CHESTER F. GAILOR,

OF NEW YORK, Y.

WELDED RAIL-JOINT.

T all whom it may concern:

Be it known that I, CHESTER F. GAiLoR, a citizen of the United States, residing at New York city, county of New York, and State of New York, have invented certain new and useful Improvements in \Velded Rail-Joints,

of which the following is a specification.

This invention relates to improvements in welded rail-joints particularly adapted to electric railway uses.

The objects of the invention are to secure permanent electric conductivity from one rail to another; to evenly distribute the shock of the moving car throughout the joint between two abutting rails; to over come all possibility of wear between the plates and rails; to prevent atmospheric changes from taking place between the plates and rails; to provide a form of joint which can be supported or suspended as desired to accommodate the same to various forms of paving construction; and to enable the joint to resist the forces of expansion and contraction, due to changes in temperature.

The invention consists in drawing the abutting ends of the rails into close contact with each other by bolting or riveting to the sides of the rails, splicing-plates, and afterward welding the edges of such plates to the rails, the edges on one end of each plate to one rail, andthe edges on the other end of each plate to the other rail, as will be hereinafter more fully described and subsequently pointed out in the claims.

' Referring to the drawings: Figure 1 is a view in perspective showing the completed joint. Fig. 2 represents a cross section taken through the joint at the ends of the abutting rails.

Therails are provided with the head, 1, and base, 2, united by the vertical web 3.

The splicing-plates, 4 and 5, are each provided with longitudinal edge-flanges, the upper flanges, 6, adapted to engage with the under side of the head, the lower flanges, 7, adapted to engage with the upper surface of the base. The plates are first secured to the rails, so as to lap the joint formed by the abutting ends of the rails, by means of the bolts or rivets, 9, inserted through apertures in the plates and in the web of the rails. These holes are carefully bored to register with each other, when the abutting ends of the rails are tight together. When desired, the holes are reamed while the plates are in Specification of Letters Patent.

REfssU p place, thereby insuring a perfect fit, and preventing any separation or other displacement of the joint by contraction and expansion. When desired, the rivets are driven hot, and calculated to stand all stresses due to variations of temperature and traffic. The plates are then welded to the rails around their edges. When the platesare welded throughout their upper and lower edges to the rails, the edges on one end of the plates to one rail, and the edges on the other end of the plates to the other rail, the joint is materially and sufficiently strengthened to resist all shocks and stresses which are distributed throughout the entire length of the plates, and a sufficient electric bond between the abutting rails is established.

As a means for preventing accumulation of moisture between the plates and rails, which sets up oxidation of the parts, and eventually causes them to deteriorate and become worthless, the end edges of the plates are also welded to the rails, which prevents the accumulation of moisture between the plates and rails. When desired, the edges of the abutting rails may also be welded together where they are not covered by the plates. It will be suiiicient in most cases to weld the abutting edges of the base of the rails only, between the two plates, as the base of the rails is buried, while the head of the rails is above the surface of the ground.

It is obvious that any known system of welding may be em loyed.

In using the wor s bolting or bolted in connection with the splicing-plates and rails, in the specification and claims, it is intended to include riveting or riveted, as well as any other equivalent mechanism for mechanically connecting the ends of the rails in an abutting position. By welding the side and end edges of a lapping splicing plate to the abutting rails, a maximum rigidity is secured, with a minimum heating and ex ansion of therails, and moisture is exclude from between the unwelded portions of the plate and rails.

What I claim as new and desire to secure by Letters Patent is 1. That improvement in the art of uniting rails and splicinglates, which consists in placing the rails en to end in alinement with each other, securing the rails in abutting contact by bolting a pair of lapping plates to the sides of the rails, one plate on each of the opposite sides "of the rails, and afterward welding the upper andloweredges of the lapping the sides of the rails, one plate on each of the plates to the rails.

2. That improvement in the art of uniting end-abutting rails and splicinglates, which consists in welding a la ping p ate throughout its side and end e ges to the rails, the

edges of one end to one rail, and the edges of the other endto the other rail whereby a maximum rigidity, with minimum heat expansion, is securedyand moisture excluded rom the space between the unwelded portions of the plates and rails.

3. That improvement in the art of joining end-abutting rails having a head and base united by a vertical web, with splicing-plates having longitudinal edgealanws adapted to engage respectively with the head and base of the rails, which consists in welding the edge-flanges of the plates to the base and head of the rails respectively, the edges of one end of the plate to one of the rails, and

the edges of the other end of the plate to the other rail.

4. That improvement in the art of joining end-abutting rails having a head and base united by a vertical web, with splicing-plates having lon itudinal edge-flan es adapted to engage the head and base of the rails respectively, which consists in securing the rails end to end in abutting contact with each other by bolting a pair of lapping plates to the sides of the rails, one plate on each of the opposite sides of the rails, and afterward welding the u per flanges of the plates to the under side 0 the head of each rail and the lower flanges of the plates to the upper surfaces of the rail-bases respectively.

5. That improvement in the art of joining end-abutting rails having a head and base united by a vertical web, with splicing-plates having lon'itudinal edge-flan es adapted to engage the ead and base of t e rails respectively, which consists in securing the rails end to end in abutting contact with each other by riveting a pair of lapping plates to op osite sides of the rails, and afterward we ding the up er flan es of the plates to the under side of t e hea of each rail and the lower flanges of the plates to the upper surfaces of the rail-bases respectively, and welding the end-edges of the plates to-the head, web, and base of the rails respectively.

6. That improvement in the art of uniting end-abutting rails and splicingplates, which consists in welding the upper and lower edges of a pair of splicing-plates to end-abutting rails, one plate on one side of the rails, and the other late on the op osite side of the rails, the e ges of one end 0 each plate to one rail, and the edges of the other .end of each plate to the other rail, and welding the abutting edges of the bases of the rails from the splicing-plate on one side of the rails to the splicing-plate on the other side of the rails.

7. A rail-joint comprising end-abutting rails, and a pair of splicin -plates having longitudinal edge-flanges an riveted to the rails, and welded, their. up er edge-flanges to the heads of the rails, and their lower edgeflanges to the bases of the rails.

8. A rail-joint comprising end-abutting rails, a pair of splicinglates, severally welded throughout all of t eir edges to the rails, and a welded union of the edges of the abutting bases of the rails extendin from a splicing-plate on one side of the rai s to the splicing-plate on the opposite side of the rails.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.
