Application filed January 26, 1915.: Serial No. 4,4:65.

To all whom it may concern Be it known that I, sonmAu-Us'mvron, a subject of the Czar of Russia, residing at San Francisco, in the county of San Francisco and State of California, have invented new and useful Improvements in Bed-Davenports, of whichthe following is a specifica- This invention relates to improvements in' davenport-beds, and more particularly to, that class thereof wherein the bed or mattress-support is composed of two foldable sections disposed lengthwise the davenportframe, said sections, together with the bedding being adapted to fold withinthe davenport-frame and below the seat -and to be unfolded to form frame.

-Among the objects of the invention are to providea bed of this character wherein the greatest length of the bed is at a right angle to the davenport-frame,'so that the occupant of the bed will beableto repose with his .space; and

head toward the back of the daven-port; to provide a comparatively simple and inexpensive mechanism for. supporting in a stable manner and operating the moving parts; and to so arrange the same when one bedsection is unfolded that it'and its companion are substantially balanced upon a common center, thereby reducin the labor involved both in opening and c osing the bed.

Other objects and advantages of the invention will hereinafter appear, and the novel features thereof :will be particularly pointed out in the appended claims.

' Referring to the drawings:

Figure 1 is aview partly inelevation and partly in section ofa davenport embodyin my invention, the bed being shown folde and out of use within the davenport-frame;

Fig. 2 is a similar view, the bed being illustrated as partly opened;

" Fig. 3 is a fragmentary view in perspec-- tive hereinafter referred to;

Fig. 4 is a view similar to Figs. 1 and 2, the bedbeing illustrated as unfolded and in operative position; Y

Fig. 5 is a horizontal sectional view through the davenport frame above the open bed, the parts being shown in the same position as in Fig. 4 and broken, away to save Fig. 6 is a detail enlarged illustrating a oint heremafter described.

a bed in front of said Similar numerals of reference indicate similar parts in all the figures of the draw- 'lngs.

I employ the .conventional form of davenport-frame, and, as illustrated, the same consists of the opposite ends 3, 3, connected by' 1 pose of receiving the back when occupying its retracted, position, all as clearly shown in Figs. 2 and 4. For the purpose of automatically retracting the back, when the same is released from the seat, in a manner hereinafter explained, one or more retractingandlbe seated in sockets formed in the backwa The seat 14, is provided on its upper side with the usual upholstery 15, and each of its front corners has secured thereto, as at 18, depending rigid standards 16, prefer ably angular in cross-section. Pivoted as at springs 10 may be connected to the'back.

19 to the opposite ends of the seat and near 7 its rear edge, are legs 21,, the same being disposed oppositely to the standards 16.:' These legs are extended above their pivots 19 forming extensions 20, and they latter are at their extremities pivoted as at 23,t0 short standards '24, bolted to the opposite sides 'and at intermediate points of the foot-see tion 25 of the folding-bed or mattress-sup- Port.

This section.- 25 of the bed-frame exceeds inwidth the sofa-seat, the rear edge of the their ends, pivoted, as at 27, to the ends of the side-bars of the foot-section 25..

Below the latter section, and correspond ing in proportions thereto, is the main or head-section 30. The side-bars of this sec tion are pivoted, as at 29, to the lower ends of the spacing-section 17, immediately above and in rear of the cross-piece or bar 5, of the sofa-frame, and at their rear ends, said bars are pivoted, as at at, to the'corresponding ends of a pair of rigid supporting-links 43, the front ends of the latter beirn pivoted to the ends 3, near their bases. winging upward and forward on the pivots 42, it will be seen'the head-section 30'of the bed will be raised, and, ofcourse, a reverse movement of the links will have the effect of lowering the section to the position in which it is shown in Figs. 1 and 2.

