enrayer-son. To date, however, sleeping 'accende modations of the room type adaptedionoccupancy by more than one person have been rather expensive. In `certain' cases single occupancy rooms havebeen'occupied by two' people-but siieh an varrangement is extremely uncomfortable" nd 'the railroads cannot charge f or'the extrap son since no true Iaceommodations have been iro- Vided- Since it OStSthe railroads, ,aeltam amountto'haul Va car, Ait is obviousgthatthe greaterthe inumlcyer of passengers.r the Vlowerfthe rate perfperson canbe charged, while atl the same 4time returning a Vgreater revenue 'to the railroad. It is an object, therefore, of the present invention to provide av sleeping car having rooms on either side'of the aisle of singleoccupanoy size, yet having accommodations fortwo persons.

A further objectY of the invention 'is the provision`of a sleepingcar having singlefo cupancy size 'rooms withtwo lbeds therein.

v`A still further object 'ofthe invention is the provision of a railwaycar having completeroo'ms beds.

Yet'another object O f th invention is. ,theprovision of arailwayl car having 'vertically movable `beds which remain horizontal' at alll times Vand are rigidly supported at four points whenvin a sleeping position.

yStill another object of the inventionvis'the provision of vertically movable' bed'snarriedby ,screw means andequipped with slot closers'which 'hide the screw 'operating means.

These and other 'objects of the vinvention ,will be apparent to persons skilled in vthe art from a study of thefollowingdescription and aoeompanying drawings, in which Fig. 1 is a `sectional-view taken through the carv and showing the rooms in plan;

The partition walls at one end of the room are provided with slots 20 located closer to the side walls and aisle walls than are slots 22 formed in the partition wall I6 at the opposite end of the room and as shown in Fig. 4. Bed B #l is provided at one end with widely spaced arms 24 extending through slots 20, while bed B #2 is provided at one end with arms 26 extending through the same slots 20. The opposite ends of beds B #l and B #2 are provided with closer spaced arms 28 and 30 respectively extending through slots 22. The arms 24 and 28 of each lower bed B #l are internally threaded to engage the threads 32 of lead screws 36 rotatably mounted at their lower ends in blocks 38 and guided at their upper ends by-shaft supports 40. The shaft supports 40 and blocks 38 are fastened to and tie the partition wall I6 of adjacent rooms together, Vthereby reinforcing the partitions while at the same time forming supports for the lead screws 36. The arms 26 and 30 of the upper bed B #2 are provided with smooth holes 42 therethrough, which holes are adapted to closely engage the outer surface of threads 32 in order that the lead screws 36 may guide the arms 26 and 38. Each arm 26 and 30 is also provided with an extension 44 adapted to engage a conical extension 46 formed on the upper surface of arms 24 and 28 of the lower bed B #1. The arms 24 and 28 of bed B #l are identical, while the arms 26 and 36 of bed B #2 are also identical except that arms 26 are provided with outwardly projecting stop lugs 48, while arms 30 are provided with inwardly projecting stop lugs 50.

In order to rotate the lead screws 36 for each room in unison they have fastened thereto at their upper ends bevel gears 52 adapted to engage bevel gears 54 carried on transverse shafts 56. The transverse shafts 56 are also provided with intermediate bevel gears 58 adapted to mesh with bevel gears fastened to a longitudinally extending intermediate shaft 60. One of the transverse shafts or the longitudinal shaft 60 is driven directly by a motor 62. This motor may be of small fractional horse power due to the use of the gearing and lead screws. It is obvious that with all of the lead screws 36 for each room interconnected by gearing or similar means, they r must rotate in unison thereby causing the arms 24 and 28 of the bed B #l to be moved in a vertical direction in unison thereby holding bed B #l always horizontal. Rotation of motor 62 will, of course, be under control of a push button or other type switch located in the room with which the motor is associated.

Since the lead screws 36 will positively hold bed B #l in any position in which it is stopped, no locks will be necessary for bed B #1. Bed B #2, however, since it is not connected to the lead screws but merely slides therealong, must be equipped with locks or other holding means to keep it from being lowered when it is desired to sell the room to a single person. Arms 26 of bed B #2 may be locked in their upper or raised position by means of a transversely sliding bolt 'l0 actuated by lever 12 connected by cables or other means 14 to a cam member 'i6 accessible from the inside of the room. The sliding bolt 'l0 when thrown into locking position as shown in Fig. 11 will engage beneath stop ledge 48 of arm 26. Arms 3|] at the opposite end of the bed B #2 will be held in raised position by means of sliding 4 bolts engaging beneath stops 50 of arms 30. The sliding bolts 80 may be simultaneously operated by means of linkage 82 connected to a throw arm 84 controlled by a key or other means from the inside of the room. The locking means for the upper bed B #2 is shown in the unlocked position in Fig. 2 and in the locked position in Fig. 4. It will be obvious that with the locks as shown it will be necessary to insert a special key at three positions in each room before the upper bed B #2 can be unlocked and these locks are preferably under control of the car porter and impossible to be operated by the occupants of the room. In order to stop and hold bed B #2 in its lowered or sleeping position locks are fastened to the partition walls I6 and tie the adjacent partition walls together, thus stitfening the same while providing rests upon which the bed B #2 will be held when in lowered position.

For smooth easy operation of the beds it will, of course, be desirable that the lead screws 36 be well oiled either with grease or graphite, and since the slots 20 and 22 are necessary to accom- `modate the bed arms, it will be obvious that the cause the fabric parts to separate and the other will cause the parts to again be closed. Since these slides will be located in the plane of the bed to which they are attached, it is obvious that anyone watching the operation of the bed will never see anything except the closed fabric both above and below the moving bed.

The under surface of beds B #l and B #2 is finished so as to blend into the room decorations and may carry lights supplied by current either directly through the lead screws or through sliding contacts. In this way overhead lights will be provided for the room and due to the position of the beds in the ceiling zone the ceiling will necessarily be much lower than the average room now in use on the railroads. Such low ceiling will give the effect of increasing the dimensions of the room, that is, to a person occupying the room it will seem much larger than does a high ceiling room.

From the preceding description it; will be seen that a car has been provided with a large number of rooms therein having beds for individual occupancy extending longitudinally of the car and moving from an inoperative position in the ceiling of the room to an operative position between the floor and ceiling. In case the room is being occupied by a single person it is only necessary to fold the chairs C and close all cabinet doors, after which a switch may be operated causing rotation of motor 62. This motor is, of course, of the reversible type and when rotating in the lowering direction will cause the screws 36 to rotate in such a direction as to lower bed B #l which is directly connected to the lead screws.v The motor will continue to operate until bed B #l has been completely lowered and comes to rest upon blocks 38. Safety devices (not shown) may be applied either to the motor or to blocks 38 so as to stop rotation of the motor when the bed B #l comes to rest sistem esta the-"tineke In easethere' are tweeersrjis 'upygth'e V`1"o'0`hi the conductor or' porterwll atthe timeof tak'i'ig tickets 'unlock the toiibed 3*#2' by" rotation" 'of lock members 76v and" 841 When vthel tp'bed has been unlocked and theoc= c'pants oi? the room desire thebed in operative position thesame lowering button'or swit'chwil-l again be'op'erated ahdbedsB #l andB'tZ Will lower as'a unit until be'dB #2 cornes to Vrest-in itsepeiative position threugn the engagement' of ledges '43 'or "l'with' Stop lugs#` 9i) 'fastened 't6 the partition Walls.
