5 Claims.

This invention relates to stretchers or carriers for use in transporting patients, or wounded, fractured, or other disabled persons.

' An object of the invention is to provide an improved stretcher consisting of a body formed of canvas or other suitable fabric which is braced by a plurality of longitudinally extending slats constructed and so arranged therein that the ers are arranged in longitudinal pockets formed in the body of the stretcher.

With the foregoing and other objects and advantages in view, the invention consists in the preferred construction and arrangement of the several parts which will be hereinafter fully described and claimed.

- In the accompanying drawings:

Fig. 1 is a bottom plan view of a stretcher constructed-"according to the present invention;

Fig. 2 is a transverse section taken on the line 2--2 of Fig. 1;

Fig. '3 is a longitudinal section taken on the line 33 of Fig. 1;

Fig. 4 is a sectional view of the parts shown I "in Fig. 3 in folded position;

Fig. 5 is a longitudinal section taken on the line 5-5 of Fig. 1;

Fig. 6 is an enlarged plan view of a portion of the structure shown in Fig. 1;

Fig. '7 is a longitudinal section taken on the line 'I-I of Fig. 1; and

Fig. 8 is a view of the stretcher folded. Referring to the drawings, the main body of the stretcher consists of a rectangular piece of canvas or other suitable fabric II, which forms the upper face of th stretcher when the device is laid upon the ground, floor or other supporting means to receive the body of a person.

Forming the other side or bottom of the stretcher are two pieces of fabric I2 and I3.

The pieces I2 and I3 are assembled upon the single piece of fabric II in the manner shown in Fig. 1 so that the edges of the pieces I2 and I3 at the transverse center of the device are spaced 2. suitable distance apart (see Fig. 6).

Preferably all pieces of fabric used in the construction of the improved stretcher are formed from heavy tightly woven canvas of good quality and possessing considerablestrength.

The three pieces of fabric II, l2 and I3 are stitched together around the periphery of the device by stitches, indicated at I4, Fig. 1.

A handle I 5 is secured to each corner, whereby the stretcher and its occupant can be conveniently carried. The handles may be formed of any suitable material, arranged in U-shape and having their free ends riveted or otherwise secured to the body of the stretcher, as indicated at l6, Fig. 1.

A suitable number of straps are secured to one longitudinal edge of the stretcher, and a corresponding number ofbuckles I8 are secured to the other longitudinal edge of the stretcher. These straps I! and their'buckles l8 may be used for the purpose of fastening a person in position on the device.

Extending transversely across the two pieces II and I2 and arranged a suitable distance from the end of the stretcher, is a row of stitches I9.

Also extending transversely across the two pieces II and I3 and arranged a suitable distance from the other end of the stretcher, is a row of stitches 20, similar to the stitches I9.

Formed longitudinally in the body of the device and extending from a point adjacent to the transverse row of stitches I9 at one end, to a point adjacent to the transverse row of stitches 20 at the other end, is a series of stitches 2| which are connected at their ends, in the manner shown in Fig. 1, by transverse rows of stitches 22 and 23.

The stitches 2t, 22 and 23 are so arranged that a series of pockets 24 are formed longitudinally in the section of the device composed of the pieces II and I2, and a second series of pockets 25 are formed longitudinally in the section of the device composed of the pieces II and I3, said pockets 24 being arranged in alinement with the pockets 25, respectively. 7

Since the adjoining transverse edges of the pieces I2 and I3 are spaced apart a suitable distance, between and at each side of the pockets 24, 25 the edge portionsof the pieces I2 and I3 are secured to the piece II, by transverse rows of stitches 26, 21, respectively, as shown in Figs. 1 and 5.

Supported by the inner face of the piece I I and having a width greater than the distance or space between the adjacent transverse edge portions of the two pieces I2 and I3, is a transverse strip of fabric 28. This piece of fabric 28 is secured to the pieces I I, I2 and I3, bystitches 40 and 4|,

.as shown in Fig. 3. The purpose of the fabric tucked in between the two-folded portions.

pockets 24, 25, respectively. Each slat preferably consists of two pieces 29, 30, the pieces 29 being disposed in the pockets 24, and the pieces 30 being disposed in the pockets 25, respectively.

The slats are preferably constructed of strongpieces of wood having rounded longitudinal edges 3 I, as shown in Fig. 2, on their upperedges.

The abutting or adjacent ends of each alined pair of slats 29, 30, are pivotally connected together by means of a hinge 32, arranged in the -manner shown best in Figs. 3 and 6.

The hems at theinner transverse edges of the pieces [2, l3 are preferably secured by means of the rows of stitches 36, 31, respectively.

The slats'function as means for stiffening the device in a longitudinal direction, and since the ends of said slatsterminate at a distance from the ends of the device, at one end there is provided a flexible headpiece 38 and at the other -end there isa-flexiblefoot piece 39.

, Since the several pockets 24, 25 are many" connected by the intermediate plies of fabric, ,the .bodyof the stretcher may be flexed in a transverse direction. In this way a bed or support, is provided on, which a person may be prop- :erly sustained or carried ;When not ,in use, the stretcher may be folded compactly, as shown in Fig. 8, so as to occupy a very small space. For example, astretcher constructed accordingto the present invention whenopen, as shown in Fig. 1, may be six feet six inches in length and twenty-eight inches in width. When folded, as shown in Fig. 8, the same stretcher is only thirty inches long and eight inches in width.

In order to. fold the stretcher, the device is lflrst placed upon a support with the hinged side --of the slats, or theb'ottom side of the device shown intFig. 1, up. The two end sections 38 and 39 -"are :first folded inwardlyalong the lines of the .stitches 22 and 23, respectively. The device is then .folded along the pivot line of the hinges 32 .so'th'at one half lies upon the other half, as

:shbwn fragmentarily in Fig. 4. The buckles I8 and the centrally disposed strap I! may next be r The device is then rolled or folded into the form shown in Fig. 8, and the two end straps I! wrapped around the bundle and tied so as to securely fastenthe bundle in the manner clearly shown in Fig. 8. Due to the disposition ofthe handles [5,

,when the stretcher is folded'into a bundle in the -manner'descri-bed, two of the handles will be conveniently disposed, as shown in Fig. 8, for carrying the device, or if desired the bundle may '-be easily carried by encircling the same with an arm of the person.
