tion by which the stretcher may be (juicklycon-` verted to a cot and cross brace construction for maintaining the two side rails in proper spaced relation with tension on the iiexible sheet or body support.

The patents also disclose some facilities `for 7 Claims. (Cl. 128--84) Vcooperative association tending, anchoring means or clips for securing strapping the patient to the stretcher and ap- I plying traction to parts of the body.

My present invention relates particularly to improvements in my general stretcher structure which materially increase the facility and effectiveness of applying and maintaining Xed skeletal traction -for broken bones.

It is an object to provide in a stretcher of the class described, closely cooperating means whereby traction may be effectively applied to i most members of the body to relieve pain and prevent further injury to fractured limbs, neck and other body portions after an accident and during transportation. i

More specifically, it is an object to provide in a stretcher or litter, two series oi closely cooperatirig, anchoring elements disposed respectively at the longitudinal sides of the stretcher and adjacent the ends thereof for anchoring traction ties and straps whereby substantially straight-line traction may be applied to the i arms, legs and spine of the patient and whereby, moreover, the body may be strapped or otherwise, xed to the stretcher in a desired, predetermined relation to permit proper traction stresses to be obtained.

A further object is the provision of a simple but highly efficient set of anchor clips for traction ties which t very compactly into the end portions of the stretcher rails or side members without interference to other parts of the stretcher and which may be quickly extended inwardly in substantially straight line relation with the legs and arms and in combination with straightline pull effect for the neck, and back. l

Another object is the provision by simplied but highly efficient expedient of a plurality of longitudinally spaced anchoring loops at eachof the longitudinal sides of the stretcher adapted for' with the inwardiy l extraction ties.

These and other objects and advantages yof my invention will be more apparent from the follow.-

ing description made in connection "with the accompanying drawings,` wherein like `reference characters refer to the same parts throughout the `several views and `in which: l

Fig. 1 is a top plan view of `an, embodiment of my improved stretcher or litter, the dotted lines indicating a human figure disposed` on the stretcher with traction applied to both legs;

Referring now to Figs. 1 to 5 inclusive, of the drawings, the general structure oi my stretcher is similar to that disclosed in my Patent No. 2,367,167 issued January 9, 1945, andcomprises a pair of two-section, longitudinal side rails, the

Ysections of which are indicated by the numeral Ill, the two sections of each rail being efficiently pivoted together centrally of the stretcher by an eiiicient pivot construction indicated as an entirety, `by the numeral Il, which as illustrated` their `corresponding ends by collapsible spreader toggles l2 as disclosed in my said patent, the outer ends of said togglesbeing secured to the `side rails and provision being made forholding said toggles in out-stretched, horizontalposi` tion, as indicated in Fig. 1. Theilexible, rec,`

In Figs. 6 yto 8, I disclose another form of my invention applied to a non-flexible litter, comprising a relatively rigid body sheet 2lwhich may be convenientlyA constructed from 1- wood or suitable composition material of elongated rectangular form,su'icientwto accommodate a human body andhaving attached to the four corners thereof and extending longitudinally thereof, rounded handle members 2|. Handle members 2l may conveniently be provided with atted anchoring portions or bases 2 la which may be rigidly affixed to, preferably, the upper surface of supporting body or sheet 20 by elongated screws or other fastening means 22.

Across the medial portion of the two handle members 2i lat each end of the litter, I attach, as by screws, 24, a traction tie-anchoring bar 23 preferably secured at its ends to the upper sides of the medial portions of the opposed handle members 2 I, to dispose the bar 23 in transverse, spaced relationship to the upper surface and respective end of the board or supporting sheet 20. This bar, as in the case of the inwardly swingable, laterally disposed, anchor clips I8 of the form of my invention first described, provides a laterally extending anchoring means to which the cords, ropes or textile, traction tying elements may be tied and secured.

For the purpose of providing anchor loops to which the ends of str-aps or other flexible securing means may be attached, I provide at each of the longitudinal portions of the supporting sheet or board 20, a series of anchoring loops 25a disposed in this form of the invention, upon the upper surface of the supporting sheet 2D and in close proxlimity to the longitudinal edges thereof. Loops 25a are formed in quite similar manner to the loops lia of my form of stretcher rst described, by weaving in and out, portions of an elongated cord or other flexible element 25, through a series of longitudinally spaced apertures extending vertically through the thickness of the board, adjacent its respective longitudinal edges. The cords 25 may be conveniently secured in place by knotting the ends thereof after tensioning the same in the threaded and woven position, as clearly shown in Figs. 7 and 8.

With this last described form of my invention, xed skeletal traction for various fractures may be applied with the body secured at appropriate portions by cross straps to the supporting sheet and with the traction ties connected with the requisite limbs or portions of the body and anchored to the anchoring cross bars 23 at appropriate points to apply straight line traction stresses.

It will of course, be understood that various changes may be made in the form, details, arrangement and proportions of the parts without 4departing from the scope of my invention.
