HOT-WATER BAG.

Specification of Letters Patent.

Patented Sept.v 23, 1919.

Application Bled Hay 7, 1918. i Serial No. 233,023.

To all whom z't may concern:

Be it' known that I, `MAURICE L. REID, a citizen of the United States, residing at gan Francisco, in the county of San Franclsco and State of California, have invented certain new and useful Improvements in IIot- Water Bags, of which the following 1s a specification.

The present invention relates broadly to improvements in receptacles and to that specifietype known to the-trade as hot water bags, bottles, syringes or the like. Receptacles ofthis character are generally made of rubber and are very prone to spring leaks sooner or later so that their utility is quite limited. This is mainly due to the manner in which they are made, that is, their` inherent structural defects', in that they are not properly reinforced .to withstand the rou h usage to which the are put, or to wea messes produced by t e effect of the heat from the contents, or to the disintegrating effect of the chemicals that may beQembodied in the liquid .introduced therelnto, causing the receptacle to develop thin spots that give way in due course.

It is to overcome these disadvantages that my invention has as its objective and to this end I resort tothe expedient of reinforcin the receptacle as a whole both in regar to its seams and other points where the strains are greatest, resulting in considerable prolongation of the life of the article under the most trying requirements, for exam le, of hospital use.

hese and such other objects as may hereinafter appear are attained by the novel construction, combination and arrangement of parts to be hereinafter specifically described and claimed. Reference will now be had to the accompanying drawings forming a part of this specification, wherein: i

Figure 1 is a fragmentary view of the upper portion of a bag constructed in accordance with this invention, parts being broken away and shown in sectionto clearly disclose the details of construction;

Figs. 2 and 3 are sectional views somewhat enlarged and taken about on the lines 2 2 and 3-3 of Fig. 1, respectively;

Fig. 4 is a fragmentary view of the lower end of the bag showing the reinforced supporting tab more clearly; and

Fig. 5 is an enlarged sectional view through the neck portion of the bag.

Throughout the following detail description and on the several figures of the drawings, similar parts are referred to by like reference characters.

The material of the body portion of the bag which forms the subject matter ot' this invention is preferably of pure rubber interlaid with special strong cotton cloth or the like so that the article as a whole is built somewhat on the same principle as an automobile tire. In other words, it will be observed in Figs. 2 and 3 that the walls of the bag consist of an outer layer of rubber 1, an inner layer 2, and an interposed layer of fabric 3. The edges of the respective walls are vulcanized together in the customary manner but these seams in mi construction are doubly reinforced. In ot er Words, interiorly of the body I provide a rubber reinforcin` strip 4 extending entirel, about the vulcanlzed scam from one side o the neck to the other side. Exteriorly I employ a further reinforcement for lthis seam construction in the form of a rubcially formed to reinforce this part of the bag which is most often subjected to considerable strain. At the neck the mouth of the bag is provided with the usual metallic thimble 7 corrugated to constitute threads to receive the stopper 8. This thimble is set and vulcanized in pure rubber and extending about the outer layer of rubber is a wire band 9 which presses the rubber into the grooves of the thimble and prevents any ikelihood of displacement of the latter. Finali', about this neck portion I apply a renilorcing strip of combined rubber and fabric, as indicated at 10, similar in fact to the reinforcing strip comprising the

elements

5 and 6 above described.

The bag is providedwith the usual funnel like entrance 11, and the fingerloop 12 to which the loss preventing connection 13 is attached at one end and to the stopper 8 at the other end.

In addition to the foregoing, the upper portion is provided with a further .reinforcing layer of rubber as indicated at 14 adhered to the walls of the bag and passing beneath the outer reinforcing strip 5-6 for the ed es of the bag.

At t e bottom the bag is provided withI the usual hanging` or supporting` tab 15.wit'h the eyelet 16, this tab being formed of fabric reinforced rubber as clearly indicated in Fig. 4. It will fbe apparent from the foregoing that the bag made in accordance with this description y and arrangement is as strong as it is possible to construct it to best meet the requirements of usage in hospitals and other places.

Having thus described my invention, what I claim as new is:

Lemma tentsof the bag and the fabric'and an outer 30 and similarly formed reinforcing strip.

In testimony whereof I aiix my signature.
