A semi-automatic cartridge reloading machine of the type including a lower travelling platen with a rotatable support for sequentially positioning a plurality of cartridges in each of a series of operating stations and including an upper stationary platen with a plurality of tools or dies depending or extending downwardly and spaced circumferentially about the upper stationary platen and centered over the rotatable support defining a plurality of operating stations is provided with mechanisms for automatically rotating the support to reposition the cartridges in subsequent operating stations at the completion of each reloading step or operation, automatically centering cartridges and removing spent primers from cartridges, automatically belling and admitting powder into cartridges, automatically introducing and inserting new primers into cartridges, automatically introducing and inserting bullets into cartridges, and automatically crimping and seating bullets into cartridges simultaneously and in conjunction with the raising and lowering of the lower travelling platen. All mechanism are synchronized so that cartridges may be operated on and reloaded from start to finish without the necessity of manual intervention.

In a semi-automatic cartridge reloading machine in combination: a base structure, a lower travelling platen supported on the base structure, a positioning mechanism for raising and lowering the lower travelling platen relative to the base structure, a indexing table and shell holder plate supported by the lower elevating platen and defining a plurality of operating stations spaced circumferentially about an imaginary circle having a vertical axis, a plurality of shell rim slots equally, circumferentially spaced about each shell holder plate, each of such shell rim slots being adapted to receive a separate shell casing, and to position such received shell casings simultaneously in different ones of the operating stations, a stationary upper platen containing a plurality of tools or dies depending or extending vertically through the stationary upper platen and defining a plurality of operating stations spaced circumferentially about an imaginary circle having a vertical axis, the improvement of an indexing drive mechanism which operates simultaneously with and in conjunction with the raising and lowering of the lower travelling platen and is engageable with the indexing table and shell holder plate for rotating the indexing table and shell holder plate to position shell casings received in the indexing table and shell holder plate sequentially in each of the operating stations comprising in combination: a. a clevis secured to the base structure; b. a bar pivotally secured to and extending upwardly, vertically from the clevis; c. a bar slot formed in the upper end portion of the bar to accept a crank pin; d. a crank pin which travels upwardly and downwardly in the bar slot simultaneously and in conjunction with raising or lowering the lower travelling platen by the positioning mechanism; e. a curvilinear shaped crank extending axially from and secured to the crank pin at one end which rotates in one direction as the crank pin contacts the top or bottom of the bar slot and having a pinion pin secured and extending axially at the other end; f. a housing extending radially from the circumference of the lower travelling platen which journals and supports the pinion pin and pinion; g. a pinion comprised of a plurality of gear teeth positioned within the housing and journalling and secured to the pinion pin which rotates correspondingly with the rotation of the crank and engages a rack; h. a rack comprised of a plurality of corresponding gear teeth formed in the underside of one end of an indexing ram which travels in a horizontal plane across the pinion as the pinion is rotated and correspondingly slides the indexing ram into and out of the lower travelling platen; i. an indexing ram with a rack formed in the underside of one end of a pawl pivotedly secured at the other end which slides into and out of the lower travelling platen on rotation of the pinion; j. a ram slot formed in the top surface of the lower travelling platen to accept the indexing ram and extending from the circumference to the center portion of the top surface of the lower travelling platen; k. a pawl pivotedly secured to the end of the indexing ram which drivingly engages and rotates a ratchet secured to and extending axially from an indexing table center pin; l. a ratchet secured to and extending axially from an indexing table center pin and recessed into a recess hole formed in the top surface at the center portion of the lower travelling platen; m. a recess hole formed in the top surface at the center portion of the lower travelling platen to accept the ratchet and indexing table center pin; n. an indexing table center pin positioned vertically within a recess hole secured to a ratchet and secured to the indexing table and shell holder plate to rotate the indexing table and shell holder plate to move and position shell casings between adjacent operating stations as the ratchet is engaged by the pawl on each cycle of operation; p2 o. a pawl return spring positioned within a spring hole formed in the pawl end of the indexing ram and biased against and between the pawl and an adjusting means set in the indexing ram to return the pawl to rest position after each cycle of operation; p. a spring hole formed in the pawl end of the indexing ram to accept the pawl return spring; q. an adjusting means set in the pawl end of the indexing ram to adjust the pawl return spring; r. a pawl stop screw disposed at and extending into a stop screw hole formed in the pawl end of the indexing ram which engages the pawl and may be adjusted in and out of the indexing ram to correct for wear to the pawl or ratchet; s. a stop screw hole formed in the pawl end of the indexing ram to accept the pawl stop screw; t. a key slot formed through the center portion of the indexing ram to slide across a register key correspondingly disposed in the ram slot which enters the key slot on each cycle of operation to assure stop lock action of the rotation of the indexing table and shell holder plate; u. a register key disposed in the ram slot biased vertically, upwardly against the indexing ram by a register key spring and positioned to enter the key slot formed in the indexing ram on each cycle of operation; and v. a register key spring secured to the underside of the indexing ram to bias the register key vertically, upwardly against the underside of the indexing ram.
