speciacation of Letters Patent. Patented June 6, 1911.

application ileilv November 7, 1910. Serial No. 591,133.

Be it known that I, Romair M. WILLIAMS, a citizen of the United States, residing at Junior, in the county of Barbour and State of 'Vest Virginia, have invented a new and useful Rail-Chair, of which the following is a specification.

My invention relates to rail chairs or rail- Way tie-plates of the class that are interposed between the base of the rail and the tie, Stringer, or other substructure, on. which l the rail is held-and supported.

The main object vof my invention is to provide an improved tie-plate which will prevent the longitudinal movement or creeping of the rail over the tie.

Another object is to provide a tie-plato of such construct-.ion as to afford maximum strength with minimum weight, at the. same time affording improved means integral' with the underside of the plate and auxiliary to the usual spikes for gripping the plate to the tie.

Theinvention consists in the construction and combination of parts hereinafter described, and more 'fully pointed out in the appended claims, reference being had to the accompanying drawings, forming a part of this specification.

In the drawings, Figure 1 is a perspective view of a tie-plate embodying my invention; li`ig. i2 is a top plan view of my device with the rail applied thereto, showing the web of the rail in section; Fig.'3 is a plan view of the undersldc of my unproved tie-plate; F1g. 4 is a -longitudinal section of my 1mproved device'applied to a tie,with the rail litted thereto; Fig. 5 is a. central cross section of the tie'plate showing the improved tie-engaging means. i `I A The same numerals refer to similar parts throughput the several views.

Referring to the drawing, (l denotes av rail to which my tie-plate 7 is applied, the plate vbeine substantiall rectangular in outline' and provided on its upper side with a ceutral ilat rail-receiving portion or seat, which is bounded at opposite sides by upwardly extending flanges 8. The flangesv are provided on their inner edges, facing the ailreceiv 'ing seat, with teethk), said teeth being a flapted to bite into and engage the lower flange of the rail and prevent the latter from moving across the plate when the rail is in position as shown in Fig. 4C. These flanges extend transversely across theftieplate and are spaced some distance from the adjacent ends thereof, the distance between -the inner end of the plate andthe adjacent flange being less than the space between the outer end ofthe plate and the outer tlanefe. By the terms inner and outer I re er to the parts of the plate nearestto or farthest from the inner side of the rail when' the plate is in its positiom'trausverselybeneath theV ail. The side 'ofthe flanges facing the base flange of the rail, is substantially vertial, beine; broken at intervals byk the V-shaped teeth 9, while the other or outer side is beveled as shown. i

' Spike holes 10, are made in the are eut through the two flanges, ranged diagonally opposite each other, two holes being :made rin one flange and one in the other. On the under side of the plate, are provided spaced, longitudinally-extendplate and Qing ribs 12 and 13,'extending,throughout the length of the plate, said ribs b'eing divided into sections and shaped to form engaging teeth having -an inclined edge 15, and an abrupt vertical shoulder or face 16, the inclined edge tapering toward that end of the plate which is on the inside ofthe rail when the plate is in position. The inclined edge 15 is tapered or sharpened to facilitatev its insertion into a tie. Itwill be noted .that the inclined edge 15 terminates at its lowest point in the vertical shoulder 16, while at its highest point, or where the said edge merges into the under side of the plate,

jacent tooth. As shown, there are four of the longitudinal ribs, provided on the underV side of the tie-plate; two (marked 12) 'along the side front and rear edges of the plat-e, and the other two (marked 13) being between and spaced equal distances from each other and from the ribs 12. By referring to Fig. 3 it will be seen that the shoulders 1G of thepteeth on the ribs 12 arein alinement with each other, and this ist.rue also of the shoulders of the teeth on ribs 13, but the shoulders of the teeth on the. two sets of ribs 12 are out of alinemcnt with the shoul ders of the teeth of ribs 13. The plate is further provided on its underside, contigu` ous ,to the ribs 12 and 13, with longitudi? nally extending grooves 17, which provide a means for water running along the tie toY escape from between the plate and tie when` eing ar- 9o it nieetswith the shoulder of the next ad-Y they are in position, and thus prevent the` water accumulating under the plate to cause the rotting of the tie.

In providing a tie-plate or chair with depending teeth and having the abrupt shoulder of the same facing toward that end of the plate which is adjacent the outside of the rail, it follows that any tendency of the plate to slide or nieve will be resisted, as the shoulders of the various teeth will engage the grain of the tie at different and spaced points. The flanges on the top of the plate being provided on their innei` edges facing the rail with teeth, will provide a means for preventing any creeping' of the rail on the said plate. To cause the teeth 9 to engage the edge of the base ilange of the rail, notches inust first be cut 1n said edge with a tile, said .notches te be of suthcient depth for the teeth to enter the saine. Obviously the plate may be inade of any desired width, and the number, size and disposition. of the ribs and teeth may be changed to suit varying conditions,

Having thus described any invention,`

what l claim as new and desire to secure by Letters Patent, is:

A railway tic-plate comprising a substantially rectangular plate provided at its upribs, each rib being formed with a series of` connected teeth and each tooth` having a downwardly inclinedy sharpened ledge terniinating at its lowest point in an abrupt vertical shoulder, said sharpened edge extending upwardly and inergig'ig into the underside of the plate and inenting with the shoulder of the next adjacent tooth, the shoulders of all the teeth on all* the ribs facing in the saine direction', -senie of the shoulders being' in alineinent transversely of the plate and sonie out of transverse' alinenient, substantially as described.

In testimony, that I claim the foregoing as iny own, I have hereto aHiXed niy signature in the presence of two witnesses.

ROBERT M. WILLIAMS.
