The slides 8 ure joined to the rear portion of the seat f raine 6 by links 33, the rear ends of said links 3B being connected by pivots 84 with said seat frame, and the` front endl of said links being connectcdl, by pivots 35, with the front ends of the sli es v8. y The slides 8 are provided at the u per portions oi their front ends with inwer y-strnck nenibers or ster e 'latter nre in their standing` 36 adapted to engage the links 18 when t ition. For convenience, the front ends o the links 38 uro curved downwardly to adapt them for connection with the slides 8 in front of the stops 36.

The links 19 are provided at their lower nds with oblique extensions 43 which are con nected by springs 44 with oblique extensions 45 with which the rcitrcnds of the slides 8 are equipped. The tendency of the springe 44 is to maintain the bed in the extended ition shown in 1, and it willbe nneratood thst the springs assist. in the unfolding operation.

The truss 32 comprises vertical arms 46 whose lower ends are connected by a member 47, the members 48 and 47 being connected E braces 48. The upper ends of the arms sre connected .with ivots or bolts 49 carried by bracket mem rs 60 secured to and projecting beneath the end members of tlie intermediate bed section 20.'

The mettreee-frame is preferably formed of angle-bars the front end rear sections being of U-slinpe, and the end members forming the yintermediate section beinglstraight members connecting the extremities of the ends of the U-shspe'mombers. The parts nro so relisted that in the unfolded -condition the members of the section 20 nave their horiontsl flanges .resting upon the hori..ontal flanges of the resr section, es will be clearly understood from Figs. 1 Lid 2, so that the intermediate section will when the extended, and hen persllel with the intermediate section so es to be out of the wey of the front piece 3'( when the structure is in the folded condition..

If dosred, t te inks 88 ma be omitted and the forward und rearwa shitting of the carriage Dtinay be etl'ected by hand. The idea of pivoting the sont at or near its rear edge eo that the sent may be moved to a atandin position, and hoomnralfolded bed beneati the seat. in suchre ation thereto tlmt the bed maybe unfolded, or oecup `an unfolded or extended position without t le seat interfering with the use of the bed, is an important one, imuouueh ns this expedient. contributes both to the sim licit of the structure and the sanitary e ect. .from Fig. l it will be understood'that when the sent is in the standing position and thecarriage in the advanced pimition, the seat is locked, or braced, n'lainst accidental descent.
