LlFTlNG-MACHINE OR INVALID-LIFTER.
SPECIFICATION forming part of Letters Patent No. 503,105, dated August 8, 1893.
Application filed June 20, 1890. Renewed December 31, 1892. Serial No. 456,880h. (No model.)
To all whom it may concern.-
Be it known that I, J OHN TINGLEY, a citizen of the United States, residing in the city of Brockton, county of Plymouth, State of Massachusetts, have invented a new and useful Device for Lifting Helpless or Invalid Persons, of which the following is a specification.
My invention relates to an original or improved device for lifting and moving helpless persons from bed to chair and return, with ease alike to the invalid and attendant. I attain these objects bythe construction of a device, made chiefly of'iron pipe, the mechanism of which is illustrated in the accompanying drawings.
Figure 1 represents a perspective view of the device embodying my invention; Fig. 2, a top plan view of the device parted at the upper girt; Fig. 3, a vertical section of one side of the device detached at the ends of the girts.
Similar letters refer to similar parts throughout the several views.
Fig. 1, A A are the vertical posts; B is the upper girt or cross tie attached to said posts by T. couplings a a. G is the lower girt attached to the bottom of the posts by the triple coupling 19 b. D D are arms attached by the third wing of the same at right angles with the post and the girt, extending out and constituting the base or feet of the device having toe and heel, with small wheels attached to the toes N and larger castors O at the heel. The feet D D are longer than the arms E E from which the weight is pendent, and form a sufiicient breadth of base to the machine to carry the pendent weight from the arms above. These feet are constructed with a view to occupying space. always vacant for them viz: under or outside of chairs and bed. By these means I obtain a fulcrum to my leverage on the floor, to lift upward in the air while the chair or bed intervenes between the arms above and the feet upon the floor. E E are arms attached by corner couplings to the top of the post extending out over and in the same direction as the feet, but not so far, and are adapted by special couplings having lugs c c, c 0 cast on their sides and drilled, forming bearings, to receive and operate the windlasses or crank shafts F Fto wind up the cords R R to lift the strap S. G G are vertical staffs attached to the upper girt, and support the arms H H, which are attached at right angles to the head of their staifs and are adapted by special form to screw on the tops of their staffs G Gsufficiently loose to be movable to the right or left and thus rendered adjustable. The upholstered wooden supports or crutch heads H, made circular to fit the arm pits, are attached-by invisible screws from the under side of the arms, said arms being hollow like the half of a split pipe, the two sides of which grow wider toward their base, and the cavity is fitted with half round wood. I is the semicircular wooden breast support, not upholstered in the drawing but designed to be in practice. -It is attached by brass tubes to the staffs G G made to slide up and down with the raising and lowering of the patient. This harmony of motion is secured by means of two small cords d (1 attached to the crank shafts or windlasses F F.
Fig. 2 is a section of the machine giving a clear top view showing parts not clear in Fig.
1. The brass tubes 6 e are here shown to have a long flange upon one side by which they secure the sliding tubes to the breast and back support I. The webbing strap J has an adjustable fastening at each end, thus confining the movements of the body to the steadiness of the breast support. The circle shows the common form of the waist of the human body, and that the strap J combined with the firm breast support becomes a support in all directions. The wires on m are designed to hold the windlasses at any point by simply hooking them together, as is easily done while the hands are on the cranks. They are sprung loosely in the grooves and play freely around the handles.
Fig. 3 is a side vertical section of Fig. 1, showing the wheel Nat the toe and caster O at the heel. P is aprojecting arm cast upon the corner coupling and thus supports the wheel in its compound motions.
The practical operation of my machine is as follows: Assuming that the patient is in bed, the attendant should place the lifter within convenient reach, then help the patient to a sitting position on the side of the bed, with feet off; the stirrup or lifting strap, which is detachable, should be laid back of the patient and drawn under by leaning the patient over first one side then the other to bring the strap to the right place. The lifter should now be run up in front of the bed, the feet going under, and the Windlass arms on each side, the machine against the bedstead. The patients body Will be close to the breast support; draw thebacksupportingbeltaround the patients bodygently tight, and hook; then hook the lifting belt to the Windlass cords; then with a crank in each hand turn both outwardly, fouror five turns being sufficient; the crutches will then enter the arm pits and the patient may be let down just enough to be comfortable. 'lhen hook the cranks together and move the patient Where desired, unhook the wires and let the patient gently down.
What I desire to claim and secure by Letters Patent is 1. A frame, the arms E supported thereon, Windlasses mounted on said arms, the lifting strap S having its ends connected with said Windlasses, and the crutch heads 11 on the frame, said parts being combined substantially as described.
2. A frame for supporting invalid lifting mechanism, consisting of vertical posts, feet extending from the base of the posts, and having side extensions forming heel and toes 4. A frame with a base, windlasses mounted on the upper part of said frame, a lifting strap connected with said Windlasses, an adjustable back and breast strap guided on said frame, and connected with said Windlasses, and crutch heads supported on the frame,
said parts being combined substantially as described, forming an improvement in devices for lifting helpless or invalid persons as stated.
5. A frame with a projecting base having a recessin the front thereof, a back and breast support guided on the said frame, and having mechanism for raising and lowering the same, said parts being com bined substantially as described.
