Abstract

257,677. Elliot, C. June 5, 1925. Rope railways.-Apparatus for pushing colliery tubs a into a mine cage b, and for similar purposes, comprises a one-way pusher c<2> pivotally mounted on a bogie c which runs to and fro between rails d. The bogie is normally held in the position shown in full lines by triggers e, e<1> engaging the lower end of the pusher c<2>, and the pusher acts as a stop to hold back the on-coming tubs As the cage approaches the bank, it engages a catch f, and pulls down the triggers, and the bogie c is then moved to the right by a weight g<2>, the pivoted pusher c<2> passing under the tubs and rising again behind them as shown in broken lines. The bogie is then moved forwards by a projection h' on the endless chain or belt h engaging an arm c<5>. The chain h is driven through a friction clutch h<3>, which is engaged by hand, or automatically by the bogie striking a lever h<5> to actuate the link h<6>. As the bogie approaches the end of its forward movement, wedges j on the track raise a stop on the bogie, allowing the arm c<5> to turn about a pivot and become free from driving member h<1>. The chain h runs on until the projection h<1 >strikes the lever h<5> and throws out the clutch. The bogie overruns the triggers e<1>, e, but is returned to the initial position by the action of the weight. g<2>, and is then held by the triggers.
