ful Improvements in Rail-Anchors, of which the following is a specification.

My invention relates to devices for preventing the longitudinal creep o-f railway rails, these devices being commonly called rail ancho-rs, anti-Creepers, or rail stays.

One of the principal objects of the invention is to provide a rail anchor of simple and compact construction which will maintain a reliable hold on the rail, as against the tendency of the device to become loosened by vibration or other disturbing 1nfluences, and which may be very quickly and conveniently put in place on the rail or removed therefrom, if occasion requires.

A further object is to pro-vide a rail anchor which can be used with rails having somewhat different rail base contours, particularly with rails having base flanges which vary in thickness. It is well known that rails of different makes, even when of the same weight per linear unit, differ someF what in the dimensions and contours of their bases. Rails of the same make sometimes have slight differences due tothe wearing of thefrolls employed in manufacturing them.

My invention contemplates a rail anchor a part of which is adapted to extend around andA be moved transversely on the rail base in applica-tion thereto, and a further object of the invention is to provide, in'an anchor of' this sort, means associated with the rail base whereby the angularity o-f the surface upon which one portion of 'such transversely movable part .bears is greater than that of that portion of the rail base with which said. means is .associated whereby said transverse movement results in a tightening of the anchor on. the rail and more `variation 1n the rail base contour 1s permitted without affecting the practical eiii.- ciency ofthe device. The invention consists in the novel ar rangements and constructions to be hereinafter described and claimed for carrying out' the above sta-ted objects and suchother objects as will appear from the following 'descriptio-n. Y

Tlieinvention is illustrated in a certain preferred embodiment in the accompanyin drawings whereinf Figure 1 is .a side elevation of a rail anchor, embodying the principles of my in-V vention; Fig. 2 is a perspective view of a tapered block which is used to provide a surface of increased angularity for one portion of the transversely movable member tobear upon;

Fig. 3 is an end elevation, ona reduced scale, of the device shown as applied to the rail and in position against one of the ties supporting the same;

Fig. 4 is a view, similar to Fig. 1 illustrating a modification; and

Fig. 5 is a perspective view block shown in Fig. 4.-

-Like charac-ters of reference designate like parts in the several figures of the drawings.

Referring first to Figs. 1 to 3, inclusive, 10 designates a railroad rail and ll one of the cross ties on which therail is supported. The rail shown in Fig. 1 is of the standard American type, the top surfaces of the base flanges each being straight and formed at an angle of approximately 13 degrees to the bottom o-f the base thereof.

The rail anchor comprises a body member adapted to extend under and around the base ianges 12 of the rail, designated generally by the reference character 13 and a tapered. block 1li for providing a. surface for one portion of the body member to bear upon which surface is of greater angularity than that of the rail base upon which thev block 14 bears. Preferably the block is placed on top of one of thebase flanges 12 of the -rail and may extend backwardly and abut against the vertical web of the rail, as shown in. Fig. 1. The block ,is preferably provided with means to prevent it from slipping longitudinally on the rail base.. The upper surface of the block may be fo-rmed so as to provide a groove 15 adapted to receive one jaw of the body member or the block may be of the tapered pro-vided with two depending lugs 16 which 'bent over to form jaws 1,7 and 18, respectively, theseWjaws-fbeiiig formed soY thatsthe adapted to bear against the bottom surfacel of the rail base. When the b ody member is thus'constructed the proportions and shape of the jaws 17 and 18 relative to the seat20 when the device is not applied to the rail, are such that if the device be placed so that the surfaces 17a and 18a thereof coincide, respectively, With the top surfaces of the righthand flange 1 2 and the block 14, the top surface of the seat 20 will be somewhat above the plane of the bottom of the rail base, in other words, in applying the device. to the rail, the seat 20 has to be forced away from the jaws 17 and 18, that is downwardly into 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.

The extremity of the jaw 18 is preferably b ent so as to provide a shoulder 18". Move'- ment of the body member'transversely of the rail, in the direction to place it under a strain, causes the edges of the rail engaged by the jaw 18 to seat behind the shoulder 18b formed on the under surface of the jaw. Further movement of the body member in that direction is resisted by the body member being'placed under an increasing strain as the j aw 17 is forced further up the tapered bearing surface of the block 14. Movement in the opposite direction, or backward, is

resisted because the angularity of the bearing surface 18C, formed on the under surface of the jaw 18, is greater than that of the surface 18a. y

The device is applied tothe rail as follows:

rIhe block 14 is placed in position on the base flange as shown in Fig. 1. 'The aw 18 is booked over the right hand flange of the 'rail base and the body member is then swung upwardly until the seat 20 bears against the bottom of the rail base and the beveled corner 17" of the jaw 17 engages thetapered surface of the block 14, as shown inthe dotted lines in Fig. 1. It will be seen that the jaw 17 cannot be moved7 from the position shown in dotted lines inFig. 1, further upon the tapered block 14 without distortion of the body member'. The operation of ape plying the device is completed by driving t jaw 17 upon the block 14 by means of a Sledge-hammer or the like, the final position of the body member being substantially as shown in full lines in, Fig. 1. The jaw 17 rides in the groove 15 as the body member is moved transversely onto the rail base and the vertical portion of the jaw17 engages the inner facesr of the lugs 16. The tendency of the body member to return to its original ness of the rail base and inthe relative posithat of the base flange with which it is assoshape results in an extremely strong gripping action on the rail base, which 1s sufficient to hold thedevice in position on the rail against vibration or other disturbing influences. Backward movement of the body member on the rail base is resisted by the shoulder 18" being in front of and engaged by the edge of the' rail base. The devicel effectively prevents the rail from creeping forwardly, that is 'to say, in the direction from the anchor toward the tie against which the anchor bears.

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, the bases of which have somewhat different contours. The 'aws are of sufficientlength to take care o ,slight differencesin widthof a given rail base. The tapered block provides a surface for one portion of l the body member to bear upon which surface is of greater angularity than that of the rail base upon which the block bears which adds to the take-up of the device and permits of more variation in the rail base contour and in the manufacture of the body member. In other Words, with the take-up block, there may be considerable variation in the thick tions of the jaws 17 and 18 with respect to the seat portion 20, without affecting the elficieicy ofthe device to grip the base of 'the rai In Fig. .4I have shown the device as applied to a rail 21 which is of the standard British type, the top surfaces 22 and 23 of the base fianges 24 being formed at angles of approximately 6 and 14 degrees, respectively, to the bottom of the base thereof. In

-ing or bearing surface of greater angularity than either of those of the base flange of a British type of rail. The bottom of the block 25 is formed to fitthe top surfaces of the base flange of the rail. The block preferably extends backwardly on the flange 24- 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.
