881,345. Railway buffers. WILISCH, E., and LOTZE, B., [trading as A. RAWIE KOMM.-GES.]. Nov. 24, 1958, No. 37796/58. Class 104 (2). A movable buffer for braking and stopping railway vehicles comprises the combination of first friction members arranged underneath two rails and connected with the buffer so as to be loaded by an approaching vehicle and second friction members which are also connected to the buffers for frictional action on the track rails and which are pressed against the rails by threaded bolts and two supports extending in the longitudinal direction of the track rails. In the arrangement shown in Figs. 1, 2, 3 and 6, the buffer 2 is provided at its sides with two longitudinal channel-shaped supports 4, 5 secured to sleepers 6 laying close side by side and resting on a concrete or gravel foundation 1. The sleepers 6 are generally connected in groups of five by T-section members 29 the upper webs of which are connected to the channels 4, 5. Track rails 8 are slidably mounted by means of spikes 11 on sleepers 7 connected to the channels 4, 5 by angles 28 and above the sleepers 6. A fork 10 secured to a strut 9 in turn connected to the channels 4, 5 and to a number of sleepers 7 by angles 12 and having flanges which slide along the rails 8 is provided to enable the buffer 2 to be returned to its initial position. Plates 32 secured to the ends of the channels 4, 5 at the approach side of the buffer 2 are connected to links 13, 14, 15 connected to a draw-bar 17 secured to a sleeper 16 and provided with projections 27 which serve as guides to the track 8 with the assistance of flanges 26. The sleeper 16 is slidable beneath the rail 8 and a number of sleepers 16 interconnected by links 13, 14, 15 and draw-bar 17 may be provided. Arms 19, 20 secured to a channel member 18 interconnecting the side walls of the buffer 2, are connected to links 21, 22 in turn connected to plates 23 secured to a cross member 24. A number of such links 21, 22 and plates 23 may be provided. The arms 19, 20 consist of rail sections, Fig. 6, and are so arranged that they form together with brake body spacers 41 and flanges 25 a brake acting on the sides and downward facing surfaces of the head 48 of the rail 8. The flange 25 and the arms 19, 20 bear on a support member 42 and are clamped against the rail head 48 by a bolt 40 and nut 46. The flange 25 is provided with inwardly-turned ends, Fig. 7 (not shown), to prevent longitudinal displacement of the spacers 41. A similar arrangement of arms 19, 20, spacers 41, flanges 25, bolts and nuts 40, 46 is arranged beneath each plate 23. The buffer operates as follows. When a vehicle approaches the buffer 2 the buffer is first pushed back, together with the members 19, 20, 41 and 25 and sleepers 6. As the buffers 2 are pushed further back the links 13, 14, 15 are extended to effect further braking by pulling successive sleepers 16 along the foundation 1 and the links 21, 22 are bent inwardly to enable the arms 19, 20 to engage and push similar members arranged beneath successive plates 23. In the embodiment shown in Figs. 10, 12, the braking members, which are loaded by the weight of the approaching vehicle, are arranged behind the buffers. Rails 59, arranged outside the track rails 8, are fixed to members 60 by a number of clamps 62, 63 whereas the member 60 is permitted to slide beneath the rail track 8 by guides 61, 62. Longitudinal supports 54, of rail profile section, are attached to the side walls 50 of the buffer and form together with spacers 65 the brake members engaging the heads of the rail 8 and held in position by bolts 66, Fig. 12. Fish-plates 68, welded to the supports 54, rest with their free ends against the under-surface 69 of heads 70 of the rail 59 and fish-plates 71, mounted on the buffer side walls 50 are provided with shaped ends 71 to engage beneath the heads 70 of the rail 59 to provide a braking effect. The rails 59 are connected at their rear ends to a device consisting of two abutting members 74, 75 of which the member 74 is connected with buffer pads 76, 77 whereas the member 75 is connected with two angles 78, 79. The two members 74, 75 are connected at their ends by plates 80, 81. The track rails 8 and rails 59 rest on sleepers 82, 83 which are connected together by straps 84, 85 secured to webs 86 and members 60. The apparatus operates as follows. The approaching vehicle strikes and moves the buffer and rails 59 rearwards and the buffer is pushed against a trip device at the ends of the rails 59. Initial movement causes the members 60 arranged at the approach of the rail 59 to abut the first sleeper 82. Subsequent rearward movement of the buffer causes the member 60 to push the sleepers 82, 83 over the foundation. In a further embodiment shown in Fig. 14, the movable sleepers in contact with the foundations are arranged on the approach side of the buffer. In this arrangement longitudinal channel supports 86, 87 are connected by flanges 88, 89 to a frame 90 on which guiding flanges 91 for the rails 8 are provided. Channel members 93, 94 overlying the plate 90, are connected to sleepers 95, 96, 97 to form a sleeper unit. A second sleeper unit comprises sleepers 99, 100, with a further sleeper not shown, connected by draw bars 102, 103, 104 and 105. A further sleeper unit consists of the sleepers, the first sleeper of which is 101, connected by draw bars 106, 107, 108, 109. The device operates as follows. When the buffer is pushed back by a vehicle the braking elements 110, 111, 112 and 113 operate on the track rails 8 as previously described and at the same time the frame 90 is moved rearwardly until its rear edge 114 abuts the sleeper 95 to move the first sleeper unit 95, 96 and 97. Further rearward movement causes the second and subsequently the third sleeper units to be moved. In yet a further embodiment shown in Figs. 16, 17 and 18 the approach ends of the channel supports 119, 120 are rigidly connected to plates 123 connected to a spacing member 124 arranged beneath the track 8 and carrying guide flanges 125, 126 for the track rail 8. Members 127 attached to the plates 123 extend alongside the track rails 8 and are connected to sleepers 128, 129 which are of such a height that friction contact is made with the foundation after rearward movement of the buffer. The track rails 8 are suspended in brackets 130, 131 supported on beams 132 embedded in the concrete foundation.
