(Cl. E- 1) 1 Claim.

yThis. invention relates to passenger railroad trains and more particularly to the arrangement of equipment for personal accommodations of the passengers and the manner of supplying fresh water to vsuch equipment.

It is the usual practice to provide each passenger car individually with the equipment for personal accommodations of the passengers therein.` Such equipment usually includes toilet facilities, drinking water `and air conditioning apparatus. Usuallythe drinking water is supplied separately to an iced cooler while the other equipment is supplied with Water from a storage tank mounted on the car. The equipment is located partly in the roof, under thecar and in room space Vwhere it is generally inaccessible and difficult to install and service.

An object of this invention is to improve railroad train structure by providing service cars containing al1 of the equipment andv space required for personal accommodations of the pas* sengers.

Another object of this invention is to provide a railroad passenger train in which all of the equipment required for personal accommodations of the passengers is supplied with fresh water by a feed line connected with a reservoir located in 'the locomotive;

A `further object of the invention is to provide a railroad passenger train with service cars located' between vpassenger cars and containing equipment including apparatus for conditioning the airV in adjacent passenger cars.

These and other objects of the invention will lbe apparent` to. those skilled in the artfrom a study of the following description and accompanying drawings, in which:

Figure 1 is a side elevational view of a portion of a passenger railroad train incorporating the invention.

Figure 2 is a horizontal sectional view of the train.

`Figure 7 is an elevational view ofthe water and yair pressure control devices.

Figure 8 is an elevational view of the air control valve taken on line 8-8 of Fig. 6.

The railroad train illustrated by the drawings is comprised of a locomotive L, a baggage car B, passenger cars P and service cars S. The baggage car is located directly behind the locomotive and is connected thereto by suitable coupling means such as that forming the subject matter of ap,- plication Serial No. 41,485, filed July 30, 194'8, by Robert Walsh Vand JaclcD. Kennedy, now Patent No. 2,601,928. The Aservice fears` are preferably located-between passenger cars and in units con.- taining one service car with two passenger cars at each endthereof. The cars can be of the character andcoupled together as show-n in Patent No. 2,462,666, issued February 22, 1949,` to Alej andro Goicoechea Omar.

The only equipment in the passenger carsk consists of chairs 1.0, or other furniture upon which passengers may recline. Passengers enter and leave thetrain through` side doors I I inthe service cars and center aisles l2. provide passageways through the passenger `and service cars. All equipment for the personal accommodations `of the* passengers is in the service cars. Such. per.- sonal equipment for the passengers includes a refrigerated drinking station I4, .hoppers I5, wash-basins t6, sink Il, .baggage compartment I8 and water tempering apparatus I 9 for conditioning air. rPhe washbasins and hoppers are arranged in toilet rooms 20 at one side and near the endsof. the service-cars, the sink is in akitchen opposite one of the toilets' and` the baggage room is opposite the other toilet room. T-he drinking station is between one of the car side doors and a toiletrroom and the water tempering apparatus is opposite the drinking station.

Equipment in the service cars-.S isY supplied with fresh water by a system in which a main supply line 21 passes through the trainV fromV reservoir meansZZ. n1 'the locomotive; to the rearmost serv-- ice car.` The, reservoir means in the locomotive, the air pressure system and theA control of the water are the subjectmatter of applicationiserial No. 113,727", led September 2f, 1949 byA Robert Walsh. The reservoir means 22 preferably' comprises. two tanks` suitably mounted in therearend of thelocomotive;

Valve devices are associatedwith each tank Vfor controlling the Water supply and theair pressure. Each water valve device includes a housing 4i! having an outletend that screwson an inlet pipe llt `leading to the `interior of the adjacent tank. Within eachhousing 40 is a spring closed valveAZ. ,and a manually operated wobble valve 43 is arranged at the outside of the casing. Lever 44 is attached to the casing on pin 45, valve 43 is mounted on pin 46 carried by the lever and spring 41 normally acts on the lever to close the wobble valve. When valve 43 is manually opened, a water supply hose, from a source exterior of the locomotive, can be inserted into the inlet end of the housing and will hold valve 42 open during the filling operation. Water can be supplied to either inlet housing to ll both tanks as they are connected by an equalizer pipe 43. The tanks have a pressure blow-off valve 49 so that air pressure in the tanks is maintained below a selected maximum. Water outlet pipes 59 extend through the top of the tanks and are open adjacent the bottom of the tanks. Pipes 59 join with an outlet pipe having a manually controlled valve 52 at its end to which a flexible pipe 53 is attached. Pipe 53 extends outside of the rear wall of the locomotive and has a coupling 54 at its end for attachment to train line 2l.

