Our invention relates to improvements in V rail anchors, particularly'to a type of anchor adapted to be sprung over the base portion i of arailroad rail in a position tobear against the verticaLface of a cross tie. V

One of the objects of theinvention is to provide an anchor device ofthe-abovecharrail, butwhich whenapplied in its operative position, willexert a strong grip on the rail and also present a tie abutment of relatively large bearing area adapted to bear against a vertical face of an adjacent cross tie. In this connection, the invention contemplates as one of'its specific objectsthe provision of a tie abuttingportion of suitable bearing area without changing the; cross-sectional shape of the bar from which the anchor isjmaderi and without extending the-tie abutting portion to-an objectionable distance below the bottom surface of the rail, thereby providing, I an abutmenthaving suflicient area to avoid; injuringthecross tiev and at. the same time.

provide sufiijcient rigidity to avoid. objec tionable distortion-of the tie abutting portion when-it is pressed against the cross tie.

Another objectis to provide, in a rail .an-

chor device adapted to be applied to a rail by engaging-one end of the anchor over one flange ofthe rail base and then pulling the other end upwardly across the edge of the other base-flange, a one-piece construction in V which the distortion of the under rail portion of the device, during its application to rail, will not interfere withrthe production of a firm grip'on the bottom. surface of the rail r base adjacent opposite edges thereof. A further objectis to provide an improved anchor device and method of applying the same, which does not require the use ofa special applying implement. In this con nection the invention includes a rail anchor construction in which one anchor maybe readily used in combination with any available bar for exerting the upward pulling force above mentioned-the loop end of one to anchor serving as alink connection between 7 the end-of the bar and the 'trating the useyofan anchor as a an h b ng n plied. v i o In the drawing I Fig. 1 is aside view of a rail anchor: c011 structedin accordance with our invention applied tothe base portion-of arailroad rail,

'g. 2 is a side view similar to l but showing the anchor inapositionwhich it assumes before the loopencl thereof is flexed over thebas'e flange of the rail and before the downwardly bowed under-rail portion is flexed upwardly by the forces exerted during the application of the anchor. to the rail, and

Fig. 3 is a view of the'anchor device corresponding to the position of the anchor in Fig. 1,-Fig. 3 being takenfrom the-side of. the rail looking toward the loop end of the anchor. Y V f Y .-The embodiment of our invention shown in theaccompanying drawing comprises a body portionflO which is normally bowed downwardly when free'of therail-to cornpensate for the upward arching ofsaid portion during the applying movement and thereby provide a bearlng against the bottom surface of the base atopposite edges thereof. Preferably the bowed contour is such that, when the anchor is fully applied,

the under-rail portion bears against the bottom of the rail 11, adjacent the opposite edges of the base :but remains out'of contact withthe center portion of said base surface. One end of the body' is turned in wardly toward the webof the railto provide a jaw 12 for engagement over one flange of the rail base 13 and to providealsoa'n upstanding portion 14: which norinally bears against the vertical edge of the rail base. The other end of the bodyjis' formed with an upstanding resilient loop l 5,a portion oi which normally projects'over the upper surface of the otherfiange of therail base. The end-portion '16 of 'thelo'op extends downwardly-to provide a portion" for bearing against 'the jvertical 'face of the cross tie 1'} r jects under the rail and thereby extends its" I tie engaging face inwardly toward the center-of the rail.

In applying the anchor to a rail, the jaw 12 is first hooked over one flange of the rail base in the position shown in Fig; 2. In this position of the anchor the curved portion 19 of the loop bears against the lower corner of the base flange 20 of the rail. By forcing the loop end upwardly across the edge of said base flange, the loop portion is flexed until it clears the upper corner of said base flange. I The stresses incident to applying the anchor'tend to the portion 10 upwardly toward the bottom surfaceof the base, but, due to the-bowed contour of the bar, it normally remainsout of contact with the central portion of the rail base, thereby, insuring in all installations a firm contact with the bottom of the base adja-.

cent the opposite edges thereof. The reflex action of the loop exerts a strong spring grip transversely of-the rail and also exerts a vertical gripfor holding the body portion of the anchor up against the bottom surface of the rail base.

In the drawing, we have illustrated a method ofv applying the rail anchor which permits the use of any available bar. In

the drawing, a bar 21' is shown bearing upon the head 22 0f the rail and connected, by

use of an anchor device 23 as a link, to the loop 15 of the anchor being applied, whereby great force can be exerted to pull the loop end of the anchor upwardly across'the edge of the base flange 20 ofthe rail. 'The large loop 15' of the anchor provides a suitable opening to receive the end of the bar 21 and the hook portion 18 may be readily engaged with the loop portion 15 of the anchor being applied to the rail.

While we have illustrated herein a rail anchor of certain specific construction, including the use of round metal stock, it will be understood that we do not wish to be-limited to the specific'features except insofar as the claims are expressly limited.

We claim 1. A rail anchor comprising a bar formed at one end with means for engagement with 7 one flange of a rail base and at the other end cationof the latter to a rail.

a resilient loop, a portion of which loop extends downwardly across the body and is adapted to be flexed, on upward movement of the said loop end, into spring gripping engagement with said rail base, the said downwardly extending portion of said loop being formed at its lower end with a hook portion providing a tie abutmentlwhich projects 1111- cler the base'flange of the rail and theextremityof said hook'portion being spaced from the under rail portionof theanchor to per mit engagement with the resilient loop of another anchor to facilitate application of the latterto a rail.

' A .rail anchor a bar hooked atone end to provide a jaw for engagement with one flange ofa: rail: base and looped'upwardly and downwardly across the bar at the other end to provide a portion overlying the upper surface ofthe. rail base and adapted t'o'be flexed over said rail base on upward movement of the loop, and a hook. portion at the extremity of thedownturned portion ofthe loop for bearing. against a cross tie and for engagement with theloop portion of another-anchor to facilitate appli- 4. A rail anchor formed atone end. with means for engagement with one flange of a rail base, an. upstanding loop at the other end foi -resilientlyengaging the other base flange of. the rail, a hook portion disposed at the extremity of said loop forengagement with theloop end of an anchor'being, applied in the manner specified.

. 51A rail anchor comprising an under-rail portion formed at one end with means for engagement with one flange of a rail base and at the other end with a resilient loop adapted to flex outwardly relativeto the rail,

on upward movement of the anchor, into spring gripping engagement with the other flange of the rail base; said under-rail por tion being normally bowed downwardly, when free of the rail, to compensate-for the upward distortion of said under-rail portion during the outward flexing movement of said loop, whereby a firm bottom bearing is iniured adjacent the opposite edges of the rail ase.

6. A rail anchor comprising an under-rail portion formed at one end with means for engagement with one flange of a rail base and at the other end with resilient loop adapted to flex, on upward movement-of the anchor, into spring gripping engagement with the for resiliently.- gripping; opposite edges of a rail base and comprising other flange of the rail base; said under-rail portion being normally bowed downwardly, when free of the rail, to compensate for the upward flexing thereof during the application of the device to a rail, the bow of the under-rail portion being so proportioned with relation to the normal distortion of the loop that the said upward flexing of the underrail portion will not extend above the horizontal thereby insuring a firm contact with the bottom surface of the rail base adjacent the opposite lower corners thereof.
