ELECTRICAL WATER-HEATER.
To all whom it may concern:
Be it known that I, HIRAM D. 001), JR, a citizen. of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Electrical.
ater-Heaters; and I do hereby declare the following to .be a'full, clear, and exact description of the invention, such-as will enable others skilled in the art to whichv it appertains to make and use the same.
My invention has for its object to provide it a simple and highly efficient instantaneous electrical water heater, especially adapted for use at soda waterlfountains, bars, and
various other places where it frequently necessary touse small quantities of hot water in the mixture of drinks,and for similar purposes.
To the-above ends, the invention consists of the novel devices and combinations of devices hereinai'te'r described and defined in the claims.
In the accompanying drawings which illustrate the invention, like characters indicate like parts throughout the several views.
Referring to the drawings: Figure l is a view .in elevation showing the improved water heater; Fig. 2 isa vertical section taken on the line 09 m of Fig. 1,
some parts being left in full, some parts being broken away, and some parts being removedyFig. 3 is a plan view of the water heater proper, with the top plate thereof removed; Fig, 4 is a vertical section through the water heater proper onthe line w a of Fig. 3; and Fig. 5 isa diagrammatic. view showing circuit connections to and from 'the coil of the water heater.'.
The numeral. 1 indicates a wa'ter containing tank, which is preferably of cylindrical form and constructed of glass, so that the purityofthe water contained therein may be seen from the exterior. This tank or glass jar is shown as provided with aglass cover 2, and it is seated within the upper portion of a sheet metal supporting base 3 having legs 4:.
The heater proper may take difierentforms,

but as illustrated in the drawings, and as preferably constructed, it is made up of two disk-like sections 5 andG, to-wit, a lower body j lsecured on the bottom of the body plate 5,
section 5 and a top or cover section 6. These Patented May 24, 1910.
Application filed April 5, 1909. Serial No. 488,664.
as porcelain. The lower or body member 5 is formed in its upper face with an involute. or-spiral water conduit or channel 7, the 111- nor extremity of which terminates in a centrally located chamber 7*. The entire inner surface of the-conduit 7 and chamber 7* ,is
lined with an -insulating material, suchpas porcelain 8, \VhlCll is glazed or otherwise permanently formed or securedthereto.
The under surface of the top plate, discovered with the same insulating material indicated at 9. .These-inaterials or coatings 8 and 9, make the entire internal-surface of .the involute or spiral channel a non-condoctor of electricity and a very slow radiator of heat. p The inner extremity or'chamber 7 of the conduit? is connected to' the interior. of the' tank 1, by a small'tube 10, that is extended upward through a perforation in the top plate of the metal base 3, and through a perforation in th bottom of the tank 1. The lower end'ot tie tube 10 is screwed into ahub 11 of the top plate 6, and thelatter' is metal base 3. '.Tl10 'upper end of the tube screwed into the hub of the top plate of the 10 is threaded and provided with-a nut '12,
that clamps a pliable washer 13 against the bottom of the tank, and'thiis forms'a water tight joint. The plate 6 is secured to the base or body member 5 .by screws 14 or other suitable devices, and a watertight joint is formed between the said membersoand 6.
A faucet 15 is secured to one side of the -metal base 3, 'and is connected by a short pipe 16 to the outer portion of the conduit "7, being-as shown, screwed intoone side of the, body member 5.
Located with n the spiral conduit 7 landextending from the inner tothe outer portion thereof, is a cylindricallycoiled wire or electrical conductor 17, of high electricalresistance, being preferably made of German silver. ,The coiled w re or conductor 17, like the conduit 7 is, in t'liis'preferred form of the heater, of course, bent longitu dinally into; spiral or approximately in? voluted form. Its inner extremity is connectedto a binding post 18, andits outer extremity is connected to a binding post-19, both of which binding posts, as SlIOWD HIQ and areinsulatedtherefrom.
The numeral 20 indicates a small electric conduit 7, so

lamp, and the numeral 21 an electric switch, both of which, as shown, applied to one side of the metal based.
The numerals indicate respectively, the positive and negative sides of the supply circuit connected to the binding posts 18 and 19 spectively.
The switch 21 is interposed in the wire 23 is arranged to simultaneously open and simultaneously close the circuit through the coil 17 an through the lamp circuit2 l.
As is evident, when the faucet 15 is open, Water from the tank 1 will run to the faucet through the spiral conduit 7, and through and around the convolutions of the heating coil .17, and will thus be brought or kept in contact with the said heating'coil. The form or" the coil 17 also exposes a very large amount wire to the water that is being heated in its passage through the conl l hen hot water is required, the electrical current must, of course, be turned onto the heating 'coil 17. dl hen the current is turned on and the faucet is open, as above stated, water running from the tank to the faucet will be heated to a high temperature while it is passing through the that this device affords what may be designated as an instantaneous water heater, that is, an apparatus in which the water is heated while flowing from the point of supply to the point of discharge.
As is evident, an electrical water heater of the kind above described, ..ill be found highly eiiicient and extremely'desirable at soda water fountains, bars and numerous, "other places where small supplies of hot water are frequently required, but where the demand does not justia y the maintenance of a continuously heated body or" water. The heater, is however, capable ot' being made in very large as well as very small sizes, and is capable of general use. For domestic purposes and house use, and in resta'iirants and hotels, it will also be found an extremely convenient water heating aparatus. When made in the required size, it would afiord an eflicient heater for bath purposes, or general kitchen use.
While, the spiral or approximately involute form of the water conduit or channel is preferred, it will, of course, be understood. that the said conduit or channel may take other forms. For instance, it might be in the form of a manifold.
What I claim isf 1. In an electrical water heater, the combination with a two-part member having a Water delivery conduit with ilnp'orforated walls and open ends from end to end by-separation of the sections of said member, of an electrical conductor placed within and extending l0ngitudinally of said conduit, substantially as described.
Q. In an electrical water heater, the combination with a. two-part member having a long tortuous water delivery conduit'with imperforated walls and open ends adapted to be opened up from end to end by separation of the sections of said member, of a coiled electrical conductor placed within said conduit and extended longitudinally thereof, substantially as described.
In an electrical water heater, the combination with a water tank, of a member located at the bottom of said tank and having a long tortuous water delivery conduit with impertorated walls and open ends connected to the bottom of said tank at its inner end portion, a faucet connected to the outer end portion of said conduit, and a coiled electrical conductor located within and lon-- p'itudinally of said conduit, substantially as described.
in testimony whereof I atliiz my signature in presence of two witnesses.
