sore-BED.

Be -it known that I, Pirrna E. KBOEHLER,

'a citizen ofthe United States, residing lat l ITaperi'lille,A in` the county of Dupa e and State of Illinois, have invented aV So a-Bed,

o f which the/following is a specification.

My invention is an improvement in sofas or davenports, and the primary ob]ect of l xtheA sameis to ,provide a combination 'sofa andl bed of such construction that when the arts'are arranged in the form of a sofa' or avenport the device will have the usual appearance ofthis particular Style of furniture, and vwhen arranged in bed form a foldabl'e mattress which is normally concealed under the upholstered seat of the sofa or davenport will be brought into a horizontal position and firmly supported for use as Aa bed.

' With this primary object in View my lini jyentionf consists lin the combination with a sofa frame and v'its seat, of a folding mat- SpPPeredge of the front rail by means of the ltress and means, as levers and links, for r connecting4 the same to the sofa frame and 2.5.v

seat and or Supporting the latter, such con-- nectin means being so constructed and arrange as to operate the mattress and sup portwhen the seat is swung out of and into the frame; all as hereinafter fully described and specifically Set forth in the appended claims.

In the accompanying drawin s which form a part of this s ecifcation: Fig. 1 is an Iend View of a com ination sofa and bed constructed in accordance with my invention, the parts being arranged in bed forni and the near end ofthe sofa-frame removed.A Fig. 2 is a detail hereinafter referred to. Fig. 3 is. an end view, partly in section, showing the parts arranged to form a sofa or davenport. Fig. 4 is a similar view, the seat being raised in the operation of converting the sofa into a bed. Fig. 5 is a detail view of a pivot connection, hereinafter referred to.

Like numerals of reference indicate like parts inA al1 the gures of the drawings. y I n carrying out my present invention I employ a conventional form of sofa or davenport frame, comprising` the

end pieces

5, 5,'back6, and front rail 7, and in conrovide a suitably up- Specioation of Letters Patent. Appiioation file d :une s, 190e. serial No. 500,926.

hin es 9, so that said seat may be swung out of t e frame in converting the sofa into a bed, as hereinafter explained. The rear end of the seat is supported in the frame by Secured to and projecting from the inner'V sideA of the seat at each end thereof is 'a supporting-bar l2, reinforced by an inclined brace 13, (see Fig. 2), and tothe outer endsy of these supportingLbars is pivotally connected the center section 14 of a foldable mattress frame comprising three sections, to wit: the aforementioned center section 14, and

opposite end sections

15 and 16. The outer end of inattress-frame section 15 is connected to the seat by a supporting-link 17, which is of such lengt-h that when'the seat'S is swung. to its' position in front of the sofa frame said end lsection will be supported on a. line with the center section 14. The other end section, 16, of themattressframe is pivotally-connected to one member, as 18, vof, bell-crank levers 18, said bellcrank levers being pivoted to the inner sides of'the end pieces` 5 of the sofa-frame by means of pivot-pins 19 extending into said end pieces. These bellcrank Ilevers are adapted to support the mattress-frame section 16 at that end or side opposite its connection with the center section 14, and in order to Inechanicall operate said bellcrank levers to roper y raise and lower the section 16 as tie seat is manipulated the short member, 18", of each bell-crank lever is connected by a rod 2() to the inner end of said seat a short distance from the hinge.

' lVhen the seat is swunfr to the position in front of the sofa-frame the outer end there of is supported by means of legs 21, iv,- oted at each end of the seat and adapter to b e swung to a vertical or supporting position by means of links 22, each link being connected at one end to the Aprojecting end ofthe supporting-leg and at the other end tothe section 15 of the mattress-frame, the' latter connection being preferably by means ofthe same pivot, as 23, by which the supporting-link 17 is connected to said section.

This connecting-link 22 acts to swing the 'Supporting-leg to a supporting position and to a position alongside of the end of the seat below the upper edge thereof when the the mattress-frame is supported yat the centerl bythe supporting-bars 12, at the outer end by means of the supporting-links 17 extending from the supported seat 8and at the inner end by .means of the bell-crank levers 18; and thatwhen the seat is swung into the sofa-frame, as shown in Fig. 3, the

sections l

14, and 16 are'folded below the sofa-seat,

while the supporting legs 21 are swung alongside the ends of said seat so as to be concealed,`the inner portion of the seat being then supported by the arms 10. In this latter position of the parts the device assumes the character of an ordinary sofa or davenport. l

It will be noted that when the sectional mattress-frame is folded below the sofa-seat the center section 14 is disposed vertically immediately in the rear' of the front rail 7, with the

end sections.A

15 and 16 disposed horizontally one fabove the other leaving a space in which the bed clothing may be stored; also that the mattress-frame section 16 maintains a horiaontal position during the raising and lowering of the same in converting'the sofa into a bed, and vice versa,

and therefore the bedclothing may be folded and lplaced on this section before the seatis sw'un'g into the frame and the mattress-frame folded,\and such clothing will not be disturbed by the operationof the parts.

The pivotal connection between the bellcrank lever .18 and end piece of the sofaframe is'preferably by means Iof a plate 24, (see Fig. 5), which is attached to the end piece and providediwith an open-ended'slot into which the headed pivot-pin 19 engages. This connection is provided in order that the parts may be readily-assembled after beingshipped in knockdown form, and for the latter purpose I also purpose to connect the vfront rail 7 and back 6 of the sofafframe -to the end.- piecs I5 thereofby means of the usual form of bed fasteners. l

Having thus described my invention, what I claim as new and .desire to secure by Let ters-Patent, is

1. Ina sofa-bed, the combination with a sofa-frame and seat hinged to the front end thereof, of supporting-bars extending from- .the inner `side of the seat, a mattress-frame.

comprising a center section connected to said support1ng-bars and end sections pivotally Aconnected to the center section, links connecting one of the end sections to the seat, andlevers connecting the other end section to the sofa-frame.

2. In a sofa-bed, the combination with a 4sofa-frame and seat hinged to the front end thereof, of supporting-bars projecting from the inner side of the seat, a mattress-frame comprising a center section connected to said supporting-bars and end sections pivotally' erating-rods connected to said bell-crank levjers and to the seat. j y

3 In a sofa-bed, the combination with 'a sofa-frame and seat hinged to the front end thereof, of supporting-bars projecting from the inner side of the seat, `a mattress-frame comprising a center section connected to said supporting-bars andi end'sections pivotally connected to the center section, supportinglinks connecting one of the end'sections to the seat, `bell-cranlrlevers connecting the other end section to the ends of the sofaframe, and operating-rods connected to the bellcrank levers and to the seat near the hinges; together with supporting-legs pivoted to the ends of the seat, and'links connected to the-legs and to the adjoining maty seat and frontand rear sections foldably related to said intermediate section, and mechanism operative to automatically unfold the bedv sections and elevate the front and rear edges respectively of the front and rear bed sections in the operation of invertlng the seat. 1

In testimony whereof I have signed my name to this speciication'in the presence ot two subscribing witnesses.
