Abstract
671,761. Forging tacks. ESSER, P., (trading as MEYOR, ROTH & PASTOR). April 13, 1950 [July 25, 1949], No. 9139/50. Class 83 (iv). Forging-machines; shearing-adjuncts.-In a machine for the production of wire tacks the wire is fed forward for the main feed step and for a secondary feed step for the reduction of the shank by gripping means without release and regripping of the wire. A shaft 10 driven by a pulley 11 rotates through bevel gearing 14, 15 side shafts 16, 17. The shaft 10 carries a crank 24 reciprocating a heading die slide 26 for upsetting the head of the tack. Knife slides 22, 23, are actuated by eccentrics 18, 19 on the shafts 16, 17. On the shaft 17 a cam disc with adjustable swells of increasing height actuates a lever 35 reciprocating the wire feed gripper 38 in opposition to a spring 43. The stroke of the feed gripper is varied by an adjustable screw contacting the rear of the slide which may be fitted with a dashpot device. On the shaft 16 is a cam 27 with adjustable swells for actuating the shank reduction slide.
