APPLIUATION FILED JUNE 24. 191,0.

2. mL E L wn S S m., E D un un 2 To all whom it may concern: Be it known that I, RUDOLPH COOPER- sarrrri, a citizen of .the United States, and a resident of the city of St. Louis and State of Missouri, have invented a new and useful 'Improvement in Sofa-Bedsteads, of which "the following is a specification.

Thisinventionorelates to sofa-bedsteads.

- Itfhas for its principal objects to produce.; a convertible sofa and bedstead of simple and compact-construction which is light and` form part of this specificationan wherein..

*like* symbols refer' .to like parts Wherever `evoccur', Figure 1 is an endv elevation l1" "one of theend members ofthe sofa 25 f'main frame removed; cFig. 2 is a similar "vietril showingv the device converted into a be'ds'tead; :F ig. 3 is a fra mentary view, lpartij/ 'in section and part y in elevation, vowin a pivot andbearing for the reversible-section .of the frame; Fig. 4 is a section on the line '4s-4 of Fig. 3and Figs. 5 and G are fragmentary views, on an enlarged scale, v"showing" thev action of the supporting legs 'for the 'reversible frame. Themain or body frame ofthe sofa com- Aprises; end members 1 and a stationary back to `which the endime'mb'ers are connected. Abase board 3 connects the lower front portion of the'end members 1. As shown inv the 40 drawings, the end members 1 are inthe form ofV closed panels, but obviously the same may' be made as open frames; and, in so" far as the general arrangement of the `main `frame of the sofa is concernechit may `be of an desirable construction.

I An u'' olstered cushion or seat Il is mounted on t e upper side of a reversible pivotal frame 5. The front of the frame 5 is pref` erably.closed by a covering 6 which .isa con- .50"tinuati on-of the covering material of the seat 4'. The'frame is -a box'frame, triangular in transverse sectmn. That 1s, 1t comprises vtriangularl end frames or members which are rigidly connected by suitable longitudinal members (not shown), and suit- 4i serramenti);

the frame laretp'rovi-ded' with outwardly extending trunnio's7 which are pivotally mounted in box'castings 8 secured to the inner sides of the end members 1 near the .front edges thereof. The end members are normally supported at their inner corners on brackets 9 wliichare secured to the inner faces of the end members 1 -Extensions 10" at I:the lower corners of the triangular end members ofthe frame 5 are pivotally attached tothe corner extensions 11 of triangular end members of a secondary frame 12. A mattress 13, is mounted on the adjacent inclined sides of the two coperati'ng frames 5, .12; ThisI mattress is preferably a continuous' 'flexible one vso that it will readily lfold at .the breaking 'point between the two franies=5,"12. vThe second'ary frame Ais supported a't'its lowerinost corners by casterwheels 14' or rollei'sivhichrest 'upon the floor. The triangular-end members 'of the [secondary frame' `12 'are so proportioned with respect to those 'of the reversible frame 5, that when said-reversible frame is swung ably braced. `The 4vertical end members ofl i over on its pivotsl 7 until its 'normally 'inf' clined side onl .which the mattress' 13 is mounted assunfesla horizontal position,` shown in Fig.2', the=normally inclined side of the secondary/frame on which themattress 13 is `-mounte'd also assumes hori! yzontal. position inthe same plane. ln this opened position o'f'the two frames, the re"j -vers'ible frameis"supportednear its outeredge by legs or sumoorts 15v which are pivot? ally mounted'on'A the opposite ,ends of the frame.4 ireferablvfsaid-legs each have a longitudinal slot lftherein which slidjlblfgT fits a headed studi 17 projecting 'from fthe outer side ofthe frame member; Crlhe legs ating studs are so arranged, that when the stud 17 is at the'bottor'n. of the sl0t,`1(, the stud 19 also restson the bottom of the notch 1,8. By this. anngeinent,` the legs 15` are held against accidental collapse, when the parts are 1n tlieposltion shown 1n Fig; 2.

15 also have notches-18 vinl their ends so as to i When the fran'les are open as shown in Fig. 2, the pivotal connection between the parts 10 and 1l o-i,E the respectivo tramos 5,

12 is nearly. in' Vertical alincmont with the axis of the pivot-stmlsol tl'u'nnions 7; and,

tionate leverage of the device is such that a great weight can be sustained at or near the als said pivot points between the parts 10 and 11A without tilting the reversible frame.

To open the device to make it into a bedstead and close the same back intoV .its normal condition as a sofa, the reversible frame can be readily swun on its pivots and the secondary frame Wil accommodate itself to such movement owing to its pivotal connection with the reversible frame and its'arrangement of supporting rollers 14 which roll on the floor.

Obviously the device admits of c0nsiderable modification Without departing from my invention. Therefore, I do not Wish to be limited to the specific construction and arrangement shown.

What I claim is:

1. A convertible sofa-bedstead comprising a main frame, areversible triangular frame pivotally'mounted on said' main frame, and a secondary triangular frame' -pivotally attached to said reversible frame,

said reversible frame being arranged and adapted to provide a support for the sofa seat in one of its positions and a supportA for the bed mattress in its other position.I and said secondary frame being arranged and adapted to accommodate itself to; the movementof said reversible frame and'form a. support'for the bed mattress in the same plane as the reversible frame.

2. A sofa-bedstead comprising a reversible frame which is triangular in transverse Section, said frame being pivoted at its opiposit'e ends, a seat mounted on one side of said reversible frame and a mattress mounted on the side of said frame opposite to that on which the seat is mounted-,and a secondary frame pivotally connected to said first. mentioned frame, said Secondary frame being also ltriangular in transverse section,

said secondary frame being so proportioned with iiespect to said first' mentioned frame,

that when said first mentioned frame is re.

versed and its side on which the mattress is mounted is brought into a. horizontal plane,

one side of the secondary frame also assumes a horizontal position in the same plane, and when said first mentioned frame is in the position with the side on which the seatV is mounted in a horizontal plane, said secondary frame is folded under' said first. mentioned frame, and a mattress on the side of said secondary frame which cooperates with the mattress side of said first mentioned frame.

3. A sofa-bedstead comprising a reversi ble frame which is triangular in transverse section, said frame being pivotally mounted at its oppositeends near one of its sides, one

v tioned frame, said secondary fi'a-me being side of said secondary frame being .normally in substantially parallel relation to the inclined side of said first mentioned frame and having, a mattress thereon, said 'two mentioned frames being so proportioned with respect to each other, that when the first mentioned frame is swung over on its pivots and its normally inclined mattress side is moved into -horizontal position, the

second-ary frame is also moved so that its mattress side is in the same plane horizontally as the mattress side of said first nientioned frame.
