Aafford clearance therefor.

course, being cut away beneath said plate to t Secured on said pivot plate near the middle and lower edge thereof, is a locking pin 11, on which is secured a roller 12, which tracks in said groove A, as shown in Figs. 6 to 9, and Fig 13, and serves as a lock for the seat in either of its adjusted positions by engaging beneath the lower end of the rib 4, when the pivot pin and roller are at either end of said slot, and, during the passage of the pivot pin and roller from ene to the other end of said slot, acts to ride upwardly in the groove B, and thence downwardly in the groove C, during the inversion of the seat. As shown also, the cani plate is provided at its forward end with an outwardly struck integral hook or detent 13, adapted to receive therein the edge of the pivot plate, as shown in Fig. 7, and said edge is curved upwardly and forwardly to near the extremity to slide thereover during the return of the seat to normal position, and a relatively short straight shoulder 14, is provided at the end of sald pivot plate to rest in said detent, as shown in Fig. 6, to afford an additional lock for the seat at normal position.

The mattress frame comprising tive articulated sections, is foldable upon said seat when inverted, and at all times, when folded, is supported wholly thereon. Said mattress frame comprises alternate long and short sections, as shown in Fig. 5, and indicated by 16, 17, 18, 19 and 20, and is constructed of angle bars, the ends of the angle bar sections being pivotally engaged together through the webs, while the flanges thereof are arranged to abut, as shown in Fig. 1, so that when the mattress frame is extended, the abutting ends of said sections hold the fraine as a whole in a common plane.

As shown, the seat frame is provided on its under side, at each rear corner, with a downwardly extending bracket 15, which, when the seat is inverted, as shown in Figs. 3 to 5 inclusive, projects upwardly and outwardly. yRigidly secured by riveting or other suitable means on the under side of the mattress frame sections 17 are downwardly projecting lugs 21, which may be of any desired length, and which are pivotally en gaged on the extremities of said brackets 15, b means of a bolt or pivot pin 22, extending through both, so that, when fully ex tended, said mattress frame section 17, is elevated a desired extent above the upper end of said biacket.

Iligidly secured at approximately the eenter of the end of the seat frame and projecting downwardly therefrom, is a grooved guide plate 23, which projects below the seat frame a suitable dlstance andis provided from a point adjacent the seat frame to the rear end thereof, with a downwardly andf forwardly inclining slot D, which, at. its

lower extremity, is turned horizontally affording a locking offset in the slot. Secured at each end of the mattress frame section 16, is a pin and roller 24, shown in Figs. 1 and 5, and in dotted lines in Fig. 3, said inclined slotI in said guide plate and the position of said guide pin and roller on said mattress frame section 16, being such that when the frame is extended,',the turning of the short section 17, to a horizontal position acts to swing the long section 16, upwardly simultaneously thereby moving said pin and `roller along the slot and into the short horizontal extension thereof at the extremity of the guide plate to afford a lock.

As shown, a downwardly curved bar or pipe, 25, engages at its ends the lug 21, before described, and extends therethrough to afford the pivot inthe bracket 15. The second long section 18, is articulated as before described, at its inner end with the outer end of the short section 17, and in a similar manner the outer long section 20, is articulated with the intermediate long section 18, by means of the short section 19, which art-iculates with both and the said members of which are connected transversely by means of the downwardly curved bar or pipe 26. A foot rail 27, is pivotally supported at the extremity of the outer section, as shown in Fig. 5, to hold the bedding from sliding over the foot of the bed.

