Specification of Letters Patent.

Patented Feb. 23, 1915.

Application filed September 11, 1914. Serial No. 861,200.

To all whom it may concern Be it known that 1, WILLIAM JAsKInWIoz, a citizen of the United States, residing at Lafayette, in the county of Boulder and State of Colorado, have invented certain new and useful Improvements in Stretcher- Ambulances, of which the following is a specification.

This invention relates to certain new and useful improvements in stretcher ambulances.

The primary object of the invention is to provide a structure that is readily moved about upon ground wheels and which is capable of positioning the occupant in a reclining or partially sitting posture.

A further object is to provide a stretcher with a spring-mounted mattress, the device being adjustable to allow the mattress to assume different positions and being also provided with an adjustable head rest.

With these general objects in view and others that will appear as the nature of the invention is better understood, the same consists in the novel combination and arrangement of parts to be hereinafter more fully described, illustrated in the accompanying drawings and set forth in the appended claims.

In the drawings forming a part of this application and in which like designating characters refer to corresponding parts throughout the several views, Figure 1 is a side elevation of the device in its extended reclining position. Fig. 2 is a central vertical longitudinal sectional view thereof positioned in its chair formation. Fig. 3 is afront elevational view of the upper portion of the device partially broken away, and Fig. 4 is a perspective view of the rodconnector for the resilient supports of the mattress.

Referring more in detail to the drawings, the device broadly consists in a main supporting frame 10 comprising parallel side bars having a transverse rod 11 at one end thereof which is employed as a handle and having the axles 12 of the ground wheels 13 journaled in the forked forward ends of the bars whereby the device may be moved or.

trundled after the manner of a wheel-barrow. A rod 14 is also positioned transversely of the frame 10 and in spaced relation and parallel to the handle 11 and has two downwardly extending legs 15 journaled upon the said rod and adapted to rest upon the ground for supporting the rear end of the structure when positioned as illustrated in Fig. 1.

A back rest 16 is pivotally mounted upon the transversely positioned rod 17 of the frame 10 and has extensions 18 projecting below the said frame and constituting seat members for further supporting the device. A transverse cleat 19 is provided at the upper end of the back member 16, and the lower edge of a head rest canvas is secured to the rear edge of the said cleat by means of the cords 21. Arms 22 are slidably mounted upon the outer side of the back member 16 by means of bolts 22 carried by the said back member and projecting through longitudinal slots 24 of the said arms 22,the arms being retained in their adjusted positions by means of the set nuts 25 upon the said bolts. A cross-bar 26 is provided between the outer free ends of the said arms, and has the upper edge of the head rest canvas secured within the longitudinal slot 27 thereof. It will thus be seen that regardless of the position of the stretcher, the canvas 20 may be adjusted as desired by means of the adjustable arms heretofore described.

A mattress 28 of any desired form such as a fabric or canvas is secured to the frame and back member being flexibly suspended therebetween. A transverse rod 29 carried by the frame 10 has the lower and rear end of the mattress secured thereto, while the upper forward end of the mattress is provided with a similar rod 30, which rod is connected beneath the cleat 19 by a plurality of springs 31. A resilient spring base is provided for the mattress and consists of oppositely positioned springs 32 having a central connecting bar 33. The lower ends of the lower pair of springs 32 are connected to the rod 14 by connection wires 34 while the upper ends of the upper pair of said springs 32 are attached to the lower side of the cleat 19. The spring structure is thereby suspended beneath and in contact with themattress 28 thus forming a resilient bed bottom support for the occupant.

Side arm members 35 are pivoted together as at 36 and are also pivoted to the rod 17 as well as to the back member 16 as at 37 upon the inner sides thereof, and adjacent the top cleat 19. Adjusting arms 37 are provided at each side of the device being pivotally connected to the arm at the pivotal points 36. The opposite ends of the adjusting arm are adapted to be secured to the, frame 10 by means of removable pins 38 projecting through the arms 37 and positionable in any one of the perforations 39 of the said frame which may be desirable, it being noted that these perforations are provided upon the opposite sides of the frame and in alinement with each. other. It will thus be seen that with the opposite pins 38 positioned in the forwardmost pair of perforations 39, the arms and 37 will be forced forwardly into their positions as shown inFig. l and with the back member tilted forwardly to its fullest extent, thus positioning the spring structure and its mattress 28 in a stretched position and forming a substantially smooth unbroken bed. By shifting the pins to any other pair of the said perforations 39, the tension of the mattress and its spring may be lessened, the most lax position of the members being provided when the pins are positioned in the rearwardly arranged perforations as illustrated in Fig. 2. It will be seen that this shifting of the adjusting arms 37 and their retention by the pins 38 also shifts the side arms 35 and the back member 16 accordingly, while in some of the positions, such as the reclining position shown in Fig. 1 the feet 18 will be out of contact with the ground but in other positions such as the chair formation as shown in Fig. 2, the feet 18 'are supportingly positioned upon the ground.

An adjustable strap member 40 may be provided if desired upon the frame 10 and adjacent the lower end of the mattress, and whereby the occupant may be strapped to the stretcher.

The complete operation of the device will at once be apparent from the present detailed description thereof, and while the forms of the invention herein set forth are the preferred embodiments thereof, it is to be understood that minor changes may be made therein if desired without departing from the spirit and scope of the invention as claimed.

What I claim as new is 1. A stretcher comprising a frame, a back member pivoted thereto, a top cleat pivoted upon said back member, a plurality of connecting springs secured between the said their inner adjacent ends, a mattress fabric having its lower end secured to said frame, and spring connectors between the upper end of said fabric and said back, the said fabric being positioned in flat contact upon the said pairs of springs.

3. In combination with the back support of a stretcher, arms slidably positioned on the opposite outer faces of said support and having longitudinal slots therein, bolts carried by said support and projecting through said slots, set nuts upon the said bolt, a cross arm between the ends of the said slidable arms, a fabric having its lower end secured to the upper end of said back sup port, the said cross-arm having a longitudinal slot therein, and the upper end of said fabric being secured within the said slot of the said cross-arm.

a. A device of the class described comprising a frame, wheels supporting the frame at its forward end, a handle at the rear end of said frame, an inclined back pivoted to the said frame and having relative movement therewith, side arms pivoted together and pivotally connected between the said back and frame, adjusting arms between said frame and side arms, a spring structure between said frame and back, a mattress fabric secured to said frame and resiliently attached to said back, and an adjustable head rest carried by said back, and constituting a substantial continuation of the said fabric.

In testimony whereof I aflix my signature in presence of two witnesses.
