srarn ANTICREEPER TIE-PLATE.

To all whom it may concern.-

Be it known that 1, DAVID P. lVoL- riaur'rnu, a citizen of the United States, re-

siding at lVashington, District of Columbia, have invented certain new and useful Improvements in Anticreeper Tie-Plates,

of which the following is a specification.

Devices for preventing the creeplng or longitudinal movement of rails due to heavy traffic conditions, have heretofore been universally constructed, so far as I am aware, with movable elements that grip the rail 11 )011 the attezn )ted lon itudinal movement l l b o g lhe sockets 6 and ra-ll clips seated therethereof.

'llhe primaiy object; of the present inven- I tion is to provide a structure, in which the rail-gripping means is fixed, and is properly engaged with the rail upon its application to said rail.

In the preferred form of construction, constitutes a part of, or is associated with; the usual tie plate, and the two cooperate;

to etl'ectively maintain a rail against longitudinal creeping or movement without thef necessity of any movable parts whatsoeven? While the invention may be embodied ini various ways as will be obvious from an in i spection of the claims hereto appended, for; the purposes of illustration two forms of.- construction are herewith disclosed that will practically carry out the. above'men-i tioned obj ects.

In the drawings: Figure 1 is a plan view of a tie plate, showing the anti-creeping; means in place thereon, and illustrating the "plate in its loose position. Fig. 2 is a view similar to Fig. 1, but showing a rail in place, 3,-is a cross sectional view on theline 2-2 of,

Referring hrst to the embodiment dis-f closed in Figs. 1, and 8, 'a-tie platefi is I employed, which is provided in its'upper faci; at two diagonally opposite, pointswith sockets 6, and at two-other diagdnal-ly opposite points with. penings 7 preferably having reinforcingvabutments ,8 bepind them,

butfixedly and rigidly located in the sockets 6 are rail-gripping or anti-creeping devices, each of which consists of a base 9 that registers in the socket, and is provided at its outer portion with an upstanding neck 10, the inner side of which presents a rounding cam or wedge face preferably provided with teeth 11. This neck carries a head 12 that partly overhangs the base 9, and the space between the head and base receives the base flange 13 of the rail R, so that each rail gripping element may be said to be in efiect a rail clip.

in are of a form, such as of an angular shape, that the clips or grips are rigidly interlocked Wlththe tie plate body so as to Also, it will be observed, by reference to I Fig. 3, that the base flange of the rail 1;) rests upon the bases 9, andthus securely maintains the gripping devices in the sockets. Having positioned the parts, as thus far described, the usual spikes 15 are passed through the openings 7 and driven into the' These spikes perform a plurality'pf tie. functions. In the first place, they, as usual, hold the tie plate and the rail in position, but they also effect a lateral turning or shifting movement of the tie plate, inasmuch as they act as wedges between the rail flange and. the reinforcing abutments 8.; and thus'cause the-cam faces of the-fixed grippingdevices to bite intothe margins of the 95' ase flange ,of the rail, securely locking the same against longitudinal -movement onthe tie plate. This action isr also provided for by having'the distance betweene'ach spike hole and the'opposite gripping element 'less "100 'tlian'the' width of thefrafl base but-large enough-to expose sufficient opening to start the point of the spike into the tie andbe edge of the holeor its reinforcement.

tween the rail "flange and the'out-er As a result of the above described application' of'the tie plate, it will be obvious that creeping of the rail in either direction' is positively prevented, .and at the sarhe time, there are no movable elements that are brought into action by-themovement of the rail. In other Words, the application,

of the device. effects the gripping action, and obviates the danger of inoperativeness from various causes that is incidental to movable parts of the above character.

With the particular form of invention just described and shown in Figs. 1 to 3 1nclusive,.it will be obvious that the tie plates may be constructed of cheap and inexpensive material, as usual, while the gripping devices can be of high carbon or hardened steel that will properly bite into the rails, and maintain an operative rail-grip ping action.

As an indication of how the structure may be modified, attention is called to Figs. 4, 5, and 6, wherein a tie plate 16 is disclosed that is provided with the usual integral longitudinal reinforcing ribs 17, the ribs in this instance, being preferably disposed out of parallel relation with the side edges of the plate. Each rib is provided at one end with a rail-gripping element, in the form of teeth with aspike-receiving opening 19.

18, and the plate is provided at the other end of each rib, and 'justinside the same, The manner of applying this embodiment of the invention is substantially the same as that already described. The rail is placed upon the plate 16 between'the reinforcing ribs, and spikes are then driven through the openings 19 into the tie. These spikes act as wedges to turn the plate laterally of the rail and cause the teeth 18 to bite the opposite edges of the base flange.

From the foregoing, it is thought that the construction, operation and many advantages of the herein described invention will be apparent to those skilled in the art, with out further description, and it will be understood that various changes in the size, shape, proportion and minor details of construction may be resorted'to without departing from the spirit or sacrificing any of the advantages ;of the invention.

Having thus" fully described my inven- 3. An anti-creeping device consisting of a single piece tie-plate having oppositely located rail gripping elements rigid therewith, andrail engaging means arranged to cause lateral bodily adjustment of the plate for forcing said elements into biting engagement with opposite portions of the rail.

4. An anti-creeping device consisting of a single piece tie-plate having rigid therewith diagonally opposite rail gripping elements, and fastening devices located op 0-.

site the gripping elements and arrange to cause lateral bodily adjustment of the plate, upon the fastening-down operation, to carry the opposite gripping elements into biting engagement with the rail.

5. A tie plate having sockets at two diagonally opposite points, and spike-receiving openings at two other diagonally opposite points, anti-creeping devices hav' mg bases that engage in the sockets and.

underlie the rail placed on the plate, said devices having teeth arranged to bite the base flange of the rail and having heads that engage over the said flanges.

In testimony whereof I hereunto afiix my signature in the presence of two witnesses.
