Abstract

9815. Williams, L. W., and Walker, W. May 6. Points and switches, railway. Relates to selfreversing two-way switch levers and retaining- devices, by which the point tongues are normally retained in either of their two set positions, and are reversed automatically by the vehicle wheels when trailed through. The ground lever 1, Fig. 1, is mounted on a pin 2 and engages the forked or slotted end of one arm 6 of a bell-crank lever mounted on a vertical pin, the other arm 7 of which is connected to one of the point tie-rods 11. Fig. 6 shows the plan of a modified construction of ground lever, in which the bell-crank lever is replaced by a slotted lever 28, pivoted at 29. A projecting lug 13 of V-shape is formed on the underside of the tie-rod 11 so as to engage a grooved roller 14 mounted in a bracket 16, supported either by a sleeper or suitable rigid bar 17, or by a bar of spring steel or suitable material which will allow a small amount of yield. The interaction of the lug 13 and pulley ensures that the tongue comes to rest in one of its two extreme positions and causes the reversal of the points when trailed through. Figs. 4 and 5 show modified arrangements of the retaining - device. Specification No. 14,426, A.D. 1906, is referred to.
