Abstract
Abstract This invention provides for a portable ice cube maker, in which ice cubes are made in ice pockets provided in an insulated container having a cover and in which the ice pockets are accessable upon removing the cover, yet providing for an enclosed container space into which the ice cube pockets depend and a cover extendable over the top of the container and removable therefrom to provide access to the ice cube pockets for the addition of water or the removing of the ice cubes. An ice cube pulling extractor is provided having parrallel portions dependable into the bottoms of the ice cube pockets and transverse pull portions available at the opposite ends of the containers for effecting the pulling of the extractor and the ice cubes from the container. Refrigerant is admitted to the space within the container from a refrigerant bottle having a depressable shank extending from the neck of the bottle and the neck of the bottle extending through an opening either through the bottom of the container or through a cover thereof. A push rod is used in one form of the invention to depress the bottle shank and in the other form of the invention a shank is depressed by engaging the same with a ball valve device lying within the container space. Appropriate valves are provided for excess pressure and to prevent the admission of air into the casing and to effect the draining of the bottom of the casing.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
255 words
A portable ice cube maker comprising: an ice cube making container having a top and bottom and having ice-forming compartments comprising ice-pockets depending from the top of the container into an internal space thereof, said container having an opening in its wall for receiving a neck of a pressurized bottle containing a valve shank; means associated with the opening for effecting the depression of the valve shank to admit refrigerant from the pressurized container into the internal space of the ice making container; said container having a cover adapted to be extended over these pockets and removable for the insertion of water into the ice pockets and the removal of the ice cubes therefrom, said ice-forming pockets having opposing ribs to provide weakened portions in the ice extracted from the pockets, said ice cube container having an inner liner with a top and bottom, said inner liner being closed at the top and said ice pockets being depressed from the top of the inner liner and into the container space, said pockets running longitudinally of the container and parallel to one another and spaced from each other and from the sides of the container to provide space into which the refrigerant gas may expand for full contact with the walls of the ice pocket; an ice extractor extendable into the ice pockets and running along the bottoms thereof, and said extractor being cut to be accommodated to the vertically extending ribs within the pockets so as to lie flush upon the bottoms of the pockets.

Claim 3
Dependent Claim
62 words
A portable ice cube maker, as defined in claim 1, and the top of said container having depressions adjacent to the opposite ends of the ice pockets, said extractor having handle pull portions overlying the depressions whereby fingers can be extended into the depressions and under the pull portions to grasp the extractor for effectively pulling the same from the ice pockets.
Claim 4
Dependent Claim
50 words
A portable ice cube maker, as defined in claim 1, and said container having a bottom wall, the valve seat extending through the bottom wall and a depressable valve cooperating with the valve seat to open the space within the container to drain the bottom of the container from liquid.
Claim 5
Dependent Claim
76 words
A portable ice cube maker, as defined in claim 3, and underslung support member extending across the bottom of the container and upwardly along the sides thereof, a handle pivotally connected to the upper ends of the underslung support at the sides thereof and serving when extended over the container to permit the carrying of the container by the handle, said valve seat extending through said underslung support with the drain valve being excessable there through.
Claim 6
Dependent Claim
60 words
A portable ice cube maker, as defined in claim 1, and a ball valve carried upon the container and said cover having an opening through which the neck of the refrigerant bottle may be extended for engagement with the ball valve to depress the valve shank of the bottle and inject refrigerant gas into the container below said inner liner.
Claim 7
Dependent Claim
96 words
A portable ice cube maker, as defined in claim 1, said refrigerant bottle being secured to the bottom of the ice making container, a push rod extending from the refrigerant container and carried on its valve shank and extending upwardly through the container and through the cover and accessible from the top thereof to be depressed, a bottom tray and said container being recessed to receive the bottom of the container into the tray, and handle carrying means connected to the tray being extendable over the cover to permit the carrying of the ice cube maker.
