HOT-WATER HOUSE-HEATER.

Specification of Letters Patent.

Patented Nov. 30, 1909.

Application filed October 14, 1907. Serial No. 397,438.

To all whom it may concern:

Be it known that I, MARGARET A. Wrnoox, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Hot-Water House-Heater, of which the following is a specification.

An object of this invention is'to provide for householders, novel, cheap, convenient, economical, safe and satisfactory means for heating the apartments of a house; the fuel by which the heat is effected being preferably oil or gas.

Another object is to provide a compact watercirculating house-heating system adapted for use in country places and elsewhere unprovided with water-pressure systems; said system being adapted to be made wholly of pipe, pipe-fittings, and castings, at a factory and set up with a minimum amount of labor by an ordinary plumber.

The invention may be employed in connection with-cooking apparatus and will be so illustrated in the accompanying drawings.

The accompanying drawings illustratethe invention.

Figure 1 is a skeleton perspective view of this newly-invented apparatus installed in a house, a fragment of which is shown in solid lines, and other parts in dotted lines. A portion of the flue is broken to expose parts that would otherwise be hidden. Fig. 2 is a perspective view of a portion of the apparatus on a larger scale, viewed from the inside of the house. Fig. 3 is a fragmental cross-section of the refractory partition, looking to the left from the vertical midline of the damper shown in Fig. 2. Fig. 4 is a fragmental perspective detail from the outside of the house. Fig. 5 is a fragmental sectional detail illustrating the pressure relief-device. p

1 designates a flue which may be built of any suitable material, as reinforced concrete, brick, or the like, and which may be located at any suitable place as in the outside wall 2 of a building.

3 is a stove structure constructed of any suitable refractory material or materials, at the base of the flue, and 4 is an oil or gas burner in a combustion chamber or fire-box 4 in said stove structure to normally supply heat for heating the apartments. 5 of the house, and for heating an oven and otherparts of a cooker 6 located in one of said apartments and forming a part of the stove structure. Such apartment 5 may serve as a kitchen.

7 is a passage between the fire-box 4 and the cooker6 to admit heat and flame if desired, from the fire-box into the cooker.

8 is a Valve or damper for the passage 7 the same being mounted on a pivot 9 controlled by a handle 10 and adapted to stand at various angles to deflect the heat in greater or less volume from the fire-box into the cooker, or to entirely close the opening 7 to prevent the passage of heat therethrough into the cooker.

11 designates a chamber in the cooker into which the passage 7 opens.

12 is a flue leading from said chamber alongside the main flue 1 to afford afidraft from the chamber 11 to cause the heat to flow from the fire-box into the cooker chamber 11. Said chamber 11 may be provided with a supplementary gas burner 13.

14 is an insulated oven chamber designed to serve a purpose similar to that of a fireless cooker chamber. It is arranged alongside the cooker chamber 11 and provided in all of its walls, excepting the wall which is presented to the chamber 11 with insulating material 15 of considerable thickness, so that the heat from said chamber 11 will be re tained so as to keep the chamber 14 warm.

The inside wall 16 of the fireless cooker chamber may also be provided with an insulating packing 15', the same being so constructed as to allow the fireless chamber 14 to become heated, but to avoid rapid radiathe flue 1. A plurality of these pipes or tubes are provided. The portions of the same that correspond to those just enumer- 1 ated, in a manner form an arch in the combustion chamber. Said tube 17 is provided at the top with a hot Water section d extending aslant downwardly in the direction indicated by the arrows on said section (1 to the right in Figs. 1 and 4, away from the section .0 and leading to one or more apartments, which are to be heated, as indicated in Fig. 5 1. From the nature of the views this downward slope is not shown in Fig. 4:. Said section (Z is preferably led above the ceiling of the apartment to be heated and thence downward through a drop sect-ion e to the heater section f in an apartment, and thence through a drop 9 to a heater section it in the lower apartment from thence to the lower section a of the tube, thus completing the circuit.

