Abstract

666,170. Metal-sheet feeds. CLARK & SONS (TOOLMAKERS), Ltd., G. F., CLARK, G. F., CLARK, J. G., and CLARK, R. W. March 16, 1950 [April 5, 1949], No. 9228/49. Class 83 (iv). In a feed device for a press, a slide 3 carries a bracket 21 on which is pivoted on pins 26 a holder 25 for feed-dog 4. Projections 31 on the dog 4 engage the sides of the bracket. A screwed shaft 14 on the slide carries nuts for adjusting the travel of the slide. The pins 26 are connected by links 32 to bell-cranks 36 swung about pins 37 by a shaft 40 connected by links 39, 41. The device is bolted to the machine and on descent of the press head a cam contacts a roller on the shaft 40 to move the link 32 to tilt the holder 25 about the projection 31. The pins 26 slip into rear notches in the bracket 21 and the slide is retracted against the urge of springs 44. On the upstroke of the press the springs 44 through bell-crank 36 and link 32 tilt the dog about the projection 31 to engage the strip, the pins 26 engage the forward notches and the strip is advanced. A spring- pressed dog 49 prevents reverse movement of the strip.
