Specification of Letters Patent.
Patented JEeb. a, 1915,
Application filed Ju1y3, 1916. Serial No. 107,341.
To all whom it may concern:
Be it known that I, ELMER HARRISON, a citizen of the United States, residing at Chicago, in the eOunty of Cook and State of Illinois, have invented new and useful Improvements in Steam-Generators, of which,
the following is a specification.
This invention relates to steam generators designed for. house heating and similar purposes, where a low pressure of steam is required, and its object is to provide a steam generator from which a supply of hot water for domestic purposes may be obtained. v
The object stated is attained by means of a novel combination and arrangement of parts to be hereinafter described and claimed, and in order that the same may be better understood, reference is had to the accompanying drawings forming a part of this specification.
In the drawings, Figure 1 is an elevation of the appara-, tus, partly in section, and 1 Fig. 2 is an enlarged vertical section on.
the line 22 of Fig. 1.
Referring specifically to the drawings, 5 denotes a receiver or tank of upright cylindrical form, designed to receive steam from a boiler, the latter being located outside and alongside the receiver. The boiler is a cylindrical vessel 6 set vertically, and beneath which is located a suit-able gas or other burner 7. The vessel 6 has a bottom header 8 to which are secured fire tubes 9 extending upward into the vessel to such a height that the lowest water level in the vessel will cover the tubes. \Vhile the tubes 9 receive the heat rising from the burner 7 a central tube 10 extends from the header 8 and is designed to serve as a flue for carrying off the excess heat or odor from the burner, said flue extending entirely through the vessel 6, and passing through the top thereof for connection to a smoke pipe or other outlet.
Supported in the tank 5, by suitable brackets 11, is a closed pro-heating tank 12. A water supply pipe 13 passes through the side wall of the tank 5, and is connected to the bottom of the tank 12 to discharge thereinto. To the top of the tank 12 is connected an outlet pipe 14 which is coiled around the outside of said tank as shown at 15, and passes out of the tank 5 through the side thereof, and near the bottom, where it is connected to the casing 16 of a float-controlled valve 17. This valve is in the form of a puppet valve, having a thin, flat stem 18 rising from its back and extending into the float chamber of the valve casing where it is engaged by a spherical float 19, the latter normally resting on top of the stem and thus holding the valve open. The float carries opposed linked arms 20, whiclnfby means of slots 21 cooperating with a cross pin 22 through the valve stem 18, lift the valve to'closed position when the float rises. Pipes 23 and 24 connect the steam space of the vessel 6 with the tank 5. The pipe 23 extends from the vessel 6 to a T-coupling 25,a11d from the latter'the pipe 24 extends to the tank 5. i i
To the'co'upling 25 is connected an auto-- matic vfue l-controlling device comprising a casing'26 connected'by a pipe 27 to said coupling, and containing a flexible diaphragm 28 which is under the infiuenceof the steam pressure on one side of the diaphragm, and actuates a valve. Theother side of the diaphragm is engaged by the base 29 of a valve 30, the latter being in the form of a small plunger having cross slots 31, and slidably seating in a sleeve 32 mounted in an enlarged portion 33 on the top of the casing 26. Between the base 29 and the bottom of the part 33 is a spring 34 which opposes the flexure of the dia phragm 28 by the steam pressure, and moves the valve to increase the fuel supply when the pressure drops. The sleeve 32 is adjustably mounted on the part 33, it being threaded at 35 for this purpose, and its upper end is contracted to leave a chamber 36 in the part 33, to which an outlet pipe 37 is connected, said pipe leading to the burner 7. In the contracted portion of the sleeve 32 are apertures 32 which open into the chamber 36. Above the diaphragm 28, the casing 26 is entered by a fuel supply pipe 38. The gas or other fuel enters the casing 26 above the diaphragm 28 and flows through the cross slots 31 into the sleeve 32, from which latter it escapes through the aperature 32 into the chamber 36, and then passes to the burner 7 through the pipe 37. When an excessive steam pressure flexes the diaphragm 28 upward, the valve 30 is pushed upward into the sleeve, thereby reducing the effective area of the slots 31, and thus reducing the flow of gas to the burner. When the pressure drops, the spring 34 moves the valve back to increase the gas supply. The valve base 29 has a shoulder 39, which latter, when it strikes the part 33, prevents the fuel supply from being shut off entirely.
The tank 5 has a drain valve 40, and the pipes 13 and 14 are provided with unions 41 so that the tank 12 may be removed from the tank 5 after removal of the top of the latter.
The tubes 9 and 10 are secured to the header 8 by flanged sleeves 43, and the bottom of the vessel 6 has a reinforcing band 44, and also a flared marginal flange 45 to which the header 8 is clamped by a ring 46, whereby a water-tight joint is produced, and at the same time the header is readily removable for repairs, or for inspection of the interior of the vessel 6.
The float chamber of the valve casing 16 has anroutlet connection 47 with the vessel 6, and the coupling'25 has a connection 48 with the float chamber.
To the pipe 14, outside the tank 5, is connected a pipe 49'which leads to the various parts of the house where a hot water supply is desired.
To the top of the tank 5 is connected a steam outlet pipe 50 for conducting the steam to the radiators and other places of use.
In operation, the water being turned on, it enters the tank 12 through the pipe 13, and leaves the same through the pipe 14, and after passing through the coil 15 it enters the valve casing 16 and flows into the 7- vessel 6 through the pipe 47. When the water level rises sufficiently to operate the float 19, the valve 18 closes and shuts 01f the supply to the vessel 6. The steam generated in the vessel 6 passes into the tank 5 through the pipes 23 and 24, and is carried by the pipe 50 to the place of use. The steam in the tank 5 heats the water in the tank 12 and the coil 15, and these parts therefore serve as a feed water heater. The feed water is heated to such a. degree that it may be used for domestic purposes, a supply being obtained by the connection 49.
I claim The combination of a steam boiler, a receiver connected to the steam space thereof and having an outlet, a water tank in the receiver, a supply connection to said tank, and an outlet pipe establishing connection between the tank and the boiler, and having a portion which encircles the outside of the tank in a coil.
In testimony whereof I afiix my signature.
ELMER HARRISON.
