Abstract
155,553. Schneider et Cie. Dec. 18, 1919, [Convention date]. Operating doors hydraulically.- Door-operating mechanism normally actuated by fluid pressure and provided also with hand actuating- means is provided with a cock G, Fig. 1, which is caused to establish communication between two ends of the fluid cylinder C by the operation of the hand actuating-means, but at other times leaves them connected to pressure distributing means A. When a handle h on the wheel H is turned down, a spring bolt c is allowed to engage a toothed wheel P and the hand-wheel is thereby locked to a shaft carrying one member K of a claw clutch. Rotation of the hand-wheel in either direction first causes the other member J of the clutch to be forced back against the action of a spring L and then rotates the member J and its shaft I which is geared to the device B which is to be operated, the longitudinal movement of the member J operating the cock G through bell-crank levers R.
