The marginal walls 42, 46 are preferably made of sheet metal formed- :withiaabulbi'orzzbeaded top edge 48 and with inwardly extending short base flanges-50 to the 1 under faces of-whioh is secured by welding a sheet metarbottomcover-plate; At the pivoted side of the berth pan' structure, as' shown in Figure -5, the bottom coverplate 541s continued. or upwardly as indicated at 64 to formthe pposite upstanding marginal side wall :bedro'omwis'i'boun'ded. by the car: side for the pan structure. The pan structure is reinforced by side and end W- shaped angl members 32, 34, respectively, connected together at their adjacent ends by angle pieces 36 secured thereto by rivets 36 and having their upright flanges 44 welded to the inner faces of the upstanding marginal walls. The side angle member 32 at the tree side of the pan structure is bent to conform with the contour of the bowed side marginal wall 46. The w- shaped angle members 32, 64 also have their horizontal flanges 56 welded to the inner face oithe bottom cover plate 54, which is additionally stiffened by laterally extending ribs 51 of inverted V shape similarly welded to the inside face of the bottom cover plate.

Upstanding counterbalance anchor castings 58 having an angle-shaped base attaching portion 60 are secured by rivets 62 at the pivoted side of the berth pan to the inside of opposite corners formed by the upright flanges 44 oi'side and- end angle members 32, 34, marginal end walls 42 and the extended portion 64 of the bottom cover plate 54. The beaded edge 48 or the marginal end walls 42 is cut away at this region to permit proper application of the anchor castings 58, the attaching base portions 65 being formed to iit up against the uprightv flanges .44 of side and end angle members 32, 34 with their outer faceslying flush therewith. A false. bottom plate 66 is removably attached by screws 68 to. and supported on the horizontal legs I of the side and end angle members 32, 34. The part 'II or the extended portion 64 of bottom cover plate 54 ex: tending beyond the top edge 46 of marginal end walls 42 is stifiened by a reinforcing plate 12 secured to its inner face by rivets 14 for a purpose later to be described.

The pivot pin mounting for the foldingberth pan structure comprises a relatively heavy angle member T6 having its horizontal leg I8, as viewed in Figure 2, secured by rivets 80 to the horizontal leg I0 of opposite end angle members 34 adjacent the inner or pivoted side of the berth pan. The vertical leg 82 of these angle members 16 is secured by rivets 84 to the upright vertical flange 44 of end angle members 34 and to the marginal end walls 42. The pivot structure is reinforced by a spacer plate 86 interposed between the ver-v tical leg 82 of member 16 and marginal. end wall 42, each of which is formed with aligned openings, indicated at 88, for the reception of a pivot pin 90. The pivot pin is held in place byca retainer or anchor plate 92 welded to the inner end of the pin and secured to the pivot structure by bolts 94.

The pivot pins 90 are journalled in bearing members 96 secured by bolts 98 in the proper cation on the opposite walls I2, 28 of the .room. The bearing members are. formed .with acentral cylindrical portion I00 lined with a bushing I02 through which the pins 90 extend. The berth pan structure is maintained in spaced relationto bearing members 96 at opposite sides of the room. by washers I04, I06 interposed between the bear-v ing members 96. and. the upstanding marginal end walls 42..

When theberth is in the horizontal prone position, its free side is supported at the outer ,end by a ledge member I08 secured by screws IIOto the car side wall I2, and at its inner end by a supporting link H2. The supporting link H2 is pivoted at one end, as indicated at H4 in Figure 6, to a bracket II6 secured by rivets II8 to the horizontal leg I0 of bowed side angle member 32.

hinge I58 between the i The link I I2 is bent, as shown in Figure 3, to corn form generally to the contour of the bowed end portion of the swingable side of the berth pan structure, with its opposite or free end adapted to be inserted through a slot I26 formed in the front cover plate I2I 01; a recess casting I22 extending through an opening formed in closet wall 28 and secured thereto by screws :24. As shown in Figure 4, the free end of link II2 is provided at one side with a notch i226 engageable with the upstanding lip I28 forming the bottom of slot I20 in the cover plate ii! of recess casting I22 to releasably support the swingable side of the berth when it is in prone position. The free end of link H2 is also formed at its opposite side with a second notch I36 with which a latch member I52 pivoted at I34 to the cover plate I2I above slot I20 is adapted to be engaged for retaining the link in berth supporting position. The latch member I32 is provided with finger actuated handle portions I36 and a stop I38 formed on recess casting I22 for limiting pivotal movement of the latch beyond notch engaging position.

The berth pan structure is equipped with counterbalance devices, one at each end of the pivoted side of the berth, and generally indicated at I40. The counterbalance devices each comprise a tubular part I42 pivoted at I44 to the anchor castings; 58 and a cylindrical part I46 is pivoted at I40 to bracketi50 secured by screws I52 to the transverse room wall 24. These parts are ar ranged in telescoping relation with a coil spring I54 interposed between them, the spring being installed under suficient initial compression to exert a force capable of counterbalancing the weight of the berth structure and permit its easy and controlled operation. The berth structure is also provided at its pivoted side with a bedding retainer I56 pivotally connected by means of a piano type spring hinge I58 to the upper edge portions of bottom cover plate extension H and reinforcing plate I2. The upper edge portion of reinforcing plate I2 is cut away or recessed, to p rmit sandwiching of the bottom leaf I59 of plate 12 and cover plate extension II, where it .is secured in place by rivets I4. The bedding retainer I56 is held in operative position by rollers I60 carried thereby and riding on wear strips I62 secured by screws I64 to transverse wall 24.

The berth structure may be retained in its prone and stored positions by any suitable or desired type of latch means, but such means have not been shown or described since they form no part of the present invention.

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