EDWARD SAMUEL, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO THE WILLIAM WHARTON, J R., &; COMPANY, INCORPORATED, OF SAME PLACE.

STRlNGER-PLATE.

SPECIFICATION forming part of Letters Patent No. 504,176, dated August 29, 1893.

Application filed January 5, I 893- Serial No. 457,365. (No model.)

To all whom it. may concern:

"Be it known that I, EDWARD SAMUEL, a citizen of the United States, and a resident of Philadelphia, Pennsylvania, have invented 5 certain Improvements in Stringer-Plates, of

which the following is a'specification.

The object of my invention is to decrease the width of the stringers used in street railway construction upon which the rails are rail to the stringers. This object I attain in the following manner, reference being had to the accompanying drawings, in which- Figure 1, is a sectional view through the stringer, rail and stringer plate. Fig. 2, is a perspective view of the plate shown in Fig. l; and Fig. 3, is a perspective view showing the plate slightly modified.

In the construction of street railways in which stringers are used/1t has been customary to make the stringers of considerable width in order that the rails may be securely fastened thereto, and to give sufficient support for the securing spikes.

By my improvement I am enabled to reduce the width of the stringers toa width little more than the width of the base flange of the rail.

Referring to the drawings, A is the stringer. B is the rail of the girder type, havinga base flange, web and ahead, and it will be noticed that the inner base flange of the rail is on a line with the edge of the stringer, and that the stringer extends beyond the outer edge 3 5 of the base flange, giving suflicient room for the spike E to'pass into the stringer and overlap the base flange. If desirable, this may however be reversed.

I provide at intervals a plate D which rests 40 directly upon the stringer, and supports the rail. This plate D has a portion d which extends between the rail and stringer, and a portion d which extends down on the side of mounted, and to facilitate the spiking of the the stringer, and I strike up a lip d from the plate, as shown clearly in Fig. 2, which laps over one side of the base flange, and openings e are formed in the plate for the passage of the spikes E, holding down the other side of the base flange, and openings e are formed in the portion at of the plate, so that spikes F may be driven through the plate into the stringer from the side, thus securely fastening the plate to the stringer and to the rail. The outward lateral thrust upon the rail is taken by the plate D, and therefore the stringer will not split at the spikes E, owing to the insufficiency of material.

In Fig. 3, I have shown aplate having two lips d and a single spike hole 6, and a single spike hole e, this being the equivalent of the plate shown in Fig. 2.

I claim as my invention- The combination of the rail having a base flange, a stringer slightly wider than the base of the rail, a stringer plate mounted between the rail and the stringer and having a portion extending down on one side of the stringer, with lips at the junction of the vertical and horizontal portions of the plate, said lips extending over one edge of the base flange of the rail, one or more spike holes in the opposite end of the horizontal portion of the plate adapted to receive a spike which passes into the stringer and clamps the rail thereto, with one or more spike holes in the vertical or side portion adapted to receive a spike or spikes which enter the side of the stringer, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of 80 two subscribing witnesses.

EDWARD SAMUEL.
