its grip thereon upon any tendency of the rail to creep.

Another obgect is to provide a rail anchor comprising separable parts which have an inlei'locking engagement under 4t-he rail adjacentone side of the rail base whereby .the king portions` are readily accessible interi. and win, eby the rail anchor may be more readily applied tothe rail base.

@respective detached parts of the anchor;v Fig.

inay be called the clip and the L further object is to provide a rict-ional gripping device having means for preventing the loosening or disengagiiig of its cooperating parts due to vibration and to a leseeiiing of'the pressure which tends to maintain said parts in close wedging en` gageinent.

An. `dilitio-nal object is to provide a twopart i anchor with a guiding pro]ection or tongue by which one part may be readily guided into wedging engagement with the other part. The accompanying drawings illustrate a simple and practical enibodimentof my invention.

ln the drawingst-l`igure l is an eleva-v tion of the rail anchor securedto a rail base in asseniblcd position. Fig. 2 is -a top plan View of C.. rail 'having the anchor secured thereto and showing the relation of the parts with respect to 1the adjacent cross-tie. Figs. 3 and 4 are perspective Views of the two 5 is a modification of a detail.

The form oi rail anchor illustrated cornprises two members, ,the large'rof which smaller' of -which may be called the mate. The clip is 'provided with a rail-base-enUa-ging jaw 1 and the mate is li rovided wit a somewhat similar jaw 2.

the rail 3 by virtue of the under-cut wall or'jaw 4 on the clip which cooperates with the corresponding under-cutvwall or rib 5 on the mate and by Virtue ofthe diagonal arrangement of theseengaging walls with respect to the 4length' of the rail when in assembled position (see Fig. 2). The undercut Walls exert pressure onl each other in substantially Aa horizontal direction, the pressure in each case' resolving itself into two forces, one normal-f to the slanting Sur- `faceand o'ne parallel thereto, the latter force impels one member upwardly and the other member downwardly thereby insuring a lirrn interlocking of said Iiieiiibers.A AS a result of the said diagonal movement a rela tive longitudinal movement of the clip and the mate in the proper' direction results in drawing the jaws l and 2 closer together.'

The clip member in the form illustrated inl Fig. 3,'is'provided with an extension or tongue 6 and 4with a downwardly ext-ending flange 7 adapted to abut against the side of an adjacent cross-tie 8 when the railanchor' is applied to a rail. substantially S shaped in cross-section and is providedv at one end preferably with a Thev mate is flange or wall9 against which-hammer blows may be directed when drivingthe matie into firmh wedging engagement wit-hf the clipl `The clip is constructed preferably of malleable iron orlother Suitable material whereby the extension 6 may be bent to a considerable angle from its normal pos'ttoa without dangen of breaking it- OH. The Inatc .may bealso constructed of malleableii'on of it may be made as a drop forging,l or it be made in other ways.

The-anchor is applied to a rai'ljby" slipping the jaw l of the clip member; 0V r one edge of the rail base and then driving 'the jaw firmly on to said rail base with plied to the opposite side of thdrailbase at some 'distance from the t-ie' and is slipped loosely along the rail' 4base toward the tie, e

the extension 6 coperatig with the downwardly extending under-cut' rib or jaw 5 and' thereby guiding the mate into wed 'ngengagement Awith the cli member. -he

mate isheadrven'towar 'the te'by striking againstaise extension 9,i whereupen both wedging engagement beneath the rail and whereby the opposite jaws l and 2 .firmly grip the rail base between them.'

With the wedginF surfaces 'of the two parts ot the rail anchor located near one side of the rail base, the application of the rail anchorto the rail is facilitated, as the clip vmember may be readily applied to the guiding tongue in a position where it is easily accessible. If the .design were such that the wedging engagement tool: place under the middle of the rail, it would be necessary to scrape out considerableballast from beneath the rail before applying the two'fint-erlocler ing members and itwould be more di'iticultto insure a satisfactory'engagement of the vvisprevented@ yIt is apparent thatv the clip c and the mate' maybe locked in any position ,whiehtheymay happen to assume of rela# 4tive;adjustment longitudinally with respect L to. the ,ra'ilfr when iii y "ssembled position. @Upon any tendency of the rail to creep it is Aapparent thetendency of the mate and clip il' be to cause an increased Wedging' ac- --tion and an' increased grip on the rail base.

When the'rail moves lto the rear slightly 'as sometimes happens, owing to a contraction thereof due to cold, or owing to other causes,

#the pressureofthe downwardly extending 4iange of the clip member against the tie is relaxed.` `The rail anchor as a whole may even be withdrawn from immediate contact with the tie.r Under these circumstances, however, the` clip and .the mate maintain their-'eifective grip on thejrailbase and move as a unit w' .the rail. Owinglto the posi tivedocking means which maintains the partsflinj the :nosteili'ectivegpositicn of longitudinal adjustment with respect to each other, theyea'fn' t-hiove'relatively'fin a direction to decraeit "e wedging action and relax their-grip. Consequently if the rail a ain movesA forward, until the anchor a uts against -the"te",fnrther forward movement is effectively prevented'. Said parts are not locked against further movement in a direct-ion to increase the wedging engagement,

however, exceptin so far as they may already be in their most effective wedging position relatively to each other. y

. In Fig".v 5y a modifiedform of locking device is illustrated in which the extension 10 of the wall or rib 4 has the general form of a jaw or hook. This extension aids in guiding the mate into wedging engagement with the Clip and as the mate is being driven incassa home,/into a irm interlocking enga-gement with the clip when the parts are being assembled said j aw 10 snaps over the rear end of 'said mate and effectively locks the saine against return movement.

