RAIL 'ancnon.

Application filed June 10, 1927, Seria1 No. 197,819. Renewed. May 5,1928.

My invention relates to rail anchors and has'for its primary object the provision of a rail anchor of improved construction whlch, when applied to the base flange of a rail, will exert a combination of several gripping actions thereon." A more specific object of the invention is to pro videa rail anchor device adapted to ,be dr ven -1nto frictional gripping engagement \Vlth one base'fiange.

of the rail and which is so constructed that parts of the device are stressed during the application of the anchor to a rail and thereby tend-to-urge' the rail gripping portions 1' thereof toward a position to effect a shackle rail. Y

- Anotherobject isto provide an anchor of i5 grip on the top and bottom surfaces of the theabove character made up of two parts,-

either'or both of which may be made from narrow strips of stock material, and so engagod with each' other that spring pressure of one member serves to hold the other n of the rail, and thereby provide, in effect, a one-piece anchor. -In this connection I contemplate, as one embodiment, the provision her so as to be pressed against the bottom surface of the rail base by the resilience 'of the rail gripping member.

ment and construction of parts which'will provide a convenient striking surface intermediate the rail gripping jaws, whereby the anchor, after the jaws-are driven into tight gripping engagement with the rail, maybe slightly distorted by further driving operationsso as to cause the transverse member of the device to snap over the opposite edge ot-the rail base. D

A further object is to'provide a device Y ofthe above character which is so formed loosened by the pressure of the jaw member against a cross tie,'and which may be applied to eitherside'of the rail in a p 'sition to resist either forward or'back ward reep ing movements of the rail.

The embodiment of my inventionshown in Figs. 1 to 4 inclusive, "consists preferably of a rail. gripping memberlO intended to exert the ma or grip of the device on the rail, and transverse member 11 which entends across beneath the rail base 12'a nd engages the opposite edge'thereof'so as to lock i I the gripping member 10 in its operative 'po-:'

sition on the rail. While the principal func tion of the bar 11 is to lock the gripping member on the rail, it' exerts 'throu h its mem er, .a; gripping action transversely o the rail and also a substantial frictional grip on the bottom surface of said rail base. I

blank ofuniform' width and preferably,

-a relatively small radius so as though not necessaril of spring metal and is formed near its en s with recesses 13 and 14. The said recesses are formed seas to fit tightl one edge of the'rail base. The blank is ent, Fig. 3, so as to provide spaced jaw portions 15 and 16 and an intermediate, upwardly projecting seat portion 17. The bends 18, 19, 20 and 21 are preferably'formed with to provide a construction. that will be relatively rigid transversely of the rail, but which, nevertheless, will permit some slight flexing both longitudinally and-transversely of theratl, when the member is. being applied to the rail.

The transverse. bar member is made preferably of steel and may, if desired, boot a higherorlower, grade of steel than that used in the manufacture of the gripping member. Thebarfits between the upstanding jaw portions 15 and 16 of the member- 10 and is held in position by the spring action of said jaw portion exerted against the opposite'edges of the bar.

mediate "portion IZ-of 'the member 10 and provides a .face 23 tioits 15 andltijand anchor to a rail. The vother end of the bar is formed with an upturned flange 24'adapted to snap over the opposite edge of the rail base when the gripping member is driven to its operative position on the rail-base.-

- Preferably the length of the transverse bar is such that the edge 25 of the-flan e 24 will stand a slight distance under tie lower edge 26 of the rail base when the jaws 15, 15" and 16, 1t?- have been driven to their operative positions, but which will be caused to snap over the edge of the rail as hereinafter described, by the further driving operat ions.

'lhe distant-e between the top surface 17 of the intermediate portion 17 and the bottom surface of the rail base is normally less than the thickness ofthe transverse bar ll. \Vith this arrangement of the bar,- the upward movement of the jaws 15 and 16 on the inclined top surface of the, rail base forces the upper surface 2mithe bar 11 into tight frictional engagement witlrthe bottom surface oftherail: base.

'jgl'lhe v gripping member and transverse bar are preferably assembled at thefactory and shipped asfa one-piece anchor. The anchor is applied to the" rail by hooking the jaws 15 and 16 over one flange of the rail base and then striking the end face 23. of the 'bar-pntil the jaws are driven into tight'frlction'al engagement with the top and bottoin to the configuration shown in- The down produce, turned end 22 of the. bar. fits over the interbar' 11 to permit theed'ge 25 of the flange 24 to snap over the edgeo'fthe rail-base. By whiclrstands outwardly 1 applying. the anchor in this manner, the from the outer vertical'edges of the jaw poris adapted to receive the hammer blows during the application of'the 25 of the bar snaps over the opposite edge of the rail base. The pressure exerted by the bar 11 against the bottom surface of the rail base, forces the; intermediate portion 17 of the gripping member 10 downwardly.

