l Application filed January 20, 19010. Serial No. 2,134. (No model.)

V`To n/Z when@ it 777,027/ concern:

Be it known that I, CLEMENT F. STREET, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Draft-Rigging for Cars, of which the following is a full, clear, and eX- act description,- reference being had to the accompanying drawings, forming part of this specification.

My invent-ion relates to that class of draftrigging employing a tail-strap united to the tailpiece of the draw-bar and which communicates the pulling and buihng strains to the spring mechanism contained within said tailstrap or partially exterior thereto and which is supported .on followers and stop-bars, thelatter of which are carried by metallic sills which form a part of the framework of the car; and it has for its objectthe provision of an improved draft-rigging of this character of simple, inexpensive, and reliable construction, so that it maybe readily assembled and put together or taken apart and will afford a perfect resiliency to both pulling and buiing strains.

The novelty of my invention will be hereinafter more fully set forth, and specilically pointed out inthe claims. l In the accompanying drawings, Figure lis a central longitudinal'view, partially in elevation and partially in section, of a draftrigging embodying myinvention with springs arranged in tandem.4 Fig. 2 is a horizontal partial sectional view of the same on the dotted lineX-Xof Fig. 1.@ Fig. 3 is a transverse section on the dotted line Y Y of Fig. l looking to the left. Fig. t is a sectional detail plan view of opposite portions of the metal beams with an interposed stop-bar between them, showing one manner of uniting the parts. Fig. 5 is a broken perspective view showing the application of 'my invention to twin-spring mechanism located side by s ide. Fig. 6 is a horizontal sectional View through the center of Fig. 5, the springs being shown in full. Fig. 7 is a longitudinal broken perspective view of the metal beams with the stay-lugs, draw-barV carrier-iron, and tailstrap guide attached thereto and stop-bars in position, the draw-bar mechanism being removed. Fig. Sis a sectional detailshowing the manner of introducing one of the staylugs for' supporting the stop-banin its position in the sill. Figs. 9 and l0 represent in perspective two forms of stay-lu`gs detached from the beams. Fig. llis a perspective view of one of the followers detached from the draft-rigging mechanism. Fig. 12 is a broken perspective view of one of the stop-bars with key inserted in the end thereof. Fig. 13 is a broken perspective view showing a modificationof the stop-bar and stay-lug.

The same reference letters and numerals are used to indicate identical parts in all the figures.

Referring now to Figs. 1, 2, and 3 of the said drawings, I will describe the application of my invention where tandem springs are employed.

A represents the longitudinal parallel sills under the floor B of the car.

C is the end sillor interior end cross-beam, and D the exterior dead-wood or bu ffing block. Flanged metal beams E are'secured to the under side of the sillsA by means of bolts a, which Vpass through said sills and through the perforations b in the flanges c of said beams, which beams may extend the entire length of the sills A, or they may extend only such portion thereof as may be necessary to perform the function above ascribed to them. These beams may be rolled, pressed, or cast into shape, the webs d of which carry the draftrigging mechanism between them in the manner hereinafter described. t The said draftrigging mechanism may consist of the usual or anysuitabl'e draw-bar F, whose forward end ha'sa coupler of any desired construction attached to it and whose `tailpiece is bolted by bolts e to a strap-frame or tail-strap G, occupying a vertical posit-ion between the said beams, as seen in Figs. 1 and 3.

Within the tail-strap are two followers H, their forms being more clearly indicated in Fig. 11. These followers consist of followerplate f, provided with studs g on the face side thereof, and with loop extensions h, forming openings i at the back of said plates. Stopbars I pass through the said openings t, the horizontal dimension of which is sufficient to provide for the necessary forward-and-backward movement of the followers, which op- IOO crate within the tail-strap and which are enfgaged by one or more sets of coiled springs .l

K, one within the other, the inner of said springs being retained in position between the follower-plates by-means of the studs g and the endsof both of said springs bearing against the said plates, the two springs being reversely coiled, as shown. are arranged between the beams E, near the forward and rear ends of the tail-strap G. These bars are preferably formed hollow, of rectangular shape, with one or more horizontal division-webs j tostrengthen them against the strains of pulling and buffing, and they pass through stay-lugs L, secured to the webs d of said beams, being held in place therein by means of heads or flanges 7c at one end and keys lkwhich pass through perforations dicated in the drawings. may be of either of the forms shown in Figs.

