I! .lnulllmulmzalllullll railed car wheel BENJAMIN J. BUELL, or READING,

oan-nnrnaonn CLAMP.

To all whom it may concern:

Be it known that I,

BENJAMIN J. BUELL,

a citizen of the United'States, and a res1- dent of Reading, in the county of Berks and State of Pennsylvania, have made and invented certain new and useful Improveof which the invention relates to holding devices or clamps commonly referred to as car replacer clamps, and which are designed-for use with car replacers or rerailers; the purpose of such clamps being to fasten the replacer to the rail and hold the same prop-' erly and securely in place during the replacin or'rerailing operation and while a de or wheels are being rethe rails of a railway track, the necessity of securing the the use of-spikes driven the same time providing.

placed upon thus avoidin replacer in p ace by into the ties and at means whereby and quickly put in place and clamped to the stated in which the clamp is rail, and as readily removed from the rail at the completion of the rerailing operation.

The objects of my invention are to provide a car replacer clamp for the purpose thereby secure the replacer proper in place relatively to a rail by means of a wedge movable transversely to a clamping bar extending transversely to and beneath the rail, and having a hook at one end adapted to engage the base of a car replacer, an abutment at the other end against which one edge of the wedge acts, and a movable block with which the other edge of said wedge en-- gages, to provide a clamp in which the clamping bar is bent so that the end thereof at which the wedge operates will be somewhat above the upper surface of theties upon which the rail rests; to provide a clamp in which the wedge referred to is permanently connected with or secured to the clamping bar; and to provide various particular features of advantage in and relating to clamps of the class above referred to.

With the above and other objects in view, my invention consists in the improved car replacer clamp illustrated in the accompanying drawing and hereinafter described and claimed, and in such variations and modifications thereof as will be' obvious to those lates.

Specification of Letters Patent.

the replacer may be easily .of my tightened to to be secured upon th PENNSYLVANIA.

Patented ea. 15, 1918.

Application filed June 4, 1918. Serial No. 238,075.

In the drawing accompa ying and forming a part of this specification and wherein the preferred embodiment of my invention is illustrated:

Figure 1 is a view showing my improved car replacer clamp in use and arranged to hold an ordinary form of car replacer to a rail;-

Fig. 2 is a view showing a section upon a vertical transversely extending plane indicated by the line 2-2, Fig. 1;

Fig. 3 1s a View showing the clamp and 1 in elevation, and

replacer shown in Fig.

to the left of said as seen from a position figure;

Flg.

a is a view showing a section taken upon a vertical longitudinally extending plane indicated by the line 4-4, Fig. 2';-

Fig. 5 is a view showing a which forms a part of my spective; and I Fig. 6 is a View showing the clamping bar device in perspective. 7 Referring to the drawing, the reference numeral 7designates ties of a railway track, and 8 one of the rails thereof; while the reference numeral 9 is applied to a car replacer designed to be clamped tothe rail 8 by my improved replacer clamp, resting upon and being supported by the ties and the inner wall thereof being usually cut .away so that it may extend slightly device, in peroverthe base of the rail, as shown in Fig. 2.

rail, as also shown in Fig. 2, to thereby movable block f space the replacer as a Whole slightly away from the rail and insure the proper location of the replacer relatively to the rail when clamped thereto.

My improved replacer ployed for securing any kind of a car replacer to a rail, and may be used either with inside or outside replacers. The replacer shown in the drawing, however, is an inside replacer, 'i. 0., a replacer designed e inside of a rail and to replace that one of the wheels of a car, locomotive, or other vehicle, which is between the two rails of the track. The replacer illustrated is a double-ended replacer,

and is capable of use in replacmg a vehicle clamp may be emwheel approaching it from either direction,

although my invention may obviously be placer -it soon reaches a height of the ridge 11 decreases gradually,

or, as otherwise stated, the bottom wall of the groove 12 rises more rapidly than the upper wall of the ridge. As the wheel travels up the'tread engaging ridge 11 of the repoint where the flange engages the bottom wall of the groove 12, after which the weight upon the wheel is transferred from the tread to the flange and is-thereafter supported by the flange.

