SPECIFICATION forming part of Letters Patent No. 568,166, dated September 22, 1896.

Application filed May 16,1894. Serial No. 511,393. (No model.)

To all whom it may concern.-

Be it known that I, JOSEPH A. MILLER, of the city of Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Railroad-Cars, of which the following is a full and clear description, reference being had to the accompanying drawings, forming part of this specification.

This invention has reference to an-iinprovement in the end platforms of railroad-cars; and it consists in the peculiar-and novel c011- struction more fully set forth hereinafter.

Railroad-cars, as 110w constructed, are supported on the trucks in such a manner that the car-wheels can adapt themselves to the varying levels as well as to the curves of the rails. On curves the outer rail is usually higher than the inner rail and on reverse curves the higher rail is first on one side and then on the opposite side. \Vith the long cars now in use the two trucks under a car frequently run at opposite inclinations to the horizontal line. The car is supported on the centers of the two trucks and is free within certain limits to rock on this central support. As the support for the car-body is not at the extreme ends of the car-body, but at considerable distance from the ends, the several cars in a train are connected so that when running on curves, on reverse curves, and on entering or leaving curves the ends of the cars may swing laterally while the trucks follow the changing direction of the track. WVhile this freedom of the trucks to adjust themselves to the track independent of the car-body is necessary, it produces a complication of motions that are very disagreeable to the passengers. Oar-sickness is nearly as prevalent as sea-sickness. It is caused by the transverse rolling motion of the car-body, accelerated by sudden lateral motions of the ends of the cars. These motions, when once started at some curved portion of the road or on an imperfectly lined or leveled piece of road, continue for a considerable time before the momentum of the heavy car-body is gradually brought to rest, to be again disturbed by the next change in the level or direction of the rails. Even the fast express-trains, with their luxurious appointments and vestibule connections, are subject to the excessive and disagreeable motions even on straight portions of the better roads.

One object of this invention is to prevent all unnecessary lateral motion of the ends of cars made up in a train and yet permit the required independent lateral motion of the ends on contiguous cars in a train when runnin g on curved portions of the railroad-track.

Another object of this invention is to yieldingly limit the rocking or oscillating motion of the cars of a railroad-train automatically and thus secure more steady running cars, which can be run at high speed with less inconvenience to the passengers and with greater safety.

Another object of this invention is to secure a connecting-passage from one car to the next, so that an inclosed and safe corridor connects the cars of a train and communication between the cars may be had without exposure or danger, and another object of the invention is to so construct the ends of railroad-cars that the devices for limiting the lateral and the rocking motion of the carbody and the devices for securing a continuous inclosed passage from car to car are always in the position for coupling any two cars together. The problem is to so connect the cars in a railroad-train that the trucks and the car-Wheels can freely adapt themselves to the levels and curves of the rails, while all lateral motion of the cars and the rocking or transverse oscillating motion of the car-bodies is yieldingly resisted and all excessive motion prevented. One form of construction by means of which I propose to accomplish thisend is illustrated in the annexed drawings, in which-- Figure l is an elevation of the end of a railroad-carbodyprovidedwith myimprovement, showing the open end of the connecting-passage. Fig. 2 is a perspective view, partly in section, showing the pivoted platform exten sion. Fig. 3 is a horizontal plan View of the end platforms of two adjacent cars connected together by two pivoted bars, illustrative of the manner in which excessive horizontal lateral motion of the ends of the cars is prevented while free articulating motion of the cars is secured.

ends of two adj acentcars in the position when about to be coupled and connected by my im- Fig. 4 is a top view of the proved vestibule connection. Fig. 5 is a horizontal view, partly in section, of the ends and connection between the ends of two adjacent cars on a plane above the floors of the cars, showing the cars in the position when the ends of the connecting-plates touch and before the cars are coupled together. Fig. 6 is a horizontal view, partly in section, of the ends of two cars provided with my improvements shown in the normal position when the cars are coupled together and when running on a straight track. Fig. 7 is a bottom view of two cars provided with my improvement, showing the positions of the hinged connecting-plates when the two plates are extended outward and cover nearly the largest distance between the ends of the platforms. Fig. 8 is a vertical longitudinal cross-section through the axial line of the cars of the ad jacent end platforms of two cars, showing the hinged connecting-plates.

