' WATER-HEATER.
Specification of Letters Patent Application mea February s, 1912. serial 1ro. 676,239.
To all whom it 'may concern.' Y y Be it known that I, HERBERT S.' HUM Primm, a citizen of the United States, re-
siding at the city of Kalamazoo, county of Kalamazoo, and State of Michigan, have invented certain new and useful Improvements in Tater-Heaters, of which the following is a specification.
This invention relates to improvements in water heaters.
The main objects-of this invention are,-
trst, to provide an improved valve whereby the fuel supply to the heater is completely cut olf or turned on when the temperature rises above or falls below a predetermined l point; second,'to provide an Yimproved thermostat actuated valve embodyingthese advantages which is very compact in structure and not likely to getout of repair.
Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.
I accomplish the objects of my invention by thedevices and means'describedin the.
following speciicationl l.
The invention is clearly defined and pointed out inthe claims. Y
A structure which is a preferred embodiment of my invention is clearly illustrated. in the accompanying drawing, forming a part of this specification, in which:
Figure I is a detail side elevation of a structure embodying the features of my invention, the heater being shown inconvenseveral views, and the sectional views are taken looking in the direction of thelittle arrows at the ends of the section lines.
Referring to the drawing, the heater 1 is shown in conventional' form as acoil heater' and is provided with burners 2. The heater casing 3 isindicated by dotted lines.
The heater coils'are connected by the' pipes 4 and 5 to the tank 6. The wateris deliv draw-off faucet 14 is provided 'for the tank.
'- The gas is delivered -to the burners -through the supply pipe 8. The delivery of th'e gas is controlled by my improved valve which is automatically operated by the ther- A mostat disposed within ,the tank 6 as illus-V trated. The thermostat illust-rated consists Patented July 23, 1,912. 1.
'ered to the tank through the pipe 7. vA
of an outer tubular member 9 and an inner member 10. The valve casing 11v is prov vided with a seat 12 'for the valve 13 andl with a cylinder 14 alined with the seat. The valve stem 15 is guided bythe guide 16 provided therefor'in the head 17 of the cyl inder 14 and by a suitable gland 18 through which the stem. projects to be engaged by the thermostat lever 19. This lever is pivoted at` 20 and is acted upon by the lever 21 which is pivoted at 22 and is in turn actuated by the thermostat rod 10. The valve 13 isslidably 'Y mounted upon the valve stem, that-is the valve stem and theA valve are movably assoment with both sto is so that a limited moveciated. Thev independent movement of the'. stem and valve is'limited by the shoulder-- like stop 23 and the stop pin 24. .When the valve is closed or seated, it is out of engage.-
mentA of' the stem 1s permitted'without-unseating the valve. f
Arranged within the cylinder 14 above the valve, is a plunger or reciprocating member 25. This member is preferably Aring-like or annular, as'illustrated. The
valve stem is arrangedto actuate this reciprocating or plunger member, the connection consisting of a pair of levers 26 which are pivoted on the ears 27 projeetinginwardly from the head or cap 17, the inner ends of the levers being arrangedv in the transverse slot 28 inthe stem so that the levers are rocked on their ivots 29 when the Stem is reciprocated.'
e outer ends of theleversv are connected to the reciprocating member 25 by `means of the links 30. Return, l springs 31 are provided for the lreciprocatj lng member, the springs being secured to the cap or head 17 and tothe member, and this through the connection described for the stem, returns the stem when the thermo. statlever 19 is retracted. Y Y i The valve is actuated through the springs 32. These springs are mounted upon supports which inthe structure illustrated are formed of telescopi'ngv sections 33 and 34, the

My improved valve is very simple and compact in structure and is notlikely to get out of repair. Further, the parts are all inclosed so that they 'cannotk beV accidentally displaced or disturbed by careless Workmen 'in installing the heater, or by a person cleaning the heater. When it is considered that these heaters are very frequently used in kitchens, the advantage of this will be apparent.
While I am aware-that considerable va-` riation or modification in structural details is possible Withouty departing from my invent-ion, I have .not attempted to illustrate or vdescribe such variations or modilications as the disclosure made Will enable those skilled in the art to apply my invention as V'Aprovements specifically in the form illustrated as Well as broadly within the scope of the appended claims.
