Abstract
343,934. Permanent way. TURTON, PLATTS & CO., Ltd., G., Meadow Hall Road Works, Wincobank, Sheffield, and HEWITT, F., Green Lawn, Green Lane, Dronfield, near Sheffield. Nov. 25, 1929, No. 36088. [Class 104 (ii).] Chair keys are secured by a wedge permanently attached to the key and slidable therewith. The wedge may be secured in place during or after manufacture. In Figs. 1 and 2, the key has loops b and a central bend a, the ends c of the key forming a taper space for a wedge e having its ends bent down or enlarged after insertion between the ends c. The wedge may be formed by a bar g, Fig. 11, welded or riveted to the main bar so as to form a slot f embracing the bend a, or a bar may be doubled and welded at its ends. Fig. 13 shows a wedge engaging the folds in the centre, the outer loops being shortened. The key may have central portions h, Fig. 16, engaging over the wedge.
