Tol aZZ whom z'ltmay` concern:

Be it known that we, BYnRsW. KABEL 4and Pliner R.- DiinNN1NG, citizens of the United States, residing at Baltimore city,- in the State of Maryland, have. invented cer"l tain new and useful Improvements in Draft Rigging; and we do hereby declarethe following to be a full, clear, and exact de' scription of the invention, such as Will enable others skilled in the art to which it appertains to make and use the saine.

rllhis invention relates to draft rigging for railway cars and the principal object, generally stated, isto provide a connection between the yoke and coupler, said connection including a vertical key and associated supporting means therefor.

Particularly stated, the invention consists of the provision of supplemental key'sup- 4portiiig and guiding members connected to the car frame and provided with rear walls or stops with which latter the rear edge oi" the lvertical coupler key is designed to cooperate in preventing rearward movement ot' the coupler beyond a predetermined posit-ion.

The invention has for a. further objecttheprovision of upper and lower supplemental coupler key supporting and guiding members, one of said members being relatively fixed to the Adraft sills and the other being detachably` connected thereto.-

A still'lurther. object of 'the invention is to provide a draft rigging .including in conibination, means for connecting the coupler and yoke so as to permit relative movement therebetween, said connection including a vertical key, means adapted to engage the yoke and prevent rearward movement there;

of Ytroni normal position, and means for guiding and supporting the said key.

` Other .objects will be obvious. as heieinafter set forth, reference being had to the accompanying drawings in which:

Figure l 'is a sectional plan view of the center sills and associated parts of a car under-frame showing a draft rigging einbodying the invention. i

Fioure @is a central longitudinal verti* cal sectional view of the.construction shown in Figure l, parts oi the mechanism being' Slots lO are fo ne View on' the line 3-3 of Figure 2,' and viewed in the direction of the arrows.

Figure 4 is a similar view on the line 4-4 of Figure 2, and viewed in the direc-- tion of the arrows.

'Figure 5 is a. sectional plan view on the line 5 5 nof Figure 2 with the coupler removed.

Figure 6 is a detail side elevation of a portion of the center sill, illustrating the respective key receiving members ot" the follower and lower vertical key supporting' member-riveted to said center sills.

Figure 7 is a detail central longitudinal sectional view through the lower vertical keyi supporting member.

eferring tothe drawings, in which siinilar reference characters designate correu spending parts in the several views, li have shown among other things the center or draft sills 1 of the car between which'is positioned the hackstop member or casting 2 connected by rivets 3 to said The bolster fland center plate 5 are of ordinary torni. Arranged between the coupler 6 and the backstop :member 2 is the cushioning means whichinclndes the key connected iol* lower 7 and interposed cushioning inschanism diiugrainniatically illustrated by the diagonal dot and dash lines in .Figure 2.

Cheek plates 8 are riveted to 'the vertical flanges or the center sills, said -cheek plates being provided with bosses 9 adapted to lit within openings 'foi red'. in. the center sills. in said bosses, throuvfh which slots passes the keyvllt connectinoft e :follower 7. @ther usual parte of the t rigging include tne end. sill 19; in the form ot' an angle oar an --over plate 13 which is preferably rive .d to the upper flanges 14 of the center sills l. A striking'casting 1.5 and associated carry iron .16 are provided, as shown in Figure 2.

Surrounding the cushioning mechanism is a vertically arranged yoke 17 having its for- 'wardly extending yoke arms increased in width, as at 18, to provide an increased hear-v ing area for the verticallyarranged coupler connecting key 19. Slots 20 are provided in each yoke arm, the forward portion of the side faces .of said slots being inclined or tapered and extending rearWa-rdl into relatively wide portionswith parallel opposed faces, :is shown in Figures 1 and 5, thereby providing lateral clearance t'or the pivotal movement of the coupler key, the key slot in the coupler 6 beingiadapted 'to closely embrace the seid key. i

The vertical coupler key 19 is of a; lengt-h which provides for its extending above and below the upper and lower tacesoi the yoke arms, seid key beingr ol e length greater than tlie. foiiiliiiied width i lche yoke and the coupler d. The projecting portions of the coupler key ure adapted to seat, respectively, in openings formed in the supplemental stop and guide members 21 and Q2.

