lNVALlD-CHAIR.

SPECIFICATION forming part of Letters Patent No. 406,313, dated July 2, 1889.

Application filed February 8, 1889. Serial No. 299,146. (No model.)

To all whom it may concern.

Be it known that I,W1LLIAM SMITH, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Invalids Chairs, of which the following is a specification.

My invention relates to an adjustable chair for invalids, and is illustrated in the accompanying drawings, in which Figure 1 is a side elevation of the chair, showing the foot-rest drawn out, and indicating by broken lines the sliding chamber-support. Figs. 2, 3, and 4 are top, side, and front Views, respectively, of the upper sliding drawer. Fig. 5 is a top View of the chambersupporting drawer detached from the sliding support. Figs. 6 and 7 are side and top views, respectively, of the chair adjusted to serve as a bed. Figs. 8 and 9 are views of the seatcushions. Fig. 10 is a front elevation of the chair. Fig. 11 is a vertical cross-section of %he chair-seat frame on the line indicated in The chair-seat frame A has a lower slidedrawer B, which carries a foot-rest cushion B, and at the front moves in and out on slidestrips a; an upper slide-drawer G, which carries the chamber-supporting drawer C, and at the front moves in and out on slide-strips b; and said frame also has an intermediate slide D, to which the back-supporting jack D is attached, and at the back moves in and out on slide-strips c. The slide D is between the lower drawer B and the upper drawer O. The foot-rest drawer B may be drawn out or push ed back in the seat-frame, as desired.

The chair-seat A has a hole d for a chamber, which may be supported by its top flange engaging with the seat. It also has a cushion E, which is provided with a hole cl, and a plugcushion e to fill said hole.

The chair-backF is hinged at f to the seatframe A, and may be tilted backward or inclined, as shown in Fig. 6. The back is provided on its rear with a rack-bar g, which extends up and down the center, and the supporting-jack D has a leg which rests on the floor, and a stud which engages with the rack-. bar and sustains the hinged back at any in- A head-board H is hinged at'i to the top of the back F and projects upward. It is provided on its back with an arm j, which projects down below the said hinges z, and a linkbar L has one end jointed at k to the end of the said down-projecting arm on the headboard and the other end jointed or hinged at m to the seat-frame. This construction and combination of parts results in causing the hinged head-board H to tilt forward as the back F tilts rearward. In other words, as the back tilts rearward the head-board will not tilt in the same way, but will preserve and keep nearly the same perpendicular position. The head-board thus serves, when the back F is upright, to support the invalids head, and when the back is horizontal it serves to hold a pillow from falling off.

The upper sliding drawer 0 serves two purposes-to wit, to support the chamber-drawer O and to support the cushion G which serves in part to form a couch. This drawer has cross slide-strips n, and a chamber-supporting drawer O is movable laterally in said slide. A chamber 0 is supported by this crosswisemoving drawer C'. The upper drawerv O has a hinged cover 19, (see Fig. 4,) which closes down over the chamber 0, and a pivoted stud q works in a slotin the top of the upper drawer, which, when turned upward, as seen in Figs. 3 and at, serves to sustain the hinged cover when the latter is raised.

l Vh en the chamber is to be used, the drawer O is drawn out laterally, the chamber placed in the hole therein, the cushion E, with the hole therein, from which the plug 6 has been removed, is placed upon the seat, and the cover p and stud q elevated to form the seat for the invalid. The cushion C is removed when the drawers 0 and G are closed in.

' IOO It is proper to state that a chamber cannot be in the seat-hole (Z of the chair-seat A when the upper drawer C is back in position, but may be there when the said drawer C is drawn out at the front.

It will be seen that the various parts of this chair may be adjusted and changed to meet to said sliding drawer, substantially as specified.

As an improved article of manufacture, an adjustable chair having its seat-frame A provided with drawers B and C, movable in and out at the front of the seat, and the latorally-moving drawer O, the slide D, interposed between the drawers B C and sliding to the rear of said seat, said slide being; provided with a jack D, adapted to engage the rack-bar 011 the back of the chair when said back is lowered, said slide also provided with a leg D which rests on the floor to support said back, substantially as specified.

In testimony whereof I afiix my signature in the presence of two witnesses.

\VILLIAM SMITH.
