Specification of Letters Patent.

Patented Jan. 2, 1906.

Application filed Time 24. 1905. Serial No. 266,717.

To all 7071/0711 1'1 'ITMY/I/ concern:

Be it known that I, J ENS J ORGENSEN OVE FIsoHER, of Racine, Wisconsin, have invented an Anticreeping Device for Rails, of which the following is a specification.

Y This invention relates to devices for gripping the rails of a railway-track to hold them against the longitudinal movement known as creeping, which, as is well known, is caused by heavy travel over the track and is of general occurrence where some means is not taken to prevent it.

The object of my invention is to provide a device for gripping the rail and holding thereto with sufficient force to prevent any longi tudinal movement and a device superior in cheapness and efficiency to devices which have been heretofore invented and one which can be applied at any point of the rail and does not require any notches, holes, or other means of attachment requiring special shaping of the rail.

My device consists, briefly, of a jaw or pair of jaws adapted to fit over the flange of the rail and provided with knife-edges which bite into the metal of the rail when the device is driven into position and means for holding serious objections to the use of such devices by reason of the amount of attention required to keep the nuts thereof screwed up tight, as is we 1 known to railway-men.

My invention will best be understood from the following description, reference being had to the accompanying drawings, wherein- Figure I is an end view of a rail, showing an anticreeping device according to my invention secured thereto. Fig. 2 is a side view of the same. Fig. 3 is a perspective view of the clamping-j aw. Fig. 4 is an end view of a rail having a pair of jaws secured thereon; and Fig. 5 is a similar view, partly in longitudinal section, of a modified construction whereby a bolt is used in connection with my improved jaws in place of the improved key-fastening shown in the other figures of the drawings.

The principal element of my invention consists of the clamping-jaw, (designated A in the drawings,) said jaw consisting of two lower members 11, having upper faces 12, parallel to the bottom of the rail-flange, and an upper projecting member 13, having a lower face 14 parallel to the upper face of the rail-flange. In each of the lower members 11 is set a knife of chilled iron or hardened steel 15, which has an edge 16 projecting slightly above the face 12 of the member 11, and in like manner there is set in the upper member 13 a knife 17, which has an edge 18 projecting from the lower face 14 thereof. The member A is preferably a casting of malleable metal having recesses cast therein to admit the knives 15 and 17, which are of angular (herein shown as square) section to prevent them from rotating in their sockets. A tab 19 is left at the edge of the recess forming the socket of each of the knives 15 17, said tab being cast in erect position, as shown at the right of Fig. 3, and subsequently hammered down over the ends of the knives 15 17 as shown at the left and top of Fig. 3, to prevent said knives from falling out of their sockets. i

In Figs. 1 and 2 is shown a rail 20, having a flange 21 and seated on a tie 22, and spiked thereto by means of a rail-spike or other fastening 23. The member A is driven over the edge of the flange 21 by a sledge-hammer applied to its rear face 24, causing the knifeedges 16 18 to bite into the metal of the rail. In connection with the member A is used a member B, which consists of a bar having a hook 25 at one end, which engages the opposite edge of the rail-flange 21, as shown, and the other end of the bar B is passed through a hole 26 in the center of the member A and is provided with a slot 27, through which is inserted a tapered cotter C, which, being driven down, causes the hook 25 and member A to be drawn up firmly and the knife-edges to bite more deeply into the rail flange. In the member C is bored a row of holes 28 and when the member is driven down as far as possible a split pin 29 is inserted in the uppermost hole, which projects below the slot 27 and the ends thereof expanded, as shown, to prevent the member 0 from coming loose. The member A is provided on each side with an abutment-face 30, which may be braced on the interior by a bracket-rib 31, one of the key-fastening B or B.

faces 30 being set to abut against the side of the tie 22. (See Fig. 2.) Also to enable the knives to cut more readily into the metal of the rail-flange the outer ends of the edges 16 18 may be slightly beveled, as shown at 16 and 17 In Fig. 4 is shown a somewhat different arrangement, two of the clampingjaws A A being employed and being joined together by a round bar B, having a head 32 on one end and a slot 27 in the other, through which is passed the cotter C and secured therein by the split pin 29, as before. The aws A A are similar to the jaw A, except that each is provided with but one abutment-flange 30 30". Whether one or two abutmentflanges are used will of course be a matter of convenience, it being understood that when one face only is used the double arrangement of Fig. 4 requires two separate patterns for the jaws, having the flange on their right and left sides, respectively. Fig. 4 also shows how this arrangement may be made effective for different-sized rails without changing. the length of the connection B, the latter being made sufficiently long' for the largest-sized rail, and one or more washers 33 or blocks 34 being inserted between the member A and cotter 0, according to the width of the flange 2 1, and the same device is also applicable in case the cotter C gets driven too far down in the slot or in case the bolt B becomes elon-- gated by use. 1

In Fig. 5 is shown how myimproved clamping-j aw may be used with an ordinary bolt B, having a nut 35, instead of my improved While I consider the key-fastening preferable, my invention is not limited to it, and it will be readily understood that other means for causing the clamping-j aw to grip the rail-flange may be used or might be devised without altering the principle of said jaw. When a bolt is used, as in Fig. 5, a snug 36 may be cast on the member A, which prevents the head of the bolt from turning while the nut 35 is being tightened up.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In an anticreeping device for rails, the combination of a j aw having upper and lower members adapted to grip over the edge of a rail-flange, a piece set in said j aw transversely to said flange adapted to bite thereinto, and means for holding said jaw against longitudinal motion.
