SPECIFICATION formingpart of Letters Patent No. 726,472, dated April 28, 1903.
Application filed November 5, 1901- Serial No. 81,197. N m l- To ctZZ whom it may concern:
Be it known that I, JOHN B. SMITH, a citizen of the United States, residing at Des Moines, in the county of Folk and State of Iowa, have invented certain new and useful Improvements in Hospital-Beds, of which the following is a specification.
The object of my invention is to provide a hospital-bed of simple, durable, and inexpensive construction which is as comfortable as the ordinary bed, but has a simple device for lowering the mattress away from the bed, leaving the patient who has been lying on the bed comfortably lying on cross-straps, which are attached at each end to the side rails of the bed, without changing his position.
A further object of my invention is to provide a hospital-bed of light and durable material which has detachably connected with it a removable standard of simple and durable construction, to which hooks can be readily attached -to or detached from, and which can be taken apart and stored in a minimum amount of space when desired by the operator.
A further object is to provide a hospitalbed which can be used with the detachable mattress-bearing frame or without it.
A further object is to provide a hospitalbed of suitable material which shall be sanitary in every particular and which can be easily taken apart and cleansed when desired.
My invention consists in certain details in the construction, arrangement, and combination of the various parts of the device whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claim, and illustrated in the accompanying drawings, in which Figure 1 is a plan View of the entire bed with the posts cut away. Fig. 2 is a side elevation of the bed with the top portion of the posts cut away and the mattress bearing frame shown in dotted lines in its lowered position. Fig. 3 is a cross-sectional view of one of the side rails of the bed, showing the means for holding the cross-straps at their end portions. Fig. 4 is a detail view of the end portion of one of the side rails of the bed, showing the ratchet-wheel and catch for holding the mattress-bearin g frame in the desired position against or away from the bed. and means for attaching the bed-frame to the mattress-bearing frame. Fig. 5 is a detail View of the opposite end of the side rails shown in Fig. 4 and shows the means for attaching the mattress-bearing frame to the strap which is a part of the mechanism for raising and lowering it. Fig. 6 is a perspective view of the crank to be used in turning the ratchet-bearing shaft.
Referring to the accompanying drawings, I have used the reference-numeral 10 to indicate the frame of the bed proper, comprising the side rails 11 and the end rails 12 and the upright posts 13 and the curved corner-pieces 13, attached to the posts approximately halfway between the top and bottom of said posts and designed to act as a connecting-piece between the end rails and the side rails, all of the rails, upright posts, and collarpieces being of metal and hollow in their central portions. On the outside of each of the side rails I have attached the thin metal strips 14.'by means of the screws 15. The washers 16 are placed between the metal strips and the side rails placed equal distances apart to form the openings 17, each of said openings being the same size. Across the bed and extending from one side rail 11 to the other and an'equal distance apart are the straps 18, the end portions of which are folded against the body portion and are fixed in that position to form the loops 19, the said loops being pushed through the openings 17 between the metal strips and the side rail of each side of the bed-frame 10 in such a. Way that these loops will extend partially below the metal strips 14 and admit the pins 20, which are of sufiiicient length to have their end portions engage the washers 16 and hold the said straps in position when the pins are through said loops.
Rotatably mounted in the bed-frame lO'are the shafts 21 and 22, parallel to the end rails, each having their end. portions in that portion of the corner-pieces 13 close to the side rails 11. The shaft 22 has a square end 23 thereon and is a little longer than the shaft 21, and is thus made to extend through one of the corner-pieces and outside thereof to receive. the crank 24., said crank being designed to assist the operator in operating the device. Mounted on the shaft 22, near the square end thereof and inside of the cornerpieces 13, is a ratchet-wheel 25, the ratchets on said wheel being designed to engage one end of the catch 26, the opposite end of said catch being attached by the pivot 27 to the upper side of the end rail 12 nearest it. Near each end of the shaft 22 is fixed the metal loop 28. To each of these loops 28 is attached by one end thereof a band 29, which is passed under the shaft 22 and extends the entire length of the bed and is passed over the shaft 21 until the end thereof reaches the floor on which the bed-frame rests, these bands 29 having the hooks 30 attached at the opposite end from the one attached to the.
loops 28. To each of said loops 28 are also attached by one end the bands 31, having the hooks 32 at the other end of them, and are of sufficient length to reach the floor from the shaft 22.
