Abstract

831,702. Operating doors of skips in hoists. PREPARATION INDUSTRIELLE DES COMBUSTIBLES. Dec. 31, 1957 [Feb. 20, 1957], No. 40495/57. Addition to 795,571. Class 78 (4). The door of a hoisting skip similar to that of the parent Specification is opened and closed by catches 9, 10 on a retracting guided carriage operated by a ram 13 on the hoist framing and serving also to lock and unlock the door. In the construction illustrated, the catches 9, 10 serve to move a shaft 2 running in guides 8 and connected by links 1 to the door. When the door is closed rollers 6 carried by spring-biased levers 5 on the ends of the shaft 2 engage in horizontal extensions of the guides 8 to lock the door. When however the operating carriage is moved upwardly from its retracted position on a portion 12 of its track 11 the catches 9 engage further rollers 7 on the levers 5 to turn the levers to the position illustrated in which the rollers 6 are aligned with the straight portion of the guides 8. The inclined surface of the closing catch 10 returns the rollers 6 to their locking position so that the catch 10 can pass below the rollers 6 after they have entered the lower portions of the guides 8. The operation of the ram 13 may be interlocked with the winding engine control.
