HEATING APPARATUS.
Application filed May 21, 1927. Serial No. 193,157.
. This invention; relates to heating systems and has particular reference to means for electrically heating water for hot-water or steam radiator systems in order to eliminate coal or oil burning furnaces with the at tendant inconveniences thereof.
The invention comprehends a heating system including steam or hot-water radiators and a boiler having a heating chamber extending into the same from one of its walls in which an electric resistance heating device is remoiably positioned for transmitting heat to the chamber walls'forheating the water within the boiler.
The invention furthermore comprehends means for controlling the heating element in order that a maximum degree of heat may be obtained when initially starting the system and whereby subsequently the temperature may be reduced for maintaining a suflicient temperature in the system.
Other objects reside in the general simplicity of construction, the'economy with which the same may be produced and installed, and the general efliciency derived therefrom.
With the above recited and other objects in view, reference is bad to the following description and accompanying drawings in which there is exhibited one example or embodiment of the invention, while the appended claim defines the actual, scope of the,
invention.-
In the drawings Figure 1 is a diagrammatic view of a heating system made in accordance with the invention; 7
Fig. 2 is an enlarged fragmentary sectional view of the boiler and heating device therefor.
Referring to the drawings by characters of reference, 10 designates diagrammatically a radiator'either of the hot-water or steam type. to which the hot water or steam is supplied by a feed pipe 11 leading to a boiler 12 and from .which radiator a return pipe.
13 leads to the boiler 12. The boiler is preferably installed in a recessed wall cabinet 14 and is provided with the usual. gage 15 for observing the amount of water contained in the boiler and is also equipped with a steam gage 16. A su ply pipe 17 having a valve 18 leads to the oiler from a source of supply whereby the water supplymay be replenished when necessary. The boiler is provided with a substantially tubular casing 19 extending inwardly from one nt' its walls and provided with a closed inner end 20 and an open interiorly threaded outer end 21 which opens through the wall of the boiler, the said casing defining a heating chamber 22. An electrical heating device is adapted to be removably positioned within the heating chamber 22 and said device consists of a substantially cylindrical body 23 of insulating material, which is carried by a plug or head 24. The plug is exteriorly threaded at 25 for detachable association with the interiorly threaded open outer end of the casing 19. The tubular body 23 is wound with resistance wire 26 preferably arranged thereon in spiral configurations with the outer end connected to a conductor wire 27 leading from a central binding post 28, which is connected by a conductor wire 29 to one pole of a source of supply. The other pole of the source of supply is connected by a conductor wire 30 to a movable switch arm 31, which is designed for selective engagement with a pair of contacts 32 and 33. The contact 32 leads to a binding post 34, which is connected by a conductor wire 35 to the inner terminal of the coiled resistance wire 26. The, other contact 33 is connected by a conductor wire 36 with a binding post 37, which binding post is con nected by a conductor wire 38 with substantially the medial configuration of the resistance wire winding 26. It thus follows in practice that when the switch arm 31 is engaged with the contact 32, the full resistance wire winding 26 will be heated to generate the maximum heat within the heating chamber 22. The walls of the heating chamber will in turn heat the water within the boiler 12 and in the case of a steam system will generate steam in the upper portion of the boiler which. will be conveyed by the pipe to the radiator .10. After steam has been initially generated. the switch arm 31 may be thrown over on to the contact 33 so that approximately only half of the resistance wire winding 26 will be activated, this, however, being sufli-"ient to maintain a head of steam in the boiler.
From the foregoing it will thus be seen that a heating system has been devised which employs the electric house current as a means for generating steam or hot water 4 A water heater comprising a boiler, a tubular casing extending into the boiler from one of its ends, said casing having an open outer end and a closed inner end defining a heating chamber submerged in the water in the boiler, and an electric resistance heating device removably positioned within the easing and closing the outer end of the same to transmit the heat generated within the chamber through the chamber walls to the water in the boiler, the said electric resistance heating device including a base of insulating material constituting a plug having detachable threaded engagement within the outer open end of the casing for closing the same, a tubular inwardly projecting member of insulating material carried by said base. an electric resistance element helically wound upon said tubular member, a common feed conductor connected with said winding at the inner end, a pair of return conductors connected respectively to the outer end and to a point intermediate the ends of said winding, a common return conductor, and a switch including a pair of contacts and a movable switch arm.