Pivotally engaged at one end with the short frame section 17, is a link 28, which'- pivotally engages the upper, shorter end of a lever 29, pivoted on the outer end of the intermediate long frame section, and in a similar manner a link 30, pivotally engages the second short section 19, and vengages the short upwardly extended end of a lever 31, fulcrumed near the outer end of the outer frame section. The relative lengths oflsaid links and the extended ends of said levers, are such that when the bed is opened out- Ward1y,`as shown in Fig. 5, said levers 29 afford sup orting legs' for said sections, but when the bed is folded inwardly from the end by substantially rolling theI mattress frame inwardly progressively, said legs fold in closed relation, as shown in Figs. 3 and 4. Means are provided for positively locking the Inattress frame in folded relation on the seat. For this purpose, spring arms 0r and 3l, are projected down automatically to y plates 32, each provided with an inwardly` ,1,20

directed hook 33, near its extremity, and an extension 34. for manual engagement'. eyond the hook is provided on t e seat frame, and, when the seat is inverted, extends'up wardly upon each side the mattress frame 25 as the same is folded inwardly; f Engaged by metallic straps 85, on tham derA side of the intermediate long frame sec-1 tions near the middle thereof, are laterali2v projections 36, shown as a rod `of metal bent V toafford a loop projectin beyond said frame members. Said' mem )ers are pivotally supported in place so that `when the ,bed is extended, asshown -inFig 5, the same swing downwardly' and cannot injure the person. 'hen the bed frame is rolled up or closed v'upon theseat,as shown in .,Fig. 3, however, the operator engages each ot' said inembersor projectionsrand swings .the same outwardly, as shown, into engagement with the hook 33, as shown'in Figs. 3,10 and 1l. The operation is as follows: lVhen the seat is in normal position, :1s-shown in Fig- 2, thel folded mattress frame and the be d ding are supported wholly upon the seat and beneath the saine, and aI fall-or front board 38, secured at the front of the-seat, as shown in Fig. 2, serves-to lentirely conceal the mechanismsupportedbehnd lthe same. .When it is desired tt'nopen t-hebed, theoperator engages the frontof the seat frame, and pulling thesame slightly for ward, lifts .the seat wit-h1.; `the.consitruotion SupportedA thereon, whiclr beingv approxi- .inat'elybalancedV uponZthepivot-LAl plu and roller, may be readily inverted-andas the sent is turned over, the lockingfpn and roller moves. upwar-dly in the 'groo \eB,bin the eam- -plate,' the projection" (i, ybeing roundedv to prevent the locking.roller-catehing thereon at thebeginningof the'upiva'rdV movement. The pressureapplield in .inverting the-seat, causesthe pivot'pin .agd'roller to nove outwardly to near the .forwztm'idpf theslot/A, .and having 'passed the highest point-"therein-` (at which -time ,tbe. looking roller' passes-over the upper end of the ri 4,-andengages on the opposite A"side ther'eof in the groove C), the movement continued until the locking roller reaches' the lower end of the rib ft, permitting the pivot roller to move `downwardly .to the forward extremity of the'sllot A, and the pivot roller to engage beneath the end of the'rib 4. The seat is now locked .in inverted position and cannot be moved except reversely and by fi'rst pushing the seat slightly inward to elearthe locking,r roller from the lower'. end of t he rib 4. The

' latches or projections 36, are now released by pressingr on the extended end 34, of the spring hooks, and the outer'sections of the hedfraxue are swung outwardly and downwardly, as illustrated in Figs. 4 and 5, successively and downwardly, thus projecting the legs 29 and 31, into supporting.. positionves, shown in Fig. 5, and net-ing conjointly as a lever to swingthe short'sections 17, upwardly, thereby eleA vatin ,and pushing the long section 16, iu-

ward y, moving the guide rollers upwardlyr in the inclined groove in the guide plate to the top thereof and into supporting position. In this position the bed is fully ex tended for use. The foot-board 27,' may now be turned up, and` of course, the fall or downwardly to a positionclose aga-inst the seat frame. The projections 36, are again engaged upon the spring hooks, and telseat may be returned to normal. puring fe 'return to normal position,the edge of the` pivot' plate engaging in the -hookeddtent-attorded on the front end 'of the cam plate, is guided' thereby and substantially locked from anyvmovementway from said' cam plate. Y i Y' Of course, we appreciate that numerousl details of the construotion' mayv bet'aried. l.
