To all whom it may concern:

,Be it known that 1, Jones J. Gnunnrnin,

JR, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Sofa-Beds, of which the following is a full, clear and exact description.

Fhe invention relates to sofa beds.

One object. of the invention is to provide an improved construction for a folding sofa bed comprising a section of the bed which is folded into position at the back of the sofa, a section fixed to an overturning seat and a plurality of sections below the seat when the bed is closed.

A further object of the invention is to provide an improved sofa bed composed of adapted to be folded to a position at the back of' the sofa and is provided with a sofa back pivoted thereto and is foldable to a pendant position at the front of the bed when the lat ter is in operative position.

A further object of the invention is to provide an improved sofa bed which may be easily operated from closed to open position and vice versa.

Other objects of the invention will from the detailed description.

The invention consists in the several novel features hereinafter set forth and more particularly defined by claims at the conclusion hereof.

In the drawings: Figure 1 is a vertical transverse section of a sofa-bed embodying the invention, the bed being closed. Fig. 2 is a detail perspective of the locking joint betwe'enthe foot-section of the bed and the section fixed to the overturning seat, the parts being shown in position assumed when the bed isclosed. Fig. 3 is a perspective of the-same, the parts being shown in position assumed when the bed is open and the lock is operative. Fig. 4 is a vertical transverse section showing the parts in position assumed during a folding operation. Fig. 5 is l a vertical transverse section, showing the bed open. Fig. 6 is a partial plan of the parts in position shown in Fig. 5. Fig. 7 is a side elevation of a portion of the :bed and the appear sofa back whenthe bed is cldsed. Fi. 8 is a rear view of the parts shown in Fig.

Fi 9 is a section taken on line 9-4) of Fig. I

Fig. 10 is a detail of one of the plates of the compound pivotal connection between the bed and the sofa frame.

Thesofa frame coprises members at the sides thereof respectively, each member comprising a side 1%, a front post 15, a rear post f6 and an arm rest 17. Said members'are rigidly cross-connected by a board 18 at the back and top of said members and a fe 19. seat frame carrying a seat 24: and comprising sides 20 and longitudinal connecting members 21, 22 and 23, is pivotally.

mounted in the sofa frame, as hereinafter set forth, and 1s adapted to be overturned.

A compound pivotal connection is provided between the seat-frame and the sofa frame of the type more particularly set forth in an application filed by me Sept. 13, 1916, Serial No. 119,817, whereby the seat will successively swing about different fulcra to attain the advantages more fully pointed out in said application. In the present invention, this connection comprises a pair of like plates 25 fixedly secured to the sides 14 of the sofa frame respectively. Each plate guides a lower pivot stud 26 and an upper stud 2'? (Fig. 1), both fixed to a bar 28. Bars 28 are secured to the sides 20 of the seat frame respectively. Each plate 25 is provided with an arcuate slot '29 in-which one of the studs] 27 moves, while the seat frame is swinging around studs26 as a fulcrum and an arcuate slot 30 in which one of the studs 26 moves when the studs 27 are positioned at the lower ends of slots 29 and are acting as a fulcrum for the seat. As av result of this construction of these plates, the

seat and parts connected thereto will be to be in operative position, initial forward. and upward swin of the seat will cause thestuds 27 to move orwardly and downwardly in the slots 29 and until studs 27 resfiin the lower ends thereof and thereafter continued withgig . forward and downward swing of the seat will cause the studs 26 to move upwardly in the slots 30 until arrested by the upper ends thereof. 4 In the present invention, these; plates 25 are cut away or open between the; upper ends of the arcuate slots 29 and 30.

1 The plates are provided with overhanging hanging portions 31, t V manipulated to disconnect it from the studs portions 31 to lock the studs against upward movement when the seat is either in its operative or completely overturned position,-

B formin the plate 0 on between the over-' y g" li s t anbeesily e ea c a as well as to permit placement thereof in position.

- The bed is composed of a section 35, which is rigidly secured to the underside of the seat frame, so that when the seat is overturned,

said member will be disposed above the seat,

a foot section 37, which is pivoted to sec-, tion 35 at 37', a short section 36, pivoted to section 35 at-36','and a head section 33 pivotally connected.' to the member 36. Each of these members comprises a bar at each side of the bed. The sides of the head-member 33 are connected by a cross or head rail 38 and the sides of member 37 are connected by a cross or foot rail 39. A tubular bar 35 additionally secures section 35 to the seat frame. The bed frame is usually provided with a spring bottom (not shown) as well understood in the art and when the seat is overturned and the bed is inoperative position, the sections of the bed frame will be extended in a horizontal lane as illustrated in Fig. 5. When the be is not in use, the

foot section 37. assumes a nearly upright 'osition to the rear of the seat and the sofa ack 41; section 35 which is fixed to the seat will be disposed thereunder; short-section 36 will extend verticall and downwardly from the front portion 0 the seat and the headsection 33 will extend rearwardly and horizontally from the lower end of section 36.

A. sofaback 41 is pivotally connected by hinges 42 to the rail 39 and comprlses a frame 43 which forms a. support for a back-cushion. The urpose of connecting the sofa back to ,the .oldable bed frame 18 to utilize said back as means for 9 crating the foot section in folding and un oldin the bed and as means for operating le or supporting the bed when it is 0 en. lthebed is open, the sofa back W1 1 be disposed below the foot of the bed and the legs operated by the sofa back will support the foot of the bed when it is open, asillustrated in Fig. 5. At

a each side of the bed'there is aleg 44, which is pivoted as at 45 to a plate 46, which issecured to .one endof the sofa back and a luck 47 which is pivoted, as at 48,- to a leg 44 and to the bed section 37, as at 49. Each plate 46 is provided with an arcuate slot 56 for the travel of stud 51 on one of the legs clothes.

-44 to limit the pivotal movement of said member. These slots are and formed so that when the jointed leg is in operative position (Fig. 5), they will hold legs 44 against movement inthat direction in which the load tends to move it. When the thereafter back 41 will cause the bed-section 37 to move in unison with said back.

A foot board 55 is pivoted, as at 56, to lugs 57 on the foot rail 39. This foot board is normally and yieldingly held in folded position across the back of bed-section 37 (Fig.

7) by springs 58, and the movement of this foot board is utilized to operate locking plates 59 which are slidably connected to the side bars of said section respectively by stud-and-slot-connections 60 and are connected to the foot-board by links 61, to lock sections 37 and 35 in alined relation.

Springs 58 are connected to bed-section 37 and to the foot board 55, as at 58', so that the springs will cross the dead center, so

that they will serve to yieldingly hold the foot board in either of its alternative'positions. When the foot board is lowered, it will press against the mattress and serve to hold it on the bed which is necessary when the bed is closed, because section 37 and that portion of the mattress which is on it are then vertically disposed. Springs 68 are connected to bed-section 33, as at 69, and to the sofa frame, as at 70, and serve'to hold up the head-section of the bed when the latter is closed, as shown in Fig. 1 and to hold said member downward and alined with the remaining sections of the bed when the latter is open, as shown in Fig. 5, the comics tior for these springs being disposed so that they will operate in this manner. These springs, while the seat is being overturned,

exert a pull upon the head section 33 in such direction that they sections 33 and 36 so that no separate shift of these sections will be necessary. in 010s ing the bed, these springs 68 retard the move mentof Sections 33, 36, so they will pass into position shown in Fig. 1, without special operation. The pivotal connections between sections 35 and 36 and between sections 36 a'nd 33 are suitably formed to limit'relative' closmg movement to the position shown, to

leave a-space for the mattress and bed e pivotal connections will tend to aline the,
