Be itknown that I, WILLIAMB. JOHNSON, a citizen of the United States, residing at Gallup, in the county of McKinley and Ter- 5 ritory of New Mexico, have invented a new and userul Railroad-Tie Plate, of which the following is a specification. i This invention relates to tie-plates for railroads, and has for an object: to provide a defeatures of economy, durability, utility, and

efficiency. i I k A further object of the invention is to'provide a tie-platehaving ribs along the undersurface parallel with and between'the longitudinal edges of the rail, and in such position that the force employed in driving. the ribs into the tie will be imparted directly above the ribs, the Weight of the rails and the assing trains being also directly'above the ri s. 4 Withthese and other objects in view the present invention consists in the combina-fi tion and arrangement of parts, as will be here: inafter fully described, shown in the accom- 2 5 panying drawings, and particularlypointed out in the a pended'claims, it being under- I stood that, clian'ges in the form, proportion, size, and minor details may be made without departing from the spirit or sacrificing any 's invention. In the :h'awings,' Figure]. is a view of the improved tie-plate in end elevation applied to' a tie and with arail shown in transverse section thereon. Fig. -2 is- 'a perspective responding parts in all the figures of the" drawings. ,7

In its preferred embodiment the improved plication comprises a plate designated as a whole by'the numeral 10 and with a channel 11 formed in its upper surface, with the upstandin side walls 12 adapted-t0 receive between t cm the base ofthe rail13. In the.

adjacent sides of the channel ll o enings 14.

' are formed through the plate an the walls 12 to rec ve spikes 15, by which the plate is secured upon the tieand the railsecured a short distance into the body of the plate or inwardly from the inner faces of therail-engaging ribs 12, so that .theinner faces of the spikes bear with full force against the edges ,of the tie-fianges of the rails and firmly bind them in position and readily adapt themselves to varying widths of rails. Along the under side of the plate are formed ribs 16,

having sharpened longitudinal edges, as at 17, to out into the fiber of'the tie 18 and across the rain thereof. The plate outside the channe walls is beveled or reduced in thickness at the edge, as shown at 19, It will be readily seen that the ribs 16, be-

ing directly under the channel 11, the blows of a sledge in driving the ribs into the fiber will fall directly over the ribs, and thereb lessenthe liability of breakage. Again, wit

the ribs 17 disposed beneath the rail 13 and the outer edges of the plate 10. reduced in thickness and weight, as shown at 19, the

strainis reduced, and the tendency of the plate to be more securely embedded in the material of the tie is correspondingly increased under the influence ofthe blows employed to force'the'ribs 1*? into the tie and also I under the influence of the weight of the rails and the hammereblowslimparted by passing trains. The portion of the plate 10 between the rail sup porting ribs 1 2 being therefore relatively thick and theportions .19 outside the rail-supporting ribs being relatively thin, the downward pressure exerted the drivinmof the spikes l5 and by the blows required to force the ribs 17 into the tie increases the density of the tie material between the latter ribs, and therefore insures a more secure bed :for the same:

While the bottom of the channel 11 is shown as parallel with the base of the plate, it will be-understood that in those positions whereit is desirable to set the rail at an in- Havin thus described the invention, What I is claime is c 1. A railway-tie plate having a relatively thick central portion and relatively thin side portions and with spaced ribs for hearing against the sides of the rail and disposed at the juncture of the-thicker centralportion and the thinner side portions, and tie-engag ring ribs beneath the thicker portion and bc-- tween said rail-engaging ribs.
