Abstract

669,102. Machinery guards. SHARP, D. C. March 13, 1950 [March 14, 1949], No. 6853/49. Class 80 (iv). A movable portion of floor a adjacent a bending press or like machine is supported by sheaves d bearing on spring-tensioned horizontal chains or cables e, e', so that the weight of a person thereon moves the floor and stops the machine. The cables e, e' are anchored at f, f<SP>1</SP>, pass over fixed sheaves g and are tensioned by spring devices j, j<SP>1</SP> which act on levers m, m<SP>1</SP> engaging stop switches o, o<SP>1</SP>. Emergency stop switches n, n<SP>1</SP> are operated if a cable breaks. Fixed stops p engage the upper surface of the floor and links l, l<SP>1</SP> prevent longitudinal movement thereof. In alternative arrangements the tensioners j, j' may disconnect a clutch and apply a brake, or may operate on gearing or on a differential pulley or sprocket to disconnect the drive to the machine. The stop mechanism may be remote from the machine and connected thereto by a cable or other means. Counterbalance weights may replace the spring tensioners and movements of the floor itself may operate the stop switches.
