In the embodiment of the inventionillustrated, the stretcher includes a rectangular frame made of tubular metalmembers, each side of the frame being formed of three sections comprising a head 7 section 15, extending from the head end of the frame to the middle thereof, an intermediate section i6 extending from the middlejof the frame toa point substantially halfway between the middle and'foot end of the frame and a foot section 11, the contiguous ends of these sever-a1 7 sections having novel pivotal joints formed 7 thereon with means for looking or clamping them in any desired adjusted position. v The contiguous ends of the tubularjsectionjs l5, I6, and I! have inserts l8 fixed therein and provided with flattened ears l9 provided with interengaging, squared teeth 20, adapted to be engaged and locked in various adjusted positions to hold the frame sections in thedesired relative positions to support a patient; in -prone, reclining or sitting posit-ion. y i A'pivot boltrZl fextendsthrough;the-intermigaging e'ars I 9 of the joint an'cl a cam lever 22 is pi'ovidedu ponone end of the bolt and cooperates with the headildupon theioppos'ite end thereof :forlocking the joint inad'justedipo-sition as. shown in Figs. 1, 2,-1'and'8.

For the purpose 'of'iseparat'in'g the ears "H! to permitadjustmntrbf the .joint,.when the "cam lever 2 2I'is released, the opposed faces of the ears l9 are recessed as at '24 to house acoil spring 25 located around the bolt-2i and arranged to sepcam leyerwls'. released.

Thejform of-latch shown is 'illllls't'l'iated in detail Fig. 5 and cbns islisjo f 110llowccy lindric inserts 31 and '32, located, within the opposed ends of the tubular frame sections and handlesatthe corners of the frame in ourc prior .p'atentiare dispensed withsand the curved corners I26 and 25a of theframe'form adequate hand i tion of the spindle being screw threaded as 36 to engage the internal screw threads 31-inthe A hinge joint 33 is formed at the opposite end of the frame, preferably in one of the tubular foot sections 17 adjacent to the foot rail 28. When the latch '29 is operated tov unlock the sections of the head rail 30 the frame may be opened by means of the hing joint 38 in a manner and for a purpose to be later described. f

.A pair of align rods 39 maybe connected to the frame near the head end thereof, the outer ends at said rods bein rigidly connected to the side portions of the sections i5 while inner ends i of 'the-rods-are outturned as at 40 and rigidly connected to the head rail al en opposite sides of the center joint thereof. Similar rods 39 are I conhectedto the foot'e'nd'of't'he frame. v v

' Apairvof similar rectang'ular' panels 41 formed Of'Ca'nV'as orother suitable material, are attached to'the frame and form a'support' for the patient; Each of these panels is substantially one-half the widthof the frame and of:-a length substantially the same :as the frame and hasits outer edge connected to the adjacent side of. the frame as by i the spaced tubular portions 42 formed atthe edge of the panel'and locatedaround the adjacent side portion of the frame. These panels'are separable from eachi'other transversely ofi'th'eeframe and are provided with means for cconnecting'their end portions to the opposite sends 0f the frame This means is preferablyii-i *theiorm of adjustable straps 43, con- 1 'ne'cte'd' to"oppbsit"e ends of the panels G l as by rivets 2 and aloop'ed over the rods 39, buckles 4'5 ,being providedupon the straps for adjusting the tension upon the same.

These looped straps are slidable upon the rods 1 '39. asth'epanels' 4| are moved lateral-ly'of the frame when a patient is placed upon the stretcher; For "the purpose of supporting the me er edge portions or the panels "41 transverse lstra'p's :fltfare riveted/or otherwise connected to the undersuriface of each panel, each strap extending. across the other panel and provided at its end-with =a grommet or similar apertured device 41 adapted to bedet'achably engaged with pins 58 upon the "side portions of the -frame.

, lWhen these straps are connected as shown at Fig. 1 th'eyv 'serve to hold the panels in the position shown and prevent them from separating fi'omea'chbth'er through the longitudinal center of'the stretcher. 7 a v j c For the purpose of easilythreadingthe tra nsverse straps it beneath the body of the patient a ndattaching them to the pins 48-, a-finger pocket l-J, formed er leather, fa loric or other suitable material, may be attached to the outer "end of each strain is so that the same ay be guided beneath the body of the patientby inserting a finger inthe pocket. '7 I I, i

- With the stretcher in thee'xtend'ed position as shown in Figs. 1 and 2; the patient may be car- .ried in prone position. However, if desired either one or both of the hinged joints IQ on either side of the frame may be operated to adjust the sectidhs 1'5, re; ah-dlil 'of the frame relative to l'ea'dhbther'tb ca'r r'y th'e patient in a reclining or "s'itting position. i v I In Fig. 8, the frame is shown adjusted so that "I? a patient may 'be' cai-rie'd in a sitting position wheeled truck shown in Figs. 8 to 11,-inc1usiVe,

may be attached to the foot end of the stretcher.

As shown in Fig. 8 this truck is attached to the stretcher when adjusted for carrying the patient in a sitting position thus converting the stretcher into awheel chair. v

This truck comprises a frame 50 having depending U-shape brackets 5! at opposite ends Supporting an axel 52 upon which are journaled the rubber tired wheels 53. r

The truck is provided with two spring clamps 54 for engaging over the foot rail 28 and two spring clamps 55 for engaging over the sides of the frame sections I1 thus frictionally attaching the truck to the stretcher frame and providing for easily and readily attaching or detaching the truck as desired.

When it is necessary to use the stretcher to pickup a patient lying prone upon the ground,

or other horizontal surface, the straps 46 are disconnected from the pins 48, the latch 29 is released and the opposite sides of the frame are swung open upon the hinge joint 38. The end straps 43 are slidably moved outward upon the rods 39 permitting the panels 4| to be moved laterally of the frame. 4 i

The frame is then placed on the ground around the patient and moved back to closed position and locked by means of the latch 29. The straps 46 are then threaded beneath the patients body and engaged with the studs 48 and the patient will be supported entirely upon the panels '4! permitting the stretcher to be picked up by means of the frame and the patient carried thereon.

4. In a stretcher, a frame comprising a head section extending from the head end to approximately the middle of the frarnaan intermediate section and a foot section, means for pivotally connecting the contiguous ends of thesections together, means for adjustably holding the sections at different positions of adjustment and patient supporting panels carried by the frame, and a detachable wheeled truck connected to the foot end of the frame and curved clamping springs upon the truck for frictionally engaging over the foot end of the frame for detachably connecting the truck to the foot end of the frame.

5. In a stretcher, a frame comprisinga head section extending from the head end to approxi I mately the middle of the frame, an intermediate of the panels to the sides of the frame, a hinge joint at one end of the frame said hinge joint forming a means for laterally pivoting one side of the frame away from the other side of the frame, a separable joint at the other end of the frame and latch means for normally closing the separable joint.
