Application filed June 13, 1910. Serial No. 566,555.

In all win/m 2'2 may concern Be it known that I, RIPLEY N. BAi'LIEs, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Rail-Anchors, of which the following a full. clear, concise, and exact, description, reference being had to the accompanying drawing, forming a part of this specification.

My invention relates to rail anchors and particulzwly to that type of rail anchor or anti creeping device in which there is a wcdgil'i action under the rail and in which longitudinal movement of the rail is prevented by jaws or clips which embrace the iianges of the rail and are so disposed with reference to one another and with reference to the adjacent. cross-tie that any tendency of the rail to creep, causes a twisting or rotative movement of said jaws as a whole, whereby they grip the flanges of the rail even more firmly and by cooperating with the cross-tie or other, stationary member, prevent creeping.

One of the objects of the invention is to provide a rail anchor which may be readily applied to a rail, which shall automatically tighten on the rail. upon any tendency to creel"), and which is provided with auxiliary means such as a keeper, for increasing its grip on the rail by a wcdging action under said rail, in addition to the normal twisting tcmlency, which keeper shall prevent said rail anchor from releasing its grip on the rail and working loose owing to repeated yil'irations when the rail anchor is withdrawn from inm'iediate contact with the tie-, :is sometimes occurs owing to the rearward movement of the rail.

ll hile my invention may assume a number .of forms, I have illustrated in the accompanying drawings a convenient and practicalembodiment of the idea.

construction.

My rail anchor comprises broadly,a main gripping portion A for resisting the creeping tendency of the rail, and an auxiliary binding means or keeper B. The main portion A comprises essentially, in the preferred construction, a base member, bar or plate 1, adapted to pass beneath the rail and provided at opposite ends with clips or Qand 3. An oflset projectingarm 4 is provided at one end for engagement with a side of a tie, and a locking arm or projection '5 extends from the opposite end to cooperate with the member B.

Jaw 2 is preferably provided with reinforcing ribs or flanges (E -G, while the jaw is similarly provided with reinforcing ribs 77, although I do not limit myself to this The portion of the jaw 2 which is adapted to grip an outer flange of the rail is arranged at a slight angle to the longitudinal axis of the device as a whole, as shown particularly at 8, Figs. 1 and 2. The end of the clip member 2 which extends over and above one flange of the rail, terminates at 9 in an edge also arranged diagonally of the device as av whole, for a purpose hereinafter described. The other jaw 3 has a vertical wall portion 10, part of which is adapted to bear against. the outer edge of the other flange of the rail. A reinforcing rib 11 is shown in the preferred construction in connection with clip member 2. The arm 5 is also preferably provided with a reinforcing rib 11, the end of said arm 5 being enlarged at 12, having its under surface beveled at- 13, so as to present a substantiallywedge shaped appea rance; It should be noted that clips 2 and are not opposite each other, but are arranged in staggered relation.

Although it may be located centrally or nearly so, nevertheless in the preferred construction which is the one iilustrated, it will be seen that the tie-engaging projection t arranged at one side of the structure so that the creeping tendency of the rail will cause a twisting or rotating movement of the rail anchor as a whole, as hereinafter described. The downwardly extending portion 4 may be ln'ovided with a suitable reinforcing rib l-l. It will also be apparent that the various reinforcing ribs described in connection with the clips 2 and 3 and elsewhere are continned across the base member 1 for a considerable distance in order to suitably stiffen the inner wall 8 of clip member necessary wi thout weight.

The auxiliary member or keeper B con sists preferably of a bar 1:") having at one end a c ip member 16 and at the opposite end a (up member 17. Clip member 17 is provided with an undercut portion 18, to facilitate the placing of said member on a rail. The clip members are preferably reinforced by ribs 19 and 20 respectively, al-

strength unnecessary though I do not limit myself to this construction. A portion of the bar 15 is depressed or cut away to an inclined or beveled surface 21, as shown particularly in Fig. 4. The vertical wall 22 in' which this surface terminates at one end, is diagonally disposed with respect to the length of the bar 15 and said wall is also slightly rounded, as clearly shown in Fig. 2. The beveled surface 21 is adapted to cooperate with the wedging surface 13 on the extension 5 of'member A..

