assignors to Edward G. Budd Manufacturing Company, Philadelphia, Pa., a corporation` of Pennsylvania Application June 5, 1940, Serial No. 338,887 1o claims. (C1. 165-340) The present invention relates to railway cars.

Specifically, it concerns a novel arrangement of seats, compartments, machinery, etc., in a vehicle of the double-deck type, whereby an increased number of passengers may be accommodated in comfort and wherein the available space is utilized to good advantage.

The invention includes in part providing an upper deck extending substantially throughout the entire length of the car at one uniform level, together with a lower deck-occupying the portion of the car between the inner ends of the wheel trucks, said lowerdeck having its floor at a level considerably below the level'of the tops of the wheels.

Entrances may be provided at a convenient level at the center and at each end of the car, and Stairways within the vehicle provide means for giving access to any part thereof.

Other features `and advantages of the invention will be clear from the present specification and the drawings accompanying the same and forming a part thereof, wherein one preferred form of the invention is disclosed, together with a slightly modified embodiment thereof.

In said drawings:

Fig. 1 is a diagrammatic side elevation, partly broken away and in central ,longitudinal section, of a railway car embodying the invention;

Fig. 2 is a diagrammatic sectional plan View thereof, the section being made on the horizontal plane indicated by the line 2-2 of Fig. 1;

Fig. 3 is a fragmentary diagrammatic sectional plan view of the same, one end being broken away and the section being made on the horizontal plane indicated' by the line 3-3 of Fig. l;

Fig. 4 is a diagrammatic cross sectional elevation on an enlarged scale, made on the plane indicated by the line 4-4 of Fig. l;

Fig. 5 is a similar section made on the plane indicated by the line 5-5 of Fig. 1;

Fig. 6 is a similar section made on the plane indicated by the line 6-6 of Fig. 1 and partly broken away; and

Fig. 'lV is a diagrammatic fragmentary side elevation, partly in central longitudinal'sectiom'of a slightly modied form of car.

, In al1 the figures, similar elements are cated by the same reference characters.

vReferring first to the form illustrated in Figs.

indi- 1 to 6, it will be noted that the car is mounted on the wheels l `and has two decks therein, namely a lower deck 2 occupying the central portion of the car between the innermost wheels, and an upper deck 3 extending substantially throughout the entire length of the car. 'Doors I are provided at each end of the car, as shown, and additional doors 5 are located in the central portion of the car so as to provide a relatively large area for receiving and, discharging passengers at stops.

Stairways 6 are located adjacent the doors 4 to give access to the upper deck 3. These stairs lead to an intermediate platform 1 from which other stairs .8, at right angles to the stairs 8, lead to the upperdeck 3. At the center of the car the doors 5 give direct access to the deck 2 at the level thereof, and in addition provide access to the upper deck 3 by means of the stairway 9 which connects the two levels.

Suitable windows I0 are provided at a convenient level above each deck, and a suitable number of seats is located wherever space is availablefor the same, on each deck. For example, in Fig. 2 two groups.. each comprising twelve double seats Il, are arranged along one side of the carand two groups of thirteen double seats each are arranged'along the other side, these seats occupying most of the available space on the upper deck. Over the low end of the stairway 9 two single seats l2 may be provided on the upper deckin addition to the said double seats.

A suitable protection such as a railing I3 may ,surround the stair well, as indicated in Figs. 2, 5

may be used for any desired purpose, for example, for toilets as indicated in Figs. 3, 5v and 6, each toilet I6 being equipped with a suitable door I1 and window 20, and provided with a seat Il and wash stand I9. A partition 2|, here forming a continuation of the riser of the fifth step, may be placed as shown in Fig. 5 to constitute one of the walls of the toilet, thus leavinga space 22 under the flrst four steps which may be used `for any purpose, such as for the storage of supplies, or for housing some of the equipment of the car.

Referring now to the right hand end of Fis. 1, it will be seen that there is an additional floor 23 located at a level slightly above that of the wheel movable louvres or grilles such as 29 at its endsn to give access to its interior and provide ventilation, the compartment 28 serving to house certain equipment of the car, here-shown as air conditioning means 30, although it will be understood that other equipment may be housed therein if desired.

