DRAFT CONNECTION.
Application filed September This inventionrelatesto railway cars and has among its objects to provide improved means for the rotative engagement of a coupler yokewith a coupler and with a cushioning mechanism. l ln the usuali draft mecha nism of railway carsthe coupler yoke is suhjected to lateral 1bending stresses when the pull on-.the coupler` is vout of ,line `withthe longitudinal .axis ofthe yoke, which,l condi tion occurswhen the caris on a curve. But by providing rotative engagement between `the coupler and yoke and between the yoke and cushioningmechanism, these vbending stresses are eliminated under the above conditions; namely, when the car is on a Curve.
A further objectofthe invention is to provide a. draft connection for railway ears in `which the first co'stis greatly reduced, `as well as reducing the continued'operating costs. p f
lVith the foregoing `general objects in view, the invention consists of the formation, combination and arrangement of parts as set forth particularly in the appended claims,
. the various elements being coordinated to produce improvements generally in the art. The `present application is a continuation in part of my co-pending application, Serial No. 162.082,1iledApril18, 1921.
In the drawings, Fig. 1` is a plan showing a draft connection embodyingr my invention; Fi 2 is an elevation, partly-in section, thereof; Fig. 3 isa plan showing the method of placing the cushioning mechanism in position within the yoke beforethe -mechanismi is applied to the car.
Referring to these drawings the vdraft connection comprises a yoke with the upper `and lower arms 1 and 2,: respectivelwand-a vertically extending portion 3. y Boththe upper vand lower `arms are providedwifth vertically disposed slotsy 1, which have arc-k shaped bearings 5 at their forward ends. The coupler butt G on its top and hottomsurfaces is provided with `circular ,extensions 7,
each of which has laterallyextending lugs 8 arranged at right angles to the longitudinaly axis of the coupler. The cushioning mechanism 9 has an arc-shaped recess 41() inits e rear face which receives an arc-shaped face onthe vertically extending portion 3 of the yoke. Thus substantial pullingbearings'are v provided between the couplerand the yoke and hetweenthe yoke and cushioning mechaand at the same time thecoupler may 1, 1922. serial No. 585,772.
13 leading away from the arc-shapedl face 12 which serveto .guide the Coupler butt back,
during draft. o l ,v y l i.
The coupler and the yoke are connected hy swinging the couple'rpat right-angles rto the yoke and turning it on its side. The coupler butt, kwhen turned on its/SideQ-inay be `in-` serted betweenthfe upper and lower arms jof the yoke and them hy using the roundedporinto position afterit has been pulled awayv '11 is` also provided with tangential surfaces tion 14 `of the coupler `butt adjoining.. the
coupler may then he turned into longitudinal alignmenty with the yoke, thus locking .the coupler `to the yoke by .means of the lugs 8. The front follower 11 is placed in position withY its forward face12 against they rearface of the ,coupler butt.A y y .i l
To insert `the cushioning mechanismfinto position between the yoke4 arms the .'followei, block 11 isrotatedahout the couplerlnitt and the .cushioning mechanism placed with. its rear face against lthe vertically extending porh tionsjofthe yoke andpits frontface'gagainst the rear kface of the follower hlockfas shown in Fig. ,3.3 From this positionthe.,cushioning` mechanism and thefollowerblock may he forced into their ynormal position, placing the cushioningmechanism underr slight` compres-- sion and eausingthe follower blockto litV snugly against thecoupler butt. y After insertinggthe cushioningmeehanism the entire mechanism 'maybe elevated into ,position on the car. Beneath the yoke are the carrier irons 15, whichmay be o'fjany approved form, Vdetachably fastened4 to the car frame. These carrier irons not' only support the couplerv butt, yoke and cushioningmeehanism but also hold/the lug 8 on the topof the coupler buttr'near the topk cover plate 1G there by limiting* its vertical Vno ovemanta The'rear faces ot' the forward draft sill stops 17A are slightly tapered, asis the front face ofthe follower block whiclrcomes inn enL gagement with the stops. This will allow the front edges of the follower blocktoeenterfthe space clear of the rear edges ot' the stops and thereby permit the easy application Loit'it-li1ec mechanism to the car after it has been assembled. 1 f
