i .isaevaf i Be it known that l, EDMUND Pownns, a

citizen of. thcUnited States, residing in the city of N ewYork borough of Brooklyn, in i the county of Kings and State of New York,

have invented a certain new and useful Improvement 1n rinticreeping Devices for Rail- Way-Rails, of which the following is a specification. Y

The invention relates to'anticreeping devices of that class in whichthe rail is held a to a tie-plate by the engagement of a rolling member in an angular space between the base-flange of the rail and an angular face on an adjacent lug secured to the tie-plate, and theobject of the invention is to provide simple, reliable and economical means for holding the rolling-member against upward movement and consequent escape vertically from such angular space. a

The invention consists in certain novel features and details of construction and arrangement by which the above objects are attained, to be hereinafter described and claimed. 1

The accompanying drawings form a part of this specification and show an approved form of the invention.

Figure l is a plan view showing a portion of a rail supported upon and engaged with a tie-plate. Fig. 2 is a corresponding vertical section, partly in elevation, the plane of section being indicated by the line 22 in Fig. 1. Fig. 3 is a top view of the rolling member alone, and on a larger scale. Fig. 4 is a corresponding side elevation.

Similar letters of reference indicate the same parts in all the figures.

A is the head of the rail and A A the base-flanges thereof, supported'on a tie-plate B secured to a tie, not shown, by spikes D or other suitable fastening means On the upper face of thetie-plate at one Specification of Letters Ritezit.

,ing a short distance beneath the flange'i i and shown as fhaving'a width equal to the length of the lug B In the angular space above described between' the lugand the rail is received a roll-.

ing member arranged with its axis vertical,

Applicationfi1edJanuary22,1915. Seria1lt'oi3,679., i a a B and the rail,,is a shallow recess 6 eXtendthemain portion or body E preferably cy- I lindrical and having at its basea-flat toe or flange E projecting from one side, which is adapted to lie in the recess 6 and project beneath the ad acent base-flange A". The

in the axial direction as at E to engage the edge of the flange A? and one of the angular faces Z) of the lug, and is adapted to be crowded into the gradually narrowingangular space by the ,endwise movement or body Eis preferably toothed or corrugated creep of, the-rail until it reaches a point at which further'movement in that direction lsimpossible and the rail is thus held and 1 locked'to the tie-plate against further ad-.

. vance relatively thereto.

he rolling member'is held against vertical movement or displacementby'the engagement of the flange E beneath the base-flange A of the rail, and by properly proportioning the body E and the angular faces 6 b of the lug'the body portion will rotate but slightlyv before the locking position is reached and the rail. and lug firmly engaged before such rotation brings the flange E into interfering contact with the lug.

An advantage of the invention is that the recess 6 and lag B with its angular faces may be completed in the rolling operation by which the tie-plate is formed, and further treatment of the latter by milling or otherwise, to provide means for holding the rolling ,memberE FF against vertical displacement relatively to the base-flange and lug, is avoided, thus materially reducing the cost of manufacturing the tie-plate.

The flange E is shown as circular and eccentric to the body E but the, shape and location of such flange may be varied as found necessary or desirable in adapting the inven tion to the conditions under which it may be called upon to serve. V

The double angularity oft-he faces of the lug B prevents the release of the rolling member by a reverse movement of the rail and also serves to hold the latter against creep in either direction; A single inclined face ill serve successfully in holding the rail against creeping strains in one direction.

I claiin-: f

Ina-device of the character set forth, a tie plate adapted to support a rail and having a recess in its upper face, a lug on said plate having an angular face adjacent to such rail, a rolling member having a body portion received in the angular space between said angular face and rail and engaging said lug and the base-flange of such rail,

and having a flange projecting from one side only of saidbody portion, said flange re ceived in said recess and extending beneath 15 the base-flange of the rail to engage the latrolling member. I

In testimony that-I claim the invention ter and prevent vertical movement of said ence of two Witnesses, e
