Specification of Letters Patent. .i Patented Sept. 5, 1911.

Application led October 12, 1910. Serial No. 586,736.

To all whom it may concern:

Be it known that we, THOMAS E. FoGAL- SANG and BERTHA MCCUTCHEON, both citizens of the United States, residing in the city and county of San Francisco and State of California, have invented new and u seful Improvements in Hot-Water-Bag Heaters, of which the following is a specification.

Our invention relates to hot water bags and pertains/ especially to a hot water bag to be heated by electricity,

The object of the invention is to provide a simple, practical electrically heated hot `Water bag in which a naked electrode can be used; the electrode carried by the stopper which can be screwed into the hot water bagr like any ordinary stopper, or otherwise construction and combination of parts as hereinafter more and` fully described claimed having reference tothe accompanying` drawings, in whichigure 1 is a plan view in par-tial seci tion of the bag and stopper, showing the application of the invention. Fig. 2 is a section on X-'X, Fig. 1. Fig. 3 illustrates a modification of the invention on a reduced scale. Y

A, represents' a hot water bag of any suitable description.

2 is a stopper of hard rubber or other suitable dielectric material, screwed, 0r otherwise appropriately secured in the mouth of the bottle to `vform a closure therefor, and at the same time to form a support for the heating element. As shown in Fig. 1, this heating element consists of two non-corrosive high resistance electrodes 3, which are suitably fastened to two wires L@embedded 'in and extending through the stopper 2.

an equivalent* gasket 5 may beinterposed and form male members which are adapted to telescope with the female or sleeve conducting-couplers 7, which are carried by and in electrical union with the terminals of the cords 8. These metalliclsleeves 7 tit in a bushing 9 of suitable insulating material, such as hard rubber, fiber or porcelain. The lower ends of the electrodes which project within the bag A are suitably spaced and insulated from one another by a bulb or spacing member 10, of hard rubber or the like. In Fig. 3, we have shownthe electrical heating unit as wound around an insulating post. 10.

In practice, a suitable quantity of water is placed in the bag and the stopper 2 screwed in, in the usual fashion, allowing. the electrode or electrodesto be immersed in the water within the bag.l In order to keep the electrode out of contact with the sides of the bag, as the heat of the electrode might under some circumstances, injure the rubber, the insulationlO or 10 may be of sufficient diameter or size to support the inner end of the electrodes away from the sides of the bag.

To heat the water it is only necessary to connect the projecting ends of the wires 4 with a suitable source `of electric current throu h the medium of a coupler 9 and electrlcal connection 7-8. As soon as the water Vis heated to a sufficient temperature the electrical connection can be easily broken by removing the coupler 9. If the water has cooled off in the bag it is quickly reheated by restablishing the electric circuit, without having to change the water or even disturb the patient. Having thus described our invention, what we claim and desire to secure by Letters Patent is- Y 1. The combination of a hot Water bag land a stopper therefor, said stopper of insulating material and carrying an exposed electrode, said electrode adapted to -project within the bag and to be removable there-' from with the stopper, and having means on the outside of the stopper for connection with an electrical circuit, said means comprising a conducting sleeve telescoping with an extending portion of the electrode, and a bushingofinsulating material receiving and inclosing the sleeve and 'piercedv to admit a conducting wireto the electrode.

2. The combination of a collapsible hot Water bag, a stopper therefor of dielectric material in which are embedded a pair of conducting \wires, electrodesi connected with the said Wires Yand projecting. within the bag but removable therefrom with theY stopper, and an enlargement fixed by the electrode within the bag and carried by the electrodes and coperating with the stopper THOS.
