RAIL-ANCHOR.

Specification of Letters Patent.

Patented Feb. 15, 19211.

To all whom it may concern:

Be it known that I, HAROLD G. WARE, a citizen of the United States, residing at Park Ridge, in the county of 'Cook and 5 State of Illinois, have invented certain new and useful Improvements in Rail-Anchors, of which the following is a specification.

My invention relates to devices for pre venting the longitudinal creeping movement commonly called anticreepers, rail stays or rail anchors.

The principal object of this invention is I to improve upon the type of rail anchor disclosed in the patent to D. F. and D. L. Vaughn, No. 1,021,387, granted March 26, 1912. This type of anchor consists of a shoe member adapted to bear againsta tie and to engage one edge of the base of the rail to which the device is applied, and a torsional spring yoke which extends under the rail base, engages the shoe and the opposite edge of the rail base, and is strained, when in its operative position. The present invention improves upon this type of anchor by providing a shoe member which may be more conveniently and economically manufactured than the malleable casting which forms the shoe member of the patented anchor, and one which can be made considerably lighter than the shoe of the patent, without the sacrificing of the necessary strength and rigidity required in devices of this character. The minimizing of weight in devices of this class is an important consideration, as rail anchors are manufactured in large quantities, sold at a relatively low rate per article, and frequently have to be shipped to points remote from the place of manufacture, so that the cost of transportation is a substantial factor in the cost of the articles to the railroad company.

The invention consists in the novel arrangements, constructions, and combination of parts, hereinafter described and claimed for carrying out the above stated objects, and such other objects as may appear from the following description.

The invention is illustrated in the accompanying drawings, wherein- Figure 1 is a plan view of a rail anchor constructed in accordance with my invention, and shown applied to a rail;

the spring yoke member of the anchor before being applied to the rail;

Fig. 9 is a view illustrating the form of blanks from which shoe members of the above type are formed.

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

Referrin to the drawings, 25 indicates a railroad rail, and 26 one of the cross ties on which the rail is supported. The rail anchor, as illustrated in the drawings, consists of a shoe '27 and a spring yoke 28. The yoke is the usual form of spring yoke now used in connection with the Vaughn anchor patented in the patent above referred to. It is made'from a flat piece of steel which is given a torsional set and is formed at one end with a notch 29 to engage one edge of the rail base and at the other with an upstanding lug 30 to engage the shoe member 27, the lip 31 by which the upper edge of the notch 29 is defined being bent forwardly toward the tie (having reference to the position of application of the anchor to the rail) as shown in Fig. 1.

The shoe is formed of sheet metal which is cut from a blank having the contour indicated in Fig. 5. The blank, after being cut to this shape, is bent along the lines a, I), c, to provide a rail base engaging jaw formed of an upper lip 32 and a lower lip 33, the latter of which preferably lies horizontally under the rail base, a tie abutting flange 34:, and a connecting web 35. The blank is out so that a notch 36 is provided between the rear edge 37 of the connecting web and the forward edge 38 of the lip 33. This notch is designed to receive the lug end. of the spring yoke and is preferably slightly wider than the thickness of the material from which the spring yoke is formed. The lower edge of the spring yoke 18 thinned edge 38 of the lip 33. The width of the i down to provide a shoulder 39. This shoulder engages a projection 40 which is formed on the edge 37 of the connecting web 35. Preferably the portion of the anchor designated 41, which connects the upper lip .32 and the lower lip 33, and the connecting web 35, is pressed out to form a boss 42. The purpose of this is to increase the width of the shoe at this place so that shoes so formed may be used interchangeably with the malleable iron shoe, heretofore employed in anchors of this type, without change of the dimensions of the spring yokes.

To apply the device to the'rail, the shoe member is fitted over one edge of the rail base with its tie-abutting flange bearing against the tie. The yoke member'is hooked over the other edge of the rail base, and is bent, was to straighten out its torsional set sufliciently to permit the end of the yoke having lug 30 to be raised into notch 36 in the shoe, with shoulder 39 on the yoke engaging projection 40 on the shoe, and the upper edge of that portion of the spring yoke which extends under the rail base in interlocking engagement with the shoe member and bearing against the forward notch 36 is preferably just suflicient to permit the upper edge of the yoke member to be readily inserted to its interlocking position with clearance suflicient to permit the yoke member to assume a diagonal position across the rail base. The torsional strain to whlch the spring yoke is subjected keeps the anchor in close engagement with the rail. The yoke is prevented from becoming disengaged from the shoe because of the bearing of the shoulder 39 on the lug 40 and the engagement of the upper edge of the yoke with the forward edge 38 of the lip 33.

In Fi 7 to 9 inclusive I have shown a modi ed form of anchor in which the lower lip 33 of the shoe member 27 is tapered toward its end as indicated at 41 so as to permit the jaw end 29. of the spring yoke 28 to move rearwardly with the rail a greater distance than is possible with the form of lip shown in Figs. 1 to 6, inclusive, without danger of distorting or breaking the yoke. When the yoke 28 assumes the diagonal position across the rail as indicated at A in Fig. 7 of the drawings, for example, during a retrograde movement of the rail when the shoe member is frozen in the ballast of the road bed or otherwise held in arelatively fixed position, the anchor device increases its grip on,the rail base so as to resist further rear-ward movement of the rail.

The shoe member 27* is preferably made from" a blank 42 having a configuration which permits one blank to nest with another as indicated in Fig. 9. A plurality defined on one side by of blanks of this form, it will be noted, may be cut from one sheet of metal without any appreciable loss of material. In other respects, the spring yoke and shoe member of the above modification may be the same as that shown and described in connection with Figs. 1 to 6 inclusive of the drawings.

This application is a continuation in part of my co-pending application, Serial No. 306,342, filed June 24, 1919.
