A supportingor 'carrier structure formed"`of" elements suitably "securedftogether isdn'dicated generally'bynumeral I4.'

One or more berth pans -32 l are pivotally mounted in the `carrier `structure to. swing into. a horizontal prone position for` occupancyl or into vertical storage position. with'. the bottom Wallsflush with the front walliia'ces of thecarrier structure. The berth pans are formed with 'spaced` marginal Walls-3l!` at eachv end andspaoermem-v bers 36' are xedbetweensuch pairs of. end vvall's,A see. Fig.' 14.. Aligned pins 38Iproje'ct through.v openings in. the end walls 3,11` and/associated spacer .members` ililand` are .Welded to plates 401i fixed by.- screws 42v against` the inner faces. of.the., inner members .34.

I' 3 wall of the carrier structure in which mechanism operable for swinging the berth pan-s is housed.

The mechanisms for swinging the berth pans on their pivots are similar and the same identication will be applied to similar elements thereof. A gear'casing 44 is secured in one of the end compartments I6 by bolts 46 and is formed with bearings 48, 59 and 52. The hub of segmental drive gear 54 is rotatably mounted on a cylindrical bearing 56 fixed in bearing 48 and has an arm 58 xed to the adjacent pan end wall by bolts 59. Berth pivot pin 38 extends into a bearing shell 55 carried in a-recess in one end of bearing member 55. Gear 54 meshes with worm gear 62 fixed on one end of shaft 64, and gear 66 on the other end of suchshaft meshes with gear 68 on shaft 12. Bearings 59 and 52 on casing 44 support shafts 64 and '|2. The shaft 12 extends outside of the end wall of thesupporting structure of the berths and has a handle,

16 xed to the projecting end thereof by pin 18. Gear 54 is formed with an arm 1|) and berth counterbalance spring '69 is connected at its ends to arm 18 and the adjacent side wall of the carrier structure. The mechanisms for pivoting the upperV and lowerberths are substantially identical except of course they are arranged to operate in reverse directions to obtain similar berth swinging motion. v

Rotation of handle 16 will rotate shaft l2 therewith and through gear |58, shaft 64 and gear 66 will ldrive gear 54 and berth carrier arm 58 to swing the berth on its pivot. This form of gearing is of a self-locking character such that the berth with the spring counterbalance will remain in any position'of its pivotal arc when operation of the handle ceases and, at the same time, it is very sensitive to interference to movement of the berth as such resistance will be immediately felt by the operator so that he can cease operation of the mechanism upon such occasions. Such interference can be caused by mattresses 88 in the berths, by the bedclothes (not shown) or otherI Vparaphernalia that might be caught between the berths and the walls of the supporting structure. 'Ihe gearing is also of a reduction character such that little manual effort is required to swing the berths on their pivots.

In order to permit freedom of pivotal movement of the berths it is necessary that they be spaced apart when in vertical stored position and also that they must be spaced beneath the top wall of the supporting structure at the free end of the upper berth. It is contemplated to close` these spaces with iiaps 82 and 84 and to automatically operate such flaps so that they will be flush with the bottoms of the berth pans when in stored position and moved away from such position to permit clearance when the berths are being moved away from stored position. The mechanism associated with the berths for operating the iiaps are different.

The upper flap 82 is secured to the top wall by piano hinge 86. One end of the flap has an angle member 88 xed thereto in one portion ofwhich slot 98 is formed for receiving pin 92 xed to actuator arm 94 fixed on shaft 96. Shaft 96 extends through and is suitably mounted on the inner end wall of one of the end compartments IG and has fixed thereto, within the end compartment, gear 9S that meshes with idler gear |88 suitably mounted on shaft |02. Drive gear |84 meshes with gear |90 and is xed lon shaft |96 which also has bell crank |98 fixed thereto. Shafts |02 and |86 are mounted in 4 journals 89 xed to the adjacent faces of walls I6. One arm of the bell crank carries a roller ||0 adapted to be engaged by an abutment ||2 on one end of the upper berth pan and the inner end wall I6 is provided with an arcuate slot through which the roller projects. The other arm of the bell crank has arubber "coated weight ||4 suspended therefrom by rod H6. As the upper berth moves into stored position, abutment ||2 will engage roller ||9 to swing the bell crank anti-clockwise causing gear |84 to rotate anti-clockwise and gear |89 to rotate clockwise which last mentioned gear in turn will drive gear 98 anti-clockwiseto swing arm 94 downwardly to close the flap due to the sliding pin connectionvtherewith. As the berth moves away from the4v bell crank,` weight lili will move gear |84 clockwise and idler gear |88 will move gear 98 clockwise to raise the iiap sufficiently for the berth toplearthe same. The unanchored vend of angle member 88 terminates short of the adjacent end of flap 82 so that the portion 93 of `the ilap can engage stop member 9| on the endof pan 32 to limit inward swinging of the flap beyond a position flush with the bottom of the berth pans when in stored position.

