WATER-HEATER.
SPECIFICATION forming part of Letters Patent No. 765,338, dated July 19, 1904. Application filed August 25,1903. Serial No. 170,675. (No model.)
To all whom t may concern.-
Be it known that I, ALEXANDER D. GORDON, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in VVater-Heaters, of which the following is a specification.
This invention relates to a water-heating apparatus or attachment for domestic and other boilers or water-reservoirs, and comprises a reservoir or water-heating chamber or receptacle, a gas-burner for heating the same, and a thermostat which is controlled by the temperature of the water and the supply of gas to the burner.
One object of the invention is to provide a practical efiicient water-heating attachment of simple and inexpensive construction which is complete in itself and can be readily applied to the ordinary boiler or water-reservoir.
Another object of the invention is to provide the attachment with simple and convenient means for adjusting the automatic Valve of the gas-burner to regulate the supply of gas to the burner.
In the accompanying drawings, Figure 1 is a vertical sectional elevation of a water-heater embodying the invention and showing by dotted lines a boiler to which the same is applied and an inclosing casing for the boiler. Fig.
2 is a horizontal section, partly in plan, in line 2 2, Fig. l. Fig. 8 is a fragmentary vertical section of the gas-burner, on an enlarged scale, in line 3 3, Fig. 2.
LikeA letters of reference refer to like parts in the several figures.
A represents a water-heating chamber or receptacle which is provided at its top with a short pipe or tubular coupling B, by which the heating-chamber is connected to the boiler or water-reservoir O. (Indicated by dotted lines A in Fig. 1.) The'heating-c'hamberislocatedbeneath the reservoir, and the coupling is screwed into the threaded central hole in the bottom of the reservoir or detachably secured thereto in any other suitable manner. The heatingchamber is preferably cylindrical and is provided exteriorly with radiating projections or portions to increase the area of the heatingsurface and serve as baiiies to prevent a too which regulates ready escape of the flames from the burner. The heating-chamber is divided by a vertical annular partition Z into two concentric compartments CZ (Z2, which communicate at their lower ends. for which purpose the partition preferably terminates above the bottom of the heating-chamber. The inner or descending compartment d of the heating-chamber communicates directly with the water-reservoir through the tubular coupling, and the upper end of the outer or ascending compartment Z2 communicates indirectly therewith through the coupling andv a hole or holes E in the upper part of the annular partition.
The heating-chamber is preferably provided at its lower end with a drain or draw-off pipe c, having a faucet L The gas-burner, which is arranged beneath the heating-chamber,is constructed as follows: F represents a burner casing or body which is substantially cylindrical in form and is didivided by a horizontal partition into a lower or valve chamber f and an upper or gas-distributing chamber f, which communicate through a valve-controlled opening f2 in the partition. The valve-cham ber is provided with a removable bottom or screw-cap g. H indicates the gas-supply pipe, which communicates with the valve-chamber and is provided with the usual valve.
I represents upright burner tubes or nozzles, which are arranged around the lower portion of the heating-chamber and are connected by radial pipes or couplings ci with the distributing-chamber of the burner-body. The burner-nozzles are of the well-known air and gas mixing type, and the outlet-oriiices at their upper ends face toward the heating-chamber to direct the flames against the outer surface of the latter. Any desired number of burnernozzles may be employed, and, if preferred, the cylindrical wall of the distributing-chamber may be provided with additional openings closed by removable plugs to facilitate the attachment of additional burner-tubes.
J represents a pilot-burner which connects directly with the gas-receiving chamber of the burner-casing and is provided with a regulating-valve j.
K represents a tubular nipple or coupling IOO screwed intoa central threaded hole in the lower end of the heating chamber. The burner body is adjustably connected to the nipple K by an adjusting-sleeve L, which is externally screw-threaded and screwed into a threaded hole Z in the burner-body. The adjusting-sleeve is also internally threaded and screwed on the screw-threaded lower end of the nipple K. One thread of the adjustingsleeve is a left-hand thread, while the other is a right-hand thread, so that when the sleeve is turned the burner-body is moved toward or from the heatingchamber, according to the direction of rotation oi' the adjusting-sleeve. The latter is provided with a portion Z', which is fashioned to enable it to be readily turned by hand or with a suitable tool.
M represents the gas controlling valve, which is arranged in the valve-chamber of the burner-body and is provided with an upper conical face, which seats against a corresponding conical Jface surrounding' the opening f2 in the partition which forms the top of the valve-chamber. The valve is retained in position and guided in its movements by upper and lower upright stems m m', which respectively engage loosely in the bore of the nipple K and a guide-hole. in a boss m2, rising from the removable cap ot' the valve-chamber.
The valve is pressed upwardly to its seat byone or more springs N, arranged between the valve and removable cap. The spring, which is preferably made from thin spring metal, is secured on the lower stem of the valve by a nut n and has projecting radial arms which extend downwardly and bear at their free lower ends on the removable cap. The described spring is preferable to a coil spring or springs, as it holds the valve from tilting and seating unevenly. As the valve is located in the lower chamber of the burner-body and seats upwardly, the gas-pressure in the valvechamber and the spring hold the valve to its seat and prevent any leakage of gas past the valve when the water in the reservoir has been raised to the desired temperature and the valve closed.
O represents an expansible or thermostat tube, which is screwed at its lower end into a threaded hole in the nipple K and extends up through the inner compartment of the heating-chamber and tubular coupling into the boiler or water-reservoir. rlhe upper end of the thermostat-tube is closed and is connected to the upper end oi' avertically-movable valveoperating rod 79, inclosed in the thermostattube and bearing at its lower end on the top of the upper stem of the gas-valve, whereby the valve is opened and closed more or less by the contraction and expansion of the thermostat-tube.
In operation the water is quickly and highly heated in the heating-chamber and passes up through the coupling B into the reservoir, displacing the cooler water therein, which passes down through the coupling into the heating-chamber, where 1t also circulates from one compartment to the other by means of` the communications at the upper and lower. .ends of the compartments.
The water is thus kept in circulation from the water-reservoir to the heating-chamber, through the two compartments of the latter, and back to the reservoir through the coupling B, and the entire volume ot' water in the boiler or tank is soon raised to the desired temperature. As the temperature of the water in the boiler or reservoir rises the thermostat-tube expands and permits the valve to close more or less under the action of its spring, and as the temperature or' the water falls the thermostat-tube contracts and opens the valveto a greater or less extent, thus controlling the flow of gas to the burner and maintaining the water at the desired practically constant temperature. The extent to which the valve is opened, and
consequently the heating flames, can be l quickly and easily regulated by turning the adjusting sleeve, and thereby moving the burner-body and valve toward or from the valve-operating rod. The apparatus comprising the heating-chamber, burner, and thermostat is complete in itselil and can be applied with little labor and expense to the ordinary household boiler or other water-reservoir.
The described construction and arrangement of the heating-chamber necessitates but a single connection with the water-reservoir or boiler', thereby minimizing the cost of the apparatus and labor of attaching the same to the boiler or water-tank.
The boiler or reservoir and the heating attachment are usually inclosed by a jacket or casing Q,(indicated by dotted lines in Fig. 1,) which coniines the products of combustion around the boiler to heat the latter and leads the same to a suitable iiue or chimney connected to the jacket.
I claim as my invention- 1.
