ANTIQREEPING DEVICE FOR RAILS.

Specification of Letters Patent.

Patented Mar. 14, 1916.

Application filed March 18, 1914. Serial No. 825,542.

To all whom it may concern Be it known that I, CARL F. Donnscnun, a citizen of the United States, and a resident of Cleveland, county of Cuyahoga, State of Ohio, have invented a new and useful Improvement in Anticreepmg Devices for Rails, of which the following is a speclfication, the principle of the invention be ng herein explained and the best mode in which I have contemplated applying that princlple, so as to distinguish it from other inventions.

The present improvements relating as 1ndicated to anti-creeping devices for rails are particularly adapted to be attached'to the ties upon which the rails are laid and to then engage the rails to prevent the latter from longitudinal movement upon the passage of a train. The prime requisites of such a device are simplicity and security of attachment. The present invention has been designed to provide as simple a construction as possible and one which may be readily attached to the rail.

To the accomplishment of the foregoing and related ends, said invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims.

The annexed drawlngs and the followlng description set forth in detail certain mechanism embodying the invention, such disclosed means constitutlng, however, but one of the various mechanical forms in which the principle of the invention may be used.

In said annexed drawings :Figure 1 is a view in perspective showing a portion of a rail attached to a tie where it is securely held by means of any improved anchor; Fig; 2 is a side elevation of one part of the rail anchor shown in Fig. 1; Fig. 3 is a view in perspective of the locking means for such rail anchor; Fig. 4. is a perspective View similar to Fig. 1 but showing a modified form of the invention; Fig. 5 is an end ele ration of the rail and anchor shown in Fig. 4; Fig. 6 is a bottom plan view of the rail anchor shown in Figs. 4 and 5, and Fig. 7 is a perspective view similar to Fig. 4 but looking down upon the rail instead of up, as in the former figure.

Referring to Figs. 1, 4 and 7, there is shown a portion of the tie 1 upon which rests a rail 2 which may be suitably attached to such tie by the usual track spikes, etc. (not shown). The rail 2 is of the usual construction being provided with a base 3 having the usual laterally extending flanges.

Upon most railroads each track is intended for traffic in a single direction, and consequently the longitudinal thrust upon the rails acts always in the same direction. In time this thrust tends to move the rails longitudinally, and it is to prevent this movement, which has in the past often caused accidents, that the present rail anchors are provided.

Referring now to Fig. 1, the preferred form of my rail anchor will be seen. The anchor comprises a rail-receiving body member, or shoe, 7 which is adapted to rest upon the tie and is provided at one end with a downwardly extending flange 8 which rests against the side of such tie. This end flange 8 is preferably provided with sharpened engaging members or wedges 9 which enter the wooden tie and maintain the body member in its proper position with respect to the same. Two upwardly extending rebent arms 16 are preferably integrally connected to the body member 7, the upper or adjacent ends of such arms being spaced a 7 less distance apart than the width of the base of the rail, thus making it necessary to turn the rail in order to introduce the same between such arms. The upper or horizontal portions 15 of the arms 16 are spaced a slight distance above the base of the rail \bvher; the latter rests upon the bodymem- The preferred type of means for locking the rail to the shoe are shown in Fig. 3. In this figure there is shown a U-shaped loop 18 provided with parallel spaced arms 17 between which there is interposed a pin or plate 19 having a wedge-shaped portion 20 lying just beyond the spaced ends of the arms 17. This pin 19 is provided with a laterally projecting lug 22 and if desired the adjacent faces of the ends of the arms 17 may be beveled slightly as at 21 to facilitate the introduction of the wedge-shaped portion 21 of the pin 19." It will be noticed that the bottom arm of the loop 18 is provided ing the same with respect to'the anchor=7 and the arms 16. \Vhen the locking device shown in Fig. 3 is thus'positioned between. the arm' 16 and the rail base, the head end of the loop 18 is struck a sharp blow thus driving the loop longitudinally along the rail beneath the arm 16; Movement of the pin or plate 19 is prevented by reason otthe projecting lug 22 on the same, which engages against the side of the arm;'16, thus causing relative movement between the loop and the pin and spreading the two arms 17 of the loop by reason of the introduction therebetween of the wedge-shaped portion of the pin 19. The final position of the locking means is shown in Fig. 1. A considerable force is thus exerted upon the rail base by the locking wedge which is held beneath the arms 16, this force being suiiicient to prevent the rail from moving under the thrust of passing trains. In order to prevent movement of the railin either direction, should thetrack be used for traffic in i bcth directions, the anchors may be directed in opposite directions upon adjacent ties.

In Figs. 4 to 7 inclusive I show a modified form of the invention in which the body member 7"of the-anchor is provided with a serrated wedge26 adapted to enter the tie and with a forwardly extending curved wedge 10 adapted to lie-beneath andin contact with the base 3 of the rail. I provide a clamp 4 which may be driven over the rail and wedge 10, such clamp having out-- wardly extending sides 5 and inwardly extending arms 6, the latter beingadapte'd to extend over the rail base 3. The wedge 10 is provided with curved sides 11 which are adapted to beslidably engaged by the slides 5 of'the clamp, thus'centrally positioning such clamp with respect to the rail upon movement of the clamp into its locking position, It will of course, be understood that the'anchors' shown in these figures maybe oppositely directed upon adjacent ties in order to prevent any tendency toward loosening under the action of the passing train.

In most cases the rail anchors will be used on tracks in which the traffic moves in a single direction, in which event-each anchor is tightened by the passage of each train. This feature eliminates the necessity of ill-'- spection of the anchors as the latter when once applied can never become loose except upon reversal of the tra-tfic. I 1

Other modes of applying the principle of my invention may vbe employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means stated by any of the following claims or the equivalent of such stated'm eans be employed.

I therefore particularly point out and distinctlv claim as my invention a In a rail anchor, the combination of a;
