857,790. Feeding rail vehicles to and from tipplers and the like; moving railway vehicles; rail vehicle stops. SIMON-CARVES Ltd. Dec. 29, 1958 [Oct. 16, 1957], No. 32308/57. Classes 78 (4) and 104 (2). In a tippler installation of the kind in which mine cars coupled together by rotary couplings are each, in turn, rotated by the tippler without uncoupling the cars from the train, means are provided to positively locate the cars adjacent the entrance and exit of a tippler 1 during rotation of the car or cars in the tippler. A catch 42 and a pivoted catch 43, on the exit side of a tippler 1 (Fig. 2), are moved along a rail 30 by means of an hydraulic ram 40, the rail 30 being raised on links 31, 32 by a ram 35 to bring the catches into the path of a dummy axle 10 on a car. Similarly, on the entrance side of the tippler, a catch 52 is moved by a ram 50 along a rail 47 which is raised by means of a ram 53, and a fixed pivoted stop 25 is mounted on the mine car rails. The rams 35, 40, 50, 53 and a ram 13 for pushing the cars through the tippler may be operated manually or automatically through electrically controlled fluid valves. As the tippler reaches its car receiving position it closes a switch 90 which moves valves 62, 68, 82, 84a to the positions shown in Fig. 2 in which fluid pressure is applied to the right-hand end of ram 13, from the main variable stroke pump 60 controlled through valve 68 by pressure from a constant pressure pump 65, and pressure from the pump 65 extends the rams 35, 53 and retracts rams 40, 50 to lower the rails 30, 47 and to move the catches 42, 52 to the right. On opening of a switch 103 by movement of a carrier 19 attached to the piston of ram 13 and provided with an axle-engaging arm 23, the circuit to valve 84a is opened allowing fluid to pass from the pump 65 to retract rams 35, 53 to raise the catches 42, 52. On further movement, the carrier 19 opens a switch 104 which de-energizes valve 68 cuts off the pressure from pump 65 to control mechanism 69 to move pump 60 to an idling condition, and on opening of switch 105, pressure from pump 65 is applied to the right-hand end of ram 40, holding the catch 42 against stop 24, and to the left-hand end of ram 50 to draw the dummy axle engaging catch 52 back against the stop 25. Movement of the tippler and actuation of the switch 90 may be controlled by gamma-ray devices. For multi-car tipplers, an additional ram 13 is provided for each additional car in the tippler, the rams being connected in series.
