Specification of Letters Patent.

Application filed July 21, 1904. Serial No. 217,460.

To ail whom it may concern:

Be it known that I, EUGENE HAYWARD, a citizen of the United States, and a resident of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Railway Frogs and Crossings; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in railway frogs and crossings, and has for its object an exceedingly strong and rigid structure adapted to afford frogs adapted for use at switches and at the angles of the crossings, so constructed as to avoid the jolting and vibration due to the truck passing over the open spaces between the rail ends at the crossing-rail.

It is also an object of the invention to provide a construction wherein a rigid frame is provided for the crossing adapted to support the structure in positive alinement and affording a continuous smooth running-surface for the car-wheel.

The invention consists in the matters hereinafter described, and more fully pointed out, and defined in the appended claims.

In the drawings, Figure 1 is a fragmentary top plan view of a crossing embodying my invention. Fig. 2 is a section taken on line 2 2 of Fig. 1. Fig. 3 is a plan view of an oblique frog embodying my invention. Fig. f is a section taken on line 4 4 of Fig. 3. Fig. 5 is a fragmentary section taken on line 5 5 of Fig. 4.

As shown in said drawings, said crossing comprises a suitable frame which in the present instance is constructed of structural metal, such as the I-beams A and A, arranged parallel at their centers a distance apart approximately corresponding with the distance from center to center of the trackrails to be supported thereon. Extending transversely of said I-beams at any desired angle and affording a support for the crossingtrack are I-beams A which are rigidly secured to the T-beams A and A and are in alinement with an intermediate section of I- beam A, which fits between the I-beams A and A. As shown, all the abutting I-beams are rigidly secured together by means of an gle-plates a, which fit in the intersecting angles formed by the I-beam-supporting frame, and are bolted through the webs of said I- beams, affording a rigid frame at the proper angle for the track. Said frame is further stiffened or braced by bolts a and (13, of which the former extends through the 1fbeams A and A and the angle-plates secured thereagainst, and the latter extends through the webs of the I-beam sections A Supported upon the rigid frame thus formed are the crossing-frogs, in the present instance shown as right-angle frogs, though obviously the angle is immaterial. Each rail of said frog comprises a rail-base B, which is rigidly secured upon the T-beam beneath the same by means of brackets or clamps b, which are shaped on their under sides complementally with the flange of the rail-base and adapted to engage over the same. Said clamps are each provided with one or more bolt apertures registering with corresponding boltapertures in the flanges of the ll-beam upon which the rail-base rests and are adapted to be secured thereto by means of bolts which extend through said brackets and the flanges. The rail-base, as shown, is provided with an upwardlyextending rib having arranged therein. one or more longitudinal, parallel, and upwardly-opening channels, affording parallel upwardly-directed webs 0", having inclined upper faces between which fit complemental downwardly-extending webs c of therail C, the under side of the head of which is provided with upwardly and inwardly directed faces complemental with those at the top of the webs c. The rails are secured to the rail-base by means of a bolt 0, which extends through the Webs c of the rail-head and c of the rail-base on opposite sides of the track, which act not only to rigidly secure the rail-head and rail-base together, but as well equally space the oppositely-disposed rails from each other.

The rail-bases B, which receive the railheads C, extend continuously across the under frame for the crossing and are rigidlvse cured thereto, as before described, and act as a brace for the relatively short I-beam sections A, which fit between the ][-beams A and A, and the rail-bases Bfit between and closely to the rail-bases B, upon the continu ous I-beams A and A, to which they are rigidly connected, in alinement with the siiriim larly constructed track-rails which abut against the outer sides of said rail-bases B and rail-heads C. As shown, each of the railheads is provided with a continuous inwardlydirected flange which extends fora considerable distance on each side of the crossing and which is planed or shaped at each extremity to incline gradually upward, as shown in Fig. 2, so that the trucks of a passing car areelevated slightly in passing the crossing, owing to the car-wheel flanges engaging upon the flange 0 and running upwardly thereon. This permits but a small fraction, if any, of the weight to be supported upon the tread-surface of the rail, thus supporting the truck-wheels over the spaces at the intersections of the rails.

Each of the continuous rail-heads C and C is cut across to aflord a groove to permit the passage of the wheel-flanges therethrough. On the inner edge of each of the inwardly-directed flanges is provided an upwardly-directed rib 0 which serves as a guard-rail.

Obviously frogs for railways such as hereinbefore described may be constructed at any desired angle. In switch or crossing frogs, as shown in Figs. 3 and 4, an I-beam A affords a continuous support for'the rail-bases B, which are secured thereon, as before described, and which at their ends abut against a continuous rail base B, which extends through the frog, supported on the I-beams A A which abut against the sides of the I beam A at the desired angle and are rigidly secured thereto in any suitable manner. The continuous rail-head C rests in and is supported on the rail-base B as described with reference to the crossing-frogs and the railheads C Angle-blocks D D, corresponding with the outer angle of the intersecting rails, are secured in said angles, and wedge-blocks D are fitted to the inner angles and bolts 61 engage therethrough and serve to lock the rails rigidly together.

As shown, the inclined flanges 0 having an an inner guard-rail rib 0 are employed, as before described.

The operation is as follows: The construction is exceedingly rigid, inasmuch as the structural members break joints across the frog, thus interlocking the parts. The inwardly-directed flanges are positively supported on one of the webs c of the rail-base and are planed at the ends to afford a gradual approach to the frog, elevating the wheels just suflicient to permit the same to pass the intervening spaces between the tracks without vibration or concussion.

While I have described a structural-steel base or foundation for the device the same may obviously be modified or a different base employed and the rail-heads and rail-bases may be varied in form to suit the requirements of the particular road using the same. I therefore do not purpose to limit myself bases, an inwardly-directed horizontal flange of the rail-head adapted to support the wheels on the wheel-flanges over the frog and a rib on the inner edge of said horizontal flange acting as a guardrail.

In a railway-crossing, asubbase of structural steel, beams rigidly engaged together at their points of intersection, a rail-base rigidly supported thereon, each comprising parallel members extending across the frog and parallel members at an angle thereto and abutting against the same, clamping-plates engaging said bases to the subbase rail-heads removably supported on and engaged to the rail-bases and an inwardly-directed flange on each rail-head adapted to support the wheel over the intersection of the rail-heads.
