RAILWAY-SWITCH FASTENING.

SPECIFICATION forming part of Letters Patent No. 480,320, dated August 9, 1892.

Application filed December 14, 1891. Serial No. 415,051. (No model.)

To all whom it may concern.-

Be it known that I, SAMUEL H. (JORSON, a citizen of the United States, residing at Cape May, in the county of Cape May and State of New J ersey. have invented a new and useful Railway-Switch Fastener, of which the following is a specification. I

My invention consists in a railway-switch fastening which is carried and guided by the bottom flange of a rail into engagement with the free end of a switch-bar and by clamping it against the rail prevents the flanges of the rolling-stock wheels from opening and separating the switch-bar from the rail and the consequent derailment.

On reference to the accompanying sheet of drawings, making part of this specification, Figure 1 is a plan view of a railway main line and side track, showing the free end of the switch braced and clamped together by my invention. Fig. 2 is an enlarged perspective View of a railway-switch and rail braced and clamped together by my invention, and Fig. 3 is an enlarged perspective view of the lateral brace and clamp which I use in this instance for the purpose of illustration.

Similar letters refer to similar parts in the several views.

A A are the rails of the main track, andB B those of the side track, which are adapted to be connected with the main rails by a switch 0, pivoted at a and shown in Fig. 1 in alignment with said main rails.

D is a rock-shaft adjacent to the main track, which is operated by a weighted knockdown lever E. It is carried in suitable bearings and provided with a crank F, connecting by a rod G with a lateral brace or switch end clamp H, which is carried and guided by the bottom flange 1) of the main rail A into engagement with the free end of the switch 0.

The brace or clamp H is shown, Figs. 2 and 3, in the form of the usual rail-chair, having alongitudinal bearing 0 for the rail-flange Z) and a similar one d between the turned edges 9 for the rail-web f, allowing sufficient width for the free end g of the switch 0. Said slot or bearing (Z can be wedge-shaped or tapering longitudinally, so that but a slight motion of the clamp will serve to bind or release the switch end.

In practice the switch C is adjusted by switch mechanism (not shown) against the rail A. The vibration of the lever E, communicated to the rock-shaft D, crank F, and rod G, moves the clamp H along the bottom flange b of the rail A until its slot (1 embraces the free end g of the switch and holds it in intimate contact with said rail A, by which the opening of the switch by the flanges of the rolling-stock wheels and derailment is rendered impossible. WVhen the lever E is reversed, the clamp H is moved out of contact with the switch and the switch-moving mechanism left free for opening said switch for side railing.

I claim-- The combination, with a main-line and switch rail, of a reciprocating-clamp which is slotted for embracing and sliding over the main-line rail bottom flange and web, and actuating means whereby said clamp clasps the main-line rail and switch free end and binds them in intimate contact, for the purpose shown and described.

In testimony whereof I affix my signature in presence of two witnesses.
