Tin-PLATE.

Specification of Letters Patent.

Patented Apr. 11, 1911.

Application filed August 19 1909. Serial No. 513,568.

To all whom it may concern; I

Be it known that 1, WILLIAM T. BEN'rz, a resident of Elyria, in the county of Lorain and State ofOhio, have invented a new and useful Improvement in Tie-Plates; and I do hereby declare the following to be afull,

, cheap, simple-and eflicient form ofa tieplate'for railway rails .which can be manufactured by rolling in a rapid, easy and convenient manner, andwill provide fort-he proper supporting of the rail used on such plate, will also hold the plate and rail in proper position, and will provide means thereon for the proper supporting of the head of the spikes employed, as well as .What are known. as screw-spikes, if used in connection therewith.

My invention consists, generally stated,'in the novel arrangement, construction and combination of parts, as hereinafter more specifically set forth and described and particularly pointed out in the claims.

To en able others skilled in the art to which my invention appertains to construct and use my improved tie-plate, I will describe the same morefully, referring to the accompanying drawing, in which I Figure his a side view of'my improved tie-plate showing the same in position on the .tie and with the rail and spikes. Fig. 2 is a top plan view of the plate. Fig. 3 is an end view of the same. Fig. -1 is a side View of a portion of the rolled bar for forming my improved tie-plate.

like symbols of-refere'uce herein indicate like parts in each of the figures of the drawing. v

As illustrated in the drawing, 1 represents my improved tie-plate, which is preferably fori'ned by rolling from a metal bar or billet, such as steel, and is provided with parallel ribs or flanges 2 extending longitudinally beneath the under surface of the plate and located adjacent to the edges thereof. Between the ribsor flanges are the ribs or flanges 3, which are of less depth than said ribs or flanges 2, and such ribs or flanges and 3 are wedge-shaped so as to provlde for the pointed ends at respectively thereon to facilitate their being driven into the grain of the wood of the tie A, as show-n in Fig. 1..-

The upper surface of the plate 1 is provided with a series of parallel grooves 5, which are preferably arranged above the ribs or flanges 2 and 3, and such plate may,

if desired,' be provided with the side ribs or flanges 6 extending beyond the ribs or flanges 2. The upper surface of the plate 1 is also provided with the rail abutting shoulder Tin order to sustainthe rail 7), such as is shown in 1 and prevent the same from spreading. The outer edge of the flange Z) of the rail 6 is adapted to engage with the abutting shoulder 7 on the plate 1, and thereby pre vent such rail from moving relatively to the plate, as well as preventing the throat cutting of the spikes 0 passing through the holes I 8 in such plate and entering the tie a, as shown in Fig. 1. Theabutting shoulder 7 is in the form of a rib or flange and it extends across the plate 1 and the grooves 5 in the same.

The spike-holes 8 in the plate 1 are shown as being four in number, two located in each end of the plate and between the outer grooves 5 and the next of the said grooves thereon, and the inner portions of such holes on the end of theplate having the abutting shoulder 7 extending across said holes, as-

shown in Figs. 1 and 2.

Around the outer portions ofeach of the spike holes 8 in the plate 1 anti preferably extending to the-ends of the plate, are the reinforcements or bosses 9 for the heads (Z of the spikes c, which extend up from the tipheads (Z and the fronts of such heads aresupported by the flange Z) of. the rail 6.

In Fig. 1, the spikes 0 are of the screw form 'whichhave their heads (Z of circular form with inclined or tapered under-faces ("i and the bosses 9 on the plate 1 are preferably concave or grooved on their upper faces and at an upward inclinefrom the inner to the outer ends of the same, as at 10, to conform to the faces 0, so that such faces will be seated within said grooves 10 and thereby give such spike-heads (Z a proper surface and adjacent to said shoulder, while theflanges 2 and 3 will be formed on the lower surface of the plate 1 by the lower roll (not shown). After the bar 11 has been so formed to shape, it is cut or sheared across and centrallyof the double bosses 12 and on the dotted lines,.such as is shown at '13 in Fig. 4, to form the lates 1 which will thereby permit each of the two several portions of such bosses 12 on the ends of adjacent plates to form the bosses 9 on opposite sides or ends of such plates. The spike holes 8 can be formed in the bar 11 after such bar is formed or in the plates 1 after being cut from said bar or-during the operation of cutting, as desired. ,1

The spike holes with their reinforcements or bosses can be varied in number and their positions on each side of the plate can be changed, while various other modifications and changes in the design and construction of my improved tie-platemay be resorted to without departing from the spirit of the invention, or sacrificing any of its advantages. It will thus be seen that my improved tie-plate will obviate the failure from distortion and bending of the spike under the head from the lateral thrust of the rail and imperfect application and non-support back of such head. The plate will'insure a good bearing of the flange or head of the spike and will prevent the spreading of the rail, by reason of the rail abutting shoulder, and

such shoulder will prevent the rail base from throat cutting the head of the spike- It will also be. seen that the depending flanges on therplate willenable such plate to be securely fastened to the tie, and when such plate is thus .in position it has a stronger seat and'preyents decay of thetie owing to the arched construction of such flanges.

Through the grooves the plate is also made lighter in welght and thereby renders the same more economical and cheaper in construction, while it Wlll possess the. required tength and will not be liable to creep when ipositiori or permit the rails to creep, and" (f/1111101" be. liable to wear out the ties on which it is used.

The bar from which my improved tieplates -arelfo'rmed will-enable such plates to be"rolled in continuous lengths and then meander, ent from such bar, while the formation of such bar will permit the easy and rapid IOllll\ of the same, and permit the tie-plates to be formed therefrom rapidly and conveniently, so that with the formation of the spike-holes within the same the tie-plates are ready for. instant marketing and use'with the rails.

What I claim as my invention anddesire to secure by Letters Patent is 1. A tie-plate having flanges on its under surface extending longitudinally with respect to and adapted to be embedded in a tie, grooves 011' its upper surface extending parallel with said flanges, a transverse shoulder on its upper surface, and bosses on its upper surface and between said grooves to reinforce the'back of the spikes.

2. A tie-plate having flanges on its under surface extending. longitudinally with re spect to and adapted to be embedded in a tie, grooves on its upper surface extending parallel with said flanges, a transverse shoulder on its upper'surface, and bosses on its upper surface and between said grooves to reinforce the back of the spikes, said bosses having their upper faces inclined up- Wardly and outwardly from the spikes.