The method of applying the members to the rail and tie is as follows: The member A is first placed beneath the rail with the projecting arm 4 adjacent to a cross-tie, and with the clip member 3 embracing one flange of said rail, the member as a whole being twisted from its normal'position, so that a line connecting the clip members 2 and 3 would be substantially at right angles to the length of the rail. In this position, the diagonal edge 9 of the clip member 2 is parallel to the opposite flange of the rail, the distance between the clip members being such that this'edge 9 will just clear said rail .flange and may be lifted up above it and driven around by blows until the jaw as a whole begins to take hold of said rail flange. By driving clip member 3 toward the tie, the entire structure A will be swung around to approximately the position shown in Fig. 2, with the rail flanges well within the clip members 2 and 3 and firmly held thereby. When properly applied, the outer edge of one rail flange should bear againstthe forward half of the inner wall 10 of the clip 3, and the outside edge of the other rail flange should bear against the forward portion of The arm 4. at this time, will bear against the rear side of the adjacent tie. It is obvious that a firm bearing of this arm 4: against. the tie may be had by driving the member A toward the tie during the act of driving the clip members into firm engagement witlrthe rail flanges. The keeper B is now applied to the rail adjacent to the member A, by passing said keeper l3 inuler the rail, and slipping the under-cut portion '18 of the clip member 17, loosely over one flange of the rail, so that the other clip member 16 may be lifted al o ve theopposite flange and made to the device as a whole and to give it thel in the position shown in Fig. 1, leaving conflanges of the rail, is now slipped down toward 'member )1. until the wedging surface 13 thereof engages the beveled surface 21 on the keeper B, whereupon the curved vertical wall 2 will be brought into engagement with one side of the projecting arm 5. it will now be apparent that by driving the member B toward the member A, the various cooperating engaging surfaces will be brought into firm engagement with each other, the enlarged head 12 of the extension 5, causing the keeper to grip the rail flanges, said enlarged head being fi'rn'ily wedged under the rail, the vertical wall '22 having the effect of wedging the lever arm 5 to the right under the rail, as shown in Fig. 2, which wedging movement results in a still further tendency of the member A to twist or turn, thereby increasing the frictional hold of said member on the rail and locking said member under the rail, in its most effective position.

It will be apparent that the keeper l3 tends to partake of any initial creeping movement which the rail may undergo, and thereby increases its wedging grip under the rail as well as exerting a side leverage on the arm of the member A under the rail, to increase the grip of said member on the rail flanges and prevent said creepin In addition to this effect and independently thereof, the main membecA takes a firm hold of the rail flanges and tends to twist or turn to increase its grip on the rail flanges due to the offset arrangement of the clips 2 and 3 cooperating with the arm 4: which abuts against a tie. It will be further apparent that the member B acts as'a lock for member A and prevents the same from twisting or jarring loose from the flanges of the rail, even when said members A and B, as a whole, are moved away from the tie, so that the grip of both members A and B and the relative position of the parts is maintained under these circun'istances also. lVh-en the interlocked parts are again moved forward against the tie, due to the creeping of the rail, there is no lost motion or slipping of the rail with respect to the rail anchor, as the parts'are already in firm engagement with the rail flanges, so that the obstruction offered by the tie, prevents further movement of the rail.

Tn the modifications shown in Fig. 5, the enlarged head 12, of the member 5, has its under surface 15) inclined or beveled in two directions instead of one, longilndiinilly and transversely, the remaining portions of the device being the same as in the figures described above.

in Fig. 6 there shown a modified form of keeper adapted to cooperate with the keeper B, the position of this part being shown. in dotted line section in Fig. (3; As

the keeper B is driven toward the part A in order to increase the wedging action due to the longitudinal bevel of the surface 13, there will result also a wedging to one side of the lever. arm 5, due to the vertical shoulder 22, in the manner heretofore described. This increasing wedging movement of the member 5 .will cause the surface 13 to ro tate slightly with respect to the cooperating beveled surface 24, in addition to its longitudinal motion with respect thereto, whereby in addition to the longitudinal wedging under the rail. there is also a transverse wedging under the rail, due to the tendency of the more distant parts of the member 12 to ride up or move to the right of the inclined surface 24, as will be apparent from Fig. 6. The result is a still further increase of the frictional hold of the anchor on the rail.