The lower flap 84 is pivotally connected to the closed position -with relation to the opening between the berths. As flap 84 is hinged to the lower berth, it will move therewith and will be swung on its hinge I8 by the link connection so that it will lie parallel with the front 'of the berth "i when the berth is in prone position. Thus, when the berth is in stored position, ilap 84 will lie ilush with the bottoms of the two berths and will close the opening therebetween and when the' lower berth is in prone position, the ap will lie in advance of the front wall of the lower berth in parallel relation therewith. The link retains the flap in substantially vertical positionin any position of berth movement.

The mechanism for actuating the upper berth `is of such a nature that, when desired, the berth can be moved to below horizontal prone position so that the attendant can apply or remove the bedclothes while standing on the oor and without undue reaching or the use of a stool or ladder, such position being shownin dotted lines in Fig. 5. When the upper berth has reached prone horizontal position, detents A|30 will engage in openings in the end wall structures as they are xed to rods |32 normally urged in such engaging relation by spring |34 bearing against the bracket |36 fixed to the inside ofthe berth, see Figs. '7 and 10. Rods |32 are fixed to spaced rack members |38 that engage with gear |48 having a bearing shaft |4| carried by bracket |5|. Release mechanism is associated with one of the detents to remove the same from locking position in the opening in the' end wall of the supporting structure when it is desired to move the upper berth below horizontal position. Such release mechanism includes a lev'er |42 having head` |44 at one end for engaging the'v detent |30.` Thisl `such bracket and lever so that the lever `head |44 is normally urged away from the detent. An

actuator for the lever in the form of a camming rod |52 `extends through the front wall of the `end structure of the bearth carrier structure and the outer end thereof is -enlargedto form a knob |54 by means of which the rod can be manipulated. When the knob is pushed to its innermost position, the camming rod |52 will rock the lever |42 Aso that the head |44 will press detent |30 out of the opening in which it extends when locking the berth in horizontal position. As the two detents are interconnected to operate simultaneously in opposite directions, they will both be withdrawn when the release mechanism is actuated to disengage the associated detent. The `camming rod |52 is slidably mounted in sleeve |56 suitably secured to the inside face of the front of the end wall of the supporting structure carrying the berths.

The upper berth is provided with a Vlee rail structure formed of sections mounted and connected in `such manner that the rail sections will shift while swinging the berth into and out of the mounting structure to clear normally interfering parts thereof. Front lee rail section |60 has depending legs |62 iixed thereto that are pivotaly mounted on brackets |64 xed to and projecting above the front wall Vof the upper berth. The end lee rail section |66 has a rear leg |68 mounted at its lower end on pivot fixed to the adjacent end wall of the carrier structure. The forward end of rail section |66 is connected to an end of rail `section |60 by pivot pin |12. As Vthe end section of the lee rail is Vmounted on pivot |18 Xed lto the carrier structure and is pivotally connected to the pivotally mounted front rail section |60, the front rail section will be swung downwardly and inwardly relative to the berth as the berth swings toward stored position in the supporting structure. As the upper berth is swung downwardly to horizontal posi- Ation for occupancy, the end lee rail section,

through its pivotal connection with the carrier structure and the front rail section, will cause the front rail section to swing in an upward and outward direction relative to the pan so that the legs |62 will be in vertical position when the berth is in prone horizontal position. Thus, the lee rail structure shifts its position, to clear flap 82,' which is moving relative thereto while the berth is being swung between vertical and horizontal positions.

The upper berth is provided on its front face with means for anchoring a ladder either in position for use or in stored position. The ladder is formed of side members |14 and rungs |15 pivotally connected together. The legs are provided at their upper ends with looped head members |16. The loops are pivotally secured on the front side of the upper berth by bolts |18 so that the ladder can be swung to a vertical or horizontal position. When the ladder is swung to horizontal position, the side members will lie in close proximity and one leg can be held by clip |80 secured on the side of the berth. When in stored position, the ladder will swing up or down with the berth so that it will be housed in the berth supporting structure behind flap 82.

Bedclothes retainers |82 are hinged along one edge to the rear side of the berth pans and are provided at their opposite edge with rollers |84 engaging `in `vertical .guides |86 xed to room- Brackets |88 are 'provided on the lower berth for engaging rabutments |90, .adjustably carried by brackets |92 xed to the supporting structure, to limit `downward pivoting of the Vberth beyond horizontal. The berths are supported by links |94 secured to Vtheir `ends andito the adjacent end walls of the supporting structure.V
