Application filed October 11, 1923; serm No. 667,875.

To all whom it may concern:

Be it known that I, GEORGE W. WILLIAMS, citizen of the United States, residing at Elm City, in the county of Wilson and State of North Carolina, have invented certain new and useful Improvements in Railway-Tie Shifters, of which the following is a specification. 3

This invention relates toflcer'tain new and useful improvements in railway tie Shifting devices and has particular reference to a rail clamp adapted to form an abutment for a jack en'iplo'yed in shifting railway ties longitudinally of the rails to their proper position:

The primary object of the invention is to provi'dea railway clanip of the above: kind which embraces the desired qualities of simplicity; durability, and elliciency in operiitldn:

Another object is to provide a-rail clamp of the above kind which has jaw members so formed and related as to effectively prevent slipping of the clamp longitudinally of the rail and to prevent downward tilting or displacement of the clamp bodily upwardly" relative 'to or from the. rail, accidentally, while permitting ready removal of the clamp from the rail when manually tilted upwardly;

Another object is to "generally simplify and improve rail clamps of the above kind, whereby the same may meet with all of the requirements for a successful commercial use.

Other objects will appear as the nature of the invention is better understood, and the same consists in the novel form, combination and arrangement or parts 'hereinafter more fully described, shownin the accompanying drawings; and claimed.

In the drawing, wherein like reference characters indi'cate corresponding parts throughout the" views":

Figure lis a framentarytop plan-view illustrating-a tie shifting device embodying a rail clanip constructedih accordance with t'hep'resent invent-ionand operatively related with a rail and: tie;

Figure 2 is a sideelevatidnial view of the rail clampshowfi in Figure 1, drawn on a larger scaleand shown op'e'rati'vely engaged with the rail, and

Figure 3 is a View similar to Figure 2,

' showing the" clamp as' it appears partially engaged with the rail to illustrate ner ofapplying the clamp. I 4

In the form of the invention shown in the drawings, the clain embodies a single sheet of suitable niatria' :such as steel, formed to the manprovide a body portion 5 having. relatively shallow rectangular socket 6 mopposite sides -there'of and provided upon one end with mtegral jaws 7 and 8, the angular jaw 7 being ,h-fangultr form ;so. as to ektend across the ball of the tail 9 as shown in Figure 2, andto depend at' 'thejarther side of the ball-of. the rail. when applied. .1 1

The innerjaw giprojzcts downwardly and inwardly below the; outer jaw/T; and' the upper portion of the face ofthajaw 8 which is opposed to the face ofthe dependingpor't'ion of the jaw -7 conform to and lie closely adjacent opposite sides of the ball of the rail Q'Wl'ienthe clanip is appliedas is also shown-in Figure 2, wherein the innersui'face' of the upper horizontal portion of the'jaw 7 isdi'sposed upon the top of the bar of the rail. 7

The lower end-ofthe depending arm of the outer jaw 7 is pr'ovitledwith a transversely extending arc'uate recesslo in which the adjacent lower corner portions of the ball of the rail may engage when the clamp is tilted upwardly as shown in Figure 3, for thus forming a fulcrum about which the clampis tilted.- The projecting lower' portion of the inner jaw 8 has its inner .face curved or of arcuate form as at 11, and the center of curvature of the face 11 is at the fulcrum point furnished by the arcuate re- In' applying the clamp to the'rail 9, the jaw 7 is engaged with the ball of, the rail so that a lower corner of the ball of the railis'seatd' within the recess 10, as shown in Figure 3; Thehlamp isthntilted-downwardly in the direction of the arrow (1 as is permitted by the arcuate face 11 forming a clearance for the opposite side of the ball of the rail, and then the; clamp is shifted slightly in a, horizontal? directionio i transversely ofthe rail to brir'fg th loweieri'd of" the ja-w 8 into contact with the, wehr of the rail as shownin- Figure: 2,. Whei t;hus" disposed-,'- thelower end' of the depending arni of the jaw 7 is disposed-beneath ohe side of the ball of the rail and the upper end ofthe inwardly projecting lower. pintion or the jaw 8 is disposed" beneath" the E In!" -.as aboveivdescribedwand as shown in F igure 1, at one side of the -tie12 to be shifted. Any-suitableformiofjacki13 is then placed between. adjacent sides-of theclamp and the/tie 12 with the. base act the jackHengaging'thetieas at. 14 and with the head -15 of athe jack engaged in the socket 6 iniithe adjacent side of.. the body, portion 5 ofrtheiclamp. n lVhen the jack is operated in. thejuproperimannerto extend the same, the clamp is slightly .canted so as to dig uintou'the: sides of the rail with a gripping engagement that .is increased 'in .proportion (302 1118 increase in pressure exerted against-the clamp by the jack. Thus,uas

