RAIL-LOOKING DEVICE,

To all whom it may concern."

Be'it known that I, CHARLES P. WALKER,

a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to'make and use the same. j

This invention relates to a] rail locking device. 7

An. object of the invention resides in the provision of a device by means of which rails may be securely locked in place upon a tie. v

A further object of the invention resides in so constructing the Cl6"l(36 that the meet ing ends of two rails may be secured in place without the use of fish-plates and bolts.

7 lVith these and other objects in view, such as will appear as the description progresses, my invention comprises the combination and arrangement of parts as set forth in and falling within the scope of the appended claims.

Referring to the drawing: Figure 1 is a side elevation of my device, showing the parts in their locking positions and showing a rail in place thereon. Fig. 2 is a plan view thereof, showing the meeting ends of two rails thereon. Fig. 3 is an end elevation of the same. Fig. 1 is a longitudinal sectional view. Fig. 5 is a fragmental detail, showing one of the locking members in its operative position and the other of the locking members in its inoperative position.

Fig. 6 is a fragmental detail showing the manner of securing the locking members to the clamping plates.

Referring to the drawing wherein like parts are indicated by like characters throughout the several views :-In the embodiment of my invention shown in the drawing, I have provided a metallic base plate 1 having notches 2 in the ends thereof which are adapted to engage suitable spikes '3 upon the cross tie 4. The heads of these spikes extend upwardly beyond the upper face of the base plate 1, as illustrated in the drawing. Extending transversely of this base plate 1 are spaced integral ribs 5 between which the ends of the rails 6 are positioned. Formed on the opposite edges of Specification of Letters Patent. Patented Dec, 21, 1915. Application filed June 9 1915. Serial No. 33,108.

the'platel and extending upwardly are integral ears 7, one pair being located to each side of the rail. Mounted in these ears and extending transversely across the plate 1 are rods '8 which are slightly spaced from the upper face of the plate 1, as illustrated in the drawing. I V

Extending beneath the rods 8 are clamping plates 9 madepreferably of spring metal and having openings 10 at the ends thereof adapted to engage the heads of the spikes 3. The opposite ends of these clamping plates 9 are bent upwardly, as indicated at 11, so as to fit over the base of the rail and to bear against the web thereof. The disspikes 3 at each side is slightly less than the distance between the rail engaging end of the plate and the point where it engages the spikes. Thus when the plats are forced down into engagement with the base plate 1 the rail will be clamped therebetween.

In order that the clamping plates 9 may be forced into engagement with the base plate 1, I have provided locking plates 12 which have channels 13 therein in which the rods 8 are located. These locking plates are provided with cam surfaces 1 1 so that when the plates are rotated about the rods 8 as pivots the cam faces will ride upon the upper faces of the clamping plates 9 and force them into position upon the base plate 1. These locking plates 12 are provided withinclined portions 15 which lie upon the upper faces of the portions 11 of the clamping plates 9. In order that the clamping plates and locking plates may be secured together, I have provided a plurality of staples 16 upon the inner edges of the clamping plates which extend through apertures 17 in the adjacent edges of the locking plates 12. A wire key 18 extends through the staples l6 and the ends thereof are secured together so that the displacement of the locking plates will be prevented. The inner edges of the locking plates 12 are upturned to form flanges 1.9 for engagement by suitable tools so that they may be drawn over the staples on the clamping plates. When the abutting ends of two rails are secured together in this manner they will be prevented from lateral movement or otherwise being displaced.

In assembling the device the base plate 1 is secured to the cross tie by the spikes 3 and the ends of the spikes project above the 7 plane of the upper face of the plate 1. The

I ra T clamping plates 9 the rails are then placed upon the base plate with the plates 9 beneath the rods 8. The lockingplates 12 are then placed upon the rods 8 in the manner shown in Fig. 5 of the drawing. These plates are then swung into position as also illustrated in this figure so that they will then passed throughthe staples and the ends secured together. The ends of the rail will thus be firmly clamped into position and locked into such position.

While I have illustrated and described a particular embodiment ofmy invention, I

, Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents,

have merely done so for the sake of convenience and I do not wish to be limited to that particular embodiment as it is obvious 7 that numerous changes may be made within the details of construction thereof without in any way departing from the spirit of the invention or exceeding the scope of the appended claims.

What I 01am e1 1. In a rail locking device, the combination with a base plate having ears thereon, of rods extending between said ears, clampingrv plates disposed between said rods and said base plate and locking plates pivoted on the said rods and having cam faces thereon adapted to force the clamping plates into engagement with the base plate.

2. In a rail locking device, the combination with a base plate having ears thereon, of rods extending between said ears, clamping plates mounted between said rods and said base plate and having rail engaging portions, locking plates pivotally mounted on said rods and adapted to force the clamping plates into engagement with the base plate, staples upon the said clamping plates,

the said locking plates being provided withapertures for receiving said staples, and wire keys extendlng through said staples.

In testimony whereof, I afllx my signature, in the presence of two witnesses.

CHARLES P. WALKER."