In the modifications shown in Figs. 7 and 8, the lever arm 5 extends diagonally of the rail in the opposite direction to that shown in Fig. 2 and it's enlarged head 12 is also provided with a wedg'ing surface 13 which surface however, slopes in a. reverse direction to that shown in Fig. 2. As clearly shown in Fig. 8, the wedging end 12 is largest at the most distant point and is gradually reduced in thickness toward the main body of the portion A. The keeper I3 is similar in all its essential features to thatshown in Fig. 2. except that the vertical wall 22 isinclined in the reverse direction to that shown in said figure, in order to cooperate with the side of the head 12, and, of course, the surface 21 is inclined reversely to cooperate with the wedging end 12.

In order to assemble these modified parts, the main member A is applied to the rail in the same manner as in the preferred con struction already described, and the keeper B is also applied in the same manner except that it is slipped on to the rail adjacent to the body of the main member A and then driven away from said member instead of toward it. As a result of this movement of the part 13 away from the part A, the entire part A is turned or forced around to increase its grip on the rail flanges in the same mannor as in the preferred constrnctirm. One difference between this modified arrangementand the preferred constructioi'i. is that on initial creeping of the rail. the member 3 may move toward the member A a short distance. therebv tending to relax the pressure on the vertical shoulde- 22 against the side of the head 12. llv driving both members A and I) very firmly into position however, at the time they are applied to the rail. this effect will be very slight. One ad: vantage arising however. is that the keeper B. even if it loosens its hold of. the rail, will be confined between the end of the main body portion of the member A and the end. of the enlarged head 12, so that it will.prevent said main member A from dropping from the rail.

Inasmuch as the invention is susceptible of various modifica'tions. I desire not to limit myself to the details of construction and the forms illustrated and de,sciil' e(l. as these particular features were selected simply for the purpose of illustrating a. few of the many possible embodiments of the idea.

Having described my invention. what I claim and desire to secure .by Letters Patent of the United States, is I 1. A rail anchor comprising two parts,

.one part having means so disposed with respect to the rail. and cross-tie as to prevent creeping of the said rail independently of said other part being adapted to maintain such engagement.

3. In combination, means for frictionally engaging opposite flanges of a rail to prevent creeping thereof and additional rail engaging means for increasing said frictional enga ement, said first means alone being capable of prevei'iti'ng said creeping.

4;. In combination. means for frictionally engaging opposite flanges of a rail to prevent creeping thereof and additional rail engaging means having positive engagement with said first means and frietionally secured thereto to lock it in position.

5. In combination, offset means for engaging opposite flanges of a rail and offset means for engaging the adjacent cross-tie whereby initial creeping of said rail tends to incr ase the frictional engagement of said parts and additional means for still further increasing the frictional engagement of said parts, and additional means for locking said parts in position.

7. A rail anchor comprising ottset means for en az asii'ig opposite flanges of a rail and means at one side of said anchor for engaging the adjacent cross tic, whereby initial creeping-(it said rail tends to increase the frictional engagement of said parts, and. detael'iable means for locking said parts in position.

it rail anchor comprising ofii'set means for ei'igaging opposite flanges of a rail and means at one side of said anchor for engaging the adjacent cross-tie, whereby initial creeping; of said rail tends to increase the frictional en agement of said parts, and additional rail engaging means trictionally held in place by citiiiperating with said rail anchor and locking said anchor in place.

9. A rail anchor con'iprising a plate adapted to extend beneath tne rail, jaws at opposite ends of said plate adapted to frictionally engage the opposite flanges of a rail, a downwardly extending; arm at the front of said plate for engagement with a tie, an arm extending diagonally from the rear of said plate and provided with an enlarged end portion, an inclined surface on said end port-ion adapted to cause a wedging action underthe rail, an auxiliary rail clamping member COIHDllSlIlQ a bar extending beneath the rail and having integral clip members at opposite ends for engagement with the flanges of said rail, an under-cut portion adjacent one of said clip members, said bar having a cut-away portion whereby a shoulder formed thereon, said cut-away portion cooperating with said inclined surface beneath the rail to wedge said anxiliary member to the rail, said shoulder cooperating with said diagonal extension whereby movementof the said auxiliary member along the rail, causes an increased gripping of the rail by said auxiliary member-and by said plate and jaws, due to the double wedging taking place under the rail.

In witness whereof, I have hereunto subscribed my name in the presence of two witnesses.
