CHICAGO, ILLINOIS, A CORPORATION or ILLINOIS 1 HOT WATER BOTTLE Application filed December 28, 1928'. Serial No. 329,066..
This invention relates mainly to hot water bottles of the ordinary hospital or domestic type, and especially to means for safeguarding users against burns therefrom. Heretosay appreciably above 140 degrees F. But so far as I am aware no adequate means have ever been devised to guard against such burns, and to the best of my knowledge and belief no means of this sort whatsoever are to be found on hot water bottles now on the market. 1 p
The main objects of this invention are to provide thermostatic means applicable to hot water bottles and the likefor promptly indi cating positively and through mechanical operation any excessive temperature; to provide such means'of interchangeable character for ready removal and renewal, andjadapted for application to ordinary hot water bottles, such as are commonly found on the market; to provide such means adapted to cause prompt leakage of water incident to excess temperature; and to equip a stopper for these purposes adapted to take the place of the ordinary stopper.
An illustrative embodiment of this invention is shown by the accompanying drawings in which:
of a hot water bottle of usual design equipped with a plug embodying this invention.
Fig. 2 is an enlarged axial section through the plug and showing details of the thermostat and valve whereby the purpose of this invention is accomplished.
Fig. 3 is a bottom plan of the plug of Fig. 2.
Fig. 4 is a greatly enlarged sectional detail of the gas filled thermostatic element.
In the construction shown in the drawings, the water bottle 1 is of ordinary design and is provided with a stopper 2 fitting in the upper part'of the passageway 3 in the neck 4. The plug 2 is provided with a rubber bearing ring or gasket 5 to seat on the upwardly facing shoulder 6 in the lower part of aperture 3 for sealing the bottle when the plug is in place.
Y The plug 2 comprises mainly a main body such burns have occurred from time to time, incident to the water beingitoo hot, that is to part 7 ofhard material threaded exteriorlyto fit in the threaded part of aperture 3. This plug is providedwith an upstanding handle or bail 8, the ends of which are set rigidly in a horizontally outstanding flange formed oirtlie upper part of member 7.
The gasket 5.is secured to the lower edge of member 7 by means of a channel ring 10 preferably soldered to the lower edge of mem-' ber 7 and having its lower flange 11 disposed against the underside of the inner edge part of the gasket}; The-member 7 has an axial I passageway 12, the upper part of which is of relatively small diameter, the lower and main part being threaded as at 18utoengagethe thermostat housing shell 14 which is of. substantially inverted cup-shape. V. An annular. gasket 15 is disposed between the downwardly facing shoulder. 16 of member 7. and the upwardly facing shoulder 17 of shell 14,- so as to seal the passageway 12 at this point when the shell is in place.
Said shell 14 has an upwardly extending relatively'narrow tubular part 18 on the upper edge of which, to close port 18, is seated the valve 19. Said valve is fixed on the upper end of a stem 20, as by nuts or equivalent means. Said stem 20 is fixed at its lower end on the'top side of athermostat 21,. the lower side of which is carried by a' Fig. 1 is a sectional view of the mouth part stem. 22, mounted rigidly on a cross bar 23 secured to shell 13 as by soldering. 1 I
Said therm0stat21 is of the fluid-pressure type and'comprises one or more bellowssections filled with thermo-responsive gas, as
for instance,ether orot-her suitable material.
- Adjustment of the device is obtainable at the lower end. of stem22, saidstem being threadedin the bar 23. For convenience in turning the stem 22, the lower end is slotted at 24 for operation by a screwdriver, and adjustment is fixedbymeans of the nut 25. If
a considerable amount of pressure has to? develop in the chamber of thermostat 21 be fore the valve 19 will be lifted. This provision insures a ti ht closure under normal heat conditions. K screen 26 is soldered to the top of body 7 to protect the thermostat and valve.
As will be apparent, I have thus provided a fluid receptacle 1 having a passageway 3 or more specifically a port 18, equipped with a valve 19 controlled by a thermostat 21 which being exposed to the fluid contents is responsive to the temperature thereof.
In using hot water bottles equipped with indicators, such as herein described the bottle is filled with hot water of approximately the desired temperature. If by any chance it is too hot, that is to say of a higher temperature than that for which the thermostat is set, the valve will open automatically and cause leakage of water which will be instantly apparent. Such leakage will be an indication to the attendant that the water is too hot and should be adjusted either by refilling with cooler water or by adding an appropriate amount of cold water. The thermostat is preferably adjusted for the maximum permissible temperature at the time of manufacture, namely, about 140 degrees F. but if, for any reason, a differenttemperature is desired, as for instance degrees F., the adjusting screw may be changed accordingly at any time.
Although but one specific embodiment of this invention is herein'shown and described, it is to be understood that numerous details of the construction shown may be altered or omitted without departing from the spirit of the invention as defined by the following claims.
I claim:
1. In a hot water bottle stopper having a port, in combination with a valve therefor a thermostat exposed to the fluid contents and arranged to control said valve, and means on said stopper for adjusting said thermostat.
2. A hot water bottle stopper having thermostatic valve means therein arranged to cause leakage of water in response to excess temperature.
3. A closure for hot water bottles comprising a plug having a bottle outlet passageway therethrough, a valve to normally close said passageway, a thermostat to open said valve in response to excess heat, and means for controlling said thermostat.
4. In a hot water bottle having an outlet and a closure plug therefor, said plug being chambered and having a restricted outlet port for said receptacle in combination with a valve therefor, and a thermostat mounted in the plug chamber and exposed to the contents of the receptacle, and said valvebeing responsive to said thermostat.
Signed at Chicago this 26th day of December, 1928.
