Electrical water-heater.

Application filed April 6,1905. Serial Ho. 254,142.

'To all whom it may concern:

Be it known that I, William A. Brown, a citizen of the United States, residing at Oakland, in the county of Alameda and State of 5 California, have invented new and useful Improvements in Electrical Water-Heaters, of, which the following is a specification.

My invention relates to a device for heating water by means of an electrical current io and a device by which, a resistance is produced to raise the, temperature of the water in the containing vessel.

. It comprises combinations of parts and de tails of construction, which will be more fully 15 explained by reference to the accompanying drawings, in which—

Figure 1 is a sectional view of my device.' Fig. 2 is an outside view of a corrugated tube.

It is the object of my invention to provide 20 a means for rapid heating'of liquids by the immersion of the heater mechanism within the liquid.

As shown, in the drawings, A is a hollow tube having perforations in its sides, as shown 25 at 2.

is the part through wliich heat is communicated to the water. This part is here shown in the form of a bar of smaller diameter than the interior of the tube and having 30 grooves, channels, or corrugations of any desired character formed Upon its surface, the object being in aiiy construction to make as large a contact-surface for the water as possible. The ends of this bar are provided 35 with non-conductors, as at 4 and 5. The non-conductor 4 is of such greater diameter than the bar that it prevents contact of the bar With the sides of the tube near one end. The other non-conductor , 5 forms an insula40 tioii between the bar and the bead 6^:, which fits into one end of the tube.

represents the conducting-wires' which are connected with the opposite poles of a source of electrical energy, and one of these 45 wires'is connected with the head or cap 6 and the Other with the bar 3. As these parts are not in direct elebiricai 1·.ίι: mmuca.tion, it will be manifest that the electrical current passing through the circuit must include as a .meafis of transmission a body of water which 50 is inclosed within the tube A and which forms the resistance. The Water is constantly circuiting through the tube by reason of the openings in the side of the tube, which may also be corrugated, if desired. 5,5

A device thus constructed may be immersed in any vessel containing, water, and the water will be heated to any desired temperature in a short space of time.
