" er1-BUFFALO, NEW 'zonn- SOFA-BED.

a citizen ofthe United States, residing'at Buffalo, in the county of Erie and State of New York, have invented anew'a'nd useful This invention relates vertible couches especially of the davenport type which have a hinged-seat adapted to be swung to an inverted position in front of the couch and afolding spring .bed brotav 9 tom which, withL the mattress carried therebed of this type, which is of a novel conby, is `adapted/ to be unfolded or extendedv to form a bed above the couch seat when the latter is inverted, and to be folded beneath the couch seat when the seat is returned toits normal position. l

The .object ofthe inventionisto produce a practical, desirable and comfortable sofa struction enabling the vsame to be produced j size bed in acouchwhich is but slightly 80 tion foldedoveronthe intermediate section. Fig. 7 isa fragmentary sectional'elevation' Fig. 9 is a section of the bed bottom on line' at a moderate cost, which insures ease of 'op-` eration, and in which the length -or greater dimension of the `bed bottom when extended or unfolded extends crosswise with refervence to the couch instead of lengthwise thereof, so as toenable the provision of a full longer than the width of the bed.

In the accompanying drawings, consistling ofthree sheetszFigure l is' an eleva' tion, partly in section, of a sofa bed embodying the invention, showing the bed bottom extended to form the bed.

rigid rectangular base portion, highornfa-- mental end pieces or arms a., and la stationary upholstered backa.

.davenport type and this frame consists of a B represents the couch seat,`iwhich-,4- as usual, consists `Of av rectangular box-like frame b and\ an upholstered seat pad yZ2- Which lsyieldlngly supported kby a suitable spring bottom contained in the frame `b. y The front board of the seat frame is hinged at its lower portion or edge to `vthe upper edge or portion of the front rail of the stationary couchl frameby suitable hinges C which permit the seatto be' lswung forwardly and downwardly frointhe normal seat forming position, shown in Fig; ?,t'oA i' the inverted position .infront of' the -sta-l tionary frame,shown in Figs. 1, 5' and 6.'

,The folding spring bed lbottomgorin'atj f tress support consists of the` usual resilient fabric D,`c0mposed of flexibly connected t linlis or of other formation, 'which'is attached at its :sides and ends to a .folding rectangular frame. This frame lis preferably made of metal angle bars and consists of inner and outer end' bars (l and con nected by folding sectional sidebars, each composed of three main or principal sections al cl2 and d3 of approximately equal length, and ashort spacing section 'd4 whichconnects the outer and intermediate sections and d2. '5* v L v The intermediate and inner sections d? d, are 4connected at their adjacent ends byv suitable hingesd5 which project-upwardly.'

from the frame when the bed bottom is -extended as shownin'FigJl, sothat when the frame is folded these hinges hold apart or space the ends of the sections to which they v are attached, to provide A room between the indicated at D.

The inner bottom frame section ably supported in theV stationary .couch frame by suitablefimeanssdasf to rise and fall, and the other sections of the bedbottom' frame are' mounted on the hinged seat so as to turn` with the seat when it-is swung 'f to and from its inverted position. In thev construction shown, the inner'section is con-w nected at its inner or 'rear edge to` links-et whichare suitably lpivoted to the ends 'ofl the stationary couch frame. These links have a pin and slot or other suitable sliding connection with the bars @Z-of the inner be bottom section, and braces or links e pivoted to the side bars Z3-have pin and slot or other suitablelsliding connections with the links e. The bars d2 forming the intermediate section of the bed bottom frame are pivoted or hinged at f in any suitable way to rigid posts f at the ends of the couch seat near the hinged side thereof, which posts project upwardly from the seat when it is inverted, and`downwardly from the seat when it is in its normal position. The seat is provided adjacent to its rear orfree edge with rigid end posts f2 which also project I upwardly from the seat when it is inverted.

Links G pivoted at one end to the bars d* of the spacing section of the bed bottom, have pin and slot or other suitable sliding connections at g with the posts f2, and the opposite ends of these links G have pin and slot or other suitable sliding and pivotal connections at y with the bars Z2 of the intermediate frame section. When folding the be'd bottom from its extended or bed-forming position, shown in Fig. l, the outer section is raised and the links Gr are' adapted to slide andlswing on the posts f2 and also at their connections with the intermediatev section, thus permitting -the adjacent end of the intermediate section to fall intothe seat frame as shown in Fig. '5, the intermediate section swinging on its hinged Aconnections f with the seat posts f. These connections permit the short or spacing Section d* to swing with theouter section'd to the substantially uprightposition shown in Fig. 5. The links Gr preventthe spacing section d4 from swinging inwardly beyond the upright position, but the outer Isection d is adapted to fold at its pivotal connections with the spacing -section d4 over on the intermediate section d2. The spacing sectional'i thus holds the adjacent edges of the intermediate and outer sections apart and lprovides ample room between them for the folded mattress D. After the outer section has been folded over on the intermediate section as eX- plained and as shown in Fig. 6, the seat B its normal or seat forming position, and

whenthe seat is thus returned to its normal position the supporting links for the inner bed-bottom section and the hinges between the latter and the intermediate section permit the inner section to fall into the stationary frame and the folded intermediate and oifter bed bottom sections to, fold over above tho inner section, as shown in Fig. 7. When thus folded, the hinges d5 between the inner and intermediate sections provide suicient room betweenl the hinged edges of these sections to accommodate the folded mattress and the outer end of the mattress and .the

the connections of the outer section to the intermediate section. The ends of the horizontal anges of the bars d4 also act as stops to prevent the spacing sectionfrom swinging beyond a substantially upright position when folding the bed bottom.

