HOT-WATER BAG.

Specification of Letters Patent.

Patented Feb. 15, 1916.

Application filed June 9, 1911. Serial No. 632,216.

To all whom it may concern:

Be it known that I, CHARLES I. Coon, a citizen of the United States, residing at Marshalltown, in the county of Marshall and State of Iowa, hat e invented new and useful Improvements in Hot-Water Bags, of which the following is a specification.

This invention relates to hot water bags, and has for an object to provide means whereby the sides of the bag can be effectively maintained in parallel relation with respect to each other so as to possess an unbroken surface which may be fully exposed to the body of the patient when the bag is in use.

Another object of the invention is to provide sustaining devices for connecting the parallel walls of the bag which will include foldable members constructed so as to permit the bag to be readily collapsed whcn desired, such connections to be either by internal or external means.

In the drawing, forming a portion of this specification and in which like numerals of reference indicate similar parts in the several views: Figure l is a side elevation of the bag. Fig. 2 is a horizontal section on line 22 of Fig. 1.

The water bag 1 as shown herein, is of the usual well known construction, being preferably formed of rubber and provided at one end with the filling mouth 2 and a suspendingtab 3, and at the opposite end with a suspending tab 4. For the purpose of providing for a uniform distribution of the water and to cause the parallel sides of the bag to be sustained in parallel relation with respect to each other so that the opposite sides of the bag each present a plane or unbroken surfacethroughout, I provide the sustaining devices 6. These devices are preferably arranged in parallel rows transversely of the bag, being preferably located interiorly of the bag, and as shown, each comprises supporting plates or disks 7 which are vulcanized or otherwise suitably secured to the parallel sides 5 of the bag and connected with each other by the companion elongated links 8, said links being of a length equal to one-half of the transverse extent of the bag. The inner ends of the links are connected together and the outer ends are preferably mounted in the central eyes 9 in the supporting plates '7. This construction is such that when the links are distended relatively the sides 5 will be held in parallel relation throughout and positively held against swelling away from each other under the weight of the water. From this construction it is obvious that the sides 5 present relatively broad uniform plane surfaces which may be arranged in effective contact with the body of the patient while being treated. The links 8 are foldable on each other so that the parallel sides 5 of the bag can be collapsed to permit of the bag being folded into a very compact package.

I claim:

In a hot-water bag the combination of rows of transversely extending stay members, said stay members conslsting of palrs of elongated metallic slotted links connected together, of disks secured upon the opposing walls of said bag, and of eyes formed upon said disks, each pair of links being looped to said eyes so as to have their ends designed to engage said-disks.

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

CHARLES P. COOK.
