Application filed June 23, 1914. Serial No. 846,788.

To all whom it may concern:

Be it known that I, -WILLIAM M. GLoT- FELTY, a citizen of the United States, and a resident of Ohiopyle, in the county of Fayette and State of Pennsylvania, have invented an Improvement in Rail-Joints, of which the following is a specification;

My present invention relates to rail joints, and among other objects, it is the primary purpose of the invention to provide such a joint as will bring 'abouta practically continuous rail which will relieve the rolling stock from all shocks, jolts, and jars, in passing thereoverand which will operate with equal facilityin connection with either the standard car wheel now in use or a specially constructed car wheel which I prefer in time to introduce. I

A further object of my invention is to provide a practical appliance of this character which will form a. compact joint including parts which effectively brace the rail at'both sides and the bracing action of which will be increased rather than diminished under strain in use.

- Further objects and the advantages arising and resulting therefrom will plainly appear in the course of the following descriptioninwhich reference is made .to the accompanying drawings, forming a part of thls specification, and illustrating my invention, and in which- Figure 1 1s a plan view of a rail joint formed in accordance with my invention. Fig. 2 is a side elevation thereof. Fig. 3 is a detail perspective view of one of the tie plates removed. Fig. 4 is an enlarged transverse section taken through the joint at a point substantially on line M of Fig. l. and showing a peripheral portion of an improved car wheel particularly desirable for use in connection therewith. Fig. 5 is a similar view of the upper portion of Fig. 4: showing a peripheral portion of the standard car wheel, and Fig. 6 is a detail perspective view of the inside bar of the joint.

- Referring now to these figures, and particularly to Figs. 1 and 2, it will be seen that I provide for the connection of the ends of rails A and B at points between ties G and D, the joint itself being formed by side bars E and F extending respectively along the outer and inner sides of the rail ends and which are bolted together therethrough, together with tie plates G associated on the ties G and D and of a structure cooperating Specification of Letters'Yatent. t t d jet; 20, 1 1;

with the particular constructionof theconj necting' bars E and F in the manner to be hereinafter particularly brought out. i

Each'of' the tie platesG, one of which is shown in detail in Fig. 3, is provided 4 with a central transverse groove 9 forming the seat; for the base of'the respective rails v A, B and has, along the inner edge of the groove g, an overhanging lip 9 adapted to overlie the inner edge of the rail base as clearly shown inFig. 4; Upon the outer side of its groove 9, the upper surface of theplate is'cut away to provide an inclined sur face" 9 to aline with the upper surface of the outside portion of the rail base as also 1 particularly seen in Fig. 4, this inclined face 9 terminating in a' shoulder-g against.

which the outer edge of the outwardly extended-base flange eofthe outer joint bar E abuts. The outer joint bar E thus has its base 6 seated partially on the base flange of the rail and partially on the inclined surface g -of each of the tie plates G, and, at points adjacent the tieplates is confined between I theweb of the rail and the tie plateshouL der 9 so as to firmly brace thesame in connection with the rail, in addition to the ac tion of the several transverse bolts H which extend laterally through the joint bars E and F and through the web of the rail.

The upper innerportion of the outer joint bar E is cut away so as to snugly fit beneath theouter portions of the rail heads at. e,

the outer upperportion thereofbeing extended and provided With a beveledinner face held snugly against similarly beveled faces of the rail ends formed by cutting away the rail heads along their outer sides,

these beveled faces being clearly shown in Fig. d as snugly engaging at 6 As seen clearly in the figure mentioned the outer upper portionof the outer joint bar E has its upper surface 67 extended to a point substantially flush with the upper surface of the rail heads so as to form a part of the supporting tractive surface thereof, the part of the tractive surface so formed by the upper portion of this joint bar being extended within the normal area of the rails to a point sufficient to receive and support a portion of the face ofa standard car wheel I such as shown in Fig. 5. Thelower portion or base of the inner jointbar F sits on the inner base flange of the rail and is confined between the tie plate lip gand the web ofthe rail and is further provided with i i a longitudinal. shoulder 7 which bears upon the tie plate lip ust mentioned. This inner joint bar is also provided with an inwardly extending portion 7" along its upper edge which forms a traction surface for the flange I of the standard car wheel, as best shown in Fig. 5, extending along the lower inner side of the rail head for this purpose. Thus between the inner and outer joint bars, the former of which constitutes a tractive surface for the wheel flange and the latter of which constitutes a part of the tractive surface of the rail for the wheel face, the wheel iscarried over the, joint between two, rails without shock, jolt or jar, in practically the same manner as passage over an unbroken portion of one of the rails. It is to be noted in this connection that the opposite ends 6* and f of the tractive portions of the outer and inner oint bars are curved downwardly as best seen in Figs. 1, 2 and 6. It is also to be noted that the tie-plates G are provided with apertures g and g respectively adjacent their inner and outer ends to receive spikes J and J, the latter of which also pass through slotted openings 6 in the base flange ofthe outer joint bar E. In this manner with the twojoint bars E and F securely bolted together through the web of the rail by means of the transverse bolts H and the tie plates G securely spiked to the track ties C and D, the joining rail ends are rigidly and firmly braced in a lateral direction and along angular lines from their heads to the inner and outer ends of the tie plates, forming a rigid, strong and durable joint therebetween and as before de scribed, a continuous rail as nearly as it appears to be possible. I

\Vhile the tractive portions of the inner Copies of this patent may be obtained for five cents each,

and outer joint bars are clearly useful in connection with the standard car wheels as shown in Fig. 5, they'are also particularly adaptable and useful in connection with a car wheel K as shown in Fig. a, the face of which is substantially wider than that of the standard wheel and is provided at one side.

with an extended rim K having a fiat surface to travel upon the tractive surface of the inner joint bar F and with or without a flange ]t' for engagement against the inner surface of the inner bar mentioned.

I claim:

In a rail joint, the combination with the connected ends of rails having the outer portions of their heads cut away, of tie plates forming rail seats and between which the rail ends terminate, said tie plates having outer shoulders and inner lips, the latter of which overlie theinner edges of the rail bases, inner and outer joint bars seated be tween the rail heads and bases and locked between the webs of the rails and said shoulders and lips of the tieplates upon opposite sides of the rails, said inner and outer joint bars being respectively provided with laterally and vertically projecting tractive surfaces, the former of which extends along the lower inner sides of the rail heads, and the latter of'which projects into the outer cut out portions, offthe rail ends to a point flush with the surfaces thereof, and bolts connecting the said joint bars between their upper and lower ends and extending through the webs of the rails, all substantially as and .for the purpose set forth.
