RAILWAY-RAIL ANCHOR Application filed January 9, 1930. Serial No. 419,619.

-This invention pertains to a novel and improved one piece rail anchor especially designed to be attached to the base portion of railway track rails, and adapted to engage with stationary parts of the railway road bed for the purpose of preventing longitudinal displacement or creeping of the track rails which tends to occur during the travel of the heavy rolling stock thereover.

Themain object of the invention is to provide a novel, simple, durable, reliable and economical rail anchor, or anticreeper, possessing a maximum of strength, which when properly applied will eflectively resist to a minimum the creeping tendency of the railroad track rail.

Another object of the invention is to so construct my improved rail anchor that any tendency of the rail to creep will tend to swing the anchor about its fulcrum against the crosstie and thereby cause the anchor to intensify its'gripping action in contact with the track rail.

A further object of the invention is to provide a novel and improved rail anchor formed from a single piece of high grade spring sheet steel, preferably heat treated steel, which will under all conditions rigidly secure the rail and prevent its creeping action toward an adjacent cross-tie.

The foregoing and such other objects as may appear from the ensuing description are accomplished by the construction, arrangement, location and combination of the several parts hereinafter more fully described, illustrated in the accompanying drawings, and particularly pointed out'in the 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 novel device embodying my invention applied to a track rail, showing the track rail in crosssection and in side elevation a railway crosstie broken away.

Figure 2 is a plan view of the same showing the track rail'broken away. i

Figure 3 is a side elevation showing the device detached from the track rail.. Figure 4 is a plan of the device such as is shown in Fig. 3, and

Figure 5 is an end view thereof.

In the drawings as illustrated, it will be seen that Fig. 1 shows my novel rail anchor applied to the base of a standard traclrv rail 1, the said anchor, as an entirety, being designated by the letter B, and is formed from a high grade of spring sheet steel possessing the desired thickness and dimensions to furnish a maximum of strength, by pressing or stamping the sheet in suitable dies and at the upper part of the same, at one side thereof, is formed an overhanging clamping aw memher 2 and at its other side or end portion is formed a clamping or gripping member 3, said members being adapted to-tightly grip and clamp the baseportion of the track rail at each side thereof, respectively.

The lower end portion of the body 4 of the anchor B is formed with outwardly pressed or bent portions intermediate its'ends at 5 and 6, said portion being disposed in opposite directions, each of said portions 5 and 6, bein adapted to rest against and contact with a cross-tie 7, dependent upon which side of the track rail to which the anchor is prop erly and securely applied, since the said anchor is so constructed that it may be as easily and readily secured to either side of the base of the track rail. 7

The upper portion ofthe body 4 is formed intermediate its ends with extensions 8 and 9 upwardly and outwardly inclined in opposite directions, said extensions being adapted to exert an intense gripping and clamping action against the lower face of the rail base when the anchor shall havebeen properly and fixedly applied to the rail base, since beneath or below each of the extensions '8 and'9 the body portion is cut out to form slotted portions 10 and 11.

In applying the anchor to the base of the track rail it is simply necessary to place it by hand on one side of the rail base with its jaw member 2 overlapping the upper surface of the rail base with the lower face of the base of the rail resting on the upper face of the extension 8, then by driving it endwise from the left hand end of the device, as shown in the drawings, with a suitable sledge, such as is usually employed for like purposes, until the inner face of the clamping member 3 passes the opposite edge of the rail base when the clamping member 3 will immediately snap upwardly and tightly clamp the other side of the rail base, all of the parts in contact with the base, being under intense gripping and clamping action with said base.

This device may be easily removed or detached from the rail base by striking the upper face of theclamping member 3 downwardly and then driving it off from the right hand end of the anchor, as will be readily understood. 7

Itwill be perceived that when the anchor shall have been fixedly secured to the rail base in themanner shown in Figs. 1 and 2, the outwardly extended portion 5 of the body will rest in contact with the cross-tie, hence the greater the transverse pressure and strain caused by the travel of the rolling stock over the track rail, the greater the tendency to impart a twisting or canting movement to the anchor, thus intensifying the gripping action of all of theparts of the anchor that are in contact with the rail.

It will be readily obvious that by the construction of anchor hereinbefore described that when the anchor has been fixedly applied to the rail base the extensions 8 and 9 will have an intense gripping contact with the lower face of the rail and any tendency of the rail to creep imparts a corresponding tendency to rock the anchor about its fulcrum against the. tie and that such tendency to rock or cant causes the parts to more intensely grip'and clamp the upper and lower surfaces respectively, of the rail base. Any tendency, therefore of the rail to creep immediately results inthe anchor being more tightly clamped to the rail base,

and more forcibly resists any creeping action thereof.

It will be readily evident that this particu- 'lar formation of anchor including the lower body portion formation contributes in greatly strengthening the anchor, thus preventing breakage, springing or dislodgement of the anchor when properly applied in fixed position.

It will be understood that this type of anchor may be applied from either sideof the track rail, and that it may be readily detached from the rail and repeatedly used, thereby increasing its longevity.

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

1. A one-piece rail anchor adapted to be fixedly secured to the rail base, comprising a body portion adapted to contact with said rail base and formed with oppositely disposed curved extensions formed at the lowermost end of said body portion, and a clamping member formed at each end portion of said anchor. p 1 I 2. A one-piece rail anchor adapted to be secured to the rail base, comprising a rail clamping member at each end portion thereof, a body portion adaptedto contact with the rail base and oppositely disposed laterally extended curved portions formed at the lowermost end of the said body portion and extending to each of'its outer ends.

3. A rail anchor formed of spring sheet steel with a clamping member at each end adapted to engage each side of a rail base, and intermediately disposed upwardly and outwardly extended portions for clamping the lower face of the rail.

4. A rail anchor formed with a clamping member at each 7 end portion thereof for clamping each side of a rail base, and a body portion, said body portion being formed intermediate its ends at its upper portion with a plurality of upwardly and outwardly extended portions.

5. A rail anchor formed of spring sheet steel with a clamping member at each end portion thereof adapted to engage a railbase, and a body portion having its upper end por-,, tion formed intermediate its ends with a pair of outwardly and upwardly extended portions, said body being slotted below said extended portions.

6. A rail anchor of the character described, comprising a sheet of spring steel formedv with a clamping member at each end portion thereof adapted to clamp the'base of a rail, a body formed at its upper end portion with two upwardly and outwardly disposed por tions intermediate its ends and slotted portions beneath said disposed portions, and oppositely disposed extended portions formed at the lower end portion of said body.

7. A rail anchor formed from sheet spring steel, comprising a clamping member at each end thereof for engaging each side of a rail base, a body formed at its upper end portion with an upwardly and outwardly inclined member intermediate its ends, said body being slotted below said inclined member, and oppositely disposed laterally extended portions formed at the lower end of said body.
