Specification of Letters Patent. i' Patented NOV. 13, 191.7.

Application led May 2, 1917. Serial No. 165,999.

To all whom it may concern.' Y

Be it known that I, JOHN ZELEZNIK, a sub'ect of the King of Austria, residing at Mulberry, in the county of Crawford and State of'Kansas, have invented certain new and useful Improvements in Stretchers, of which the follow-in is a specification.

This invention re ates to new and useful improvements in stretchers.

Theprimary object of the invention is the provision of a stretcher especially adapted for army use and having a supporting means readily foldable beneath the stretcher and capable of quick adjustment in secured arrangement when desired to be used.

A further object of the device is the provision of a folding leg or supporting member for. the stretcher, the same possessing great strength capable of rigid positioning for use while also being .easily foldable be' neath the side rails of the stretcher, consuming but little space and allowing the stretcher l to be datly positioned upon the ground.

A still further object is the provision of a stretcher having a flexible carrying portion, foldable leg members being arranged adjacent the opposite ends of the device and forming spacing means for the 'opposite sides thereof.

In the drawing formin part of this application and' in which l e reference characters refer to corresponding parts throughout the several views:

Figure 1 is a Iside elevation of the device set up for use.

Fig. 2 is a top plan view thereof, partially broken away'. j

Fig. 3 is an enlarged detail view partially in section upon line Ill-HI of Fig. 2.

Fig. 4 is a vertical sectional view, taken upon line V-IV of Fig. 3, and l,

Fi 5 is a similar view takenv upon'` line` V- of Fig. 3.

Referring more in detail to the drawing, the device broadly consists of a stretcher having opposite parallel side rails 10 between which a flexible body 11 is suspended formed of such material as canvas or leather, the opposite ends of the rails 10 being formed in the shape of handles 12 by means of which the stretcher may be readily carried.

Recess'es 13 are arranged upon the under sides of the rails 10 at opposite points spaced from the free ends thereof, a bearing late lbeiug sgpured to the bottom of eac recess. Foursupporting legs 15 are arranged for the stretcher preferably formed of strips of metal, although wood may be employed if desired, a head plate 16 being secured to 60 the top of each leg having a laterally projecting portion arranged at an oblique angle thereto, the saidhead plate adapted for flat engagement with the bottom plates 14 when the upper ends of the legs 15 are operatively 65 positioned within the recess 13 and at whic times the projecting portions of the plate 16 are arranged inwardly and in contact with securing plates 17 which overlie the inner portions of said recesses. It will be notedrthat the free end 27 of each plate 16 is preferably rounded while the adjacent faces of edges 28 of the plate 17 and 29 of the recess 13 are beveled and in parallelism with each other and with the edges of the legs 15 when positioned therein with the plates 16 flatly seating beneath the plates 14C, the arrangement forming a solid joint for the su porting legs when assembled.

A space ar y18 connects together the pairs 80 oflegs 15 and constitutes the spacing member for the rails 10. Rectangular plates 19 are carried by the outer sides of the rails 10 overlying the recesses 13, being in engagement with the adjacent portions of the legs notches 25 for riding upon the space bars 18. 95

In operation, the stretcher is normally supported upon the legs 15 arranged as illustrated in Figsl 1 and 3 of the drawing. A lug 26 laterally projects from each of the brackets 24 forlimiting the inward and 100 downward swinging movement of the adjacent strut 23 which strengthens the supporting structure when operatively positioned,` it eing noted that the nuts 22 at such times are tightened upon the bolts 20. When de- 105 sired to fold the device for purposes of transportation or to allow the stretcher to be iiatly positioned upon any member, the nuts. 22 are released allowing the upper ends of the legs 15 to be slidably removed from the 110 l,

recesses 13 and whereupon the legsare readily folded beneath the rails 10 with the struts 23 folded inwardly thereof in a manner best illustrated by dotted lines in F ig. 3 of the drawing. A serviceable stretcher is provided which is light in weight but possesses great strength.

What I claim as new is l. A stretcher comprising side rails, having terminal handle portions and provided with recesses inwardly spaced therefrom, plates carried by the rails overlying a portion of the recesses, legs adapted for positioning within the recesses, head plates upon said legs projecting beneath said cover plates and adjusting plates for the said legs.

2. A- stretcher comprising side rails, having recesses therein, plates carried by the rails overlying portions of the said recesses, side plates on the rails, a leg adjustably secured to each side plate and a head plate upon each leg adapted for seating arrangement within said recesses underlying the said cover plates when the device is operatively arranged.

3. A stretcher comprising side rails, having recesses therein, plates carried by the rails overlying portions of the said recesses, side plates on the rails, a leg adjustably secured to each side plate, a space bar rigidly secured between the oppositely arranged legs, depending bracket-s carried by the rails having lateral stop lugs and struts pivoted to said brackets with notched lower ends constantly positioned overlying the said bars and engaging 'the said lugs when the legs are unfolded.

4. A device of the class described comprising side rails, a flexible body arranged therebetween, supporting legs having socketed engagement adjacent the opposite ends of said rails, ladjustable securing means between said rails and legs, spacing means for the rails connected between the opposite legs, depending brackets carried by said rails, stop lugs upon said brackets and supporting struts pivoted to the brackets adjacent said lugs and having notched lower ends in constant engagement over the said spacing means.

n testimony whereof I aflix my signature.

JOHAN ZELEZNIK.
