MORRIS V. HUBBARD, OF SAN JOSE, CALIFORNIA.
Specification of Letters Patent.
Patented Dec.. 3, 191..
Application led May 27, 1918. Serial No. 236,836.
To all whom t may concern Be it known that I, MORRIS V. HUBBARD, a citizen of the United States, and resident of San Jose, in the county of Santa Clara and State of California, have invented certain new and useful Improvements in Stretchers,
of which the following is a specification.
One object of my invention is to provide a device of the character indicated that can be quickly and easily separated on a median line so that a patient may be deposited upon a bed or operating table witha minimum amount of disturbance. Other objects of my invention are to provide a devicel ofthe character indicated, 1st, that is provided with a resilien'tly mounted separable canvas member; 2nd, that can be quickly and easily taken apart and reassembled; 3rd, that is provided with collapsible handles; 4th, that can be `folded up into a compact bundle; 5th, that is economical tovmanufacture, substantial and practical.
With these and'other objects in-view my invention consists of the novel and useful provision, formation, construction, combination and relative arrangement of parts, members and features, all as hereinafter described, shown in the'drawings and finally pointed out in the claims.
In the drawings Figure 1 is a plan view `of my improved stretcher. Fig. 2 is a side elevation of the device as shown in Fig. 1. Fig, 3 is an enlarged longitudinal sectional view through the central coupling member, parts broken away. Fig. 4 is an enlarged cross sectional view on line 4-4 of Fig. 1. Fig. 5 is a plan view of one set of spacing members in an operative position and adjacent portions of the stretcher proper. Fig. 6 is an.- inner side elevation of one side member, part broken away. Fig. 7 is a detail illustration of the lock for the spacing device.
Similar characters of reference refer to similar parts throughout the several views. ln the following description one half of the device is described in detail and the corresponding parts in the other half are indicated by similar numerals followed by the letter a.
Referring now more particularlyto the drawings, one half of the device consists of a side pole 1 having plates 2 positioned upon either end, each 3 formed on each 4 provided near side thereof, and an orifice its inner edge. Adjacent plate 2 having a shoulder each plate 2, and on either side of pole 1, are inks 5 pivotally mounted on bolt 6 passing through pole 1. Each pair of links 5 has a handle 7 pivotally connected thereto by pivots 8, the handle 7, links 5 and plate .being so proportioned and so positioned wlth relation to each other that when the handle 7 issturned downwardly into the positlon B links 5 will engage shoulders 3 on plate 2 and thereby be held from further rotation while handle 7 may be swung around on pivots 8 into the position C. A portion of the under side of4 pole 1 is removed as at 9 to form a recess or pocket for handle 7 when it is thus revolved into position C. v
Hooked into orifices 4 and into eyes 10 spaced along the inner side of pole l, are a number of springs 1l. At 12 is indicated a ca nvas sheethaving a rod 13 positloned adjacent its outer .and longeredge and around which are hooked. Along the inner edge of sheet 12 are spaced a number of canvasl loops 14, the same alternating with similar loops 14a spaced along the inner edge of sheet 12B. At 15 is indicated a couplingmemberpositioned in loop 16 attached to sheet 12, and threaded as at 17 and 18 respectively to receive the threaded ends of rods 19 and 20. The rods 19 and 20 are provided with suitable handles as 21 through the alternating loops 14 and 14a and into coupling 15 securely fasten the two halves of the device together. Additional handles 23 are secured to the outer side of pole 1.
The spacing devices, one at each end of the stretcher, are identical in construction and therefore but one is described. Pivoted to pole 1 near handle 7'is a bar 24 having a notch 25 formed in its inner edge and at a point that is midway between poles 1 and l*l when the spacing device is in an operative position. The free end of bar "24 is and 22 and when passed the several springs 11 bent downwardly and inwardly to form a out and bars 24: and 30 swung out into such a position as indicated in dotted lines at 24;a
and 30a in Fig. 5. Shoving the two bars forwardly forces pin 31 into notch 25, causes hook 32 to engage bar 24 and hook to engage bar 30, and pin 28 to engage orifice 33 thereby securely locking the parts in the positionshown. They patient is now placed upon the stretcher in the usual manner. The stretcher with the patient upon 1t may now ,loe placed upon a table, or by folding handles 7 and 7a inwardly into the position C it may be placed directlyupon a bed of standard length.
The stretcher lmay now be removed with a minimum amount of discomfort to the patient by simply unscrewing and removing' rods 19 and 20, thus permitting the two halves of the stretcher to be withdrawn without removing the patient. By realining loops 14.- and 14 and replacing rods'19 and 20 and screwing the same into coupling 115' and relooking the spacing members, the stretcher is again rendered 'ready for use,
or the spacing devices may be folded back into their respective recesses and the whole device rolled up until again needed.l If the canvas 12 becomes soiled it may -be readily removed for washing by removing rods 19 and 20 and 13 and unhooking springs .11. The extreme ends of canvas' 12 are supported by buttoned straps asf/at 85.
Additional comfort is secured to the patient by the'use of springs 11 because these springs absorb a great deal of the vibration incident to moving, especially if the patient is to be carried some distance as in an amf bulance.
While I have herein shown and described one specific from of my invention, it is understood that changes in form and construction may be made within the scope of the appended claims.
