INVALID Application filed. April 18,
To all 40. 2am 3 6771611] concern:
B 't lrnown that l, ilosnrrr F. LA Views, :1 c of the United States, residing at Lau in the county of Jones and State of Mississippi, have invented new and useful Inipro ients in. Invalid Cauisrs, of which the following is a specification.
The object of this'invention is to provide a rolling ale, such as is commonly used in hospitals, with a means for sup porting thereabove a stretcher whereby a patient may be moved from his bed to an operating table, transferred with the stretcher from the rolling table on to the operating table, removed therefrom after the operation and again wheeled on the rolling table back to his bed, transferred from the rolling table with the stretcher on the bed, and wherein the frame for the stretcher is of such construction as to permit of the same being readily removed from the canvas body thereof so that the patient can lie in comfort thereon when arranged in his bed or whereby the canvas body of the stretcher may be employed as a rolling sheet for moving the patient therefrom on to the bed, the transfer of the patient being accomplished without necessitating the attendants laying hands on the patient.
To the attainment of the foregoing, and other objects which will present themselves as the nature of the invention is better understood, reference is to be had to the drawings which accompany and which form part of this application.
In the drawings Figure 1 is a side elevation showing the improvement attached to a wheeled or rlling hospital table.
Figure 2 is an end view.
Figure 3 is a top plan view.
Figure 4 is a sectional view approximately on the line dl of Figure 2.
Figure 5 is a sectional view approximately on the line 5-5 of Figure 2.
Figure 6 is a sectional view approximately on the line 6-6 of Figure 3, the stretcher being removed, and the parts being arranged to permit of the stretcher being moved off of the device on to an operating table or bed.
A wheeled'table, such as is ordinarily em ployed in hospitals and which is commonly known as a rolling'table is, in the drawings, indicatedby the numeral 1. These tables are usually employed for transferring patients from beds to an operating table and CARRIER.

for returning the patient from the table to thebed. In such instances it is necessary that the patient be handled by the attendants which is apt to interfere with the success of the operation and which is at times extremely painful to the patient.
In the present instance, I secure to the ends of the top 2 of the table 1, block members 3. Each of the members 3 is of a width approximately equalling that of the table top 2, each of the said members 3 having its inner edge formed with a reduced extension or web 4, the said webs having their upper edges at their corners flanged, as at 5 to provide jaws 5. Similar jaws 6 are formed on the webs below the jaws 5, the last mentioned jaws having threaded openings preferably surrounded by boss-lilre flanges, and through these openings there are screwed winged bolts 7 having swiveled heads 8 on the ends thereof, and these heads are designed for frictional contact with the under face of the top 2 to force the upper jaws 5 against the upper face of the said top, and consequently support the blocklilre members 3 on the rolling table.
For distinction the shoulders provided between the members 3 and the web extensions 4 thereof are indicated in the drawings by the numeral 9, and on each of these shoulders there rests a track. Each track comprises an inner section 10, and an outer section 11 connected to one end of the section by a rule joint hinge 12. Normally the section 11 is designed to be swung against the section 10, the shoulder 9 being of a width equalling the combined thickness of the track sections 10 and 11, and suitable means may be employed for holding the swinging section 11 latched against the fixed section 10. Both track sections 10 and 11 have their upper facesprovided with longitudinal grooves 13 that terminate a suitable distance away from the outer ends of the said sections, the said grooves designed to register when the sections 11 are swung to longitudinal alignment with the sections 10. hen in such positions the sections 10 and 11 are rigidly connected through the me is wholly received in the groove in the inner track section 10, and is moved partly out of the groove in the inner track section and into the groove in the swinging track section when both of said sections are in alignment. It is, of course, to be understood that the bolt contacts with the longi tudinal walls provided by the grooves to afford a rigid brace for the track sections.
The inner track sections 10, adjacent to theirends are provided with depending rods 17 that pass through guide openings in the block members 3. The inner track section is provided with a depending rack bar 18 that likewise passes through a suitable" opening in the block 3.
