DRAFT APPLIANCE.

Specification of Letters Patent.

latented Dec. 4, 1906.

Application filed March 19, 1906-. Serial No. 306,900.

To all whom it N l/(Ly concern;

Be it known that we, THOMAS Enoon Cox and WILLIAM LENOX Cox, citizens of the United States, residing at Birmingham, in the county of Jefferson and State of Alabama, have invented certain new and useful Improvements in Draft Appliances, of which the following is a specification.

Our invention relates to draw-bars and draw-heads, and has for its object to provide a draw-bar embodying new and improved means for attachment to the frame of :a car and new and improved means for taking up the movement of the draw-bar under stress of draft or buffing.

A further object of the'in'vention is to provide a draw-bar embodying new and improved features of convenience, strength, safety, and efiiciency.

With these and other objects in view the invention comprises certain other novel constructions and arrangements of parts, as will be hereinafter fully described and claimed.

In the drawings, Figure 1 is an inverted plan view of the improved coupler. Fig. 2 is a top plan view of the coupler the carfloor removed. Fig. 3 is a longitudinal sectional view of the coupler, taken on line 3 3 of Figs.1and2.

Like characters of reference designate corresponding parts throughout the several views.

In its preferred embodiment the improved draw-bar forming the subject-matter of this application is mounted beneath. the usual and ordinary lls, as 10, of a car by securing transversely of the side sills the cross-bar 11, to the forward side of which is rigidly secured a guide member 12. Adjacent the endof the car to which the draw-head is applied are mounted brackets 13 and 13, spaced apart sufficiently to permit the draw-bar 14 to move longitudinally therebetween, the said draw-bar extending beyond the end of the car and provided with'a draw-head having shoulders 15 and '16 extending laterally therefrom. Upon the brackets 13 and 13 adjacent their rearward ends is secured a stirru 17, pro ortion'ed to embrace the drawar 14 an to support it between the said brackets.

"secured together at their forward ends by means of a rod 18 extending therethrough transversely of the car and provided be- The brackets 13 and 13 are tween the said brackets with a sleeve or roller 19, upon which the draw-bar rests and is movable.

The draw-bar 14 at the point where it extends through the guide 12 is reduced in size and is preferably formed circular in cross' section, as at 20, defining a shoulder 21, between which and the guide 12 is disposed a coil-spring 22. Adj acent the ends of the bar 20 and within the guide 12 is" disposed a washer 23 in any approved manner, as by a pin 24, and'betweenthe said'washer and the guide 12 is disposed a spring 25.

Upon the upper surface of the draw-bar 14 is formed or secured a lug or bracket 26, rigid with the bar, having therein mounted a bolt 27, provided at its forward end with a rigidly secured to the beam of; the car, and betweenthe said plate'29 and the lug 26 is disposed a spring 30, embracing the bolt 27.,

.hlch is held from displacement within thelug 26 in any approved manner, as by a nut 31. i

. Between the guide 12 and the spring 22 is arranged a late 32, extending laterally upon each side 0 and embracing the portion 20 of the draw-bar and to the ends of which are se res ectively,"thr0ugh the brackets 13 and 13 an provided at their forward ends, respec tively', with heads and 36 normally in contact with the shoulders 15 and 16 and with s ring 37 and 38 between the said heads and t eir associated brackets. The bars 33 and 34 are longitudinally movablethrou h the plate 32 and the forward movements't ereof are limited by means of nuts 39 and 40 upon What we claim is' 1. In a draft ap liance, brackets; mounted upon'the sills 0i tl fe car and spaced a art, a crossiece extendin transversely of t e car, a gui e carried rigi y upon the cross-piece, a draw-bar disposed between the brackets and extending through and to move longitudinally in the guide and provided with a shoulder forwardly of the guide and with a collar rearwardly of the ide; rings interosed between the sho der'an guide and etween disposed between the brackets and positioned to en port the bar.

j 2. In; a aft appliance, spaced brackets head 28, disposed to contact with a plate 29,

collar and guide, and a roller.

cured bars 33 and 34, extending forwardly,

the said bars and rearward of the said plate.

secured tothe beam of the car, a cross-piece rigidly secured to the beam of the car rearwardly of the brackets, a guide rigidly secured to the cross-piece between the said crosspiece and brackets, a draw-bar disposed between the brackcts and extending through the guide and provided with a shoulder, a buffer-spring"disposed between the guide and the shoulder, a collar secured upon the rearward end-of the draw-bar, a draw-spring disposed between the collar and the guide, a bracket rigidly upstanding from the draw bar and spaced from the sill of the car, and a drawspring disposed between the bracket and the sill.

3. Ina draft appliance, a bracket secured to the sill of the car and spaced. apart, a cross-pieceseoured to the sill of the car and extending transversely thereof, a guide ligidly secured to and extending forwardly of the chesspiece and between the said cross: piece and the brackets, a draw-bar disposed between the brackets and extending through the guide and provided with a shoulder, a roller disposed between the brackets and arranged to support the draw-bar, a bufl'erspring interposed between the shoulder of the draw-bar and the guide, a collar secured upon the rearward end of the draw-bar, a

draw-spring interposed between the collar in from the draw-bar and spaced from the sil of the car, a rod mounted to reciprocate in the said bracket and provided with a buffer-head upon its forward end positioned to contact with the sill, and a spring interosed between the buffer-head and the racket. v

In testimony whereof we affix our signatures in presence of two witnesses.
