Application filed June 3, .19244. Serial No. l'117,598.\

To all whom it may' conce/m:

Be it known that I, HARVEY A. WREN, a citizen of the United States, residing at Navy Yard, in the county of Charleston and State of South Carolina, have invented certain new and useful Improvements in Rail` Joints ;r and I do hereby declare the following to be a full, clear, and exact description of the invention, such ,as will enable others skilled in the art to which it appertains to make and use the same.

The primary object of this invention is the provision of a rail joint which will practically possess the same resiliency as the rail, thereby preventing fracture at the joint which is attributable to the usual rigid nature thereof.

In accordance with the present invention, a shplate of angle formation has the intermediate portion of the upper edge of its vertical member straight and ada ted to engage beneath the heads of l adjacent rail en s, said upper edge sloping from the intermediate straight portion to the ends of the shplate.v

The invention furthermore contemplates a fishplatein which the lateral or horizontal member has its intermediate portionV upon the bottom side hollow, whereby to provide for flexing so that, as hereinbefore stated, the joint will be substantially as resilient as the body of the rail with the result that fracture is prevented. y,

Other objects and advantages will be apparent andsuggest' themselves as the nature of the invention is understood. While the drawings illustrate an embodiment of the invention it is to be understood that in adapting the same to meet different vconditions `and requirements, various changes in the'form, proportion; and minor details of construction may be resorted to without departing from the nature of the invention'. i e l Referring to the accompanying drawings forming a part of the application, v

Figure 1 is a side view of a rail joint embodying the invention,

Figure 2 is a transverse section thereof, Figure 3 is a ylongitudinal section through the base of the fishplate, and

4Figure Il is a detail view in perspective of the ishplate.

The numeral 1 designates the ends of ad* jacent rails which. are adapted to be coupled to form a rail joint. Similar or like ishplatesfare disposed uponopposite sides of the joint and overlap the rails ends to which they are bolted. Eachl of the {ishplates comprisesa vertical member 2 and a horizontal member 3, the vertical member 2 /being placed against the web portions of the rail ends l and the horizontal portion 3 overlying the lianges at one side of the rail ends and forming the face thereof. The intermediate portion 4 of the top edge of the vertical member 2 is straight and lits` snugly beneath the heads of the rail ends so as to support the joint when subject to vertical stress. Opposite end portions 5 of the top edge of the vertical member 2 slope towards the ends of the lishplate so as to provide a l'space between said end ortions 5 and the heads of the rail ends w ereby the joint is lrendered resilient so `as to have approximately the same yield as the body of the rail. A longitudinal rib 6 is disposed along the top. edge of the vertical member 2 and extends laterally therefrom to engage the web portions of the rail ends adjacent the heads thereof. It will be understood that `the rib 6 reinforces the upper edge of the member 2. The angle formed by the vertical member 2 and horizontal member 3 is strengthened by rib 7 and the outer edge ofthe horizontal member 3. has a rib 8 to stifen and reinforce said member 3 so that it may be made of suiiiciently light construe tion to yield. The intermediate portion 9 of the horizontal member 3 is hollow upon its bottom side and comes opposite the joint formed between the base flanges of the rail ends 1, thereby materially adding to the resiliency of the joint.

In practice, a rail joint embodyingthe invention has companion fishplates disposed upon opposite sides thereof and made secure by bolts 10 which passthrough registering openings formed in the web portions of the rail ends and in the vertical members 2 of thev ishplate. The horizontal members 3 of the'fishplate overlying the base flanges oftherail ends are secured to the tie 11 by and the end portions sloping outwardly in opposite directions, and the intermediate portion of the horizontalmember being holoW u on its bottom side.
