ANTICREEPER FOB RAILWAY-RAILS.

Specification of Letters latent.

Patented Sept. 2a, 1914..

Application filed. November 6, 1913. Serial No. 799,469.

To all whom it may concern Be it known that I, PATRICK H. MoOoon, a citizen of the United States, residing at Indiana Harbor, in the county of Lake and State of Indiana, have invented a certain new and useful Improvement in Anticreeper for Railway-Rails, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to railroad track equipment and has for its object the provision of improved devices for preventing the creepage of rails longitudinally of the track.

The general purposes of such devices is well knownby those skilled in the art and many devices have been designed to accomplish such purpose, and I will not, therefore, set forth the broad advantage gained by the use of the device of my invention, the invention having for its own purpose the simplification of such devices and a corn struction thereof that will render them more practical.

The device of my invention includes two pieces which cooperate clampingly to engage the base flange of a rail section at the opposite longitudinal edges of the rail section, one of these pieces carrying a projection preferably integrally formed therewith that engages a vertical or upright face of a railroad tie and which extendsbeyond the general plane of the clamping portion toward the tie so as to afi'ord clearance between the clamp proper and the tie. This projection or ear is disposed below the rail and at one side thereof and engages that face of the tie toward which creepage would occur were it not for the device of the invention, the invention being particularly adapted for service in double track systems in which each track is intended to be limited to traflic moving in one direction only. Because of the spacing intervening between the clamp of the structure and the railroad tie and on account of the location of the projection or lug carried by one of the two elements of the clamp at one side of the base flange of the rail,there can be no bodily longitudinal movement of the device of the invention along and with respect to the rail carrying the same since any movement of the rail toward the tie is accompanied by a turning movement or tendency to turning movement of the clamp in the plane of the rail base detail view on a larger scale slrowlng the relationship of the device of my invention to one of the rail sections and the tie as illustrated in Fig. 1; Fig. 3 is a side elevation of the parts shown in Fig. 2; Fig. 4c is a plan view of the parts shown in Figs.

2 and 3; Fig. 5 is a perspective view illustrating the device of the invention, the rail to which the device is applied and the tie against which the device abuts being cut away. more clearly to reveal details of construction; Fig. 6 is a horizontal sectional view illustrating a detail of construction; and Fig. 7 is a perspective view illustrating one of the clamp members.

Like parts are indicated by similar characters of reference throughout the different figures. I

In Fig. 1 I have shown two rail sections a;

of a railroad track which may be supported in any usual or preferred way upon a tie b which preserves the gage of the track: and with respect to which tie track creepage is to be avoided. In some of the remaining figures the direction taken by the normal travel upon the track is indicated by arrows. type employing heads and base flanges that are united by vertical webs. The clamp of my invention includes one member whose intermediate portion 0 underlies the base flange (Z of the rail section a to which the device is applied, the portion 0 extending transversely of the rail (preferably at right angles thereto) and terminating at/its ends in hooks e and 7 which extend upwardly and overlie, at their ends, the outer longitudinal edge portions of the base flange. The hook e is shaped snugly to receive one side of the base flange, as illustrated in Fig. 5, but the hook f is enlarged to receive not only the other side of the base flange but also the complemental clamp member 9 which is The rails illustrated are of the usual desirably provided with upper and lower insetting lips, h, z to form a channel snugly receiving the contiguous side of the base flange. The top of the portion 0 leaves the bottom surface of the flange d where the lip 2 is disposed to afford space to receive such lip. When the clamp member 9 is out of position the space within the hook 7 that is to receive the lip it and the upper portion of the clamp member 9 in line with the lip it permits the one piece clamp member 0, e, f to be located in position about the base flange. The underlying lip z' avoids any tendency to shearing action between the contiguous side of the base rail flange and the underlying portion 0 and alsotakes part in grasping the rail firmly. The portion of the structure 9 which is disposed upon one side of the base flange constitutes a clamp member proper and tapers toward the tie so as to constitute a wedge which will firmly apply the hooks e and 7 respectively directly to the base flange and the clamp member 57 whereby the two clamp members are held in very firm and fixed relation with the I base flange, thewall of the hook f that engages the outer sidejof the member 9 being preferably correspondingly tapered.

