STRETCHER 3 Sheets-Sheet 3 Filed Aug. 17 1931 provided at one side with an Outstanding flange 21 havingv a notch or open-ended slot 22 therein.

At its opposite side, thesaddle is provided with a pintle 23 about which is fitted one end of a strap 24 which carries a clamping bolt 25 and wing 'nut 26 at its .free end, the bolt being,

T-shaped, as shown in Fig.4, and the free end-of the strap being secured around the headof the T. When the stretcher frame has been placed uponthe several seats 20, the respective straps 24 {are swung over the frame, as shown in Fig, 2, and the bolt'25 is engaged through the notch 22 after which the nut 26 is turned home against the une be effectually' clamped within the seat as will be understood. On the under side of veach seat is a short depending tube 27 having an annularlyextending slot 28 inone side to receivethe upper end of 1 the spring-14,. as shown in Fig; 3. A

sleeve 29 has its upper end threaded into thetube 27,fanda thimble 30 is slidably mounted upon the lower end of said sleeve, anrexpansion spring 31 being hous'edwithin the sleeve and bearing at its s oppositeiends against the spring .14 and the end i sleeve 29, whentu'rnied home in the tube 27, will cl amp the end'ofjthe spring 14 against the bottom'o'f theseat'20, "and the thimble mayj'beheld' against dropping-from the sleevefin any preferred;

I also provide a foot rest which is" preferably a board or plate 59 mounted upon arms 60 pro jecting from eyes or loops 61' secured upon the end member of the stretcher frame. Collars 62, are fixed within the board 59, slidably encircling the arms 60 and having stems projecting through the rear side of the board andfitted with nuts63 whereby the foot rest may bejadjusted vertically in an obvious manner to relieve an injured foot or leg of the weight of the covers; w 1
