Figure 2 isa horizontal, longitudinal sectional view of one end of the Vunderframe structure illustrated in Figure 1- and corresponding substantially to the lino 2-2 of Figure 3L Figure 3 is a longitudinal, vertical sectional view, corresponding substantially` to the rline 3-3 yof Figure 1. And Figures 4 and 5 are vertical, transverse sectional views, corresponding Vsubstantially to the lines 4 4 and 5-5 of Figure 3, these views being partly broken away.

In said drawings, 10-10 indicate the front and rearbody holsters of the Vcar underframe The car is providedwith couplers at each end thereof,

the same being'partly broken away andthe Shanks thereof being designated by 12-12, each shank having the usual head 13 at the outer end thereof. Y y

In carrying out my invention, I provide body bolsters of special design, as most clearly illustrated in Figures 2, 3 and 5. Each body'bolster comprises atop plate 14 extending entirely across the carv and secured'to the Y f usual side sills,V not shown; bottom` plates f '15e-15 extending inwardly from the side sills o and secured thereto in the usual manner; dia- 30 phr'agm plates 16-16y secured to the side plates andtop plate; and a central casting 17. Thev casting 17'` has lateral-ly extending hollow sections 18-18 on opposite Vsides thereof defined by inner vertical wall pory too plate 14',

'tions 19-19, spaced sidewall portions 20-20 and top andl bottom wall portions 21-21. The hollow sections 18 Vare preferably .reinforced 'by a'central vvertical web 22 formed integral with the top and bottom walls and theinner end wall 19. As most clearly shown in Figures `Zand 5, the walls 19 are spaced apart fora purpose hereinafter pointed out. VThe portions 18V of the casting are connected byY a Yrelativelyfthick bottomA web 23 formed integral with' the Vbottom wall portions 21.Y

The topwall -21 of each member 18k is downwardlyoffset, vas indicated at 24, thereby providing an opening'or guide-waybetween the same and the top plate 14 of the bolster member.. vAt the-bottom end, each wall 19 is con'- l ure 5.; f The web `1nember23 is provided'with-upstanding "spaced transverse ribs or walls as most clearlysh'own in Fig- 26-26, there preferably being four such ribs or walls. Two of the ribs 26 'are located at thefront and rear edges of the web 17 and the remaining two are ydisposed closely adjacent each other approximately atthe center of saidrweb. The-web 23o-isv provided with the usual center pin receiving opening 27 which accommodates the pin that connects thebody and truck holsters. As shown in Figures 2 and 5, the ribs 26 areconnected by web members which define, together with the central portions of said ribs, a tubular upper section, the-opening of whichris a continuation of the .centerpin receiving opening of the web 23.

The ribs 26 have their opposite ends spaced from the walls 19, thereby providing an opening at eachside for a purpose hereinafter pointed out.

The end sill members 11 at the oppositek f ends ofthe car are also of special design, each being provided with an opening 28 adapted to accommodate the coupler shank and associated parts of the draft rigging. The opening is defined by a top wall 29, rside walls 30e-30 and abotto-in wall 31 in the fo'rin of a detachable plate. The top wall 29 forms in effect a continuationof the top member of the end sill., The side wal-ls 30 are relatively thick and are Vrecessed ontli'e innersides at the bot-Y tom thereof. as indicated at 32-32, tovprovide pockets or seats adapted to accommodate the opposite sides of the bottom plate 31 so that the bottom face of said plate will be flush,

with the bottom member of the end sill.

