Abstract
346,167. Controlling machinery guards. UDAL, J. P., 91, Oakfield Road, Selly Park, Birmingham. April 10, 1930, No. 11397. [Class 80 (iv).] Press &c. guards of the outwardly-swung type are actuated from a crank c by a short connecting- link d and relatively-long inclined lever-arm b secured to the guard-spindle a, the parts being so arranged that the guard is fully actuated during less than one half a revolution of the crank c, as shown. In a modification, the arm b is nearly vertical, being disposed in front of the crankshaft. For presses rotating in the opposite direction to the arrow, the arm b is shorter than the distance between the axes of the spindle a and crankshaft. The guard, as in Specification 214,899, [Class 80 (iv), Mechanism &c.], comprises an upper frame e on the spindle a and a lower frame f pivoted thereto and constrained by a link g connected to a fixed point h. The frame f carries a handstriking bar j. A further spring-controlled guard element i may be pivoted on the frame e.