'llie upper supplemental member 21 is in y the Vform et a bridge plate attachedi by rivets 2li to the top ot the upper flanges 1li of the center sills and is provided at its forward end and centrally thereof, with :i housing 24, Lhe. lower and trent walls or ends ot' which nre completely open to form u slot or groove 3 into which the upper projecting portion ot the coupler key 19 extends. 'lhe groove or slot 25 extends toiwvarflly ol the. plate and is of e. greater width than the coupler ke7 so es to permit oi the angling oi said key on pivotal movement; oi: tle coupler. rl`ho side Wells 'and rear wall of the housing, project below the plate or boil)VY port-ion ot the supple- 'iiientul member 2l, :is shown in Figure 2,

thereby forming` a relatively deep groove or slot in which ythe upper end of the eoupler key is zf juitled, and u rear stop with which the Coupler key engages when the cushioning mechanism becomes solid, 'that is, uttlie limit ofthe movement o the cushioning mechanism, the rear edge oi the coupler key engages the inner 'ta-ce of the i'eur wall in seid supplemental stop member 21.

The supplemental member 21 is strength-- cned by a series of webs or flanges, severel of' which act directly to supplement 'the strength ot the rear wall against which the rear edge of the couplerkey abuis. Leterally extendingI webs or flanges 26 are provided at eac-li end of the plate section end intermediate said` webs 'is another trans-` versely extending web 27 terminating in the rein` wall ofthe liousiiiT 24. A centrally located longitudinally arranged web 28 extends between the rear lateral web 96 sind .the reo r wall of seid housing', sind diagonally extending webs or tlangies 29 are airiing'ed between seid reiir Wall and the outer portions ofthe rem' lateral web or flange 25.

The lower supplementel stop member Q2 is' :attached to the center sills beneath Jche lower flanges tliereoiE by ineens of aldetachable. eouneetion which serves to permit the insertion and withdrawal of seid supplemental member, thereby allowing" the coupler key to be iemoved end another key. inserted. .ik housingr 30 having an open top Lis-ieee@ the coupler key 19 extends. The groove or 70 slot 31 extends forwardly of the supplemental member 22, and is of u. greener width than the coupler key so :is to' permit angling rof sind key on pivotal movement ot' thev coupler. The rear poition oli the groove or slot is relatively narrower and the sides thereof inwardly inclined, as indicated et 32, while the front portion of seid groove is of a width equelto the spacing of the side walls of the housing 30. The side Wells and 39'.

rear well of seid housing are :relatively high, thereby formingl e correspondingly" deep groove or slot in which the lower end of the coupler key is guided, and the rear wall with which the coupler 4key engages 85 when the cushionino mechanism becomes solid; that is, at theilimit of the' movement of the cushioningI mechanism the rear edge of the coupler key engages lthe\inner face of said rear well in the supplemental stopmember 22. The inner :tace of the hot-torn Wall of the housing 5G forms e bearing surface for the vertical coupler key. The lower supplemental member 22 is reinforced by means oit' depending Webs or flanges 33 95 extending; below the. bottom well of the housing SO und rearwardly the 'lull length ot' said member.

The respective reni Wells of the `upper and lower supplemental slopnieinbers 2l l0@ el elinement und this construction, togetli i `viti their depth, assures equal und nu muni. distribution of the strains, the rear edges of the coupler und 22 are in vez i key 19 simultaneously engaging said Walls 105 when the cushioning mechanism becomes solid. The supplemental members 2l and 9,9 act Los prevent spreading" olf the yoke firms and they also provide both supporting and guiding means for the coupler key without interfering with the aiieling 'thereot.

' The lower suivipleinentel member 22 'is detacliably connected to the center sills by ineens ot ai transversely disposed kej,f 341- 1115 arranged to ente' und closely it within a slot or opening 35 formed in the body poition o'lY the :supplemental member Q2, seid slot being of a shape corresoonding 'to said key. und rear wzill olE the 'housing P0 iii sind member l, is e, transversely disposed groove 'l adapted 'to receive the flange 37 ol' :i weer I'ilsite 35 interposed between the lower arm o'l the 'yoke and sind supple- 'liio weer plete out a of? the yoke uifrns mental ineinbein lh'irmed between the slotted 'portion M10 Leea'oee tioned between shoulder 39 formed by providing a depressed surface into which the.

Supporting hangers 41 are arranged ad.- jacent the bosses 40, each of said hangers being formed with a boss 42 having'a slot 43 therein corresponding to the shape of and adapted tov receive the transverse key '34.
