RAIL ANCHOR.

Application filed May 10,

The invention relates to rail anchors and seeks to provide a one-piece anchor of simple, cheap construction, which can be readily applied to or removed from the rail base by means of hammer blows, and having a spring grip upon the rail base the tension of which is increased by the creeping tendency of the rail.

The invention consists of the improved construction hereinafter set forth, illustrated in its preferred forms in the accompanying drawing and more particularly pointed out in the appended claims.

In the drawing:

Figs. 1 and 2 are plan views of slightly modified forms of the improved anchor applied to the rail base;

. Fig. 3 is a side elevation thereof;

Fig. 4 is a similar view illustrating the manner of applying the anchor to the rail;

Fig. 5 is an end elevation with the parts of the anchor in the position shown inFigs. 1 and 3;

Fig. 6 is a plan view illustrating a modification, and

Fig. 7 is an end elevation of such modification.

The improved anchor is formed of a resilient steel bar which is preferably round in cross section. In its preferred forms, it comprises a cross member orbar 10 which is arranged to extend beneath the rail base 11 from side to side thereof and bear against its lower surface. Preferably, as shown,

' the cross bar 10 is slightly bowed so that its central portion is spaced slightly from the rail base and its end portions or and b bear or seat against the lower surface of. the rail base adjacent its edges.

The end of the cross bar outside and adjacent its seating portion a merges directly into a closed, depending spring loop 12 formed by bending the bar downwardly and inwardly and then upwardly and outwardly, and this loop terminates in a substantially vertical, C-shaped jaw 13 having upper and lower members 0 and cl and which receives one of the rail base flanges. The opposite free end of the cross bar is upturned to provide a lug or shoulder 14 which is arranged to engage the edge of the other rail base flange. Preferably, as shown, the lug or shoulder 14L is provided with a lip e which, when the anchor is in position on the rail,

slightly overlaps the edge ofthe base flange, and the rail engaging seat f of the lug or shoulder 14 may, if desired, be provided with teeth or edges for slightly indenting the rail.

The lower jaw member (Z and the adjacent end of the cross bar 10, which in eflect form the overlapping ends of the spring loop 12, are arranged closely adjacent and side by side and preferably the lower jaw member is disposed in front of the adjacent end of the cross bar. The loop 12 is elongated transversely of the rail and the greater portion of it is arranged to be located below the rail flange engaged by the jaw 13 with the outer end of the loop projecting laterally slightly beyond the jaw. Preferably as shown, the loop is inclined forwardly from the lower jaw member d and the cross bar 10 and its lower, forwardly bowed portion 5/ constitutes a foot or abutment for engaging the side of the tie '15 at a point spaced some distance below its upper face.

In applying the anchor to the rail base, it is first placed in the position shown in Fig. 1. Then, by means of hammer blows applied to the outer end of the loop, it is forced onto the rail base and as soon as the shoulder 14 passes beyond the edge of the adjacent railbase flange, it snaps up into the position shown in Figs. 1 and 2. The jaw 13 and shoulder 14 are so disposed that in the application of the anchor to the rail in the manner described, a tensionis developed in the spring loop which causes these parts to securely grip the edges of the opposite rail base flanges. The cross bar 10 may extend substantially at right angles to the rail as shown in Fig. 1', or be slightly inclined as shown in Fig. 2, to bring the rail engaging portions. of the lug and jaw in alignment transversely of the rail. The anchor may be applied to the rail base with the forwardly bowed portion of the loop engaging the tie, or it may be applied to the rail base at some distance from the tie and then driven forwardly into engagement therewith.

The jaw 13 has a loose fit on the rail base flange. That is to say, the upper and lower jaw members 0 and cl are so spaced as to facilitate the application of the anchor to rail base flanges varying somewhat in thickness. Also, with the anchor free of the rail and the jaw members disposed in the same vertical plane, the lower jaw nember d is disposed below the rail-engagmg portion or seat a of the cross bar as shown in Fig.-

i, and the vertical distance between the seating portion a and the upper jaw member 0 is somewhat less thanthe thickness of the rail base for which the anchor is designed. Hence, when the anchor is forced into position onto the rail, one of the base flanges is gripped between the upper jaw member 0 and the adjacent end or seating portion a of the cross bar and the engagement of the seating portion witn. the lower face of the rail tends to tilt the jaw toward the cross bar as shown in Fig. 5, and thereby causes its upper and lower members to bear or press upon the adjacent rail base flange. That is to say, notwithstanding the loose fit of the jaw upon the base flange, the lower jaw member and the adjacentend of the cross bar engage the underside of the base flange at points adjacent and on opposite sides of a vertical plane extending transversely of the rail and through. the rail-engaging seat of the upper jaw member. This arrangement holds the anchor firmly in position with the spring loop extending forwardly of the jaw and cross bar and with its lower forwardly bowed portion engaging the tie some distance below its upper face to hold the rail-gripping parts of the anchor well away from the tie and with the entire anchor spaced well away from any tie plate, such as indicated at 16. Hence, creeping of the rail cannot exert any pressure on the tie 4 plate that mightloosen the rail spikes.

The construction shown in Figs. 6 and 7 issimilar to the forms shown in Figs. 1 to 5 inclusive, except that the jaw member 13 is arranged in rear of the adjacent end of the cross bar 10 and the jaw 13 is tilted forwardly on the base flange instead of rearwardly. In both forms, creeping pressure will tend to straighten the forwardly bowed lower portion of the loop and will also tend to cramp the anchor on the rail base so that the grip of the anchor is thereby increased.

Changes may be made in the details set forth without departure from the scope of the appended claims.
