Abstract

121,793. Embree, H. Dec. 31, 1917. Reciprocating - saw machines. - In a machine for sawing or broaching metal, and stated to be applicable for keyseating, dovetailing, gear-cutting, and similar operations, the tool 6 is held in a vertical frame 5 reciprocated bv a crank 15, and a slidable work-table 17 is fed intermittingly by a cam 13 and a spring 47 so that the work is fed resiliently by the spring during the cutting stroke and the pressure on the work is relieved during the idle stroke. The table 17 is provided with a rack 18 in gear with a pinion 19 on a shaft 20 upon which a hub 24 is secured. A collar 25 adapted to be rocked upon the hub by the spring 47 and the cam 13 is provided with a wedging-roller 28 which causes intermittent rotation of the hub. A similar roller 36 turns a ring 31 until this is arrested by a fixed pin, not shown on block, which engages in a slot in the ring, whereby a standard rate of feed is determined. If a slower feed is required, a threaded rod 54 is adjusted by a handle 53 to act as a stop to the train of levers. The rollers 28, 36 are carried by disks 26, 32 which are provided with handles 32 whereby the work may be withdrawn from the tool if necessary during its cutting stroke. The feed tension is adjustable by a drum 48 and a handle 50. Interchangeable blocks are positioned in the table 17 which are provided with slots wherein the tool reciprocates, the slots being of widths to accommodate different tools. A fixed bracket H carries an adjustable stop 57 for the table 17.