As m'ost clearly shownin Figure 4, the plate 31 is relatively heavy and is reinforcedV `by a plurality of longitudinally extending bottom webs or ribs 33-33. The plate yis preferably secured to the end sill by means of 'vertically disposed bolts 3434 extending through thesill." Theside walls 30 are proasl vided with vertically disposed, opposed, relay Y tively thick ribs35-35 on the inner sides thereof, the ribs 35 presenting fixedl stop l shoulders 36 and 37 at th-e front and rear'sides thereof. The end sill is also provided with rearwardly extended, spaced, vertical wall portions 353-38.r the outer sides of which are Y in alignment with theV side walls 30. The

inner surfaces of the walls 38 vare outwardly offsetwith respect to the side walls, thereby presenting transverse shoulders 39-,39 which corresponding' end sill. The bottom plate is of such a length that the rear edge thereofY is in substantial alignment with the rear ends of the walls 38, as most clearly indicated in Figures 2 and 3. y

A pair* of channel shaped spaced sills 4 0-40 are arranged lengthwise yof the car,

Vare in alignment with the rear face-of the A the oppositeends of the same being support- Y ed byl the plates 31'Vand are guidedbetween the walls 38-38 of the end sills.

The sills 1 4G pass throughthebody'vbolsters ofthe car.VK

and the vertical ywebs thereofare guided be-K- Y shell type:

tweenthe walls Y19 andthe outer edges of the ribs 26 of the. holsters, and the top and bottom'flanges of4 each sill are guided in the openings defined by the topl plate 14, ythe'oifset wall portion 24 and bythe bottom wall 21 and the offset wall portion 25 at the corn responding side of'each body bolster. Y The two sills 40 are preferably connected by cover plates 41-41 secured to the top flanges of the sills,` tie plates 141-141 and saddle plates42-442vsecured `to ,the bottom flanges.I The sills are spaced apart the proper distance to receive a shock absorbing mechanism therebetween, whichmay'be either of the spring or friotion'typ-e, themechanism shownV in thedrawings being ofthe friction sills40 terminate Vshort of the shoulders'BQ of the fronti and rear Yend sills and are 5 nor? ally centered between said shoulders oftlief two end sills. In order to strengthenv the ends of the sills 40, reinforcing castings 43+43 are employed, the castings having vertically disposed walls fitting the outer faces of the vertical webs ofthe sills .40, transverse end* v walls terminating flushwith the ends of the theinner surfaces ofthe top and bottomv sills and Jtop and bottom flanges engaging vflanges of the sills. The reinforcing-cast.- rings 43 are preferably secured tothe sills by riveting, as shown inthe drawings. It will be understood'thatthe construction of the sills 40 is the same at both ends ofthe car. -'and that both` ends of the same are reinforced by cast-"-A ings 43. 1 Y

A stop sleeve 44 is emdployed at eachend of tliecar, the same being isposed in the opening 28 of the corresponding end sill. :Each sleeve 44 is preferablyof substantially .rec-

tangular cross section having spaced verticalv f side wallsrand horizontally disposed, spaced top and bottom walls. VAt the forward end,

the side walls ofA each sleevevare. provided with opposed laterally projecting lugsV or vertical ribs( 45-45 which cooperatefwith Vthe. shoulders 36 to' limit the inward movement of the sleeve.

vBetween' the ends, the side walls are pro-f videdwith an additional .pair *of laterally extendinglugs or ribs46-46 vwhich co0perate with the-stop shoulders 37 to limit the outward movement of the sleeve. yEach sleeve is also provided with coupler key `guide slots 47-47 in the opposed 'side walls thereof. The side walls of the-sleeves 44 are spaced apart such a distance that the sleeves will .work freelybetween the ribs 35 of the end sills, and the lugs 45- and 46 are so designed that they clear the sidewalls ofthe openings 'in said end sills. The .front end of each sleeve- 44 is normally spaced such a distance from thecorresponding coupler heady as to;`perm1t relative movement ofzthe parts to an extent at yleast as great as the 'compression` stroke of fone of the shock absorbing mechanisms The front and rear ends of the,v

employed. The sleeve 44 at each end of .the

car'accominodates'` the Vcorresponding coupler shank' andthe rear endportion':thereof-fum tions as the frontl vstop meniberffor'thegshock absorbing mechanism at'that'end'of theear. f Each coupler shank has? a yoke memberv y 60 connected vthereto byja Vkey i48 extending through an openingin the coupler shank` and aligned:guidejslotsu49449 in the side-arms ofthe yoke. The yoke 60 is ,ofa well known type andfthes'hock `absorbing means, aswell therewithin. `The shock absorbing mvefans'is ofthe well knownfrictionV shelltype and includesl a -frictionshe'll 51,*fa' pair of' friction y shoes 52-452, a wedge( block 53' cooperating asa frontmain'follower"50, is supported with the shoes, the shell containing: the usual .Y

