.Be litltnovvn that I, HIRAM H. SPoNnN- BURG, a' citizen of the United States, residing at Gurnee, in the county of Lake and State of Iliinois, have invented certain new and useful Improvements in Anticreepers, of which thefollowing is av specification.

.My invention relates to devices for preventing the longitudinal creep" of railway rails, such devices being sometimes called antilcreepcrs, rail` stays, or rail anchors; and

the invention has for its primary object to provide an anti-Creeper of novel and improved construction in which one or more of the rail gripping jaws is provided with a hard metal insert adapted to bite into the rail."

"A'further object of the invention is to proi'ride an arrangement in Whichthe hard metal insert is separately movable with `respect to the jaw, or other' rail gripping clement-With which it is associated, and is independently forced into contact with the rail; whereby the bite of the hard metal piece may be utilized to its fullest extent Withoutlessening the frictional grip of the other part or parts of the jaw.

A furtherobject of the invention is; to pro- Vide certain new and improved forms, consti-actions` and arrangements in devices of this character Which will be hereinafter' described and claimed.

The Iinvention vis illustrated in the preferred embodimentr rin the accompanying drawings, wherein l Figure l is a side view of the device in elcvation, the rail to which it is applied being shown in section; Fig. 2 is a plan view ot' the parts shown in Fig. 1, but in an initial and not the'ir operative position; Fig. 3 is a fragmentary,sectional plan taken on line 3-3'of Fig. 1; Fig. 4 is a View in perspective of the hard metal insert; Fig. 5 is a view in perspective of the malleable iron jaw, and Fig. ,6 is an end elevation of the device, the tie being shown in section viewed from the left'hand side of Figs. 1 and `2.

Like characters of reference indicate like parts-'in the several figures of the drawings.

Referring to the drawings, A designates a railroad rail ol ordinary form. the base of Which is designated B.

C is oneof the ties on which the rail is supported.

Athe rail base Patented oct. 3, 1911.l

It will be readily understood by those familiar with the various types of anti-'creepcrs which have heretofore been devised, that the improvements constituting my invention might be utilized in connection with a number of different structures. For the pur pose of illustration, and because the devices and arrangements'in question are considered of particular `value as improvements in this connection, Ihave chosen a structure in its general characteristics like the anti-Creeper disclosed in the, patent to Leighty No. 809,193, patented January 2, l1906. The devicel of this Shaped jaw by .means of a strap or bar having a hook at each end. In operation the wedge shaped jaw hears against a tie so that the creep of the rail causes a tightening action between the jaw-and the strap or bar which increases the lateral grip of the device on the rail base.

In thc device shown herein a tapered or wedge shaped jaw Dis provided, adapted to surround one edge oi" the rail base B, and this jaw is secured to the rail base by means ot a bar or strap I!) having at one end the hook or jaw F engaging with the rail base, and at thc other, the hook or jaw G which surrounds the tapcredjaw D. The jaw D is provided with a depending flange H constituting a tie abutment. vWhile the device is shown as constructed so as to simply bear against a tie, it is obvious that it might be permanently anchored or secured to the tie, or that instead of being abntted against or secured. to a tie, it might bc in like manner engaged Withany other stationary, or relatively stationary, portion of-thc road bed.

Jaw l) is formed at its rounded edge with a horizontal perforation or slot I adilpted to receive `thc preferablytapcred hard metal insertpieceJ formed on its edge engaging the rail hase with thc teeth j. Preferably the insert piece and the slot or perforation in the jawgn'e so conformed that the former may be secured in the latter before the anticrcepcr is assembled on thc.rail. This is to prevent the relatively small insert piece from being lost. For example. the perforation in the jaw is preferably so formed that two lugs or projections1 r', i" at the inner side of the ljaw. hold the .insert piece .I in position at this side. The back edge of the jaw is patent consists of a Wedge which is secured or clamped to .formed with lug K which, .when the' jaw is cast, projects` out from the back of the vjaw but can be hammered over into the opening, that is, to `thefull line positionf Fig. 3, after the insert piece has been put in place. The other end of the perforation I is pref- -erably undercut as indicated at 2.

