Abstract

610,433. Machinery guards. LEGGE & CO., Ltd., J., LEGGE, F. V., and PENNINGS, B. April 5, 1946, No. 10520. [Class 80 (iv)] A guard D for a hydraulic press is hinged on a vertical rod d and connected through links d<1>, k, K, m and bell-crank levers n to rotatable sleeves J surrounding rods G through the medium of which the moving head B is raised by hydraulic means. Each sleeve J is formed with upwardly extending tongues j<1> and slots j, similar sleeves H surrounding the rods G and carried by the head B, having similar downwardly extending tongues h<1> and slots h. When the guard is closed, the tongues h<1>, j<1> engage the corresponding slots j, h as the head B descends, to lock the guard. The head cannot descend whilst the guard is open, as the tongues h<1>, j<1> abut against each other in this position. The action of the prefiller valve through which pressure oil is supplied to the ram cylinder is controlled by the guard, the rod d thereof carrying a disc P having a cam groove p in which a roller s on a pivoted lever S rides, the other end of the lever S pivotally carrying a rod u which prevents the valve from closing when the guard is open. The invention can also be applied to a vertically sliding guard.
