INVALID-BEDSTEAD.

SPECIFICATION forming part of Letters Patent No. 270,912, dated January 23, 1883.

Application tiled July 27, 1889.1 (No model.)

To all whom it mag/concern Be it known that I, JOHN Q. A. SARGENT, of Manchester, in the county of Hillsborough and State ot' New Hampshire, have invented certain new and useful Improvementsin Invalid- Bedsteads, of which the following is a speciiication.

The object of my invention is to provide an invalid-bedstead with certain devices and attachments adapted to facilitate the treatment of patients having bed-sores,and permit parts of the body in contact with the bed to be bathed and dressings applied to wounds in those situations without moving the patient, and render ventilation and defecation more rapid and efficacious; and it consists in the construction, combination, and arrangement of the several parts of the bedstead, hereinafter more fully described, and set forth in the claims.

y Figure l represents a vertical section of a bedstead embodying myinvention. Figi! represents an end elevation ot' the same. Figs. 3, 4, 5, 6,'and 7 represent detached sectional views of parts herein described, shown on an enlarged scale.

A represents the side rails ot' the bedstead, and B represents thev end rails of the same, and are permanentlyconnected together at the corners by angle-irons C, extending each way a short distance upon the top, bottom, and outer face of the rails, and secu-red by screws or in any suitable manner. These an gle-irons` C are provided with a vertical hole or opening, formed slightly tapering from the bottom upward, and into which are tted the corner-posts D, the upper ends of which enter holes formed within the under sides 0f the head and foot rollsE of the head and foot boards F, and are provided with suitable shoulders to support the said angle-irons and rolls E, whereby the said posts are temporarily connected with the rails of the bed-frame in a very simple and expeditious manner when in use, as the weight ofthe occupant tends to force them more rgidlyinto their fittin gs, and when desired to transport the bedstead the said posts D are easily and quickly removed downward from their connections with the rails and head and foot boards, which are hinged to thc tops of the end rails, and may be closed inwardly upon the bed-bottom, composedot' aseries of supporting-straps, H, which pass through suitable apertures in the bedrails, and are held in place by pins a, inserted in loops in their ends. Two or more of these loops are provided at one end of the. support.- ing-straps for adjusting them to the proper height or tension. Along the under side ot' one of the side rails extends a rod, K, having at each end a screw-gear, J, engaging with pinions b on cross-rods G G at the head and foot of the bed. These cross-rods have secured to theta, bymeans of staples C C', lifting-straps L L` provided at their lower ends with links or loops M M, adapted to engage with corresponding hook-brackets, N N, secured to the head and foot or end rails ofthe trundle-bed O, provided with a mattress, and intended to be suspended by the straps L L, the loops or links M M of which are caused to engage with and disengage from the said hooked brackets N N by incline projections e, extending vertically upon the outer face of the brackets from their lower ends, and terminating a short distance above, so as to be received within the opening of the said link when it is connected therewith in the act ol' lifting the trundlebed, whiclnupon being lowered until it rests upon the door, and then the said suspension-straps L being lowered a short distance, the upper portion ofthe said links are brought in contact with the fac-e of the incline projection of the brackets, and thus forced out- Ward from the hooks, resting out of a vertical plane until drawn upward, when they again assume a vertical position and engage with the hooks or brackets. The rod K projects within a socket at one end or both ends ofthe bed-frame, and is adapted to receive awrench having a crank, by which the said rod may be revolved or turned.

The trundle-bed, being provided with a mattress, is run under the main bed in the proper position to engage with the said suspensionstraps L. A wrench or crank is applied to the end of the horizontal rod K to turn it, when the trundle-hed is elevated until the supporting-straps H lie loosely upon its mattress and the mattress supports the patient. The trun- ICO die-bed may be lowered and removed in like manner to accommodate the various needs of the patient without removing him, he resting in the meantime immediately on the straps. While the trundle-bed may be thus 'lowered and raised the supporting-straps can be made tight or loose by means ot their holding-pins, as may be required for the comfort of the patient or convenience ot' the attendant.

Now, in order to elevate the head of the patient,I have provided an adjustable head-rest, P, consisting of any suitable flexible material, secured to the curved side bars, t, which are pivoted at their front lower ends to the side pieces, S, which are provided with dowels or pins titting within corresponding holes in the 'top ot' the side rails,A. rlhe side pieces, S, are

connected together by cross-pieces T, the rear Vone being constructed with a cross-rod, U, each end of which is provided with a bevel-gear, V, connectingwith a like bevel-gear, g, t ted upon the rear ends ot the adjusting-screws W,Whicl1 are connected with the sliding cross-bar Y, which is provided with corresponding` screwnuts, and to the ends of which are pivoted the supporting-braces Z,their opposite upper ends being pivoted to the curved side bars, lt. A wrench or crank being applied to the end ot' the cross-rod U, it may be rotated, and thus revolve the adjusting-screws W, so as to slide back or forth the cross-bar Y, and thereby elevate or depress the head support or rest P, as desired, or to any angle less than forty-five degrecs, so as to elevate the patient into a sit ting position.

I have also made provision for elevating the foot or leg of the patient when desired, and for this purpose a vertical slotted bar, d, is provided, with a hook at its upper end to engage with the top roll or edge of the foot-board, and an adjustable friction-roll is journaled in one ot' a series ot' holes passing through the slotted portion of the said bar by means of a pin, t.-

A suitable banda ge being placed upon the foot, and a oord attached to the same and passed over the friction-roll or grooved pulleyT n, and a weight, w, attached thereto, the limb may be heldin an elevated position, free from the bed,\vhile dressings are being applied thereto, or as occasion may require.

Having thus described my invention, what I claim isl l. The combination, with the suspensionstraps L, provided at their lower ends with links M, ot' the hooked brackets N, provided with the inclines e, substantially as described, as and for the purposes set forth.

2. The combination, with the bedstead-rails, ofthe angle-irons C, having a vertical opening, and the removable posts D, as and for the purposes set forth.

3. The combination, with the bedstead-rails and removable posts, of the hinged head and t'oot boards, adapted to be held in'a vertical position by said posts, and to be folded after the posts have been removed,substantially as described, as and for the purposes set forth.

4. The combination, with the foot-board, ot' the hooked slotted bar having an adjustable trictionpnlley, substantially as described, as and for the purposes set forth.
