however, all have acommon fault which is that the person to be carried must be laid out flat and in a uniform reclining position. To force the body of an injured person terior of the body by movement of sharp fragments of fractured bones.
In view of the foregoing one of the objects .of my invention is to provide a stretcher which can beapplied to an injured person in the position in which he is found.
Another object is to provide a stretcher having a number a 2 I 11 Figure 5- is a midsectional elevational view of the .end portion or one of said transverse stretcher parts;

Another object is to provide a: means for-attaching a plurality of cross members to an injured person at .dif- 'ferent positions along his body, and then attaching a plurality of side members to'the ends of said cross members and at the. same time connecting the end-s of said side members and positioning them longitudinally in immobile relation. L I I p Still another object is to provide the transverse. members above mentioned with self-contained straps-which may be withdrawn and extended andapplied to the injured person quickly and easily and without the use of. tools or other apparatus. 7 j Y Still another object is to provide the partsabove. men.- tioned with means whereby they, can be easily stored in predetermined arranged positions so that they may be withdrawn quickly from a container in the manner in which they are to be applied to the injured person.
Other objects will appear hereinafter. v, j

The details of the parts inthe several transversestretcher parts are shown in Figures 3', 4, 5; ,6 and 7. These transverse members 1 10 are composed of a hollow metal "case 12 Which has an access plate 14 at the top held in place by a .numberof screws. Within the open partof the body 12 of each of these cross members thereis mechanismior holding and retracting web straps 15 and 16. These straps are each anchored within the openings in members 10- on cross pins 17' and 18, respectively.v The webbing then extends over crossrollers 19 and 20 which are held in extended position as shown in Figures 3 and 6 by springs Hand 22, 21' and 22. These springs are held in place by rods 23 and 24, 23' and 24' on which they ride. Theserods extend parallel to the length of each transverse member 10, and are secured in place in cavity 13 by insertion into the body 12 at the end of each cavity.
This structure permits the straps to be pulled'out from slots 25 and 26 on the top face of each member =12, and after the strap encloses a portion of the injured person they are hooked together by the compression clasp 27 on strap 15 which attaches to the free end 27a of strap 16.
At the ends of thebody 12 there are axially positioned pins 30 and 31. Each pin is provided with a slot '32 which receives a securing screw 33, which has a shank to slidably fitin slot 32 and a threaded lower end 34 which is screwed into the body 12 to hold it in place. A spring 35 is placed in each axially extending bore 36 and presses the pin body outward. At the outer end or each of these pins there are slots 37 and 38 through'which the hooks 39 and-40 extendf These hooks are' hinged together'atdz and provided with springs 43 operating around the hinge pin 42 to urge each of the hooks outward through their respective slots. There is a space between each end of body 12 and the inner face of each book 39. and 40m accommodate the thickness of the longitudinal stretcher members 50. which will be hereinafter explained in detail.
'Each of the transverse members is the same and may be stored one upon the other, as shown particularly in FigurelO. i
The longitudinal members 50 are made of flat aluminum sheets approximately thick and are lens shaped. At each end there are connecting devices so that each longitudinal piece may be connected to the next and the angle that each piece bears to the adjacent piece may be adjusted and held. I To do this I provide a male connecting disk 55 secured to oneend of each longitudinal element 50, by a flat head screw 57. The male connecting disk 55 fits into a female connecting ring 60 welded to the adjacent end of the next adjoining longitudinal member. These connecting parts are pivotally joined by shouldered flat head screws 57. Spring held locking pins 62 operate in guide blocks 63 and extend into any one of several radially extending and peripherally spaced locking holes 64 in the female ring member 60.
Each longitudinal member has a hand clearance hole 65 in its central portion and four pin receiving holes 66. These .are positioned adjacent the side edges of the body 50 and symmetrically on each side of its center and are made of a size sufficient to receive the pins 30 and 31 on the transverse members. 7
It will benoted that after any one of the transverse members is inserted in any one of the holes 66 the hooks 39 and 40 snap out from their compressed position within each of the pins and engage the outer face of the transverse member immediately adjacent to the hole 66 in which the pin is inserted. In this way each end pin of the transverse member is locked into any one of the holes, such as 66, in the transverse member.
In assembling the stretcher and confining the body A of an injured person thereon several of the transverse members are. applied to the body A, as shown in Figure 12. That is, a transverse member 10 is placed behind the head of the body A and the straps 16 and 17 withdrawn from the interior of the transverse member 10 as shown; these straps are then brought around the head B as indicated in Figure 12 and the ends of the straps secured by latching the end 27 of strap into. the clasp 27a of strap 16.
. A second transverse member 10 is then placed in back of the shoulders of the body A, as shown in Figure 12, and the straps withdrawn and clamped together, as shown, over the shoulders of the body. Similarly, difierent transverse members are placed on the .body A in whatever position it may be found after an accident. When the necessary transverse members are in position then the longitudinal members are attached to the pins 30 on the right hand ends of transverse members 10 and longitudinal members are then attached to the pins 31 on the left ends of all transverse members. The transverse members are located and adjusted so that the pins will fit into any one of the four holes 66 in the transverse members. In doing this care is taken to see that the transverse members are parallel and extend at right angles to the length of the body A.
As the longitudinal members are applied they are set with the elements 10 at such angles relative to each other to accommodate the positioning of the pins at the ends of the transverse members. When the correct angle is ascertained they are locked in place by the pins 62. The pins hold their position by reason of the springs 62a. When all the transverse members have been joined by aflixing and adjusting the longitudinal members the body is in the conditon shown in Figure 13 and is ready to be moved as indicated in Figure 14. It will be noted that the legs of the body bear the same relation to the torso as when the body was first discovered after the accident in Figure 11. Therefore, injury both internal and external is minimized during the process of attaching the stretcher parts and in moving the body to a truck such as D.
A body A secured in and on the composite stretcher E may also be lifted out of a mine shaft or the like by the attachment of a cord or rope' yoke F as shown in Figure 15. Optionally the body maybe held straight with the longitudinal members 50 longitudinally aligned with each other, as shown in Figure 16. In this case the body is maintained straight and may be supported on the top edges of the backs of seats G of any automotive vehicle.
In Figure 17 the elements 10 are set at the joints so that E has an arched aspect. The body A is thus held in a position considered beneficial for certain spinal inuries.
The Figures 11 through 17 are to be considered semidiagrammatic and are added herewith to illustrate some of the varied uses to which the composite stretcher E may be put.
In Figure 10 a case is shown in which the several parts of the stretcher may be conveniently placed. Thus, in the upper part A--A the stretcher members are placed because they are the first ones needed when an injured person is to be accommodated. In a compartment B-B the other, such as the side elements 50, are placed because they are needed after the transverse members are in place. Two other compartments B'B' are added to provide space for various accessories needed.
