Abstract

812,859. Door-operating appliances. PREPARATION INDUSTRIELLE DES. COMUBUSTIBLES. March 14, 1957 [Aug. 14, 1956], No. 8485/57. Addition to 795,571 [Group XXXVI]. Class 65(1) [Also in Group XXX] The door of a skip in a skip hoist according to the parent Specification is closed by a hydraulic device which stores energy as the door is opened. As illustrated the door is connected by a pair of connecting rods 6 to rollers 8 running in guides 9 on the skip, and a single acting hydraulic ram 11 connected at 10 to the connecting rods 6 is connected to a hydro-pneumatic accumulator 12 which stores energy as retracting fingers (not shown) carried on the hoist framing and engaging the axle of the rollers 8 open the 'door. A valve 13 permits the door 1 to be locked in its closed position and may be operated manually or by cam surfaces mounted in the hoist shaft. The invention may be employed in connection with other constructions shown in the parent Specification. Two rams may be employed in place of the single ram 11 shown.
