Abstract
746,376. Machinery safety devices. UDAL, J. D., and WATSON, D. B. Mc- NEIL-. April 23, 1954 [April 27, 1953], No. 11532/53. Class 80(4) A safety device for hand, foot or otherwise operable presses comprises a rod a secured at one end to the movable slide b of the press and a pivoted catch e with an aperture f encircling the rod. The catch e is pivoted on a fixed part c and in the position shown in Fig. 1 acts to lock on to the rod a to prevent the descent of the slide. When the catch is raised by a cam h, by a connection k, n to the guard i, for example, into a horizontal position the rod a can pass freely through the aperture f of the catch to allow the slide to descend. Thus descent of the slide whilst the guard is open can be prevented. In modified arrangements a limited amount of movement of the slide is permitted with the guard open to allow work ejectors to operate but the full movement is prevented until the guard is closed.
