4 Claims. 1

This invention relates to improvements in rail fasteners, and more particularly to fasteners of the anchoring spike type.

One object of the invention is to provide a rail anchoring spike, which is self locking to efiectively hold the same clamped against the flange of the usual rail.

A more specific object of the invention is to provide a fastener for rails in the form of a spike, driven into the tie which supports the rail, extending through the usual tie plate, having the h'ead portion thereof provided with a laterally projecting arm at one side engaged over the flange of the rail to hold the rail in place, and a resilient locking finger at the opposite side having hooked shouldered engagement with the tie plate to lock the fastener against withdrawal from the tie.

Other objects of the invention will more clearly appear from the description and claims hereinafter following.

In the drawing forming a part of this specification, Figure 1 is a transverse, vertical sectional view through a rail member and an associated tie plate and railroad tie, illustrating my improvements in connection therewith, said section being taken on the line ll of Figure 2. Figure 2 is a top plan view of Figure 1, partly broken away. Figure 3 is a transverse, vertical sectional view through the rail member shown in Figure 1, said view being in a plane at one side of the tie, the tie and tie plate being shown in elevation and the spike member being shown as partly driven into the tie. Figure 4 is a view, similar to Figure 3, showing the spike member in another position. Figure 5 is a top plan view of the tie plate employed in connection with my improvements, said away.

In said drawing, I0 indicates the usual rail member and II, the supporting tie. The rail I [I is of the type commonly employed, having laterally projecting base flanges |2|2, the upper surfaces of which are inclined upwardly toward the web l3 of said rail.

In carrying out my invention, I provide broadly a tie plate A, and an anchoring spike B which clamps against the rail flange and has shouldered engagement with the tie plate to lock the same to the plate.

The tie plate A is preferably of rectangular outline and is interposed between the base of the rail l0 and the tie member I I. As shown, the plate A is provided with an elongated, rectangular opening I 4 adapted to accommodate the view being partly broken shank of the spike B. The opening I4 is located to one side of the corresponding base flange l2 of the rail ID, as clearly shown in Figure 1, and has its length arranged at right angles to the length of the rail. The wall at the end of the opening l4, remote from the rail flange, is downwardly beveled, as indicated at l5, and a relatively heavy, upstanding lug l6, formed integral with said plate, is located adjacent said end of the opening and has a laterally projecting portion I! which overhangs the opening. The portion I! of the lug l6 presents a downwardly facing, flat abutment shoulder l8, which serves as a stop for locking the spike B in position. The end face of said projecting portion is beveled oil to provide a cam face I9.

The spike B is made of spring steel material and heat treated to provide resiliency. It comprises a shank portion 29 and a driving head member 2!. The shank portion is preferably of rectangular cross section and has its lower end pointed in the usual manner to facilitate driving the same into the tie. At one side thereof, the head member 2| is provided with a laterally extending, elongated arm 22 of the shape shown, engaging over the corresponding bottom flange I2 of the rail l0. As most clearly shown in Figure l, the outer end portion of the arm 22 is downwardly thickened, as indicated at 23, said thickened portion presenting a rounded or convex underneath face which bears on the flange l2 of the rail. At the side of the spike B which is opposite the arm 22 of the head, the latter is provided with a depending locking spring finger 24, which is formed integral with said head, The locking finger is slightly oifset with respect to the shank of the spike and is inclined away from said shank in downward direction, as shown in Figures 1 and 4. The lower end of the finger 24 is formed into a hook portion 25, which is adapted to lock beneath the projecting portion I! of the lug IS. The end of the hook portion 25 is beveled oil to provide a cam face 26 adapted to cooperate with the cam face l9 of the lug N5 of the tie plate. The top of the head 2| presents the usual flat driving face 21.

When the spike B has been driven home, as shown in Figure 1, with the arm 22 clamping the flange of the rail, the hook-25 of the finger- 24 is engaged beneath the projection I! of the lug l6 of the tie plate A, thus effectively locking the spike against upward movement.

In applying my improved rail fastener, the spike B is driven into the tie through the opening M of the plate A, as clearly shown in Figure 3, by the .cam face 26 thereof riding over 5 the cam face I9 of the lug. When the spike is driven home, the hook portion 25 of the finger snaps beneaththe projection 11 of the lug [6 to lock the spike against removal.

As will be evident, the spike B being made of mu resilient locking finger on the other side of said head, said finger having a hooked portion integral spring steel, the arm 22 is sufficiently resilientto .flex slightly in upward direction, thus easing: the upward pull on the spike, due to upward pressure exerted on the clamping arm: n by th e rail flange, thereby preventing-thespikefrom 16 being loosened.
