. struction and which possesses a high degree g comfort when used either as a sofa or a A further object of the invention is to provide a` folding bed. in 'which the mattress framesor supports are independently movable in ne position and comointly movable in anothenposition.

. The invention possesses other advantageous features, some of which, with the fore y going, will be set forth at length in the following description where I shall outline in full that form of the invention which I have Selected for illustration inthe drawings accompanying and forming (part of the present specification'. In said ravvings, I have shown one specific form of. my generic in "ventiombut it is to be understood that I do not limit myself to such form because my invention mov be embodied in a multiplicity of forms, een; being a species of my said invention.' It is also to be'nnderstood that by the claims succeeding the description of my invention, I desire to cover the invention in whatever form it may beembodied. f Referring to said drawings, `Figure l 'is a i vertical section of the `bed in the folded position, the bed springs being removed to bet* ter disclose Athe construction.

Fig. le is a detail of' the end of the bed showing the foot rail raised. Fig. '15 is a similar view showing the foot rail in its folded position.

Fig. 1G is a detail. of a portion of the bed frame in the two-fold bed.

In the drawings I have shown a one-fold bed and a twofold bed, the construction of the two-fold bed being similar tothat of the one-fold be'd with the exceptonof the additions necessary to effect the operation of the two-fold bed. I shall first describe the onefold bed and then the additional features of the two-fold bed.

'When the invention is embodied in a davenport, the device consists of a suitable stationary body comprising a base-2, the sides 3 and the back f1 which may or may not be upholstered desired. The back is stationary and is arranged at the upper por-l tion of the body only, allowing-the space Within the hodv and below the back to-bo used for receiving the folded bed. One of' the objects of this invention is to so arrange the bed frames, that when they are folded within the body, sulticicnt space' is provided for an upholstered mattress, and so that the seat is not too high to` be comfortable. Ar`- ranged in the body are two Amattress frames 5 and G, the, upper fra-me 6 being provided' on its upper side when folded with a seat 7, preferablv upholstered. Secured to the under side of frame 6 are a plurality of coil springs 8 which are connected together at their free ends by a fiexible 'metallic structure 9, producing a springjmattress Secured to the upper side of frame 5 are a Fig. l1 is a vertical i so other, the frame is turned over, so that when unfolded, the mattress formed 'by the springs 8 lies on the upper A'side of the frame and the seat 7 lies below the frame. thel frames iand (3 are' in the folded or superposed position, sufficient space is left between the structures 9 and 13 to accommodate a folded upholstered mattress 11, and the upper frame is vsupported at its inner end by stops 15 secured to the sides 3.

Means arey provided whereby the bed may be easily unfolded, the weight ot' the upper frame serving during part of its movement to raise or assist-'in raising the lower frame to its operative level. 1n order that the fdlded bed may li'e as-closc to the Iloor as is possible, the lower frame is movable from an elevated position when in use as a bed, to a depressed position when folded. In the opening or unfolding movement of the bed,

the upper frame is movable independently ,edge of the frame. The plate 16 is provided with a slot 19 concentric with the pivot 1'8 and disposed in this slot isa pin 21 which is secured to .the upper frame. The slot, in the present construction, lsubtends a'n angle of 90 degrees, permitting the upper frame to be moved 4trom-the position shown in Fig-1 to the position shown in Fig. 3, without producing any movement of the lower frame 5.

Fixed tothe pivot 18 (Fig. 13) which is fixed to the-'plate 16 is a strong coiled leaf spring 22, the free end otwhich presses against the pin 21 and assists in raising the upper frame 6 from its horizontal. folded position. A' disk 221 secured to the end of the pin insures engagement between the pin and the spring. v

The lower frame 5 is supported at the opposite ends on links v24-g2fi, which are pivoted to the side' or other stationar)vv part ot the structure, the links heingsimilarl;7 disposed so that the frame remains horizontal as it is moved. Connected to the pivot between the link 25 andthe frame is a link 26 which ispivoted-at its other end to the plate 16. in such position that as the plate is luovcd about its pivot 17. the link fis mo` ed to a. substantially vertical position. T n order to accomplish this movement and 'to prevent the links and parts from binding, the rear end of the frame 5 is-lifted by the link 27, which vis pivote'd at.

lV hen one end' to the link pin at the rear end of the frame and at the othervend to the plate 16.

