LOUIS 1VI. DILGER, 0F CANTON, OHIO.

Specification of Letters Patent.

Patented Feb. 27, 1912.

Application filed October 9, 1911. Serial No. 653,648.

To all whom it may concern:

Be it known that I, LOUIS M. DILGER, citizen of the United States, residing at Canton, in the county of Stark and State of Ohio, have invented certain new and use ful Improvements in Rail-Joints, of which the following is a specification.

This invention has for its primary object a durable and eflicient construction of rail joint whereby a practically continuous tread surface will be produced in the rails, and whereby the rails will be securely held together and properly supported at the joints, the parts being few in number and of simple construction and capable of being applied to and detached from the rails.

With these and other objects in view the invention consists in certain construction and arrangements of parts as I will hereinafter fully describe and claim.

F or a full understanding of the invention, reference is to be had to the following description and accompanying drawings, in which:

Figure 1 is a perspective view of my improved rail joint looking at the outer side of the rails. Fig. 2 is a transverse sectional View, the section being taken substantially on the line 2-2 of Fig. 1. Fig. 3 is a perspective view looking at. the inner side of the rails and Fig. 4 is a detail perspective view of one of the angle bars.

In carrying out my invention the ball or tread surface of the rails is cut away or re cessed on the outer side of the joint, as indicated at 1, the ends of the recess terminating back from the oint on both sides thereof any desired distance. This cut away portion or recess 1 is filled in by the rounded upper edge 2 of an angle bar 3, said angle bar extending along the outer side of the rails, any desired distance beyond both ends of the recess 1 and fitting against the web and base flange of the rails, as best illustrated in Fig. 1. 'On the inner side of the rails is an angle bar 4 corresponding substantially in shape and preferably in size to the bar 3 except that the angle bar 4: is devoid of the rounded upper edge 2, the angle bar 4 having its upper edge terminating close up underneath the balls of the rails, as shown.

The two angle bars 3 and 4 are recessed in their base flanges as indicated at 5, each angle bar being formed with two recesses, as shown, the recess of one angle bar being in transverse alinement with the correspond ing recess of the other angle bar. Chairs 6, two in number in the present instance extend transversely underneath the rails on opposite sides of the joint and extend upwardly on the outer sides of the angle bars 3 and 4: and are received in the recesses 5 and the registering recesses 7 that are formed in the base flanges of the rails. On the inner sides of the rails, the clamping arms 8 of the chairs 6 abut firmly against the angle bar 4 and preferably extend snugly up underneath the ball or head of the rails, while, on the outer side of the rails the clamping arms 8 are initially spaced somewhat from the adjoining angle bar 5 and wedges 9 two in number are driven in between the last named clamping arms and the web portion of the angle bar 3. These wedges are driven inwardly from the outer or non opposing sides of the chair and are formed on their outer faces at the adjoining or opposing ends with notches 10 in which the relatively free ends of a spring detent 11 are designed to snap so as to hold the wedges securely in place. In the present embodiment of the invention the spring detent 11 is composed of a fiat spring secured intermediate of its ends to a bolt 12 that extends transversely through the web portions of the angle bars 3 and 4 and through the interposed portions of the rails, this bolt serving not only to hold the spring in place but also constituting an additional means for holding the parts together.

From the foregoing description in connection with the drawings, it will be understood that after the angle bars and chair have been assembled, as shown, the wedges 9 will be driven into place, the spring 11 snapping into the notches 10 and securely holding the wedges from accidental displacement. Whenever it is desired to disconnect the parts for the purpose of repair or the like, it is only necessary to pry out the ends of the spring 11 from the wedges and to drive the wedges outwardly, whereupon the parts may be readily dis-assembled.

While the accompanying drawing discloses what I believe to be the preferred embodiment of my invention, yet it is to be understood that the invention is not limited thereto, but that various changes may be made in the construction, arrangements and proportions of the parts without departing from the scope of the invention as defined in the appended claims.

Having thus described the invention, what is claimed as new is:

1. The combination with the adjoining ends of rails, of angle bars applied to the opposite sides of the rails at the joint, the base flanges of the angle bars and rails being formed with recesses, chairs extending transversely underneath the rails and formed with clamping arms extending upwardly through the said recesses on opposite sides of the webs of the angle bars, wedges interposed between one set of clamping arms and the adjoining side of the adjacent angle bar, and means engaging said wedges for preventing the accidental withdrawal thereof.

2. The combination with the adjoining ends of rails, of angle bars applied to the opposite sides of the rails at the joint, the base flanges of the angle bars and rails being formed with recesses, chairs extending underneath the rails and formed with clamping arms projecting upwardly through said recesses, one pair of arms abutting against the web portion of one of the angle bars, wedges interposed between the other set of clamping arms and the other angle bar, the wedges being formed on their outer faces with notches, a bolt passing transversely through the angle bars and the interposed portion of the rails, and a locking spring secured on said pawl and adapted to snap into the notches of the wedges.

3. The combination with the adjoining ends out rails, the same being recessed on one side, of angle bars applied to the rails at the opposite sides thereof, one of said angle bars being formed with a rounded upper edge filling the recess of the rails, the base flanges of the angle bars and rails being formed with recesses, chairs extending underneath the rails and formed with clamping arms extending up through said recesses, one set of arms engaging one angle bar, wedges interposed between the other set of clamping bars and the adjoining angle bar, the wedges being formed in their outer faces with notches and a spring secured to the last named angle bar and adapted to spring into said notches, whereby to hold the wedges in place.

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

LOUIS M. DILGER. a 8.
