  • Patent number: 4217809
    Abstract: In a system which sizes and lubricates lead bullets, an indexing plate, being chain driven, and having an indexing post, is mounted horizontally and in such a manner that the indexing post engages indexing detents in a transfer plate, having a plurality of bullet receiving holes. The transfer plate also mounted horizontally, and which has circular scallops whose radii and centers of curvature are coincident with the contacting surface of the indexing plate, providing an indexing to the transfer plate and a positive lock in between index positions; and a lubricating mechanism using a harmonic motion thus providing a lubricating piston with a long time in which to exert nearly maximum pressure on the lubricant and thereby optimizing the lubricating stroke; all being properly timed with the proper movement of the punch; so as to provide simultaneous and high speed sizing and lubricating of bullets.