Each block-like member 3 has an opening or pocket communicating with the opening through which the rack 18 is received, and in each of these pockets there is journaled a cog wheel 19 in mesh with the teeth of the rack 18. The shaft for the cog wheels is indicated by the numeral 20 and has approximately centrally secured thereon a worm wheel 21'. The top 2 01 the rolling table is provided with depending members 22 having bearings 23 forthesha'ft 20, and it is between two of these members 22 that the worm'w'heel 21 is arranged; The worm wheel is engaged by a worm 24; the shaft of which being indicated by the numeral 25. The shaft" is provided at spaced intervals with annular depressions for the reception of sectional bearings26" provided upon the lower ends of hangers 27 seciired to the bottom of the table top'2. By thismeans the shaft 25 is held from longitudinal movement, and the outer end of the shaft has removably secured thereon a crank handle 28. It will be apparent that by turning the shaft 25 the worm will turn the worm wheel to' impart a rotary movement to the shaft 20 which, through the medium of the cog wheels 19 secured thereon and engaging the racks 18 will raise or lower the tracks, and incident to the coengagement of the worm wheel with the worm, the trackswiH be locked in eitherraise'd or lowered positions.
Designed to be arranged over and being of a" width equalling that of the inner track sections 10 are members which constitute what I will term a carriage. These members are each of a length equalling that of the track sections,- and are indicated, in the drawings; by the numeral 29. Each member 29has its loweriace provided with a pocket in which there is j'ournale'd a wheel or roller 30 of a widthto be snugly received in the groove 13 of both track sections. Each memberas'is provided with a square or rectan ular opening 31 adjacent'one of its ends, one of said; members being provided with a round o ening 32 adjacent its opposite end, the second member having: its: and. opposite that provided with the squared opening formed with a central slot the inner wall of which is 'ounded. Through the squa ed or the members constituting the there are inserted the reduced squared ends of a cross sectionally rounded bar 3 4 and through the round opening and through the slot there are inserted the roundee reduced ends of a second cross sectionally rounded bar 35. The bars 34: and provide the longitudinal members of a frame for a canvas stretcher e6, the ends of the said frame being provided by the niemliiers 29 which I have termed a carriage. The members 29 are provided with catch elements 37 engaged by coacting catch ele ments 38 on the ends 01 the fabric stretcher 36, one of the edges of the said stretcher being folded upon itself around the bar 34- and having coeng 111g catch elements 39. The opposite of the fabric stretcher is rolled around the bar 35 and is preferably secured to the said by catch. means 40. The trunnion on the bar 35 that projects through the slot is of greater length than the trunnion that extends through the round opening in the carriage frame for the stretcher, and this last mentioned trunnion, indicated for distinction by the numeral 41' has secured thereon a ratchet wheel provided with an operating handle 4-3. The ratchet wheel is engaged by deg l l pivotally secured upon the V rererred to end member of the stretcher carriage. By this means it will be noted that the stretcher may be tightly wound upon its supporting frame or carriage. Also, by an arrangement as above described it will be seen t nit when the canvas body of the stretcher is slaclrened that the elements constituting the frame or carriage therefor may be readily separated. The canvas body has its corners cutaway, as at 45 so that an attendant may grasp either the ends or sides of the stretcher carriage when it is desired to manually carry a patient on the stretcher and also when the stretcher carriage is to be directed on to the tracks of the device or oil" of said tracks.
The operation of the improvement may be briefly described as follows:
The rolling table is oi a height equal to or less than the bed in which e patient lies. The frame or carriage o' stretcher is removed therefrcrm and arranged on the bed, the patient being either rolled or placed thereon. The stretcher frame or carriage is then connected to the fabric body. The rolling table is wheeled against or near the bed stead. The outer sections of the track may be swung to align with the inner sections and locked together. The shait25 is operatedso that' the tracks will be in position to receive the wheels of the stretcher carriage thereon,- so that the attendants have merely to move the carriage in the ection of the rolling table. The patient is new wheeled adjacent to the operating table, and the shaft 25 is again rotated to elevate the tracks and the stretcher frame so that the former will be at a height equalling that of the operating table. The patient with the stretcher is again rolled off of the device on to the operating table. The patient rests on the stretcher during the operation, and there after is again moved with the stretcher on to the tracks carried by the rolling table and again wheeled to his bed and delivered thereon in a manner as above described. The frame or carriage is supported from the stretcher body, and the said body may serve as a sheet for the bed of the patient.
It is thought that the foregoing description, when taken in connection with the drawings will fully set forth the construction, operation and advantages of the improvement to those skilled in the art to which such inventions relate, it being noted that a hospital patient may be transferred from a bed to an operating table or to other parts of a hospital without his body being touched by the attendants so that pain and danger thus occasioned will be successfully overcome. The stretcher body, as previously stated, may be employed as a sheet for the body of the patient, as I, from experience, have found that such articles may be as readily cleaned as a linen sheet and are as comfortable to a patient. I have herein set forth a satisfactory and preferred embodiment of the improvement as it now appears to me, but it is to be understood that the nature of the invention is such as to render the same susceptible to all such changes and modifications as fall within the scope of what I claim.
