Abstract
753,329. Machinery guards. AMAL, Ltd., and HAVILAND, W. F. July 16, 1954 [Sept. 11, 1953], No. 25150/53. Class 80(4) In a hand-operated press wherein a punch 7 is moved by screw means (not :shown) towards a die block 5, a horizontally-slidable guard 37 sweeps over the block at each descent of the punch to remove the operator's hand, &c., from the path of the punch. The guard 37 is carried by a slide actuated by a slotted L-shaped lever 27 whose other arm is engaged by the lower arm of an L-shaped lever 19. A cam 15 on the lever 19 is actuated by a roller 13 on a bracket moving with the punch 7 so that at each descent the plate 15 is moved to the left and, through the interaction of the two L-shaped levers, the guard 37 is moved to the right. A spring interconnects the two upper arms of the levers 19, 27 to maintain the lower arms in contact and effect the return of the guard.
