ANTICREEPING'DEVICE FOR RAILWAY-RAILS.

Application filed November 17, 1926.

The invention relates to that class of anticreeping devices in whicha rolling member is interposed between the-base-flangeof the rail and an adjacent fixed surface on the tieplate, adapted to engage such edge by a cramping action induced by the creeping movement of the rail relatively to the tieplate, and it relates more particularly to a tie-plate adapted for such service.

The object of the invention is to provide a tie-plate having the required bearing surface for the rolling member. and means for holding the latter against vertical escape, which will serve efficiently and may be easily and economically manufactured, and another important object is to provide'the tieplate with such bearing surfaces at each end, thus insuring its proper positioning relatively to the rail and permitting its reversal for further service when worn.

The invention consists in certain novel features of construction and arrangement by which the above objects are attained, to be hereinafter described and claimed.

The accompanying drawings form a part of this specification and show an approved form of the invention.

Figure 1 is a plan view showing the improved tie-plate and a portion of a rail supported thereon and engaged therewith.

Figure 2 is a side elevation corresponding to Figure 1, the rail being shown in dotted lines.

Figure 3 is a vertical section taken transversely of the rail, on the line 3-3 in Fig ure 1.

Similar reference numerals indicate the same parts in all the figures.

The rail may be of the usual type having the head 5, vertical web 6 and base- flanges 7 and 8, and is supported upon a tie-plate of peculiar construction which is held to the ie, not shown, by spikes 9.

The body 10 of the tie-plate has two simir lar separated ridges 11 and 12 formed there on parallel with the base- flanges 7 and 8 and receives the latter between them and each has a vertical face next tothe rail; the ridge 11 serves as an abutment for the flange 7 to which it lies closely adjacent while the ridge 12 lies a little distance from the flange 8, the space between them receiving a corrugated elliptical roller 13 adapted to engage the ridge and flange.

The central portion of each end of the Serial at. 148,832.

tie-plate is provided with cuts extending from the edge nearly to the ridge, as shown, and the tongue of metal thus formed is fold- 'ed or bent upwardly upon itself, to form the overhanging lips 14 and 15 projecting induction of the roller 13, and the space heneath the lip is ofsufiicient height to permit the roller to move freely therein longitudinally of the base-flange.

Spike-holes 18 in the ridge 11 at one end i of the tie-plate receive spikes 9 arranged to engage the base-flange 7, and similarhcles v19 at the other end serve idly. Spike-holes 20 receive spikes 9 arranged to engage the base-flange 8, and similar spike-holes'21 lie idly beneath the 'base flange 7.

Thus arranged the spikes 9 introduced through the holes 18 secure the rail to the tie, with the lip 14 overlapping the baseflange 7, and those in the holes 20 hold the base-flange 8 to the tie, with the lip 15 separated a little distance from the base-flange 8. In this condition the roller 13 is introduced through the recess 17 and forced down to engage its corrugations with the edge of the base-flange 8 and with the vertical face of the ridge 12.

A creeping movement of the rail moves the roller beneath the lip 15 sufficiently to prevent its escape through the recess and the same movement insures its frictional grip upon the rail.

The lip 14 serves usefully in holding the base-flange 7 against lifting movements but the dual arrangement is intended more particularly to permit the tie-plate to be reversed endwise when the vertical face of the ridge 12 has become worn by the action thereon of the roller 13. Such reversal locates the lip 15 upon the base-flange 7 and presents the unworn vertical faceof the ridge 11 to the action of'the roller 13. This shifting of, tie-plate brings the previously idle spike- holes 19 and 21 "into position for service with the base- flanges 7 and 8 by the reintroduction of the spikes 9 and the anticreeping action of the roller 13 proceeds as before.

The tie-plate in the flat condition with its ridges 11 and 12 is produced by rolling, and

the spike-holes and the lips 14 and 15 are produced by punching, slitting and bending operations in suitable dies, all of which are simple and may be performed economically;

- base-flange of said rail, a ridge on said plate lying adjacent to and separated from the inner base-flange of said rail, an overhanging lip formed by folding a portion of said tie-plate upon said ridge, and an engaging rolling member interposed between said ridge and inner base-flange and adapted to lie beneath said lip, the latter having a notch in its edge for the introduction of said rolling member.

2. In an anticreeping device, a tie-plate adapted to support a rail, ridges on said plate one of which is adapted to lie against the outer base-flange of said rail and serve as an abutment therefor, the other of said ridges adapted to lie adjacent to the inner base-flange of said rail and serve as an en gaging surface for a rolling member, and an overhanging lip on each end of said plate, formed by folding a portion of said tieplate upon its adjacent ridge, and 'one of said lips arranged ,to lie upon the outer base-flange, and the other of said lips arranged to project toward the inner base flange above said rolling member.

3. In an anticreeping device, a tie-plate adapted to support a rail, ridges on. said plate one of which is adapted to lie against the outeirbasefiange of said rail and serve as an abutment therefor, the other of said ridges adapted to lie adjacentto the inner base-flange of said rail and serve as an engaging surface for a rolling'member, and an overhanging lip on each end of said plate, formed by folding a portion of said tieplate upon its adjacent ridge, one of said lips arranged to lie upon the outer base flange, and the other of said lips arranged to project toward the inner base-flange above said rolling member, said tie-plate having spike holes therein arranged to permit its reversal and present either of said ridges in position. to-coact with said rolling member and said inner base-flange.

In testimony that I claim the invention above set forth, I aiiix my signature hereto.
