RAILWAY-RAIL ANCHOR.

Application filed. September 27, 1928. Serial No. 308,643.

This invention relates to a new and improved one piece rail anchor or anti-creeper especially designed to be secured to the base portion of railway track rails'and in engagement with stationary parts of the road bed for the purpose of preventing longitudinal displacement of the track rails during the travel of the heavy rolling stock thereover.

The prime object of the invention is to .rovide a simple, durable and economical rail anchor or anti-creeper, which when properly applied will effectively resist all creeping tendency of the track rail.

Another object of the invention is to provide a novel rail anchor formed from a single piece of sheet spring steel, such as heat treated steel, which will unc or all conditions rigidly and securely lock a rail against creeping toward an adjacent crosstic.

A further object of the invention is to so construct my novel anchor that any tendency of the rail to creep will compress the body portion of the anchor, thus causing each set of gripping jaws to more intensely grip and clamp the base of the track rail to which it is attached.

The foregoing and such other objects as may appear from the ensuing description are accomplished by the construction, arrangement, formation, location and combination of the several parts herelnafter more fully described, illustrated in the accompanying drawings, and particularly pointed out in the claims appended hereto, it being understood that slight changes 1n the precise form, proportions and minor details of construction may be resorted to without departing from the spirit or sacr1- ilcing 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 perspectrve of the novel device embodying my invention.

Fig. 2 is a side elevation of the same.

Fig. 3 is an end elevation taken from the left hand end of the anchor.

Fig. 4 is a plan view of the same, and

Fig. 5 is a plan of the steel blank before being folded and formed into the rail an choring device.

In the embodiment of my invention as illustrated, it will be seen that the novel rail anchor consists of a single piece of sheet spring steel having a depending body portion comprising two horizontally disposed upright members 1, said members being con nected together by a centrally disposed depending curved, or rounded, portion 3, the upper edges '4, 4, of the body portion being adapted to contact with the lower face of the base portion of a track rail, as will be readily understood. One end of each of the members 1 and 2 is provided with an overlapping corrugated jaw member 5 adapted to. overlap and tightly grip the upper inclined faces at one side of the track rail base, while the opposite end of each of said mem bers l and 2 is provided with a slightly overlapping jaw 6, adapted to grip the 0pposite edge of the rail base and to tightly clamp against the upper inclined face of the oposite side of the track rail, having a laterally and outwardly extended portion 8 be tween the overlapping portion and the u per edge 4 of the members 1 and 2.

It will be observed that the gripping jaw members 5 are provided with a corrugated formation adapted to materially add to their strength and rigidity.

My improved rail anchor may be formed in any suitable or desirable manner, but is preferably formed of a single piece of (hot pressed) high grade sheet spring steel of the desired or required dimensions, as clearly shown in the drawings, Figure 5 of which, showing a blank from which the completed anchor is properly formed, the body portion of said blank being bent or folded along its horizontal central portion, said blank being so compressed as to form widely separated portions 9 at one side of its vertical center and narrowed portions 10 at the opposite side of its central portion, and gradually narrowed from its widened portion into the narrowed portion substantially as shown in the drawings, Figures 1 and 4.

It will be readily understood that this particular type of anchor is formed from a single piece of high grade spring steel and it is first applied by hand endwise on the base of the rail with the clamping jaws 5 mounted upon the upper inclined surface of one side of the rail base, and with the upper edges of the jaws G in contact with the lower face of the rail base, and it is then driven endwise from its left hand end beneath the rail base by means of a suitable sledge or maul until the jaws 6, which are under an upward tension against the lower face of the rail base, are caused to pass beyond the edge of the base of the rail, when said aws 6 will immediately spring upwardly and clamp over the edge of the rail base, thereby causing both the 5 and 6 to impart an intense gripping contact with the rail base when the anchor shall have been completely adjusted to its proper operative position on the base of the track rail.

The anchor may be removed by the use of a suitable tool adaped to pry or force o'l't' the slightly. overlapping jaws 6 to a position below the rail base, when by striking the right hand end portion one or more sharp blows with a sledge it will readily become detached from the rail.

it will beperceived that by the construction of anchor hereinbetore described that while the anchor is being driven endwise on the rail base the jaws 6 are under a stron upward tension in contact with the lo; face of the base of the rail, hen e when the said jaws are forced beyond the edge of the nailbase they will immediately spring upwardly into contact with and rip said edge, and that owing to the specific construction of jthis single piecespring metal device, any tendency of the track rail to creep under intense strain will cause the portion in contact with the tie to be pressed outwardly and thus impart an inward movement to each end portion thereof, thus causing the clamping jaws at each end to more intensely grip each side of the rail base, thereby ar resting any and all tendency of the creeping action of the rail.

Having thus described my invention, what I claim and ent is:

, 1. A single piece rail anchor comprising a body portion widened at one end and narrowed at its opposite end, each end having a pair of gripping jaws, and a rounded de pending member connecting the body portion intermediate its ends.

2. A single piece rail anchor comprising a body portion consisting of two upright desire to secure by Letters Fatmembers wide ed apart at one end and nar- A single piece rail anchor comprising a body port on formed with two upr ght nienib a centrally disposed member 'd'e pendmg below said upright members, adapted to connect upright members, a pair of gripping;- jaws at one end of the anchor, pair of gripping jaws at the opposite ends of the anchor, and an outwardly extended portion formed between the jaws and the upper edge of the body port-ion.

5. A single piece rail anchor comprising a body portion formed with two upright members, a centrally disposed lepending rounded member for connecting the upright members, a pair of corrugaten jaws formed at one end, and a pair of clamping jaws at its opposite end.