m, either to the interior or exterior of the webs d, as Seen in Figs. 2 and 4, in which former case the lug shown in Fig. 9 is employed, the `flange 'n and lip o being on the same side of the web. The lugs employed in Fig. 4 are of the type shown in Fig.v l0 and in which the flange n andlip p are on opposite sides of the web. Both of said types of lugs (shown in Figs. 9 and l0) are provided with projecting members q, which are adapted to be inserted into corresponding openings. formed in the webs d of the beams E to give additional strength and partially relieve the strain from the fastening bolts or rivets. These projections are perforated at r for the passage of the stop-bars, and the lugs are also provided with outwardly-extending brackets s, which afford larger bearing-surfaces for the stop-bars and strengthening-webs 6, and they are preferably formed in a single piece. When the form of lug shown in Fig. l0 is employed, the manner ot' insertion into the openings in the 'webs is indicated in Fig. 8, and the lug is then turned so that its flange n and lip p embrace both sides of the web, when the said flangeis secured to the web by bolts or rivets, as hereinbefore described. I consider this form of lug superior to that shown in Fig. 9 for the reason that the flange rnl and lip p engaging, as they do,- opposite -sides of the web the stop-bar must be withdrawn from the lug before it can be removed from its gpening in the web, which is an important feature, as the parts are not liable to become displaced incase of breakage or removal of the bolts or rivets by which the fastening of the lug to the web is accomplished.

In Fig. 13 of the drawings I have shown a modification of the stop-bar and stay-lug hereinbefore described and in which there is no perfora-tion either in the metal beam or the lug, the latter being made with a plate portion t, by which it is secured to the insideof the web of the beam and from which plate por-V The stop-bars I pocket w, adapted to receive heads or anges :I: at each end of the stop-bar M, which rests on the bottom part y of the lug and which is inserted in the said pocket from the top side of the lug. While I have shown only a portion of one of the beams, with one lug attached 'thereto and one end of one of the stop-bars in position in the lug, it will readily be understood that the construction at the opposite side is the same and that all the lugs and stop-bars may he similarly constructed.

v- The outer ends of the followers bear the one against the rear end of the tail-strap and the other against the rear end ofthe draw-bar,

Vwhile the back sides of the follower-plates bear against the stop-bars, as clearly indicated in Figs. l and 2. Secured to the rear end of the tail-strap by rivet or bolt a is a Ain* the bars at the opposite end, as clearly inz The stay-lugs L rearwardly-projecting follower N, and just in rear of this1 follower isa spring-bearing 3 plate O, having a loop 1 strung upon a third 9 and lO and may be riveted or bolted, as at strains are transmitted through the tail-strap and rear follower H to the springsJ K,which are compressed as the draw-bar is pulled forward against the follower H, which is held from forward movement by its stop-bar, and

the rear springs P Q, are not affected, as the ICO follower N is simply drawn forward by the tail-strap; but in buling strains, where the draw-bar is pushed. backward, the intermediate and rear stop -bars arrest theiry followers, while under the backward movement of the tail-strap the forward follower H and the follower N compress both sets of springs, as will be readily understood.

Where it is desired to have two sets of springs to receive both the pulling; and buffing strains, they may be arranged side by side,

4as seen in Figs. 5 and 6, where the metal sills .in the manner heretofore described with reference to the construction of Figs. l and. 2. The loops of the two followers H surround the stop-bars, as in-the former construction,- and they each have two studs g on theirv adjacent faces to receive and retain the two pairs of coiled springs, which occupy positions side by side and bear against the face sides of the followers. When at rest, the followers are pressed away from each other, 'so as to bear against the stop-bars, as clearly indicated'in Figs. 5 and 6, and when a pulling strain is exerted on the draw-bar the forward follower remains stationary in contact with its stopbar, while the rear follower is carried forward by the tail-strap and compresses the springs, as beforev stated. In the backward movement of the tail-strap under bufting IIO strains the rear follower remains stationary, arrested by its stop-bar, and the forward follower is pressed backward away from its stopbar and puts the springs under compression, as will be readily understood.

One of the important features of my presentinvention, whether tandem or side-byside springs are used, consists in the employment of the metal sills with vertical webs and dan ges or other means for securing the same to the sills A or directly to the floor or other part of the car and in the combination with these metal sills, which support the draft-rigging, of stay-lugs so secured to the sills as to afford bearings for the stop-bars.

,'Iheforward end. of the draw-bar mechanism is rsupported by means of a transverse carrier-iron R, provided withupwardly-pro jectng studshwhich act as guides for retaining the' draw-bar in line, and at the rear end of the drawbar mechanism there is a transversely-arranged strap S, secured at.`

each end to the-lower flanges of the beams E and having guide-lugs for retaining the said rear end in line, thefffsaid rear end being supported on the stopbars, which in turn are supported by the metal beams E.

While I have shown thestop-bars as hollow and preferably rectangular in cross-section, they may be solid, if desired, and of any shape in cross-section that suits the idea of the constructor, and instead of thev yend fastenings for the stop-bars which I have illustrated and described they maybe fastened at their ends by any other means, such as nuts screwed on threaded ends of the stopbars.

Other modifications in structural details may be made without departing from the spirit of my invention.
