To all 'whom it may cof/wem.'

Beit known that I,- ALFRED K. PEHRsoN, a subject of the King of Sweden, residing in Bellevue, in the county of Allegheny 'and State of Pennsylvania, have invented certain new and useful Improvements in Articulated Cars, of which the following is a specification. l n

This invention relates to articulated cars each of which comprises a plurality of car bodies andhas for an object the provision of a vestibule member between the adjacent ends of two of the bodies which is operabley jacent ends of two adjacent bodies of an ar-v ticulated car, will cooperate with said bodies ,in such a manner that the transverse center line ofthe vestibule member will bisect anyr angle formed by the longitudinal `center lines of the adjacent bodies. 1-

Anotherobject of the invention is to provide the adjacent ends of the adjacent bodies of an articulated car with means for driving 'or adjusting the vestibule member, arranged between said ends, to its proper position relative to said bodies, so that the passagef waythroughthe ear' will be unobstructed at all times. a

A furthery object of the invention is the provision of means whereby the vestibule member, between the adjacentends of two adjacent bodies of an articulated car, is supported by one of the bodies.

Referring to the drawings in which like' reference characters refer to like parts, Fig. 1 is a sectional plan view of the adjacent ends of two adjacent car bodies and vestibule member-of an articulated car embody-l ing the invention; Fig. 2 is an `ilarged 4cross sectional view taken-)on the line 2-2 of Fig. l; Fig. 3-is an enlarged longitudinal ,sectional view taken on the l, i 3--3 of Fig. 1; Fig. 4 is an enlarged sectional view taken on the line 444 of Fig. 1; Fig. 5 is a diagrammatic plan view ot a portion of the car showing the positions of the adjacent end Vportions of two adjacent bodies and the vestibule member and mechanism when these bodies are on a portion of straight track;

Fig. 6 is a like Viewl showing one of the bodies on straight portion of the track and the other on a curved portion of the track 'and Fig. 7 is a like View showing both of the bodies on a curved portion ofthe track.

.Referring now in detail to the drawings, the reference'jcharacter l indicates an articulated .car'which comprises a plurality' of bodies 2, thev adjacent ends of which are pivotally supported lupon a truck (not shown)` of any suitable construction. In the present embodimentl of the invention the' truck bolster 4 is provided with a truck center bearing member 45 in which the body center bearingf members 6 of the adjacent ends of the underframes of two adjacent bodies are adapted to extend and cooperate with to form a bearing for the bodies and for maintaining said bodies in their proper spacedrelation against longitudinal movement Jin one direction, there being a spherical member".7 mounted inthe underframes above the center bearin which prevents relative moveniient of the bodies in the opposite direction and also prevents one underframe from moving vertically relative to the other.l

The foregoing construction has been descrlbed in detail in an application for U. S.

fment.

Between the adjacent ends of two bodies a vestibule member 8 is provided which comprises a bottom 9, sides 1() and a top or roof portionfnot shown). f' The construction of this member 8, its application to the adjacent ends of two bodies as well as the weatherproofing means between the member vandthe bodies have been fully described in a -pending application for U. S. Letters Patent filed September 1, 1925, in my name and Karl O. Winell, jointly, for articulated Letters Patent filed February 14, 1925 in 602 j Cif-he vestlb car, and` serially numbered 53793. The bottom 9 ofi this member has secured to its underside a center bearing member/12 which seats in' and cooperates with a center bearing member 13. secured to or formed integral with the -end portion of one of the underframes. 7 i

At each'side of the longitudinal center line oi the car, a pair of links 14 are provided the adjacent endsfof which are pivotally connected to a projection 15 formed on a slide member` 16. These links ,when so connected extend between the adjacent ends of adjacent cars and their outer ends are 15 pivotally connected with the underframes through the medium of bolts 17 or any other suitable means Secured to the underside of the bottom 9 of the vestibule member 8 there are mem- 20 bers18 each of which islocated at the transverse centerline of the vestibule member at one side of the longitudinal center line ot the car and vestibule member. Each member is provided with 4a groove or way 19 which is preferably of T shape and is adapted to receive the upper portion or fhead 20 of the member 16 in such a manner that the member 16 isr freely slidable inthe slot 19. It will here be noted that as lthe 39 adjacent bodies of the car assume an angle to each other, the links 14, due to their connections with the bodies and their slidin connection with the vestibule member, wil cause the vestibule member to rotate to such' an extent that the transverse centerline of* the vestibule member will bisect any angle formed by the longitudinal center lines of the bodies. v

When the car is on straight track, the vestibule member 8 will'be maintained by the links 14 in `such a sition that the transverse center line A t ereof will be at right angles to the longitudinal center lines B of the bodies as ,shown in Fig. 5 ofthe drawings, As one body of the car moves from a straight portion of the' track. to a curved portion the links 14 .and vestibule -8 will move to the positions vas shown inl Fig 6 in which position the transverse center line A of the vestibule`member .will bisect the` angle formed by the longitudinal center lines B of the adjacent bodies. When ,two adjacent bodies are on a portion of curved track the4 links 1 4 and vestibule 8 55 are in the positions as shown in Fig. 7 and ^theetracnsverse center linel of thevestibule member will bisect the angle formed` by the -;.longitudinal center lines B of the bodies. -le memberv is` maintainedin one 'of the positions shown in Figs .5,6 or 7 `or anyv otl'ugr position by the'links 14, lmti'l such tiineas the relative' positions of the bodies'jare changed 'from' any of the posif 65, ltions justfl'referredto.

, It will I said member for moving ysaid member when be understood that-many changes may be made in the device without depart- -ing from the spirit and-scope'of the i11ven tion as defined in the appended claims.