The bed bottom fabric is preferably connected to the` folding sides of the bed bottom frame by. the usual springsv which afford the necessary resilience for the bed bottom, and in order to prevent the strain, due to the pull of these springs and the weight of the occupant of the bed, from springing the folding sides of the frame inwardly, the bars d4 of the spacing section are connected by a rigid brace or bar H,

. which extends from side to side of the folding bed bottom frame beneath the fiexible fabric.

Legs I of any suitable sort may 'be employed for supporting the couch seat in its inverted position. The legs shown are pivoted in sockets on the ends of the seat adjacent to its free or rear edge and are adapted, when the vseat'is returned to its normal position, to swing down between the ends of the seat and the ends of the couch tothe position indicated in Fig. 7, so as to be hidden from view.

K represents folding legs for supporting the outer end of the outer bed bottom section. These legs are preferably rigidly connected by a cross bar 7c and are hinged or pivoted in any suitable manner at 7c to the en'd of the outer bed bottom section so as to swing down against said section when the section is swung upwardly in folding the bed bottom.v The legs K are provided with projecting latch bars L which, when the outer bed bottom section is folded over the intermediate section, are adapted to engage with `studs Z projecting from the ends of the intermediate section, to hold the outer and intermediate sections from relative movement when the couch seat is turned upwardly to its norma-l position.. As shown, the latch bars are provided with notches which the studs Z are adapted to enter, and the weight of the legs K tends to hold the latch bars in connection with the studs.- In opening the Vbed after the couch seat has been inverted,

thus partially unfolding the bed, the cross bar lo connecting the legs K is grasped to turn the outer bed bottom section over to its horizontal position, and the pulll onthe legs K, disengages -the latch bars L from the studs Z so as to release the outer section.

'Z' represents braces connecting the latch bars L to the legs for holding thelatch bars rigid.

M represents springs attached to the posts f on the couchseat and thefendsof the4 stationary couch frame for counterbalancing the Weight `ofthe seat and the bed bottom,

and assisting in the movement of the parts when .opening and closing the bed. Thesev springs or other suitable means for the purpose may be employed or not., as desired.v

By constructing and mounting the bed bottom as described, With the inner section movably supported by the stationary frame A-and `the other sections carried by the, couch seat, the seat can be hinged'to the front of the couch by ordinary hinges of an inexpensive kind, and 'hingesand fittings of special design and more expensive construc- -tion are avoided.- Simple pivotal connections are also used for connecting the sections of the bed bottom frame to each other and to the couch seat, and the parts are few .in

number and of-finexpensive construction.

For instance, but one pair of plain bar links is used in addition to the bar sections of the bed bottom, for permitting the described folding of the outer and intermediate sections and for rigidly supporting them'When the bed is' extended. Nevertheless, the

couch can be operated readily and with butI i little eXertionin converting it from sofa to4 ordinary-bed VWith a non-'folding spring botbed and viceversa, and when the bed bottom is extended, the ieXible spring bottom fabric issupported by itsframe from end'to end and sideto sideabove and clear of the couch seator other underlying parts o f the couch,

so that it will aford'the same comfort as the tom or bed springl- The b ed thus formed is I essentially more comfortable andV desirable than one which is formed in" part by anupholstered part of thecouch seat or back.`

I claimy as my invention:

' `l. Ina lsofa be'd, 'the combination of a.'

stationary frame, a `couch seat. Which4 is -hinged to said frame and is A'adapted to`\b\e inverted in front thereof, and a folding bed l bottom having a frame comprising con nected inner, outer` and intermediate sections, said intermediate section being nmount-- ed on theunderside Iof said couch seat and supported above the same When the seat i's; inverted, said inner lsection being movably mounted on said stationary frame and connected to said intermediate section by means which space said sections apart When theinverted in front thereof, and a folding bed bottom having a frame comprising connected 1nner, outer and mtermediateI sections arranged to fold With said outer section between said yintermediate and inner sections, said intermediate section being hinged to said inner section and .hinged to vsupports `vwhich rise from the. hinged side of said couch seat when the seat is inverted,.

a spacing section connecting said outer and intermediate sections, links connected to said spacing section and having sliding and swinging connections with said intermediate section and with supports on said couch seat,.movable supporting means connecting said inner section With the stationary frame,
