SPECIFICATION forming part of Letters Patent No. 455,778, dated J uly 14, 1891. Application filed November 25,1890. Serial No. 372,596. (No model.)

To all whom it may concern.-

Be it known that 1, MICHAEL TELL, a subject of the Emperor of Austria, residing at Vienna, in the Province of Lower Austria, in the Empire of Austria -Hungary, have invented certain new and useful Improvements in Litters for the Infirm and \Vounded; and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompany ing drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

The invention relates to that class of handconveyances for the sick and wounded known as stretchers, and has for its objecta con- 'struction whereby such hand-conveyances are not only rendered more efficient in use, but more comfortable to the person carried thereon, and whereby said conveyance is adapted for use under conditions that would preclude the use of a hand-conveyance of this class as heretofore constructed.

My invention comprises a stretcher constructed of a material more rigid than the textile fabric heretofore employed andadapted to be folded so that it may be carried like a knapsack. It also comprises means combined with the stretcher whereby the person may be carried in a sitting posture; also, means whereby the stretcher may be readily secured to a wheeled truck and propelled either like a barrow or a two-wheeled vehicle; also, means whereby the .stretcher may be used for the lowering of a sick or wounded person from the upper stories of a building not provided with an elevator, or as a firees-' cape in case of egress from a building being cut off by fire; also, means whereby the patient may be thoroughly protected against the inclemency of the weather or agalnst the glaring light or shaded from the sun; also, means whereby the legs of the patient may assumedifferent positions relatively to each other, as will now be fully described, reference being had to the accompanylng drawings, in which 7 Figure 1 is a perspective view of the stretcher proper without the carrier-bars.

Fig. 16 is a longitudinal section, and Fig. 17 a transverse section, of a sled and means for securingthe stretcher thereto. Fig. 18 is a detail view. Figs. 19, 20, and 21 are sectional views illustrating the mode of applying the stretcher to per-ambulators In the construction of the stretcher, instead of using a textile material, as has generally been the case heretofore,I em ploya material that is, although more or less elastic, yet sufficientty rigid to avoid the use of transverse stretchersas in the case of a textile material. To this end the stretcher is constructed of interwoven split cane, as shown in Fig. 4. which is nearly as light as the heavy canvas usually employed, and in order to adapt such a stretcherto be folded into a small bundle, and also to adapt the stretcher to be adjusted to variou's positions, I construct the same insections.

As shown in Fig. 1, the stretcher is composed of six sections A, B, O, D, E, and F, connected together by hinge or flexible joints, preferably the latter, said joints being made of a strong textile material, as shown at a, b, c, and (Z,

Figs. 1 and 5. The head-scctionA is provided on each side with a loop a, of leather or other flexible materiahwith two buckles a a on its under side near the outer edge, with two loops or rings a a, with a series of strap slots or eyes a around its edges, and with a strap a at the hinge-joint a, at which point, on the back of the section,are also secured two button flaps or flies a a The section B is provided on each side with a guard projection or wall 6 12 of the same material as the stretcher, said guards tapering toward the head-section A and having formed therein slots or eyes If, and are provided with buckles b and with buttons b Z9 Z7 Z7 As shown in Fig. 1, the section B, which I may term the-shouldersection, is slightly wider than the remaining sections, and has formed therein on each side, inside of the guards b I), a strap-slot for the passage ofthe straps 17, each of which has a safety-hook 1. On the back of section B are secured threestrap-loops 19 one about centrally of the section near the flexible joint a and the other two near the edges at the flexible joint I), at which point are also secured two strap-loops 2,and to the front of said section, near the joints a b, are secured four small straps h, each of the sections 0, D, and E beinglikewise provided with four such straps it. Finally, said section B is provided on opposite sides with two stretcher-bar loops 1) b The section 0 has also on each side two stretcher-bar loops 0 and two angle-straps 0 provided with eyes 0 and to each stretcher-bar loop 0, at the joint 0, is secured a buckle a The sections D and E, instead of having stretcher-bar loops like sections A, B, and C, have straps cl e respectively, section D having four such straps d, two on each side, .while section E has but one strap e on each side,said straps serving also for purposes other than merely connecting the stretcherbars to said sections to prevent the stretcher from slipping on the bars.

The section D is further provided with a strap (1 on each side, a portion d of which is stiifened by the insertion of a steel plate.

The section E has at the joint 6 two buckles e and on its under side at the jointd three buttons 6 while the section F has near its outer edge two buckles f, facing inwardly, and on each side a buckle fifacing outwardly.

If desired, the stretcher-sections may be stifiened by interweaving steel stiffeners 'r, eitherlongitudinallyor transversely, and this I prefer for ordinary ambulance service.

When the stretcher is in use, a pillow A Fig. 2, provided near one edge with hooks and near the other with a buckle, is hooked to the loops or eyes a and secured by straps 6012.

