UNITED STATES PATENT OFFICE0 CHESLEY A. GORDON, 0F LOS ANGELES, CALIFORNIA, ASSIGNOR TO JOHN H. UDELLY OF LOS ANGELES, CALIFORNIA.

RAILROAD-CROSSING.

Application filed August 28, 1916.

To all who/m. t may concern:

Be it known that I, CHESLEY A. GORDON, a citizen of the United States, residing at Los Angeles, .in the county ,of Los Angeles and State of California, have invented new and useful Improvements in Railroad- Crossings, of which the following is a specification.

This invention relates to improvements in the construction of crossings for railroads in which elevating means are emplo ed to form a bearing surface for the rims o the wheels of the rollingstock to eleva-te the rims of the wheels above the tread surface or heads of the rails at the crossing and so prevent the shock and jar incident to the contact of the wheels with the sholders or ends of the rails at the gaps therebetween.

An object of the invention is to construct a crossing having grooves or channels that intersect or communicate with each other adjacent the corners of the crossing and which provide pockets to receive the rails as well as to receive suitable bearing plates which are adapted to be engaged by the rims of the wheels of the rolling stock to elevate the flanges of the wheels above the gaps at the crossing.

It is a still further object of the invention to construct a railway crossing from a casting comprising spaced members each of which being grooved throughout its length and one of the side walls provided by the groove being shaped to receive one side of a rail, bearing plates or blocks being arranged within the groove to the opposite side of the rail, suitable securing elements passing transversely through the casting for retaining in the grooves thereof the rails and the plates or blocks.

IVith the above and other objects in view the improvement resides in the construction, combination and arrangement of parts set forth in the following specification and falling within thc scope of the appended claims.

In the drawings:

Figure 1 is a top plan view of a railroad crossing constructed in accordance with the present invention,

Fig. .2 is a sectional view approximately on the line 2-2 of Fig. 1,

Fig. 3 is a sectional view approximately on lhe line 3-3 of Fig. 1,

Specification of Letters Patent.

Patented Mar. 12, 1918.

Serial No. 117.356. Y

Fig. 4 is a sectional View approximately on 'the line 4 4 of Fig. 1,

Fig. 5 a sectional view approximately on the. line of Fig. 1, and

Fig. (3 is a perspective view ,of a portion of one of the rail elevating plates or blocks.

As disclosed by the drawings the crossing 1 comprises a pair of spaced members and for the sake of distinction the longitudinal spaced members are indicated by the numerals 2 and the transverse members by the numerals 3. The members 2 and 3 are provided with channels which are extended the entire length otl the said members and the outer walls 4 provided by the said channels have their inner faces at their upper edges or corners grooved, as at 5, and their said inner faces at their lower corners grooved, as at G, the lower wall of the groove 6 being parallel with the lower and horizontally straight wall 7 of the channels, while the upper wall provided by the groove 6 is inclined. By this arrangement it will be noted that the outer walls t of the channels are shaped to snugly receive the rails 8 so that the bearing surface of the heads of the rails will be arranged flush with the upper surface of the crossing and the heads of the said rails have one of their sides resting upon shoulders provided by the wall 4, while of course the base flange on one side of the said rails is received in the grooves 6.

Inserted longitudinally through the space provided by the inner walls 9 of the members 2 and and contacting with the said inner face of the wall and engaged in the fishing spaces of the rails 8 are block or plate members 10. The elements 10 are secured within the channels of the members 2 and 3 preferably through the medium of transversely arranged bolts 11 which are engaged by nuts 12, the said bolts also passing through suitable openings 13 in the webs of the rails 8. The rails 8 when arranged within the channels of the crossing are preferably se cut that their meeting ends will snugly abut at the gaps provided at the intersections of the channels of the members 2 and 3 of thc crossing, and the plates or blocks 10 have their upper surfaces gradually tapered downwardly, as at 14, from a suitable distance adjacent to the said gaps and of course outward of the gaps. The main portion of the plates 10, inward of the tapered ends thereof and indicated for distinction by the numerals l5, are suiticiently elevated to receive the rims of the wheels o the rolling stock to elevate the tread sur? faces or flanges of the said rolling stock so that the same will be brought above the gaps ot the crossing and so the shock and jar incident to the `contacting of the wheels, at the gaps ot' an ordinary crossing, will be entirely dispensed with. rlhe angular ends 14e ot the elevating plates or blocks vl() are tapered gradually from the elevated portions of the said blocks so that the rims of the wheels l will, ride gradually upon the inclined surfaces ll on to the main tread surface 15 et the said members 10. As will be seen, the members l0 in the transversely extending members 3 et' the crossing are termed in sections which have their Vends abutting the members l() in the longitudinally extending parts 2, in this latter part the members l0 are formed of one piece.

From the above description, taken in. connection with the 'wcompanying` drawings, the simplicity ot the device, as well as the advantages thereof will, it is thought, be perfectly apparent to those skilled in the art to which such invention appertains without further detailed description.

Having thus described the invention, what I claim is 2' l. In a railway crossing, a casting comprising spaced members, each of which being ,channeled throughout its length and having the outer side wall shaped to receive the side of a rail, rails within the channels and having their heads arranged flush with the upper surfaces of the crossing, members arranged between the rails and the inner walls of the channels, said members from adjacent to the gaps provided at the inter'- section or' the channels, being disposed only a slight distance below the heads of the rails and from thence being tapered downwardly to their ends.

2. In a railway crossing, a casting comprising spaced members, each of which being channeled throughout its length and having the outer side wall siaped to receive the side of a rail, rails within the channels and having their heads arranged flush with the upper surfaces ot the crossing, members arrangedV between the rails and the inner walls ot the channels, said members from adjacent to the gaps provided at the intersection of the channels, being disposed only a slight distance below the heads ot the rails and from thence being tapered downwardly to their ends, and means passing trans versely through the walls of the channels, through the said members and through the webs of the rails for securing the members and rails within the channels.

In testimony whereof I affix my signature.
