(ci ics-340) The present invention relates to improvement in railway coaches The principal object of the invention is to provide a passenger coach body having longitudinally and vertically spaced sections or compartments with easy access therebetween for the passengers in order to provide more comfortable and diversified'travel accommodations therefor.

Another object of the invention is to provide an observation dome intermediate the ends of the roof sections of such height relative to the end roof sections and provided with end and side 'windows in the observation dome and seats beneatn the dome on an upper deck of the car in order that peopleof normal stature when seated I in these seats will .have' clear view through the end window's above the end roof sections and a" clear view upwardly and downwardlythrough the side'windows oi the dome".

The means'by which the above object and other advantages are obtained will become apparent by reference to the following detailed description and drawings illustrating various features and modifications of the invention.

Figure I of the drawings is a side elevation view of one: side of the coach body. I

Figure 2 is a side elevation view of the other side of the body. I

2. 11 of another modification with parts broken away.

As best shown in the'various figures of the drawings: the coach body comprises vertical end walls I having central doors 3, vertical side walls 5 having windows], doors" H at the end and incurved lower skirt portions l3 serving as side sills. arcuate roof portions l5 adjacent the ends joined: to the end and side walls, and an intermediate. observation dome l1 formed by a built-up central longitudinal hollowmember l9 located in a plane? above and intermediate the end roof portions l5 and having downwardly curved end portions joined to the end roof portions I5 and inwardly;- curved end and side windows 2I-23 between the central member lfl and adjacent end roof por tions and the upper extremities of the side walls 5.-

As best shown in Figures 5, 6, 12, 13 and 14, the sills of the central end doors 3 and members forming the floor portions 2521, in the body end sections 29-3! beneath the arcuate end roof per- A central stairway 33 extends upwardly fromthe inner end of the floor portion 25 in the end.

section 29 to one end of a depressed central cor ridor floor portion 35 of a fabricated upper deck or floor member 31 secured between the side walls 5 beneath the observation-dome [1 to form an elevated observation compartment 38. Portions- 39-4! including steps 4-2 of the member 31 ex-' tend upwardly and outwardly from the corridor floor portion 35 to side platform portions 43-45 of the member 31 located directly beneath the side windows M on either side of the observation.

dome I"! and directly beneath and between the Y end windows it-thereof; The portions 353S4l Figure 12 is a view similar to Figure 5 of a modifled arrangement.

Figure 13 is a view similar to Figure 6 of the modification shown in Figure: 12.

"Figure 14 is-an enlarged viewsimilar to Figure of the upper deck or floor member curve upwarcv:v 'ly at the end opposite the stairway 33 and are roof 1501* joined to the adjacent inner end of the tion [5.

Another fabricated member 41 having portions 49-51-53 is located parallel to the portions"- 35-394l of the floor member 31 and secured in spaced relation thereto by suitable struts, not

shown, and also secured between the side walls 51 forms the ceiling of a lower compartment 55 and tudinal side wall portion 6i and two transverse end wall portions 63-65. The upper edge of this partition 59 is joined to the ceiling member. 47,:-

modern the outer ends of the end wall portions 63-455 are joined at longitudinally spaced points to one side wall 5 and each of the lower edges of these side and end wall portions extend downwardly below each of the inner ends of the end section floor portions 252l to which each end wall portion is joined.

Floor plates 61 for the lower side corridor 5'! are connected between the longitudinal side wall portion 6| oi the partition 59'and the adjacent coach side Wall 5 at a level slightly below the level of the end section floor portions 2521. Ramp members 69-1! extend upwardly from either end of the lower side corridor floor plates 61 to the inner ends of the end section floor portions 2521.

Floor members 13 for the lower compartment 55 are joined to the side and end wall portions 6l-63--65 oi the partition 59 and to one coach side wall 5 at a level slightly below that of the fioorfi'l of the lower side corridor 51. Suitable door openings 15 are provided in the side wall portion 6| of the partition 59 to provide access between the lower side corridor 5'! and lower compartment 55.

Headlining panels H are supported on the underside of carlines 19 having openings therein and extending between the side walls 5 to support each of the end section arcuate roof portions [5. The space between these roof portions and headlining panels serve as air conditioning and illuminating ducts 8I83. These ducts are connected by the opening 85 in the hollow central dome member 19, which opening also serves as an air conditioning and illuminating duct for the upper observation compartment 38. The space between the fabricated floor or upper deck member 31 of the observation compartment 38 and the fabricated ceiling member 41 of the lower compartment 55 and side corridor 5! also serves as a similar duct 87 which is also connected at one'end with the ducts 83 and 85. Suitable openings for air and light, not shown, are provided in the headlining panels TI in the end sections 29--3 l, and in the underside of the hollow central member I9 of the dome l1 and in ceiling member 41 of the lower compartment 55. The observation compartment 38 is provided with seats 89 supported on the platform portions 4345 of the fabricated floor member 3'! so that people of normal stature may be comfortably seated in the seats 89 and enjoy a clear view above the end roof portions l5 through the end windows 2! and a clear View upwardly and downwardly through the side windows 23 of the observation dome IT. The end sect ons 29-3! and lower compartment may be provided with seats 9l'of any type desired, and lockers 939591 and the lower compartment 55 may be subdivided by means of suitable partitions, such as shown in Figures 5, 6 and 14, to serve respectively as a lounge and rest rooms.

In Figure 11 the lower compartment is partitioned to serve as a ladies lounge and childrens playroom.

In Figures 12 and 13'the lower compartment is partitioned to serve as bedrooms and the end sections are provided with parti ions 99 to form a side corridor with bedrooms opening therefrom.

It will be evident that the end sections and lower compartment may be subdivided as desired to provide game rooms, a grill, cocktail lounge, theater or dining compartments. The lower side corridor 5'! provides easy passage from end to end and access to the lower compartment 55 and the stairway 33 provides easy access to the upper observation compartment 38 so that exceedingly comfortable and diversified travel accommoda-.

tion is enjoyed by the passengers with the type of coach body described.
