SPECIFICATION forming part of Letters Patent No. 617,167, dated fanuary 3, 1899.

Original application filed August 22,1898,SerialNo.689,211. Divided and-this application filed September 20, 1898. Serial No. 691,437. (No model.)

To all whom it may concern:

Beit known that I, CARL F. KREsS, Jr., of Johnstown, in the county of Cambria and State of Pennsylvania, have invented a new and useful Improvement in Railway Switch- Mates, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to switch-mates for railways, and belongs to that class of switchmate in which the rails are cut and fitted and secured together with a metal chock between them.

The present application is a division of my prior application for Letters Patent for a railway-track structure, filed August 22, 1898, Serial No. 689,211. In the said prior application I described and claimed, broadly, railway-track structures in which the chock of the structure is secured to the inside rails by clamping the inside and outside rails together (after they have been fitted together) and pouring metal between them, thus dispensing with the usual patterns, molds, dre., in which the heads of the inside and outside rails are secured directly alongside one another, so that they substantially cover the chock and present a floor-surface composed of the hard steel rails and in which the head of the pointrail is extended beyond the point and cut to form a portion of the floor.

My present invention covers a switch-mate made in accordance with the aforesaid application, but containing certain more specific features of invention not claimed therein. These features, with the advantages accruing therefrom, will appear in the course of the following description.

Referring to the drawings, Figure 1 is a plan view of a switch-mate embodying the features of my invention. Figs. 2-and 3 are transverse sections on the lines 2 2 and 3 3, respectively, of Fig. 1.

A designates the straight main-track rail, which is continuous and of unchanged section throughout its length. Bis the pointrail of the branching track, and D a guardrail. I have shown all these rails of ordinary T-section cut and fitted together.

The point C of the mate is formed by cutting the head of the branching rail. The llanges of the rails B and D are cut so that they may fit against each other and against rail A, the heads of the three rails lying alongside each other. When so cut and fitted, the three rails are clamped together and metal is poured between them, openings being preferably formed in the web of rail B, so that the rail will be securely embedded in the metal chock, while the latter will conform strictly in contour to that of the outside rails. By casting in this manner it is obvious that no patterns nor molds need be used, as rails A and 'D themselves form the mold. The main rail A and guard -rail D may be secured to the outside of the unitary structure formed by chock E and rail B by means of bolts and nuts, as shown.

The door of the structure' is formed by grooves cut in the heads of the branching and guard rails.

d is that part of the floor formed by the guard-rail, and b that portion formed in the head of the branching rail. A part of the groove b extends beyond the point c of the branching rail, so that a complete floor of rail steel is provided except at E', where the cast chock is not covered. It will be noted that groove b is cut somewhat deeper than groove c. When keeping to the main track, the tread of the wheel should preferably bear on the head of rail A at all times; but to protect point C it is better practice to lift the wheel from its tread to its `lianges when taking the branching track. It is for this reason that part of the floor formed by groove a is in a higher plane than that part formed by groove b.

Having thus described my invention, what I claim, and desire to protect by Letters Patent, is

1 In a switch-mate a point-rail forming a continuation of the branching track,a straight main-track rail, a guard-rail, and a chock cast to the said point-rail and iitting under the heads of the three rails, said three rails being fitted together with their heads bearing against each other, and angeways cut in the rail to form the floor of the frog.
