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.
