zThis invention relates to railway'cars andl has particular referenceto articulated cars in.

adjacent endfy portions oftwo car bodies arel supported-by. afcenterplatecarried by a truck bolster,ythe axis of horizontal swiveling being defined by. .af king bolt or. pivot pin secured to the bOlster'and-'deining the support for al foot plate which spans the adjacent fend portions fof therca-r bodies.. l

IOther obje'ctsand,v advantages'of this in! vention will be apparent froniithe following' description taken with the accompanying drawings in-which Figure -lfis atop plan'view of the adjacent end portions OfftWo-carf bodies,ia'part of the figure being taken o'n'the lline 1:1', Fig. 2. Y Fig. 2 is asetional view through the adjacent end portions oftlie cari bodies, the view showing the articulatedjoint` and'also showing, diagrannnatically, a portion 'of a car-V truck.V 1 y Fig; 3"is a top plan view of the center plate, and

Fig. Irisa side elevation shown in Fig: 3.

' Referring` nowmore yparticularly to the drawings in which'similar characters of ref'- erence designate similar parts inltheseveral views, inasmuch as fthe inventionfmay'be applied to almost any `desired'form of car body, the construction of tliebody above the underframeis not illustrated. The bodies are providedwith underfraines which include spaced center sills 2,'ch'annel'ishaped in the instance shown, over Whichendjloor sheets alare an ranged,- andibet'ween. the center sills body connection castings A and B,-respectively,are.

ot the centrer plate arranged andare secured to said center sills by suitable fasteners suchas rivets Llor the likey The castings A. andfB are substantially hollow and reinforcedfby suitable ribs 5 and cooperate witha center plate()` carried bybolsterD 7forming part of? alcar truck, of

1931. Serial No. 544,434.

which latter a portion E is illustratedy diaf grainmatically.

As more clearly shownin Fig.v 2, thefbolster D is of box formation and intermediate. its ends is provided withan apertured guider lug 6 concentrically arranged with respect to an annular vertical rib 8, saidlug (iand'rib 8 defining therebetween an annular recess 9l which receives the center plate-C, the latter supporting the adjacent end portions of the car bodies. f

The center plate C is substantially circular insliape and comprisesa hollow casting/having an annular supporting ange l0 forinedf with and depending from' its lowerv 'Wall' A12; ther flange'lO fittingA the before mentioned recess -9 and positioning they center plate, as will befappare'nt. The upper wall 14 ofthe casting C is provided with an annular recess' 16 into which arcuate bearings lS--forrnedl with the lower Walls 20 of the castings A and B eXtendwhereby the adjacent end'portions of the car bodiesrare supported for horizont tall swiveling in the centerl plate.

The end portions of castings A and Bare formed into aperturedprojectionsV22 and24, respectively, which lap eachother inspacedl relation and which are alined, as more clearly, shown inFigs. l and 2, to receive a king bolt or pivot' pink 26 which yextends therethrough and through the centerplate'C (the upper and lower walls thereof being centrally aperitured) ,'and'through the bolster D; the pivoty pin 26 beingr secured to the bolster in` any suitable manner. In theinstance shown,.thev lower end of the pin 26 carries a nut28 Awhich is threadedly engaged in the lower or bottomwall 30 of the bolster, andl is provided for they purpose of securing the pin `26 Vto the bolster.y

In articulated car construction it is'necessary to provide a means for permitting ltransfer of passengers from onecar body tol the other and linthe car of the present invention a foot rplate 34 isprovidedwhich spans-'the space between the adjacent car bodies and'is mounted on and secured to the upper end of4 the pin 26 in any suitable manner, as shown at 36; the foot plate 34 overlapping'the end cover plates 3, as clearly shown in Fig.' 2S

In use, itlwilLbegapparent thatthe respective car bodies may swivel horizontally relative to each other due to the supporting thereof by the center plate C and the body connection castings A and B. Excessive rela tive vertical shifting of the car bodies is prevented by reason of the fixed connection of the pin 26 in the bolster D, and the foot plate supporting bracket 38 secured to the foot plate 84. It Will be apparent that excessive sidewise shifting of the respective car bodies is prevented by reason of the arcuate formation of the bearing members 18 and their engagement with the center plate C. To disassemble the construction shown, the nut 28 is removed whereupon the foot plate 34 and pin 26 may be removed by lifting the same vertically out of connection with

theF projections

22 and 24 and the center plate and then either or both oi the car bodies may be removed from their engagement with the center plate C.

The drawings herein illustrate one embodiment of the invention, but it is to be understood they are for illustrative purposes onlyI and various changes in the form and proportions of the construction shown may be made within the scope of the appended claims Without departing from the spirit of the invention.
