SUPPORT FOR MATTRESSES.

Application filed September 29, 1923. Serial No. 665,636.

To all whom it may concern.-

Be it known that I, Onnrsv G. OTEWALT, a citizen of the United States, residing at Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in Supports for Mattresses, of which the following is .a specification. n

This invention relates to improvements in mattresses particularly designed for automobile bodies.

The object of the invention is to provide a mattress which may be readily and quickly installed in the body of an automobile, so arranged that it can be rolled into compact form for storage. A further object of the invention is to provide improved, means for supporting a mattress in the body including novel means for applying a tension to the strips composing the mattress.

In the accompanying drawings:

Fig. 1 is a plan view of a mattress embodying the improvements shown supported from the body of an automobile, only so much of the body being shown as is necessary to illustrate the manner of installing the mattress. 1

Fig. 2 is a plan view of a portion of the tension applying devices.

Fig. 3'is an end view of the same.

Fig. 4 is a section on the line 4 -4 of Fig. 2.

Fig. 5 is a section on the line 5-5 of Fig. 2.

Referring to the drawings 1 represents a series of longitudinal strips of fabric webbing, or other suitable material, connected and spaced apart by a series of transverse strips 2 of the same material. ends of the longitudinal strips are connected to a cross rod 3 preferably by forming the strips of two plies sewed together excepting the extreme rear ends, which are left unsewed to form loops which embrace the rod 3.

The front ends of the longitudinal strips 1 are attached to another cross-rod 4 preferably by connecting all of the stripsto a pocket 5 of fabric through which the rod extends. The rod 3 is supported from any suitable point of the body such as the posts 6 at the rear end of the body and to this end each of the posts is provided with a hook 7 to receive an eye 8 of a triangularshaped connecting member 9, the forward The rear 7 end of which is provided with a pair of 'eyes 10 to receive the ends of coil springs 11,

the other ends of the springs being formed with eyes which encirclethe rod 3.

Two of the cross-strips of webbing, such as the ones indicated at 2, are connected with the sides of the vehicle body, such as the posts indicated at 12, and to this end each of these posts isformed with a hook 7 similar to the ones attached to the posts6, and to each of whichishooked one end of a coil spring 13, the other end of which is hooked to a ring 14 which in turn is embraced by the looped end of the webbing 2. There is indicated at 15 a winding shaft for placing tension upon the longitudinal 7 strips composing the mattress. This shaft is provided with a series of hooks 16 (Fig. '5) the shanks 17 of which are in the nature of pins driven into openings in the shaft, and to each of these hooks is connected an extension .1 projecting through certain of the longitudinal strips, preferably the two side strips and three equally spaced intermediate strips, these extensions being formed with eyes 18 to receive the hooks. One end of the shaft is provided with a grooved portion 19 to receive an eye formed on one end of a coil spring 20, the other end of the spring being connected with a hook 7 secured to a forward post 21, such as the windshield support. The other end of the shaft is reduced as indicated at 15 and also is provided with a groove 22 to re ceive the eye 23 formed on one end of a coil spring 24 theother end of the spring being formed with an eye 25 to receive the hook 7 formed on the opposite post or windshield standard 21.

Formed on or rigidly connected with the roll 15 is a ratchet wheel 26. Loosely mounted upon the roll 15 adjacent the outer side of the ratchet wheel is a pawl-carrying arm 27 held in position by a cotter pin 27 and having pivotally connected therewith, as at 28, a pawl 29, the nose of which'is held in engagement with the ratchet wheel by a coil spring 30 one end of which is inserted over a finger 31 on the tail 29 of the pawl, the other of which is inserted over a finger 32 projecting from the arm 27. The rear end of the arm 27 is provided with a loop or sleeve 33 which encircles the spring 24 and is for the purpose of preventing the arm 27 from rotating.

The operation is as follows: In installing the device the members 9 are applied to the rear hooks 7 a-ndthe springs 13 to the side hooks 7. It will be observed that thes-prings 18 project at a slight angle with their enter ends forward of the inner ends so thatthese springs would serve to support the :greater portion of the mattress in the event of breal age of the forward supporting devices. The springs 20 and 24 are then secured .to the forward hool'z's "7.

Tensioni's'fthen applied to the longitudimishaps of the mattress byiotati'ng the shaft byany-suitable means such as by inserting the squared pend-of a "crank in the 15 Sqe'are'aepenin .15 in the extension 15.

T'he pawlcooperates with the ratchet wheel i f h d the i t "against retrograde move- Astensionfis applied to the springs the shaft must "approach the rear rod 3 andduring this movement of the shaft 15 the sleeve sli'c'les zupon the springQ't, but maintains its engagement therewith so as to the pawl carrying arm from turning. Torem'ove the mattress the pawl 25 2 9'i's disengaged from the "ratchet wheel by pressing upon :t'he t a'il thereof and the shaft thus allowed to rotate back to its original positioniintil the tension upon :the verious springs is relieved, after which the springs may berea'dily "detached from the various 'heoks ,7 and the mattress rolled up for storage.

In testimony whereof, I have hereunto set my hand this 21st day of September, 1923.
