RANGE WATER HEATER Filed Jan. 5, 1929 2 Sheets-She et 2 f nlvc- Patented Feb. 2, 1932 UNITED STATES FRED WOODARD, LOS ANGELES, CALIFORNIA tense PATENT: FFIE RANGE WATER HEATER Application filed January 5, 1329. Serial No. 33 0,492. I

A further object is the provision ofia range water heater comprising a reservoir n the form of a tank rising from preferably;

. the after edge of the top plate of the range and having a horizontal portion'extending,

over the top plate at such a distance therefrom that it does not interfere with the normal use of utensils disposed upon the plate.

A still further, objectis th'eprovision of a range water heater of the general character described, having a warming oven disposed within the horizontal portion of the reservoir and accessible through the forward side thereof. In the inventions preferable embodiment, the parts are so proportioned and arranged that the combined range and water heater has the appearance of the conventional range having the well known type of warming oven disposed above'the top plate. A further object is the provision of a range water heater as described, having a water: back interposed between the source: of'he'at supply and the top plate, this water-back being in communication with the reservoir so that circulation of water therethrough is maintained to convey heated water from the water back to'the reservoir and cooler water from the reservoir to the water-back.

The invention possesses other objects and advantageous features, some of which, with those enumerated, will be set forth in the following description of the inventions particular embodiment which is illustrated in the drawings accompanying and forming a part of the specification. I

Referring to the drawings:

Figure 1 is a perspectiveview of a kitchen range having a water heater embodying the principles of my invention incorporated therewith.

Fig. 2 is a horizontal sectional view, the plane of section being indicated by theline 22 of Fig. 4, and the direction of view by the arrows. 7 i

Fig. 8 is a horizontal sectional view, the plane of section beingtaken upon the line 3+3 of Fig. 4, and the direction ofview by the arrows.

Fig. 4 is a vertical of section being indicated by the line/1+4 of F 3, and the direction of view the ar rows. 7 Fig. 5 is a' view similar to Fig. 4', with the adj a'ce'ntburner sheath broken away to bet-' ter disclose the positioning of th'ewate'r-back." 1 Inits broad conception, the water-back and reservoir comprising the water heater of my' invention, is adapted to be installed upon any type of stove or'range, regardless of the character of fuel employed. However, one feature of the invention is the constructionand. arrangement of parts of the water heater in V such a manner that it is adaptable for instal-. lation upon and use in conjunction with the well known type of liquid fuel range,i. e., a

range utilizing kerosene, distillate, gasoline,

or similar liquid fuel. Accordingly, the invention' is'herein described as being incor-, porated with a liquidfuelburning range of this type," it being understood. however, that I contemplate utilizingthe water heateron other types of ranges.

sectional View, the plane 7 a The rangeis shown ascomprising a top plate 6,having preferably a plurality of grids 7 therein, below eaclrof which a burner 8 is disposed, these burners, in the case of a liquid fuel'burning stove, may be either of the wick type or of the atomizing type, the latter burner-being chosen for the purpose of disclosure] All the burners 8 are supplied with fuel thr'ough a supply pipe 9 leading from a: suitable reservoir (not shown) and the burners may be selectively controlled by valves'll. 'Each of the valves 11 is i i-com: munication with the pipe 9, and leads to the atomizer of the associated burner 8. fSincethese burners form no portion "of my inven tion, they arenot described in detail herein,

.it-being understood that any suitable type of j burner may be employed.

Each burner 8 is surrounded by a suitable apron or sheath 16, the upper portion 17 of which flares upwardly to accommodate the water-back 18 which forms a portion of the water heater of my invention. This waterback is formed of any suitable conduit such as copper tubing, and is preferably in the form of a coilcor 'esponding substantially in diameter to the grid 7 below which it is positioned and in axial alignment therewith, so that the normal flow of heat from the burner 8 upwards through the grid 7, is not inter fered with.

Inlet and discharge pipes 21 and 22 re-' spectively, lead from the opposite ends of the coil 18, to a reservoir 23 which rises from preferably the after edge of the top platen, as clearly shown upon Figs. 1, e, and 5. If, instead of being positioned upon the top plate 6, the reservoir 23 is placed in back of the stove and supported by suitable braces 24, the effective area of the top plate 6 is not diminished, and the process of assembling the stove is facilitated because of the greater ease of attaching. the inlet and outlet. pipes 21 and 22 to the reservoir 23.

A horizontal portion 25 of the reservoir 23,

is spaced a sufficient distance above the top' plate 6, to permit handling of receptaclesand other utensils upon the top plate 6, without interference, but extends over at least a portion of the grids '2' so that any heat which would otherwise be wasted by passing around the utensils disnosed upon the top plate or grids, will strike this horizontal portion 24; and be at least partially absorbed by the water therein.

The forward wall 26 of the horizontal portion 24, extends inwardsto define a warming oven 27 with the result that this warming oven: 27 is completely surrounded except at its forward side, by the water reservoir. A,

suitable shelf 28, preferably in the form of a grating, may be provided within the warming oven 27; and the warming oven may also be provided with a suitable closure, if desired.

It is obvious that a single warming oven 27 or a plurality thereof, may be provided,

this choice depending largely upon the length of the stove, In the event that more than. one warming oven 27 is employed, a gauge glass 31 may conveniently be positioned between any two of the warnriinp,- ovens,.this gauge glass being incommunication at both its ends with the interior of the horizontal portion 24, and permitting observation of the amount of water contained within. the reservoir. glass 31 maybe disposed in any other convenient location. Furthermore, a faucet 32 leads from the lower side of the horizontal portion 24, with the result thatreceptacles resting upon the top plate '6, may conveniently be filled with water from the reser- However, the gauge,

voir 23. In addition to this, another faucet 33 is provided in the main portion of the reservoir 23, so that water may be withdrawn therefrom at a lower level than that of the faucet 32.

Means for filling the reservoir 23, are provided. In the event that the stove is intended for use in localities where water under pressure is not available, the reservoir 23 is provided with a funnel 36, communicating through a valve 3? and a conduit 38 with the interior of the reservoir 23. However, when the stove is intended for installation where water under pressure is available, in-

'let and outlet pipes ll and 42 are provided,

may be conveniently removed whenever desired, This splasher plate may also have one or more warming shelves 4% of any desired type, mounted thereupon. 7

Thus it may be seen that I have devised an unusually efficient type of range water heater, in that the reservoir is so positioned thatthe water contained therein is adapted to absorb most of the heat ordinarily wasted by passing around the utensils disposed upon the top plate of the range. It is believed however, that the principal source of heat for the water within. the reservoir, will be through the waterbacks 18, one. of which is associated with each of the burners 8.

It is to beunderstood that the details of the invention as herein disclosed, are subject to alteration within the spirit or scope of the appended claim. I claim:

A range comprising a top plate, a burner disposed therebelow, a water reservoir extending upwardsfrom the rear of said top plate, a portion of said reservoir extending over said top plate and being spaced thereabove, a warming oven disposed within said portion of the reservoir and. enclosed thereby except at the front, and a water-back disposed adjacent said burner in communication. with the lower end of said reservoir.

In testimony whereof I have signed my name to this specification.

FRED M. VVOODARD.
