RAILWAY-CROSSING.

SPECIFICATION forming part of Letters Patent No. 651,596, dated June 12, 1900. Application filed October 2'7, 1898. Serial No. 694,695. (No model.)

To aZZ whom it n't'ay OOIZOGVTb:

Be it known that I, EDWARD B. ENTWISLE, of Johnstown, in the county of Oambria and State of Pennsylvania, have invented a new and useful Improvement in Railway-Crossings, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to railway-crossin gs, particularly to crossings where the travel over one track is considerably heavier than that over the other. In crossings of this character it is often desirable to preserve intact the rails of the track enduring the greater traffic, and this has heretofore been usually accomplished by securing castings to the opposite sides of the unbroken main rail, so that the cars of the track having the lightest traffic will ride over the casting and across the top of the main rail. These castings at their other ends have been secured by splice-bars to the rails of the crossing track. This construction is objectionable in that the casting cannot be made sufficiently hard and tough to wear well and also because the structure is heavy and composed of a number of joints. Other means have been provided for the-same class of structure; but they have lacked the stability and staunchness required of a good crossing.

The object of this invention is to provide a crossing-in which the main-track rail shall be unbroken even by a groove across its head and so constructed that the tread-surface of the crossing track may be of rolled rail throughout, even though the crossing be assembled at the place where it is to be used. I also provide a crossing which, though assembled at the track, possesses-all the strength and solidity of a shop-built crossing.

My invention broadly consists in the provision of brackets cast integral with the crossing rails and secured to the Web of the main rail, the head of the crossing rail being prefcrably in a higher plane than that of the main rail, so that the latter may receive the wheelflanges of the car which is traveling on the crossing track. The crossing rails and brackets are cast together at the shops and at the track have only to be bolted to the main rail.

In the accompanying drawings, which illustrate my device and in which like symbols indicate like parts, Figure l is a perspective view of a bracket, a crossing rail, and part of the main rail. Fig. 2 is a plan view of one of my improved crossings. Fig. 3 is a sectional view of Fig. 2 on line 3 3, and Fig. t a sectional transverse view of Fig. 2 on line 4 4.

O is the unbroken rail of the main track.

A is the crossing rail, B a bracket secured integrally thereto, and B represents that arm of the bracket which is cast to rail A. The bracket is secured to and made part of the rail by placing the end of the rail, which has previously been provided with perforations c in its web, in a mold. The molten metal will flow through the perforations c and integrally bind the bracket to the rail; I

The rail A is placed at a higher level than rail 0, so that a car-wheel may pass from the groove in rail A over rail 0 and use the head of the latter as a treadway for its flange.

The bracket B fits snugly against the web of rail 0 and is secured to the same by bolts Z) and nuts a, as shown in Fig. 8. Aportable drill may be used to drill the holes in the web of rail 0. The laterally-extending arms of the bracket are made of sufficient thickness to underlie and support the'full width of the overhanging tread portion of the head of the through-rail, thus forming a solid structure which will not hammer or break down under the action of car-Wheels. The entire wheel bearing-surface, it will be noted, is formed by rolled rails.

The crossing herein illustrated and described is especially applicable for use where a much-used cable or electric railroad is to be crossed by a horsecar or other road of light traffic, as such a construction will not impair the strength of the main rails, While the structure is as substantial and durable as a shopbuilt structure. It combines the work of the shop and the work on the track so as to obtain the advantages of each.

While I have shown and described a specific structure and suggested for it a specific use, to which it seems preferably adapted, I do not desire to limit myself to either the particular details set forth or its use with the particular type of railroads suggested, as the structure may be considerably modified without departing outside the scope of myinvention as set forth in the appended claim.

Having thus described my invention, what I claim, and desire to protect by Letters Patent, is-

In a railway-crossing, the combination with an unbroken main-line rail, of a crossing-rad end abutting the main rail, and having integral with its abutting end laterally-extending cast-metal bracket-arms of sufficient thickness to support the overhanging tread pertion of the main rail, said arms being detachably secured to the Web of said main rail, substantially as described.

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