UNITED STATES PATENT FFIQE.

JAMES J. BOWKER, OF LA OTTO, INDIANA.

INVALID-BED.

SPECIFICATION forming part of Letters Patent No. 277,208, dated May 8, 1883. Application filedMarch 17, 1883. (No model.)

To all whom it may concern:

Be it known that I, JAMES J.BOWKER, a citizen of the United States, and a resident of La Otto, in the county of Noble and State of Indiana, haveinvented certain new and useful Improvements in Invalid-Beds; and I 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 appertains to make and use the same, reference being bad to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure l of the drawings is a side view of my bed. Fig. 2 is a bottom view. Fig. 3 is a vertical sectional view of the same, and Fig. 4 is a detail view.

This invention has relation to invalid-bedsteads or adjustable cots or lounges; and it consists in the construction and novel arrangement of the right-and-left screw-brace having the wedge-form attachment ends adapted to engage slide-seats on the framing, the raised and grooved side bearings of the side bars, the side pulleys, and the rope-supports extending from said pulleys to the hinged head portion of the frame, the sectional and removable shaft in connection with the side pulleys, and the supporting-ropes for the head portion of the frame, the sliding head-rest having spring-arms engaging the sides of the head portion of the frame, and the sectional adjustable brace engaging the transverse bars or braces of the main frame and head frame or back, all as hereinafter set forth.

In the accompanying drawings, the letter A designates the main frame, and B the head portion or back frame, the side bars I) of which are hinged to the side bars a of the main frame.

0 indicates the canvas bottom, which extends across between theside bars of the framing, to which it is attached. The side bars a of the main frame are provided with legs D. On the side bars a, near the ends adjoining the back frame, are provided raised bearings E, which may serve as arm-supports.

These bearings are curved in convex form on their upper edges, 0, which are grooved to form seats for the supporting cords or ropes d, which are attached each by one end to the the sectionalshafts e of which are journaled tions 1 of the shafts e are removable, in order that the cot or lounge may be folded together when not in use.

Covering-plates n extend over the grooved rope-bearings E to protect the ropes and provide a guard to prevent the arm or hand of the occupant from coming in contact with said 'ropes. i

F indicates a sliding head-rest having at each end a downwardly-extendin g spring-arm, G, the lower end of which is turned inward, forming acatch, p, which engages the under edge of the side bar 11 of the back frame, B. The head-rest therefore can easily be adjusted to a higher or lower position. The side bars of the framing are strained apart to brace the frame in position and stretch the canvas by means of the right-and-left screw-braces H, each of which consists of the right and left screws K, respectively working in threaded bearings s in opposite ends of a central nutsleeve, L. The right and left screws K are each provided with'a wedge-form foot or flan ge, 2, at the outer end, which is designed to engage a slide-seat, '0, of tapering form on the side bar. These screw-braces H are therefore detachable, being easilylifted out of the slideconnected by means of a sectional adjustable brace, P, the arms of which are provided with strap-loops t, engaging annular groove-bearingsj of the nut-sleeves L. The adjacent ends of the arms of the sectional brace are connected by strap-bearing and set-screw to form an adjustable lap-joint.

This cot or lounge bed is easily adjusted by back frame and by the other end to pulleys E, turning the shaft to which the pulleys are connected, and thus raising or lowering the head portion of the frame. The adjustment is secured by means of an arm, S, connected to the outer end of the shaft, which engages a rackcatch, Z, which is secured to the side of the frame.

Having described this invention, what I claim, and desire to secure by Letters Patent,

1. In a folding cotor lounge, the right-andleft screw-braces having wedge-form attachment ends adapted to engage slide-seats 011 the framing, substantially as specified.

2. In a. folding cot or lounge, the pulleys and cord attachments to the back frame, the raised grooved hearings on the side bars over which the cords pass, and the device for securing the adjustment of the pulley-shaft, substantially as specified.

3. The sectional shaft of the pulleys, consisting of hub portions and detachable lapping shank portions, adjustable with reference JAMES J. BOWKEE. Witnesses:
