RAIL ANGIIOR.A v

TOaZZ whom t may omi/cern:

Be it known that I, FREDERICK A PRESTON,

a citizen'of the UnitedStates, residing at` Highland Park, inthe county.l of Lake and State yof Illinois, havefinvented certainy new anduseful Improveinents-inRail Ancho-rs,

of which the followingjisa specification.V

`My'invention relatesito rail anchors of the type adapted by Contact with a tie o-r other fixed part of thetrack to hold the rail from creeping or moving longitudinally.V vIt is the pricipal Object of myinven'tion to provide an improved form and arrangement of parts comprising a member applied to 'the flange of a rail from one side thereof, and a second ,member applied to the rail from the other side, one or both of such members having gripping engagement with the base flange of the rail, and said members having snap engagement witheach other, whereby they are heldinterlocked in their operative working positions with respect to the flange. Y f

It is another object of lmy invention rto improve devices of this type in Sundry details, hereinafter pointed out. The preferred meaus'by which I have accomplished my several objects are illustrated in the drawing and are hereinafter'specifically described.r `That whichv I believe to be new forth inithe claims. v

In the drawing, g Fig. `1 is a face view of the preferred form of `my improved rail anchor applied to a rail, which is shown in Section, the figure showing alsol by dotted lines the normal openingl of the awspof` the gripping' members. i

Fig. 2 is a face view ofone Of the members shown in Fig. 1, partly applied to a rail. i l

Fig. 3 is a fragmentaryview, showing one member of the anchorin final applied and desire to cover by Letters Patent is sety position, and with the other memberin its ber shown in Fig. 2.

Referring to the several figures of the drawing, in which corresponding parts .are

indicated by the same reference! characters,

10 and 11 indicate the ,opposite side portions of the base Harige of a rail, the head of which has been broken away for clearness of illustration. 1n Fig..1, therail is shown in position upon va cross tie 12 of'any approved type.

My improvedrail anchor comprises two members, oneof which is applied from the left in FigQl, and the other 'of which is applied from .the right. The first named member is shown comprising a cross plate or bar 13, provided with a depending platey I 141 whichserves as the abutment against the w tie 12. At its end portion, the bar 13 is provided `with a jaw 15 which is turned backwardly along the bar so as to grip the base fiange 10, the dotted line position in Fig. v1 showing the distortion to which the jaw is subjected in being driven into gripping position upon the flangel 10 from the left in Fig. 1. At its opposite end portion, the bar 13 isiprovided with an upwardly extending lug 16 which is preferably relatively low so as to avoid excessive distortion of the jaw 15 during itsapplication to a rail, but kwhich is ofy sufficient height tosnap into position opposite the edge of the base flange 11 when the member is-driven towardvthe right into its final operative position, as shown in Fig. 1. The member comprising the jaw 15, the tie abutment plate 14 and the, upward eX- teiision 16 is preferably made in the form of ra forging Yfrom a fairlylow grade steel, the arrangement beingsuch that. the member byitself ,when applied in its operative position,

as shown in Fig. 1, has a fairly strong grip upon'tlie rail and may be applied 'without danger of destroying the resiliency of the metal.-

`The other member of my improved anchor is in the form of a clip or yoke, comprising a. j aw or arm 17 adapted to engage ythe upper faceof the flange 11 and a jaw or arm 18 adapted to engage the bottom face of the bar 13. v f

As is clearly shown 'by' dotted lines in Fig.

` 1, the vopening between the jaws 17 and 18 is insufiicient normally for accommodating the thickness of'material between such jaws in their vapplied* position, as shown in Fig. 1. The result is that the clip comprising the arms 17 and 18 must be driven into position from the initial applied position, as shown in Fig. 3. Inasmuch as the clip 17-18 is to be formed as a forging fioin high grade steel, it Will be nndertsood that the resistance of the clip in'being driven into final operative position is very considerable, with the result that under ordinary normalconditions the arm 17 cuts into the flange 11, forming a transverse groove 19 therein. Villien the clip reaches its final operative position, as shown in Fig. 1, an upturnedYV lug or shoulder 2O formed on the end portion of the arm 1S snaps past a shoulder 21 formed on the bottom face of the bar 13 so as to have interlocking engagement therewith. The shoulder 21, like the shoulder 1G, is preferarbly of such height as to avoid lexcessive distortion of theclip 17 and thereby avoid any appreciable reduction in spring pressure ofthe clip when the lug 2O thereof snaps over the shoulder 21.

For holding the clip from slipping outv of engagementivitli the shoulder 21, ribs 22, 23 are provided extending longitudinally of the bar 13' at opposite endsV of the shoulder 21 for engagement ivitli opposite faces of Vthe arm 18, as will be readily understood.

By reason of the fact that the member comprising the arms 17 and 18 is formed of high carbon steel, such clip has a very strong grip upon the base flange, such grip being particularly effective for preventing longitudinal movement of the rail by reason of the fact that the arm 17 engages Within a groove 19, as above described. Also by reason of the stengtli of the clip, it Will be understood that the interlocking engagement betiveen the upivard extension 2,()l of the clip' and the shoulder 21 of the other member of the anchor is vvery strong, serving very effectively for holding the members in' their operative gripping engagement with the base flange of the rail.

By reason of having an interlocking ofV the tivo members, characterized by a. shoulder on one of thel members having snap enga-gement with a portion of the other member, the retention of the tivo members in operative position upon the flange is made muclifmore certain and much more reliable than is the case Jvlien reliance is placed upon the tight fit of the parts or upon the friction of the engagement, as is done in some instances inthe prior art. Furthermore, the shoulder 16, in addition to cooperating ivitli the jaw 15 to provide a firm grip on opposite edges of tlie rail base, serves as Van abutment to hold the bar 13 and jaw 15 from being displaced when the clip 17 is driven to its rail gripping position. So far as am aware, I am the first in the art to provide a construction of this type in which an actual interlocking of this type is 1novided, and I therefore desire to cover the feature broadly.

By providing a tivo part anchor, comprising one member formed of lovv grade metal and provided with the tie abutment, and a second member of high grade metal by which an effective gripping is obtained, the cost of the metal making up the anchor is very materially reduced, and the manufacture of the device is correspondingly facilitated. This feature is accordingly seen to be of very considerable importa-nce, and my claims to construed accordingly. Y'

lVhile I have shown the groove 19 as being cut in the top face of the flange by the clip during the application of the device to the rail I Wish to have it understood that 1 do not Wish to limit my invention to a depression in the form of a transverse groove, or to the production of suoli depression in any particular manner, except so far as the saine are specifically claimed; the important feature being that a part of the anchor engages a depression in thel rail at some point removed from'the edge of the flange. Y

iilhile I prefer to embody my invention in the form as illustrated in the drawing, it vviil be understood that 1 do not desire to be limited to the precise details of construction as there shown, except as the same is hereinafter specifically claimed, inasinuoli as it is evident that various changes might Well be made in the form of the device Without departing from the spirit of my invention.
