H. G. WARR RAIL ANCHOR Filed Jan. 5, 1928 2 Sheets-Sheet 2 Patented Apr. 21, 1936 UNITED STATES PATENT OFFICE 2,038,015 RAIL ANCHOR of Illinois Application January 3, 1928, Serial No. 244,216

21 Claims.

My invention relates to devices for gripping the base flange of a railroad rail in a position to abut against a cross-tie, so as to resist the tendency of the rail to move longitudinally under pressure exerted by passing traffic, such devices being known generally as rail anchors.

The principal object of the invention is to provide an improved anchor device of the above character which will grip tightly the base flange of a rail and which can be made of sheet metal with but little waste of material.

Another object is to provide an improved twopiece anchor device which is so formed as to provide a relatively rigid connection between the parts when they are attached together, and. which cannot be readily disconnected when the parts are once assembled.

Another object of the invention is to provide an arrangement of parts which, in addition to providing a strong frictional grip on the base flange of the rail, provides a tie abutting surface of large area which engages the cross tie at a substantial distance below the bottom surface of the rail base and Which at the same time effects an economy in the mount of metal used in the manufacture of the device.

Another object is to provide an arrangement and construction of parts whereby the end of the anchor adapted to exert the main gripping force on the rail may be made of such width as to provide a reliable frictional grip on the top and bottom surface of the rail base, and at the same time be sufficiently narrow to permit an increased gripping action on the top and bottom surface of the rail base when the lower portion of the tie abutting end of the anchor is forced against the adjacent cross tie.

Another object is to provide a rail anchor having one or more of the features heretofore noted and in which the rail gripping jaw member and the abutment for the opposite edge of the rail base are of such width and are so arranged with respect to each other that the anchor will readily assume a position diagonally across the rail in the event of slight longitudinal movement, and thereby exert a shackle grip transversely of the rail.

The invention has for further and more specific objects, such other new and improved constructions as will be hereinafter described and claimed for carrying out the above stated objects and such other objects as will appear from the detailed description of the invention.

The invention is illustrated in connection with two specific embodiments shown in the accompanying drawings, wherein Fig. 1 is a side view in elevation, with parts broken away for purposes of clearness, of one embodiment of my invention. 5

Fig. 2 is a cross-sectional view taken on line 2-2 of Fig. 1.

Figs. 3 and 4 are views in perspective of the cross-bar and jaw members, respectively, of the embodiment shown in Fig. 1. 10

Fig. 5 is a view similar to Fig. 1 showing an arrangement of parts which provides somewhat greater resiliency in the cross-bar member than is contemplated in Fig. 1.

Fig. 6 is a cross-sectional view taken on line 6-6 of Fig. 5, and

Figs. 7 and 8 are views in perspective of the spring cross-bar and the rail-gripping jaw member, respectively, of the embodiment shown in Figs. 5 and 6.

The embodiment of the invention illustrated in Figs. 1 to 4 inclusive, consists preferably of a jaw member I0, and a cross bar H, which have an interlocking engagement with each other, and which together embrace the base portion l2 of the rail. The member 10 is made preferably from a flat metal strip of uniform width, by bending the said strip intermediate its ends to the desired configuration. Preferably, it is bent to substantially U-shape so as to provide spaced jaw portions l3 and I 3 Each of the jaw portions is recessed to provide upper and lower jaws l4 and I5 adapted to be driven into frictional gripping engagement with the top and bottom surfaces, respectively, of the rail base. The said recesses are preferably disposed at an angle to the edge N5 of the member 10 so that the mem her, when applied to a rail, will stand at an angle to the bottom surface of the rail base. With this angular arrangement of the recesses, the lower portion of the member l0 projects under the rail base in a manner to provide a large bearing face for engagement with an adjacent cross tie I1 and also permits the use of a shorter cross bar H than would be required if the edges of the member I!) were disposed perpendicular to the bottom surface of the base. The bar H is disposed edgewise to the bottom surface of the rail and is preferably clamped between the jaw portions l3-l3 of the member ID by the resiliency of said jawportions.

