'RAIL ANCHOR.

To all wlw/m it may concern.'

Be it'known that I, W'ILLIAM H. DE Busin, acitizen of theA United States, residin at Chicago, in the county of Cook and tate of illinois, have invented certain new and useful Improvements in Rail `Anchors, of whichthe following is a specification. My invention relates tof rail anchors, and it has for its object the provision of a new and 'improved form and arrangement of parts in a device of this type, by which a `double shackle hold can be had upon the i flange of a `rail for holding it from move`- ranged that there are no under-cut parts,`

ment longitudinally, the shackle hold upon the top and bottom faces of the fiange of the rail being eiiected preferably by parts located at the same end of the anchor as that at `which the anchor has its bearing `uponjthe cross tie. It is one of the objectsv of my inventionto provide a construction of this type inthe form of a` casting, so ar- Vthe' arrangement thus being suoli that the castingscan very readily be produced.

t'is another 'object of my invention to provide new and improved means for hold- .ing the anchor normally in its gripping po i sition, such means preferably comprising a small spring which shall function for holding the anchor inthe position in which the anchor is held by the pressure when there is a tendency for the rail to move longitudifnally with. respect to the cross tie.

It is another object of my invention to improve devices of this type in sundry details, hereinafter pointed out. The preferred means by which I have accomplished ymy objectsare illustrated in the accompany# ing drawings, and are hereinafter specilically described. That which I believe to be new anddesire to cover by this application is set forth in the claims.

ln the` drawings,`- Fig. 1 isa top plan view of my improved anchor. applied to a rail, partly broken away, the normal position of `the 'spring being indicated by dotted lines.

taken substantially on line of Fig. 1.

"Fig.4 is a. viewof the anchor as seen from the left inFig. 15, a portion of the cross tie being shown in" cross section. Fig. 5 is a top plan view of a modled form of construction, with the holding spring omitted. y

Fig. 7 is a top plan view of another modified form of construction, with the holding `spring also omitted in this view; and

Fig. 8 is a `longitudinal sectional view taken substantially on line 8-8 of Fig. 7.

Referring now particularly to Figs. 1 to 4, in which corresponding parts are indicated by vthe same reference characters, 10 indicates a Vrailroad rail supported by a crosstie 11. Across the bottom face of the rail extends the body12 of my improved anchor, `having a head 13 formed on one end thereof, and a head'14 formed `on the other end. Extending llongitudinally `of the body `12, from the Vinner face of the head 14 is a short arm 15 which is adapted to engage the upper face ofthe flange of the rail at Athatside ofthe rail. i

Fig. 3, the body 12 and the arm 15 are offset the rail, so that there is not any portion of As is best shown in the one which is undercut with respect to the other. As is'best shown in Fig; 3, the bottom face of the arm 15 and the top face of the body 12 are diagonally disposed so as to provide comparatively sharp bearings fol"` contact with the rail 10. Y

` At its Opposite end, formed with the head 13,'1Vhave provided a longitudinally eX- tending arm 16 provided at its end portion with a lug 1,7 adapted to engage the upper face of the iiange at that side of the rail. As is clearly shownin Fig, 1, the lug 17 for engaging the upper face of the flange at one side of the rail is considerably in advance of the sharp edgebearing of the arm 15 upon the upper face of the flange at the opposite side of the rail.`

As is also best shown in Fig. 1, each of the heads 13 and 14 is provided upon itsinner face with a comparatively sharp bearing for contact with the sideM face of the'flange at that side of the rail. Such bearings are indicated by thenumerals 18 and 19. These bearingsare also arranged in spaced relation with respect to the body 12 of theV anchor. These bearings are preferably 'provided byY giving the inner faces of the heads 13 'and 14 a double camber construction, as is clearly shownin said Fig. 1. r1`he head 14 is provided with a plate 20 which serves as the-bearing yfor* the anchor against the cross -tie 11.V

For applying the anchor of Fig. 1 tothe rail, ther device is brought into position belowl the rail with the body of the anchor swung in counter clockwise direction with respect to the position of the body in Fig.` 1. In such position, the arm is first hooked over the flange at one side of the rail, after which the head 13 is raised so as to permit kthelug 17ftopass the edge of the flange at the left in Fig. 1. Preferably the arrangement and construction are such `that it is necessary to apply a slight force forenabling the lug 17 to pass the edge of they flange V hen the lug 17 has been brought' into position level with the upper face of `the flange at that side of the rail, the anchor as awhole is swung in clockwise direction in Fig. 1 ,into substantially the position shown in Fig.' 1, the lug 17 being caused to travel Iupl the face of the flange toward the web of the rail as .this swinging motion of the anchor continues. The arrangement and proportions of the .anchor are designed to be l such fthat when the bearings 18 and 19, by contact with the side vfaces of the flange, stop `the swinging motion of the anchor, at the same time the bearingportions of the arm 15 andthe lug 17' willv have been brought into lContact with the upper faces of theflanges [at opposite sides of the rail. `With the an- `chor in lthis position, and with the bearing plate 20'in contact with the cross tie 11, any tendency ofthe rail to move longitudinallj.'v in the direction indicated by the arrow in saidFig. 1, will tend to swing the anchor in clockwise direotionin said gure, by reason ofthe fact that the anchor has a bearingy upon the cross tie at only one end of the an-A chor. At the same tim`e, there will be a tendency to twist the anchor in counter clockwisel direction, as shown in Fig. 3. -The bearings 18 `and 19 are yaccordingly brought into very Y tight gripping engagement with the side facesof thevflange of the rail, and the bearing portions ofthe body 12 and the` arm 15 are brought into very tight engagement with the top `and bottom faces ofthe flange at the right inr Fig. 1.

