RAILWAY-CROSSING STRUCTURE.

SPECIFICATION forming part of Letters Patent No. 786,193, dated March 28, 1905.

Application filed December 21, 1904. Serial No. 237,808.

To all whom if may concern.-

Be it known that I, WARNER B. CooKE, a citizen of the United States, residing at J enkintown, Pennsylvania, have invented oer-- tain Improvements in Railway-Crossing Structures, of which the following is a specification.

The object of my invention is to provide a railroad-crossing structure of great strength and durability, as fully described hereinafter, reference being had to the accompanying drawings, in which Figure 1 is a plan view of my improved railroad-crossing. Fig. 2 is a transverse section on the line 2 2, Fig. 1. Fig. 3 is a detached view of one of the intersection body portions of Fig. 1. Fig. 4 is a view of a modication of my invention:

A A, Fig. 1, are the intersection body portions of the crossing, preferably of manganese steel or other hard metal. Each body portion has an arm a, to which is attached a track-rail B, an arm a, to which is attached a track-rail O, and two extended arms a and a which abut the extended arms of other intersection body portions A, as clearly illustrated in Fig. 1, which illustrates a single track crossing a single track. Each intersection portion A is grooved at e and e to allow for the passage of the flanges of the carwheels, the groove 6 crossing the groove 6 at the proper angle.

The arms a a are in alinement with the tread-surface of the rails B B, while the arms a a are in alinement with the tread surface of the rails C O, and in order to provide a continuous surface for the tread of the car Wheels the body portions A A are recessed on the outer side of the arms a and a and bridge-rails D D are mounted in said recesses and secured to the outer side of said arms, as shown in Fig. 1. The outer portion of the tread of the car-wheels runs u on the bridgerail D, and in this way the oint between the abutting arms has no effect Whatever upon the smooth passage of the wheels. The bridgerail D in addition to this function greatly strengthens the structure at the joint between the arms. I

A guard-rail F runs parallel with the arms a and is secured thereto, being separated from the arms by suitable filler-blocks or otherwise, thus forming the groove for the car-wheel flanges. The guard-rail F likewise spans the joint between the two arms, and thus it also adds greatly to the strength of the crossing. On the outer ends of the crossing structure are guard-rail sections F, which are in line with the guard-rails F.

The bridge-rails and guard-rails may be attached to the intersection body portions by bolts or any other suitable devices, and. the structure may be supported on bedplates or other foundations without departing from the main features of my invention.

In the cross-section shown in Fig. 2 I have illustrated a filler-piece G, forming the base of the groove between the arms and the guard-rail F but this may form a part of the intersection body portion or a part of the guard-rail, as desired.

In Fig. 4 I have illustrated a modification of the invention, in which the arms a of the intersection body portions A are recessed on the inner side for the reception of the bridgerail D.

The bridge-rails in both forms of the crossing shown may be made of manganese steel or other hard metal, if desired.

I claim as my invention 1. The combination in a railroad-crossing, of two intersection body portions, each having intersecting grooves for the wheel-flanges and each having an arm, the said arms, when the portions are in place, abutting one an other, with a bridge-rail running parallel with the said arms and bridging the joint between the arms, the arms and bridge-rail together forming a continuous bearing-surface or the tread of the car-wheels, substantially as described.

2. The combination in a railroad-crossing,

of two intersection body portions, each having intersecting grooves for the wheel-flanges and each having an arm forming a continual bridge-rail mounted at one side of said arms tion of a track-rail, and the arms of the two portions abutting each other, with a bridgerail secured at one side of the said arms and bridging the oint between the arms, substantially as described.

3. The combination in a railroad-crossing, of two intersection body portions, each having intersecting grooves for the wheel-flanges and each having an arm forming a continuation of a track-rail, the said arms abutting each other, a bridge-rail secured at one side of the said arms and bridging the joint be tween the arms, with a guard-rail situated on the inner side of the two arms, substantially as described.

4. The combination in a railroad-crossing, of two intersection body portions, each having intersecting grooves for the wheel-flanges, and each intersection portion having two arms abutting arms of other intersection portions of the crossing, with bridge-rails secured to the arms and bridging the oints between the arms, the arms and bridge-rail together forming a continuous bearing-surface for the tread of the car-wheels, substantially as described.

5. The combination. in a railroad-crossing, of two intersection body portions, each having intersecting grooves for the wheel-flanges and each body portion having an arm abutting the arm of the other body portion, a

and bridging the joint between the arms, a guard-rail mounted on the inner side of the arms, and means for securing the parts together, substantially as described.

6. The combination in a railroad-crossing, of two intersection body portions, each body portion having an arm abutting the arm of the other body portion, a bridge-rail mounted at one side of said arms and bridging the joint between the arms, a guard-rail extending across the joint between the arms, and means for securing the parts together, substantially as described.

7. The combination in a railroad-crossing, of two intersection body portions of manganese steel or other hard metal, eachbody por* tion having an arm abutting the arm of the other body portion, a bridge-rail mounted at one side of said arms and bridging the joint between the arms, a guard-rail extending across the joint between the arms, and means for securing the parts together, substantially as described.

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