CONVERTIBLE CHAIR.

SPECIFICATION forming part of Letters Patent No. 365,344, dated June 21, 1887.

Application filed February 7, 1887. Serial No. 226,737. (No model.)

To all whom, it may concern.-

Be it known that we, ARTHUR B. LAWRENCE and JOHN S. BATOHELDER, citizens of the United States, residing at South Ashburnham in the county of Worcester and State of Massachusetts,have invented certain new and useful Improvements in a Combined Chair, Table, Music-Stand, and Easel-Holder; and we do 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 appertaius to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference i 5 marked thereon, which form a part of this specification.

The special object of the invention is to produce an article of furniture which shall subserve the several purposes ofa chair, table,

music-holder, and easel-support.

The invention will first be described in connection with the drawings, and then pointed out in the claims.

Figure 1. of the drawings is a perspective 2 view of the article when used as a'chair; Fig, 2, a similar view of it when used as a table;

Fig. 3, a longitudinal vertical section to show its use as a music or easel support; Fig. 4, a perspective detail view of the extensionleaf joint, and Fig. 5 a similar view of the slotted castings. Fig. 6 is a perspective view of one of the fixed eye-plates.

I11 the drawings, A represents the leg-frame of a chair, B the seat-frame, and O the back, the two latter being made separate and independent of each other. WVe make the seatt'rame sides I) 1) so as to form curved e'xtensions b b fiat on top,and which are provided with the fixed outer lateral headed pivots, 4O u I). i

D D are castings attached to the front of the back O,parallel to each other, and. provided with slots (1 d, the latter enabling them to slide on the said pivots b. By this means the 5 back 0 may first be turned in a horizontal plane and then slid forward until its center of gravity will be as nearly as possible coincident with that of the seat andleg frames A B.

E E are two metallic side arms pivoted to and near the top of the edges of the back 0, and having at the front ends the inside grooves,

e e, in which is held the connecting-bar e by the end screws,e On the under side of the bar 6 we locate the pins 6 e, which enter holes b I) in the seat'frame, so as to firmly support the back'G as a table-top. To one side of the back or table top .O,we joint the leaf 0 by means of the headed leaf-bolts c c and the fixed eyeplates 0 c on said back, the eyes being made of the key-hole form, so that the bolts may be 6 entered and slidforwardl In order to brace theleaf O, we pivot the bifurcated piece F to the under side of the leaf, and between these bifurcations pivot one end of the brace-arm G, which is made angular at 6 its free end,so as to fit 'on'the angle of the seatframe sides bb, asshownin Fig. 2 of the drawings. On the back and about the middle of the seat-bottom which is curved up at the rear,

We place the screw-eye G, and to this pivot the 0 hook H. while on the front of the lower part of the back we place another eye-screw, G, in which the hook latches, so that the back may be held at a forward incline While the pivoted table-support is thrown over on the rear of the back 0 to hold music or an easel, which rests on the bar 6 when the pivoted back is in the position shown in Fig. 3 of the drawings.

We are aware that a combined sofa and table is described in the expired Patent N o. 5,390; also,that a combined table, skirt-board, and sofa are described in the patent No. 54,140; hence we desire to disclaim everything shown and described in these patents.

Having thus described all that is necessary 8 5 to a full understanding of our invention, what we claim as new,anddesire to protect by Letters Patent, is-- 1. A combined chair and table formed with the leg-frame A,seat-frame B,and pivoted slid- 9o ing back 0, said back and seat-frame being connected to allow the back to turn and slide pivoted back, and a seat-fra1ne having the frame sides I) b, substantially as shown and (leholes b' bflwherebythe table may be supported scribed. in front, as specified. In testimony whereof we affix our signatures 3. The combination, with the table or back in presence of two Witnesses. 5 O, of the leaf 0, held thereto by a bolt-and- ARTHUR B. LAWRENCE. key-hole oint and supported by an oblique 7 n v 4 brace, said brace consisting of the pivoted JOHN BAICHLLDDR' piece Rand the blflCCflllll G, pivoted between Vitncsses: the bifurcations of the piece F, and angled at EPHRAIM S'roRs,

10 the end,so as to fit across the angle of theseat- A. A. ROCKWOOD.
