660,996. Marshalling vehicles; tipplers; elevated railways. ROSS, W. April 27, 1949. [May 12, 1948] No. 12991/48. Classes 78 (iv) and 104 (ii). A system for moving rolling stock from one station to another, via an intermediate station where the rolling stock is tippled or otherwise treated, includes a downwardly indined road between the intermediate station and the second mentioned station, controlled bogie means moving upon separate rails between or below the said road to engage and control the descent of the rolling stock and means for removing the control so that the rolling stock descends the lower part of the road freely under gravity. The system shown is for moving railway wagons to and from a tippler k and comprises an upwardly inclined track to the tippler, a downwardly inclined track c from the tippler, and cable-operated bogies a, g running on a narrow gauge track between the rails and serving respectively to raise and lower the wagons. The bogies a, g may be as described in Specification 533,794 which is referred to. The bogie a is raised by a cable a<SP>1</SP> passing over a head sheave l to a hoist drum b and is secured also to a tail rope a<SP>2</SP> which passes around a sheave at the lower end of the approach slope and round tensioning means m to the hoist drum b. As a wagon propelled by the bogie a approaches the tippler it pushes onto the tippler a loaded wagon previously hauled up and so pushes off the tippler a wagon which has been tipped. The bogie a is then lowered again, the track being graded so that the wagon last hauled up follows the bogie to a short distance away from the tippler and then stops. The wagon which has been pushed off the tippler engages the bogie g which is controlled by cables g<SP>1</SP> and g<SP>2</SP> wound on a further winch h, to rise and fall with the bogie a. The unloaded wagon travels down the slope c under the control of the bogie g, until at a predetermined point it is automatically released to fall by gravity. It then travels along a horizontal track d, rises up a slope e, and returns by gravity to be diverted from the track d to a track f leading back to a position adjacent its starting point. The unloaded wagon may be released from the bogie g, after the which h has rotated to pay out a predetermined length of the cable g<SP>1</SP>, by means on the bogie g operated when a sheave n is moved on an eccentric mounting to transfer the load in the cable g<SP>1</SP> to a further cable (not shown). The position at which the wagon is released may be varied, and the series of operations may be caused to take place automatically in synchronism with the tippler.