Astairway 3| leading from the upper deck to a further floor 32, somewhat above the floor 23,

' forms at the same time a portion of the enclosing wall of compartment 28. n the oor or platform 32 may be located additional seats 33 for any desired use, either to accommodate passengers or train crew, as may be expedient.

An air passage 34 having a tapered end portion 35, opening at the end of the car and covered by a suitable grille 36 or the like, provides a` protected opening for air to serve the apparatus 39 in the compartment 28. It is clear that the direction' of air flow through the screens 29 and 36 will depend upon the direction of motion of the car, and that for instance in the example illusl trated. the air will enter at 29 and leave at 361. 4

Motive power for the car may be provided by the power plant 31, which may consist of an electric' motor or a Diesel engine, according to need. In order to economize space, when a Diesel'` engine is used, said engine may advantageously be of the horizontal cylinder type. The compartment 38 for housing said power plant may be located on the iloor 39 at one end of the car and at a level slightly above that of the top of the corresponding wheel truck. This -compartment preferably extends entirely across vthe car and has large side openings for cooling air, covered by suitable screens or grilles 39. v

An air intake passage 40 communicates with the compartment 38 and opens at the front of the car, with a suitable screen 4| protecting its said opening. It will be noted that this passage 40 is defined between the floor 39 and a second floor 42 a short 4distance above the other oor, and that the bottom of the stairway 8. also forms a part of the wall or ceiling of said passage 40 and chamber 36.

Seats for the use of the operator of the vehicle may be located on the oor 42, as shown at 43y y for example. Suitable windows 44 will be provided at the ends of the car, and it is of course obvious that the mechanical and electrical features of the car may be arranged in the customary way to make it possible to operate' the car from either end.

Referring now to Fig. 4, trap doors 45 and 46 .have been shown above the stairways 6. The

trap door 45 is shown in the open position, in which position it is possible for patrons to enter through the opened doorway controlled by the door 4 and-pass up or down theq corresponding stairway 6 and the connecting stairway 8, while passage to the other stairway 6, whose door 4 is closed, fis barred' by the :closed trap door 46. In this way confusion of the passengers is prevented, as they can use only the stairway on the open side of the car. Of'course where there isa loading platform at both sides of the car, both trap doors and both v multaneously, to aiord greater speed of loading and unloading.

'I'he car described hereinabove is primarily suitedfor operation as a single unit. When it is desired to entrain two or more cars, it will be preferable to embody a slight modification in the design, which may then be constructed as illustrated in Fig. 7.

It will be seen that here the car has a flat' vertical rear end wall 48 having an opening 41 therein, which will aline with a similar opening I deck car at present in l increased seating capacity,

in the adjacent car entrained therewith, thus making it possible for passengers and crew to pass from one car to another. Obviously the remaining end of the car shown in Fig. 7 may be either like the one illustrated at 48,or like one of the ends of the car shown in1Fig. l, depending upon whether the car is to be placed 'at an end of a train or between two other cars thereof. In other` respects the car shown in Fig; 7 may be substantially identical with the form described in the preceding figures.

The operation of the invention will be understood from the structures described, and may be briefly summarized as follows:

' The car is driven by the power plant 31, under the control of an operator at one end of the car and access to all the seats may be had by means of the central doors 5 and the end doors 4, in combination with the stairways and aisles.

By proper manipulation of the trap doors 45 and 46 the passengers may be guided automatically to the correct doors at stations. The seats on the lower deck may be used for some particular purpose, for example, smoking may be permitted on the lower deck and prohibited elsewhere in the car, if it is thought desirable. The toilets are located centrally in the car and are readily accessible. The spaces over the trucks, where only a single deck of adequate height for the accommodation of passengers can be placed, provides sufficient room for compartments of lower .height for housing the power plant, air conditioning mechanism, and the like, and for the storage of luggage or supplies.

It will thus be seen that the present car has many advantages over the conventional single general use, namely it has provides a separate section of the car which may be used to accommodate smokers, and has ample room for the necessary machinery and equipment, while at the same time maintaining a pleasing appearance and providing ample facilities for rapid loading and unloading.

While a preferred form of the invention has been disclosed herein, together with a slightly modified 'form thereof, it shouldv be understood clearly that the precise structures illustrated and described are highly diagrammatic and are given solely in an illustrative sense, as distinguished from a restrictive one. Numerous alterations, additions and omissions may be made therein without departing from the invention, which is defined solely in the following claims.