Pivoted upon a rod 32, near each of the ends 3, at their front edges and immediately above the cross-bar 5 and the pivots29 between the head-section 30 and thespacing section 16, are triangular-shaped double bell-crank levers 36. Each of the double bell-crank levers 36, has its'rear branch 34, pivoted at 35, to one of the side-bars of the head-section 30, at an intermediate point of said side-bar, and its forward branch pivoted, as at 37, to the rear end of the rear section 38,0f a jointed link 39, the front section 41, of the link, being pivoted to the bolt 27, serving as a pivoting means between the foot-section 25 and the spacing-section 17. The joint between the link-sections 38 and 4-1, is formed by the pivot 40, so that said jointed link is capable of folding (as in Fig. 1) and extending (as in; Figs. 2'

and 4).

Upon each of the bolts 27, which, as before stated, serve as. means for pivot: ing the side-bars of the foot-section 25 with the ends of .the spacing-section. 17, there may be coiled a spring 45, the terminals of which extend at opposite sides of the coil and bear upon the horizontal flanges of both the side-bars of the section 25 and the spacing-section 17, the tendency of the springs being to maintain these sections in horizontal alinenient. When, therefore, these parts are folded so as to be disposed at an angle to each other, such posi+ i supported by the spacing-section 17, (which assumes a vertical position,) and at its rear end by a transverse sill orledgedil, secured to the back-wall. cf the davenport t raeeeco a bed, the springcatch 11 is disconnected between the seat and movable back '8, the spring 10 acting to draw the back rearwardly, as heretofore explained after which. the seat is automatically raised or thrown upwardly by the springs 45 to a position somewhere between the positions shown in Figs. 1 and The seat may be readily grasped when thus raised and manually and successively moved to the positions shown in Figs. 2 and 4:. It will be observed that upon elevating the seat the foot-section 25 of the bed automatically separates from the seat (see Fig. 2), the legsassuming a position at a right-angle to the frame so as to support the same when lowered to operative position, as shown in Fig. 4. As the seat and footsections continue their'lowering movement (from the position shown in Fig. 2 to that shown in Fi g. l), the links 38 and 39 serve to swing the triangular shaped bell-cranks forwardly upon rod 32, said bell-cranks, in turn, lifting the head-section 30 and causing it to assume a horizontal position in the same plane as the foot and spacing sections, so

It will be understood, of course, that any desired construction of mattress supporting wire fabric maybe employed. such forming no part of my invention. In the present instance I have shown the sides and ends of the fabric connected to the frame-bars of the bed-frame by means of coiled springs 31, but these may be omitted and the fabric connected directly-to such bars. 9 v

In operation, after the seat has been released from its locking engagement with the back and has been slightly elevated by the expansion of the springs 45, the back edge of the seat. is grasped by the operator, in the manner heretofore described. and elevated to the position in which it is shown in Fig. 2. This movement of the seat permits the foot-section to separate from it, the legs automatically assuming an angular position with relation to the seat and footsection and the links 38 and 39 alining with each other and being therefore in position to evatetheina r r h adee t ea. Thus far aaeaeoo the latter section has not been afi 'ected by the opening of the seat and foot-se'ctionJ When, however, the links 38 and 39 aline, further movement of the seat and the footsection causes said links to elevate or reek being by reason of the fact that when the seat and foot-section have been elevated approximately to the position in which they are shown in Fig. 2, these parts are in front or at the opposite sides of the pivots 32 of the hell-cranks. So it is also in the operation of closing the bed. In this latter operation, the operator grasps the outer end of the foot-section and elevates it, when thehead-section begins to lower and the bellcranks swing or rock to the rear, the. combined weight of the two serving to counterbalance the weight of the seat and foot-sections to some extent. Thus it will be seen that the bed may be operated with very slight manual exertion; en the bed is folded or closed the rear edge of the foot section rests upon the sill 49, and by reason of the link cOnnection between the foot-section and the seat, the latter collapses upon the former and 'is supported thereby. In thus collapsing, itwill be seen that the supporting-leg 21 assumes a positionparallel to the foot-section, so that both it. and the footsection extend rearwardly under and lie partly back of the back of the davenport when the latter has been drawn out against the tendency of the springs 10 so that its lower edge may again engage with the catch 11.

The bell-crank levers maybe given shapes other than as shown, the only ess ent ialbeing that substantially the pivotal relations ,shown be preserved;
