Abstract

731,941. Operating doors of skips in shafts. RHYMNEY ENGINEERING CO., Ltd., and DAVIDSON, G. W. Sept. 3, 1953 ;[June 20, 1952], No. 15664/52. Class 78 (4). A mechanism for opening and closing the door of a skip in a guided skip hoist may be retracted from its operating position. In the construction of Fig. 1 the mechanism is mounted on a frame 9 which may be turned about an axis 10 by a double-acting pneumatic ram 21. The mechanism comprises a carriage 13 running on rollers 14 within the guides 9 and formed with a projection 16 adapted to take between brackets 17, 18 on the door 5 of the skip 1. The carriage 13 is raised and lowered to open and close the door by a double-acting, pneumatic ram 11. A shoot 19 for bridging the gap between the skip I and a receiving hopper 2 is carried by the guides 9. The single projection 16 of Fig. 1 may be replaced by a number of dogs 28, Fig. 4, mounted on the carriage for pivotal movement limited by stops 29 ,and adapted for engagement with a single bracket 27 on the door 5 of the skip. In an alternative construction, Fig. 3 (not shown), the door of the skip is opened and closed by an electromagnet carried by the carriage 13. The controls for the rams 11 and 21 and for the electromagnet may be interlocked with each other; with the winding gear, and with the controls for a ram 25 by which the receiving hopper 2 is opened. The pneumatic rams may be operated by compressed air or suction or may be replaced by hydraulic rams or by electricallypowered mechanism. Means may be provided for automatically withdrawing the guides 9 to provide a free passage for the skip should the power for energizing the door operating mechanism fail. The guides for the door of the skip may be disposed to press the door, when closed, against its seating.
