lNVALlD-B EDSTEAD.

SPECIFICATION forming part of Letters Patent No. 276,515, dated April 24., 1883.

Application filed June 28, 1882. (No model.)

To all whom it may concern Be it known that I, REYNOLDS T. WHITE, of Boston, in the county of Sufiolk and State of Massachusetts, have invented a new and useful Improvement in Invalid-Bedsteads, of whichthe followingis a specification;

The object of my invention is to produce an invalidbedstead whereby the patient can be placed in any desired position, and to which a canopy and wheels can be attached, so that the same can be used as a carriage, and when not in use can be folded into a small compass, so as to be easy'of transportation or storage.

The invention consistsof ashallow rectangular frame which is supported by folding legs pivoted thereto, the head legs or supports consisting of long pieces pivoted to the frame near the foot portion and extending toward the head. To these long pieces is pivoted one end of a frame, the other end of which takes into a crook or socket attached to a sliding frame which works in guides on the sides of the rectangular frame,the sliding frame being operated by a screw in such a manner that when turned in one direction it tions, so that the headportion can be raised to any inclination desired by means of a crank and handle or screw, the body portion being stationary and the foot portion being made to rise or. be lowered, as desired, by means of a crank.

It further consists in dividing the mattress at each end into halves, thus making the mat-' tress so that it shall be of thelthickness of an ordinary mattress in the middle and like two thin mattresses on the. top of each other at the ends, by which arrangement the mattress is more easily adapted to the relative positions'of the three bearing-surfaces of the bedstead.

Referring to the'drawings, Figure l is a longitudinal section of a bedstead made according to my invention with the head and foot sections raised. Fig. 2 is a plan of same. Fig. 3 is a partial side view and section,'showing the wheel attachment and a modification of the means for raising the head-rest and foot-rest. Fig. 4 is a view of the front wheels and method of attachment. Fig. 5 is a view of one of the side wheels, springs, and method of attachment.

A-is a rectangular frame-say about eight inches deep-to which are pivoted, near the foot, two long pieces or legs, B, which extend toward the head, and are of such a length as to fold within the frame A, and to these legs B is pivoted one end of the frame G, the other end of which takes into a piece of metal, D, bent into the form shown, so as to form a crook or socket for the ends'of the frame 0. The 7 sockets D are secured to a sliding frame, E, which works in guides at a on the sides of the frame A. To this sliding frame E is attached a nut, b, through which'the screw 0 works. The outer end of the screw is secured to and so as to turn freely in the frame A, and is made square at the outer end for thehandle d to fit on to turn the same, so that by turning the handle d in one direction the screw 0 will draw the sliding frame E toward the head of the bedstead and force out the frame 0, together with the leg B, until the desired height or inclination of the frame A is attained, and by turning the handle in the opposite direction the sliding frame E is forced toward the center of the bedstead, and .the frame A is thus lowered until the leg B is folded within the frameA. When the wheels are attached the leg B is drawn up into the frame A.,

The foot-legs F are pivotedto the frame A,

and are made the length that it is desired to have for the normal height of the bedstead, and so that they will fold up clear of the leg B. The legs F when extended are held in position by means of the braces e, which are hooked onto studs on the legs B.

G is a head-rest, which is raised and lowered by means of two arms,f, on a rod, 9, which is operated by a handle, E. This handle is composed of a flat bent piece of metal, It, with a wooden block, 43, fixed thereto to take hold of, and has pivoted to it a short lever, j, on the end ofwhich is a stud or pin, which passes through the piece h into holes formed in the side of the frame A. On the opposite side of the pivot, between the lever j and the piece h, is placed a spring, which keeps that end pressed out, and consequently forces the pin into one of the holes in the frame A. The head-rest Gr may be operated by a screw, as shown in Fig. 3. In this case the arms f are bent at right angles at their ends and take into loops or staples on the under side of the head-rest. The rod g is secured to a block, 70, which is free to slide in guides. To the bottom of the block 70 is secured a nut, Z, through which works the screw m in a similar manner to that described withreference to the screw 0.

H is a foot-rest, which is capable of being raised above, as shown in full lines, Fig. 1, or lowered below the ordinary level, as shownin dotted lines. To operate this rest I employ a rod, a, bent into the form of a crank, (best seen iuFig. 2,) the ends of this cranked rod having their hearings in the frame A. One end of said rod is formed square, onto which is fitted a handle, H, made as before described. This crank it is fastened near one end of the foot-rest by means of loops or staples and at the other end of the foot-rest are pivoted two arms, 9, which are secured at their other ends to blocks q, attached to the inner sides of the frame A. By this arrangement the foot-rest H is kept parallel with the frame; or the footrest H may be operated by means of a screw,

T, and sliding frame U, as shown in Fig. 3. The frame U is free to slide in guides u, and

has secured to it a nut, 12, through which the screw T works. The foot-rest H is connected to the sliding frame U by the arms 1) n, and one end bears or slides against a curved block or guide, V, which causes it to rise when the screw is turned in the direction to draw the frame U toward the foot end of the bedstead, and lower when the screw is turned in the reverse direction. In some cases when it is desired to have the foot-rest higher at one end than the other, the arms 10 may be made to extend, as shown in dotted lines,,Fig. 1, and provided with a long slot, through which a thumbscrew is passed for securing the same in any desired position.

For operating the head or footrest, or both, instead of the handle H, a quadrant with notches in its face, into which a spring takes for holding it in any desired position, might be employed; or a worm-wheel might be .fit-- ted on the ends of the rod 9 or it, into which a worm takes, so that by turning the worm the rest would be raised or lowered, as desired..

To each corner of the frame A, I fix sockets I, into which are fitted standards J, which carry the drapery S. The standards J are formed with a shoulder to fit onto the frame. Below the shoulder they are made of an angur lar form, so as to fit into the openings left between the sockets I and the corners of the frame A. They thus fit around the corners of the frame A, and the standards J are made to spring outward, so that when the canvas is placed on the top all sagging is prevented.

Any kind of drapery may be employed as desired or required.

To adapt the bedstead for out-of-door use, I attach wheels L M at the front and sides of the frame A. The front wheels, L, are carried by the swiveled brace N, Fig. 4, the upper end of which passes through an opening in the clamp P, and is secured by the nut 19, so that the axle will be free to turn in any direction. The clamp P has also on its lower side a lip, which passes up inside the frame A, so that when the thumb-screw is turned down to bear upon a plate on the top of the frame A, the clamp P will be securely held on the frame. A handle can be attached to the axle-shaft Q, so that the bedstead can be drawn by hand or otherwise. The clamp P, which carries the large hind wheels, is provided with a box at its side, in which a spring, q, is fitted. It is also provided with a V- shaped groove, into which the bossr, which carries the wheel M, fits. To the top of the boss 1' a short rod, s, is connected, which passes up through the spring-box, and is provided with a head, so that when any irregularity of the road occurs the spring will yield, and thus prevent any sudden shock to the patient.

The mattress K is made in two parts separated horizontally, as shown, at each end for about one-third the length of the mattress, more or less, the central portion being made solid, as in the ordinary mattress, by means of which construction the mattress will yield and adj ustv itself readily to the various changes in the position of the head and foot rests and the body of the occupant.

In the drawings 1 have shown slats for sup,- porting the mattress; but sacking, springs,or other suitable supports may be employed.

What I claim as my invention is 1'. An adjustable invalid-bedstead consisting of the rectangular frame A, with. headrest G, foot-rest H, and leg B, in combination with the frame 0, sliding frame E, the screw 0, and nut I), substantially as shown and described.