It is apparent that the invention is not to be limited to the two Aforms of rail anchor described, nor to thedetails of said forms as all of the above were selected for the pur pose of illustration only. I1`uijtheiinore the features of the invention are applicable to other uses than the ones suggested licrein. I desire therefore'to cover broadly any suitable means which accomplish the desired results, and which fall within the scope of the appended claims.

What claim as my invention and desire to secure by.-Letters Patent of the United States is :H' i

l. VA rail .anchor comprising two members each rovi'dedwith a jaw adaptedto grip one side of arail base and each provided witha diagonally disposed wall adapted to coperatewith'the corresponding wall of the other member lto eitect a wedging engagement of said members beneath the rail base, the wall of one of said members being extended beyond the main body-portion of said member to guide said other member into normalcoperating position when said parts are being assembled on the rail.

2. A rail 'anchor comprising two jaw-carrying members having walls which normally engage beneaththe rail base to prevent separation of saidmembers along a line substantially transverse to the length of the rail,

-said Walls being arranged at a slight angle with respect to the length of said rail, whereby relative sliding motion of one member'with respect to the other will cause said jawsto grip the opposite sides of the rail base more firmly between them, one of said walls being extended to guide said members into proper wedging engagement with each other. A

3. A rail anchor comprising two members' having sliding engagement beneath the base of a rail along a. line slightly diagonal with respect to the length of said rail, one of said members having a projecting portion adaptved to guide the other member into proper wedging. engagement with said first member and adapted to prevent the return of said other member and consequentloos'ening of said wedging engagement.

4; A rail anchor comprising a clip meinber anda. mate having engaging walls diagonally disposed beneath a rail base vadjacent one side of said base, said clip member having. a `rearwardly extending projectionk adapted toguide the engaging wall of said mate into proper engagement with the cor-- responding wall of said clip member', said projection being further adapted to prevent l.

this 'withdrawal of said mate.

5. A rail anchor comprising aclip and a mate having interlocking wedging engagement beneath a. rail base, said clip having a jaw for engaging the rail baseand having a downwardly extending portion adapted to bear against the side of a tie, and having also a rearwardly extending locking projection adapted to coperate with said mate.

6. An anti-Creeper composed of` two pieces, each vhaving a jaw adapted to receive oneV side of a rail base, one piece having a channel extending somewhat diagonally with respect to'the longitudinal axis of the vrail and adapted to receive a portion of the other of said pieces, said other piece having an extension for e'ngaging within the channel of said first piece, and a flexible lug integral with one of said pieces, and adapted to be bent into engagement with the other of said pieces to lock the parts together.

7. A rail anchor comprising a clip member and a mate, having engaging walls diagonally disposed beneath a rail base, said clip member having a rearwardly extending projection adapted to prevent the with-y drawal of said mate after the parts have been assembled.

8. A rail anchor comprising a clip and a.

mate having wedging engagement beneath a rail base, said clip having a jaw for engag-v ing the rail base and having a downwardly extending portion adapted to bear against the side of a tie, and having also arear.- wardly extending locking projection adaptedto coperate with said mate.

9. An anti-Creeper composed of two pieces each having a jaw adapted to receive one sidel of a rail base, one piece having a channel, a wall of which extends somewhat di-v agonally. with respect to the longitudinal axis of the rail, said channel being adapted to receive an extension on the other of said pieces, said extension having also a diagonally arranged wall adapted to bear against said first diagonal wall, 'one of said pieces having a flexible lug integral therewith,

adapted-to be bent so as to obstruct the return movement of the other of said pieces.

10. A rail "anti-Creeper consisting of two members, each provided with a jaw adaptedv to receive one side of the rail base, said members. being relatively movable in a direction substantially parallel to thel rail, and having abutting faces arranged somewhat diagonally and adapted for sliding contact, whereby ay relative movement of said'members longitudinally will cause a transverse relative movement of said-jaws to grip the rail base firmly, one of said members having a rearwardly extending projection adapted to be bent transversely across' the rear of said othermember to maintain said members in finally adjusted position.

l1. An anti-Creeper for rails comprising a plurality of members relatively movable toward and awayv from a crossJt-ie to vary the Ieiifectiveness of the grip of the anticreeper on the rail base, two of said members engaging eacli other beneath and near one side of the rail base, one of the engaging parts carrying an extension arranged at the side near the engaging surfaces and adapted to be deflected nder the rail base to'cop'erate with the ot er engaging part and lock thesame.

12. An anti-Creeper for rails comprising two parts having sliding engagement beneath a rail base and adjacent to one edge thereof, and manually operated locking means therefor also beneath said rail base and adjacent t-o one edge thereof, whereby PHILIP lV. MOORE.