Air under pressure can enter the tanks from valve housings 55 attached one to each of the water inlet housings 49. Inlet pipe 55 is connected with the inlet 51 of one of the air inlet valve housings and pipe 59 connects with an outlet 59 of such air valve housing and is connected with the inlet of the other air inlet valve housing. Pipe 6l! and branch pipe 6l connect the second air valve housing with the upper portion of tanks 22. The air valve housings each have a vent pipe 62 attached to outlets 63. Two-Way valves 84 in such housings 55 are rotatable by handles 65 to connect the air inlet pipe 59 with pipe 58 and pipe 58 with pipes B0 and 8i for a1- lowing air flow to the tanks and this is the condition existing except when water is to be admitted to the tanks. When the tanks are to be supplied with water, the valves are turned to cut off flow through pipes 58, 99, and 6l and will connect supply pipes 56, 58 and 69 with vents 62 to thereby allow air to escape from the tanks and to cut off the source of air supply. Gauges 65' indicate the height of water in the tanks and air pressure on the water in the tanks is maintained at approximately 100 lbs. pressure. When the air system is open to the tanks, valve handles B5 will overlie and lock levers 44 to maintain valves 43 closed. But, when handles 65 are moved to release air pressure from the tanks, then their position is such that valves 43 can be opened. A pressure eoualizer valve 65 is connected with supply pipe 56 to hold the air in the tanks at the desired maximum pressure and the valve 96 is connected by pipe 61 to compressor 68 mounted in the rear portion of the locomotive in advance of the tanks and driven by electric motor 69.

The locomotive is powered by two main enginegenerator units 'i9 and -contains auxiliary enginegenerator units 'Il for furnishing the electricity required for various apparatus associated with the locomotive and train. The main units are connected with a control board 12 by wiring 13 and the auxiliary units are connected with the control board by wiring 14. Wiring connects the control board with batteries 16 and wiring 'E1 connects the control board with motor 69 for operating compressor 68 with which the compressed air line 81 is connected.

The main water supply line extending through vthe train consists of piping 80 suitably secured in each car and projecting past the ends of the cars. These projecting ends of the piping preferably have a selfclosing valve therein (not shown) of conventional type and are formed to receive quick-detachable couplings 54 on the ends of flexible hose sections 53, see Figs. 1 and 5. The piping in the baggage and passenger cars is shown as a straight length, while in the service cars the piping is composed of a straight intermediate section 81 offset laterally from the end sections 92 and joined by transversely extending sections 83 and 94.

The piping in each service car is connected with the apparatus in such car by valved feed lines as shown in Fig. 4. Feed lines 85 are connected directly with the transverse piping sections 83 and 84, one of these feed lines and one end of the other feed line having a valved outlet end overlying washbasins I9 while the other end of the latter feed line terminates in a valved outlet over the sink. Feed lines 86 are connected directly with piping section 8| and have valved ends connected with hopper i5 and washbasin I6. Feed line 81 is connected with piping section 8| and the drinking station I4, such line terminating in a faucet 89 and coiling through conventional refrigerating apparatus in the station. Feed line 89 leads from piping section 8| to the temperunit i9 from each end of which water lines 90 and 9i extend to form a circuit through the adjacent passenger cars. Valve 93 controls the flow of water through feed line 89 to the temperature conditioning apparatus for water controlling the air conditioning in the cars.

The service cars are also provided with a water tank 94 located in the baggage compartment i8 heated by an electric coil 95 or other suitable means. Water iiows to the tank from the main feed line section 83 through pipe 96 and piping leads from the heating tank to the sink and Washbasins. Such hot water piping comprises sections 95, 9?, 98 and 99, the section 98 and one end of section 99 terminating above the washbasins and the other end of section 99 terminating above the sink. Spigots IDI are fixed on the ends of the washbasin lines 85, 98 and 99 and spigots |02 are fixed to the ends of lines 85 and 99 above the sink.

It will be observed that all personal equipment and entrance doors to the train are in the service cars thereby leaving spacious accommodation for occupants of the passenger cars. It is also evident that the water reservoir in the locomotive supplies all of the water to the equipment in the service cars thereby conserving some of the space formerly required in the passenger cars.

The invention may be modified in various respects as will occur to those skilled in the art and the exclusive use of all modifications as come within the scope of the appended claim is contemplated.

What is claimed is:

in a railway train including a'plurality of passenger cars and a service car, each of which is supported on a pair of trailer wheels at its rear end and -coupled at its front end to the next adjacent forward car, and each having a body with passageways through the end walls and an aisle extending between the passageways, said service car being coupled between at least two passenger cars and including side door openings between its ends and passenger personal accommodations along the sides thereof each requiring controlled Water supply, the floors of said cars being below the horizontal plane of the wheels and relatively close to the road bed, a locomotive for the train, a water supply system for the service car comprising a fresh water storage means in the locomotive having an outlet extending through the rear end thereof, means in the locomotive for maintaining pressure on the Water in the water storage means, water supply feed piping connected to the locomotive tank outlet and extending the full length of the interior of the cars of the train to and through said service car, the piping being arranged adjacent the roofing of the cars and delivering water from the water storage means to the service car, cou- 10 pling means connecting the piping between adjacent cars, delivery piping within the service car including pipes extending laterally from and in communication with the feed piping therein and following the contour of the car to delivery points at the personal accommodations, all of said delivery piping from the feed piping conforming to and being confined relatively close to the roofing and the sides of the car, and valves in the delivery piping controlling flow of water to said accommodations.
