Abstract
Abstract A boiling chamber in the form of a generally cylindrical upright container, communicating at its bottom with a water tank through a restricted inlet, has a pair of vertical electrodes suspended from its top which is formed as a detachable lid. A central mounting ring on that lid has two diametrically opposite segmental cutouts engaged by respective pairs of locator rigs on the electrode shanks which terminate in transverse tabs screwed onto the lid within the ring. A nozzle assembly on the lid includes a fixed sleeve, in line with a vertical outlet aperture adjacent the outer periphery of the mounting ring, and a movable sleeve coaxially engaging the latter; the movable sleeve may carry a laterally projecting discharge tube, serving to extend the nozzle to an adjacent vessel such as a facial sauna, or may be provided with two or more ports of different diameters selectively alignable with an orifice of the fixed sleeve to establish passages of different widths for the escaping steam. The entrance end of the vertical outlet aperture is partly obstructed by a splash shield loosely seated therein to intercept droplets of water entrained by the evolving steam. Different shapes for the active lower extremities of the electrodes are described; in one embodiment, they include a generally J-shaped vertical extremity and a generally U-shaped horizontal extremity spacedly nested in the former.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
137 words
A boiling chamber for a steam generator, comprising: a generally cylindrical upright vessel provided at its bottom with an inlet for water to be boiled, said vessel having a closed top formed with an outlet for evolving steam; a mounting ring on said top within said vessel substantially centered on the cylinder axis, said ring being formed with a pair of diametrically opposite segmental cutouts open toward the bottom; a pair of electrodes depending from said top within said vessel, each of said electrodes having a generally flat stem terminating at its free end in a transverse tab secured to said top within said ring adjacent a respective cutout thereof, said stem being provided with two outwardly diverging ribs bearing upon opposite edges of the respective cutout; and nozzle means on said top communicating with said outlet.
Claim 2
Dependent Claim
137 words
A boiling chamber for a steam generator, comprising: a generally cylindrical upright vessel provided at its bottom with an inlet for water to be boiled, said vessel having a closed top formed with an outlet for evolving steam; a mounting ring on said top within said vessel substantially centered on the cylinder axis, said ring being formed with a pair of diametrically opposite segmental cutouts open toward the bottom; a pair of electrodes depending from said top within said vessel, each of said electrodes having a generally flat stem terminating at its free end in a transverse tab secured to said top within said ring adjacent a respective cutout thereof, said stem being provided with two outwardly diverging ribs bearing upon opposite edges of the respective cutout; and nozzle means on said top communicating with said outlet.
Claim 3
Dependent Claim
53 words
A boiling chamber as defined in claim 1 wherein said electrodes have lower extremities integral with their stems spacedly confronting each other above said bottom, one of said extremities comprising two portions facing respective parts of the other extremity and conductive bridge means interconnecting said portions in non-confronting relationship with said other extremity.
Claim 4
Dependent Claim
32 words
A boiling chamber as defined in claim 2 wherein said other extremity is generally J-shaped, said one of said extremities forming a horizontal U received within the J of said other extremity.
Claim 5
Dependent Claim
44 words
A boiling chamber as defined in claim 3 wherein said one of said extremities is connected with the associated stem at one of the legs of the U and bears upon the inner peripheral wall of said vessel at the bight of the U.
Claim 6
Dependent Claim
49 words
A boiling chamber as defined in claim 1 wherein said outlet is a vertical aperture in said top close to the outer periphery of said ring, said nozzle means comprising a fixed sleeve rising from said top in line with said aperture and having a lateral orifice communicating therewith.
Claim 7
Dependent Claim
34 words
A boiling chamber as defined in claim 5 wherein said nozzle means comprises a movable sleeve engaging said fixed sleeve in coaxially nested relationship and having at least one port alignable with said orifice.
Claim 8
Dependent Claim
30 words
A boiling chamber as defined in claim 6 wherein said movable sleeve detachably surrounds said fixed sleeve and is integral with a laterally extending tube provided with said discharge port.
Claim 9
Dependent Claim
46 words
A boiling chamber as defined in claim 6 wherein said movable sleeve is rotatably received in said fixed sleeve and has at least two ports of different diameters selectively alignable with said orifice in differenT rotary positions to establish passages of different widths for escaping steam.
Claim 10
Dependent Claim
25 words
A boiling chamber as defined in claim 8, further comprising toggle means urging said movable sleeve into either of two rotary positions establishing respective passages.
Claim 11
Dependent Claim
22 words
A boiling chamber as defined in claim 5 wherein said aperture is provided with a splash shield partly obstructing its entrance end.
Claim 12
Dependent Claim
33 words
A boiling chamber as defined in claim 10 wherein said splash shield comprises an upwardly tapering body mounted for substantially unrestricted vertical move ment below said entrance end and extending partly into same.
Claim 13
Dependent Claim
56 words
A boiling chamber as defined in claim 1 wherein said inlet comprises a capillary tube entering said vessel through said bottom below said electrodes, said bottom forming a widened bore around a lower end of said tube having a lateral access hole for facilitating the circulation of water from a surrounding reservoir around said lower end.
Claim 14
Dependent Claim
23 words
A boiling chamber as defined in claim 12 wherein said tube enters said vessel at an angle ranging substantially between 30* and 60*.
Claim 15
Dependent Claim
82 words
An electrode assembly for a boiling chamber of a steam generator, comprising a first electrode with a first generally flat vertical sheet-metal stem terminating in a generally J-shaped extremity in line therewith, and a second electrode with a second generally flat vertical sheet-metal stem confronting said first stem and terminating in a generally U-shaped extremity in a plane transverse to said stems, said U-shaped extremity lying on a level with the short leg of said J-shaped extremity and spacedly confronting the latter.
Claim 16
Dependent Claim
82 words
An electrode assembly for a boiling chamber of a steam generator, comprising a first electrode with a first generally flat vertical sheet-metal stem terminating in a generally J-shaped extremity in line therewith, and a second electrode with a second generally flat vertical sheet-metal stem confronting said first stem and terminating in a generally U-shaped extremity in a plane transverse to said stems, said U-shaped extremity lying on a level with the short leg of said J-shaped extremity and spacedly confronting the latter.
Claim 17
