INSTANTANEOUS ELECTRIC WATER HEATER.
' Application lel'lannary 27, 1927. Serial No. 163,874.
This invention relates to devices for heating water as issuing `from a supply source by means of an electric coil ldisposed in the water passage.
It very frequently occurs that a moderate quantity of hot water-is required in ahouse r office and without delay, such'as would lbe necessarily encountered by the usual methods of heating; therefore the main object of the invention is `in the provision of means wherebyl such supply may become instantly availa e. v
A urther feature is to provide a heater that can be attached `and, detached from a source of water supply lin a moments time and which is immediately capable of increasing the temperature of an attenuated stream to any desired degree up to the boiling point. Another aim is to produce a heater that can be easily taken apart for cleansing and reassembled by a person of ordinary intelligence. f
\ A still further object resides in the provision of a heater entirely automatic in action and under the readyv control of anoperator.
These several advantageous features,- together with others, such as simplicity, portabilit and inexpensive construction, are accomp ished by the novel and practical con struction and combination of parts hereini after described and shown in the'accompanycurved tubular loop or bend 6.
A cylindrical casing 7 of dielectric material is formed to present an open top and closed bottom having a short axial hub bored to receive a hollow stem 8 non rotatable but adjustable lengthwise, the lower'end of the stem being threaded to engage the opening in the bend 6 and also a check-nut 9 disposed against the casing hub. i
A conical chamber 10 is formed in the casing and tight fitted therein is a hollow cone 11 reaching nearly to the solid bottom of the casing.
The cone 11 has a raised hub bored to receive the stem 8 -andis held adjustably by a check-nut 12.
The upper end of the stem is concave to receive packing 13 held. by a packing rut 14 through which passes a valve rod 15 threaded into the lstem and controlling ports 16 through its walls leading to the casing chamber 10, the rod terminating in a. needle valve 17, to close or open the passage through the stem 8.
A cover 18 is secured over the Casing to its outstanding top flange 19 and the inner top portion of the casing is annularly recessed to receive a packing ring 20 clamped by a rim 21 projecting from the hollow cone 11` by the cover to provide a liquid tight joint.
The hollow cone 11 has formed in its periphery a coarse helix 22 in which is loosel disposed the several convolutions of a higl resistance coil 23, one end of which is attached to a binding post 24 and the other end to a similar binding post 25, these binding posts having connections 26 and 27 with a snap switch 28 carried on the underside of the cover 18.
The valve rod 15 extends axially through the cover 18 and is provided with an operating handle 29 by which entrance of liquid to the chamber 10 is controlled, this chamber being in open communication with the lowermost helical groove 22, while the upper groove is open to a dispensing conduit 30 entering through the casing wall in which it is threaded.
Also fixed on the rod 15 within the space 31 of the hollow cone 11 is an adjustable collar 32 having a projection 33 adapted to throw the switch into an off and on position by corresponding movementof the handle 29.
In operation water having been turned on at the cock 5 or othensupply source, the same will enter the opening in the stem 8 and press against the needle valve 17.
Upon turning the handle 29 the rod 15 is rotated and, due to its thread, rises suiliciently to admit water past the valve 17, out of the openings 16 into the chamber 10.
Thereupon the water circulates through the grooves 22 in direct contact with the coils and passes out of the spout 30 into a receiver held to collect the issuing stream.
The handle 29 upon being further turned to permit a considerable stream to pass through the heater, acts upon the switch 28, to which current is delivered from any convenient source of electricity, heating the coil 23a-nd the water flowing through and past tle entire length of the coil in a manner'well under- Obviously upon turning the valve handle in an opposite direction, the greater volume ofY I claim as new anddesire to secure by Lettersl 1. An electric water heater comprising a cylindricall body having means to .connect with a water supply source, said body having a conical chamber and an opening leading thereto, a cover on the open end of said body,
'a hollow tapered iplug havin a raised helix on itsl periphery tting the c amber, a high resistance wire coil disposed in the grooves of said helix, a snap switch controllingfcurrent to said coil, a valve vcontrolling the passage of water through the helical grooves, said valve having a stem extending through said cover, a handle thereon, an outlet on said body in communication with the groove most 'body having a conical chamber and a solid bottom, a tapered inner shell having a helical groove fitting the chamber, a cover attached to said body to impinge on theshell, a resistance coil in the shell groove, a snap switch carried by said cover within the shell chamber, packin s for said shell, an inlet to said lchamber be ow said shell, an outlet conduit from the opposite end of the groove passing radially through the wall of said body, means for controllino' the inlet, said means extending through the cover, and means combined withsaid control means for actuating said switch.
` 3. An electric waterheater comprising inner and outer dielectric shells having a conical joint and a helical groove therebetween, a spindle. axially rotatable in said shells and provided with a valvecontrolling the passage of liquid throu h the groove, a dielectric cover, a snap swltch carried by said cover to extend into the inner shell, a resistance coil controlled by said switch, said coil being disposed in the mentioned groove, a conduit leading from the groove through the outer shell, and an arm fixed on said spindle within the inner shell to open said switch after the flow of water has been initiated and to close said switch prior to completing the valve closure. l GEORGE J. ZISCH.
