To all whom it may concern Be it known that 1, JOHN F. SENTER, a.

citizen of the United States, residing at Tacoma. in the county of Pierce andStat'e of Washington, have invented a new and useful Anticreeping Be ce for Railway- Rails, of which the follow a specification. I

This invention has reference to anticreeping devices for railway rails, and its object is to provide a device which may be attached to a rail in such manner as to engage a'tie-and thereby prevent creeping of the rail. 4

In accordance with the present invention there is provided a plate-like structure with means for clamping it to the rail by engagement of the structure with the basic flange oi' the rail on opposite sides of the preventing creeping in one direction is suiiicient. In single track roads or where the traffic is in both directions, provision must be made for preventing the creeping'ot the trackin either direction.

In accordance with the present invention there isiprovided a device which will prevent the track from creeping in one direction, or by a slight modification of a portion of the structure the track is prevented from creeping in either direction. However, the structure preventing the-creeping of the track in one direction. only is more readily attached to the rail and is conse quently advantageous for use in connection with double track roads.

Since the anti-creeping device must withstand heavy strains and the rail and anticreeping device must be fastened together in a permanent manner, although readily releasable one from the other at will, the present invention contemplates means for securing the anti-creeping device and ra l together which will embed in the basic flange of the rail to an ex ent to overcome all tendency of movement of the rail and anti-creeping device one on the other.

The invention will be best understood from a consideration of? the following deitailed description, taken in connection with the accompanying drawings forming part of this specification, with the further understanding that while the drawings show a practical form of the invention the latter is not confined to any strict conformity with the showing of the drawings, but may be changed and modified so long as such changes and modifications come within the scope of the appended claims.

In the drawings: Figure l is a crosssection of a rail showing the anti-creeping device in elevation and in operative relation to the rail. Fi 2 is a plan view of the structure or" Fig. 1 showing the relation of the and-creeping device to a tie. with the rail indicated in dotted lines and the locking member of the anti-creeping device partly in section. Fig. 3 is a bottom plan view of the anti-creeping device structure shown in Fig. 2. Fig. l is a section on the line H of Fig. 2 with the rail in place. Fig. 5 is aperspective view of a gripping block forming part of the anti-creeping device. through another form of vice applied to the rail. Fig. 7 is a plan view of the structure shown in Fig. 6 with the rail omitted and a portion of the gripping blocl; housin in section.

lhe structure or Figs. 1 to 5 is that of one form of gripping device. while the structure of Figs. 6 and T is that of another form of gripping device diii'erent in some respects from that of the precedin figures. The gripping device shown in Figs. 6 and T is shown and described more in detail and specifically claimed in application No. 30,617. filed by me on May 26. 1915, while the gripping device in its broader aspects is claimed herein, and the structure of Figs. 1 to 5 is specifically claimed herein since it is neither shown nor described in the aforesaid application.

Referring first to Figs. 1 to 5 there is shown a plate-like basic member 1 with a side offset 2 near one end having a rightangular flange extension In the installed position of the plate 1 the flange 3 is pende t, and is extended lengthwise of the plate it so as to provide a broad bearing face to engage one side of a tie at. The end of the piate 1 near the oiiset 2 is formed with a return bend 5 rising from and overhanging the corresponding end of the plate to constianti-creeping detute a laterally extended hook shaped to embrace one long edge of the basic flange 6 of arailway rail T. The return bend or hook 5- is provided with terminal strengthening flanges S curved similarly to the curvature of the hook 5 and continued under the plate 1, considering the plate as in the installed position, while the flange 8 adjacent to the flange 3 merges thereinto. The plate 1 tapers toward the end remote from the hook 5 and on its under face is formed with a longitudinal strengthening -web 9 having at one end a continuation 10 joining and strengthening the flange 3. At the narrow end of the plate 1 there is provided a housing 11 rising above the upper surface of the plate 1 and formed with a through passage 12 open at both ends with the passage directed toward the return bend but displaced with respect to the hook toward that side of the plate 1 provided with the offset The passage 12 through the housing 11 is deepened so as to extend a short distance below the upper surface of the plate 1 and the deepened portion of this passage is furthermore prolonged into the plate 1 beyond the housing and toward the hook 5,

as indicated at 13. Extending transversely Fig.

through the housing is another passage 1% with one side, which may be the side toward the hook 55, substantially perpendicular to the length of the passage 12. while the other side tapers in order to accmninodate a taper key 15 designed to enter one end of the passage 1 1 and extend through the other end. Adapted to the passage 12 through the housing 11 is a gripping block 16 shown in 5 as of generally rectangular form so as to quite snugly fit the passage 1:2 which may also be of rectangular form. 'The block 16 is somewhat longer than the housing so that both ends of the block may be exposed at the corresponding ends of the housing. One end of the block is designed to engage the corresponding edge of the flange (3 of the rail 7 and may, therefore, be termed the jaw end of the block. This jaw end is provided with a series of teeth 17 elongated in a direction up and down of the block when in its installed position and the upper portion of the jaw end is provided with an overhang 18 into which the teeth 17 extend at an acute angle to thefirst-named portion of the teeth, whereby, as will hereinafter appear. the teeth serve to engage the side edge of the base flange of the rail from top to bottom thereof. As shown the teeth 17 are of tri angular cross-section, but, of course, they may be made of any other suitable shape and are of suflicient length to extend entirely across the corresponding edge ofthe rail flange and above and below it. he block 16 has a transverse passage 19 through it adapted to receive the key 15.

