Filed: 1946-07-02
Abstract: 614,041. Machine safety devices. STANDARD TELEPHONES & CABLES, Ltd., BAKER, J., and KITCHING, W. F. July 2, 1946, No. 19741. [Class 80 (iv)] A safety device for a machine such as a press with a reciprocating tool, comprises an arm L which is swung in front of the danger area of the machine by means of gearing A, M, N from the reciprocating part P of the machine on its downward stroke. Both the gear A and the arm L are freely rotatable on a fixed shaft B and a certain amount of relative movement between them is allowed by a spring coupling device H. Should the arm L be obstructed by, for example, the operator's finger, this coupling gives and a roller G carried by the arm L is moved into locking engagement between the shaft B and a cam slope S of a recess D in the gear A which prevents further downward movement of the part P. The movement of the part P has to be reversed to release this locking action. Instead of a direct locking of the machine by the roller G, an electrical controlling switch or cut-out may be actuated on relative movement of the arm L to the gear A.
