Abstract
464,590. Machinery guards. UDAL, J. D. Jan. 1, 1936, No. 22. [Class 80 (iv)] A press guard of the forward-swinging type is so constructed and arranged that it can strike the operative's body below the hands or arms. In the form shown in Fig. 2, the horizontal bars b are below the arms during the placing of the work pieces on the die h, and, if the operative is too close to the machine, will push him away. The bars b may be mounted in any of the holes l in the side bars a of the guard and the bearings d are adjustable on brackets e. In a modified form the rising motion of the guard is derived from a pivoted pawl, which, just before reaching its lowest position, slips past the free end of an actuating lever, so that the guard falls back. The guard may be pivoted at its lower edge, on a spindle c, Fig. 6, and may have telescopic side members a, a<1>. The operative stroke of the ram g is the upward one and the arms of the workman when feeding the machine are above the guard. The upper ends of the sides a<1> are connected by two flexible bands which form the guard proper and are secured to fasteners b<1>.