After the clamp member 9 has been driven to position the flexible tongue la at the smaller or front end of the clamp member g is hammered back against the front face of the hook f (as indicated in Fig. 5) whereby the clamp member 9 cannot move backwardly to loosen the engagement of the clamp with the rail. The clamp portion a is provided with a downwardly extending projection or lug Z which also extends forwardly of the clamp member into engagement with the tie Z). This projection or ear Z is desirably integrally formed with the larger of the two clamp members and is located to one side of the rail to which the clamp is applied so as to turn or tend to turn the clamp in the plane of the rail base when the rail moves or tends to move toward the tie. Spacing intervenes between the projection Z and the base flange of the rail to enable said projection to perform its function. If the rail should move or tend to move in the reverse direction it is quite apparent that the fixed relationship of the clamp and rail would not be disturbed.

The top surface of the clamp element a is rearwardly extended to afford an extended foot m. A web 12 joins the central vertical portion of the downwardly extending ear Z with the clamp element o and its rear extension m whereby the rail operates through the foot m and the web n to prevent the extension Z from bending to the rear when the ear Zsis pressed against the tie, the material of which the structure is made being preferably malleable cast iron. By means of the foot m and Web n the clamp member a is maintained in exact parallelism with the base flange of the rail so that hooks e and f do not turn in vertical planes. Further to strengthen the structure a rib 0 extends underneath the clamp member 0 and about the exteriors of the hooks e and 7, this rib being cast integrally with the said clamp member and its hooks. The hook e is desirably provided with an additional rib [9 further to strengthen it. The ribs 0 and p are merged in one casting with the web n whereby the web and ribs reinforce each other.

While I have herein shown and particularly described the preferred embodiment of my invention I do not wish to be limited to 'the precise details of description shown as changes may readily be made without departing from the spirit of the invention, but- Having thus described my invention I claim as new and desire to secure by Letters Patent the following 1. An anticreeper for railway rails including two single piece clamp members, one underlying the base flange of a rail and terminating in hooks e f which themselves terminate above and overlie the base flange and which hooks are s aced apart for receiving the base flange t erebetween, hook e being adapted to receive one side of the flange, the space of the second hook f aflt'ording clearance between the upper end of this latter hook and the top of the base flange for purpose of assembly, also clearance between the adjacent side of the base flange and this latter hook to receive the second clamp member, the second clamp member 9 being provided with an insetting lip 72. which overlies said adjacent side of the base flange, said second clamp member being tapered in the direction in which creepage of the rail is to be guarded against; a downwardly extending ear Z carried by the clamp and which extends forwardlyv of the clamp in position to engage a tie and to space the tie from the clamp, said ear being located at one side of the clamp and with spacin between said ear and the base flange 0% the rail to enable turning effort to be exerted upon the clamp when the rail is moved toward the tie, the first clamp member bein rearwardly extended beyond its hook e to a ford an extended foot m, and a brace n joining a central vertical portion of the ear Z with the foot m to prevent the ear Z from bending to the rear when the ear is pressed against the tie.

2. An anticreeper for railway rails including two single piece clamp members, one underlying the base flange of a rail and terminating in hooks e f which themselves terminate above the base flange and which hooks are spaced apart for receiving the base flange therebetween, hook e being adapted to receive one side of the flange, the space of hook f'receivi clamp the second clamp member between the ad aeent sideof the rail base and hook f, this second clamp member being tapered in the direction in which thecreepexsa1d ear being located at one side of the c m with spacbetween it and the base ange of the rail toenable turning efiort to be exerted upon the clam when the rail is moved toward the tie, t efirst clamp member being b the rearwardly extended at and be 0nd the hook e to constitute anextended oot m, and a 15 brace 'n joinin the lower portion of said ear with said oot to oppose the bending of the ear to the rear when the ear is pressed against the tie.

In witness whereof, I hereunto subscribe 20 'my name this thirtieth day of October A. D.,