As willbereadily understood, the shackle hold upon the topA and ,bottom faces of the flangeoflthe rail is effected bythe arm 15 in connection with the body 12 of the anchor independently of any substantial gripping action of the lug 17.- The lug `17 may accordy Ainglybc made )ust strong enough to keep the head 1? fronidropping out of operative position with respect to the flange of-the rail, the anchor being designedV to permit sufh-A cient yielding of the arm 17 to insure that r#che twisting pressure of the anchor about a transverse axis `shall be resistedchiefly byY much as the `bearings of the body 12 and the arm 15 may be spaced at any desired dis'- tance from each other rlongitudinally of the rail, it will be understood that a very strong shackle hold or toggle grip can be effected by these parts upon the flange of the rail. 1n the same way, it will be understood that the bearings 18 and 19 can be spaced at any desired position longitudinally of the rail with respect to each other so as to provide the maximum shackle hold effect of such bearings upon the side faces of the` flange.

For holding the anchor normally in its operative position, l have provided a spring l21 which isheld in position within a groove in the upper face vof the body 12: This spring normally stands underneath the base of theI rail, as indicated by thedotted line positionsin 1 ande. .As will Abe readily understood, when the spring is forced toward theleft in` Fig.v 1 and is forced upwardly in. Fig. f1 so as to bring its free lend into engagement with the edge of the flange7 the 'spring will then exert a `pressure upon the anchor tendingrto hold the anchor in the position ton/'arid whichithe anchor is moved yby the pressure when the rail'tends to more in thegdirection indicated'by the arrow in Fig. 1. i

linv the modified forms of construction as villustrate/d in Figs. r5 to 8, Icorresponding parts of the anchorare Aindicated by the salme reference characters4 as are set forth above. Inv Figs. v5 and`7, the lspring 21y is omitted, the groove in they upper face of the body 12 being 'indicated by the numeral 22.

In Figs. 5 and 6, the body 12 normally stands 'inldiagonal position with yrespect to the directly transverse line across the rail. This effect is., of course, `attained by an appropriate positioning of the bearings 18 and 19 with respect to each other, such bearings being at such a distance from each other 'that they are brought into contact with Ythe side faces ofthe flange of lthe rail before the body of the anchor, in its swinging for application to the rail, as above described in connection wit-h the device of Fig. 1, isV permitted` to come into Athe directly transverse position. In order to effect this result to advantage, lthe arm for engagement with thel upper face ofthe flange adjacent to the point where the body of the anchor has its bearing upon the crosstie 11 is advanced with respect to the body 12 longitudinallv` ofthe rail so as to bring such arm into position overlying the cross tie 11. This arm in Figs. 5 and 6 is indicated by the reference character 23. As will be readily understood, the bearings 18 and 19operate inthe same manner as has beendescribed abovein connection with the device'of'Fig. 1. Likewise the bearings of the body 12 and the arm 23 are so related lto each other asto have a .shackleholdupon the flange :in ,theyv manner above described inconnection with the arm 15 of the device of Fig. 1. u

a In Figs. 7 and 8,`the construction is the same as that shown in Figs.` and', except that the arm providing the bearing upon the upper face of the flange adjacent'to the y pointwherethebody l2 bears against the y motion with respect thereto, with the bear-` cross tie ll ils-not caused to extend above the cross tie. In lieu thereof an arm 24 is provided, partially overlying thebody l2, the arm 24 andthe body l2 being provided with bearings intermediate their side faces, as is best shoivnain Fig.V 8, inlieu of having such bearings located directly at the faces of the parts as. shown in Figs. 3 and 6. This is, of course, done without affecting the operation of the device. Y

ySo far as I am aware,lv am the first in the art to provide a rigid anchor-,of this type in the form offa casting, adapted to be applied to a rail bya horizontal swinging ings ofthe device upon the rail so arranged with respect to each other that theizanchor is broughtfto its operating gripping position before the body ofthe anchor reaches the directly.transverse position.

So far as I am aware, l am the first in the art to providea `deviceof this type with aA springer other resilient meansso arranged as to; have a tendency to swing `the vanchor into its gripping position, the arrangement being such that the, action ofthe spring is fio auxiliary to the pressure for causing a tightening of the' anchor upon the railY when there is a tendency for the rail tocreep rather than icounter tothe, pressure. a l a u VVhileI prefer toemploy one of the constructions as illustrated inthe drawings and as above described, it willy be understood that I do not desire `to limit myself to the prec'ise constructionV as illustrated, except as the saine may be hereinafter specifically claimed, inasmuch Aas it is evident that vari ous changes might be made vin the construc-- tion withoutdeparting fromy the spirit of my invention.
