RAILROAD-CROSSING.

SPECIFICATION forming part of Letters Patent No. 718,297, dated. January 13, 1903.

Application filed January 24, 1900- Serial No. 2,624. (No model.)

To all whom, it may concern.-

Beit known that I, VICTOR ANGERER, a citizen of the United States, residinginPhiladelphia, Pennsylvania, have invented certain Improvements in Railroad-Crossings, of which the following is a specification.

The object of my invention is to prevent the rapid wearing away of railroad-crossings at the crossing-point and at the same time to reduce the jar occasioned by the car-wheels striking the edges of the hard-metal plates inserted at the crossings, my invention being particularly adapted to crossings where a steam-road crosses the tracks of an ordinary street-car or trolley line.

In the accompanying drawings, Figure l is a plan view showingaportion of my improved railroad-crossing. Fig. 2 is a section on the line 2 2, Fig. 1. Fig. 3 is an enlarged section on the line 3 3, Fig. 1. Fig. 4. is a perspective View of the main rail, showinga portion of the tapered head; and Figs. 5 and 6 are diagram views.

A is the main rail of a steam-railroad track, made of three sections, in the present instance secured together and to the crossing-rail sections B by cast metal E, which is cast to the rail-sections.

D is a plate of hard metal set into a recess at the intersection of the rails A and B and in the presentinstance grooved to correspond to the grooves of said rails.

The rail A'has a wide head A, which extends the full width of the crossing and slightly beyond each end thereof, terminating at 0. The extended portion is gradually tapered, as shown at c c.

As the wheels of the cars wear away a head is formed on the outer edge of each wheel, as shown in Fig. 5, owing to the fact that the tread of the wheel is usually Wider than the head of the rail, and it is this head that causes a jar at the crossing as it strikes each crossing-rail. By making the head of the rail of sufficient width H at the crossing to support this head and making the extension of the head tapered at each end, as at 0 c, the bead portion of the wheel when the wheel comes to the crossing, as shown in Fig. 5, will be supported, as shown in the diagram Fig. 6, and thus the wheel will pass over the crossing without causing the usual jars.

While I prefer to make the rail A in three sections, as shown, and either of a casting or of wrought metal, it may be cast in one piece, with the hard-metal inserts at the intersecting points. The hard-metalplate in the presentinstance is setinto the recess in the casting E, as shown in Fig. 3, and secured thereto by a wedge passing through a lug extending from the under side of the plate; but other means of fastening may be resorted to without departing from my invention.

I claim as my invention- The combination in a railway-crossing, of the main rails, the crossing-rails, one set of rails having wide heads to take the full width of the tread of the wheels as they pass over the crossing, recesses at the crossing-points, hard-metal crossing-plates mounted in said recesses, said crossing-plates also taking the full width of the tread of the wheels, with lugs on the crossing-plates, and keys for fastening the plates in position, substantially as described.

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

' VICTOR ANGERER.
