ELECTRIC WATER-HEATER Specification of Letters-Patent.

-implication filed May 19, |1915'. Serial No. 29,196.

'0 all whomz't'm'ay concern.'

- Bel it' known that 1,'LOU1s C. HnNiuKsnN,

a citizen of the' United States, residing at Port-land, in the'county of Multnomah. and

- State ofv Oregon, have invented new and .useful Improvements in Electric lVater- Heaters', of which the-following is a specification. i n 'l L This inveiit'ioh relates to hot'water heaters andl `espet'zially to -lheaters of the instantaneous. typ'e.v I The main' object of this inventionv is to provide'a heater which may be connected into" the piping-'systei'nof a house and which will Abe automatically operated by the flowl of waterv through the system. .4

` #Another ob'ect is to 4provide a heater having an electricalresistance coil. inclosed in a -container which is in' communication v.with the house system and an electrical contact niaking'ineans foi-closing the electrical circuit' which will i be ,operatedv by 'the iiow ot .water so,that,if any valve in the'system is openeclfor the dischargeof water, the heater will'be.thrown-into operation. l

lt is a :further obiect to provide an' electrical heaterlwhich comprises ya 'container embodying theheating element a'nda valve.

.which will close and preventthe circulation of heated water contained 4tliereinlack into,

the feeder system when water is not being used in the house system.

mamier to present a, large `surface kto the "watein lattain ,these objects by means of the. em-

bodiment of my "invention: disclosed in the 'accoinpanyingdrawing, in which: 4.

heating element. member provide a contact ot' the circuit closy A still fui-ther object is to provide a heater. with' a resistance coil'which 1s wound in av nectedinto thewalls of lthe tubular member. and insulated' therefrom. The terminal 8 -comprises a threaded stem4 9 adapted 'to re-y ceive a thumb nutj10 and a half round head ..11 -provided with a grooveV for a screw driver. NA,- bushing 12 insulates the terminal ppst 8v froin'the'tubular member G. An angle member .'13 is disposed upon the post 8 and Connected-.to the angle member 13 -is one end of a heating element which comprises units as illustrated in Fig. (Storming a stai' skeleton expanded presenting a large vsurface to the water which will' passthiough the tube T. A terminal postl is disposed near the flower end of i tubular member G and coi-nprises a threaded stemvhai-'ing a' head .grooved to receive a screw driver. A'ineniber 16 is mounted upon the stem of .the post 15 and between the head of the post and'a bushing lfwhich insulates the post from the tubular membei' (5. y

, The nieniber ,'16 provides onecontact .for'a circuit closing device. lConnected Vto the e Patented Dee. A251915.

"laterally .of the plane of the star, thereby i lower endv ot' heating element 1i is an angle memberilo .which is provided with upturned portions 1l)A and 520i The upturned portion '#20 provides. the point of 1connection to the The legs ofthe angle A tube 25* isv secured in the nipple :23 and the lower end thereot` isattached to .the piping for the house. A valve 26 which has an .insulated head Q7 and alstem QS is disposed' within the'tubular member 6' with its stem extending into the tube 25. Disk 21 is secured to insulation :'27 so that 'the disk moves' with stem 2S.' Stem 2S is provided with grooves 20 which have a substantially right angle shoulder at the upper portion and form surfaces against which the water impinges` in its-How into the heater. A cap .30 is secured to theupper end of the tubular member 6,' awasher 31 being. interposed between the cap and tubular member to pro# lio ride -a non-leak joint. rlhe cap E@ has a threaded nipple 32 into Which pipin to the hot Water is attachee 85:3 indicates an ordinary faucet, Terminal posts S and are adapted to he connected to any source of electrical energy.

vReferring particularly to the construction y shown in Fizl with faucet 33 closed, no

Water is owing through the system, valve 26 Will loe seated and the electrical circuit is open by reason of the

breakbetween contact points

16 and 18. The valve 26 pre? iients Water in the heater from circulating back into the system, beyond the'heater. Upon opening the faucet 33 the pressure offwater lifts valve 26 and the` inlowing Waterimpinging against the shoulders forming recesses 29 and the head 2'? fwill main- -tain the Valve in its upward yposition in which 1t. forces disk 21 against

terminals

16 and 18, thereby closing the electrical circuit. The flow ofelectricity along the heating element le'causes heating of the same and the Water flewing through the heater comes into intimate contact with the several units so that 1t isthoroughly heated. W hen faucet 33 is closed valve 26 drops due to -its to one pole of a source of electrical energy, acontact member connected to the other end of said heating element, a terminalldisposed adjacent saidiirst named contact member adapted to be connected to said source of electrical energy, areciprocable contact member disposed to close the circuit, and a valve including a: sternv With channels thereon ladapted to be acted upon by the impact of flowing liquid, and disposed to Vactuate said reciprocable contact member.

-pact surfaces for the Water.

An electrical Water heater, comprising a liquid. container, a heating element disposed in said container, means to supply electrical energy'v to said heating element, one terminal thereof connected to said heating element, a tubular inlet conduit cornn nected to said container, a stem, a reciprocable dish of electrical conducting material mounted upon vsaid stem and disposed for engagement With ,a terminal of the heating element and the other terminal of the source of electrical' energy, said stem being disposed in'said tubular inlet conduit and provided with impact surfaces for lthe Water.

In Witness that I claim the foregoing I have hereunto subscribed my name this th day of April, 1915. f p