i edge projectsa trifle beyond the curved'back surface of jaw D. By this arrangement,

when the strap E is driven onto the iaw D (both whenA the deviceisfrst appliedl'to the rail-and. afterward when the grip of the dei vice`is tightened by the tendency of the rail I to creep) its jaw or hookG is foreedyup' the .tapered jaw D, driving said jaw D into a closer frictional contact with the' rail base,

and at the same time said hook or` jaw G isV brought. to bear upon the hard metalainsert piece J which, as stated, is tapered a trifle and projects a trifie beyond the outer edgel of the jaw, and forces'said insert piece trans verselyagainst the edge of the rail base cansing its teeth y' to bite into and be embedded in the softer metal of the rail. llt will be understood that the jaw D, will be made of maileableiron or other relatively soft and tough metal (and the strap E may be made of the saine inletal) While the insert piece l .will be composed of hard steelor iron. ylhis loose ariangementof the hard metal eleu'ient in the jaw B, in the first place, makes it possible to produce an effective bite of the bard Ametal element which is not altogether dependent on an exaett. of the jaw on the rail base. If, for example, the jaw ismade a little too wide or too narrow, or in other respects does vnot exactly conform to the shape of the rail base, the capacity of the insert element for movement makes an effective grip a possibility. In theseeond place, with this arrangement it is possible to obtain an engagement upon the rail base o-f both the hard metal element and the malleable iron jaw in which it is mounted... their a hard metal insert. is yfixied in the Jaw it is obvious that the adjacent parts of the jaw are ltept out of effective .contact with the rail. `With the vinsert piece independently movable, and supposing it to be designed, as

shown, 'so that it projects from the back ofI the jaw D an amount equal to the capacit-y it has for eml'iedding itself in'the edge of the rail base. the driving of the strap onto jaw D will first force jaw D against the edge of the rail base and then force the insert to bite into the rail. The above .will be apparent from comparison of Figs. 2 and 3. The drawings show an adjustment of the parts which brings the inner surfaces of the jaw D and of hook F into Acontact with the edge faces'of the rail base. It would be possible, by tapering the openings in jaw D and hook F, to obtain a `greater wedging action between the jaw and hook and the rail base, in

`whiclrcase some little space Would'intervene between the edge faces of the rail basel and the opposite inner surfaces of the' jaw and'hook. -In this arrangement the movable I mounting of the insert piece J would have utility since, instead of being held out of contact with the edge of the rail, it could be made to move inwardly sufficiently to make an engagement.

Theoretically it might be possible to malte vSo exact a fit-between jaw D and the rail base that there -would be wedging contact between the top of the jaw and the top of the rail base, 'and straight clamping contact between the innersurface ofthe jaw and the edge face of the rail: that is, to have the edge of the rail meet the'inner surface of the jaw when a maximum Wedging action' has been reached; In practice, however, it is' ,not possible to make devices of this sort so that they will have any such accurate lit. If the grip is between the jaw andfthelat .sur-

faces of the rail 'base there will be some clearance atthe edge. If the edge is engagedA there will' be little or no frietional engagement between the dat surfaces.` lVith the jaw provided with a movable insert piece, as shown,t he'bite of the insert is in either case` made effective. and also the fric-` tional grip of the jaw onv the rail.

It will be observed that the jaw or hook Gr has considerable width rand that the u -s 'y per surface of the bar E is flat. Preferab y the jawl) is tapered longitudinally as well' as transversely. that is, is thinner on vertical lines at the end remote from the tie than at the other end. These constructions serve' to develop' considerable friction between the hook G 'and jaw D and between the ,strap and the lower surface of therail base, thus tending tokeep the parts in, theiroperajtive position. Preferably the parts of the de vice will be driven in place b v a Sledge hammer. The iaw D will be` first driven tight on the rail base and afterward `the strap member E driven as vfar as may be upthe l wedge constituted by the jaw. The end4 of the strap lprovided with tlie hook F stands away from the tie so that if'the rail has any I the anti-Creeper lhere siowjn, .it i's perhaps,

not essential in view ofthel fact that the design and arrangement of the parts issuch faste give by itselfla very close and effective grip of the deviceon the rail. As another preferred, though, not essentiallfeature of the device. as l/apprehend it,fa'portion of jawD is slit se as to forni a istrip Lwhich .130

devices which are therefore `do not limit myself to the par-- Y I d o not clai' can be bent up back of the jaw G when the parts have been driven into their operativo position. I n 1 From the foregoing it will be readily understood `that While the improvement invention is perhaps particularly valuable as `animproveinent upon the' sort of anti- Creeper shoWnL-itmight, nevertheless, be employed inconnection with anti-creeping structurally different. I
