ELECTRIC HEATER Filed July l0, 1931 Isaac Party/naw INVENTOR Patented Mar. 27, 1934 STTES ELECTRIC -EA'IER This invention relates to electric heaters and has for one of its objects the provision of an electric heater adapted to be attached to a faucet and to an electric power circuit, the current from the mentioned power circuit adapted to heat water as it passes between electrodes employed in the heater.

Another object of the invention is the provision lof an electric heater adapted to heat water rapidly during its passage from a faucet through the heater, the Water being in continuous motion.

Other objects of the invention will be appreciated from a reading of the following specification.

The invention will be fully and ccrnprehenu sively understood from a consideration of the following detailed description when read in connection with the accompanying drawing w" h forms part of the application, with the und standing, however, that the improvement is capable of extended application and is not conn ned to the exact showing or the drawing to the precise construction described and, therefore, such changes and modications may be made therefrom as do not affect the spirit of the vinvention nor exceed the scope thereof as expressed in the appended claim.

In the drawing:

Fig. 1 is a plan view of the heater, parts being broken away, the view showing certain parts in section; and

Fig. 2 is a vertical section taken on line 2-2 lof Fig. 1.

Referring to the drawing for a more detailed description thereof, the heater comprises a receptacle or container 5 having a removable bottom 6 and a spout '7 having a passageway 8 therethrough to serve as the outlet of the container.

Means are provided for attaching the heater to a faucet 9, said means comprising a hollow member 10 having an annular flange 11 at its upper end, said flange being bent over to the interior of the member 10 forming an interior annular flange 12 spaced from the outer flange so that a tubular member 13 of rubber may be held between the mentioned flanges. The hollow member 12 is swivelly connected to a tube 14 which extends through the top and bottom walls of the container. The tube 14 is adapted to convey water from the exterior to the interior of the container. The same tube is provided with outlets 15 so that water or other liquid which is to be heated may flow out from the tube into the container. The water passes between electrically conducting electrodes 17 and 18 and be- (I 21S-Grill tween electrode 18 and a similar electrode 19, the mentioned electrodes being in the form of discs. Electricity news through the water between the discs and thereby heats the water, the heated water, due to the continual flow of incoming water, rising in the container until it reaches the outlet S through which it flows to the exterior of the container for use.

The lower end of the tube i4 is threaded to receive a nut 21, the lower end of which is flush with the lower end of the removable bottoms 6 of the containers. The device may be attached to the faucet 9 by means of a chain 22, secured at both ends to the flange il of the hollow member le, the chain being adjustable by reason of the tact that suitable link may be connected to opposite pins 23 extending from the mentioned ange 11.

Belts 2li and 25 pass thrigh the mentioned discs 1*?, 13 and 19, the lower ends oi' said bolts resting on the bottom 5 of the container, nuts 26 and 2? being threaded respectively on the bolts and n electrically conducting washer 28 disposed between the head 29 of the bolt 2e and upper suriace of the disc 17. An insulating washer Si) encircles the bolt 2e and lies between the lower surface of the disc 1'? and the upper surace of the disc i8 to separate these discs. An insulating sleeve 3i encircles the bolt 2e within the disc 18 to insulate this dise from the bolt 2a. fin insulating washer 32, integral with the insulating sleeve 31 lies between the discs 18 and 19 to separate the saine. An electrically con ducting sleeve 33, contactingly eli-circles the bolt 2e within and touching the disc i9, the lower end of the sleeve 323 contacting with an electrically conducting washer 34. An electrically conducting wire is held by the nut 25 against the washer 34; and in Contact with the bolt The discs 1'7 and 19 are thus electrically connected with the bolt 24 while the disc 18 is insulated :ir-om the bolt 2:1. An insulating washer 32 lies between the head 39 oi the bolt 25 and the upper surface of the disc 19, insulating sleeve 39 which is integral with the disc 38 encircling the holt 25 within the disc 17. An insulating washer 40 encircling the bolt 25 lies between the disc 17 and 1S. in electrically conducting sleeve il contactingly enc" les the bolt 25 within the disc i8,

this sleeve be c, in contact with this disc so that the same is in electrical communication with the bolt 25. An insulating disc i2 lies between the discs and 19 and encircles 'the bolt 25. An insulating sleeve 4B encircles the bolt 25 within the disc i9, an insulating disc 4.4, integral with the insulating sleeve 43, lying against the lower surface of the disc 19 and encircling the bolt 25. An electrically conducting washer 45 lies against the lower surface of the disc 44, an electrically conducting wire 46 being held between the disc 45 and the nut 27 by the latter, the wire 46 being in contact with the bolt 25. The

discs

17 and 19 are thus insulated from the bolt 25 while the intermediate disc 18 is in electrical communication with the bolt 25.

The

wires

35 and 46 are respectively connected to threaded

terminals

47 and 48, said terminals being held in position by

nuts

49 and 50, respectively.

Thc terminals

47 and 48 are adapted to be connected to a source of electrical power so that when there is water between the discs 17 and 18 and between 18 and 19, an electric current will flow through the water between the discs to heat the water.

lt is to be understood that any desired number of electrodes may be employed, the current consumption increasing with the number of electrodes.

What is claimed as new is:

An electric water heater comprising a casing having a discharge in communication therewith at its upper end, a pair of terminals, a plurality of spaced disks of low electrical conductivity connected to said terminals, said disks being disposed adjacent the bottom of the casing and formed with central openings, a. tube extending centrally through the casing and through the central openings in said disks and formed with ports or openings in the zone of said disks, and means for coupling said tube to a water spigot to carry water to the container through the tube and through the openings in the latter for contact with said disks, the tube having a swivel connection with said coupling,` means to permit angular adjustment of the casing for connection with the spigot.
