Abstract
Abstract A portable hand-held steam generating apparatus includes a permanently sealed housing in which a quantity of water is disposed, the housing being shaped such that it contains the quantity of water in any portion taken about and through the center of the housing. Steam is produced by heating water in the lower portion of the housing using a pair of spaced, heatconducting electrodes that are water-activated. From the center of the housing, a nozzle, having greater cross-sectional area at its intake end than at its discharge end in order to increase steam pressure, directs steam toward a surface to be treated. A handle for the apparatus is slidable from a position within the housing to an extended position where it may be used to control the direction of the issuing steam.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
165 words
Portable hand-held steam producing apparatus, comprising: a. a housing for containing a quantity of water in the lower portion thereof; b. heating means contained within said housing for heating said quantity of water to generate steam; and c. nozzle means having an intake end positioned within said housing and a discharge end for directing said steam from said housing against a surface to be treated with said steam; wherein the improvement comprises: d. means for supporting said nozzle means with said intake end of said nozzle means disposed near the geometric central region of said housing, said housing having a substantially equal capacity for containing water in all directions taken about said geometric central region such that said housing provides a sufficient volume in all directions taken about said intake end of said nozzle means to accommodate said quantity of water such that said water will not exit said housing to said discharge end of said nozzle means upon inversion or tilting of said apparatus.
Claim 2
Dependent Claim
165 words
Portable hand-held steam producing apparatus, comprising: a. a housing for containing a quantity of water in the lower portion thereof; b. heating means contained within said housing for heating said quantity of water to generate steam; and c. nozzle means having an intake end positioned within said housing and a discharge end for directing said steam from said housing against a surface to be treated with said steam; wherein the improvement comprises: d. means for supporting said nozzle means with said intake end of said nozzle means disposed near the geometric central region of said housing, said housing having a substantially equal capacity for containing water in all directions taken about said geometric central region such that said housing provides a sufficient volume in all directions taken about said intake end of said nozzle means to accommodate said quantity of water such that said water will not exit said housing to said discharge end of said nozzle means upon inversion or tilting of said apparatus.
Claim 3
Dependent Claim
28 words
Apparatus according to claim 1, wherein said heating means comprises a pair of spaced heat-conducting electrodes directed into said water contained in the lower portion of said housing.
Claim 4
Dependent Claim
75 words
a conduit leading to the nozzle, said conduit having an intake end; wherein the improvement comprises: d. means for supporting the intake end of said conduit near the geometric center of the housing such that said housing provides, in any orientation of the steam-producing apparatus, a volume below said geometric center of the housing which is greater than said predetermined volume of water, so that water cannot flow out of the housing through said conduit.
Claim 5
Dependent Claim
75 words
a conduit leading to the nozzle, said conduit having an intake end; wherein the improvement comprises: d. means for supporting the intake end of said conduit near the geometric center of the housing such that said housing provides, in any orientation of the steam-producing apparatus, a volume below said geometric center of the housing which is greater than said predetermined volume of water, so that water cannot flow out of the housing through said conduit.
Claim 6
Dependent Claim
35 words
Apparatus as in claim 1 wherein said heating means comprises a pair of electrodes immersible in said quantity of water contained in said housing, said water serving as electrolyte for conducting current between said electrodes.
Claim 7
Dependent Claim
38 words
Portable hand-held steam producing apparatus, comprising: a. a housing for containing a predetermined volume of water to be converted to steam; b. heating means in the lower part of the housing; c. outlet means for the housing including:
Claim 8
Dependent Claim
38 words
Portable hand-held steam producing apparatus, comprising: a. a housing for containing a predetermined volume of water to be converted to steam; b. heating means in the lower part of the housing; c. outlet means for the housing including:
Claim 9
Dependent Claim
37 words
Portable hand-held steam producing apparatus according to claim 4, including a. a container for measuring said predetermined volume; b. means for attaching said container to said steam producing apparatus; and c. a removable stopper for said housing.
Claim 10
Dependent Claim
44 words
Portable hand-held steam producing apparatus according to claim 5, including: a. a handle for said apparatus attached to the housing and having a projecting leg; b. said container, when empty, engages said projecting leg, said leg serving as a part of said attaching means.