The link 27 is provided) with a slot 28 in which the link pin on the frame engages, so that as the platelt is moved, the llnk 27 is raised above the fixed pivot of the link 24 before it exerts its raising effort on the frame.

The lower frame in raising swings about the fixed link pivots and sweeps forward and upward in van are, so that in its raised position it extends out over the base board 29, and the inner edge of thc frame swings forward and clears the back 4. lVhen in the l unfolded position the frames 5 and 6 abut against each, other and are alined, and the mattress surfaces 9 and 134 are alined.

The upper or folding frame, is supported at its outer end, when unfolded, by legs .31 which are pivoted to the frame in such manner that they are substantially rigid when in contact with the floor. The legs are slotted at their upper ends and engage pins 32 on the frame. Secured to the frame above the pin 32 Aarc two stops A33 between which the upperend of' the leg slides-and the stops prevent the leg from`.mo'ving about the pin when the leg is in contact with the floor, and'one of the. stopshol-ds the leg parbackward and assists in raising the upper frame lfrom' its unfolded horizontal' position. In order to'prcvent the upholstery 36 from folding up -and getting caught hetwecn the two frames when they are unfold- Aed, I provide means for pushing the upholstery outward and away from the frames. This means consists of a projection 3T on lcae-h plate 16 and a w'ire or rod 3S connecting the projections.

In Figs. 8 to'12 inclusive I have shown the invention as'applicd to a. two-fold bed. In this construction. instead of employing the coil springr mattress. as inthe prior construction. l employ a linked metallic structure 40.which is supported h v coiled springs 41 .attached tothe. frames. The construetion of the lower frame 5 remains substantially as before, with ,the exception that the `links` 2l and 25 vare made'longer, whereby the frame 5' is raised to a greater height. Se cured to cach ,side rail of the frame (i, by suitablev supports 42, arc hars 43 which, when the bed is unfolded,` arealincd with ment.l

the side rail 'Lof the frame 5, forminga continuation tti reofand to which the metallicl fabric 40 is attached. Secured to the ends of the side rails ofthe frame 5 are blocks 44 which project from the side railson the under side and form seats and supports for the rails 43, insuring their alinement with the side rails of frame 5. I"

Attached to the rails 43 at their outer ends is the folding frame 45 whi lh is foldable from `a positlon ofsuperpos tion with relation to therails 43 to a )osltion of alineends is a segmental gear 46, which is engaged by `a similar segmental gear 47 secured to the end of the side yrail or frame 45. Passing through tle center of each segmental gear is a pin and the pins are connected,

by the links 4E1 whereby the gears are held in mesh. Bv employing this form of connection, the fabric 40 is pulled taut as the frame' 45 is unfolded. When the frames 43 and 45 are alined, the link 48 lies above the level of the fabric 40, so that the tension of the fabric supporting springs holds the l frame 45 from folding backward.

Pivoted to the frame 45 at-f its outer end are the legs 5l upon which the outer end of the frame is supported.` Attachedto each leg 51 and to the frame 45 at a point adjacent the leg pivot 52 is a coiled spring 53. The points of attachment of the spring to the leg and to the frame are such, that as the legismoved from one positionto the'other, the spring moves past the pivot 52, thereby serving tc hold the leg either in its folded or operative position.` The spring 54, secured to the piyotfed foot frame 55 is similarly arranged, so 'that it operates .to hold'the foot board vertically, as shown in Fig. 14,

Y or operates topress it against the mattress,

in which position it operates as a clamp, as shown in Fig. 15. VA stop 56 secured to the frame 45 rests against the frame 5, when the bed is folded and supports the inner ends of frames 45 and 6.

Means cre provided for securing the frame 45 and the frame 43 together, so that they may be readily folded as one piece. Secured to each leg 51 is an extension 57, which when lthe frame 45`is superposed on frame 43 engages under a pin 58 on rail 43 when the leg is moved into parallelism with the frame 45. This locks the frame 45 to the rails 43,-so that the frame may not move relatively to the rails. The legs 51 on opposite sides of the bed are preferabl Iconnected together by a rod 59, and when 1t is desired to unfold the frame 45, the rod 59 is pulled, causing the legs to swing about their pivots and thereby ul'llatching the locking means, so that the frame 45 may be li ted over. i

I claim:
