Application filed Kay 27,

To all whom it may concern:

Be it known that I, WALTER S. ADAMS, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Articulated Cars, of which the following is a specification.

One object of my invention is to construct an articulated car so that the body of each section of the car is carried on a single truck and the abutting ends of the sections of the car are carried by a truck common to both sections.

A further object of the invention is -to construct the car so that the passageway between the sections of the car will be wide and unobstructed.

The invention also relates to construetions, which allow for the enclosing of the connecting portionbetween the two sections without interfering with the free movement of the sections, due to curves and unevenness of the road bed.

In the accompanying drawings:

Fig. 1 is a sectional elevation of'the connecting portion of my improved articulated car, the section being on the line 1-1,

Fig. 2;

ig. 2 is a plan view;

Fig. 3 is a sectional plan view on the. line 3-3, Fig. 1;

Fig. 4 is a sectional plan view on the line H; si Fig. 5 is a detached perspective view, partly in section, illustrating the articulated portion of the car above thetruck;

Fig. 6 is a"detached perspective view of a portion of the bolster of the truck with the center bearing;

Fig. 7 is a detached erspective view of one of the se ental bo y bearingsthat. fits in the center caring;

Fig. 8 is a transverse view, showing the center bearing in section on the line 8-8, Fig. 4; and

Fig. 9 is a side elevation of my improve articulated car.- v

The body of the car is made in two sections 1 and 2, which are supported at the oint of articulation by a truck 3, of the our wheel type in the present instance. The truck? has a bolster 11, on which is secured a. cup-shaped center bearing 4, in which is a central projection 4. Fitting in the s ace between the central projection and the eep flange 6 are two segmental center or PHILADELPHIA, PENNSYLVANIA, A oonronnrronor rnn vnn'rrcura'rnn can.

' bearings and 8. The center bearing 7 is secured to the frame 9 of the section 1 of the car, and the center bearing 8 is secured to the frame 10 of the section 2. as shown clearly in Fig.1. Bythis construction, both sections'articulate on the center bearing of the truck 3.

The center bearings 7 and 8 are beveled at each end to allow clearance when the car is passing around a curve. The car body center bearings 7 and 8 are shouldered to receive the head of a center pin 5, which extends throughan opening in the projection 4* of. the truck center bearing'and is secured in position by any suitable means. The ends of the roofs 1212 of the sections 1 and 2 are beveled substantially on the same line as the center bearings 7 and 8 to allow clearance when the car is-turni-ng curves.

The floors 13,13 of each car section are cut away at the end so that, when the two sections are coupled by the truck, a circular opening is formed in which is mounted the circular vestibule 14, which is made in two semi-circular sections 14 and 1 1*, having a division on a transverse line, as shown clearly in Fig. 3. The sections 14? and 14 of the vestibule rest on the frames 9 and 10, respectively, of the car sections. At the periphery of the floor'15 of each section of the vestibule floor is a segmental wear plate 15", which rests on segmental strips 16, projecting from under the" floor of the two car sections. In order tohold the floor sections in-place, a segmental hold down strip 17 is secured to each car floor, which overlaps the floor of the vestibule sections, as shown in Fig. 1. H Y

At the meeting edges of the two sections of the vestibule are-vertical frames 19. The lower member 18 of each frame is angular in cross section and forms the sill of its vestibule section. The vertical members 20 of the frame are in the form of flanged channels and are at each side of the wide passageway of the vestibule. The u per member 21 of each frame is also in the orm of a channel and is at the roof of the vesti bule above the heads of passengers.

When the two sections of the car are coupled together, the two frames 19-19 are in contact on a transverse line through the vestibule, as shown in Figs. 1 and 2. Secured to each frame 19 are segmental side plates 22. These plates are attached to the outer flanges of the side members 20 of the frames, while straight reinforcing plates 23 are attached to the inner flanges of the side members of the frame and to the inner edge of each segmental plate 22, as shown in Figs. 3 and 5. The straight plates 23 form the inner walls of the vestibule. The plates 22 and 23 on one side of the vestibule are connected to the floor sections 14 and 14 and are also connected to overhead plates 24 and 25, which are secured to the flanges of the upper members 21 of the frames 19,

and also to channel bars 26.

The construction hereinbefore described makes a substantial two part vestibule frame.

The ends 2i'2i' of each car section 1 and 2 are made of sheet metal, bent in cross section, as shown in Fig. 3, and having curved surfaces 28, which are in contact with the segmental side plates 22 of the vestibule sections.

The frames 19 of the vestibule sections are connected to the end of their respective car the ends of the car body and the segmental plates of the vestibule when the vestibule section is turned to an extreme position.

The two vestibule sections are connected together at their tops and bottoms by rods 31. One end of each rod is pivoted to a fixed bearing 32on one section and extends freely through a bearing on the opposite section A spring 33 is located between this latter bearing and a collar on the rod so that the two parts of the vestibule are held together yieldingly and can move'vertically and laterally to a given extent to accommodate any unevenness in the roadway.

A hand rail 34 may be located at each side of the vestibule for the use of passengers in passing from one section of the car to the other.

The roof of each car section extends down to the upper surface of the overhead portion of the vestibule sections, as shown in Fig. 1, and may be provided with means to secure a sliding fit between the parts to prevent drafts.

When two sections of the car body are mounted on the center bearing 4 of the truck 3, side centering posts. 35, which project upward from the truck bolster 11, enter notches 36 in the lower members 18 of the frame 19, as shown in Figs. 3 and 8. This construction causes the vestibule to turn with the truck in passing around curves and keeps the joint between the two sections of the vestibule always closed.

rectly above the central truck and is controlled thereby so that it will turn with the truck. The side members of the vestibule fit the openings in the end of the car sections and the floor of the vestibule is on the same level as the floor of the car sections.
