cinnati, in the county of IIamilton and State of Ohio, have invented certain new and useful Improvements in Railway Cars,

of which the following is a specification,

reference being 'had therein to the accompanying drawing.

This invention relates to railway cars, moreparticularly the kind used on vinterurban and steam railways.

'Ihe special feature to which my invention is directed is the provision of a structure in the nature of a vestibule which comprises an enclosure inde endent of the' structure of the cars and whic is adaptedto be mounted on the latforms of adjacent cars to form a safe ousing through which passengers may pass in going from one car to the other., `i il: vestibule structure also aords protection to the passengers in the case of. derailment or accident at the time they are passing from one platform to the other because it is in the nature of Aa separate unit which forms a complete closure around the passengers, save only for'its doorways.

Another feature of my invention is that of combining such a vestibule unit with its passengerl enclosing features with two articulated railway-cars whose adjacent ends are mounted upon the same truck, so that I produce` a novel and highly useful combination of a vestibule enclosing unit, articulated cars and a common truck for both cars.`

A further feature is the provision of connections between my vestibule unit and the bolster of the truck, so tliat as the bolster changes position on curves in the tracks the vesti u le will alsocorrespordingly change lposition to keep itself in substantially the same relation with the car latform's, and which vthemselves likewise c ange position under these conditions. In this way I have perfect Hexibility or relative movability between ;the vestibule unit and the cars and this movability is controlled by the movements of the truck bolster.,

'Ihese several objects .are carried into ractical eHect 'by the structure illustrated in theaccom anyin drawings which represent the pre erred,

orm ofv embodiment of my invention.,

In the drawings, Figure 1 is a side elevation of two railway cars, their truck and my vestibule unit.

Figure 2 is a plan view of the same with parts of the car structure and of the vestibule in horizontal position.

Figure 3 is an enlarged detail sectional view taken on the line 3-3 of Figure 1, showing the vestibule unit on the car platforms, and the spring pressed guards.

Figure 4 is an enlarged vertical sectional view of a part of the car roof structure, showing a spring pressed weather strip and the top of the vestibule unit.

Figure 5 is a vertical sectional view` on an enlarged scale of the upper part of the vestibule unit showing most particularly its top or roof construction.-

Figure 6 is a longitudinal vertical seetional view of a portion of the two adjacent cars, the central bearings therefor, and the truck bolster. I

Figure 7 is also a vertical sectional view,

in a transverse direction, showing the cen-- tral bearing for one car, the bolster and the interlocking rods between the vestibule unit and the bolster.

Viewing Figures 1 and 2, the numerals 1 I and 2 generally designate two railway cars whose adjacent ends are supported by a sin-4 gle truck common to both cars at this point. There is nothing peculiar about the car structure or the truck, in so far as concerns my present invention, further than to sa that the two cars are articulated throng their pivotal su port 'and connection with the bolster of he one truck. The platforms of the cars indicated 3 and 4 in Figure 2, with their end housings 5 and 6 apprpach one another near the central line but thence diverge one from the other to permit of the swinging of the cars in the diderent relative positions in going around the 'Ihe support of both the cars by aV single truck is best illustrated in detail in Figure .6 where it will be seen that the under beam 7 with its transverse angle bar 8 of the car 1 and the under beam 9 with its transverse angle bar 10 of the car 2 areequipped 1 with stout, hollow studs 11 and 12 respecthe spherical sockets inthe bear u: plate 1t wood doors terminate well back from these beams.

The details of the structure so far described do not enter into my invention, but, broadly speakin articulated cars, that is to say, two cars w ose adjacent ends are support/ed upon a single truck in a pivotal manner, do enter into the combination which Aforms one part of this invention, to wit, the combination of two articulated cars witha vestibule unit which forms an enclosing structure within which passengers may stand and through which they may pass from car to car.

Referring now to this vestibule unit, it is to be observed that it comprises, generally, a shell formed of walls which constitute an enclosure in the nature of a small room. 'l he preferred form of-this vestibule unit is cylindrical as seen by the wall 18 in Figures 2 and 3, while at the bottom is a floor 19 and at the top a roof 20. Sheet steel is the preferred vmaterial thou h the vestibule unit ma be constructed o some other material an of some other shape or outline than cylindrical.

The Hoor 19 rests upon the wood floor 17 of the twoadjacent car platforms and overlaps'the two platforms so as to bridge the gap between them. 'Ihere is no positive connection between the vestibule and the platforms. It may be said. to float or merely rest upon the platforms.

The vestibule, is however, connected to the bolster 15 asbest seen in Figure 7. The preferred means of .eecting this connection consists of. rods 21 which are mounted in clips or bearings 22 in the vestible and eX- tend down past the ends of the car platforms and enter sockets 23 in the bolster of the truck. The' rods have portions 24 which form handles tb enable the rods to be manipulated or lifted when it is desired to disconnect the vestibule from the bolster.

It willnow be understood that as the truck turns from side to side in following the direction of the curvatures of the tracks, the vestibule will be likewise turned, and in doing so will oscillate back and forth on the car platforms, though will not otherwise change its relative ,position to the cars.

