RAIL ANCHOR on ANTICBEEPER.

Specification of Letters Patent.

Patented May 7,1918.

Application filed August 4, 1916. Serial No. 113,126.

To allwhom it may concern:

Be it known that I, LOUIS L. KonAoH, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Rail Anchors or Anticreepers, of which the following is a specification.

' This invention relates to that class of rail anchors which are adapted to be secured in engagement with a railway rail in position to engage a cross-tie or abutment, to prevent the creeping of the rail.

The principal object of the invention is to provide a simple, economical, and efilcient rail anchor or antioreeper for railway rails.

A further object of the invention is to provide a rail anchor or anticreeper having relatively movable clamping jaws adapted to engage a railway rail, with simple and efticientmeans for; securing the jaws firmly in clamping engagement with the rail,.and' adapted to enable the device to be mounted in osition and removed with facility.

ther and further objects of the invention will appear from the following description and claims, and from an inspection of the accompanying drawings which are made a part hereof.

The invention consists in the features, combinations, parts, and details of construction herein described and claimed.

In the accompanying drawings Figure 1 isa plan view of a rail anchor or anticreeper constructed in accordance with my invention and improvements, showing the same secured inoperative position upon a railway rail, and'in engagement with a cross-tie. i I

Fig. 5, an enlarged detail view in elevation of the clamping member shown in Fig. 4:.

Fig. 6, a plan view'in detail of the tieengaging main jaw member, which extends beneath the rail.

and socket member 1, which comprises in its construction a base portion 2, which is adapted to extend beneath and in engagement with the bottom faceof the base 3 of j a railway rail 4, and having an upwardly projectingrigid aw portion 5, integral with the base and adapted to engage one edge of the rail base. 'The main jaw and socket member 1 is also provided with an upwardly projecting rigid jaw portion 6, at the opposite extremity of said main jaw and socket member from that on which the jaw portion 5 is located.- The jaw'portion' 5 has an inwardly extending approximately horizontal flange 7 at its upper extremity which is adapted to extendinward over the adjacent longitudinal edge or margin 8 of the rail base and in engagement with the upper side of the rail base. The jaw portion 6, which is adapted to extend upward on the opposite side of the railfrom that on which the jaw portion 5 is located, is provided with an approximately horizontal inwardly projecting flange or jaw portion 9, which by preference extends inward above the level of the top surface of the adjacent longitudinal margin'or edge of the rail base, so as to provide a space betweenthe railbase and said flange portion, and between the fla'nge portion and the base-2. Thejaw' 6, with its flange portiont) extending inward and approximately horizontally over the baseportion 2, is hollowed out so as to provide a socket ll, having a curved approximately semi-circularupright wall portion 12 facing toward the central portion of the main jaw member land toward the rail when the device is in opera tive position upon a rail. A movable jaw member 13, having a curvedapproximately semi-circular end surface portion 14,- corresponding with and adapted to bear against the curved wall portion 12 of the socket 11, and having a lower shouldered bar-engaging portion 15 which is adapted "I10 to be inserted into position in the socket 11 through slot 16, is movably mounted in said socket 11, in engagement with a securing bar 22. This movable or pivoted jaw member 13 has a rail engaging end surface or jaw portion 17, which is adapted to engage the upright longitudinal edge or face of the rail when the curved end face 14 is seated in engagement with the curved socket Wall portion 12 above described, the portion of the jaw member 13 between the curved end 14 and the inner rail engaging. endor jaw portion 17, being of such length that when the jaw member 13 is in position to extend approximately at right angles with respect to the rail but in slightly oblique relation to the rail, the jaw will fit snugly in engagement with and between the engaged edge of the rail base and the socket wall 12. (See Fig. 1.) It is plain that the movement of the rail engaging or inner movable end of the pivoted jaw member 13 from the position in which the latter is shown in full lines in Fig. 1, to the position in which said jaw member is shown in broken lines in said figure, will tighten the engagement between the jaw member and the base of the rail, and cause the jaw member to bite into, or impinge against,

the rail base with increasing firmness and with an increasing degree of security corresponding with the extent of movement in the direction indicated, or in a direction tending to bring the pivoted jaw member into locking position substantially at right angles with respect to the rail and in clutching engagement with the rail base. The movable or pivoted jaw member 13 is, by preference, provided with a slightly tapered upper endwise projecting wedge portion or flange 18, which is adapted to be wedged firmly in position between the rigid flange 9 of the jaw 6 and the adjacent marginal portion of the rail base by the movement of the jaw member 13 in the direction above indicated.