The downwardpressure on the intermediate ortion 17 effects a slight spreading of the ower end of the jaw portions 15 and 1,6 and thereby tilts the jaws from the dotted line position 'of Fig. 2' to the full line position.

This distortion'produces ashaekle grip of the 'rail gripping jaws on thetop and bottom, surfaces of the rail base in addition to the prior frictional grip effected by the transverse movement of the jaws. VVhen'the jaws are driven-to the limit of their movement, the'edge 25 of the flange 24, as before stated, remains a slightdistance; inwardly from the lower edge 26 of the rail base. Furtherdriving force applied to the end 2301 the bar 11 produces some compression of the metal of the inner face '28 of the flange 22 and also distorts the gripping member (presumablyby slight spreading or unrolling of theibends 18 and 21) so as to in effect, sufficient elongation of the compression of the metal and the slight distortion of theiinember 10, for exain'plebyd flexing theinte'rmediate posit-ion parallel to the e a position at a slight angle thereto, takes ortion 17 from a ges of the jaws to up all 'looseness of the parts and provides astrong grip transversely of the rail. This grip is maintained by the tendency which the anchor member 10 has to return to the position from which it was sprung by the final driving force.

In Fi s. 5 to 8 inclusive ILhave illustrated I flange 31 in' the slot 33 is preferably a driving fit so as to avoid-any looseness between the parts when the flange 34 of the bar snaps over the edge of the rail base. The gripping member des gnated generally by the refer: emote-character 351s vely sn'nilar to the gripbar 11;in the previously de- "The downturned end 31' of i ping member. shown in the previously described embodiment except that the bends 18f*-21',--instead ofz'being made normallv along lines perpendicular to the "longitudinal edges extending at anpoblique angle tothe said of the blank are bent' a'long a'line,

The a plication of this modified embodiment lie character of grip 'efl'ected arev subst'antially'the same as that describedwith the'cmbodiment described in Figsl to 4 in-' elusive and therefore need not'be again described.

In Figs. 9 to 12 inclusive are shown an other modified embodiment in which the princi'al-fcaturesfof the inventionare embodied in a. one-piece anchor device. The cross bar member 38 of this embodiment is made integral with the intermediate hearing portion '39 of the rail'- gripping jaw end portions 40 of theranchor. gripping end 40 consists of.;spaced upstandmg jaw portions 41-42, substantially the same as t ejaw portions of the two preceding embodiments. The bends 43,. 44, 45 and 46 are. made with a somewhat greater radius than the similar bends of the other The rail embodiments so'as to provide greater resib the gripping member with converging legs iency in a direction transversely of the rail and to also form-the intermediate portion of 47 .48 which add to the resiliency of the gnpping member vertically of the rail base. In, t is embodiment the topface' 49 of the intermediate member 39 bears directly against the' bottom surface of the rail base and is normally slightly -above the lower jaws 50'-51 when the anchor is free of the rail so that when the anchor is driven transversely of the rail base to force the lower.- 11

jaws 50-51 and the upper-jaws 52-53 into gripping engagement with the rail base,- the downward pressure on the surface 49' will tend to spread the lower portion of the jaw portions 4142' in a manner to effect a shackle grip of the rail grip ing jaws on the top'and bottom. surfaces 0 the railbase,"

. gas illustrated in Fig. 10'. The bends43 and 46 are formed along lines extending at an angle to the longitudinal edges of the blank so that when the rail gripping end is bent to its completed form, the intermediateporii ;ion 39 will stand at an angle to the vertically v disposed jaw ortions 41-42 so as to provide a suitable str ing sii'rface 54. This embodiment of the invention is applied to the base flange of therail in the same manner as the embodiments previously described by strikingthe edge 54. Thedriving force-delivered aga nst the intermediate portion of this em t and likewise the embodiment I in Fig 5 to 8 inclusive, tends to move its applied position the bar '38.

\Vhile I have illustrated my invention in the outer edge of the intermediate portion into alignment withthe outer edges of 4 vertically disposed jaw'portions and thereby exerts an increased vertical pressure against the bottom surface of'the rail base in addition to providing an effective elongation of three specificembodiments, it will be obvi ous that further modifications might be made without departure from the spirit of 4 .the invention. It will be understood therefore that I do not wish to limit myself to the specific construction herein shown and described except in so far specific limitations may appear'in the appended claims.