Each of the individual circulating tubes 17 will be of substantially the same char-. acter, it being understood that the number of sloping sections and drops will depend upon the number of apartments and the number of stories to be served by such tube. At the highest point of each of the water tubes 17, a pressure relief device is provided comprising a tee fitting 18, provided on its upper side with a funnel 19, opening therethrough to the atmosphere and provided with a seat 20 for a ball 21. Said ball is preferably of considerable weight and size and may be made of lead, iron, or other suitable metal of sufficient specific gravity. I regard a weight of about 2 pounds more or less to be satisfactory. The purpose of this weight is to form a closure for the passage through seat 20 and to allow the escape of the expanded water, and to prevent any danger of bursting the pipes. The surplus water caused by expansion under the effects .of heat will escape upward through the seat 20 around the ball 21 into the funnel and when the heat subsides the water from the funnel may seep back into the pipe. The ball may roll slightly to one side to allow the water to flow up into the funnel without being lifted bodily.

Preferably the funnel is made of sufficient capacity to hold a body of water which will supply the evaporation for considerable time, so that the water in the aipe need be replenished only at intervals of a considerable time. Said funnel may be made of suflicient size to contain two quarts more or less of water when the ball is in place.

The cooker 6 may be provided with various conveniences as a broiler 22, having gas burners 23 therein and opening through a door 2 1 into the cooker chamber 11, which is accessible through a door 25 from the inside of the house. By this arrangement the odors and smoke from food being cooked 7 on the broiler will be carried off through the fine 12.

26 is a heater for water for domestic use, the same may be so located as to be heated by the gas burner 13.

27 designates valves at the lowest points of the tubes 17 respectively for the purpose of drawing OK the water when occasion requires. Each tube is practically uniform in diameter so that the circulation of water will be at uniform speed throughout, thus scouring the interior of the tube and keeping it free from rust or scales.

In practical use the water tubes may be separately filled by pouring water into the funnel 19, for this purpose the ball 21 may be lifted out of the funnels until the water has risen into the funnels, then the balls may be replaced thus closing the tubes suiliciently to retain the water under considerable expansion from heat, then the fire at the burner 1 may be started into operation, thereupon the arch will become heated and water will be caused to circulate rapidly through the tubes, each of which forms a separate circulating system. By the construction shown there is no hindrance offered to the water and the same may circulate with such rapidity that it does not become materially cooled before its return to the arch after having passed through the chambers or apartments to be heated.

It is to be understood without illustration that the manner of introducing heat into the rooms may be by radiator or register of any approved form or pattern, or that the heat may be delivered directly by the uncovered pipe.

The burner 1 should be of sufiicient size to supply a flame large enough to completely surround the pipes in the chamber 41, said flame extending up along the tubes from one to twentyinches.

I claim 1. In a house-heating apparatus, the combination with a fire-box and fine, of a burner, a plurality of continuous individual watercirculating tubes, each being independent of the other and complete in itself and adapted for circulation of water, said tubes being bent inwardly at their lower ends to slant over the burner within the fire-box and extending upwardly through the fire-box and thence vertically above the burner, through the flue, and bent to extend laterally outside the flue and carrying upon their upper bent portions funnels attached thereto and provided with valve-openings, and spherical Weights reposing in said funnels and movably engaging said valve-openings to close the same.

2. A house-heating apparatus comprising a fine, a fire-box at the bottom of the flue, a tube extending through the flue from bottom to top and extending thence in the form of a loop to form an individual circulating system, said tube reentering the firebox at the bottom and being positioned within the fire-box to receive heat, said tube being provided at its uppermost portion with a funnel, and a spherical Weight seated in the funnel to allow escape of steam pressure from the tube.

3. A house-heating apparatus comprising a flue, a fire box at the bottom of the flue, a plurality of tubes extending through the flue from bottom to top and each being bent above the flue and extending thence in the form of a loop having a downward inclination at all points and each being continuous to form an individual circulating system, said tube reentering the fire-box at the bottom and being bent Within the fire-box so as to provide a chamber between the tubes in the fire-box, and a fluid fuel burner in the space between said bent tubes, the same being arranged to direct a flame against said tubes and up through the flue, each of said tubes being provided at its uppermost portion with a funnel and a ball seated in each funnel to allow escape of steam pressure from its individual tube, said funnel being arranged to allow the ball to roll to one side instead of being bodily lifted.

In testimony whereof, I have hereunto set my hand at Los Angeles, California, this 7th day of October, 1907.

MARGARET A. WILCOX.
