RAIL JOINT.

Application filed August 10, 1926. Serial No. 128,4I5.

This invention relates to a joint for railway rails, one of the objects being to provide simple and efficient means for joining the rails at the meeting ends thereof without the use of ordinary fish-plates and without the use of the bolts commonly employed for holding fish-plates to the rails.

A further object is to provide a rail joint which will support the meeting ends of the rails so as to prevent the car wheels from pounding while passing over the joints.

lVith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the inventionhas been shown.

In said drawings,

Figure 1 is a front elevation of the rail joint, one of the rails engaged thereby being shown in section.

Figure 2 is a top plan View.

Figure 3 is a side elevation.

Referring to the figures by characters of reference 1 designates a base plate providing a chair for the rails R directly under the meeting ends thereof, it being understood, however, that one of these joints can also be placed wherever desired between the ends of the rails. The base plate of the chair 1 is provided with an upstanding jaw 2 designed to fit snugly under the ball or head of each rail and provided with an overhang 3 whereby the base flanges of the rails will be overlapped and the jaw can fit snugly against the rail web. Jaw 2 has depressions 4 in the top thereof adjacent the respective side faces, there being threaded bores 5 extending downwardly from the shoulders 6 provided by these recesses. These bores are adapted to receive set screws 7 and lock nuts 8 are mounted on the set screws for engagement with the shoulders 6 so as to hold the set screws against unscrewing. The set screws seated in these bores are adapted to project downwardly through the overhang 3 so as to engage the base flange of the rail as shown in Figure 1.

Base 1 has a transverse flange 9 extending upwardly therefrom and spaced from the jaw 2 a sufiicient distance to allow the base of the rail R to be lowered onto the plate 1 between aw 2 and flange 9. The rail is then adapted to be shifted laterally to bring one of its base flanges under the overhang 3 as shown in Figure 1. Flange 9 is undercut as at 10 to provide a longitudinal groove and this groove is adapted to receive a rib 11 formed along the outerside of a slidable block 12 which is insertible longitudinally between flange 9 and the rail R. Block 12 is so shaped as to fitsnugly against the web of the rails and against the underside of the head or ball of the rails and this block also has an overhang 13 adapted to lap one of the base'flanges of the rails as shown in Figure 1. Bores 14 are provided within the block for the reception of set screws 15 and each set screw has a lock nut 16 for engaging the top surface of the block whereby the set screws are held against unscrewing.

The base plate 1 extends outwardly beyond the jaw 2, this projecting portion, indicated at 17, being provided with apertures 18 for the reception of spikes or the like used for fastening the base plate to a tie. The base plate is also extended outwardly beyond the flange 9 as shown at 19, this projecting portion being formed with fastener receiving openings 20. Openings 21 are also formed in the base plate close to the flange 9 and are adapted to aline with corresponding openings 22 formed in the block 12. Thus after the block has been assembled with the rail R and base plate as described, spikes, some of which have been indicated at S, can be inserted into the openings 22 and 21 and driven into the tie supporting the plate.

It will be apparent that by providing a means such as described the rails can be securely held to the ties and to each other without using bolts extending transversely to the webs of the rails. When the set screws 7 and 15 are tightened against the base flanges of the rails they will bite into the upper surfaces of said flanges and insure proper fastening of the parts. While the set screws are being tightened against the base flange of the rail the block will be forced tightly at one side against the under surface of the head of the rail R while the other or outer side of the block will be caused to bind tightly against the adjacent portion of the flange 9.. In other words the flange and the head of the rail constituting retaining means for holding the block against upward displacement while the set screws are being forced downwardly against the base flange of the rail.

The structure constituting the present invention not only serves properly to connect the rails to each other and to a tie but they also provide efficient supports for the heads or balls of the rails so that they will not sag in use. Consequently pounding of tie wheels passing over the joints will be eliminated.

What is claimed is:

A device of the class described including a base plate, a transverse jaw thereon having an overhang for lapping the base flange of a rail bearing laterally against the jaw, a transverse flange upon the base plate, the shortest distance between the transverse jaw and the transverse flange being greater than the width of a rail, thereby to receive the rail movable if downwardly onto the plate, a block insertible longitudinally between said flange and the engaged rail, inter-fitting means upon the block and flange for holding said block at its outer side against upward displacement relative to the flange, that side of the block engagingthe rail being held against upward displacement by the head of the rail, means extending through the block and base plate for holding them assembled, and set screws eX- tending through the block for engagement with one of the base flanges of the engaged rail thereby to bind the block against the under-surface of the head of the rail and against the engaged portion of the flange, both the jaw and block constituting means for supporting the head of the rail.

In testimony that I claim the foregoing as my own, I have hereto afflxed my signature.

RICHARD WV. SCHULTZ.
