' RAILWAY-RAIL "ANCHOR Application filed April 3, 1930. Serial No. 441,286.

' This invention pertainsto a novel, new and improved rail anchor especially designed to be secured to the base portion of a railway track rail, and adapted to engage with stationary'parts of the railwayroad bed for the purpose of effectively preventing the longitudinal displacement or creeping action of the track rail which is likely to Occur during the travel of the heavy rolling stock thereover. Y Q V The main object ofthe invention is to providea durable,simple, practical, economical and efficient rail anchor, or anti-creeper, possessing a maximum of strength, whichwhen properly. and fixedly applied to the base portion ofa track rail will effectually resist and prevent the creeping tendency of the said rail. p I Another object of the invention is to provide an improved rail anchor formed from a single piece of high grade spring steel, hot or cold, but preferably heat treated steel, which under any and all conditionswill serveto prevent any tendency of the creeping action of the track rail toward an adjacent crosstie.

A. further object of the invention isto so construct my novel rail anchor that any-tendency of thetrack rail to creep. longitudinally will serve to force the body portion thereof outwardly, thus simultaneously forcing the .rail clamping members inwardly, thereby causing the gripping parts of the anchor to intensify its clamping action in contact with a the rail base to which thesaid anchor is secured.

The foregoingand such other objects as may appear from the ensuing description are accompllshed by the construction, arrangement.

' to location and combinationlof the several parts hereinafter more fully described, illustrated in the accompanyingdrawings and particularly pointed out in the'claims appended hereto, it being understood; that slight "changes .in the precise formation, proportions and In the-' accompanying drawings forming a partjof this specification it will be seen that: Figure l is a plan showing a portion of a bar or steel plate from which my improved anchor is formed. i

Figure 4 is aside elevation showing the anchor detachedandremoved from-the track rail. v V

Figure 5 isa plan of aslightly modified form of rail anchor, and a Y F ig.- 6 is an end elevationof theformjof anchor? shown in Fig. 5. I

Inthe embodiment of-my invention as illustrated, it will be seen that Fig. l'indi- .cates a portion of a bar or plate of spring sheet. steel from which the novel anchor is formed showing a line'3 designating the line.

of sep'aration of each anchor, a space 4 showi ing. the maximum amount of waste material,

that occurs in the. formation of each anchor,

and lines 5 and 5 to denotethe slits formed through the body. portion of the anchor for i the purpose hereinafter described.

Referring now to 2 it willbe seen that the anchor is shown applied to the base of a standard track rail. 6,,the said anchor being designated as an entirety by the letter B, and is formed from a-high grade of spring sheet steelpossessihg the requisite thickness and i dimensions to furnish amaximum degree of strength, pressing or stamping thesheet in suitably prepareddies, and at the upperpart thereof, at one end portion thereohi's formed anoverhanging, or overlapping clamping jaw member 7,;while at its opposite or other end portion is formed an. upwardly extending clamping or gripping member 8, said memhere 7 and 8'being adapted-to tightlygrip and clamp the base portionof the track rail and The bodyl portion 9 of the anchor is proeach side thereof, respectively; 1 r

clamping jaw member l and formed therethrough, each slit extending from a point intermediate the ends of the anchor to each outer end thereof, and during the stamping or pressing operation thatportion of the body portion below each of the said slits 10 and 10 isforced outwardly from "the central portion of the body at each of its outer ends forming the laterally ex tended members 11 and 11 adapted to engage with the cross-tie, when the anchor shallhave been properly secured to the base of the track rail 6. 1

It will be readily perceived that when the anchor has been properly and fixedly applied to the base portion of the track rail with the members 11 and 11 resting in engagement in the cross-tie 12, as shown in Fig. 3, the greater the tendency of the track rail to creep, caused by the strain of the heavy rolling stock thereover, the more intense is the pressure of the members l1 and 11 against the cross-tie thereby forcing the central portion l of' the body outwardly, thereby imparting a vertical shackle grip, caused by the tendency of the device to tip forward at the top when the rail advances initially, and simultaneously causing an inwardly movement of each clamping end of the anchor, thus intensifying the gripping power of each clamping member in contact with the track rail base.

In applyingthe 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 7 overlapping the upper inclined surface of said base,"withthe upper face of the clamping member 8 resting "of spring sheet steel formed with a rail clamping member at each end portlon there in contact with the lower face of thebase of the rail, then by driving the anchor endwise from the left hand end thereof, as shown in the drawings, with the-usual sledge or maul employed for li re purposes, until the inner face of the clamping member passes the other side of the rail base, when the said'clamping member 8 will immediately snap upwardly and tightly grip and clamp with the edge of the rail base, all of the parts in contact with said base being under intense gripping action with the base portion of the track raiL.

The anchor may be easily removed or detached from the base of the rail by striking the upper face of the clamping member 8 downwardly and then driving it off from the right hand end portion of the anchor, as will be readily understood.

It will be'readily evident that this particular formation of anchor may be readily-aplongevity.

. The slightly modified form of anchor,

such as is shown in Figs. 5 and 6 shows the outwardly disposed members 13 and 13 stamped out laterally from the lower .end

portion of the body of the anchor, eachof said members being formed with a curved extended outer face 14: and 14: adapted to contact with the cross-tie, said formation of each outer face serving to prevent all damage to the c foss-tie by the cutting in, scraping or otherwise defacing of the tie.

out is 1. A railway rail anchor formed from a single piece, comprising a rail clamping member at each end portion thereof, a body portion, and outwardly extended members stamped from the lower end portion of said body and extendingv from the central portion of the body to'each of its outer ends.

2. A rail anchor formed from a single piece of high grade spring steel formed with a rail grippingmember at each end portion thereof, a body portion. formed with slits therethrough said slits extending from each outer end to-a'point intermediate its length.

and laterally extended members formed 'from'the bottom portion of said body adapted to rest in contactwith a cross-tie.

3. A rail anchor composed of a single piece of, a body portion provided with slits therethrough, said slits extending from. 'apoint intermediate its length to each outer end, and outwardly extended members formed from the bottom portion of said body and extending from the central portion of the body to each of its outer encs.

4. A rail anchor formed from. a single piece ofmetal, comprising a rail clamping member at each end portion thereof, a body portion slit therethrough intermediate its height, said slits extending from the central portion of the body to each outer end, and outwardly extended iembers disposed longitudinally formed from the bottom portionof lit] the body and eirtending from its central portion to each outer end.

5. A rail anchor formed from a slngle piece,comprising.a rail clamping member at each ofits end portions, a bodyportion slit longitudinally intermediate its height, said slits extending from each end to a point intermediate its ends, and outwardly disposed longitudinal membersiormed from he bottom portion of the body, and adapted to contact with a cross-tie.
