RAIL ANCHOR.

' Application filed April 20,

The present invention relates to rail-anchors or anti-creepers and is directed to the production of an improved one-piece type adapted to possess important advantages with respect to simplified application and increased efficiency as compared with the. structures as heretofore made.

A particular purpose of my present'improvements is to produce an advantageous form of rail anchor which will formatively allow of successfully meeting the severe conditions of advanced rail anchor design as to facility of application, rigid economy of manufacture and material and which in its installation will have a constantly maintained resilient grip upon the rail and will be progressively tightened by the forces which cause the creeping of the rail.

, The improved device of the present disclosure is generally of the-type of one-piece rail anchor, as shown in my prior Patents- No. 1,484,102 of February 19, 1924, comprising a bar or body portion having jaws at its opposite ends adapted to engage the flanges at the opposite sides of a rail and wherein a substantial degree of gripping effector pressure is obtained from a tightening action resulting from torsional displacement of the body of the anchormember. a

' An important feature of the present improvements consists'of animproved form of the body or connecting portion which may preferably be in the. form of a simple bend therein positioned at a point underlying the rail base flange and desirably to one side of the rail web. As a result thereof, a portion of the body member together with the jaw integral therewith is displaced angularly or longitudinally with relation to the rail and thereby to obtain a bearing contact between the anchor and the rail operative to maintain the related end of the anchor rigidly in vertical position and to relatively shorten the length of the body portion subjected to distortion. The angular displacementof a portion of the body portion, together with its associated jaw, isof particular value in the illustrated type of anchor, first, in its provision for obtaining an improved degree of vertical rigidity at one end of the anchor, while employing a jaw of relatively reduced size and. simplified form, and in consequence, effecting a saving ofmetal; further in providing for. obtaining a materially increased holding pressure on the rail by 1927.. Serial No. 185,084.

confining the torsional displacement Within a shorter length of the body portion of the anchor, and further contributing to the ef fectivenes's of the anchor in allowing for initially increased angular relation of the body portion with respect to the longitudinal axis of the rail from which it results in conjunction with the specific form of jaw employed, that the maximum holding pressures are obtainable before the body assumes a: position transversely of or perpendicular to the longitudinal axis of the rail.

My improved device is furtherv designed to incorporate further features of improvement, including an improvedform of jaw formed to allow of the important advantage of applyingthe device to a rail without requiring the use of a special tool therefor, the same being permitted by the simple operation driving the jaw into effective position upon the rail and to produce the required torsional displacement of the body by means ofa track maul or hammer.

The foregoing and other important features and advantages of the present invention will be more fully understood byreferenceto the accompanying drawings, wherein an approved embodiment of the features of my invention is illustrated, and wherein like reference characters are applied to the corresponding parts in the several views.

In the drawings,

Fig. .8 is a further desirable modification generally similar to the preceding, but wherein/the jaw is provided with a tapered or beveled entry surface to facilitate installation; i

I It) Fig. 9 is a perspective view illustrating the blank of the form of device shown in Fig. 8;

Fig. 10 is a plan view of a simple modification of the form first illustrated; and

Figs. 11 and 12 are respectively front elevation and plan views of a further modifi-' underlie the rail flange in general trans-- verse relation thereto, and is formed at its end portions with oppositely positioned inwardly extended jaws 4 and 6, arranged to overlie the rail base flange and to have gripping engagement with the inclined upper surfaces thereof. As will be readily understood, the device is applied to the rail by placing the body portion 1 to cross the bottom face of the rail with the aw loverlying the edge of the rail base the shoulder portion indicated at 5 engaging the edge of the rail flange.

The spaced relation of the jaw 6 to the shoulder 5 and associated jaw l, is such that thedistance to theinnermost end of the jaw 6 is less than the width of the rail base, and in consequence, in. applying the anchor to the rail the right-hand end, as shown, is initially tilted downwardly and the jaw 6 is lifted by a suitable tool and sprung forwardly to clear the edge of the rail and to finally assume its position, as indicated, bearing upon the upper surface of the rail flange. In the operation of lifting the jaw 6 on to the rail flange, the straight body portion of the bar will assume a relatively wide angular relation to the transverse axis of the rail, and further, will be given a resilient twist or torsional displacement, producing an initial resilient hold upon the rail flange. Thereafter, upon driving of the right-handend portion toward the tie, as shown at 2, the bearing surface of the jaw 6 will be forced to ride inwardly upon the upward surface incline of the rail flange, and in consequence, will increase the degree of torsional effect and resultant gripping action. In so far as described, the form and general application of the device to the rail corresponds in general to the disclosure of my prior patent hereinbeforereferred to.

In accordance with an important feature of thepresent invention the body portion of the anchor at one end, at the left as here shown, is bent into angular displacement with relation to the remaining or right-hand opposite end flange and with side of the rail base at 3, which in conjunction with the engagei'nent of the jaw 4, will operate to rigidly secure this end of the anchor in fixed vertical position and against tilting, and in consequence, effect the required securing of the one end of the anchor necessary to set up the torsional twist at the of the body portion upon the raising or lifting of the jaw 6 upon and under the action of the incline of the rail base flange. The securing of the one end portion of the bar against tilting from the vertical is accord'ngly accomplished by the simple bending operation without the provisionof additional metal to effect the result. In addition thereto, the angularlydisposed portion of the bo'dy'g provides for the desirable increase in the angularity of the major body portion conducive to obtaining a more effec tive tightening action, and, moreover, conlines the torsional displacement of the barto a reduced and limited section of the body, i, e., the straight body portion 1, as shown, whereby a; substantially increased torsion-a1 pressure is obtained under the action of-the jaw 6 riding inwardlyupon the inclined surface of the rail base flange.

