HARRY M. HILL, OF ST. LOUIS, MISSOURI, ASSIGNOR TO HILL ELECTRICAL MANUFACTURING COMPANY, OF ST. LOUIS, MISSOURI, A CORPORATION OF MISSOURI.
ELECTRICAL WATER-HEATER.
lSPE(JIFICACLION forming part of Letters Patent No. 727,361, dated. May 5, 1903.
Application filed May 10,1902. Serial No. 106,797. (No model.)
To all whom it may concern.:
Be it known that I, HARRY M. HILL, a citizen of the United States,residing at St. Louis, State of Missouri, have invented a certain new and useful Improvelnentin Electrical Water- Heaters,of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had io Io the accompanying drawings, forming part of this specification, in which- Figure 1 is a sectional View of my improved water-heater, showing the same in position. Fig. 2 is an elevational View of the insulation-head and its depending inner electrode, and Fig. 3 is a side elevational view of the adjustable outer electrode. Y
This invention relates to a newvand useful improvement in electrical water-heaters, the
zo object being to construct a device of the character described which is capable of adjustment whereby the temperature of the water heated can be regulated. This regulation is effected through the adjustment of one or the 2 5 other of the electrodes between which the water to lbe heated passes. These electrodes are preferably made of carbon and so constructed that they have contiguous faces arranged at an angle to the line of adjustment,
3o whereby when one of said electrodes is moved relatively to the other of said electrodes the proximate faces are caused to approach toward or recede from each other. By this adj ustment of the electrodes the'space in which the water is being heated is enlarged or diminished, also the overiiow or escape' ports of the heated water are adjusted, so far as their available area is concerned.
My present invention consists in the con- 4o struction, arrangement, and combination of the several parts of my device,all as will hereinafter be described and afterward pointed out in the claims.
In the drawings I have shown an apparatus operating upon the principle described in an application filed by me March 31, 1902, serially numbered 100,740.
In the drawings, 1 indicates a stand-pipe for water, the same being arranged in an or- 5o dinary pipe system. The upper end of this stand-pipe is shown as being curved to form a gooseneck, the end thereof carrying a spigot 2, manipulated by a handle 3. The spigotstem is provided with a key ,fitting in a slot in a switch-stem 5, said switch beiuginclosed in a casing 6, supported bya bracket 7 upon the stand-pipe.
y Referring toFig. 1, 9 indicates a coupling which is screwed in the lower end of the spigot, into which coupling is fitted a head 1l, made of insulation material. 12 indicates a fianged boss secured to the under side of the head 11, said coupling 9, head 11, and anged boss 12 being provided with alining openings for the passage of water. A wire 8 65 leads tothe flanged boss 12. The purpose of thus separating the coupling 9 and the anged boss 12 is to insulatethe apparatus from the water-pipe.
13 indicates an electrode which for the sake 7o of distinction will be termed the inner7 electrode, the same being provided with abore for the passage of water, whereby the water is caused to pass downwardly through this inner electrode and thence upwardly through the space between the same and the outer electrode, (indicated at 14.) The inner electrede, as shown in Figs. 1 and 2, is substantially conical in shape-'that is, its outer periphery is formed tapering. 8o
15 indicates a threaded flange secured to and depending from the insulation-head, said flange being provided with a seriesof openings 16, arranged under the insulation-head.
The'outer electrode 14 is formed with a ta- 85 pering recess or pocket designed to receive the inner electrode. The lower end of the outer electrode is formed solid or imperforate, so as to force the water issuing from the bore in the inner electrode to pass upwardly between the inner and outer electrodes and overflow the upper edge of the outer electrode. The upper portion of the outer electrode is encircled bya metallic band 17, which is designed to be threaded into the flange 15. 95 In order to. make good electric contact between the flange 15 and the band 17, I provide a yielding tongue 18 on said band, which is designed to contact with the outer periphery of the flange 15. Thus I do not rely en- Ioo t? da tirely upon the contact made by the threads, which contact is liable to be aifected by the corrosion of the metal. This tongue also serves to frictionlessly lock the outer electrode against unintentional displacement.
19 indicates a screw whose function is to secure the band to the outer electrode and whose head provides a stop to limit the upward movement ot' the outer electrode.
8 indicates a wire leading from the switch to the inner electrode, and 2l indicates a wire also leading from said switch to the flange 15 and its electrically-connected outer electrode.
22 indicates a housing which is received in a concentric groove in the insulation-head, said' housing being of larger diameter than the outer electrode, so as to provide a passage for the heated Water. This housing is slotted for the reception of a thimble 23, through which the wire 21 passes. The opening thus provided affords a suitable vent to accommodate the displacement of the air when the water is turned ou and also enables steam to escape should steam be generated, and this relieves the water between the electrodes from back pressure due to the generation of such steam and prevents the water from becoming turbulent and spitting7 In operation the admission of water to the heater by turning the spigot throws the switch and completes the circuit. The water passes downwardly through the bore of the inner electrode and thence upwardly in the space between the inner and outer electrodes, by which it is heated. The water overiiows through the opening 16 and is received in the housing, the same discharging through the opening in the bottom of said housing. If it is desired to heat the water extremely hot, the outer electrode is screwed up, so as to cause the proximate faces of the inner and outer electrodes to -closely approach each other, which adjustmentof the outer electrode also reduces the space occupied by the water during the time it is being heated and reduces the available area of the openings 16, so that the overiow is retarded and the water being heated is held a longer time between the two electrodes. In this manner it is possible with my present construction to heat water up to the boiling-point; but of course when the device is thus adjusted the output of heated water is much smaller than is the case where water at a lower temperature is desired, and the outer electrode is adjusted outwardly or downwardly, so as to increase the available area of openings 16, increase the space between the electrodes occupied by the water being heated, and also increase the distance between the proximate faces of the electrodes. The value of this adjustment can be readily appreciated when it is understood that the same renders my improved device capable of various uses where it is desired to get hot water at varying degrees of temperature from a current of electricity of given voltage. Furthermore, it has been found that different waters require different electrical treatment to be heated, and by this adjustment my device is adapted for heating all kinds of Water, it being only necessary to determine the temperature required, when the outer electrode can be adjusted inwardly to meet the demands of the particular kind of water being treated, the electrode being left in its final position when the temperature of the water being treated reaches the desired point.
I am aware that many minor changes in the construction, arrangement, and combination of the several parts of my device can be made and substituted for those herein shown and described without in the least departing from the nature and principle of my invention.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
