PATE T-onion GEORGE Loor Moons AND JAMEsRoBERr STEELE, or owneo; NEW'YORK I RAIL ANonoR Application filed November Our invention relates to an anchor or anticreeper device for railroadrails.

The object of our invention is to provide a one-piece self-locking anchor which will grip the rail with great tenacityand prevent the creeping of same In its broader aspects, our invention comprisesananchor formed from asingle piece of metal, havingthe proper amount of resiliency, which is bent at each end thereof and adapted to bear with considerable pressure against the fillet at the junction of the 7 web and flange-at one sidecof the rail and Q againstthe edge of the flange at the other side 1 of the rail, when thelanchor is applied to a railf The novel features of our invention will v be more fully understood from the following 7 description and claims taken with the accompanying drawings, in which: 7 V

comprises an under rail portion lg having an, inwardly bent flange overhanging portion 14, and an end upwardly directed toe portion -wardly sloping sectionl? which continuesin l a loop upwardly to the flangeoverhanging 15.- The under rail portion 13Ihas a substantiallystraight section 16 which extends from :the toe portion v to a point substantially .1 V v V H i 'Inthe latterpositionthe anchor grips the l railiand ,5 upon ajls'econd sharp blow of the hammer, at the point 22, the toe. portionsna ps further ontheirgiil and-the face 21' engages midway of its length; the remaining portion of said under rail portionconstitutes a'dow'nportion ig. 4 is a cross section of the anchor taken 5, 1927. serializ .,zsnz'zaiv as atlS, witha radius which is substantially equal to or preferably smallerthan the radius of the fillet 19 formed at the jun'ctionofthe flange and the Web of the rail. i

The'inner vertical facejof the-toe portion '15 is of steppedformation to providea plus.

ma or offset faces, preferably two in nu ber, designated by the numerals 20 and 21, V l V respectively, and which are preferablyfsiib-c stantially parallel to each other.

tion the straight section 16 is somewhat The free end of the portion 14 is curved,

In the preferred embodiment of our inven wider thanvthe width of the remainderjof the f'anchor for the purpose hereinafter set fortha,

Our device is applied toa rail by placing it transversely on therail to a position adjacent the sideof'the tie, so that curved end 18 abuts the surface of the filletli). The

anchor is preferably so proportioned that;

when it is hung on fillet 19, in'its initial positioin as shown "in Fig/"1, the preponderancy of its weight is at the right hand of the webof; the rail, and the'shortest" dis= tance between the curved surface 1 8 andi the face 20 of the toe portion 15 is less than be it'ween the shortest distance between the surface of the fillet l9 and the edge of "flange of the railat the-opposite, side, and further, the

shortestdistanc'e between the Qciir'ved "stir-Hf 'face '18 and the face2'l is less'than the first mentioned distance. 7 It will thusqbe seen, a

that, when thejanchor isfinits initial position it hangs loosely onthe fillet 19 and the upper end of the toe portion 15 engages the. base of rai1,withoutf any appreciable pres a rail supported on atie plate 11 carried on atie 12. An'anchor, madein accordance sure, at a point somewhat short of the contiguous edgeof the rail base. l/vhenthe. an-

the e igrate.Meet: t i e a. sh

the edge in Fig. 3, and the anchor, thus distorted, securely and effectively grips the rail by virtue of it tending to assume the condition from which it was sprung.

It will be noted that in the position shown in Fi 3 the shortest distance between the curved surface 18 and the face 21 of the toe portion 15 is greater than in the normal condition of the anchor before being applied to the: rail, so that, as the anchor tends to assume its normal condition, its resilient action presses the curved surface 18 against the fillet 19 and the face 21 of the toe portion 15 firmly against the contiguous edge of the rail flange. I In the latter position of the anchor, the upper surface 0 the straight section 16 is in close contiguity with the base of the rail, but does not normally engage the latter with any appreciable pressure. However, when the all begins to creep, under service contlitions, the under rail portion 13 firmly en- 8 an the anchor tends to tilt about a orizons the side face of the stationar he 12,

talaxis; This tilting action greatly increases the gripping action of the anchor on the rail, 23 of the straight section pressing firmly and u wardly against the base of the rail resisted by a downward pressure of the :o'turved'surface 18 against the fillet 19 with 'a resultant increased pressure of the face 21 of the toe portion against the contiguous oessive tilting. of the anchor, so it is ed of the base flange ofthe rail.

y widening the straight section 16 as heretofore mentioned the aforementioned tilting causes a stron pressure to be exerted against the base of t e rail without an exassured that, when the creeping action of the rail discontinues and the rail tends to reced'e, the :anchor is ableto easily assume its upright position. a

It willbe noted, that when our device is 'a lied to a rail, the free end of the portion 1 bears solely on the fillet l9, and as the anchor rotates about this bearing, during its transverse angular movement from its initial gripping position to its final gripping on the rai with said fillet and maintains astron transveise com'ponent dpressure agalnst t e rail.

When it is so shed the anchor maybe conveniently removed from the rail by merely striking the top of the toe portion 15 as" a sharp blow with a hammer.

It will be seen from the foregoindescription that we have devised a. slim) e anchor device which is easily applied to a rail and does not require to be held by the operator construction is such that the overha during such application. Furthermore, our mg portion of the anchor engages solely the lhet at the junction of the flange and the web of the rail, with the result that there .is

scarcely any localized distortion occasioned,

said end remains in close contact when the anchor is given a transverse angular movement to effect the gripping of the rail, and the stresses thus induced are distributed throughout the length of the anchor, so that a permanent set in the material of the anchor will not occur and it may be removed and replaced many times without losing its elficacy.

While we have shown our invention in but one form, it will be obvious to those skilled in the art that it is not so limited, but is susceptible of various other changes and modifications without departing from the spirit thereof, and We desire, therefore, that only such limitations shall be placed thereupon as 'are imposed by the rior art or as are specifically set forth in t e appended claims.

33. An anchor comprising an under rail portion adapted to engage the base of the rail, an overhanging portion connected to said under rail portion adapted to extend over the base flange of the rail and engage one side of the trail above its base flange when the anchor is placed in its initial position on the rail, and a toe portion projecting upwardly from said under rail portion positioned short of the edge of the base flange on the opposite side of the rail when the anchor is placed in said initial position, said anchor being deformable to bring said toe figrtion into engagement with the edge of said nge.
