'This invention pertains to an improved and novel one piece railway rail anchor or anticreeper especially designed to be fixedly secured to the base portion of railway track rails in engagement with stationary parts of the road bed, and is adapted to effectually prevent longitudinal movement or displacement of the track rails during the travel of the heavy rolling stock thereover.

The main object of the invention is to provide a simple, durable, economical, practical and thoroughly eflicient rail anchor possessing maximum strength, and which when properly applied will serve to effectively resist all creeping tendency of the track rail.

Another object of the invention is to provide a rail anchor formed of a single piece of suitable spring sheet steel, which under all conditions rigidly and tightly grip and lock the track rail against creeping longitudinally toward an adjacent cross-tie of the road bed.

A further object of the invention is to so construct my novel anchor that the sheet spring steel will be so folded as to produce a central longitudinal wall adapted to grip the lower face of the track rail base with intense pressure entirely across the said face, and the greater the tendency of the track rail to move longitudinally, caused by the enormous pressure of the rolling stock passing thereover, the greater will be the intensity of the clamping and gripping power imparted to the anchor with relation to the track rail to which it is applied.

The foregoing and such other objects as may appear from the ensuing description are attained by the construction, formation, location and combination of the several parts hereinafter more fully described, illustrated in the accompanying drawings, and particularly pointed out in the several claims appended hereto, it being understood that slight changes in the precise form, proportions and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings forming a part of this specification it will be seen that:

Figure 1 is a side elevation of the improved rail anchor embodying my invention, showing it fixedly secured to the base of a track rail, with said track rail shown in cross-section.

Figure 2 is a plan View thereof, showing a portion of a track rail and cross-tie broken away.

Figure 3 is an end view of the rail anchor 55 secured to a track rail, showing in side elevation a portion of said rail broken away and a crosstie in cross-section.

Figure 4 is an enlarged perspective of the anchor disconnected from the track rail.

Figure 5 is a side elevation thereof.

Figure 6 is a cross-section taken in the plane of the dotted lines 6-6, Fig. 5, looking in the direction of the arrow, and

Figure '7 is a cross-section taken in the plane of the dotted lines 7"I, Fig. 5, looking in the 455 direction of the arrow.

In the embodiment of my invention as illustrated, it will be seen that the numeral 1 designates a railway track rail, the said rail having a tendency to move longitudinally or creep, when subjected to the excessive pressure and strain caused by the travel of the heavy rolling stock thereover.

My novel and improved rail anchor may be formed in any suitable or desirable manner, but 7 is preferably formed from a single piece of flat high grade sheet spring steel of the desired and required dimensions, said single piece of steel being so compressed by suitable dies as to produce a formation having three separate, distinct and spaced

upright walls

2, 3 and 4, each of said walls extending throughout the length of said anchor, with the central wall 3, extending slightly above the Walls 2 and 4 disposed at each side of the said central wall, and at one end portion of the anchor is formed a pair of comparatively large overlapping jaw members 5, adapted to firmly and tightly grip the upper surface of the flanged base of the track rail, wlnle at the opposite end of the anchor is disposed a pair of small gripping members 6, adapted to have a clamping and gripping contact with the edge of the rail base and slightly overlapping the upper surface of the flanged base portion of the track rail.

By reference to Fig. 2 of the drawings it will be seen that the anchor is fixedly secured to the track rail, said track rail being fixedly secured. to a cross-tie 5, while Fig. 3 shows an end view of the rail anchor secured to the track with the rail seated upon the cross-tie 5 with the outer face of the inner wall 4 of the anchor resting in contact with the said cross-tie, and between the inner face of each of the walls 2 and l and the central wall 3 the channel formations 7 are formed by the spaced formation constituting the inner face of the anchor, the same formation causing a channel 8 to be' formed centrally in the lower face of the anchor.

It will be readily perceived that by the special and particular construction of my novel anchor the larger overhanging clamping ends of the anchor may be'easily placed by hand on the 5 flanged base portion of the track rail at one side thereof, with the other end of the anchor resting in contact with the lower face of the track rail base, then by striking the left hand end of the anchor with a suitable sledge the anchor will be forced across the said lower face of the rail until the smaller clamping end shall pass beyond the edge of the rail base, when it will immediately snap upwardly and tightly grip the other side of said rail base.

The anchor may be detached from the track rail when desired by the use of a suitable tool adapted to pry or force off the slightly overlap ping smaller jaw member to a position beneath the rail base, when by striking the right hand end portion thereof one or more blows with a sledge it will be readily removed from the rail.

It will be evident that, since the central wall 3 normally extends slightly above the other walls of the anchor, the said wall 3 will rest in contact with the lower face of the rail base, and that the forcing of the anchor across the rail base and into its properly fixed position said base by the use of a sledge will tend to depress said central wall, thereby simultaneously distending each of the side walls 2 and 4, the inner wall being caused to rest tightly in contact with the cross-tie 9, hence, when any tendency of the rail to move longitudinally occurs, such movement will immediately impart more gripping power to the gripping parts of the anchor, thereby successfully and practically preventing any and all creeping action or longitudinal movement of the track rail to which the anchor is properly secured.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

l. A rail anchor formed of a single piece so as to produce a formation composed of three upright spaced walls extending throughout the length of said anchor, and a clamping jaw at each end thereof.

2. A rail anchor of the character described, comprising a single piece of steel formed with three spaced upright walls with the central wall extending slightly above the other walls, and a clamping jaw member formed at each end of said anchor.

3. A rail anchor formed from a single piece of sheet spring steel having three separate upright walls spaced apart with the central wall extending above each of the other walls, a large overlapping jaw member formed at one end thereof, and a small jaw member formed at its other end.

4. A rail anchor of the character described, comprising a single piece of spring steel, said single piece being so pressed as to produce a formation having three upright walls spaced apart, each of said walls extending throughout the entire length of the anchor, a large overlapping rail clamping member formed at one end, and a small rail clamping member formed at the other end.

5. A rail anchor formed of a single piece of sheet steel pressed into a folded formation having three upright Walls, with the central wall extended above the other walls, and a rail clamping member at each end thereof.

6. A rail anchor of the character described, comprising a folded formation having three upright walls with the central wall extended above each of the other walls, a channel formed between each side wall and central wall within the anchor, and a rail clamping member formed at each end of the anchor.

7. A rail anchor of the character described, comprising a formation composed of three upright longitudinally disposed walls parallel with 105 each other with the central wall disposed above each of the other walls, and a rail clamping member at each end of the said anchor.

8. A rail anchor of the character described, comprising a folder formation composed of three 110 longitudinally disposed upright walls with the central wall disposed above each of the other walls, a channel formed within the anchor between the central wall and each side wall, a centrally disposed channel formed in the outer 115 face of the anchor, and a rail clamping member formed at each end.

9. A rail anchor of the character described, comprising three longitudinally disposed upright Walls parallel with each other, the central wall extending above each of the other walls in contact with the lower face of the rail base, a longitudinal channel formed between the central wall and each side wall, a centrally disposed channel formed in the lower face of the anchor, and a rail clamping member formed at each end portion of the said anchor.
