WATER HEATER.

Application filed November 19,- 1923, Serial No. 675,739. RenewedAugust 3, 1925.

To all whom it may concern:

Be it known that I, ELLIs- H. l/VILKINSON, a citizen of the' United States, residing at Bristol, in the county of Washington and State of Virginia, have invented new and useful Improvements in Tater Heaters, of which the following is a specification.

The object of this invention is to heat the water in a tank or reservoir employed in connection with a cooking range or the like, by providing circulation between the reservoir and a pipe extending through the lower portion of the flue at the back of the range.

A further object is to avoid excessive heating of the water, which frequently occurs when a moderately hot fire is maintained and when the pipe providing for the circulation of the water extends into the firebox or connects with a water back or water front in the fire box.

A still further object is to effect the desired result by direct and inexpensive construction, without change in the construction of the stove or range, beyond the provision of openings in the flue indicated, for the insertion ofcthe pipe.

With the foregoing and other objects in view, the invention consists in the novel construction and arrangement ofelements described, illustrated, and claimed, it being understood that modifications may be made within the scope of the claims without departing from the spirit of the invention.

In the drawings, Figure 1 is a View of a range in rear elevation, with my improvement applied thereto; Figure 2 is a similar view of the range, with a portion of the rear smoke flue broken away to show a water pipe extending into this flue; Figure 3 is a View of the range in vertical longitudinal section, showing how the rear flue is subjected to indirect heat from the firebox; Figure 4: is a vertical section on a plane perpendicular to the plane ofFigure 3.

The flue of a range of a standard type is provided with the usual damper 11 and opening 12 for connection with a smoke pipe leading to a chimney. The lower portion of flue 10 communicates with a chamber 13 under the oven 14, and the chamber 15 above the oven communicates with the fire box 16, and indirectly in the usual manner with lower chamber 18.

Openings are provided in the side wall of flue 10, below the damper, for the pipe referred to below.

' A reservoir or tank 18 is positioned at the side of the range remote from the firebox, and pipes 19 and 20 extend respectively from the side and bottom of the reservoir into the flue 10, where they are connected by vertical pipe 21 and elbows 22, 23. Unions or couplings 2 1, 25, and drain cock .26 serve the usual purpose.

This particular connection with the rear portion of the stove, and involving the flue carrying the products of combustion, has been found especially ffective, and the water is kept at an even temperature, near the boiling point, with a moderate fire.

What I claim is:

1. In adevice of the class described, a

firebox, an oven at one side thereof, a chamber extending around the oven and having communication with the firebox, a smoke flue 1n communlcatlon with the firebox and with the upper and lower portion of the chamber, a reservoir, and pipes extending from the reservoir and connected therewith at different levels, said pipes extending into the flue, means in the flue connecting the pipes with each other, said means extending upwardly alongside a vertical wall of the oven, and a damper for diverting all products of combustion, from direct passage to the flue, into contact with the bottom, of the oven and thereafter around the pipes in the, smoke flue. f

2. The combination with a range including an oven and firebox, of a smoke flue having permanent connection with the range at points above and below the oven, a reser voir, means for circulating water from the reservoir through the flue between said P0ints of connection, and means-for direct- I ing all products of combustion to the bottom of the ovenand thereafter to said means for circulating water.

In testimony'whereof I affix my signature.

ELLIS HALE NVILKINSON.
