RAIL-ANCHOR.

Specification of Letters Patent.

Patented June 17, tom.

Application filed January 24, 1916. Serial No. 73,894.

' provements in Bail-Anchors, of which the following is a specification.

My invention relates to devices for preventing the longitudinal creep of a railroad rail; and the principal objectof the invention is to provide a device which will ef fectually grip the rail and hold it and at the same time'be simple in construction and easily and rapidly applied.

A further object of the invention is to; provide a rail anchor in which the tendencyof the parts tobecome loosened from vibratlon or other causes 1s checked and prevented.

A further object of the invention is provide a rail anchor which will be inexpensive to manufacture, strong and durable and,

' at the same time, light inweight. Weight is Fifi an important consideration both in the cost of manufacture and in the cost of transportation.

One embodiment of the invention is shown in the accompanying drawings, in which:

Figure 1 is a side elevation showing the device in operative position on the rail.

Fig. 2 isa sectional view at the plane indicated by the broken line X X in Fig. 1.

Fig. 3 is a sectional view at the plane indicated by the line X X in Fig. 1 showing a position of the parts when the device is be ing applied to the rail.

Similar letters refer to similar parts throughout the several views; r

In the drawings A designates a portion of a railroad cross tie, which forms a stationary part of the road bed, which supports the rail and over which the rail tends to creep under the well known conditions ;jand B a railroad rail supported thereon. usual construction con'iprising a head C a vertical web D anda ba'se flange E. Engaged with the rail B and the cross tie A is the transverse member F of the rail anchor and engaged with the transverse member F or the rail anchor and with the head C and base flange E of the rail B, is the vertical member G. of the rail anchor. The transverse member F is constructed with a jaw I-I arran ed to embrace and grip one side of the The rail B is of" the opposite side of the rail. The end of the memberFopposite to the jaw H is provided with a portion K adapted to engage a face which this surface M joins one ofthe side walls of the aperture I may be rounded as at N. The vertical member G is provided at its upper end with a portion presenting surface 0 adapted to engage with the under side of the rail head C and at the lower end with a portion P adapted to engage with the surface M of the member F. Connecting the portion-P with .the body of the member G- is a portion Q arranged to traverse the aper-. ture I in the member F and a portion R, which in the operative position of the device engages the upper surface of the base flange E of the rail B at the side opposite to the jaw H of the member F. The member Gr may be so formed that in the initial condition of G the portion R is slightly bowed or curved as illustrated in Fig. 3, and the rela tion of the portions P Q and R is such that when the member is placed in the position illustrated in Fig. 3 with the surface 0 of the member G about to engage with the under surface of the rail head C and the the member Gmay be provided by turning the end portion of the material of which is constructed as illustrated and when this is done the end T presents a convenient striking face. i j

The rail anchor is applied to the rail by placing the member F With the jaw II in en gagement with one edge of the base flange E of the rail B, driving the member F transversely upon the rail until a position is reached exposing sufficiently, the aperture I at the other side of the rail base flange E topermit the member G to be inserted in the aperture I and passed to the position shown, in Fig. 3., In this position the ,end or the portion]? of the member G will em gage the surface M of the member F and the portion R of the member G will engage the upper corner of the rail baseflangeE while the surface O of member G will justbegin to engage the under surface of the rail head C. To get the parts into the operative position shown in Figs. 1 and 2 the upper portion of the member G is forced transversely of the rail from the position illustrated in Fig. 3 either by striking the face T with a hammer to drive it or by applyingforceto .theupperpart of the member G in some other suitabl manner. The engagement of the upper-end of-the member-LG vwith the under: surface of the railhead '0 produces a "camming actionzwhich, during this forced I transverse movement of. the upperaend of the member G, forces this portion of the mem ber Gr downward. The portion R of the member Gispiv oted on the upper corner of the rail base flange E and the first effect of the downward movement of the upper portion of the memberG is to cause the portion Q tobearupon the transverse member F at N and exert a transverse pull upon the mem ber F and to cause the portion 5P of the member G, engaging the surface M of the member F at S to press upwardly upon the the. device.

The member G is preferably constructed of reslhent material and, while the member G is deformed under the stresses to which it s 1 snbwcted during and after application,

its resiliency will cause it to exert, indefinltely, the pressures upon the transverse member F and the rail B.

From the.form of the member-G and the forces to whichit is subjected it will be apparent'that, when the parts are in their operative position, the resiliency or spring action of the member G-wlll tend to cause 1t in its unstressed condition and that-this .will

tend to cause the portion of themember G which is vertical or nearly .so and .wedged in-betwee1 the undersurface of thehead C and theupper surface of-the.base flange E to move upwardly. The engagement .ofthe .SlllffLCGlO of the member G with the under surface of ;the -ra1l,,head ,C prevents this movement,andithe parts are in this manner effectually locked in position ,upon the ;rail

and prevented from being accidentally dismember F. There is exerted in this wayhfilodged or=loosened upon the rail.

both a transverse pull and an upward pressure of the member G upon the transverse member'F. These pressures increase as the parts are forced into position and, in the operative position of the parts illustrated in Figs. '1 and 2, the portion P of'the member G engages and presses upwardly upon the urface M of the member-F for practically itswhole length and the portion Q engages and presses outwardly upon the member F atN.

The forces which are applied to Gto ,cause the portions P and Q, to'press vertically andtra nsversely upon'the member F are, as stated above,the result of the coaction of the upper end ofthe member (r and ,the under surface ,of the rail head C and they' are transmitted through the portion R ofthemen'iber G which is pivoted or fulcrumed upon the upper corner of the rail 'base flange E. As the downward force upon ,the upper end of the member G -in creases the portion It of the member G is deflected or bent downward into contact with the upper surface 0ftl 1e'rail;base

flange E and in ,thefinal operative position liange 'E is distributed over the entire surface of contact of the port-ionR of the men].-

from the principles Should it-be desired to remove the anticreeper :from the ra1l 1t 1s necessary to forelbly move the upper portion of1the member .G outward from the rail until the position illustrated in :Fig. 3 is reached. This may be done by driving a wedge in between the upper portion of the meinberGr and the web D of the rail or by applying the 11001 ordinarilyused by :track mechanics for pulling rail spikes betweenithe web D ofitherrail and the upper portion of the memberiGr and prying "the upper portion of G out from :the

' rail;

as limiting-the invention-to the particular construction, arrangement and devices shown and described, except so far as these limitations are specifically set forth in certain of the claims herein. i
