Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
154 words
An electric steam iron having independent steam-generating systems comprising: a. a sole plate having a U-shaped heating element embedded therein, a first steam-generating chamber adapted to receive water from a tank disposed in the iron, a deep U-shaped channel in the sole plate on the outside of the U-shaped heater and steam ports extending from the U-shaped channel to the undersurface of the sole plate, passageways disposed along the top of the U-shaped element connecting the first steamgenerating chamber and the U-shaped channel adjacent the heel of the iron, and a second steam-generating chamber in the sole plate adapted to also receive water from a tank disposed in the iron; b. cover plate means engaging the top surface of the sole plate to close off said chambers, passageway and channel, the cover plate means having conduit means adapted to connect the second steam-generating chamber and the U-shaped channel at the toe of the iron.
Claim 2
Dependent Claim
154 words
An electric steam iron having independent steam-generating systems comprising: a. a sole plate having a U-shaped heating element embedded therein, a first steam-generating chamber adapted to receive water from a tank disposed in the iron, a deep U-shaped channel in the sole plate on the outside of the U-shaped heater and steam ports extending from the U-shaped channel to the undersurface of the sole plate, passageways disposed along the top of the U-shaped element connecting the first steamgenerating chamber and the U-shaped channel adjacent the heel of the iron, and a second steam-generating chamber in the sole plate adapted to also receive water from a tank disposed in the iron; b. cover plate means engaging the top surface of the sole plate to close off said chambers, passageway and channel, the cover plate means having conduit means adapted to connect the second steam-generating chamber and the U-shaped channel at the toe of the iron.
Claim 3
Dependent Claim
53 words
An electric steam iron as claimed in claim 1 wherein the passage comprises an annular recess extending upward in the cover plate means sealed by an annular plate, the annular plate having ports disposed one above and in communication with the second steam-generating chamber and one above the toe of the U-shaped channel.
Claim 4
Dependent Claim
61 words
An electric steam iron as claimed in claim 1 wherein substantially horizontal apertures are formed in the heel of the sole plate at the distal ends of the deep U-shaped channel, and removable plug means are usually installed blocking the apertures respectively whereby the plug means may be removed to permit exit of steam from the passage to clean the channel.
Claim 5
Dependent Claim
44 words
An electric steam iron as claimed in claim 3 wherein the plugs are held respectively over the apertures by a pair of spring cantilevered arms, the arms being both secured to the rear of the iron adjacent the centerline thereof and extending outward therefrom.
Claim 6
Dependent Claim
21 words
An electric steam iron as claimed in claim 4 wherein the distal ends of the arms are secured to the plugs.
