Abstract

Abstract A safety device for a steam vaporizer having a liquid reservoir base with a removable top. A pair of electrodes depend from the top into the reservoir base for heating a liquid. To remove the top from the base, spaced terminals provided in a terminal block must be disengaged from shorting conductors on the base reservoir, thereby opening the power circuit to the electrodes, In one embodiment, the terminal block is an integral part of the top. In another embodiment, the block is secured to the top by connector cord of such length that the block terminals must be disengaged from the shorting conductors in order to remove the top with its dependent electrodes from the base.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 250 words
An electrical vaporizer comprising, in combination, a liquid reservoir base, a removable top mounted on said base, electricalheating means depending from said top into said reservoir base, a pair of mutually insulated electrically conductive members mounted on said base, an insulator block secured to said top by means comprising conductive wires and having opening means for receiving said conductive members, two pairs of aligned spaced terminals positioned in said insulator block and accessible through said opening means, each one of said terminals being electrically insulated from the others of said terminals, said conducting members establishing paths of electrical communication between aligned ones of said pairs of terminals when said insulator block is positioned on said base with said conductive members received within said opening means and wherein the electrical communication is broken when said top is removed from said base and said insulator block is removed from said conductive members, a power cord having one end in electrical communication with one terminal of each pair of aligned terminals and its other end adapted for connection to a source of electrical power, said means comprising conductive wires having one end in electrical communication with the other terminal of each pair of aligned terminals and its other end in electrical communication with said heating means, said insulator block being secured to said top by means comprising conducting wires at a distance such that said insulator block must be removed from said conductive members in order to remove said top from said base.
Claim 2
Dependent Claim 250 words
An electrical vaporizer comprising, in combination, a liquid reservoir base, a removable top mounted on said base, electricalheating means depending from said top into said reservoir base, a pair of mutually insulated electrically conductive members mounted on said base, an insulator block secured to said top by means comprising conductive wires and having opening means for receiving said conductive members, two pairs of aligned spaced terminals positioned in said insulator block and accessible through said opening means, each one of said terminals being electrically insulated from the others of said terminals, said conducting members establishing paths of electrical communication between aligned ones of said pairs of terminals when said insulator block is positioned on said base with said conductive members received within said opening means and wherein the electrical communication is broken when said top is removed from said base and said insulator block is removed from said conductive members, a power cord having one end in electrical communication with one terminal of each pair of aligned terminals and its other end adapted for connection to a source of electrical power, said means comprising conductive wires having one end in electrical communication with the other terminal of each pair of aligned terminals and its other end in electrical communication with said heating means, said insulator block being secured to said top by means comprising conducting wires at a distance such that said insulator block must be removed from said conductive members in order to remove said top from said base.
Claim 3
Dependent Claim 18 words
An electrical vaporizer, according to claim 1, wherein said conductive members comprise a pair of parallel metallic rods.
Claim 4
Dependent Claim 35 words
