SPECIFICATION forming part of Letters Patent No. 420,197, dated January 28, 1890. Application led February l27, 1888 Serial No. 265,401. (No medel.)

To all whom it may concern:

Be it kn own that I, ASAHEL J. GooDwIN, of Brookline, 'county of Norfolk, State of Massachusetts, have invented an Improvement in This invention relates to beds especially adapted for hospital and invalid purposes, it having for one of its objects toprovide the said bed with an adjustable back-supporting frame, by means of which a firm support-is obtained for the back of the patient when in a sitting or reclining posture.

Another feature of my invention consists in providing the foot-board with a removable section adapted to be removed to permit a foot-bar to be substituted therefor, for a purpose to be hereinafter described.

Other features of my invention will be pointed out in the claims at the end of this specification.

Figure l is a top View of an invalid-bed embodying my invention; Fig. 2, a longitudinal section of Fig. 1 on line x, with part of the foot-board removed and with the foot-bar substituted therefor, the said figure showing next the foot end of the bed the portion of the foot-board which has been removed; and Figs. 3 and 4 are details to be referred to.

The bedstead herein shown as composed of the head-board ct, connected by suitable sidesv d2 to a foot-board having a fixed section a. and a removable section f2, may be of any usual or well-known construction. The sides a2 have screwed or otherwise secured to them, as herein shown, end boards or slats d4, to which are screwed, as shown, metal strips 0.5, having eyes to be'engaged by springs a6, forming part of a suspension-mattress, the body portion of which is herein shown as composed of links a7, united by squares or platesas, preferably of metal. c

On opposite sides and near the longitudinal center of the Wire mattress two of the links aT are replaced by rods or bars auhaving ears cd2, to which the links co7 are attached to complete the mattress. Each rod or bar al, beyond the side of the mattress, is embraced, as shown, by the slotted end of a bar b, having at its opposite end a hollow casting b', provided with a lug or ear b2, extended laterally from 1t, (see Fig. 3,) and the said bars on opposite sides of the mattress are joined together 'by a cross-bar b3, riveted or otherwise secured to the said lugs.

The side bars h and cross-bar b3, preferably made of bent sheet-steel, constitute a frame, to which is secured a covering h, of canvas or other material-*such as wire-netting-the said canvas being secured, as shown, tothe cross-bar. h3, and having its opposite end Vfastened by links b5 to the bars d10 and plates a8, extended across the mattress in line with the said bars. p

The frame and covering or back of canvas or other material constitute a support for the back and head of the patient, and the said support may be raised from a horizontal to an inclined position, or vice versa, as shown,by means of a windlass composed of a shaft d, having attached toit one end of a chain or chains d2; or it may be a rope, only one of which is shown in Fig. 2, the other end of the said chain or chains being secured to a crossbar cl3, having secured to or forming part of it bars, as d4, provided with holes at their ends to engage studs d5 on the side bars h of the supporting-frame. The bars cl" are locked to the side bars b, preferably, by springcatches, herein shown as pieces 4e of sheet metal, pivoted, as at e', and having their ends shaped to' engage the stud d5, to thus firmly secure the bars d4 to the side bars b of the supporting-frame.

It is a great desideratum to maintain the yielding back of the supporting-frame ltaut or under tension at all times and in all positions ofthe said frame, so as to presenta substantially rigid support for the back of the patient. This feature of my invention I have accomplished, as shown, by providing an adjusting-screw f for each casting b', the said screw being extended-into a threaded socket in thel said casting and normally abutting against the end of the side bar b. It will `th'usbe seen that the tension of the supporting-back may beV varied to suit the requirements of the case by turning the screws in or away from the mattress.

The bars com will preferably be equal in Y length to two links ci, to impart additional stiffness to the wire mattress at its sides, so that when the back-supporting frame is inclined to substantially an angle of forty-five degrees the downward strain of the side bars IOO the castings to move the cross-bar b3 toward Y b on the wire-netting of the mattress will be sustained, thus preventing sagging of the said mattress at the sides.

The upper portion or section f2 of the footboard is made removable, it having grooves, as f3, in its ends to engage notched ribs or bars f4, secured to the posts f5 of the said foot-board. Normally the removable section f2 will be placed on and form a part of the foot-board; but in case of sickness, as when a patient has sustained a fracture of the leg and itjs desired to maintain the injured member perfectly still, (which in practice is usually accomplished by means of Va weight secured to the said injured me1nber,) the said section will be removed and a bar f1U substituted therefor.

The bar f1o is provided at each end, as shown, with a socket, in which is located a spring f1?, adapted to bear against the end of a rod or pawl fw, having a stud f14 extended through a slot in the said bar, and by which the said bar may be moved to compress the spring, the said pawl engaging a notch in the bar f4 to secure the foot-bar inplace at any desired height.

The bed herein shown is provided with a stretcher-frame composed of side bars g g', having secured to them brackets g2, engaged by the ends of rack-bars g3, movable in guides g4, secured to the sides of the bedstead, the said rack-bars being made to travel, as shown, by a pinion g5 on a shaft g, rotated in practice by a handle from outside the bed.

The side bars g of the stretcher-framey have secured to them brackets Q7, which form with the top rail g8 of the side bars grooves or guideways to receive the ends of a board gw, constituting a table for the use of the patient. The side bars g of the stretcher-frame are joined near the head-board d by a crossbar Q12, thesaid stretcher-frame being not herein claimed broadly, as it forms part of the subject-matter of another application, Serial No. 265,365, filed by me February 25, 1888.

I claim,-v

Vl. The combination, with the bedstead and a suspension-m attress supported thereby and provided on opposite sides with rods or bars projecting therefrom, of a back-supporting frame pivoted upon said rods or bars, with means, substantially as described, to raise and lower the said frame on its pivotal points, as and for the purpose specified.

2. The combination, with the bedstead andv a suspension-mattress supported thereby, of an adjustable back-supporting frame pivotally secured to the sides of said mattress near its longitudinal center, bars d4, detachably secured to 'said frame between its upper end and pivotalV point, and means, substantially as described, independent ofthe mattress, to raise and lower the said bars, to thereby alter the inclination of the said adjustable frame with relation to the mattress, substantially as described.

3. The combination, with the bedstead and mattress supported thereby and provided with projecting rods or bars am, of an adjustable back-supporting frame secured to the said mattress, and comprising side bars b, slotted at their lower ends to embrace the outer ends of said rods or bars, and the crossbar b3, having secured thereto at its ends an adjustable hollow casting b', adapted to receive the upper ends of the side bars b, substantially as described.

8. In a bedstead, a suspension-mattress, combined with an adjustable back-supporting frame, comprising side bars b, pivoted to the mattress, cross-bar b3, covering b4, secured to the said cross-bar and to the suspensionmattress, and an adjusting device to move the cross-bar toward or away from the pivot-al point of the saidframe to vary the tension 'of the covering b4, the device `consisting of the hollow castings b', rigidly attached to the ends of the cross-bar, said castings be; ing provided with a threaded socket having an adj Listing-screw f extended therein and normally abnttin g against the end of the side bar b, extended into the casting, substantially as described. l
