A rail vehicle propulsion system comprises a pair of endless chains 3, Fig. 1, driven together by sprockets 4, on vertical axes, from a common motor (not shown) and tensioned by sprockets 5, on vertical axes, and slidably adjustable blocks 13, the operative runs 2 of the chains being parallel and disposed in gaps in the fixed rail track 10 so as to form moving rails for propelling vehicles therealong, whilst the return runs 12 of the chains are arranged alongside the runs 2. The chains are guided in guides 21, Fig. 2, of a guideway 6 mounted on a support plate 22. Each chain 3 comprises upper and lower links connected by vertical pivot pins 17, upper stepped links 16 alternating with upper flat links 15 whilst all lower links 15 are flat links. The upper surfaces of the upper links 15, 16 whose ends are curved, constitute a flat surface to receive the vehicle wheels thereon. Alternate lower links 15 carry depending webs 24 for roller pairs 23 below the pins 17. The rollers 23 engage the plate 22. Between the upper and lower links 15, 16 rollers 20 are mounted on the pins 17 to engage the guides 21.

[Also in Division B7] In a load-handling machine wherein the front wheels 3 may be extended and a pair of wheels 3 may be inturned for slewing movement of the machine, the wheel mountings 12 are linked by arms 15 and links 16 to a movable member 17 co-operating with a stop 22 which is adjustable in accordance with the degree of extension of the wheels to permit corresponding variation in the extent of movement of the movable member 17, and hence of inturning movement of the wheels. The front axle 2 is slidable relative to a rear chassis frame 7 and extends by means of a link 10 and an hydraulic ram 11 in accordance with the degree of luffing of the jib 1, as described in Specification 1,015,762, or as in copending Application 52415/67, both of which are referred to. Wheel inturning is performed by double-acting hydraulic rams 20, which turn the movable member 17 as far as permitted by the stop 22, which is a projection on a lever 24 pivoted, with the member 17, at point 19. The lever is turned, and the stop therefore adjusted, by movement of a follower 25 at its rear end in a slot 26 in a plate 27 attached to the rear chassis frame 7, as the front axle 2 bearing the pivot 19 is extended. The machine may turn about a lowerable turntable 5.

A storage bunker 1 is mounted on carriages 31 for movement by hydraulic or electric drives, or by crawler tracks, along rails 35 on either side of an outgoing conveyer 2. A delivery conveyer 4 can deliver material direct to the conveyer 2 over deflector plates 6 and through an outlet 5. If material builds up on the conveyer 2 it is moved into the bunker 1 by a conveyer 11 comprising spaced flights 12 secured to chains 13 passing round sprockets 15, 16 and driven by a pair of hydraulic rams 22 which engage the flights 12 through a catch and are arranged when stopped to position a gap over the outlet 5. A second pair of rams 22 may be provided to give a less intermittent drive. When the material build up has been cleared the stored material may be returned to the conveyer 2 through a further outlet 9 or through the outlet 5 by reversing the conveyer 11. A tensioning device for the chains 13 comprises pivoted arms 17 actuated by rams 18.

    • 1,080,021. Locking the wheels of a mine car. SHAW, TREW & SMITH Ltd., and D. G. SHAW. April 14, 1964 [Jan. 15, 1963], No. 1756/63. Heading B8E. The wheels 4 of a mine car are engaged and checked by levers 1 which engage in pairs upon and between each lateral pair of wheels 4. The levers 1 are pivotally carried at 6 by slides 9 which slide on shaft 11 positioned beneath the rails 3 on which the wheels 4 move. Sleeves 9 carry pins 15 which move in cam grooves 13 formed in element 12, and the latter is adapted to be pushed in the direction of the shaft 14 by a fluid cylinder. Each pair of arms 1 is connected by cross straps 5. Operation.-Shaft 14 is displaced axially so that element 12 moves in the direction towards spring 17. This movement causes, by engagement of pins 15 in diverging cam grooves 13, the slides 10 to move apart and thus to force the arms 1 in pairs away from engagement with the wheels 4 into the dotted line positions. When shaft 14 and element 12 are displaced in the opposite direction, pins 15 converge and arms 1 are moved into their wheel-engaging positions, as shown full line. Arms 1 are inclined in the vertical plane to assist their action.

    • 1,068,461. Conveyers. SHAW, TREW & SMITH Ltd., and D. G. SHAW. Jan. 10, 1964 [Oct. 11, 1962], No. 38496/62. Heading B7L. Control mechanism for a mine car creeper 4 is tripped by the approach of a car 3 to cause the creeper to be driven to effect a backshunt of the car. As a car 3 approaches a buffer 15 a dummy axle 30 or other part contacts a trip member 29 which forces a cam plate 25 rearwards so that the follower pin 21 is moved from a neutral position shown in Fig. 1 to cause the control valve of an hydraulic motor 16 to drive the creeper 4 forwards so that its pusher 2 produces a backshunt of the car 3. As the trolley 1 of the creeper approaches its forwardmost position during backshunting, the pusher member 2 contacts a cross-piece 34 of rods 31 connected to a rear cam-plate 26 which is thus moved forwards with the cam-plate 25 moving the pin 21 through the neutral position to a position to cause the control valve to effect reverse drive of the trolley 1. As the trolley then approaches its rear position it contacts a lug 36 connected only to the cam-plate 26 which is thus moved rearwards to position the pin 21 in its initial neutral position ready for the approach of another mine car 3.
