METALLIC RAILWAY-TIE.

Specification of Letters Patent.

Patented Oct. 24, 1911.

Application filed March 4, 1911. Serial No. 612,339.

To all whom it may concern:

Be it known that I, HENRY C. TINNIN, a citizen of the United States, residing at F armington, in the county of San Joaquin, State of California, have invented certain new and useful Improvements in Metallic Railway-Ties; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to metallic railway ties.

The object of the invention resides in the provlsion of a metallic railway tie which is constructed and arranged so as to cushion under the influence of travel over the tie and thereby obviate to a large extent the jarring and vibration incident to such travel.

A further object 6f the invention resides in the provision of a metallic railway tie which includes means for securing the rails thereto adapted to be adjusted longitudinally of the tie, whereby the rails may be moved toward and away from each other.

\Vith these and other objects in view, the invention consists in the details of con struction and arrangement and combination of parts to be hereinafter more fully de scribed and particularly pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters of refer ence denote corresponding parts in the several views; and in which,

Figure 1 is a plan view of a tie constructed in accordance with the invention, the rails adapted to be supported thereby being removed; Fig. 2, a section on the line 22 of Fig. 1 with the usual rails in place upon the tie; Fig. 3, an end View of the tie illustrated in Fig. 1; Fig. 4, a detail perspective view of the tie with the rail clamping devices removed; and Fig. 5, a detail perspective view of the rail clamping devices which are mounted at each end of the tie.

Referring to the drawings, the tie is shown as comprising a body portion which includes a base 10, and side members 11 and 12. These side members 11 and 12 are bent inwardly at their upper or free edges so as to form independent top sections 13 and 14 respectively. The adjacent ends of these top sections 13 and 14 are then bent downwardly in spaced relation to each other as at 15 and 16 respectively, and these downwardly bent portions are'ter'minated a short distance from the base 10 for a purpose that will presently appear. The downwardly bent portion 15 is provided at one end with bolt openings 17 and on its other end with bolt openings 18, while the downwardly bent portion 16 is provided at one end with bolt openings 19 in registration with the bolt openings 17 and at its other end with bolt openings 20 in registration with the bolt openings 18.

Disposed between the downwardly bent portions 15 and 16 at each end of the tie are rail clamping devices. Each of these devices comprises a pair of overlapping plates 21 and 22. These plates are provided with communicating elongated bolt openings 23 and 24 respectively, which openings in turn are positioned for communication with the bolt openings in the downwardly bent portions 15 and 16 at one end of the tie. Bolts 25 are then passed through the openings in the downwardly bent portions 15 and 16 at each end of the tie and through the openings 28 and 24 in the plates 21 and 22 of each clamping device and said plates thereby secured to the body portion of the tie. It will be noted that by reason of the elongated slots 23 and 24, said plates 21 and 22 may be adjusted longitudinally toward and away from each other to a limited extent. These plates 21 and 22 have formed on opposite ends respectively an inwardly extending clamping finger 26 which is adapted to engage with the base flange of a rail disposed upon the tie. The fact that the clamping devices at each end of the tie can be adjusted longitudinally of the latter will make it apparent that the rails secured by said clamping devices can be adjusted toward and away from each other.

As the downwardly bent portions 15 and 16 have their free edges spaced away from the base 10, it will be apparent that the top sections 13 and 14 can spring under the influence of travel over the tie and thereby present a cushion which will materially aid in absorbing the unnecessary vibration incident to travel;

In order that the tie and rail fastening means heretofore described may be used in the construction of the narrow gage road, additional openings 27 are formed in the downwardly bent portions 15. These open ings 27 are positioned inwardly of the adjacent openings 17 and 18 respectively. Likewise, the downwardly bent portion 16 is provided with openings 28 positioned inwardly of the adjacent openings 19. When the clamping devices are supported upon bolts passed through the openings 27 and 28, it will be apparent that said devices will be positioned nearer the center of the tie and in proper relation to hold the rails of a narrow gage road.

lVhat is claimed is 1. A metallic railway tie comprising a body portion including a base and side members, said side members being bent inwardly to form separate top sections and said top sections having their adjacent edges bent downwardly and terminated in spaced relation to the base, and rail engaging clamps adjustably mounted between the downwardly bent portions of the top sections at each end of the tie.

2. A metallic railway tie comprising a body portion including a base and side members, said side members being bent inwardly to form separate top sections and said top sections having their adjacent ends bent downwardly and terminated in spaced relation to the base, and rail engaging clamps mounted between the downwardly bent portions of the top sections at each end of the tie respectively; each of said clamps comprising a pair of overlapping plates having registering elongated bolt openings at each end, bolts passing through the downwardly bent portions of the top sections and through said openings, heads on opposite ends of said plates respectively projecting above the upper face of the tie and adapted to engage the base flanges of rails.

In testimony whereof, I aflix my signature, in presence of two witnesses.
