RAILWAY-CROSSING.

Specification of Letters Patent.

Application filed July 10, 1911.

Patented Jan. 23, 1912. Serial No. 637,823.

To all whom it may concern:

Be it known that we, COLUMBUS H. Cums- TIAN, a citizen of the United States, andi resident of Atlanta, in the county of Fulton; and State of Georgia, and EARL H. HUTCHE-i SON, a citizen of the United States, and resi-'; dent of Augusta, in the county of Richmond and State of Georgia, have invented certain new and useful Improvements in Railway Crossings, of which the-following is a specification, reference being had to the accompanying drawings. 7

The invention relates to railway crossings of that description which areformed of metallic castings placed at the intersection of two tracks to form continuations of the rails past the intersection.

In many of thecrossings in common use, to make the connections with the ends of the rails, it is necessary to cut the ends of the rails to particular shapes to fit the rail connections of the crossing.

One of the objects of the present invention is to provide a crossing that can'be joined to the ends of rails that have been cut squarely across.

ence characters designate corresponding parts, Figure 1 is a plan view, broken away in parts, of a crossing embodying the invention. Fig. 2 is a perspective view of, the

main part of the crossing, the flange-block being removed. Fig. 3 is a perspective view of the flange-block. Fig. 4 is a sectional view on the line 44 of Fig. 1. Fig. 5 is a plan view, broken away in parts, showing a modification of the invention. Fig. 6 is a planview of the flange-block of the modification. Fig. 7 is a cross-section of the same.

As shown in Figs. 1 to 4, inclusive, the

crossing is of a generally rectangular formation and is adapted to tracks intersecting each other at right-angles. The base plate 1 supporting the crossing is of considerable area so as to give an extensive foundation when the crossing is embedded in the roadbed and enables it to withstand the loads and shocks of passing vehicles. Integral with the base plate 1 and projecting from its upper surface is the seat-box 2 with its bottom elevated somewhat above the surface .base 6 of an abutting rail, extending upwardly from the groove is the vertical slot 7 to receive the web 8of the rail, and at the upper end of the slot the top edge of the wall is recessed, as at 9, to receive the crown 10 of the rail. By means of this construction the abutting end of the rail can 'be cut off at right angles to its length 1 and the squared end without any special shapin fitted into-the opening in the wall forme by the horizontal groove 5, the vertical slot 7 and the recess 9. The base 6 engaging with the groove 5 will hold the end of the rail against upward movement, and the web 8 engaging the slot 7 will prevent any sidewise movement of the end of the rail. Projecting outwardly from the wall 4 adjacentto the slot 7 is the lug -11 bolted to the web 8 of the rail by the bolts 12, which prevents any longitudinalmovement of the rail relative to the crossing. In the upper edge of each wall 4 adjacent to the recess 9 and along the side of the end of the rail is the groove 13' to receive the flange of a passing wheel. Fitted in the seat-box 2 is the flangeblock 14 with its surface flushwith the treads of the adjacent rails and the top edges of the walls 4 of the seat-box. On the surface of the flangeblock are the intersecting treads 15 forming continuations of the treads of the adjoining rails, and along the sides of these treads extend theintersecting grooves 16 to permit the passage of the flanges of the wheels traveling on the treads. The grooves 16 register with the grooves 13 in the walls of the seat-box. The surface of the flangepassing wheels and prevents the strain from coming against the walls of the seat-box. Upward displacement of the flange-block is prevented by screws 18 passing through the same into the bottom of theseat-box. It is evident that a worn flange-block can be readily replaced by a new one by loosening the screws 18. As shown by full lines in Fig. 2 and dotted lines in Fig. 4, there is an enlargement 19 at the upperend of the screwhole in the bottom of the seat-box for one of the screws 18. After the screw in this particular hole has been removed a hook can be inserted through the screw-hole'in the flangeblock into the enlargement 19 to facilitate the removal of the fiangeblock.

By the foregoing construction a crossing is provided which can be readily and easily put in place and secured,-one to which rails with square-cutends can be easily attached, one which will sustain wear and in which worn parts can be readily replaced.

In the modification shown in Figs. 5 to 7 inclusive, the crossing is adapted to tracks intersecting at acute-angles. On the baseplate 21 and integral with the same is the circular seat-box22. In this seat-box is lugs 27 extending fromthe wall of the seatbox 22 and bolted to the ends of the rails.

Having thus described our invention, what we claim and desire to secure by Letters-Patent is,

-1. In a railway crossing, a base-plate, a

seat-box integral with the base-plate provided witha central opening in its bottom and having openings in its side-walls, a flange-block fitted in the seat-box provided with rail-treads on its upper surface, a stud projecting from the under side of the flange- .block and fitting in the central opening in the bottom of the seat-box, rails resting at their ends onthe base-plate forming with the rail-treads on the flange-block continuous tracks through the openings in the From box.

side-walls of the seat-box, and-means for securing the ends of the rails in place.

2. In a railway crossing, a base-plate, a seat-box on said base-plate integral with the same with openings in its walls to receive the ends of rails, rails with square-cut ends entering said openings in the walls of the seat-box, spurs projecting'from the walls of the seat-box secured to the ends of the rails, a flange-block fitted in said seat box provided with intersecting treads on its face to form continuations of the treads of the rails .and having flange-grooves adjacent'to the treads, and a stud projecting from the under side of the flange-block and engaging the bottom of the seat-box. v

y 3. In a railway crossing, a base-plate, a

seat-box on said base-plate integral with the the under side of the flange-block into the bottom of the seat-box.

4. In a railway crossing, a base-plate, a

seat-box on said base-plate integral with the same with its wall having an opening formed of a horizontal groove to. receive the base of the rail, a slot extending vertically upward from the horizontal groove to receive the web of the rail and a recess at the upper end of the vertical slot to receive the crown of the rail, a rail with a square-cut end entering said opening, a spur projecting outwardly from the wall of the seat-box and attached to the rail, and a flange-block seated in said seat-box having intersecting treads on its face to form continuations of the treads of the rails attached to the seat- In testimony whereof we hereunto aflix our signatures in the presence of two wit nesses.
