`RAILROAD-TRACK STRUCTU RE.

SPECIFICATION forming part of Letters Patent N o. 593,166, dated November 2, 1897.

Application iiled November 211896. Serial No. 613,034. (No model.)

To @ZZ whom t may concern;

Be it known that EDWARD SAMUEL, formerly a citizen of the United States, residing at Philadelphia, Pennsylvania, but now deceased, did during his lifetime invent certain Improvements in Railroad-Track Structures, of which the following is a specification.

This invention relates to certain improvements in wearing-pieces or risers used to carry wheels on their flan ges across the intersecting points of rail structures.

The object of the invention is to facilitate the manufacture and to lock the riser to the rails by perforating the rails at intervals, so that the metal which forms the riser when in a molten state will pass through the perforations and unite under the flange of the rail or to so shape the perforations tha't the metal within them will lock the riser to the structure, as clearly described hereinafter.

In the accompanying drawings, Figure 1 is a plan view of a crossing, illustrating the invention. Fig. 2 is an enlarged transverse sectional View en the line 2 2, Fig. 1. 3 is an enlarged sectional View on the line 3 .3, Fig. l. Fig. 4 is an enlarged sectional view illustrating a modification inwhich is shown the cast metal which unites the rail-sections together forming the riser. Fig. 5 is a view of another moditcation, and Fig. 6 is a view showing the invention applied to astraight tram-rail.

Referring in the first instance to Figs. 1,2, and 3, A is the main-line rail, and B is the crossing-rail. These rails are secured together in the present instance by a casting D, the cast metal passing through perforations in the webs of the rails, thus holding the rails rigidly together without the use of bolts or rivets. It will be understood, however, that the invention can be used in rail structures in which the rails are bolted or riveted together and may be made entirely of a casting, and while there is illustrated a crossingfrog it will be understood that the invention can be used at any crossing or switch-mate or at any point in a rail where it is wished to use a riser.

In the present instance the base of the groove d of the rail A is perforated, as Well as the base of the groove b of the rail B, and

a mold of such form is prepared and applied to the rail that when molten metal is poured onto the rail-section it will new through the series of perforations in the two rails and unite underneath the iiange, forming a lock, as clearly shown in Fig. 3. A suitable cap is placed over the groove of the rail so that the riser will be of a given height.

In some instances a core maybe used when it is wished to cast the two rails together to 6o formthe rail structure, so that a recess will be left directly under the flange of the rail where the riser is to be locked, so that when the cast-metal section D is cold the core can be removed and the metal to form the riser can be poured into a suitable cap and through the openings in the 4Bange of the rails, the metal flowing into the space formed by the core and the metal passing through the several openings uniting under the flange of the 7o rail.

In Fig. 4 there is shown a modification in which the cast metal which unites the rails together is allowed to rise through the perforations and into the groove of the rail to such aheight as may be considered necessary to form the riser, and the upper surface of this metal may run against a chill, so as to give it a harder surface should it be deemed necessary. 8o In Fig. 5 the perforations in the rail are formed at an angle and the lower section of the riser is dispensed with, the metal in the perforations holding the riser in position.

In Fig. 6 there is shown an improved form 85 of riser applied to a rail having a straight tram, and it will be understood that the invention may be applied wherever a wearingplate is required in a structure of the character described.

lVhat is claimed as the invention is- 1. The combination in a track structure, of a rail having a series of perforations with the riser or wearing-plate resting upon the rail and having a series of lugs extending into the perforations of the rail and acting to hold the riser in position, substantially as described.

2. The combination of a rail,perforated side flange thereof, with a cast-metal riser or wearing-plate having two sections, one above and roo 4:. The combination in a, track structure, of

the rails perforated at the point Where a. riser is to be formed, With cast metal binding the rails together, said metal extending through the perforations and forming the riser, sub- 15 stantially as described.

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

WILLIAM SELFRIDGE, Eecutor of the estate of Edward Samuel, de-

ceased.
