396,902. Buffers for railway vehicles. MITCHELL, R., 69, Kenilworth Court, Putney, London, FINLAY, W., 24, Mansionhouse Road, DOUGAL, D. and DOUGAL, A., 18, Hill Street, both in Edinburgh, (Representatives of MITCHELL, J.), and COSSEY, J. C. G., Calbourne, The Vale, Golders Green, London. May 31, 1932, No. 15450. [Class 103 (v).] In a buffer for railway and like vehicles the buffer head b is provided with an integral or attached rear extension b<1> adapted to slide on an intermediate thrust-transmitting member a, which in turn slides on the inside or outside of the buffer casing g, springs e, c being arranged within the casing and between the buffer head and end a<1> of the member a, and being adapted respectively to take the ordinary shocks and the ultimate or larger shocks. Ejection of the buffer head and member a from the casing is prevented in the usual way by a spindle f fitted at the rear of the headstock h with a recoil spring o, the spindle in the construction shown in Fig. 1 being integral with the buffer head, while the extension b<1> is separate from but riveted to the buffer head. In this arrangement the spring e is compressed first until the end a<1> contacts with the forward edge of the casing g, after which only the spring c is compressed. In a modification, Fig. 2, the head J<1> of the spindle f is flexibly connected to the buffer head, the extension b<1> is integral with the buffer head, and a washer k bearing on the spring e has an extension sleeve k<1> passing through the end a<1> and spring c to the bufferhead. In this construction, the spring e only is compressed at first, while, after the end a<1> contacts with the casing g, both springs c and e are compressed in parallel. Other modifications, with the springs functioning as in this last arrangement, are described, in which movement of the member a ceases when its rear end contacts with a shoulder on the casing g, in which the spindle head f<1> engages a cylindrical rearward extension of the buffer head, and in which the member a slides within instead of on the casing g.
