the invention, such as will enable others. skilledin the art to which it appertains to make and use the same. 7

My invention relates. to a stretcher or the. like which isto be suspended for use, and which can be collapsed to occupy small.

. space, for-portability, or to allow the saved space to be used. The parts can be readily disassembled, and a number of them are interchangeable. The stretcher can be sus-. pended either indoors or in the open. air,

from any convenient support, as a ceiling, rafters, posts, trees, brackets, wall hooks or eyes, or so on.

This invention will be useful in barracks,

hospitals, dwelling houses, and generally. The tension produced by suspension straps is such as to help to keep my stretcher taut,

ing and bulging of the canvas or other material hereinafter termed the mattress. The stretcher has side rails and end rails and the latter are pivoted to one of the side rails. When in folded positions these end rails become longitudinal. The construction includes other details and may be according to the accompanying drawings, but is not lim-' ited thereto in minor respects. Various-accessories known to be useful in connection with beds or stretchers may be added, and are not illustrated.

Figure 1 represents a perspective view of my stretcher with part broken away. Fig. 2 shows its rails which are seen tobe, at one end, closed and strapped together. Figs. 3 and 4 are side elevations, and Fig. 5 is a plan view,-showing details which are explained later.

a, b, are the side or longitudinal rails.

0, (Z, are the end rails. The latter are connected pivotally toand under a side rail a, as by bolts 6, f. The rail Z) rests on the end rails loosely but is keptin place by suspen looped to inclose these rails; this sheet is connected to the end rails as by adjustable I straps '9 passing through eyelets g in sheet 9. Cords g or the like extend to a transverse piece g when it is desired to keep pillows, or bedding from falling overthe end of the stretcher. r

I provide means tolimitrotation of rail b; for example screw g uthrough an eyelet in sheet 9.. This rail has at each end one or more stops 5*, which thus retain about their normal positions, for a reason which will be apparent shortly.

The suspension means is shown as a combination of strapsiand cords. Thus the bases of cords Z, Z are shown above rail a, and the bases of cords 7c, above rail 6, and I provide these cords with means for length adjustment to regulate when re.- quired the" height of the stretcher above the ground or floor. j are straps on hooks j which engage eyes. of bolts 6, and these straps engage D-rings or the like, which are engaged by eyes j or the like at the bases of cords Z, Z 7'? aresleeves, adapted to be pressed down to tighten cords Z, Z on the eyes f When raised these sleeves loosen is the cords so that they can be adjusted to tion such as a flange, collar or as shown the pegs b and each strap it may bear against a peg while it also presses the side rail outward (see Fig. 4) and pulls the end rail (see Fig. 5) so as to tend to stretch the, mattress in the directions indicated by arrows. Should, therefore, there be a tendency by reason of weight on the mattress g, for rail Z) to be drawn toward rail a, that tendency will evidently meet with resistance, and in practice I find that sheet 9 is kept taut enough for comfort, and is thus unlike ordinary stretchers. The stops 3)" are located on the overlapping side rail 6 toward the ends thereof and beyond the end rails c and d, and act or serve as guiding means for .directing the upward lead of the straps h thus enabling a pulling force to be exerted on the end rails, and these stops further act as retaining or guarding means to keep the straps from being too easily detached.

1 To collapse the stretcher the straps h are movedclear of rail 1), which I push up to rail 0;. These straps are disconnected from the parts above them, and then the two end rails can be swung under the rail (1, and can be strapped as shown in part of Fig. :2. The space under rail (1 which is preserved by the distance members 0* then allows part of the sheet mattress 9, when in collapsed position to be located between rail a, and the longitudinally set end rails. It is not essential that thestraps 71. and the parts above them to which they are connected shall extend at those angles which happen'to be illustrated. The means which prevent articles falling off the stretcher may be located between the suspension members on whatever ends or sides protection is desired.

Having described this invention, what is claimed by Letters Patent of the United States is 1. A stretcher or the like, having a pair of end rails and a pair of side rails, each 'end rail being pivoted to one of the side rails, suspending means for the pivoted ends of said end rails: and their complementary side rail, andqsupporting straps or the like connected to the opposite ends of said end rails, and bearing against the copies'of this patent may be obtained for inner surface of the other side rail, so as to locate the latter, substantially as described.

2. A stretcher or the like, having a pair of end rails and a pair of side rails, each end rail being connected toward one end to one of the side rails, and the other of said side rails having its ends resting loosely upon and overlapping the free ends of said end rails, a mattress of foldable material se cured to said rails; suspending means for the pivoted ends of said end rails and their complementary side rail, guiding means on said'overlapping side rail, located toward the ends thereof and beyond said end rails, flexible members connected to said end rails toward the outer free ends thereof, and adapted to extend upwardly, in engagement with said guiding means, on the outside surfaces of said end rails and the inside surface of said overlapping side rail, and suspension means connected to the free ends of said flexible members, the whole operating to cause the overlapping side rail to be pressed and the end rails to be pulled to tauten the mattress when bearing weight, substantially as described.

8. In a stretcher a rail onone side. having pivotal connections to end rails, and on the other side a rail resting on the end rails, suspension members connected to the end rails, stops for the said members on the side rail last mentioned, a mattress attached to the siderails and connected by adjustable means to the end rails, means to limit rotation of the side rail last mentioned, and connections between suspension members to prevent articles falling off the stretcher.

.In witness whereof I have hereunto set my hand in the presence of two witnesses.
