved laterally into and out of engagement with the casing series. A simplified shuttle bar operating arrangement is disclosed including a cam actuated hitch-index shuttle cooperating with other shuttle bar operating components operated by reciprocal movement of lower and upper platen plates which also operate the respective loader components at each work station. The shuttle bar advance and return movement is executed while engaged with C-form springs, maintaining an inward bias force. The upper and lower platens are reciprocated by rotation of a crank-link assembly, which also operates a primer feed slide mechanism, by means of a cable and pulley drive moving a primer slide bar between primer pick up and seating positions.

  • Patent number: 3967526
    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. Semifluid lubricant is fed from a pressurized supply into the die chamber by means of a cam driven pump plunger so as to fill the lubricating rings of each slug as it momentarily rests within the sizing die chamber. 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.
