738,038. Railway wagon tipplers; transferring wagons into tipplers. MITCHELL, F. G. March 16, 1954 [March 17, 1953], No. 7400/53. Classes 78 (4) and 104 (2). A railway wagon tippler has mounted on carrier thereon or therein a travelling mechanism movable in a direction parallel to the carrier rails and the mechanism comprises two or more members movable in and relative to one another in the same direction parallel to the carrier rails whereby an effective travel greater than the carrier length is imparted to one member and associated with the other member are catch means provided to engage the railway wagon to be moved. The wagon tippler comprises two end frames 11 each frame 11 rolling on supporting rollers 13 the structure being rotated by a pinion 25 engaging toothed sectors 25 mounted on the frames 11. A platform 14 provided with rails 15 is rotatably mounted between the frames 11 and has mounted thereon rolls 17 which engage a ledge in a foundation pit 16 to tilt a wagon 12 when the tippler is rotated. The wagon 12 on being tilted abuts chocks 19, 20 on the tippler frame. The travelling mechanism mounted on the platform 14 comprises a main trolley 26 mounted on rails 28 and a secondary trolley 27 mounted on channel-shaped rails 35 carried by the main trolley 26. The main trolley 26 is driven by a duplicated rope drive. Each rope or cable 31 is wound at one end on a drum 30 and passes over sheaves 32 mounted on the platform and is fixed at its other end to an anchoring attachment 33 on the main trolley 26. The secondary trolley 27 is driven by a duplicated rope drive 40 and one end of each rope or cable 40 is secured to an anchorage 37 on the carrier and passes over a sheave 38 on the main trolley 26 to one end of a tension spring 39 on the secondary trolley 27. The other end of each rope or cable 40 is attached to the other end of the spring 39 and passes over a sheave 41 mounted on the main trolley 26 to the anchorage 37. An axle catch is mounted on the secondary trolley 26 and comprises a forked plate 43 vertically movable so as to engage an axle of a wagon 12. The catch is rotated to a locking position on movement of the trolley 27. In operation the main and secondary trolleys 26, 27 are moved to the chain dotted position, shown in Fig. 2, in which position the catch engages the axle of a wagon 12 and after engagement the movement of the trolleys 26, 27 is reversed to draw the wagon 12 on to the platform 14. After the tipping operation the trolleys 26, 27 are operated to move the wagon 12 to one side of the platform 14. The travelling mechanism may be arranged to move the wagon 12 on and/or off one side or on one side and off the other side of the platform 14. The track leading to the platform 14 may be downwardly sloped towards the platform 14 or the track leading away from the platform 14 may be downwardly sloped away from the platform 14. The tippler may be of the typo associated with an elevating mechanism. The rope drive for the main trolley 26 may be replaced by a rack drive.