I have also provided a mattress-bearing frame 33, comprising the tubular side rails 34, the tubular end rails 35, and the legs 36, which are firmly attached to the side rails 34, said mattress-bearing frame 33 being designed to fit inside of the bed-frame and to come against the straps 18 when inside the frame and to be held in that position for the patient to lie on when the straps are not holding his weight. Near each end of the end rails of the mattress-bearing frame I have attached the hooks 37, with the eyelets 38 in them, these eyelets being designed to receive the hooks on the ends of the bands 29 and 30 when it is desired to draw the mattress-bearing frame against the straps in the bed proper. These hooks are unhooked when it is desired to remove the mattress-bearing frame from beneath the straps in the bed-frame proper. I have provided two openings 40 on the inside portion of each of the tubular end rails 35, extending from the exterior surface of said tubular end rails to the interior portion of them. These openings are designed to receive the ends of the hooks 37 which are away from the eyelets 38. On the mattressbearing frame is an ordinary mattress 39.
In practical use, and assuming that the mattress-bearing frame 33 stands upon its legs on the floor, the mattress 39 is placed thereon, and the cross-straps 18 of the frame are placed across the said frame in position for use by putting the pins through the loops 19 in the ends of the cross-straps 18. When it is desired to raise the mattress bearing frame to its position inside the frame 10 and against the cross-straps 18, the hooks 30 of the bands 29 are slipped into the eyelets in the hooks 37, and the hooks 32 are slipped into the eyelets 38, which are attached to the opposite end of the mattress-bearing frame, the bands 29 and 31 being let outto their full extent. The crank 24 is then put onto the square end 23 of the shaft 22, and by turning the crank 24 the mattress-bearing frame is raised to its position against the straps 18, and the catch 26 engages one of the ratchets on the ratchet-wheel and holds the mattress-bearing frame in the desired position against the cross-straps 18. Assuming that it is desired to raise the patient and have him lie upon the cross-straps, then the bed is lowered by raising the catch 26 and controlling the downward movement of the mattress-bear ing frame by the crank 24:, and by unfastening the hooks and 32 the mattress-bearing frame can be taken from beneath the bedframe 10 and placed entirely out of the way. Then if it is desired to obtain access to any part of the patients body any one of the cross-straps 18 may be removed by taking out the pins 20, which are through the loops 19 in each end thereof. The cross-strap which has just been removed can be replaced by putting the pin in position from which it was taken and the cross-strap in its position. The operator can also lower away the mattressbearing frame and take it to pieces readily and store it. He can then take the mattress and use it as a part of the bed-frame proper without the mattress-bearing frame by simply placing this mattress on top of the crossstraps 18. The bed can be easily taken to pieces and thoroughly cleansed at any time on account of the metal substances forming .the rails, posts, and corner-pieces, and it will be very light on account of these portions of the bed being of hollow construction. This bed can be easily moved from one place to another on account of the small amount of room taken by it when the portions of the bed are taken apart.
Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States therefor, is-
In a device of the class described, the combination of two hollow side rails, of two hol low end rails, curved corner-pieces for connecting said side pieces with said end pieces, a shaft rotatably mounted between the two corner-pieces near the head of the frame, a shaft rotatably mounted between the cornerpieces near the foot of the frame, a pawl pivoted to the corner-piece nearest the ratchetwheel for engaging the ratchets of said wheel and holding said ratchet-wheelin position rel= ative to the frame, a mattress-bearing frame made of hollow tubing having side rails and two end rails, curved metal corners for connecting said side rails to said end rails, said latter end rails having two openings extending from the exterior of the tubing into the interior thereof, said openings being made in the side of the tubing nearest the mattressbearing portion of the frame, two hooks extending partially around each of said end rails of the mattress-bearing frame, projections on said hooks entering said openings for holding the hook firmly in position relameans for turning the shaft at the head of tive to the end rails of the mattress-bearing the frame for raising and lowering the matframe, an eyelet at the upper portion of each tress-bearing frame, for the purposes stated. 10
