all whom t may concern.'

Be it known that I, Zen OIl the United States, residing at Chicago, inthe county ofv Cook and State of 5 Illinois, have invented new and useful Improvements in Rail Anchors,y of which the following is a specification.

My invention'relates to devices for preventing@ the longitudinal creep of railway rails, these devices being commonly called rail anchors, anti-Creepers, or rail stays.

One of the principal objectsot the invention is toprovide a rail anchor of simple and compact construction which will Amaintain a reliable hold on the rail, as vagainst the tiendency of the device to vibration or other disturbing influences, and

which may be veryquickly and conveniently put in place on the rail or removed therefrom, if occasion requires. i'

A further Object is to provide a rail anchor which can be used `with rails havingr somewhat different rail base contours, particularly with. rails having base flanges which vary in thickness. lt iswellrknown thatrails'of different mikes, evenwhen of the sameweight per linear unit, differ somewhat inthe 'dimensions and contours of.

their bases. Rails ot the same make sometimes have slight diiiierences due to the wearinfrof the rolls employed in manufacturing them. K.

Bly invention contemplates rail anchor a part et which is adapted to extend around and moved transversely on'the rail base in application thereto. anda further object of the invention is to provide, in an anchor ot this sort. means associated with the rail base whereby the angularity of thesurface fecting the practical efficiency of the device.`

POOR, a citi` become loosened byV upon which one portion of such transversely i The invention consists in the novel -arrangements and constructions to be; hereinafter described and claimed torcarrying out the above stated objects and such other ob- .jetts as will appear from the followingdesc-ription. f

The invention is illustrated in apoertain preferred embodiment in the accompanying drawings, wherein:

Figure 1 is a side elevation of a rail an- Chor, embodyingv the principles A,oif my invention. e .f f

Figure 2 is a perspective view o' a tapered. block which is used to vprovide a surface oi" increased angularity with respect to the bottom face pf the rail for one portion ofthe transversely movable memberl to bear upon;

Figure 3 is an end elevation, on a reduced scale, of the device shown as applied tothe rail and in position against one of the ties supporting the same; i p

Figure 4 is a. view, similar to Fi g. l, illustrating modiication; and Y Figure 5 is a perspective view`ot ythe tapered blo'-k shown in Fig. 4.

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

Reterring Erst to Figs. l to 2,-inclusive. l0 designates a railroad rail and l1 one of the cross ties on which. theJ rail is supported.. The rail shown .in Fig. 'l isotthe standard American type. the ton surfaces ofthe base flanges eachl'reinp: straight and 'formed at an of approximately 13 degrees to the bottom ot the base thereof. l

The rail anchor comprises a. body member adapted to extend under and `around the base ianges 12 ot the rail, designated i@jeneralljf hv the reference character and a tapered lblock 14 for provi:lin`,Y a surface for one portion of the body member'to bear upon which surface is oi' ygreater angularity with Yrespect to the bottomv face of the rail "han that of the upper surfacel of ythe portion ot the rail upon which the block 14 bears. Preferably the block isplaced on .top of one of the base lianges l2 or'V the rail and may relative .to lthe body memberY or the blockma'y be providedwith twoV depending lugs i 16 which are spaced apart and are adaptedto hook over the edge ofthe base flange. If desired both the groove and the lugs may be used.v

The body member 13 is preferably constructed of slightly resilient material and as follows: The extremities of the body member are bent over to form jaws 17 'and'18, respectively, these jawsfbeing formed so that the -jaw 18 is approximatelytwice as long as the jaw 17, and its open portion 19 issomelwhat wider than that of the jaw 1,7. Intermediate its ends, and preferably nearer the jaw 17 than the jaw 18, the body member is bent upwardly so 20 which is adapted to bear against the bottom surface of the rail base. When the body member ris thus constructed the proportions and shape'of the

jaws

17 and 18 seat 2O when the device is not applied to the rail, Iare Vsuch that if thatfthe surfaces 1,7va

the top'slur'faces of the right-,hand flange 12 and theblock 14, thetop surface of the seat 20 will be somewhat above the plane of vthe bottom of the rail base in other words, in applying the device to the rail, the seat 20 has to be forced awayfrom

thejaws

17 and 18, that is downwardly intol a lower plane. The engagements of the anchor with the rail base are such that the body of the anchor is distorted and under a strain when applied to the' rail.`

jaw.

