RAIL-ANCHOB..

Specification of Letters Patent.

Patented Aug. 1, 1916.

Application filed December 31, 1912. Serial No. 739,441`

To all `whom it rmay concern:

Be it known that I, JOHN M. Scor'r, a citizen of the United States, residing at Racine, in the county of Racine and State of Wisconsin, have invented certain new and useful Improvements in Rail-Anchors, of which the following is a specification.

My invention relates to the class of track devices, known variously as rail anchors, rail stays, or anti-Creepers, which have for their purpose tocheck the tendency of railroad rails to creep longitudinally in the direction of travel of the trains.

In one type of device of this class the device consists of clamping members extending around and engaging the base flanges of the rail which have a wedging relation one with another whereby the clamping action of the device on the rail is effected. For example, a device of this sort which has been used to a certain extent is composed of a bar extending under the rail provided with jaws on opposite ends and of a key or wedge which is driven in between one of the base flanges of the rail and one of said jaws, the other jaw extending around and gripping the opposite base flange. An anti-creeping device of this sort has the advantage of being strong, light, simple and cheap to manufacture, but has this serious disadvantage in that the wedge or key frequently becomes loose or backs out due to the vibration of the railV under the trains, and to other Causes.

The principal object of my present invention is to provide an expedient for locking together the relatively movable parts of an anti-creeping device of this general type which will be effective, will add little or nothing to the cost of the device, and which, incidentally, will permit the relatively movable parts of the device to be disengaged with little trouble so that the device may be removed from the rail if occasion requires.

The improvement constituting the invention is shown in connection with a device consisting of a bar adapted to extend under the base of the rail at the anchor provided with integrally formed jaws and of a longitudinally slotted key which is driven in between one of the base flanges of the rail and one of the jaws of the first named member. It will be understood, however, that the improvement is applicable to the other constructions of the same general type.

The invention is illustrated in the accompanying drawing wherein- Figure 1 shows, in elevation, a. preferred form of the invention applied to a railroad rail which appears in section. Fig. .2 is a plan view of the parts shown in Fig. l; Fig. 3, a sectional view taken on line 3 3 of Fig. 2; Figs. 4, 5 and G, an end view, a top view and an edge view, respectively, of the key or wedge member, and Fig. 7, a fragmentary plan view illustrating particularly the expedient employed for locking the wedge in its operative position.

Like characters of reference designate like parts in the several figures of the drawing.

Referring to the drawing, A designates a railroad rail and B one of the ties on which it is supported. The anti-creeping device consists of a bar C, preferably of malleable iron, formed at one end with a jaw D adapted to engage one of the base flanges of the rail A and at the other end with a jaw E larger than the jaw D. A key or wedge` member F is driven in between the jaw E and the adjacent base flange of rail A, the jaw E being preferably formed so that it stands oblique to the edge of the rail base and the key F being formed with the tapered slot G for the edge of the base flange. The bar C is provided with the usual tie abutting flange H or other suitable means for holding the anti-creeping device in a fixed position with respect'to the road bed.

The upper surface of the key F is formed with one or more grooves or indentations I providing a shoulder or shoulders J. The jaw E terminates in a relatively thin\flange K which overlies the grooved surface of the key F. After the key has been driven into place the portion of the edge of the flange K above one of the grooves I is indented or offset by any suitable means, for example, a chisel and hammer, into the groove. This may be done very easily and expeditiously and does not require the use of any tools except those that are ordinarily carried by the track crew. With the edge of the jaw offset into the slot of the key the key is obviously locked against any retrograde movement. However, if the anti-creeping device has to be removed from the rails this can be radily done by the key backward. The metal of the jaw will yield sufficiently to permit this to be done.

A rail anchor comprising a bar adapted to extend under the rail base provided at one end with a jaw adapted to engage one of the base flanges of the rail and at the other end with a. larger jaw disposed obliquelylwith respect to the rail, a. key adapted to be driven into said lastfnamed jaw formed on its inner edge with a tapered slot in which the adjacent edge of the base Harige is received; said key being formed on its upper surface with a transverse groove and the edge of said inclosing jaw having a smooth Hange extending across und adapted to be off-set into said groove.