The ridge and the bottom wall over the groove merge with each other at about the "point 13, and beyond this pointtoward the center thereof the upper surface of the replacer is so shaped as to provide 'a downwardly inclined surface sloping toward the head of the rail; the approximate form of this, surface at the central portion of thererailerwhere it attains its maximum inclination being shown at 14, Fig. 2. Before the wheel reaches the highest point of the" replacer, however, it will ordinarily have moved sidewise and slid down the inclined surface thereof at some place between the I point 13 and the middle portion of the replacer, and onto the rail, as shown in Fig. 2 As. above stated, however, ,my improved replacer clamp is capable of use with any form of replacer, and is not necessarily limited to use with replacers having the upwardly projecting tread engaging portion 11, the depressed flange groove 12, and the laterally inclined portion 14, present in the" replacer illustrated.

My improved replacer clamp comprises. a clamping bar shown by itself in Fig. 6,

and to which the reference numeral 15- is applied; the said bar being preferably of channel form and having depending sides 16 to thereby secure the requisite strength without unduly increasing the weight there of. These side flanges extend to the ends of the bar, as best shown in Fig. 6, and the said side flanges and the body of the bar are'formed into an upwardly extending hook 17 at the inner end of the bar, which hook is adapted to engage the inner edge of the base of the replacer 9, which is ordinarily provided with a flange as shown, to thereby force the lugs'10 of the replacer against the web of the rail and hold the replacer in place relative to the rail, as illustrated in Figs. 1 and 2 of the drawing.

memos The outer end of the clamping bar 15 is provided with an abutment 18 extending upward from the bar, which abutment is" provided with a groove 19 the outer wall 20 of which is inclined, as best shown in Fig.

1. The clamping bar 15 is bent slightly at plished, than would be the case if the clamping bar were traight.

The wedge 22 above referred: to is mov able transversely to the clamping bar in fastening the replacer to the rail and in releasing the replacer. Thiswedge isshown as provided with an inner edge 23 which extends substantially at right angles to the bar 15, and with an outer edge 24 which is inclined relatively 'to the clamping bar and cooperates with the inclined wall 20 of the abutment 18, as best shown in,Fig. 1. The

. outer inclined edge of the said wedge therefore moves along the groove 19 in securing the replacer to the rail or in releasing the replacer, and the innen edge 23 of said wedge also moves in a groove 25 provided in a block 26carried by and movable longitudinally of the clamping bar 15; and this block is preferably and is shown as provided with an overhanging ledge 27 adapted to fit over the base of the rail, as best shown in Fig. 2.

.The clamping bar 15 'is provided with a longitudinally extending slot 32, and the block 26 is provided with a depending neck 28 of such a size that it may rotate'within the slot 32 as well as move longitudinally thereof. The lower end of the neck 28 is. connected with a transversely extending head 29, the width of which "is not reater than the width of the slot 27, and t e free ends of which overlie the edges of the slot when the parts are assembled, as shown in Fig. 4. It therefore follows that when the block 26 is turned-so that the head 29 extends longitudinally of the slot 32, the head may enter the slot; after which the block as a whole may be turned through an angle of 90, to thereby bring the head 29 into the position shown in Figs. 2 and 4:, in which the head extends transversely to the slot and prevents the block from becoming disengaged from the bar by the action of the wedge.

The slot 32, neck 28, and head 29, obviously provide means for both guiding the firm engagement with the rail through the the clampingbar,

hook 17 at the inner end of the clamping I bar, as will be understood.

My improved replacer clamp is preferably provided with means for preventing the wedge from becoming separated from or, as otherwise expressed, for maintainmg the bar and wedge permanently associated with each other, so that the entire clamp forms a single unitary struc-' ture; The preferred form of means for thus holding/the wedge permanently connectedwith'the bar is shown as comprising a slot formed in the wedge and located'adj acent its inclined edge 2%, and a pin, bolt, or equivalentsecuringmember 31 which extends through a hole provided in thebar 15,

and through the slot 30'; from which it fol lows thatthe bar and wedgeare prevented from becoming separated from each other, and the inclined edge 24 of the wedgeis kept in a position adjacent the inclined wall 20 of the abutment 18, as the wedge moves transversely to the clamping bar during the clamping or releasing operations.

Having thus described and explained my invention, I claim and desire to secure by Letters Patent:
