To all whom it may concern 4 Be it known that I, CHARLES J. REILLY,

a citizen of the United States, residing at Catskill, in the county of Greene and State of New York, have. invented. a certain new and useful Improvement in Furnaces for ;Water-Heaters, of which the following is a specification.

This case is a divisional application of 1N0. 858,603, Charles J. Reilly, water heater,

filed Aug. 26, 1914.

My invention relates to furnaces for water heating, devices, particularly such as are adapted for the use of various kinds of oil,

such as kerosene, as fuel.

One form of my invention is illustrated in theaccompanying drawings wherein- Figure 1 15 a diagrammatic side elevation, with parts showing on dotted linesFig. 2

is a cross section of the heater,Fig. 3 is a plan section of the same, as indicated on line 3-3 of Fig. 2,Fig. 4 is a perspective ofthe air valve ringFig. 5 is a vertical cross section of the generator.

Like parts are indicated by the same letter in all figures.

. For purposes of illustrationI have shown.

my invention in connection with an ordinary range or furnace hot water b01161, which may be an ordinary receptacle for holding hot water under pressure. In view r of the necessity of such device for use in heating water in the household, "and for many commercial purposes in thermal districts, cities, towns and villages, where no M artificlal or natural gas can be secured'for the purpose, and where gasolene if used for the purpose is dangerous to life and property, I have invented an arrangement in which ordinary kerosene or crude oil can be used for the purpose efficiently without fear of any danger, externalheat or obnoxious odors. The greatest benefit will be derived in many cases by those who have a water heating apparatus connected'to a furnace or coal cook stoves, only used for a few monthsv in each year, thus necessitating resorting to I laborious and troublesome means of secur= the furnace.

' ing hot water for the bath or other household or commercial purposes. My invention can be connected up with, and withoutdisturbing any other arrangement for heating B is a cylindrical heater housing containing-the heating coil B whence leads the pipe 0 C respectively tothe top and bottom of the receptacle A. The heaterB is connected with the source of fuel supply D, the fuel in this case being'kerosene, by means of the-pipe E, which leads downwardly from the reservoir and passes through the wall of F is a valve to regulate the quantityof oil passing through the pipe E. V

G is a generator, the essential part of which is the annular part G with screw threaded hollow projections, Gr on its opposite sides and a central'plate G Into one of these connections G leads thev pipe E J and from the other emerges the pipe G which is shaped as shown and terminates in the cap H, perforated to allow theliquid in the pipe-to escape andplaced beneath the plate G Thisplateacts as a baffle to distribute the upwardly flowing gas. a g The furnace consists of the casing K, with the fire brick lining I. a

J J are perforationsthrough the casing and fire brick lining I. g

J J are perforations in the valve ring L, which is supported in the annular support M, and whose two ends are adapted to be drawn together by the thumb screw N to lock it in any desired position. The quan-.

tity of air is regulated by moving and setting this valve ring. V

In the heater housing B is the coil B connectedwith pipes .C at top' and bottom as indicated. I use a double conical coil as indicated with the baffle plate P at the middle and narrowest portion to prevent the hot gases from passing up through the Gen ter of the coil. 7

loose bed of asbestos U to absorb the oil that is allowed to run out of the perforation in the cap H for use inheating up the generator in starting up the apparatus V is a tube leading from the water circulating pipe C down to just above the baffle plate of the generator, and it is controlled by the valve V. Through it water may be discharged upon the baflie plate.

X is an auxiliary reservoir and Y a valve connected with the pipe E, whereby the supply of kerosene may be cut off when the auxiliary reservoir is full, the latter being a charge for a specific piece of work or time.

Z is the cold water inlet pipe which leads I to the bottom of the receptacle A, and Z the hot water service pipe which leads from the top thereof.

Z is a stand or bracket on which the receptacle is supported, and Z is a like stand or bracket on which the furnace is supported.

X is a check valve or air release communicating with the reservoir X to permit air to enter at the top to displace the liquid which runs out when the valve Y is shut and the valve F is open. It, however, does not permit the discharge of oil'when the system is full.

The use and operation of my invention is as follows: The cold water and the hot water pipes are connected to the distributing system of the house in such manner that the receptacle stands full of water, and under normal conditions this water will be cold. If now, the operator desires to heat the water, he will turn the valve ring L so as to expose the interiorof the furnace. He will then open the valves Y and F sufliciently to allow oil to enter through the pipes E and G to the interior of the furnace and into the bed of asbestos U in the bottom of the furnace. He now closes valves Y and F, and by match or taper lights the oil in the asbestos within the furnace, and this oil burning will bring the generator to such a temperature as will cause the formation of gas. The operator now opens the valves Y and F, whereupon the oil which passes through the pipe E into the generator emerges from the cap H as gas, and as such it is immediately burned.

The products of combustion pass upwardly through the top of the furnace, through the heater, and 1f the damper S is open, out through the stack and chimney into the open air. Such products of combustion however, pass laterally upwardly through the coils B being deflected by the baflie plate P, so that at that point all of the products of combustion will have passed through the lower set of coils and thereafter will pass inwardly through the upper set of coils, thus heating the water which passes through these coils.

If the operator desires to heat a certain specified amount of water or to have the apparatus run for a predetermined period, he will open the valve Y, or otherwise manipu late the valves so that the auxiliary reservoir X fills with oil, and he may then close the valve Y and proceed as above, whereupon the tire will be maintained only so long as the oil in the auxiliary reservoir lasts.

In apparatus of this kind trouble is frequently experienced with respect to the formation of soot and like deposits on the coils. For this reason I provide the pipe V and controlling valve 7, so that when the valve WV is open a certain amount of water will pass through the heater and be discharged upon the hot baflie plate G when it is im mediatcly converted into steam, and this steam serves to clear the exterior surfaces of the coils of the deposits thereon due to the passage of the products of combustion.

I claim:

1'. The combination with a combustion chamber of a gas generating coil located in said chamber above the air supply, a heating and deflecting plate integral with the coil, :1. burner located beneath said plate, a gas supply pipe leading from the generating coil to said burner, an oil supply pipe communicating with the generator, and means for discharging water in a liquid form upon the upper surface of said plate independent of the gas and oil supply.

2. The combination with a combustion chamber having an absorbent wick-like bottom, of a gas generating coil located in said chamber above the air supply, a {heating and deflecting plate integral with the coil, a burner located beneath said plate, a gassupply pipe leading from the genera-ting coil to said burner, and an oil supply pipe com municating with the generator, and means for discharging water in a liquid form upon the upper surface of said plate independent of the gas and oil supply.

3. The combination with a combustion chamber having an adjustable air supply, of a gas generating coil located in said chamber above the air supply, a heating and deflecting plate integral with the coil, a burner located beneath said plate, a gas supply pipe 1,159,090 7 s r v 3 leading from the generating coil to said in the presence of tWO Witnesses this 24th burner, and an oil supply pdilpe communicatday of October 1914. 1 ing With the generator, an means for dis charging Water in a liquid form upon the a a H L REILLY 5 upper surface of said plate independent of Witnesses-z Y the gas and oil supply. v 'A.