To protect the patient or wounded against the glaring light or the heat of the sun, I providea hoodA, that is constructed somewhat like a. folding buggy-top or perambulatorhood, (see Fig. 6,) and has along its edges straps and buckles a a said straps being passed through the eyes a Fig. 1, to secure the hood A in place. (See also Fig. 8.) To the front bow or rib of the hood is secured a buckle a,

to which the upper end of the cover B is hooked, said cover B being provided with a hook b Fig. 6, and the hood has a curtain m to the inside of which are secured hooks a for the reception of loops 1) on said cover B to hold the same in the position shown in Fig. 6, the curtain a overlapping the upper edge of the cover B to exclude rain and wind.

To provide for admission of air under the hood, it has on each side an opening provided with a flap or cover a If the weather is such as not to require the complete covering of the patient or wounded individual, the curtain 01, may be thrown back over the hood, and when the latter is not in use it is folded down and firmly strapped down by the strap (i which is first unbuckled and then buckled to the buckle a as shown in Fig. '2.

The cover 13, which is preferably of waterproof material, as well as the hood A, has straps and buckles 5 (shown in dotted lines, Fig. 6,).that are passed through the eyes 19 in the guards b 17, whereby the said cover is secured to section B of the stretcher, to which the patient or wounded may be firmly strapped by means of the strap 5 and buckle 5 secured to the guards b 5 respectively, to prevent him from falling out or from slipping upor down when the-stretcheris carried down a declivity or steep incline. The cover B has a series of button-holes that button over the buttons 19 b on the guards b b, respectively, the buttons 1) b and Z9 19 also serving to secure the curtain a of the hood A, which is provided with suitable button-holes for this purpose,as shown in Fig. 6. The cover Bis further secured at the foot end by buttoning the buttons e of section E, which section is turned up when the stretcher is in use and secured in position by means of the straps d the stiffened portion d of which performs the function of a brace, said straps d being buckled to buckles e of section E, while section F is or may be turned down on section E, as shown in said Fig. 6, and secured in place by means of the straps e buckled to buckles f of section F. This last-named section is provided for the purpose of lengthening the stretcher for a person above the normal size, and when not in use serves asa stiffeningbrace to the foot-section E.

The stretcher may be folded in such a manner as to be carried on the back like a knapsack, and this feature of my invention is considered a very valuable one in view'of the ease of transportation, and in view of the fact that in war circumstances arise when a vehicle or even a pack-animal cannot be brought to the field of battle, and when a stretcher as heretofore constructed cannot be carried by hand except with the greatest difficulty.

The folding is effected as follows: The cover B is detached from its fastenings,rolled up, and by means of straps b Figs. 2, 6, and 7, is buckled to buckles b on the outside of the guard b Fig. 2. back and secured, as hereinbefore described, by means of strap a and buckle at The pil- ICC The hood A is folded low A is detached and hooked to eyes 2 2 on back of section B and secured by a strap 3 on strap-loop Z2 Figs. 1 and 3. The sectionsE and F folded, as shown in Figs. 6 and 13, are now turned on the back of section 0, and section 0, with the remaining sections on the back thereof, is folded onto section B, so that all of the stretcher-sections except the head-section A will lie on B between the guards b b. The head-section A is now turned down over the sections inclosed in B and serves as a cover and is secured by means of the straps c 011 the back of C and the buckles d on the outer edge of the back of A. (Shown in dotted lines in Fig. 1.) Finally,shoulder-straps B for carrying the folded stretcher, are passed through the hinged loops F1 on the back of section B. In order to avoid the use of separate shoulder-straps for carrying the stretcher when in use and when folded, the said straps 13 are provided with loops b, Fig. 3, each having two or more such loops for the reception of the stretcher-bars and the adjustment of said bars relatively to the height of the carriers. It will be seen that the pillow A when the stretcher is folded, serves also as a cushion for the back of the person that carries the stretcher, which, when unfolded for use and in order to carry the same with ease, has the stretcher-bars Ginserted through the loops a b b c c on sections A, B, and O and strapped to section D by means of the straps and buckles d d in conjunction with the shoulder-straps B as before described and as shown in Fig. 6.

Instead of folding the stretcher .as described, the joints may be so arranged that section F will fold onto section E and the two on section D, then on section C, and finally on section B, in which case the. joint I), Fig. 5, will have to be made of sufficient width to permit this.

The stretcher-bars G may be provided with a bearing g for the reception of a wheel-axle, and such axle has then by preference two wheels is to prevent the stretcher from tipping over, so that it may be trundled like a wheelbarrow, and in this case the bearing end of the bars may be provided with a spike, so that they may performthe function of an alpen-stock, as shown in Figs. 11 and 12.

The stretcher constructed as described may be provided with legs to support itat a certain distance from the ground,and these legs are preferably so constructed as to be detachable from the stretcher-bars. In fact, for fieldstretchers if itis desired to use the legs they should be detachable, not only for facility of transportation, so that one man can carry the stretcher and the other the bars-and legs,but for other reasons hereinafter referred to, and to facilitate the carriage of the stretcher-bars I construct them of two sections hinged together.

