Abstract
583,302. Machinery guards. HUMMERSTON. F. G. Oct. 17, 1944, No. 20071. [Class 80 (iv)] The guard 10 of a machine having a treadleoperated reciprocating tool 3, is actuated by a treadle 17, independent of the machine operating treadle 4 so that while the operator's foot depresses the guard treadle 17 the guard 10 is raised, but when the foot is moved to the operating treadle 4, the guard 10 moves to the guarding position. As shown, the treadle 17 is connected to a slide arm 9 on the guard 10 by a lever 13 and rod 16. The guard may move to the guarding position by gravity with or without the assistance of a spring 18. The rod 16 may be of adjustable length, and the tension of the spring 18 may be varied. The guard 10 may move laterally instead of vertically.
