RAIL ANCHOR.

Application filed Qctober 22, 1925. Serial No. 64,147.

My invention relates to rail anchors anding the has for its primary object the provision of a new and improved rail anchor device which, when applied to its operative aosition on a rail, will maintain its operative position thereon by spring pressure and which will lock itself on the rail so as to prevent accidental removal therefrom.

Another object of the invention is to provide an improved two-piece rail anchor. in which the parts when free of the rail, are normally held together by spring pressure, so that the parts of the device may be assembled at the factory and shipped therefrom, in readiness to be applied to a rail.

Another and more specific object of the invention is to provide a two-piece rail anchor in which one of the members is subjected to a torsional strain during its application to a rail, so as to exert a spring grip on the upper and lower surfaces of the rail base andis held in said torsioned condition by means of the other memb r, which is movable thereon and adapted to be driven into engagement with the rail base.

Another object of the invention is to provide an improved two-piece rail anchor, the parts of which may be made from flat metal blanks of such configuration as to avoid any substantial loss of metal in shearing the blanks. In this connection the invention contemplates a two-piece anchor comprising a rail base embracing member formed with a recess to receive the base portion of a rail, and a clip member of such shape that it may be formed from the metal removed from the recessed portion of the said rail base embracing member.

The invention has for further objects the novel arrangement, construction and combination of parts hereinafter described and claimed for carrying out the above stated objects and such other objects as will appear from the following specification.

In the drawings:

Fig. 1 is a plan view of a rail anchor constructed in accordance With my invention, applied to the base portion of a railroad rail.

Fig. 7 is a View of one of the blanks shown in Fig. 6, but drawn on a larger scale, and.

Fig. 8 is an end view of another embodiment of my invention.

Referring first to Figs. 1 to 7 inclusive of the drawings, 10 designates the base portion of a railroad rail and 11 one of the cross ties on which the rail is supported. The embodiment of my invention illustrated in the above figures consists preferably of a rail base embracing yoke member 12, made of spring metal, and a clip 13 adapted to support one end of the yokein its operative position on the rail base. The body portion of the yoke is provided with a recess 14L adapted to receive the base portion of the rail, the recess being of such configuration as to provide a aw jaw 15 normally bears with spring pressure agalnst the top surface of the rail base when the anchor is applied to its operative position, the spring pressure being effected preferably by subjecting the yoke to a torsional strain during its application {to the rail. The jaw 15 is preferably bent to an angular position with respect to the body and the body is preferably, though not necessarily, given a normal torsional set (shown best in Fig. 5) so that the end portion 16 will stand at an angle to the body of the yoke when the yoke is free of the rail. With this arrangement of the end portion 16 of the yoke with respect to the jaw 15, the end of the jaw will be forced downwardly against the top surface of the. rail base when the yoke is torsioned in the direction to bring the end portoin 16 to a substantially vertical position with respect to the bottom surface of the rail base.

The yoke is held in its applied torsional condition by means of the clip member 13 which engages the yoke and the base portion of the rail in such manner as to resist the tendency of the yoke to return to the 15 at one end of the yoke and an up-, standing portion 16 at the other end. The

the recessed portion 14; of the yoke so as to provide an interlocking engagement of the yoke and clip when both members are in their operative position on a rail.

The clip is preferably made of spring metaland is or" such shape and size that it can be "formed from the metal strip removed from the recess 1st of the yoke. The form oi? the blanks from which the yoke and the clip members are formed are shown in Fig. 6 of the drawings. By reference to Fig. 6, it 'ill be seen that the shearing of both blanks 12 13 produces but a very small amount of metal scrap, the pieces 01'? metal scrap being indicated in said figure by reference characters A, Band C. In producing the yoke blanks ior rails having base flanges or diiierent widths, the length D of the clip blank may vary somewhat with relation to the width of the yoke and in proportion to the increase or decrease in the width of the rail base. However, when it is desired to provide the clip blank with relatively heavy jaw portions 26 and 21, the length of the yoke jaw 15 may be varied to produce a longer or shorter blank, as may be desired. Under such conditions, it is also possible to obtain the desired result by cutting away the lower edge of the yoke shown at 22, in Fig. 2 of the drawings, instead of varying the length oi the yoke jaw.

The clip is preferably torined so that it will be necessary to spr ad the end. apart in applying it to the end 16 of the yoke. llith such construction the clip may be fitted on the and oi the yoke at the factor and shipped as a one-piece anchor, thereby avoiding any misiittingol' the anchor parts by the track workmen when applying the anchors.

In applying the anchor to the rail, the yoke and clip. assembled, as shown in Fig. are positioned on the rail base so that the j z T 15 ot the yoke will be hooked over one flange of the rail base, in which position, the other end of the yoke and the clip carried thereon will stand at an angle with respect to the bottom of the rail base, as shown in Fig. 3. A wrench o f the type shown in outline in Figs. 1 and 3, or of other suitable form, is applied over the clip and the yoke is torsioned Until the recesses 1'? and 18 of the (lib are in line with the adiacent edge of the rail base. The clip 13 is then driven longitudinally oi? the yoke 12, by striking the lower portion oi the wrench with a sledge or by otherwise applying force to the clip to more the jaw portii'ins 2t), 20 and 21, 21 into tight gripping engagement with the upper and lower surfaces of the rail base. The tongue 19 of the clip is so proportioned with respect to the depth ot the recesses 17 and 18 that it will snap back of the shoulder 23 of the yoke when the clip is driven home and thereby lock the yoke and clip on the rail. The torsional strain to which the yoke is subjected during its application exerts a powerful grip of the jaw 15 on the rail so as to maintain the yoke in its applied position. After the clip is driven to its interlocked position on the yoke, the clip end of the anchor may be driven longi tudinally of the rail to bring one face of the clip into engagement with an adjacent cross tie. The other end of the yoke may be driven toward the tie until the yoke stands in a position diagonally across the rail, as shown in Fig. 1 oi the drawings. in ii latter position the vertical shoulder 3 or the clip and shoulder El of the yoke take a shackle grip on opposite edges of the rail base to rcsiat the creeping movement of the rail. The tendency which the .spring yoke has to return to the position from which it was sprung tends to cant the clip so as to increase the grip of its jaws on the upper and lower tacos ofthe base flange of the rail. Ordinarily the fit of the clip .jaws on the rail flange will be tight enough to prevent any actual canting of the clip. However. it

there is any looseness pr sent it will be taken up by the canting action.
