COMBINED CHAIR AND BED.

SPECIFICATION forming part of Letters Patent No. 276,774, dated May 1, 1883,

(No model.)

To all whom it may concern:

Be it known that I, STEPHEN A. D. CLARK, of St. Joseph, in the county of Buchanan and State of Missouri, have invented a new and Improved Combined Chair and Bed, of which the following is a full, clear, and exact description.

The object of 'my invention is to provide a new and improved chair, which can be adjusted in various positions and can beexteuded to be used as a bed.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a rear elevationot' my improved combined chair and bed. Fig.2 is a longitudinal elevation of the same, showing it raised for use as a chair. Fig. 3 is aplan view of the same, showing the same extended for use-as a bed. Fig. 4c is a longitudinal elevation of the same, in this position parts being broken out and others shown in section. Fig. 5 is a detail perspective view of part of side rail, showing a modification in construction.

Two standardsorlegs,A,of wood or metal,are secured and properly braced on a suitable base, B, and to the upper ends of these standards the sidebars, G, of the seat-frame are pivoted. The side bars, D ,of the back frame are pivoted to the rear ends of the seat side bars, (1, and the side bars, E, of the leg-rest frame are pivoted to the front ends of the seat side bars, .0. A footrest, F, projects outward from the upper sur- 5 faces of the lower end of the leg-rest frame. A quadrant-rack, G, projecting upward from the rear end of the seat side bar, 0, and a quadrant-rack, H, projecting downward from the front end of theseat side bar, 0, are preferably made integral, and one of these rackframes is attached to each side bar,0. These quadrant'racks may be made separate and independent of each other; but I prefer to make them integral, as this simplifies the construction and makes the chair more durable. bar, I, is passed edgewise transversely and loosely through the side bars, I), of the back frame at such a height from the pivoted ends of the side bars, D,that it can pass in between 50 the teeth of the racks G. This bar I is provided at the ends with handles 1, and with notches c in the lower edge and at the sides of the quadrant-racks G, which rod is pressed by a spring, J, attached to one side bar, I), and to the bar I in the direction toward that side of the racks G at which the notches a are provided. The bar I is provided with longitudinal slots 1), through which pins or studs d pass. which also pass through the side bars, D, ot'the back-rest. A bar, K, passesedge- 6e wise and transversely through the standards or legs Ain such a manner thatits upper edge can pass in between the teeth of the quadrantracks E. This bar K is provided withnotches f in the upper edge at the sides of the racks H,

and is pressed in that direction toward which the notchesfare from the racks H by a spring, L. The bar K is provided with handles K at the ends. An arm, M, projects downward from the lower end of each back-rest side bar, I), which arms are rigidly attached to these sidebars, D. Connecting-rods N are pivoted to the lower ends-of the arms M, and to lugs or jaws O, projecting from the under sides of the side bars, E, of the leg-rest. A series of headed pins or pegs, P, are driven about equidistant into the upper surfaces of the side bars, 0', D, and E. Cords Q pass around the pegs P and through the covering R at the edges of the same, and around rods S, held against the under side of this covering at the edges by the cords Q. The upper ends of the cords Q are secured or fastened on abutton, hook, cleat, or equivalent device, T, on the rear side of the top cross-piece of the chair-back, by means of material, and extends in one piece through all the sections of the chair. The rods S are pro- 9o vided with eyes or loops gat the ends of each section, as shown in Figs.1 and 3. A bracketarm, U, projects back from the cross bar V, connecting the legs A, and a plate, U, is attached to the free end of this bracket-arm for receiving a chamber or other suitable vessel. The covering R is provided at the rear part of the seat with an opening, W, which can be closed by a transverse truss, X, passed under the covering R and provided with apertures h I00 for securing it on the pegs P; or it can be secured by buckles or other suitable devices. The back, seat, leg-rests, standards A, and the base-rails are connected by suitable cross-- bars Y.

Without departing from the spirit of my invention, rollers I may be used in place of the pins P, around which rollers P the cords Q pass. The rollers are contained in suitable recesses in the rails O,D, and E, as represented in Fig. 5.

The operation is as follows The bar I, catch ing between the teeth of the racks G, locks the back and theleg rest (which are connected) in place, and the bar K, which catches between the teeth of the racks H, locks the seat in place. By pushing or pulling the bar I in the direction of the arrow a, Fig. l, the notches a will be brought over the racks G, and the racks can pass through these notches without catching on the rod I, and the back of the chair can be swung in' the direction of the arrow 11 or in the inverse direction as much as may be desired. If the back is swung in the direction of the arrow b, the leg-rest will be raised in the direction of the arrow 0, and vice versa. It the back is raised the leg-rest will be lowered. As soon as the bar I is released the spring J throws it in the inverse direction of the arrow a, and the back and leg-rest will be locked in position. The back can be lowered and the leg-rest raised until the back, seat, and leg-rest form a horizontal platform, as shown in Figs. 3 and 4:, which can be used as a bed or operating table, or for similar purposes in sick-rooms and hospitals. If the bar K is pushed or pulled in the direction of the arrow at, the racks H will be released, and the Letters Patent, is-

seat can be turned on its pivot and will be antomatically locked in any desiredposition as soon as the bar K is released. If the patient wishes to relieve himself, the band X is removed and a chamber or other suitable vessel is placed on the plate U, directly below the opening WV.

Dentists and barbers chairs can also be constructed in the manner described above.

Having thus fully described my invention, what I claim as new, and desire to secure by 1. A seat-frame having its side bars, 0 C, pivoted to standards A, in combination with a front leg-rest frame and a back frame, respectively, pivoted to the forward and rear ends of said seat-frame, as shown and described.

2. The combination, with the pivoted seatframe having rack G, of the bar I, having notches a in the lower edge, and the slots 1), the pins d, and the back-frame side bars. D, having holes for the pins, and the spring J, as shown and described.

3. The combination, with the bar K, having handles K and rack H, of the back-frame side bars, D, having arms M, the pivoted rods N, and the side bars, E, having lugs O, as described.

4. The combination, with the covering It, of the eye-rods S, the bars 0 I) E, having the pins P, the cords Q, and the chair-back cleat 70 T, as described.