the clampcannot .movelongitudinallyi of the rail,.the 1tie-12 willwbe .forced away Ffrom :the clamp OB-Shlfted' to its ,proper position.xeBy providing a socket 6 in each 'sideiof the body portion 5,vthe vclamp may be utilized upon either rail .of'a track, or

the jack may be utilized at either side of th clamp. In, removing the clamp, the same is merely tilted upwardly from the-po- -'sition .of 'Figurez2,'to'a position slightly further upwardly than "shown in Figure 3, whereupon the jaws are. so related to the-ball of the rail as to permit the clamps ready removal. a

From the-foregoing description, it is believed vthat the construction. and operation as well as the advantages of the present invention will be readily understood and appreciated by those skilled in the art.

Minor changes may be made without departing from the spirit and scope of the invention as claimed.

W'hat-I claim as new is:

1. Ina railway tie shifting device, a rail clamp includinga body member having rigid inner and outer jaws upon one end thereof and adapted to form an abutment :for a jack, the outer jaw being of angular form so as to extend across the top and extend downwardly along one side of the :ball of the rail, the downwardly extend- -ing-portion of said outer jaw being provided with anarcuate recess in the lower portion thereof adapted'to engage adjacent lower. corner 1 portions of the ball of the rail to provide a fulcrum about which the clamp may be bodily tilted in applying or removingzthe latter, said inner jaw dependof the rail, the downwardly extending portion of said outer-jaw being provided with an arcuate recess. in the lower portion thereof adapted to engage the adj acentr lower corner portion of the ball ofthe rail to provide a fulcrum about which the clamp may be bodily .tilted in applying or removing the latter, said inner. aw depending be1 and extending inwardly toward the-outer jaw and having the inner face ofithe lower portion .thereof of arcuate form .with its center of curvature at 'said fulcrum, said inwardly extending lower end portion ofthe inner jaw being arranged to engage the adjacent side of the web of a rail when the clamp is operatively applied to the latter for limiting downward tilting movement of the clamp at a point wherein the body.

portionis horizontally disposed at .one "side of the rail in proper position to act as an abutment-for a jack. 1' i .3.'In a railway tie'shifting device, a rail clamp including a body member, having rigid'inner and outer jaws upon one end thereof and adapted to form an abutment for a jackathe outer jaw being of angular form so as to'extend across the top and extend downwardly along one side of the ball of the rail, the downwardly extending portion of said outer jaw being provided with an arcuate recess in the lower portion thereof adapted to engage adjacent lower corner portions of the ball of the rail to provide a fulcrum about which the clamp may be bodily tilted in applying or removing the latter, said inner jaw depending below and extending inwardly'toward the outer jaw and having the inner face of the lower portion thereof of arcuate form' with its center of curvature at said fulcrum, the portion of the outer jaw below the arcuate recess thereof and the upper end of the lower portion of the inner jaw providing shoulders positioned beneath oppositesides of the ball of the rail when the clamp is completely applied to the latter, whereby direct upward displacement of the clamp from the rail'is prevented.

4. In a' railway tie shifting device, a rail clamp including a body member having rigid inner and outer jaws upon one end thereof and adapted to :form an abutment for a jack, the outer jaw being of angular form so as to extend across the top and extend downwardly along one side of-the ball of the rail, the downwardly extending portion of said outer jaw being provided with an arcuate recess in the lower portion thereof adapted to engage adjacent lower corner portions of the ball of the rail to provide a fulcrum about which the clamp may be bodily tilted in applying or removing the latter, said inner jaw depending below and of curvature at said fulcrum, said body portion having sockets in opposite sides thereof for seating reception of the head of the jack.
