JOHN M. SCOTT, 0F RACINE, WISCONSIN, ASSIGNOR TO OTTO R. BARNETT, OF CHICAGO, ILLINOIS.

RAIL-AN 01103.

Serial No. 513,661.

To all whom it may concern:

Be it known that I, JOHN M. Soon, a citizen of the United. States, residing at Racine, inthe county of Racine and State of Wisconsin, have invented certain new and useful Improvements in Rail-Anchors, of which the following is a specification.

My invention relates to a device for preventing the longitudinal creep of railroad rails, devices of this sort being commonly called rail anchors, rail stays or anti-creepers; and the invention has for its object to provide a device of this character of novel construction which will be an improvement in several respects upon the rail anchors now in use.

More specifically the invention has for its object to provide a form of rail anchor which will dispense with all nuts, bolts, wedges or other parts of that sort which are likely to become loosened or displaced; thereby providing a rail holding device which will be positive in its action.

The invention is illustrated in a preferred embodiment in the accompanying drawings, wherein- Figure l is a plan view of a portion of a rail and ofthe tie on which it rests, showing the rail anchor of my invention in place upon the rail. Fig. 2 is a sectional View taken on line 22 of Fig. '1, looking in the direction of the arrows Fig. 3 is a view in perspective of the jaw member of the device. Fig. 4 is a fragmentary plan View of the de* vice illustrating the way in which the device is put upon the rail. Fig. 5 a similar view with the parts adjusted to their rail gripping position. Fig. 6 is a side elevation -of the jaw member.

Like characters of reference indicate like parts in the several figures of the drawings.

Referring to the drawings, A represents a rail having a base or flange B; C a tie supporting the rail to which the rail is secured by the usual spikes D, D. I

The rail anchor consists of a jaw member E and a strap F, the jaw member being K. The horizontal web I is preferably formed with the projection L, reinforced by the strengthening web M. The jaw member is preferably made of malleable iron and I preferably set into its jaw the hard steel block N having the teeth 0 which bite into the top and edge of the rail base. The overhanging web J may be formed with the ears P which can be hammered down upon the in-set block N to keep the latter from falling out of the jaw and getting lost before the device is put upon the rail. v

The jaw member E is clamped against the rail base by means of the strap F which is preferably made of heavy spring steel and hook R at the other end which engages the opposite edge of the rail base, this latter hook constituting a jaw opposed to that of the jaw member. Obviously the means whereby the jaw member E is clamped to the rail might consist of. more than the one part shown. I believe, however, that the simple integral strap F together with the jaw member of the construction shown is suflicient to the effective operation of the device.

The strap, it will be seen, stands away from the-tie C. If, therefore, the device is adjusted on the rail base so as to take a considerable hold thereon, the creep of the rail in the direction indicated by the arrow in Fig. 1 will cause the end of the strap F which is in contact with the rail base to travel therewith; that is, it will cause the strap to be turned or rocked with the point of its engagement with the jaw member E as a pivotal point. If the surface engaged by the hook Q of the strap member were smooth, this turning of the strap member wbuld tend to cause a slip between the hook Q and the jaw member and so defeat the Specification of Letters Patent. Patented une 20, 1911. Application filed August 19, 1909.

purpose of the device. To prevent this the jaw member is formed with a notch S which is preferably oblique relative to the edge of the rail base, this notch constituting a shoulder T against which the hook Q will squarely abut when the strap F is turned to the proper angle, (Fig. 5). When this is done it will be seen that the strap is fulcrumed at a definite point on the jaw memher, so that it cannot be disengaged from the jaw member by a further rocking movement caused'by the creeping of the rail. The tendency of the rail to creep is, therefore, checked, since a forward movement of the hook R increases the lateral grip between it and the opposed jaw of the aw member. The notch S constitutes a surface U with which the hook Q engages and which prevents the hook Q from movement toward the tie.

In applying the device, the jaw member is placed against one side of the rail base with the web G abutting against the tie. The hook R is then hooked over the opposite side of the rail base and the hooked end Q of the strap F-is swung over the tapered end K of the jaw member. In this position the hooked end B of the strap is preferably at a point opposite to the notch S on the jaw member, so that the hooked end Q of the strap may be swung toward the web (3r, the bearing of the hook It against the raihserving as the pivotal point. In "the preferred embodiment of my invention the inner face of the hook Q is preferably ta pered so as to facilitate forcing the hook Q over the shoulder T. By properly proportioning the parts the device may be applied in this manner even when the strap is made of malleable iron or similar material, but when the strap is made of spring steel the parts may be fitted togethermore closely, so that whenthe end Q is driven over the shoulder T the end Q will spring slightly as is passes the shoulder T. AV hen the end Q has reached this position the end B is then driven toward the tie, the bearing of the hook Q upon the jaw member serving as the pivotal point, and this swinging of the strap F to a position diagonal of the rail as shown in Figs. 1 and 5, brings the hook Q to a position where it squarely abuts against the shoulder Tand is seated in the notch S. To further facilitate the application of the device as well as to increase its grip upon the rail, the inner face of the hook R is toothed as shown (Fig. 1), so that the hookR may be more readily forced lengthwise of the rail toward the tie and yet will more effectively engage the rail flange so as to resist any tendency of the rail to slip through hook It, with the result that any tendency of the rail to creep will carry the hook R farther. toward the tie, thereby increasing the grip of the device upon the rail. If desired, the jaw member E may be so constructed as to have a smooth surface engaging the rail flange, so as to facilitate this action. V

. In removingthe device from the rail the hook it is driven away from the tie, causing the hook Q topivot on its edge nearest the tie, when the preferred embodiment of my invention is used, so that the edge of. hook Q farthest away from the tie will assume a positionin which it tends to ride over the shoulder T. When this position is reached the hook Q may be readily driven over the shoulder T and the device" removed.

devices, constructions and arrangements shown and described as modifications might be devised which would come within my invention as defined by the claims.