Referring now to Fig. 9, it will be seen that the two legs g of a pair are pivoted to a crossbar g so as to fold on said bar, and tosaid cross-bar is secured at each end a strap g for the reception of the stretcher-bars G, the cross-bars g being secured against displacement by a set-screw g working in the straps g, and to avoid the wear of the stretcherbars G, due to the impingement of the setscrews, I apply metallic plates g at the point of application of the legs, upon which the set= screws 9 impinge.

Fig. 10 illustrates a portion of the two sections of a stretcher-bar hinged together at g and provided with keepers g for a locking-bolt 9 that is provided witha stop 9 to prevent its sliding out of the keepers and being 10st. The stretcher may also be carried on a two-wheeled truck or on a sled, as shown in Figs. 14, 15, and 16, 17, respectively. In the case of a two-wheeled truck the longitudinal bars R of the truck-frame are supported from springs S, secured to the axle A and at bothends of the said truck-frame are secured U-shaped bearings 'i for the reception of the stretcher-bars, which are secured against displacement in said bearings by means of a set-screw t". A foot or support L, hinged to the cross-bars of the truck-frame and braced by a brace L, is held in a vertical position by means of a set-screw L which on being unscrewed will allow the foot to be swung inwardly, the brace sliding along the same, and said parts may then be locked together by means of the set-screw L as shown at the left of Fig. 14-.

The means for securing the stretcher-bar to a sled-frame are substantially the same as those described in reference to the wheeled truck-frame, and in either case I preferably construct the frames so that they may be taken apartas for instance, by 'means of tongue-and-socket joints and locking-pins P, Fig. 16.

Whether for field or other purposes, it is not only desirable but in may cases necessary that the patient or woundedishould be .carried in a sitting posture, and this is not possible with stretchers as heretofore constructed, so far as I am aware, and one of the objects of my invention is to provide means to effect this.

too

Referring now to Fig. 13, it will be seen i that the sections E and F (shown in full lines,) are folded together and held in proper position by means of the straps cl and in dotted lines in their extended position, in which the section F forms the foot-rest, which is also held in proper position by said straps d that the section D or the sections D and E are supported on an inclined plane from the stretcher-bars G (indicated in dotted lines) by the straps d or by said straps and the straps 61 that the section 0 constitutes the seat to which the shoulder-sectionB is secured, so as to lie in an inclined plane, by means of the angle-straps 0 provided with eyes 0 and the straps b lprovided with safety or snap hooks 1, hereinbeforc referred .to. Thchead part A is securedin the plane of B which have steel-plate stiffeners inserted Minely The straps c are buckled to the buckles and the straps and buckles c are secured to the shoulder part B by means of the buttonhole flaps or flies a that button onto buttons into them, or said head-section A may be folded onto section B, and, if desired, the pillow A may then be secured to the back of A, for which, therefore, I provide eyes or loops and a strap (not shown) arranged like the loops and straps 2 and 3 on the back of section A. The individual to be transported is secured to the section 13 by means of the straps b hereinbefore referred to, if this is necessary.

Instead of solely supporting; the section D from the straps (1, said section may be supported by its joint 0, the upperjoint being in this case either sufficiently stiffened or made so tight as to prevent the free backward swing of section D. The section 0 may also be provided with an arm-rest c, which will then by preference be detachably connected with said section and provided with a segment-arm 0 adapted to pass through a sleeve 0 secured to the back of section B, so that the straps b" 0 may be dispensed with, if so desired, and the angle of inclination of section B relatively to section 0 adjusted by means of a set-screw working in sleeve 0 and impinging on arm 0 or a pin passing through said sleeve and arm.

The small straps h, of which there are four to each of the sections 13,0, and D, serve the purpose of securing a mattress or sections of a mattress,which is 01' are provided with buckles at proper points for said straps.

A stretcher adjusted to the position shown in Fig; 13 may be readily secured to a perambulator, as shown in Figs. 19 to 21. As shown in Figs. 19 and 20, the seat G of the perambulator has at its front and rear ends straps c and straps and buckles a", respectc on the stretcher-bar loops 0 of section 0,

the loops 2 on back of section 13, thereby securing the stretcher to the perambulator, which is provided withan adjustable segment-arm 072, connected with the section D, said arm passing through a sleeve on the guide or fore-wheel axle, and is secured in the adjusted position by means of a setscrew 5'. p

In order that the legs of the patient may be adjusted to different elevations, the sections D, E, and F of the stretcher are divided longitudinally, as shown in Fig. 19, in which case two adjusting-segments on will be provided, as well as the necessary straps and buckles d f f e for said sections, as will be readily understood. 1

To facilitate the lifting-of the patient and stretcher onto the peramb'ulator or the lifting of the patient onto the stretcher, one of the arm-rests 1 of the perambulator is hinged to the seat 0, so that it may be readily turned down, as shown in Fig. 21, the handle 1 being detachably secured to the perambulator.

From the description of the construction of the stretcher it will be readily seen that some of the improvements are applicable to stretchers of usual construction and that a non-foldable stretcher may be constructed of interwoven cane, and I do not wish to limit myself to the application to a foldable stretcher of those improvements that may be applied to non-foldable stretchers.
