HAROLD G. WARR, OF PARK RIDGE, ILLINGIS, f-ESIGN'OR TC THE P & M COMPANY, OF

CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

BAIL-ANCHOR.

a Application filed September 27, 1919.

To all cl2/1,0m t may concern Be it known that I, HAROLD G. WTARR, a citizen ot the United States, residing at Fark Ridge, in the county of Cook and State ot Illinois, have invented certain new and useful Improvements in Rail-Anchors, ot which the following is a specification.

My invention relates to devices for preventing the longitudinal creep of railroad rails and has for one of its objects to provide a novel and inexpensive rail anchor device which may be readily applied to the base iiange of rails of diiiierent contour, which will iirmly grip opposite edges ot the rail base with a biting hold during the presence of a creeping pressure on the rail and which will maintain its initial grip on the rail base by spring action.

'The device ot my invention preferably consists of a spring yoke member which engages the rail base and a tie-abutting member which has an interlocking engagement with the spring yoke, so that the grip of the device on the rail is increased during the creeping action of the rail. It has been customary, prior to my invention, to make the tie-abutting member of this general type of rail anchor in the form of a cast shoe which iits over one edge of the base iiange oi the rail. The spring yoke used in connection with this form of shoe is formed at one end with a jaw to engage one edge of the rail base and at the other end with an enlargement which iits over and engages the outer tace of the shoe. lith suoli a construction as this, a web forming part of the shoe, for example, that portion oi the shoe which irictionally engages the vertical edge of the raii base, intervenes between the said enlargement of the spring yoke and the edge of the rail base. In order to avoid a misfit of the anchor device on the rail base, this intervening `web must necessarily be of uniform thickness. It the intervening web be too thin, as often results from the shrinking or' the casting, the spring yoke member will he too loose on the rail base, and it the web is of greater thickness than is intended, the application of the spring yoke is very diiiicult. Further difliculty is experienced in properly applying these shoe members to oversized rails or standard rails having base flanges of different thickness, as it is not Specication of Letters Patent.

always practical to force the shoe onto the base flange, the distance necessary to eiect a proper iit. In such event, if it is possible to apply the spring yoke, the yoke will be too tight to assume its desired diagonal position across the rail base. Vith my invention, I overcome the above mentioned and other incidental objections to the general type ot anchor above described, by providing the shoe member of my device with a recess which permits the enlargement of the spring yoke member to direct-ly engage and take a biting hold on the vertical edge oi the rail instead of merely iitting over the shoe as is the case with the anchor of the type above described. Ey constructing the device so that the spring` yoke engages both edges orp the rail base, it is obviously unnecessary that the shoe meniber iit the rail base accurately, thus avoiding the loss due to imperfectly formed castings, which under present practice are discarded, and at the same time permitting a wider range of application of the device to rails of dii'i'erent standard contours.

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

The invention is illustrated in a preferred embodiment in the accompanying drawings, wherein- Figure i is a plan view oi a railroad rail showing an anchor device constructed in accordance with my invention applied to the rail base,

Like characters of reference designate corresponding parts throughout the several figures of the drawings.

Referring to the drawings, 10 designates a railroad rail and 11 one of the cross ties on which the rail is supported.

The device of my invention preferably consists of a spring yoke which embraces the base flange of the rail and a shoe member designated generally at 12, adapted to have'a'n interlocking engagement with one end of the spring yoke; and a. shoe member which preferably fits over one edge of the base flange of the rail and is formed with a lip which frictionally engages the upper inclined surface of the -rail base and with

lower lips

14, 15 which frictionally engage the lower surface of the rail base. These lips are connected by a vertical web designated by 16, the inner surface 17 of which preferably, though not necessarily frictionally engages the vertical edge 1S of the rail base when the shoe is applied to the rail in its operating position. The lower lip 14 of the shoe is formed with a downwardly eX- tending flange 19 which provides a tie-abutting foot adapted to bear against one of the vertical faces of the tie 11. A portion of the vertical web 16 extends below the

lower lips

14, 15, as indicated at 20, so as to rigidify the tie-abutting flange 19. The web 16 of the shoe is 'preferably cut away as indicated at 21 to provide a recess adapted to receive one end of the spring yoke to provide an interlocking connection hereinafter more specifically described. rfhe forward edge of the downwardly projecting portion 2O of the vertical web 16 isformed with a ledge or shelf 23 adapted to provide a suitable seat for the lower edge of the spring yoke member when the yoke member is in its operative position on the rail. The yoke member 22 of my device is preferably made of spring metal and is formed at one end with a jaw portion 24, the upper lip 25 of which is curved in a direction toward the tie 11 and is adapted to bear with spring pressure on the upper inclined surface of the rail base. The other end of the spring yoke 22 is formed with an enlargement 26 which engages the opposite edge of the rail base and when in operative position extends into the recess 21 as indicated in Figs. 1, 2 and 7. The portion of the yoke which eX- tends under the base flange of the rail is )referabl O'iven a slight set or twist as' y e s clearly indicated in Figs. 4 and 5. In Fig. 5 it will be noted that the enlargemen't`26 of the anchor stands at an angle with relation to the jaw portion 24, the angularity of the enlargement being in the direction opposite to the angularity of the upper lip 25 of the jaw end of the yoke. lVhen applying my improved rail anchor device to its operative position, the shoe'ineinber i2' is ntted over on'e edge of the rail basel in a position so that the flange 19 will bear against one of the vertical faces of a tie. The hook portion of the yoke is then fitted over the opposite edge' of the rail base and the enlargement 26 positioned substantially as shown in Fig. 6 of the drawings. The enlargement 26 is then sprung in a direction toward the tie and slightly raised so that the upper end of the enlargement will enter the recessed portion 21, and the lower edge 28 of the yoke rest upon the shelf 23 of the web 20.- This bending of the yoke from its normally twisted position as indicated in Fig. 6 to its operative position as shown in Fig. 7 is preferably accomplished by means of a claw bar or wrench 27. The inner face of the wrench 27 is preferably provided with a lug 29 which bears upon a boss 30 projecting outwardly from the web 20 of the shoe.

This boss providesa suitable fulcrum forv the wrench so that the maximum power may be applied to the spring yoke to apply it to the rail base. It will be seen that by subjecting the spring yoke member to a twisting strain during the application of the yoke to its operative position, the angular lip 25 of the jaw member 24 is forced downwardly so as to bear against the inclined surface of the rail base with spring pressure. The tendency which the spring yoke has to return to the normal position from which it was sprung causes the enlarged portion 2G of the yoke to bear with spring pressure against the wall of the recess 21, as shown in Figs. 1 and 7. This spring pressure is sufiicient to maintain the anchor on the rail in its normal position during any retrograde movement of the rail or other disturbing influences such, for example, as the vibration of the rail caused by the passing traffic. Vvfhen the device is in its operative position the spring yoke 22 preferably extends'diagonally across the rail base so that the edge 31 Vof the jaw 24 and the edge 32 of the enlargement 26 will take a biting hold on the rail 'during the presence of a creeping pressure.
