TRACK STRUCTURE.

SPECIFICATION forming part of Letters Patent No. 545,821,-dated September 3, 1895. Application filed November 3, 1894. Serial No. 527,809. (N model.)

to all whom it may concern.-

Be it known that I, EDWARD SAMUEL, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Track Structures, of which the following is a specification.

The object of my invention is to provide a frog, switch, or other rail structure with an independent special shape of durable metal,

[0 forming a continuation of the wearing portionof the rail or rails, said shape being removable, as fully described herein after, reference being had to the accompanying drawings, in which- Figure 1 isa plan View of a railway-frog made in accordance with my invention. Fig. 2. is an inverted sectional plan view on the I line 2 2, Fig. 3. Fig. 3 is a transverse section on the line 3 3, Fig. 1. Fig. 4; is a longitudi- 2o nal sectional view on the line 4 4, Fig. 1.

Fig. 5 is a plan View of a switch-mate, illustrating my invention; and Fig. 6 is a longitudinal sectional View on the line 6 6, Fig. 5.

Referring, in the first instance, to Figs. 1

z 5 to 4:, inclusive, which illustrate a railwayfrog provided with my improved independent special shape constituting a wearing-plate, A is a rail extending throughout the structure, and B B are rail-sections extending into the structure a certain distance, as indicated in Fig. 2, the head of the rail A being cut away between the points was, leaving only the base flange and web, as shown in Fig. 3. The rails A and B are secured together by a cast- 5 metal section 0, the upper face of this section, between the railsA and B, being formed to receive the special center or crossing piece D, which is preferably made of metal of greater durability than the rails. The face of the piece D is shaped so as to form a continuation of the heads of the rails. The railsA and B have perforated Webs in the present instance, and in forming the structure said rails are mounted in suitable molds, into 5 which the cast metal is so poured that it will flow through the perforations and along the sides of each rail. Thus when the cast metal is set the several rails are firmly attached to the casting. On the face of the casting O is a rib c, Fig. 3, adapted to a recess in the bottom of the plate D, so that when the plate is adjusted on the casting it will align with the rails.' Depending from the plate D is a series of lugs d, which extend through openings 0 in the cast-metal section 0, and keys or cotters are adapted to openings in the lugs,

so as to hold the plate down upon the castmetal section. Between the plate D and the cast-metal section 0, I preferably insert a softmetal lining 6, although this may be dispensed with in some instances.

It will be understood that nuts may be used in place of the keys, and other means of fastoning may be resorted to without departing from my invention, and more than one rib may be formed on the cast section C, in order to relieve the projections or lugs from side strains.

Figs. 5 and 6 illustrate the application of the invention to'a switch-mate, and will be readily understood without detailed descrip tion.

I claim as my invention 1. A frog or otherrail structure composed of two or more rails permanently secured to gether by a cast metal section forming a recess at the center or crossing point, with a hard metal plate secured to the cast metal section of the structure, the upper face of said plate forming a continuation of the rail sections, substantially as described.

2. The'combination in a frog or other rail structure, of two or more rails permanently secured together by a cast metal section forming arecess at the center or crossing point, holes therein, with a hard metal plate adapted to the recess and having depending lugs passing through the holes in the cast metal section and securing devices adapted to the lugs, substantially as described.

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

EDWARD SAMUEL.
