` To @ZZ whom it may concern.

Be .it known that I, ERIOJSODERGREN, of Brooklyn, 1n the county of Kings and State .e of New York, have inventeda new and useful Improved Sofa-Bed, of which the following isa full, clear, and exact description. l

My invention relatesgto an improved sofa bed, and has for its objects to provide a novel,

convenient device of thecharacter indicated,`

which will be of a compact construction, afford a receptacle at one end of the sofa,\and l provide a vertically adjustable spring bed within the frame of asofa or lounge, that is connected with the sofa seat so as` to be ele-` vated, when saidseat pieceis elevated,and thus removed from the top of the sofa frame, and be automatically depressed by a return of the seat piece to a horizontal plane.

To these ends my invention consists in the construction of parts, as is hereinafter described and claimed.

Reference is tobe had to the accompanying` drawings, forming a part of this specification,

in which similar figures of reference indicate e tional view, on the line 4-4 in Fig. 3. Fig. l

corresponding parts in all the views. i

Figure 1 is a broken plan-view of the improved device showing the sofa top removed from the frame.. Fig.`2 is a sectional side view on the line 2---2` in Figi, showing parts adjusted to form a sofa or lounge. Fig. 3` is a sectional side view on theline 2,-2 in Fig.

1, representing parts arranged to convert the sofa into a bed.` Fig. 4 is a transverse sec- 5 is an inverted plan view of the sofa seat piece at its lower end; and Fig. 6 is a transverse sectional view taken on the line f in Fig. 5. j

The mainframe for thesofa and ,bed,`con,h e sists of a box like structure l0, that is oblong and rectangular, having suitable dimensions l for eiiicient service, said frame being preferably supported on casters. At the headof the frame l0, a chamber or receptacle 10a, is

formed by the introduction of a transverse partition 10b, at a proper point, this chamber being convenient for the reception otjbed clothing. Within the main portion of the frame 10,a spring bottom framell, is loosely fitted, which consists of a light strong frame that will easily slide in the part 10, and has the wirewoven spring fabric 11a secured in tautcondition onitsupper surface. The

lengthof the spring bottom frame 11, is so proportioned that a suflicient space Will be afforded at each end of said frame for the `attachment thereto of bracket-frames and grooved pulleys 12,that are rotatably supported by these bracketframes, the latter be,

ing fixed one near each side of the frame 11, at each end. The grooved pulleys l2, engage their peripheries with the ribbed projections of the guide strips12, that are secured upon .the lowerV end wall and the partition` in the main box-shaped frame 10, at. points which will permit the free vertical reciprocation of the bed bottom frame.

The "frame 11 isgsustained and vertically adjusted in the main frame 10, by duplicate mechanism, one set being placedon each side ofthe framesmentioned, and located in spaces provided for their introduction and free movement, and as theparts are alike for each side, the description of one set will` answer for both.

In the space extending between the bed bottom frame and main frame before mentioned, e

. two pairs of similar link plates 13, are pivoted by one end ofl each plate upon the` side of the `outer or main frame l0 and theinner frame 11, near the ends of the same. The end portions of eachpair of link plates 13, that are adjacent have lapped contact and are pivoted together, and on the outersides of said lapped parts "the endspf aconnecting ybar 14, are jointed with the same rivets that pivot the link ends together. j

The lounge or sofa seat piece l5 provided `for the improved device,lcomprises a rectangular frame of -such relative dimensions as will adapt it to conformwith the upper edge ofthe main frame 10, whereon it is imposed nally slotted bracket blocks 16, provided for the jointed connection of the arms with the IDO seat frame, and these blocks which are affixed upon the lower edges of the frame, receive be- .connection between the parts mentioned.

The other extremities of the bent arms 16, are projected through the spaces formed between the sides of the main frame 10 and bed bottom frame 11, and are each pivotally connected to one end of a link bar 17, the opposite ends of these link bars being pivoted upon the sides of the connecting bars 14, near the longitudinal centers of the latter. When the seat piece 15, is adjusted as shown in Fig. 2, the bed bottom frame will be lowered within the main frame 10, and the links 13 together with their attachments,will be folded together as therein represented.

