Abstract
Abstract An electric steam generator comprises a cylindrical receptacle, containing heating means having a spaced double walled jacket receiving a wick therebetween and open at the top to admit liquid to the wick for vaporization. The heating means comprises a heating wire on the inside of the jacket and is mounted on a float functioning as a piston in the receptacle. An electric terminal ring is fixed on the upper part of the receptacle and a conductor pin is connected to one end of the heating wire and extends upwardly through said terminal ring in sliding contact with the inner wall of said ring to feed current to said heating wire, while it leaves the terminal ring to brake the current when the liquid has vaporized and the float reaches the bottom of the receptacle.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
106 words
Electric steam generator consisting of a receptacle having a steam jet opening at the top and containing a liquid to be vaporized, electric water heating means mounted on a float in said receptacle and susceptible of floating on said liquid, electric current supply means disposed in said receptacle and having one terminal connected to said electric water heating means, and a conductor connected to said electric heating means and disposed in sliding contact with the other terminal of said current supply means, said conductor breaking contact with said other terminal as said electric heating means descends on said float in said receptacle beyond a predetermined level.
Claim 2
Dependent Claim
106 words
Electric steam generator consisting of a receptacle having a steam jet opening at the top and containing a liquid to be vaporized, electric water heating means mounted on a float in said receptacle and susceptible of floating on said liquid, electric current supply means disposed in said receptacle and having one terminal connected to said electric water heating means, and a conductor connected to said electric heating means and disposed in sliding contact with the other terminal of said current supply means, said conductor breaking contact with said other terminal as said electric heating means descends on said float in said receptacle beyond a predetermined level.
Claim 3
Dependent Claim
106 words
Electric steam generator consisting of a receptacle having a steam jet opening at the top and containing a liquid to be vaporized, electric water heating means mounted on a float in said receptacle and susceptible of floating on said liquid, electric current supply means disposed in said receptacle and having one terminal connected to said electric water heating means, and a conductor connected to said electric heating means and disposed in sliding contact with the other terminal of said current supply means, said conductor breaking contact with said other terminal as said electric heating means descends on said float in said receptacle beyond a predetermined level.
Claim 4
Dependent Claim
106 words
Electric steam generator consisting of a receptacle having a steam jet opening at the top and containing a liquid to be vaporized, electric water heating means mounted on a float in said receptacle and susceptible of floating on said liquid, electric current supply means disposed in said receptacle and having one terminal connected to said electric water heating means, and a conductor connected to said electric heating means and disposed in sliding contact with the other terminal of said current supply means, said conductor breaking contact with said other terminal as said electric heating means descends on said float in said receptacle beyond a predetermined level.
Claim 5
Dependent Claim
54 words
Electric steam generator according to claim 1, wherein said electric water heating means comprises an elongate tubular heating element containing an electric heating wire and having spaced double walls containing a wick, the outer wall of said tubular heating element having a calibrated opening at its lower extremity to admit liquid to be vaporized.
Claim 6
Dependent Claim
53 words
Electric steam generator according to claim 2, wherein the float carrying said electric heating means functions as a piston in said receptacle and that the tubular heating element widens at the top into a flange terminating in an elastic band which assures a very flexible joint with the inner wall of the receptacle.
