Specification of Letters Patent.

RAIL-ANCHOR.

Patented oet. 4J, 1921.

Application filed .Tune 3, 1919. .Serial No. 301,428.

`of Illinois, have invented certain new and useful Improvements in Rail-Anchors, of which the following is a specification.

My invention relates to improvements in that type of devices for preventing the creeping of railway rails, which comprises a yoke provided at opposite ends with jaws for engaging the rail base, and a key or wedge adapted t0 clamp the jaws of the yoke into gripping engagement with the rail, either the yoke or the wedge being provided with a tie abutting member.

The object of my invention is to provide a device of this character which will be of highest efficiency, simple of design, easy of application and securely attached to the rail at all times regardless of whether or not the tie abutment is in engagement with the tie. i e Y A further obj ect of my invention is to pro vide a novel wedge for anti-Creepers provided with a` corrugated surface adapted to bite into V`the base ofthe rail and securely hold it against movement in the yoke regardless of the particular form of yoke employed. These and such other objects as may hereinafter appear are attained by my device, certain preferred forms of which are disclosed in the accompanying drawingsin Figure 1 is a planl view of a device embodying the principles 'of my invention as applied to a rail,

Fig. 2is an end elevational view of the device shownin Fig. 1,

Fig. 46 isa perspective view of the wedge shown inthe preceding figures, l FigV is a cross-sectional view taken on line 7 -7 of Fig. 8 showing a modified form of wedge,- Fig. 8 is an end elevational view of the yoke and the modified form of wedgeas applied tothe base of a rail,

Fig. 10 is a detail view showing the serrated end of the wedge in locking engagement with the edge of the yoke, and

Fig. 11 is a detail view offthe end of a sheetv metal yoke adapted to engage the serrated end of the wedge.-

Like characters of reference designate like parts in the several views.

Referring rst to Figs. 1 to 6 inclusive, 12 indicates a railway rail and 13 a tie or other abutment which may kbe engaged by the depending tie abutment member 14 shown in these views as an integral part of the yoke 15. The yoke is preferably formed with integral jaws 16 and 17, the jaws being slightly bendable or resilient. The jaws are preferably spaced far enough apart and provided with sufficiently deep undercuts to permit the yoke to be slipped over and seated on the Vbase of the rail. The ends of the jaws may be smooth but I prefer to form them with teeth extending transverselyrwith respect to the rail, as shown more clearly in Fig. 3, so as to obtainbetter gripping action. The jaws 16 and 17 are each formed with the respective perforations 18 and 19 adapted to receive a tapered key 'or wedge 20. The wedge 20 is adapted to be driven through the jaws of the yoke and is inter-V posed between the body of the yoke and the base of the rail. The wedge is provided with a plurality of sharp ridges or'corrugations 21 which extend longitudinally of the wedge and which are adapted to bite into the base of the rail when the wedge is driven Y. home. Preferably the corrugations are formed near the middle of the top surface of the wedge so that the central portion of the base of the rail will be gripped when the wedge is driven home. The wedge may be secured in the yoke by upsetting or bending. the small end up or down around the edge of the yoke, orrby any other suitable means, such as a cotter pin, zor the lock-nut y22 threaded on the end of the wedge Aso that the nut 22.

YIn Figs. 7 to 9 inclusive, I have shown the principles of my invention embodtions.

wedge, extending as they do transversely I of the rail, `bite into the base thereof and the wedge is somewhat longer than the yoke,l

oneendthereof being provided with a depending apron 24 which is adapted to abut against the tie.

Obviously, however, the toothed interlocking structure between wedge and yoke may lbe used with the tieV abutment on any convenient part of the structure.v l

When the serrated end is used on the wedge it may.l interlock with the yoke by snappingover the straight edge of the yoke as shown in Fig. 7 in which the serrated end vof the suiiiciently resilient wedge has normally a slight downward bend; or the yoke may have a slightly raised edge as at 25 in fFig. 10 over whichtheserrated edge of fthe wedge is forced to locking position.

When Va sheet metal yoke is used as in "my Patent 1-,248,790,'the end of the resilient yoke "may be normally formed with a 'slightly raised edge -26 to engage the serrated end, ofthe wedge. asin Fig. 11, in which event it is'not necessary that the wedge be fresilient. j

From the drawings and the foregoing de- Y Vseription it will be obvious that the wedge maybe applied to yokes of various descrip- Thev corrugations formed on the effectively preventloosen'ing of the wedge by any'longitudinal movement ofthe rail. It is obvious that various departures may be ymade from fthe exact structure shown without departing from the spirit of my invention which contemplates such changes in form( rl f l.

It will be understood that I do not wish Vto be restricted to the specific form of wedge member shown in the drawings in. which the wedge member is given a continuous even taper from end to end, the important vfeature being` that it has a wedging'engagement with respect'to the jaws 16 and 17 and that the lcorrugati'ons 21 are forced into wedge memberis forcedinto position.
