' 1 Claim.' (01. 5-85) I This invention relates to invalid lifting means, and has for one of its objects the production of afsimple and eificient means for facilitating the lifting of an invalid to and from a bed with a maximum amount of ease and a minimum amount of inconvenience to the invalid or patient.

, A further object of this invention is the production' of a simple and efiicientweight box which is carried by the main supporting shaft to act as a counterbalance for the weight of the patient or invalid carried on the stretcher.

Other objects and advantages of this invention will appear throughout the following specification and claim.

In the drawings'- Figure 1 is a perspective view of the lifting device and bed assembly;

Figure 2 is a perspective view of the lifting device with the bed removed;

Figure 3 is a perspective view of one of the standards and weight box supported thereby;

Figure 4 is a side elevational view of the weight box and a portion of the supporting standard therefor.

By referring to the drawings, it will be seen that the invalid-lifting means comprises a pair of spaced vertical standards I and I I. Each standard is supported upon a suitable base I2 having suitable casters I3 to facilitate moving of the device. The standards III and II are braced near the bottom by an intermediate bottom brace rail I4. A stretcher-supporting shaft I5 passes transversely through the upper ends of the standards I0 and I I, these upper ends constituting journals for the shaft I5. An enlarged gear I6 is secured near one end of the shaft I5 adjacent the standard I9 and a driving pinion I'I meshes with the A suitable operating crank I8 is secured to the gear I! to drive this gear. A removable stop pin 29 is carried by the standard I9 and engages the crank I8 to prevent the crank I8 from swinging in one direction and to hold the stretcher i 9 hereinafter described, in a selected elevated position. The bottom of the standard It which supports the gears I5 and I I and the adjoining end of the rail it are braced by an inclined brace M, as shown in Figures 1 and 2. A similar inclined brace 2I is located at the opposite end, as shown in Figure 2.

A pair of stretcher-suspending

straps

23 and 24 are anchored at one end to the shaft I5, as shown in Figural-g1 A buckle 25 of aconventional type is carriedf-by; each strap 22 and 2;; intermediate the ends thereof. The stretcher I9 preferably is formed of heavy cotton cloth, or other suitable flexible material and carries a pair of spaced stretcher poles 26 and.2I which pass through suitable casings which are formed .bystitchin'g the stretcher fabric along the side edges of the stretcher in the conventional manner.

Spreader boards 28 are fitted over the opposite ends of the

poles

26 and 21 to hold the poles in spaced relation and to provide a stretcher of. a

desired width to support the patient or invalid placed thereon. The stretcher I9 is provided with a longitudinal slit 29 to-facilitate the use of by coiling the

straps

23 and 24 around the shaft; I5 as the shaft I5 is rotated through the operation of .the crank I8. The stretcher I9 may be lowered by operating the crank I8 in the opposite d rection to unwind the straps. The removable pin 2! may be placed in a proper position to hold the crank a ainst swinging movement.

The st etcher I9 is ada ted to be lowered upon the bed B and the

poles

26 and 21 are pulled out from the casing 30 to permit the stretcher I9 to lie flat upon the bed B. The terminals of the

straps

23 and 24 may be detachably fastened around the standards I0 and II in any desired manner to provide loops 3| to hold the straps out of the way of the patient or attendant.

To provide a suitable counterbalance for the weight of the patient or invalid upon the stretcher I9, while raising and lowering the stretcher, there is provided a novel weight box 32. This box 32 comprises a casing having a vertical notch 33 formed upon the rear face thereof in which the standard II snugly fits. This box 32 is slidable vertically upon the standard II and is held against removal from the standard II by means of the straps or plates 34 which span the notch 33 and extend across the rear face 35 of the standard-I I. suspending straps 35 are anchored at their upper ends, as at 31, to the outer end 38 of theshaft I 5, and are adapted to be coiled about the shaft I5, as this shaft is rotated in one direction.

The lower ends 39 are clamped to the top of the box 32. by means of a cleat 49. Suitable bracing bolts '5! pass through the cleat II] and the top and bottom of the box 32, to brace the bottom of the; box and to assist in supporting the removable weight bars 42 which bars are adapted to be placed in the box 32. Any desired number of bars may be placed in the box 32 depending upon the weight which is to be carried by the stretcher. The box 32 is provided with a front door 43 which may be opened and closed for the purpose of inserting or removing the weights 42. This weight box 32 will greatly facilitate the raising and lowering of the stretcher l9 sincethe box will freely slide up and down upon the stand ard H, as the crank I8 is operated, and this box 32 will constitute a counterbalance for the stretcher and its occupant in the operation of the device.

An invalid or patient may be easily liftedv to and from the bed B by means of the stretcher I9 and the operating mechanism above described. The stretcher I9 is placed upon the bed B under the patient and the poles 2B and 21 are placed in the casings 30. The spreader boards or members 28 are placed over the ends of the

poles

26 and 21. and the straps 23: and Mare secured as shown in Figure 2. The crank I8 is operated to raise the stretcher l9 and the pin 20 is properly placed against the crank l8 to hold the stretcher IS in a set raised position. The bed B may be lifted away from the lifting device and the stretcher l9 may be manuallylifted and detached from the lifting device to remove'the occupant to a desired location. 7

, The patient or invalid may be placedupon the bed merely by reversing the operation after the bed 3' is placed in the position shown in Figure 1, and the stretcher I9 is lowered upon the bed B. After the patient or invalid is placed" upon the bed B, the bed may be lifted and removed away from the lifting device until it is again needed. Consequently, it is not necessary that the lifting device remain over the bed B while-'the'bed is being used, since the bed is entirely separate from the lifting device.

' Having described the invention, what is claimed as new is:

; An invalid lifting means of the class. described comprising a plurality of standards, a shaft journaled upon and extending between the standards, a stretcher, flexible means secured at one end to the shaft and being adapted to be wound upon said shaft as the shaft is rotated, means for rotating said shaft, the flexible means detachably engaging the stretcher for raising and lowering the stretcher as the shaft is rotated in a selected direction, means for locking the shaft against rotation to hold the stretcher in a selected elevated position, a counterbalance weight, weight-suspending flexible means suspending said weight from said shaft, said counterbalance weight comprising a hollow box, removable weight members carried within said box, said box having a vertical notch in its inner side nearest the stretcher, one of said standards being substantially square in cross-section and fitting vertion relative to the last mentioned standard, and.

anchoring means engaging the weight-suspending flexible means and extending through the bottom of said box.