It will be seen that by the construction and arrangementof parts hereinbefore described, the rearward and upward movement of the seat piece, to dispose it in an upright position at the foot of the main frame 10, will cause the pairs of links 13, to be spread apart, and the bed bottom frame 11 to be correspondingly elevated, the degree of such a vertical movement being gaged by the relative proportion of the parts which effect it, so that the wire woven top 11, will lie about level with the upper edge of the main frame 10, when the seat piece 15is slightly inclined rearward from a vertical position, as represented in Fig. 3.

When the parts are adjusted as just described, a mattress 1S, may be laid upon the woven wire fabric 11, and a comfortable bed be thus afforded, to complete which the usual bed covering should be added.

At the head of the main frame 10, a lid 10c is hinged upon the top edge so as to adapt it to be swung up, and on the lid a pillow or or head rest 10d is formed or secured, which may be furnished with interior springs as a yielding foundation for upholstering, as indicated in Figs. 2 and 3, this head rest serving for the sofa and bed, as an elevated yielding support for the head of an occupant.

When the parts are to be arranged for service as a sofa having a single head piece, the seat frame is rocked into a horizontal position so as to dispose it upon the top edge of the mainframe 10, and to facilitate the swinging of the seat frame or piece, anti-friction rollers 19, are rotatably secured at the rear end of the main frame, and have their grooved peripheries engaged by the ribbed edges of trackstrips 19a, which are attached to the lower side of the seat piece near its rear end, this provision obviating wear and friction, when the heavy piece 15 is changed in adj ustment as before explained. j

In order to assist the movement of parts when the seat piece 15 is elevated, spiral springs 20, are placed at each end of the main frame 10, within it and between its bottom board and the bed bottom frame 11, these springs being compressed as shown in Fig. 2, when the device is adjusted to form a sofa, their energy being exerted to throw up the frame 11, when the seat piece 15, is erected into the position indicated in Fig. 3.

It is claimed for this device that it is c ompact and convenient, is readily convertible into a bed or sofa as occasion may require, and that when arranged to providea bed, the elevation of the woven wire bed bottom simultaneously effected withthe elevation ofthe sofa seat piece, will so remove the bed frame from the lioor of an apartment wherein the device is located, that a healthy and comfortable bed will be provided, the change of adjustment to produce a bed or sofa being quickly effected without the use of tools.

In the chambers, or living rooms of small houses or flats', room space is contracted in area, and an open bed, or ordinary folding bed cannot be conveniently used, nor lcan a bed lounge that folds outwardly at one side, as the increased width of the bed thus provided may require the removal of other essential pieces of furniture from the room. This 1mproveinent is specially advantageous for use in such residences, as it affords a neat, commodious sofa for seating or reclining purposes during the day, and a readily convertible single bed, that does not take up more floor space than the sofa, the vertical rocking movement of the seat piece 15, at the foot of the sofa frame serving to elevate the bed frame, and as the seat frame may rest against a wall of the room, no available space is taken up by it when it is elevated into a vertical position.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination, with the main frame of a sofa or lounge, of a seat piece pivotally connected thereto to rock or swing on an axis that has movement longitudinally of the main frame and is arranged transversely of the sofa frame, near the foot end thereof, so that the seat piece can be brought into an upright position at the foot end of the sofa, substantially as described.

2. The combination, with the main frame of a sofa or lounge, of a bed bottom frame having vertical sliding movement in the sofa frame, a seat piece having a pivotal connection with the sofa frame at one end thereof to swing in a plane extending longitudinally of the sofa frame, the pivot of the seat having movement longitudinally of the main frame, and an operative connection between the seat piece and the bed bottom frame, lsubstantially as and for the purpose set forth.

3. The combination, with the main frame of ing longitudinally of thesofa frame, to bring the seat piece into an upright position with p its end portion resting against thatof the sofa frame, substantially as described.

4. The combination, with themainzra'me` having a partition to form two compartments therein, of a bed bottom frame having vertical sliding movement in one of the said compartments, links having pivotal connections ro with the main frame and the bed bottom frame respectively, rods connecting the links, a seat l piece having a pivotal connection with the main frame, and an operative connection berods,` subtween the seat piece and the `said stantially as described.