, strain as the jaw 17 is The extremity ofthe jaw 18 is preferably bent so as `to provide a shoulder 18". Movement of the body member transversely of the rail, in the direction'to placeit under a strain, causes the edge of the rail engaged by the jaw 18 to seat behind the shoulder 18b `formed on vthe under surface ofy the ber in that direction is resisted by the body member Jbeing placed under an increasing forced `further up thetapered bearing surfaceof the block 14. Movement in the opposite direction, or baaltward, is resistedbecause the vangularity of thebearing surface 18, formed on the un- Vderzsurfaceof the -the bottom face oftherail. is greater than .that `of thefsurface 18a.

The .bloclr is `placedin position on the base flange as shown in Fig. 1. The jaw-18 `the jaw lugs 16. ber to return to its as to form .a seatl Further movement of the body mem-` .ofapproxi'mately and 14 n tively, to the .bottom .of the base thereof.

.tion of applying the vdevice is completed by driving the jaw 17 upon the block 14 by meansI of a sledge-hammer or t-he like, the final position of the body member being 4substantially as shown in full lines in F 1. The jaw the body the rail 17 rides in the groove- 15 as member is moved transversely onto base and the vvertical portion of 17 engagezs the inner faces of the The tendency of the body memoriginal shape results `in an extremely Vstrong gripping vaction on the rail base, which isr sufficient to hold the ,device in position onV the rail against vibration or other disturbing influences. Backward movement of the body member on the rail vbase is resisted by vthe shoulder 18b beinginfront of and engaged by the edge of the rail base. The vents the rail from creepingin the direction from the anchor toward the tie against which the anchor bears, thatis tosay toward the right in F ig. 3. y

The device is of simple and compact construction and may be very quickly applied to or removed from the rail. Another advantage of the device is that it may be used on rails, thebases of which have somewhat different contours. The jaws are of suicient length to take care of slight differences in width of a given rail base. The tapered block provides a surface for of the body member to bea-r upon whichsurface is of greater angularity with respect to the bottom face of the rail than that of the upper face of the flange upon which the block bears which adds to the take-up of the device and permits of morevvariation in the rail base contour and in the manufacture of the body member. In other words, with the takeupA block, there maybe considerable variation in the thickness of the .rail base .andin tbe relative positions of the

jaws

17 and 18 with respect to the seat portion .20.

.without 'affectingtheeticiency of the device togrip the base of the rail.

lullig. 4l, have shown` therlevice .as applied to rail 21 which is ofthe standard British type, the topsurfaces 22 and 23.01: the Vbase 4tlangesaf't beingformed at angles degrees,` respec- Tfn el and V5 l-phave. illustrated va :modified form of tapered block to provide an enseat20 bears aga-inst device effectively preone portion gaging or 'bearing surface of greater anguto the upper face of the tween either one of the jaws jacent flange,

of a British type of raih The bottom of the blockQ is formed to fit the top surfaces of the base Aflanges of the rail. TheV block preferably extends inwardly on the flange Q4 and abuts against the vertical web of the rail. The block preferably is formed with a groove`26 and lugs 27 which are engaged by the jaw 17 to prevent longitudinal movement of the block on the rail base.

So far as I am aware, I am the first in the art to provide for the use of a take-up block such as thatabove described, interposed beof `a device of the type shown and the upper face of the adthe block being so arranged that, upon a movement of the 'body and jaws transversely with respect to the rail and with respect. to the block, the device is caused to tighten about the rail, either by reason of a differential action at the opposite sides of the rail, or otherwise. `While I have shown the

jaws

17 and 18 of different length, with reference to the position of the bearing portions of the jaws with respect to the position of the intermediate seat 20 understood that I do not wish to be restricted to this particular arrangement eX cept so far as the claims arel specifically so limited, While the wedgey 14 isv shown in vengagement with the flange at the left in Fig. 1, with the thicker portion of the wedge disposed 'adjacent to the vertical web ofv the rail, it will be understood that I do not wish to' be restricted-to this feature except so far as the same is specifically claimed, inasmuch as it is evident that the important characteristic ofthe operation of the wedge is that the jaw underneath which the wedge is interposed shall be moved upwardly with respect adjacent flange as the `device is moved from its preliminary applied position to the operative vtightened position.