As best shown in ,Fig. 2, in the stamping out of the blank, to provide the simple form of the jaw 4t with the shoulder 5 for engaging the edge of the rail flange, the body portion at 11 may be slightly cut away adjacent the rail flange edge to provide for clearance desirable in the application of the anchor to the rail. 1 The jaw 4 may also, and as shown, 7

be left in' parallel relation with the associated portion of the body during the bending operation whereby in its positionrof in. stallation it will. be angularly disposed to the rail, with the advantage that the edge of the shoulder portion 5 will bear against the rail edge to oppose the gripping action. The blank form of the jaw 6 is indicated by dotted lines in Fig. 2, and as shown, this aw is turned inwardly from the blank form to provide an upwardly extending and inwardly directed shoulder portion 12 positioned to engage the edge of the rail base flange and the jaw 6 may desirablyhave'its upward edge portion 13 rounded off in the manner as indicated. j

In the modified form of the device, as illustrated in Fig. 3, the construction conforms to the preceding, with the exception of the form of the jaw 6, which, as shown, is formed with its end portion tapered or rounded off at its under side at 14, thereby providing an inclined surface adapted to engage the edge of the rail flange and to ride upwardly thereon upon moving this end of the bar or anchor toward the transverse position, whereby this modified structure upon properly spacing the aw 6 with relation to the opposite jaw and with respect to the width of the rail, will allow of the device being applied by simply placing in position, and driving the jaw 6 end or the device toward the tie by means of a spike maul.

As will be appreciated, the features of my present invention may be embodied in varied form and arrangement without departing from the scope of the invention, and as illustrative thereof, I have shownin the remaining figures various modifications which may be made therein with advantages incident to the further improvements thereof, as shown.

In Fig. 1- there isshown a further modif fication of the design o'f the right-hand end of the anchor wherein the. return bend 15' of the bar for turning inwardly of the jaw 6 is formed to occur partially underlying of the rail flange and thereby determining the position of the shoulder 12"to engage the edge of the railflange at the inner edgethereot, and in advance of the position of corresponding engagement of Fig. 1.

In Fig. the right-hand aw is shown of the typejindieated in Fig. 1 of my prior patent "hercinbotore referred to, wherein the jaw is formed from an inwardly extended portion of the. blank turned into angular position. V

In Figs. G and 7 the-re is shown a further modified structure wherein-the left hand jaw 4 corresponds in form to the previous disclosures, but is, as shown, bent with relation to the angular portion of the body to be in substantially parallel relation to the face of thetie. The opposite jaw 6 is of a modified torn), bent :troin-the inwardly ex tending portion of the blank and formed to i provide a gripping and tightening jaw of the form to be lifted into engagement with the top surface of the "rail flange, and having a depending shoulder portion 17, as indicatet and arranged to efl'ect engagement with the edge of the rail base flange, the jaw end being formed with. a cut-away portion 18 below said shoulder, providing clearance and for the purpose of forming the jaw for bending with relation'to the body portion ofthe anchor.

In Figs. 8 and '9, there is shown a modified structure generally similar to the preceding but wherein the jaw 6 is formed with a rounded or inclined outer and lower edge 19, adapting this form of jaw for application to the rail flange without special tool, the installation being effectedby driving of the jaw 6' end of the device from extreme angular position toward transverse position. In the latter structure it will be understood that the spacing of the opposite jaws is such as to clear the rail base flange in the initial application of the device thereto.

In Figs. 10 and 11, the right-hand jaw end is of a modified form comprising a simple form of upwardly positioned hooked jaw 6 initially outwardly projecting from driving of the anchor toward the tie in themanner as hereinbet'ore described.

Fig. 12, here is shown an anchor in a modified form having the right-hand jaw formed with a return bend and witha shoulder 21 for engaging the rail base edge rising-from the body of the anchor at the rear of the hook portion, as 'indicated- I have accordingly produced an improved rail anchor of the type operating with a torsional resilient action wherein the one end of the anchor is firmly secured in its vertical position by a simple'angular displacement'ot a portion of the body, thereby eil'ecting a substantial economy of metal and further affording additional important advantages including the relatively increased resilient pressures obtained per unit of adjustment of the opposite end and the increase of ei'lective angularity permitted incident to the improved form. The angular displacement of the vertically secured end portion of the bar further produces the desired ottsetting of the related jaw member with relation to the major portion of the bar body thereby eliminating the requirement of a speclal bending operation to ettect this result. Also, and as will'be readily appreciated, while I'have herein described and shown the resilient distortion of the bar for obtaining spring action as occurring within the straight bodyportion of the bar, this distortion mayto a greater or less degree occur within that portion of the barend comprising the jaws without sacrifice of the important advantages of my improved design. It is accordingly intended in the claims that reference to the distortion of the barends shall'be broadly interpreted to comprehend eitherot' the conditions referred to.
