JACOB LOEBIG, OF CHICAGO, ILLINOIS.

SOFA-BED.

' SPECIFICATION forming part of Letters Patent No. 321,305, dated June 30, 1885; Application led September 18, 1584. (No model.)

To all whom 15 may concern:

Ile itknown that I, JACOB LOEBIG, a citizen of the United States of America, residing at Chicago, inthe county of Cook and State of Illinois, have invented certain new and useful Improvements in Sofa-Beds; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

My invention has reference to a combined soi-bedstead; and the same consists in the improved construction and combination of the parts, hereinafter fully described and explained, whereby the structure is so arranged that the soia-sections of the same, when unfolded in a horizontal position to be used as a bed, will present upon their upper sides a continuous spring bed-bottom consisting of a scries of springs and cords arranged as described hereinafter, and when the said sections are arranged so as to present a sofa opposite faces of two of said sections will be brought into position to present the cushionsurface they are provided with for proper use.

In the accompanying drawings, forming part of this specication, Figure l is aperspective view showing the structure arranged as a bedstead. Fig. 2 is a central sectional elevation of the improvement adjusted as a sofa, and Fig. 3 is a detail sectional view.

The structure consists, primarily, of three sections, A, B, and C, the sections B C of which are hinged to the central section, A, as indicated most clearly in Fig. l, by means of hinge devices c c". The middle section, A, is provided with side sections, D, which, when the sections occupy the position illustrated in Fig. 2, form the side Varms of the sofa. The hinge devices c are so arranged and located as to permit the section A to be turned and folded upon the section B in a superposed position, as illustrated in Fig. 2, the hinge devices c being so located and arranged as to permit the section C to fold in a contrary direction, so as to bear against the face of the rear bar, b, of each side B, and thereby forni the back of the sofa. The said backsection is provided at each side with a bar, E, which isv provided with a recess, c, into which projects the end of a cross-rod, F, connecting said bars E together and carrying at each end in said re- 5 cesses a cam, f. The said recess c is an open recess, but is normally closed for the major portion of its length by a longitudinal block, Cr, pivotally secured near one end of the recesses by means of a pin, "g. The. open portion of the recess formed at the end of the block is partly covered by means of a plate, 7L, secured on the face of each barE. A spring, H, is secured at its rear end in a recess, i, in each side D, so as to have a limited play therein and 6 permit its free lip end j to project beyond the face of the bar b of said side. A coiled spring, L', located in the lower portion of the recess c, is connected both to the canif therein and a pin, Z, embedded in the bar E. An opening is located in the rear portion ot' each bar E and communicates with the recess c near the pivoted end ofthe block G therein, and thesaid opening is covered by a plate, m, provided with a vertical slot, through which plays a pin, a, having a knob on its outer side to facilitate the manipulation, and connected at its inner end by a cord or rod, o, to the cani j" below. The transverse bars p of the sections A C are connect-ed together by a series of textile straps, 8 g, which latter are connected together by a second series of straps, 1 1', which are arranged parallel with the bars p, and are riveted to the straps q Where they intersect the same. A

vertical coiled spring is secured at each of 8 said intersecting portions, as indicated most clearly in Fig. 1, and the said springs are properly based and supported in their ver tical position by means of a series of longitudinally and transversely arranged cords, r, which are looped around the tops of said springs, and are secured at their ends tothe side and end bars ot' the pivoted frames. A supplemental frame, consisting of side bars, I, and cud bar, J, is pivoted at its inner end in 9 the frame B, and contains a portion of the longitudinal and transverse straps q q ot' the section B, and also a part of the vertical springs and seeuringcords of said section. A bar, K, is hinged on the under side of the bar J, and is provided at each end with armsL, which are adapted, when the bar J is raised, to

IOO

assume a vertical or inclined position to enter one of a series of recesses, M, formed in a bearing-shoulder arranged on the inner face of each side bar of the section B.

To convert the device from a sofa arrangement, as shown in Fig. 2, to a bedstead, as shown in Fig. 1, it is only necessary to move the section A on its hinge devices c so that the same will lie in a plane parallel to that of the section B, after which the pins n can be moved in the slotted plate m, so as to exert a pull upon the rod o, thereby partially moving` the cams f and shaft F, so that said cams contact with the head j of the spring t' and lift said heads out of engagement with the plate lz, secured in each bar E, after which the entire section C can be swung upward upon its hinges s, parallel with the side and end bars of the sections A B, and be supported in said parallel position by means of the blocks G, which drop pendently, and form supporting-feet for the outer end portion of the section C. The pivoted headsection can then be moved to the position illustrated in Fig. 1, and supported by causing the arms L to engage one of the notches M in the bearing-rail of the section B. Vhen the parts are restored to their first position, of course the section A is simply folded over upon section B, the blocks G replaced in the recesses c, after which the section C is moved on its hinges so that its side bars E bear against the bar b of the central section and are automatically engaged by the headed spring t', so that said section C is rigidly held in said position to form the backsection for the sofa.

It will be obvious that the arrangement of straps and springs is such that when the several sections are arranged on a parallel line the said straps and springs present a springbottom for the bed, thereby dispensing with the necessity for an independent section, and thus rendering the device complete as to portability. What is morc,the head-section, composed of bars I J, can be readily adj usted at different inclinations, and when the device is used as a sofa be folded to rest on the bearingrails of the section B, so as not to interfere with said section, affording a positive seat for the section A when turned to rest thereon. The section Gis so hinged tothe section A that,when turned to the position illustrated in Figs. 2 and 3, the adjacent ends of the bars E b will present a seat adapted to take over a block, P, formed at each rear corner of the frame B.

as shown in Fig. 1,

It will be apparent that the device is not only of simple and durable construction, but of easy and ready operation and adjustment, and, moreover, possesses a degree of lightness essential for all requirements of portability.

I am aware of the constructions disclosed bythe United States Patent of J. K. Stockton, No. 136,276, granted February 25, 1873, and the patent of C. Pabst, No. 189,363, patented October 31, 1876; and I do not claim, broadly, any features set forth in either of said patents.

I claim- 1. In a combined sofa and bedstead, the y three sections A B G, hinged as described', and a head-section pivoted in the section B, and devices for supporting the same in an inclined position, substantially as set forth.

2. The combination, in a combined sofa and bedstead, of the three sections A B C, hinged as described, and the head-section pivoted in the section B, devices for supporting the same in an inclined position, and headed springs H for holding the section C at right angles with the section A, substantially as set forth.

3. In a combined sofa and bedstead, the combination of three sections, A B C, hinged together as described, and provided with springs arranged on a horizontal line, with cords on their upper face, and adapted to form a continuous bed-bottom, the section A being provided with the sides D, the section D with pivoted head-section, and the section C with pivoted blocks G, and headed springs H, carried by the section A, for holding the section C, together with its blocks G, at right angles with the said section A, substantially as and for the purpose set forth.

4. The combination, in a combined sofa and bedstead, of the section A, provided with the sides B, in which is securedthe spring t', having its head projecting as described, a section, C, hinged to said section A, and having side bars E, recessed to receive the ends of atransverse bar, F, carrying cams f, spring k,ar ranged as specified, and means for moving said cams to cause them to contact with said heads, substantially as set forth.

In testimony whereof I affix my signature in Vpresence of two witnesses.

JACOB LOEBIG.