mechanism between the inner' end of the Vyoke s and the main followeritO, the latterfbeing held inlixed position with respect to the carY by engagementjwith the -inner end of the sleeve 44 at that 'end of the car, the'latter being held against-outward movement bythe lugsf46 thereofengaging the stop shoulders 37 of the end sills Y ACompression of the friction shock absorbing mechanism will belimitedby engagement/of the' friction shell with Y the main follower 50. In this connection, it is pointed out that theoutward movement of the coupler head with respect to the end of the car and the corresponding sleeve 44 will be'equal to `the'comr'iression stroke of the friction shock yabsorbing mechanism.

V.When a 'bufling actionr is appliedVV to the coupler at one end of the car, the samewill be forced inwardly, thereby forcingthe corresponding outer follower inwardly also and compressing the frictionshock absorbing mechanism between the outerfollower and -thel stop lugs 54of the sills 40 at the 'same-end ofthecar. Inasmuch as thesills 4() are movable,vthesame will be moved longitudinally ofthe car during the described action, and

Vthe friction shock absorbing mechanism at the other end of thecar rwill be compressed betweenl the stop lugs 54 at that endof the Vcar and the corresponding vfront* or main follower V50 which is held against movement by engagement with the sleeve 44, the 'lugs 46 of which are held against y movement-by engagement with-the shoulders v37' of the corresponding, end sill.V r l f As will be evident, a'longer stroke is obtained. in a buliing action than is had in draft, because the shock absorbing mechanisms at both ends of the car are compressed'during a lbmi-ing stroke. 'Duringthe inwardmovement kof the coupler hereinbefore referred to, the corresponding coupler key will engage the inner end walls of the slots 47 of the corresponding sleeve, thereby forcing the sleeve inwardly. also, this `movement beingpermitted lby the clearancerprovided between Y the lugs 45 of said sleeve andk the shoulders vfill. y

Ling either held stationary and theV rfurther expansion of the shock absorbing mechanisms will force 36 of the corresponding end sill. The rela` tive movement betweenthe coupler and the sleeve 44 is thus 'substantiallythe same durawdraft or'buiii'ng action ofthe mechanism.

In release, afterthe railway'draft rigging lhas beensubjected to a builting action, the expansion of the shock absorbing mechanisms at'the oppositeend-s of the car will'force the Y rfollowers 50 outwardly,'carryingthe couplers outwardly therewith during the first part of the rel-easing action and then engaging the sleevesA 44 and forcing the s ame outwardly until movement thereof is limited by engagef ment ofV the lugs46 with the shoulders of the en'dsills, whereupon'the followers will be the draft gears during the inward movement kthe sills-40 to their centeredposition between the end sills of the car, the centeringrforce being transmitted thereto through the inner stop lugs 54whichjy cooperate with the shock Y absorbing mechanisms.V y

n The spacing betweenthe ends of the sills 40 Aand the shoulders 39 of the end sill at each end of the caris preferably such as to equal the compression strokel of the lcorresponding shock absorbing mechanism, sorthat movement ofthe sills 40A will bear'rested at `the same time that compression of the corresponding shock absorbing mechanism is limited by engagement of theshelll with Y the outer follower 50, thereby distributing ofthe coupler inbuii and the outward move. ment of thesame during'releaseafter a buffingaction. Y This 1s exceedingly important 1n railwa practice, because an excessive extension o the coupler 'head with respect'to the end of the car and the striking casting thereof would endangei'the trainman because the extension of the'coupler head-wouldbeV 'so great as to permit the trainmans-foot' to get caught and injured when the coupler is movedY inwardly during a' builing action. Y y i While Ihave herein shown and described' sor what I consider thevpreferred manner of carrying out vmy invention, the same ismerely illustrative-andI contemplate all changes and modifications which come within Ythe Y scope-of the claimsfappended hereto. e
