UNITED STATES JOHN ROMSTEAD, OF SEATTLE, WASHINGTON.

- WATER-HEATER FOR GAS-STOVES.

Application filed. September 13, 1919.

To all whom it may concern.

Be it known that I, JOHN RoMs'rnAD, a citizen of the United States, residing at Seattle, in the county of King and State of Washington, have invented a certain new and useful Improvement in Water-Heaters for Gas-Stoves, of which the following is a specification.

My invention relates to improvements in water heaters for gas burning stoves and the object of my invention is to provide a water heater in the form of a water coil that may be arranged within the oven of a gas burning stove in such a manner as to be out of the way and to utilize the heat of the baking and broiling ovens to the best advantage to heat water, thereby doing away with the necessity of a separate water heater of the type commonly used where gas stoves are employed.

A further object is to provide a coil that is easy to install and that is especially adapted for use with the type of oven burners common to ordinary gas burning stoves.

The invention consists in the novel construction of a water heating coil and the adaptation and combination of such coil with an ordinary gas burning stove as will be more clearly hereinafter described and claimed.

In the accompanying drawings Figure 1 is a view in vertical cross-section, substantially on a broken line 1, 1 of Fig. 2, of an oven having my water heating apparatus installed therein, and

Fig. 2 is a view in cross-section of the same, substantially on a broken line 2, 2 of Fig. 1, the water heating coil and burner pipes being shown in plan.

Like reference numerals designate like parts throughout the drawings.

Referring to the drawings the numeral 5 designates a baking oven and 6 designates a broiling oven that is separated from the baking oven by a partition wall 7 and is provided. with four transversely arranged parallel burner pipes 8, 9, 10 and 11 that communicate with a gas inlet pipe 11.

The burner pipes 8, 9, 10 and 11 are spaced below the partition wall 7, as shown in Fig. 1, and two alternate burner pipes, as the pipes 9 and 11, are perforated on their upper sides for directing divergent jets of upwardly against the partition wall 7, while the two other burner pipes 8 and10 are perforated on their lower sides Specification of Letters Patent.

Serial No. 323,659.

for directing divergent jets of gas downwardly into the broiling oven 6.

,The perforations in each pipe are preferably arranged in two rows, as shown, and are arranged todirect the gas outwardly in divergent jets.

The water heating coil comprises four straight sections of water pipes 12, 13, 14 and 15 that extend crosswise of the oven and parallel with the burner pipes and are connected with each other by shorter sections 16, 17 and 18.

The pipes 12 and 15 are connected with other pipes 20 and 21, respectively, that are arranged to project outwardly and may be connected in the usual manner with a hot water storage tank, not shown.

The coil is preferably formed so that all of the pipes lie in the same plane and such coil is supported in the space between the partition wall 7 and the burner pipes 8, 9, 10 and 11, the water pipes 14 and 15 being spaced just far enough to be directly in the path of the divergent jets of gas that are emitted from the burner pipe 11, and the pipes 12 and 13 being similarly arranged and disposed with respect to the burner pipe 9.

The ovens may be of any standard form of construction and may be provided with doors 22 of the usual type.

When arranged in the manner shown and described, the water coil will always be subject tothe heat from the oven burners when the latter are lighted and will serve to heat water without detracting materially from the efficiency of the oven.

The water pipes being located directly in the path of the gas jets that are emitted from the burner pipes will always be in the most highly heated area of the oven and will serve as deflectors to spread the flame from the burners before it strikes the bottom wall 7 of the oven 5.

In practice the water coil may be formed,

of a single pipe bent into the shape shown or it may be made of a plurality of short sections of pipe connected with each other by elbow fittings in a Well known manner.

My water heating coil occupies space that is not available for any use in the oven and is very quickly and easily installed by cutting holes in the rear wall of the broiling oven and then inserting the made up coil through the oven door and making the necessary pipe connections.

Obviously, changes may be made in the forms, dimensions and arrangement of parts of my invention without departing from the spirit thereof.

hat I claim is:

In an apparatus of the class described, the combination with a baking oven, of a broiling oven disposed below said baking oven and separated therefrom by a partition wall that serves as a bottom wall for said baking oven and a top wall for said broiling oven, a plurality of burner pipes eXtending crosswise of said broiling oven and spaced below said partition wall, certain of said burner pipes being arranged to direct jets of gas upwardly toward said partition wall while other burner pipes direct jets of gas downwardly, and a continuous water heating coil supported between said partition wall and said burner pipes, said water coil having inlet and outlet pipes that project outwardly through the rear wall of'said broiling oven and being provided with water heating pipes that are arranged in pairs with each pair spaced slightly above the burner pipes having the upwardly directed nozzles and the pipes of each pair at opposite sides of the burner pipe in proximity thereto and substantially parallel to said burner pipes and are disposed in the path of the gas jets that are directed upwardly from said burner pipes.

In witness whereof, I hereunto subscribe my name this 6th day of September A. D.

JOHN ROM STEAD.
