RAILWAY-TRACK STRUCTU RE.

SPECIFICATION forming part of Letters Patent No. 705,131, dated July 22, 1902.

Application filed November 19,1901- Serial No. 82,852- (No model.)

To all whom it may concern.-

Be it known that I, JOHN H. PFLIEGER, of J ohnstown,in the county of Oambria and State of Pennsylvania, have invented a new and useful Improvement in Railway-Track Structures, 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 has relation to railway-track structures of that type which employ a wearplate of durable material removably seated in the body of the structure and constituting the track-surfaces at the points where two tracks meet or intersect and where the structure is subject to the greatest wear in service.

The object of my invention is to provide means of novel, simple, and efficient character by means of which the wear-plates may be rigidly secured in the body of the structure in such a manner as to permit them to be readily removed and replaced when necessary, a further and more special object being to avoid the necessity for accurate fitting or machine-work in the construction and assembling of the parts.

To this end my invention consists in the novel construction,combination,and arrangement of parts, all as hereinafter described, and pointed out in the appended claims, reference being had to the accompanying drawings, in which Figure 1 is a plan View of a frog or crossing embodying my invention; Fig. 2, a side elevation of the same, and Fig. 3 a section on the line 3 3 of Fig. 1.

In the figures the letter A designates the rail members of the structure, which are shown as being united by a central body B ,of cast metal, formed with a pocket or recess therein and in which is seated the wear-plate O, which is provided with track-snrfaces and flangeways which aline with the corresponding surfaces and flangeways of the rail membersa My invention is, however, equally well adapted to structures of that type in which the rail members and the central body consist of one integral casting in which the pocket for the plate 0 is cored. The side walls of the pocket are formed with apertures cored therein and leading outwardly from the plate-pocket for the purpose of receiving the fastening members or keys D, which are of approximately Z form, with the lower arms turned upwardly at the extremities, as shown at d in Fig. 3. The plate is seated in its pocket and its upper surface properly alined with reference to the tracksurface of the rail members by placing thin shims or blockings underneath it to support it at the proper level. The fastening members or keys D are then inserted and seated in the manner shown in Fig. 3 with their upper horizontal arms" catching over the edge portions of the plate and their lower hori- Zontal arms extending outwardly from the horizontal apertures in the side walls of the pocket. They are then secured and made to bind the plate to its seat by driving wedges E between the upturned end portions d and the surface of the body B. These wedges draw the fastening members or keys downwardly and outwardly and cause them to hold the plate securely to its seat with respect to both lateral and vertical movement, the upper edge portions of the plate being preferably slightly recessed or grooved out to re ceive the arms (1 of said members. To provide seats for the wedges E, the body Bis provided with the lugs or bosses E. After the fastening members or keys have thus been seated and secured the space underneath the plate and between the same and the side walls of its pocket is filled with spelter or other similar material in the usual manner and as indicated at G.

To remove the plates when necessary, small portions of the adjacent pavement are removed to permit the wedges E to be driven from their seats, after which by chipping out some of the spelter from around the said keys or members they maybe readily withdrawn and the plate pried or lifted from its seat, or,- if desired, by means of a suitable tool the up per arms at of the fastening keys or members can be cut off and the plate unseated.

While I have only shown the invention as applied to a frog or angle-crossing, it is ob vions that it may be applied to other specific structures in which two or more tracks meet or intersect.

I do not wish to limitmyself to the exact construction and arrangement which I have herein shown and described, as it is obvious that slight changes may be made in the details thereof without departing from the spirit and scope of my invention as claimed. I

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

1. In a track structure, the combination with a wear-plate seated in a pocket in the structure, of fastening members or keys arranged to grip the side portions of said plate and having arms extending outwardly through the side walls of the pocket, and Wedges or the like engaging said arms and securing the said members or keys in gripping engagement with the plate.

2. In a track structure, the combination with a wear-plate seated in a pocket in the structure, of means for securing said plate in its seat, consisting of angular fastening members or keys engaging the plate and extending outwardly through the side walls of the pocket, and wedges driven between said members or keys and the body of the structure.

3. In a railway-track structure, the combination with a body portion having a pocket therein and apertures leading outwardly from the pocket through its side walls, of a wearplate seated in said pocket, and approximately Z-shaped fastening members seated between the side of the plate and the walls of the pocket, with their upper arms engaging the plate and their lower arms extending outwardly through said apertures and secured by wedges.

4. In a railway-track structure, the combination with a wear-plate seated in a pocket in the body of the structure, of means for fastening said plate consisting of angular, ap proximately 2 shaped keys, whose upper arms grip the plate and whose lower arms extend outwardly through the side walls of the pocket and are turned upwardly at their ends, and wedges driven between said upturned ends and the body of the structure.

5. In a railway-track structure, the combination with the body portion having a pocket, and apertures leading outwardly from said pocket through its side Walls, of a wear-plate seated in said pocket, and the fastening keys or members D having the arms cl engaging the plate, the arms extending outwardly through said apertures and terminating in the upturned ends 01, and the wedges E driven between said upturned ends d and the body of the structure.

In testimony whereof I have aflixed my signature in presence of two witnesses.

JOHN H. PFLIEGER.