In order to provide a rigid interlocking engagement of the members 10 and II, the member II is preferably recessed at one end to form a stud 18 adapted to extend into the hole I9 formed in the bottom portion of the U-member ID. The shoulder 20 of the recess 2| preferably engages with the forward edge of the member It. The bar I I is further locked in position by one or more projections 22, formed on the member ID, and adapted to engage the upper edge of the bar. The projections 22, herein illustrated, are in the form of spring tongues bent inwardly to project over the upper edge of the bar I I.

The other end of the bar II is cut away by a simple shearing operation to provide a bearing surface 23 and to form a locking shoulder 26, the latter of which snaps over the opposite edge of the rail base when the jaw member I0 is driven home.

The members In and II are preferably interlocked with each other at the factory and shipped as a single piece anchor device. The members are interlocked with each other by forcing the bar II downwardly between the jaw portions I3-I3 until the tongues 2222 snap over the upper edge of the bar. The said tongues will yield and the jaw portions I3, I3 themselves will yield slightly to permit the bar I I to be forced to its normal operating position.

In applying the anchor to a rail, the member I 0 is hooked over one edge of the rail base, in a position to bear against one of the vertical faces of the cross tie. The member is then driven transversely of the rail until the shoulder 24 snaps over the opposite edge of the rail base and the edge 23 of the bar bears firmly against the bottom surface thereof. While the connections between the members It and II are relatively rigid, there will be sufficient yielding of the parts to permit the shoulder 24 to snap over the edge of the rail base.

It will be seen by inspection of the drawings, in connection with the above description, that the blanks from which each of the members I9 and I I are formed, are of such shape as to involve but little waste in connection with the shearing operations. It will also be noted that the double construction of the jaw member I 0 provides a rail gripping member of such width as to maintain a firm frictional grip on the top and bottom surface of the rail base, but which nevertheless, will exert increased gripping force on the rail base when the lower portion of the member I0 is forced against the adjacent cross tie. The position of the shoulder 24 with respect to the spaced jaw members together with the relatively narrow width of said shoulder and jaw members permits the anchor to assume a position diagonally across the rail so as to effect a shackle grip transversely of the rail when the rail is subjected to creeping pressure.

The embodiments illustrated in Figs. 5 to 8 inclusive are somewhat similar to the embodi ments shown in Figs. 1 to .4 inclusive except that the jaw portion II) is somewhat wider than the jaw portion IU of the construction previously described and in that the bar I I is arranged so as to bear flatwise against the bottom surface of the rail base. One end of the bar II is formed with an upturned portion 25 which engages one edge of the rail base, and the other end is formed with an angular portion 26, which is inserted through the opening 21 in the member I0 and then pressed downwardly until the spring tongues 2828 snap over the upper surface of the bar so as to lock the surfaces 29 and 30 of the bar into engagement with the inner and outer surfaces of the bottom portion of member Hi In this embodiment, the angular portion 26 of the bar I I preferably extends to the outer edge 3! of the member Ill so that after the member Hi has been driven to its operative gripping engagement with the top and bottom surfaces of the rail base, the portion 26 of the bar II may be struck so as to cause the shoulder 25 to snap over the opposite edge of the rail base and to take up any looseness that may be present between the bar and the walls of the opening 21. With this embodiment of the invention, the member Iii grips the rail base in substantially the same manner as that described in connection with the embodiments shown in Figs. 1 to 4 inclusive. The member II a exerts spring pressure upwardly against the bottom surface of the rail base and also locks the member Iii in its operative gripping position.

While I have described my invention in connection with two specific embodiments, it will be obvious to persons experienced in this art that further modifications might be made without departure from the spirit of the invention. It will therefore be understood that I contemplate all such modifications as come within the scope of the appended claims.
