PATENT FELIX M. LEPORE, OF DENVER, COLORADO.

INVALIIDS BED.

$PECIFICATION forming part of Letters Patent N 0. 654,165, dated July 24, 1900.

Application filed November 6, 1899. Serial No. 736,029. (No model.)

To ctZZ whom it may concern.-

Be it known that I, FELIX M. LEPORE, a citizen of the United States of America, residing at Denver, in the county of Arapahoe and State of Colorado, have invented certain new and useful Improvements in Invalids Beds; and I do declare the following to be a full, clear, and exact description of the intiers of an occupant to an inclined or to a sitting position; second, to provide means for elevating the body of an invalid above the bedstead to any desired position for surgical or other purposes, and, third,to provide means for folding the bedstead up for storage when not in use. I attain these objects by the mech-- anism illustrated in the accompanying drawings, in which- Figure l is a side elevation of a bed embodying my invention. Fig. 2 is a plan View of Fig. 1. Fig. 3 is a cross-section of Fig. 1 on line A of the bedstead. Fig. 4 is a perspective view of the lifting-sheet and its roller, and Fig. 5 is a perspective view of the lifting-sheets supporting-frame.

Similar figures of reference refer to similar parts throughout the several views.

Referring to the drawings, the numeral 1 designates the corner-posts; l, the legs of the corner-posts; 2, the side rails; 3, crossslats which rest on a projecting strip forming an integral part of the side rails.

A headboard 4C and a footboard 5 extend between the corner-posts. I will term a tilting frame, rests on the cross-slats and fits loosely between the side rails and the head and foot boards. The head end of this tilting frame. is pivotally jointed at about one-third of its length from the head end by the bolts 7. Under the head portion of this tilting frame and across the sides a shaft Sis journaled in bearings 9. At

A frame 6, which" one end a ratchet-wheel is secured on the outside of the side rail, and a crank 11 is fitted to the end of the shaft, which is squared to receive it. A pawl 12 is pivoted to the side of the rail and engages the teeth of the ratchet and is kept in mesh withthem by a spring 13. A projecting pin 14, which is secured to the pawl, enables the pawl. to be raised by the hand of an operator out of mesh with the ratchet-wheel.

Upon the shaft adjacent to the opposite sides of the frame two lifting-arms 15 are mounted, which are formed to extend over the end cross-slat and under the end of the frame 6. The ends 16 of these lifting-arms are curved downward, so that, by turning the shaft by means of the crank, they are raised, as shown by the'dotted lines 17, and they will bear and work smoothly against the under side of the end of the frame.

Across the end of the frame 6 aroller 18 is mounted in brackets 19 at each end which are secured by the screws 20 to the side pieces of this frame. This roller may be a common form of a spring-operating curtain-roller or a plain roller which can be turned by hand. A sheet or blanket 21, which is shown in Fig. 7, is secured to it. The sheetis normally rolled up on the roller, as shown in Figs. 1 and 2. The free end of this sheet contains eyes 22 and hooks 22 at its corners or other suitable means for detachably fastening it to the eyes 23 of the lifting-frame 24: when it is unrolled for use.

The lifting-frame 24, which I wi1l term the sheet-lifting frame, consists of the side arms 25, which are pivotally connected by the bolts 26 to the outside of the sides of the frame 6 and to its head portion and between the sides of this frame and the sides of the bedstead. The opposite ends of the sheet-lifting frame are bent downward and extend to near the level of the ends of thelegs of the corner-posts and curve slightly toward the pivotal end of its arms. At their lower ends they are turned toward and are connected together byan integral rod portion 27, as shown in- Fig. 5. From their free upper ends a lateral eye 23 extends over the top of the frame 6, to which the hooks of the sheet areattached. Two ropes 28 are attached to the rod portion 27 of the sheet-lifting frame. They extend over the roller 29, which is supported in suitable bearings 30, attached to the under sides of the side rails of the bedstead and extend to the winding-drum 31, to which they are attached. The drum is supported by a shaft 32 in bearings 33, secured to the under side of the side rails of the bedstead. A ratchetwheel 34 is secured to the shaft on the outside of one rail, and a crank 35 is fitted to the end of the shaft adjacent to the ratchet-wheel, which is squared to receive it. A pawl 36-is pivotally attached to the rail and meshes with the ratchet-wheel and is held in operative engagement therewith by a spring 37. A pin 38 projects from the side of the pawl and enables it to be raised to disengage it from the ratchet when it is desired to lower the sheet and its lifting-frame from its raised position, which is shown by the dotted lines 38, to which position it is raised by winding the rope on the drum by turning the crank, the pawl and spring locking and holding the drum from unwinding whenever the crank is replaced.

I have arranged the bedstead so that it can be folded up when not in use, so that it may beeasily stored away or placed at the side of a room or in a closet. In carrying out this feature of my invention I have hinged the posts and legs. Thus the top of the posts are hinged by a hinge 48 to the central portion 48*, that connects with the side rails, so that they will fold over toward the side rails, and

the legs are also hinged by hinges 4.9 to the central portion, but are arranged to swing upward toward each other under the ends of the bed. The tops are locked in vertical positions by sliding bolts 50 and keepers 51 and the legs and center portions by the bolts 52 and keepers 53.

The tilting head portion of the inner frame is adapted to raise a patient to an inclined or sitting position, the ratchet-wheel and pawl lockingit in any position it is raised to by its crank.

The lifting-sheet is adapted for surgical and other purposes and raises the hips of invalids above their heads, as shown by the incline ofthe dotted lines 54, which represents a plane of its raised position. A patient can also be raised bodily up above the bed and held substantially level by raising the head portion of the tilting frame and the end of the sheet at the same time. The sheet would then occupy a horizontal plane substantially like the dotted line 54;. An aperture 55 is made in the sheet near its free end for access through the sheet to its upper portion at this point. In Fig. 2 the position of the sheet is shown in dotted lines in its extended position hooked to the eyes of its frame. When not in use, it is rolled up in the roller and does not interfere with the bedding.

56 and 57 designate two arms that are pivotally attached by a screw 58 opposite one another to preferably the inside of the frame 6, although they could be attached, if preferred, to the side rails 2. A hub portion 59 is formed at the pivotal end in which there is a notch 60, into which fits the free end of the pawl 61, which is pivotally attached to the side of the frame by a screw 62. The pawl is adapted to lock the arm only in an upright position, as shown. The upper end of each arm is preferably widened out, and at each corner an upright pin 63 projects from them.

Upon these pins a band 64, of sheeting or fiexible material, is booked by rings -65, that are secured to the corners of the band. This arrangement enables the band to .be easily attached and removed from the pins of the arms. The arms and band are adapted for aleg-rest,

upon which an injuredleg may be raised above.

the bed for examination, dressing, or for rest. There may be several bands provided varying a few inches in length, so that different heights above the bed may be provided by.

using one that would just reach across or another that would sag, say, several inches. When not in use, the pawls can be raised out of the notches and the arms turned down in the direction of the arrow 66 and will rest on the shaft 29.

The bedstead may be all made of metal and be designed light of weight and portable. The arrows indicate the direction of the operative movements of the cranks, the head of the lifting-frame, and the sheet-lifting frame.

My invention is simple and can be applied to beds in use with but trifling expense and will add greatly to the comfort and ease of handling invalids.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-
