EDMUND B. POWERS, 0F NEW YORK, N. Y.,

ASSIGNOR TO EMPIRE RAILW'AY PELIY ANCE CORPORATION, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK.

Be it known that I, EnMUNn B. POWERS, a citizen of the United States, residing in the city 0l New York, borough ot' Brooklyn, in the county o'fKings and btate of New York, have invented a certain new and useful lm- .prove-ment 1n nticreeping Devices for lhtilway-Rails, ot which the following is a speciiieation.

The invention relates to that class ot auticreel'iers in which the rail is held by a` roller engaged between the hase-flange ot the rail and an angular t'aee ol a lng formed on the tie-plate upon which the rail is supported. and the object of the invention is to provide simple, inexpensive means t'or holding the roller against vertical movement and escape from the angular space in which it performs its l'innetion.

The invention consists in certain novel vtentures and` details of consti-notion hy which thefahove object is attained. to he hereinafter. described.

The 'aeeonnmnving drawings lorm a part ot' i this` specification. and show approved 4forms ot theiinvention.

Figure 'l is a 'plan view showing a portion a prcl'erred `form of' roller. Fig'. is a efnresponding vertical section. partly in elevation, the planevotsection being indicated by the line QY-Q in Fig. l. Fig. 3 is a plan view ot the same roller on a greatly enlarged scale, Fig. -lis a corresponding side' view. Fig. 5 is a vertical section taken on the line .if-5 in the succeeding figure. Fig. l' is a l'iorizontal section through adjacent portions ol the hase-flange and roller. taken on the plane indicated in Fig. 5. Figs. and 8 are side elevations on a smaller scale. showing modi tied ferais ot, the roller.

Similar letters ol" reference parts in all the figures.

is the read ot' a rail and .V the hase flanges supported on the tie-plate li secured to the tie, not shown, hy spikes l) driven through holes o in the plate, with the spikeheads engaged with the hase-flanges as usual. On the upper lace ol the tie-plate at the outer end is a transverse rih or ahnt ment l engaged hy the hase-flange V and serving to hohl the rail against lateral mme ment.outwardly, and on the opposite end is a transverse lng W having its l'aee. adjacent to the hase-flange A2 formed angularly relaind' :ate like 'and then forcing' the FOR RAILWAY-RAI`LS.

tively to the edge of the flange as at tf', the ends ol the lug being nearer to the llange than the central portion and forming a. llat` tened Vshape as shown in Fig. 1.

A roller E having vertical' eiiirrngations or teeth 1"/ lies in the angular space thus provided and by its frictional engagement with the hase-flange on one side and the angular face of the lug on the other, par tiallv rotated by the creeping movement ol the rail upon the tie-plate until the roller is crowded into the gradually narrowing space to a point at which its flange and lug is sullicient to hold the. rail against further longitudinal movement. A single. angular face fr will serve to hold the rail against creeping in one direction lint the flattened V-shape is prelerahle tor Athe reason that the roller is held against escape due to a reverse movement of the rail and also will hold the rail against movement in either direction.

rlhe roller is preferably ot' such size as to Fit closely in the widest, portion o'lE the angular space and engage hoth the lug and the hase-flange. and thc roller is applied hy thus placing it while the hascvtlange is elevated rail dmvnward into close contact with the. tie-plate.

It is inniortant that the roller he. held against vertical movement which would per-- mit its cscaize upwardly. and for economical reasons it is necessary that .such holding means he simple and inexpensive.

ln the preferred lorm shown in Figs. l to l inclusive. the teeth or c( r|'ngal.ions; extend nearly to the lower end olt the rollerT leaving a narrow rim or helt F12 at the bottom, smoothly` finished helow the teeth lC. 'lhis helt is ot' such width as to lie helow the rounded angle A. formed at the junction ot' the side-f"ace A ol the hase--llange and the under iaee A" thereotl in all forms of stand ard rails. as shown in Fig. 5, and the roller is preferably ot harder steel than the flange and lugs so that as the teeth l".l of the roller are forced into the vert'ual tace .'t" of the flange` the smooth narrow helt l@ projects hcneath theI angle ol th'e [lange and hy its engagement prevents vertical movement ol: the roller. rl`he teeth and helt are also lorced into the face ol" the lng in like man-v ner hut in less degree. and this engagement ot' the heit ANTICREEPING DEVICE `jjjljtfm Specitcntion of Letters Patent.

- slightly thereunder.

'of' illustration`; an extremely slight taper will suffice andv will serve successfully. with `a vertical facefl2 by reason of the greater depth to which the teeth El 'will sink at the base of the'roller.V l

roller -of 'true cylindrical form as shown i'nIF ig. 7,'having a. narrow belt EA1 at its lower end' will also serve successfully by reason of the-engagement of such belt l beneath vthe'base-Hange of the rail before Id'ecribed7 or the conical roller E5 with the corrugations extending the entire length, as

I formtwith the face of the lug and rounded ,shown'in Fig. 8, may be employed, depend-1 ing4 upon the engagement of vthe tapered angle of the base-flange to resist vertical i movement.

l. in a device of the character set forth, a tie-plate adaptei,' l to support a rail, a lug on said plate having an angular' face adja-v cent to such rail, a langeless roller in the angular space between Isaid angular face and rail andengaging the base-flange of therail, a, corrugations on saidroller 'extending longitudinally thereof froni'thei-top vnearly to the bottom, the remaining' smooth portion at the bottom of said roller' .constructed to engage beneath the base-liange of the rail and .hold Said rollervagainst vertical movement. Q. in device'of the 'charactereet forth, a 'tieplate adapted to support a rail, a lug onea'id plate having an angular face .adjacent to such rail, a roller in the vangular space between said angularv face and rail and engaging the base-flange of the rail,
