RAIL-ANCHOR.

Specification of Letters Patent.

Paienlcd'Feb. 27, .1917.

Application flied August 24. 1914. Serial No. 858.230.

-cago, in the county of Cook and State of Illinois, have invented certain new and use ful Improvements in RaihAnchors, of which the follmving is a specification.

llly invention relates to a device forpreventing the longitudinal creep of railroad rails, these devices being commonly called rail anchors, rail stays or anti-creepers, and particularly to a device in which one or preferably both of the elements constituting the railclainp are resilient and are strained by the application of the device to the rail, so as to resist a retrograde movement as between the elements, tending to loosen the grip of the device on the rail and hence diminish its holding power. A rail anchor is subjected not only to the forward stress caused by the creeping tendency of the rail, but also to vibration and to certain forces which operate at times in the direction contrary to the forward creep of the rail, tendingto more the device away from the tie against which it is abutting and to loosen the grip of the parts between themselves and upon the rail. Unequal expansion and contraction of the rail and parts of the anchor, due to tempera'tnre changes, also tend to destroy, unless checked, the holding power of the device.

The primary object of my invention is to provide a rail anchor comprising a plurality of co-engaging elements which together grip the rail, fpr example, the base flange thereof, and are so constructed and arranged that the forward creep of the rail produces a positive wed ing action between the ele ments, where W said tendency to creep is self checked, one or both of the elements being resilient and strained by application of the device .to the rail so that vibration and shrinkage of metal due to temperature changes is absorbed and any tendency which the parts of the device may have toward a loosening or retrograde relative movement is prevented.

A further object of the in ventionis to provide a rail anchor which will be inexpensive to manufacture, strong and durable and, at the same time, light in weight. -Weight is an important consideration as well in the cost of tr:ms n)rtat|on as Ill cost of manufacture.

The invention is illust1-=- oil in certain pre-' ferred embodiments in the accompanying drawings, whercin Figure l is a sectional elevation, of a rail anchor constructed in accordance with the invention shown as applied to a rail, the view looking toward the tie against which the device is abutted.

Fig. 2 is a side elevation of the tie abutting element of the device, shown in the position which it assumesbefore the other element, the yoke, is put in place;

Fig. 11, a view, in. perspective, of the tie abutting element in this form of the invention.

Like characters of reference designate like parts in the several figures of the drawings.

Referring to the drawings, A designates a. railroa1l 1'ail and B one of the cross ties on which the rail is supported.

The rail anchor illustrated in Figs. 1 to 6 inclusive, consists of two co-engaging elements. :1 tie abutting element C and a. yoke I). The tie abutting element C is in the form of a plate adapted to bear against the cross tie B and provided with 11.- tongue E preferably formed at its outer end with an upward bend F. This element is preferably made of sheet metal, sheet steel, for example. and the tongue is formed with a tapered depression (I eonstituting in ell'eeta wedge.

lhe yoke element I) is adapted to extend around the base of the rail and the tongue I: lying under'said rail base. -'l'he yoke is preferably formed at the middle with a bend or indentation II and at one end with grooves I for the applieation ot' a elaw bar.

ln applying the deviee to a rail. the tie abutting mem er t is plaeed under the rail base against the tie. as shown in Fig. 2. The yoke is slipped under the. rail and around the tongue I) so that it assumes the position shown in Fig. (3. The reressed end of the yoke is then engaged by a elaw bar .1; and is raised and at the same time l'orred toward the rail into the position shown in Figs. 1 and I). This bends the part ot the tongue beyond or backward of the wedge t as best shown in Fig. I). The yoke may then be driven up the wedge (l toward the tie as 't':\ as may be neeessary to obtain a seeure hold on the rail 'ith the parts oli the deviee in this position a wedge (i opposes the further movement ot the yoke toward the tim against whieh. it will he understood. the other element bears. forward rreep ot' the 'ail. whieh is imparted to the yoke I). produees a positive wedging aetion between the elements of the anehor that inereases the grip of the deviee on the rail so that the ereeping movement is self eheeked. ()n the other hand. any retrograde movel'neut of the yoke I) is eheeked by the downward slope of the outer end of the tongue I) resulting from the bending of the tongue. The elastie relation between the two elements absorbs vibration and slight shrinkages of metal due to tempe 'ature ehanges. ll] order to facilitate the applieation of the yoke. the end provided with the claw bar reeess I may be formed-with a ram surfare K whieh rides over the edge ol the rail base. .\s a matter of l'aet. it would be possibl to apply the devieewithout the use of :relaw bar. in whieh ease the reeess I might. be omitted.

In I igs. T to 1. 'inelusive. I have shown an author consisting preferably. though not neeessarily. of two parts ('onstrneted like thoseot' the anehor just d-eserihed exeept that the yoke member is modified so that one of its jaws will take a erainping or biting hold on the rail and the other a \vedging grip when the deviee is in operative position. 'hen so eonstrueted the yoke will move forwardly with the rail when the latter ereeps. It is funetiona-lly part of the rail. Fig. 7 shows the position of the yoke when tirst applied to the rail. Fig. H shows the elements of the anchor in their operative position. The yoke designated I) is formed at one end with a bend (I so that when the yoke is adjusted to its position on the rail base the jaw on this end takes the desired eramping grip on the lt-l L'(' of the rail base. may' e formed with a bearing 1/ tor the under surt'a're ot' the opposite edge of the rail base. .\.s the surfare rl" of the yoke has the slope of the upper face of the rail base the transverse movement of the yoke in adjusting it to its tinal position gives it a wedging grip' on the edge of the ail base at this 'ide. I

ln Figs. 10 aml 1t I-have shown a rail anehor eonstrneted upon the same principles but in whieh the tie abutting member is strlietnrally ditt'erent. Ihe yoke member here designated I) may be substantially the will! a the yoke member I heretofore deseribed. The tie abutting member I, is made of rolled tapered stoek so that the tongue M is thiekest near the tie abutting plate'and thins down toward its extremities. 'hen the deviee is applied to the rail. the thin t'lexihle end of the tongue is bent and the same result obtained as in the other form of the invention; that is. the forward movement ot' the yoke is eheeked by a positive wedging aetion between the yoke-and the" :tongue M while the movement of the yoke away from the tie is eherked by the bent end of the tongue.

While I have shown and deseribed the invention in eertain preferred emhmlilnents. further moditieations might be made without departure from theprineiples of the invention. 'lheretore I do not wish to-be understood as limiting the invention to the partieular eonstruetions. arrangements and deviees shown and deserilied exeept so far as the same are speeitieally made limitations in eertain of the elaims herein.