The main jaw member 1 is provided with atransverse aperture or slot 19, which eX- tends transversely with respect to the rail when the device is in operative position upon a rail. The upright wall portion 20 of this slot is, by preference, slightly oblique with respect to the upright wall portion 21 on the opposite side of the slot, and a transverse securing bar or wedge '22 is inserted in the slot 19 in such position that the side face 23 is in slidable engagement with the adjacent face 24 of the pivoted jaw member 13 while the opposite side face 25 is in slidable engagement with the upright Wall portion. 21 ofthe slot 19, and the side face 23 of the wedge, near the end which is farthest from the pivoted jaw member is at the same time in slidable engagement with the wall portion 20 of the slot. The portion of the slot between the oblique wall portion 27 and the wall 20 is made sufiiciently wide to permit the bar or wedge member 22 to be driven into the slot and in engagement with the wall 20, the pivoted jaw member 13 and the wall 21 and transversely with respect to the device and with respect to the longitudinal center of the rail, to force the pivoted aw member 13 from the position in which it is shown in full lines in Fig. 1 toward the position in whichit is shown in broken lines in said figure, and into secure gripping engagement with the adjacent edge of the rail base. The transverse, but preferably oblique upright side wall 20 of the transverse slot 19 is thus at a slightly oblique angle with respect to the longitudinal center of the transverse locking bar or wedge member 22, when the latter is in position to engage said wall 20, the jaw portion 2 1 of the movable jaw 13 and the wall 21. From the foregoing it is plain that by driving or otherwise forcing the securing bar Or wedge member 22 into the slot transversely with respect to the device and with respectto the longitudinal center of the rail, from the position in which said bar or wedge member 22 is shown in full lines in Fig. 1, to the position in which it is shown in broken lines in said figure, the pivoted or movable jaw member 13 will be forced into secure gripping or clutching engagement with the rail base. and that this result will be obtained whether the securing 'bar or wedge is of equal width throughout its entire length, as shown in Fig. 1, or tapered as shown in Fig. 9. It is therefore practicable to use a metallic bar, which is of equal width throughout its entire length, and which is therefore of much more economical construction than a tapered wedge or bar. It is obvious, however. that a tapered wedge. such as that shown in F g. 9, may be used in lieu of the baror wedge member 22 shown in Fig. 1, if desired, and such a tapered wedge will operate in an efficient manner without materially changing the device in any substantial respect. The tapered wedge 28, as shown in Fig. 9, is adapted to be used in the slot 19 and in lieu of the bar or wedge member 22, with the device constructed as above described andshown, although it is obvious that the wall 20 of the slot19 is not required tobe in oblique relation to the tapered wedge, but may be parallel with the opposite wall 21 of the slot in case the tapered wedge is to be used.

. The main jaw member 1 is provided with a transverse depending rib 29 which is adapted to engage the adjacent upright side face of a cross-tie 30 when the device is in operative position upon a rail; and tapered flanges 31 are provided beneath the opposite side margins of the main jaw memberl,

- or frozen earth which may accumulate beneath or adjacent to the main jaw member to be loosened, so as to prevent injuryto the 7 device or track when the rails expand or contract by reason of changes in temperature. In order that the device may have the maximum strength in proportion" to the weight of material used in its construction the base 2 is provided with strengthening ribs 32 and 33, which are adapted to engage the bottom face of the rail base. e

I claim I 1. In a rail anchor, the combination of a main jaw member having opposite upwardly extending rigid jaw portions one of which is adapted to engage one side of a railway rail, a movable jaw member mounted in ena gagement with the other of said upwardly ex tending rigid jaw portions and with the oppcsite side of the rail, and a wedging member movable transversely with respect to the railway rail and located between and having its opposite sides in engagement with said jaw members and acting to press the movable jaw member in a direction lengthwise of the rail, to secure said jaw members in en-' gagement with the rail.

2. In a rail anchor the combination of a main jaw member having a base portion adapted to extend beneath a railway rail, and having opposite upwardly extending rigid jaw portions one of which is adapted to engage one side of the rail, a movable jaw member mounted in engagement with the other of said upwardly extending rigid jaw portions and adapted to engage the opposite side of the rail, and a wedging member movable transversely with respect to the rail and located between and having its opposite sides in engagement with said jaw members, and adapted to tend to press the movable aw member in a direction length- Conlel 0! this patent may be obtained for wise of the rail, to secure the jaw members in engagement with the railway rail.

3. In a rail anchor, the combination of a.

main jaw member provided with a socket portion and having a rigid upwardly extending jaw portion adapted to engage one side of a railway rail, a movable jaw member mounted in the'socket portion of and .in movable relation to said main jaw memher and adapted to engage the opposite side or the rail, and a securing member movable transversely with respect to the rail and located between and having its opposite sides in engagement with and in movable relation to said jaw members, and adapted to tend to press the movable jaw member in a direction lengthwise of the rail to secure the jaw members in engagement with the rail.

4. In a rail anchor, the combination of a main jaw member, having a plurality of upwardly extending rigid aw portions spaced apart and adapted to admit a railway rail therebetween, one of which upwardly extending jaw portions is adapted to engage one side of the railway rail, a movable railengaging jaw member movably mounted in engagement with the other one of said upwardly extending rigid jaw portions and adapted to extend between said last mentioned jaw portion and the adjacent side of the rail, and a wedging member movable transversely with respect to the rail and located between and in engagement with and in movable relationto said movable jaw member and main jaw member, respectively, and acting to press the movable jaw member in a direction lengthwise of the rail to secure said jaw members in engagement with a I railway rail.