The vestibule has doorways indicated at 25 and 26 at the sides of which wood posts 27 are erected about which the metal walls are bent and secured as seen at 28 particularly in Figure 3. The position of the posts and therefore of the sides of the doorways is such that (when the cars swing to their extreme positions as in going around a curve having say a radius of 35 feet (about the minimum radius) the housings 5 and 6 at the ends of the cars will not pass the door openings, but even under such extreme positions as here assumed, the position nearer to the openings is indicated by thedotted line aa in Figure 3.

In order to make a close fit, yet a yielding one, to allow the rocking motions of the cars, I form a pocket 29 in each structure 5 and 6 and mount therein ards 30 in the form of strips of wood w ich are urged against the cylindrical wall of the vestibule i by springs such as 31. guards hug the vestibule but permit of the necessary flexibility in the relation of the vestibule to the cars.

In order to maintain a weathertight fit between the top of the vestibule and the/ car roofs, over the platforms, I connect to the roofs a pocket structure 32 which is best seen in Figure 4, in which I mount a weather strip 33 urged by a suitable spring 34 against a rubbing board 35 mounted on the roof or top 2O of the vestibule. A rubber or other flexible packing 36 is connected to the weather strip and adapted to lie firmly on the rubbing board to more effectively kee out snow, and rain. The weather strip an the packing rub against the board 35 as the cars move along, but the weatherproof joint is retained. Each car platform roof is so equipped at the point over the vestibule as shown by the dotted lines b in Figure 3.

In .order to 'construct a gutter to receive rain and melted snow, the rubbing board 35 is bevelled at its edges 35L as seen in Figure 5, to leave a gutter 37 between it and the adjacent part ofthe side wall. A drain pipe 38 extends down inside the vestibule and empties below it to discharge the water.

It is, of course, to be understood that the numerous details I have described may be modified to suit different installations of my vestibule unit without departing in any way from my invention.

By now referring back to the introductory statement of the objects and purposes of my invention, its value and utility will be appreciated. It forms, through the office of the vestibule unit, a safe, protecting enclosure through which passengers may pass from one car or car platform to another and which protects them while within the vestibule, because it surrounds them and divides them off from the nearby portions of the car structure.

Again, this vestibule unit maintains a {irm In this way the ateatro but yielding contact with the platform struc# I tures, while it also excludes rain and wind and very largely excludes dust.

Again the connection of the vestibule unit with the truck bolster not only maintains the proper position of the vestibule with respect to the car platforms, which themselves are pivoted to the bolster, but also forms a sort of anchor for the vestibulewhich prevents it from working away from its mounted position, for while it swings back and forth 4with the swinging movement of the bolster, yet it always maintains the same general p0- sition. Y p

l regard myself to be the first to invent a vestibule unit comprising an enclosing structure and combined with adjacent car platforms.

l also regard'myself as the first to produce a vestibule unit forming an enclosing structure combined with the platform of articulated cars.

lf further regard myself as the rst to provide a vestibule unit comprising an enclosing structure combined with and connected to a railway truck. c

The utility of this invention has been demonstrated by its `manufacturer and introduced into practical use upon various railway lines.

Having thus fully described my invention, what l claim as new and desire to secure by Letters Patent is l. The combination with two adjacent cars and a supporting truck common to both cars and to which they are articulated, of a vestibule unit comprising a separate closure adapted to ride on the ad]a cent4 platforms of such cars and supported on said truck through the intermediary of said platforms, and having door ways through opposite portions of the side walls.

2. rllhe combination with two adjacent cars each' having a projecting platform and a truck common to both cars and to which each platform is articulated, of a vestibule overlapping such platforms,

supported,- thereby and positioned above the point ofA positioned to partly rest on each platform and devices which connect the vestibule with the bolster for the purpose stated. i

5. The combination with two articulated cars mounted on a truck common'to both, each car having yieldingly mounted guards, of a vestibule unit comprising an enclosure positioned to partly rest on each platform and tomake contact with said guards andl means for connecting the vestibule with the bolster 'of said truck.

6. The combination with two articulated cars mounted on a truck common to both, each car having yielding guards, of a vestibule unit comprising an enclosing structure of cylindrical form adapted to contact with said guards and also adapted to overlap the adjacent platforms of said cars.

7. The combination with two articulated cars mounted on a truck common to both, the adjacent platforms of each car having pockets and vertical guards slidingly mounted therein and each having other pockets with horizontal weather strips slidingly mounted therein and extending` transversely, of a vestibule unit comprising an enclosing structure of cylindrical form, the side walls of the vestibule being adapted to contact with the guards and the topI of the vestibule to contact with the weather strip.

8. The combination with a car platform roof having a structure provided with a recess and a horizontal weather strip slidingly mounted therein and urged outward by springs, of a vestibule unit comprising a separate structure adapted to be placed on the car platform and having a top adapted tto be contacted by said weather strip.

9. The combination with a truck bolster, of a vestibule unit comprising an encloslng structure and means for connecting the bolster with said vestibule to 'cause the latter to move in substantial unison with the bolster when dedected by thev course of the tracks.

10. The combination with a truck bolster, of a vestibule'unit\mounted above the bolster and means for detachably connecting the bolster and the vestibule, such means being adapted to cause the vestibule to move in substantial unison with the bolster when the bolster moves about its center.

.11. The combination with a truck bolster, of a vestibuleunitl comprising an enclosing structurey of cylindrical outline, and adjustf able rods-operable in the vestibule causing them to connect 'and disconnect the vestibule with the bolster.