The problem intended to be solved by the present invention is illustrated in Fig. 3, in which CL a indicate the end platforms of two adjacent cars. I; is a bar, one end of which is pivotally connected at c with the transverse end beam of one of the car-platforms, the other end being pivotally connected with the head of the spring-buffer d, secured to the transverse beam of the other car. 6 is a similar bar placed below the bar Z), one end connected pivotally with one car an d the other end with the head of the spring-buffer 61, se cured to the other car. Considering now the two cars connected by any one of the coupling devices or draw-bars, it will be seen that this connection, by means of the pivoted bars I; and e, is perfectly flexible and that the cars can readily adjust-themselves to any curves. If the car a is the forward car and enters a curve while the car a is on the tangential straight line, the end of the car a will move in the direction of the arrow X,and this movement will be yieldingly resisted by the spring buffer d acting against the bar 6, and when the end of car a moves laterally in the direction of the arrow Z the motion will be yieldingly resisted by the spring-buffer d, and thus the sudden and excessive lateral motion prevented. If now the same connection between the two ends of adjacent cars is made at the upper part of the car, preferably the hood, which usually extends over the end platforms, the independent transverse rocking motion of the cars is also resisted yieldingly by the spring-buffers, and the bodies of a train of cars are held against excessive and in dependent lateral and oscillating motion.

The form which I have adopted for carrying my invention into practical use differs in construction, but not in operation, from the illustration shown in Fig. 3, and this form, which I'will now proceed to describe more fully, may be modified in the details of constrnction without materially changing the operation and the beneficial results.

In thedrawings, 4: indicates the transverse beam forming the end of the car, or, as used in the usual construction of passenger-cars, the end of the car-platform; 5, the floor of the car; 6, the stairs; 7, doors by which a portion of the platform is closed to form a vestibule; 8, the outer walls of the car. Each end of the car is provided with the wedge-shaped plate 9, the outer edge of which extends downward to form the face-plate 10. The narrow end of the plate 9 is pivoted to the transverse beam 4 at 11, and in the drawings is shown as pivoted on one of the stanchions 12,wl1ich connect the car-platform with the overhanging hood 13. The plate 9 may be hinged or pivotally connected to the end of the car or the end face of the transverse beam 4, similar to the hinged connection of the bars I) and e at c, Fig. 1, or in any other similar practical manner. In Fig. 1 the face 10 of the plate 9 is extended down and under the transverse beam 4: and is pivoted above and below the same to the stanchion 12, which is also shown in Fig. 8 on an enlarged scale.

The spring-buffer rod 1& is pivotally connected with the inside of the vertical face 10 of the plate 9. The spring 15 bearing against a collar on the rod 14: acts to push against the plate 9 so as to swing outward, but the plate 9 may be secured, when the car end is disconnected, by inserting a pin into the hole 16 and a hole in the platform. The plate 9 is provided with the projecting bar 17 the end of which bears against the head of the springbuffer 18. \Vhen the cars approach each other to be coupled, the ends of the bars 17 are nearly in touch with the heads of the spring-buffers 18, as shown in Figs. 5 and 7, and when the cars are coupled together the ends of bars 17 bear against the heads of the spring-buffers 18 and partially compress the springs, as is shown in Fig. 6, and in this position the buffer-springs 15 are also partially compressed. The cars when so connected are free to adjust themselves to any curves 011 which the train may run, but all motions pivotal or lateral are yieldingly resisted by the springs 15 and the spring-buffers 18. The faces 10 of the plates 9, are never at right angle to the axial line through the center of the cars, but at an angle to that line, so that the lateral motion of either end of the car,which carries the plate 9 away from the buffers 18, acts like two wedges driven from opposite ends and is resisted by the friction on the faces 10 of the plates 9 held in contact with each other by the buffer-sprin gs 15. All exces sive lateral or side motion of the ends of the cars is yieldingly resisted by the combined actions of the springs 15 and the spring-but fers 18. By applying the same arrangement to the upper portion of the cars as is shown in Fig. 4 the disagreeable independent oscillating and excessive lateral motion is entirely avoided, while, when the arrangement described is only applied to the base or platform of the cars, these disagreeable transverse motions are materially reduced and the whole train of cars runs with much greater steadiness than was possible with the older form of connections. Having thus provided a flexible extension of the car platforms or floors and also of the roofs, a flexible connection on each side of the passage so formed is made by connecting the hinged floor-plate 9 with the hinged roof-plate 9' by the rod or stanchion 19, and a corrugated flexible curtain is separts act on the floor-plate 9, the roof-plate being preferably somewhat arched so as to form an arched roof for the connecting-passage.

A train of railroad-cars provided with my improvement, while sufficiently flexible ,to pass around any curves or reverse curves, will befar more steady than such a train as now connected, the rocking motion of the cars, which makes the walking through the cars so difficult and which creates the nauseatin g car-sickness, will be avoided and travel, particularly for ladies and invalids, made much more comfortable and enjoyable.
