ANTICREEPEB FOR RAILS.

Specieation of Letters Patent.

Patented May 30, 1911.

Application led February 9, 1909. Serial No. 476,923.

To all whom it may concern:

Be it known that I, FREDERICK Snenxe, a

vcitizen of the United States, and` resident of Chicago, in the county of Cookvand State of Illinois, have invented ertain new and.

creeping tendency or thrust of the rails tol ward the tie adjacent to which it is placed; the device being so constructed' thatany tendency of the rail to creep will increase the purchase or bite of the device on the base of the rail; the nature of. the device thus obviating the necessity of any bolts and the like, as will more fully hereinafter appear.

In the drawing Figure 1 is a perspective view of my improved anticreeper shown applied to a portion of a rail and taking against a portion of tie shown. Fig. 2 shows the device in elevation, the side that lies adjacent to the tie being shown. Fig. 3 is a vertical sectional view taken on the line 3 3 of Fig. 2.

In the drawing, A, represents a portion -of a tie to which the rail B issecured in the usual manner. Engaging the base of the 'l rail, is my improved anticreeper C, which is applied to the rail on the side of the tie or sleeper from which the creeping tendency arises, in `other words on the side of the tie from which the train approaches the device. This device C, which is made of suitable metal, comprises the cross-piece or body-portion a, which is adapted to lie flat against the bottom of the base of the rail as shown in Fig. 1; integral with said portion a, is an inclined depending member composed of the downwardly extending ribs or depending portions I), b, b, the lower ends of which may all be integrally united by the b earlng or connecting piece c. These ribs b, depend from the body portion a in a sloping manner, away from the direction in which the train is to approach the tie A, so that the lower ends of the ribs, or, in the particularv form illustrated in the drawing, the vertically extending piece c, will be forced against the tie as illustrated in Fig. 1, some little Vdistance beneath the top of the tie. Ex!

tending outwardly from the body portion a andlbeyond the side ribs b, are the hookshaped gripping members or jaws .(l, d, which are preferably so formed as to pro- 'vide a flat surface or face at'l the points e which conform to and take onto the flanges of the rail-base; these faces e being made to incline as shown in Fig. 2, to more readily adapt themselves to the rail-base. In forming the ljaws or gripping-members as shown and described, a slight shoulder is formed at the .juncture of the fiat surface and the ribs which will prevent side slipping of the device on the rail-base. Furthermore, in bowing out the gripping-members as shown, a greater distance is had between the bowed portions than exists between the points of the members. Sufficient play is thereby given between the curved portion of one jaw and the point of the opposite jaw, to perinit of the device being placed on the rail at the desired point without necessitating the anticreepers being slid onto the rail before it is fastened in place. This enables the placing of the anticrcepers at any point on rails that have been put in place, as is apparent. The gripping members or jaws d, d, extend of course slightly abovethe horizontal plane of body-portion a, the distance being sutlicient to accommodate the'flange of the rail as shown in Fig. 1. For the sake of strength, the gripping members or jaws may be provided with the reinforcing ribs f and g, substantially at right angles to each other, which also form the shoulders before referred to.

It is apparent that with the train approaching from the right hand side of Fig.

1, the side of the tie adjacent which the anticreeping device is placed, any pressure or strain on the rail B will be transmitted to cross-piece or member a, which will press the bearing member or piece c more firmly against the tie. The pressure o f member c against vthe -side of the tie tends'to practically make' the body-portion a act as a fulcrum point against the bottom of the rail and thereby increase or strengthen the bite or grip of jaws or gripping-members Z on the upper surface of the flanges of the rail-base.

It is evident that in forming the anti- Creeper in substantially the angular shape illustrated, wherein the one point is in advance of theothers, towitz-the one that takes against the bottom of the rail, and receives the strain, the hold on thev rail is strengthened at the very moment when the tendency, on the part of the rail, tocreep arises.

I have shown and described a particular type of device, but it is apparent that certain modifications in construction -may be made without departing from the spirit of my invention.

Having thus described my invention, what I wish to claim ent, is

1. An anticreeper for rails comprising a body-portion adapted to take against the rail-bottom, a pair of gripping-members integral with said body-portion and extending into a plane slightly above the horizontal plane of the body-portion, and a depending member integral with said body-portion, the depending-member and gripping-members being in substantially the same vertical plane but to one side of the vertical plane of the body-portion.

2. An anticreeper for rails, comprising a single member adapted to take about the base of the rail and grip over the base-ange and bear against the side of the tie, the portion taking beneath the rail being in advance of the portion gripping the flange and the portion bearing against the tie.

3. An anticreeper for rails, comprising a single member having a' body-portion, adapted to extend transversely beneath the `railbase, gripping-members, and a dependingmember, said body-portion being arranged in advance of the other members and acting as a fulcrum when strain or pressure is transmitted-thereto, whereby the grip of the gripping-members Von the base-fianges is strengthened.

4c. An anticreeper for rails, comprising aJ single member, one portion of which takesbeneath the rail-base, a second portion takes about the opposite edges of the rail-base, and a third portion takes against the side of a tie, the second and third portions being in the same plane to oneside of the perpendicular plane of the first portion, the relaand secure by Letters Patne direction tends to force the first menf tioned portion against the bottom of the rail-base and give a tilting motion to said member thereby increasing the grip ofthe first andsecond mentioned portions on. the rail-base'.

5. An anticreeper for rails, comprising a body-portion adapted to take against' the bottom-of the rail, gripping-members extending out from the ends of the body-portion and adapted to take over the baseflanges, said gripping-members being provided with reinforcing ribs substantially at right angles to each other, and depending sloping ribs whose lower ends are united to provi-de a substantially vertically extending 'surface to take against the side of a tie, said surface lying in a vertical plane to one side of the vertical plane in which the body-portion lies.

6. An. anticreeper for rails, comprising a body-portion adapted to' take beneath the rail, gripping-members integral with the sides thereof and formed to permit of the same being placed on the rail at the desired point, and a depending-member adapted to take against the tie, said body-portion being arranged in advance of the other members.

7. An anticreeper for rails, comprising a body-portion adapted to take against the bottom of the rail, gripping-members integral with said body-portion, said members being so formed that the distance between the members at a oint intermediate of their ends and the bo y-portion is greater than the distance between'the. tips of said members, and a depending member adapted to take against the tie, said body-portion being arranged in advance of the other members and acting as a fulcrum point about which-the other members move.

8. An anticreeper for rails, comprising a body-portion adapted to take against the bottom of the rail, a pair of gripping-members, each of w-hich is provided 'with a shoulder adapted to take against the edge of the baseflange to prevent transverse movement, and a depending-member adapted to take against the tie, said body-portion being'in advance of the other members.

9. An anticree er for rails comprising a cross-piece or body-member, a pair of gripping-members curving outwardly from and to the rear of said body-member and extending into a horizontal plane above that of the body-member, and a bearing-member eX- tending rearwardly of and sloping downwardly from the body-member.

10. An anticreeper for rails comprising a fulcrum surface adapted to take against the bottom of the rail, gripping members indownwardly and rearwardly from the fultegral with the ends of the fulcrum surface, Crum-surface to engage the side of a tie behaving their gripping surface to one side low the top thereof.