The anti-creeping device is applied by placing the plate 1 underneath the flange of the rail with the hook 15 engaging over the corresponding edge of the flange and then the block 16 is introduced into the housing 11 through that end of the housing remote from the rail. Since the bottom of the passage or channel through the housing is below the level of the bottom of the rail flange in the applied position of the anti-creeping device, the teeth 17 extend below such flange, because the block travels on the bottom of the passage 11! At the same time the overhang or nose 18 of the jaw end of the block 16 is above and in overhanging relation to the corresponding face of the rail flange. Xow by delivering one or more blows to that end of the block 16 projecting through the end of the housing remote from the rail the teeth 17 are caused to sink into the edge of the flange of the rail for an appropriate distance. A hammer or sledge may be used for delivering the blows the block 16 being long enough to provide an accessible end beyond the housing.

'ith the teeth sinking for a distance into the edge of the rail flange there is provided a grip by the gripping block upon the rail flange which is elf ectively resistant to any creeping tendency of the rail. for when the anti-creeping device is installed the flange 3 is abutted against a suitably placed tie Jr and the latter being lodged in the road ballast constitutes an effective resisting means to the creeping tendency. The wedge key 15 when driven into place effectively locks the block 16 in the housing against any liability of loosening. and as the wedge key may be of slight angle the liability of loosening is reduced to a negligible minimum. although. of course any suitable means for avoiding even such slight liability may be used. If under any conditions which may arise it becomes desirable to remove the anti-creeping device, it is only necessary to dislodge the key, whereupon but little force is needed to remove the block 16 and so release the anticreeping device. The rail flange is gripped on opposite sides by the hook 5 and block 16. respectively. and as the nose 18 of the block is in overhanging relation to the rail flange. the anti-creeping device is sustained by the rail. The plate 1 is of a nature to permit its application to the rail'wi'th the plate underneath the rail and the flange 3 against the; tie at any time and without in any manner disturbing the rail.

In Figs. 6 and 7 there is shown a plate 20 of substantially rectangular form and of a. width which may be considerably greater than the width of the plate 1 and in fact may be about as wide'as a tie. The plate has its undersurface formed with ridges 21 which, when the plate is applied to a tie, will bite into the tie, and by making these ridges of herringbone form as shown and described in the aforesaid application liability of splitting the tie is eliminated. At one also near the other end of the plate areend the plate 20 has on the surface remote from the ribs 21 a return hook 22 corresponding generally to the hook 5 and for a similar purpose, but the hook 22 may be of less extent lengthwise of the rail than the passages 24 through the plate designed to be traversed by railroad spikes, whereby the plate 20 is made fast to a tie with the ribs 21 embedded in the surface of the tie, so that the plate 20 becomes locked to the tie, and, therefore, is able toresist any creeping action of a rail made fast to the plate. In Fig. 6 there is shown. a rail 7 with a basic flange 6 like the showing of the other figures.

At that end of the plate 20 remote from the hook 22 is a housing 25 provided with a passage 26 lengthwise therethrough and'a transverse passage 27 like the passages 12 and let of the form shown in Fig. 1 and associated having-a tail piece 29 producing a shoulder The passage 26- has a deepened portion'28 similar to the deepened extension 13'of the passage 12.

. In the structure of Figs. 6 and 7 a key 15,

25 and a block 16 might be used, but instead of such a block there is provided a block 16 where joiningthe block 16 The tail piece 29 takes the place of that part of the block l6 provided with" the passage 19 and constitutes a means whereby a hammer blow may be delivered to the block 16 The' gripping block 16 has teeth 17 and a nose end 18? like the parts 17 and 18 of the gripping block of the preceding figures.

A structure such as shown 'in Figs. 6 and 7 is applied to the top of a tie being there fastened by spikes extending through the uoles 24 with the additional fastening means provided for by theribs 21. Thejplate 20 with the rail secured thereto in the same manner as in the structure of Fig. 1 and associated figures is proof against creeping of the rail in either direction and is useful in some situations. However, the plate 2Ov cannot be applied with the ease of the plate 1, since it must be introduced between a rail and an underlying tie. The plate 1 or the plate 20 e'achwith its hook and hous ng and other structural parts may be a single casting.

The gripping blocks 16 or 16 may each also be a single casting, while the Wedge 15 must, of course, be a separatepiece. It follows, therefore, that but three pieces are needful and these three pleces when appl1ed to a rail effectively lockthereto against any.

liability of the rail creeping with respect to the ties with which the anti-creeping plates engage.
