Be it known that 1 WALLACE N Mason, a citizen of the United States, residing at Richburg, in the county of Allegarr, and State of New York, have invented new and useful Improvements in Devices for Handling invalids, of which the following is a specification.

My invention relates to means for moving a disabled person upon, or from a bed or couch with the least possible arring or discomfort to the patient. It is adapted for turning the patient partly 'or entirely over; or for drawing him bodily toward the head end of the bed, upon the pillow; or for lifting hirn upward above the bed sulliciently to change the bed clothing, or .for the use of a vessel, or to such a height as will permit the removal of the bed-stead and the substitution of another bed or of a couch. He may also, if desired, be lowered to a mere mattress or to the floor.

This machine is not a bed, or any part of one, but may be used to support the patient, hammock like, with great comfort, independently of a bed stead. The device is portable being constructed for folding into a small compass, so that a man can easily carry it. It can be manufactured at a cost so small that every physician may own one or more. F or hospitals and sanitariums its value is beyond computation.

The accompanying drawings illustrate the device, its various features being referred to by letters, similar letters indicating corresponding parts in the several views.

In the drawing Figure 1 is a side elevation of the device partly broken away, in operative position about a bedstead. Fig. 2 is a head-end elevation with the bedstead removed. and the sides rather closely adjusted. Fig. 3 shows the back supporting device when raised to an approximately vertical position, and viewed from the head end of the bed. The canvas is shown fragmentarily and one of the pockets is partly broken away to expose the leg therein. Fig. 4i is a view of a post and cross bar as seen in Fig. 2 but folded up. and Fig. 5 shows the main roller E divested of canvas and folded up.

The reference letter A designates a post or standard of the supporting frame, of which there are four, all substantially alike, and each provided with a foot piece a. Each post is made vertically adjustable by any preferred means: it is shown in the drawing to be made in two sections one sliding vertically upon the other, and maintained in contact by hands a on one section and embracing the other section. A supporting loop it on one section is adapted to engage notches e on the other section, and a set screw 0 binds the two sections adjustably together.

E ch standard is attached, at is upper end, to a cross-bar which is made in two sections. These sections are lu'irizontally adjustable in being movable upon each other, and are maintained in mutualcontact by bands I), b. Two standards and their connecting cross-bar constitute a frame; and in order to render these frames conveniently portable, each standard is jointed to its cross-bar, preferably, by a hinge I) at the inner angle thereof, and an external angular plate I) fixed on the bar is provided with a set screw 1/ for attachment to the standard Bearings l), l), on the cross-bars B, are provided for the main rollers I); said rollers having recesses c near their ends, to engage said bearings 1). These rollers may be made rigid, or be jointed by having a hinge a on one side, and opposite thereto a plate 6 held by set screws 0, or by any other preferred means. Pins F on these rollers engage holes at the opposite edges of a canvas or cloth G, so that by means of a crank c the canvas may be wound upon said rollers. The canvas may be of any desired length, and a pin 7* adapted to engage a hole r in the cross bar is provided to prevent premature reverse movement of the crank.

As thus described the device is adapted for all ordinary purposes, but in order to bring the patient to a sitting posture, l have provided a back support, formed of a "frame, comprising a cross-bar i and two legs 1, connected therewith. These legs lit into pockets l'l, formed on the under side of the canvas G and which open, under its edge, at the head end of the bed, with their bottoms extended toward the foot of the bed. The upper end of each leg has an extension 'i of reduced diameter, which lits into a loop i on the cross bar and extends beyond it sullicicntly to engage loops K on cords 7;, which reach to the foot end of the device and are connected to a roller L supported in bearings m attached to the cross bar B. By means of the crank 'n on said roller the cords arc woundupon the roller L and the back-supporting frame I, i is brought to the desired position.

Patients frequently work down toward the foot of the bed, and in order to draw them up upon the pillow I have provided bearings 0 on the cross bar at the head end of the device which support a roller P having a crank 2). Holding pins on this roller engage holes in the end of a strip of canvas R. By turning a roller E the patient is turned upon his side and the canvas R is laid upon the bed. He is then turned back upon this canvas, Which is then drawn toward the head end of the bed by the crank p, which also lifts his head and shoulders upon the pillow.

The pillow, in Fig. 1, is shown to be at the same end of the device as the cranks e but it may be put at the opposite end if desired, in which case the roller L must be placed in the bearings o. It should be noted thatthe short rollers L and P, are reversible as to their ends, and are also exchangeable with each other. And this is true also of the main rollers E, E.

Having now described the invention and the manner of using it, what I claim and desire to secure is l. A device for handling invalids comprising two frames, each frame composed of two standards and cross bars thereon, a hinge at the inner angle formed by said standard and said cross bar and an angular plate on the outer parts of said standard and cross bar,

said plate being secured to said cross bar and detachably attached to said standard by a set screw as stated.

2. In a device for handling invalids formed of a supporting frame composed of standards, cross-bars, and rollers having a lifting canvas thereon, bearings m on a cross-bar B, a cordroller L provided with a crank in said bearings m, cords on said roller L having terminal loops, a back support attached to said canvas at the side farthest from said cord-roller, and means on said back support to engage the loops on said cords, as herein set forth.

3. In a device of the character described, the combination With a supporting frame composed of standards, cross-bars and rollers with a canvas G thereon, of bearings 0 on one of said crossbars, a roller P in said bearings 0, a crank on said roller P, and a strip of canvas R, having one end attached to said roller P and its other end unattached, said canvas B being adapted to be laid upon said canvas G, for the purpose specified.

In testimony whereof I afiix my signature, in presence of two subscribing Witnesses.
