RAIL ANCHOR.

Application filed November 13, 1924.

To all 107mm t may concern.:

Be it known that I, WILLIAM I-I. DE BUsK, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of (Illinois, have invented certain new and useful Improvements in Rail Anchors, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to rail anchors of the type adapted when applied ,to a rail in Contact with a crosstie or other fixed part Vof a roadbed-to hold the rail from movement longitudinally. It is the principal object Aof my invention to provide a construction of this type in which a aw member is held in gripping position by means of a clip adapted to be swung from a position at one side of the rail into engagement with the upper face of the flange of the rail7 the arrangement being such that in the swinging movement of the clip into operative position the clip passes an intermediate critical point beyond which the clip is permitted to loosen very slightly whereby the pressure of the jaw. member upon the clip tends to hold the clip in operative position.

It vis 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 my several objects are illustrated in the drawing and are hereinafter specifically described. That which I believe to be new and desireto cover by this application is set forth in theclaims.

In the drawing,

Fig. 1 is a face view of my improved construction in position upon a rail which is shown in vertical cross-section;

Fig. 2 is a top plan view of the parts shown in Fig. l;

`Fig. 3 is a view similar to Fig. l, but showing a slightly modified form of construction; and

Fig. l isa ,top plan view shown in Fig. 8. i

Referring to Figs. l and @of the drawing, 5') indicates a rail of any approved type supported in position upon a crosstie 6. A jaw member comprising a body 7 is mounted upon the flange of the rail at one side thereof, said jaw member being provided with an arm S. extending across beneath the rail from one edge Aof the body, Said arm S being l of the device Serial No. 749,656.

held tcnsioned and distorted slightly, as indicated by dotted lines in Fig. l, by means of a U-clip 9 the legs of which are provided with turned end portions l() which are adapted to engage the upper face of the flange of the rail at the side thereof opposite from that at which the body 7 engages.

In the application of the device to a rail, the member 7 is first slipped into position from the side of the rail; the clip 9 is then placed in position in engagement with a iagonally-disposed portion 11 of the arm 8, with the clip turned in clock-wise direction from the position shown in Fig. l at one side of the rail, being held from withdrawal from the arm by means of a downwardly-extending end portion l2. Upward pressure is then applied upon the arm S, until the turned portions l0 of the legs of the clip are caught over the edge of the flange, whereupon the clip is driven or otherwise forced to turn in countercloclwise direction in Fig. l about the point 9aL into operative engagement with the flange as `shown in said figure. In this turning movement of the clip, the arm 8 is' first moved upwardly until the point 9 of the clip passes the corner of the flange, and then during the latter portion of the movement of the clip the arm 8 is permitted to move downwardly very slightly in the direction away from the rail, the point 9b of the clip being determined by a perpendicular from the point 9EL to the leg l0. This downward movement of the arm permitted by the clip serves to decrease very slightly the tension of the arm, butit results in a virtual locking of the clip in operative position, 4in that in the final applied position of the clip thc f downward pressure upon the clip tends to move the clip toward the rail rather than away from the rail.

In Figs. 5i and 4, the jaw member is inthe form of a casting rather than in the form of astamping from a plate of sheet metal. the arm 13 of this -form of device being heavy enough as to resist bending lo auf.' appreciable extent. In this :torni the body lis provided with an abutment plate 'iii formed integrally therewith, and an upwardly-extending lug 16 is provided for engagement with the edge of the flange. An intermediate. position of the clip 9 is indicated by'dotted lines, Showing the arm 13 Lio , tions illustrated in my drawing, it will be understood that I .do not desire to limit myself to the precise details as shown except so far as the same are hereinafter specifically claimed, inasmuch as it isl evident that changes may well be made in the detailed form without departing from the spirit of the invention.

I claim l. In a rail anchor, the combination with i a member comprising jaws adapted to engage the flange of arail at one side thereof, and an arm extending across beneath the rail in spaced relation thereto, of a clip engaging the arm and adapted to swing from a position a't one' side of the rail into engagement with the upper face of the flange, the arrangement being such that as the clip approaches itsmopera'tive position t-he downward pressure of the arm on ythe clip tends to swing the clip into such operative holding position.

In a rail anchor, the combination with a member comprising jaws adapted to yengage the flange of a rail at one side thereof, and an arm extending across beneath the rail in spaced relation thereto, of aclip engaging the arm and 'adapted to swing about an axis extending longitudinally of the rail and adapted in diagonal position to engage the upper face ofthe flange, the arrangement of the clip being such with respect to the slope of thel upper face ofthe flange that when the clip is, in operative posit-ion the downward pressure of the arm on the clip tends to retain the clip in operative holding position.

3. Ina rail anchor, the combination with a member 'comprising yjaws adapted to en-l gage theflange'of a'rail'at one sidey thereof, an arm extending across beneath thel rail in spaced relation' thereto, anda hook on said arm, of a' clip "engaging said hook and adapted to 'swing thereabout from a position at'one side of the rlaiflfintoengagement with ,the upperface of the Harige; tlie'arrangei ment being v'such Ythat'a-s the clip approaches its(Operative`-ho'l'dng. position'the downward prsslfr'e "Qfthfe Brin' @11 the din" tends to swing 'thewclip into "auch operative holding 4 .('LHJ Y I 4- flri'a, rail anchor, thenelnbnaton with a member comprising jaws adapted to engage the flange of a rail at one side thereof, and an arm extending across beneath the rail in spaced relation thereto, said arm having a downwardly directed portion substantially beneath the edge of the flange, of a clip engaging the arm and held in such engagement by the downwardly directed portion, and adapted to swing from a position at one side of the rail into engagement with the upper face of the fiange, the arrangement being such that when the parts are in operative gripping position the arm must be lifted slightly with respect to the fiange for disengagement of the clip from the flange whereby the pressure of the arm on the clip serves to hold the clip in operative position.
