Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
152 words
Refrigerator mixer apparatus comprising a refrigerator compartment normally maintained at least at a freezing temperature or therebelow, a motor secured to the exterior of said refrigerator compartment, first mounting means within said compartment, a mixing chamber detachably connected to said first mounting means, second mounting means connected to a wall of said compartment near a corner therein, and driven means connected for rotation at one end to the drive shaft of said motor and selectively detachably connected at the other end to said second mounting means and said mixing chamber for activating said mixing chamber allowing said mixing chamber of any desired size to mix the food in said compartment, said mixing chamber to be completely removed from said compartment at the expiration of the mixing operation, and said driven means to be disengaged from said mixing chamber and secured to said second mounting means at the expiration of the mixing operation.
Claim 2
Dependent Claim
152 words
Refrigerator mixer apparatus comprising a refrigerator compartment normally maintained at least at a freezing temperature or therebelow, a motor secured to the exterior of said refrigerator compartment, first mounting means within said compartment, a mixing chamber detachably connected to said first mounting means, second mounting means connected to a wall of said compartment near a corner therein, and driven means connected for rotation at one end to the drive shaft of said motor and selectively detachably connected at the other end to said second mounting means and said mixing chamber for activating said mixing chamber allowing said mixing chamber of any desired size to mix the food in said compartment, said mixing chamber to be completely removed from said compartment at the expiration of the mixing operation, and said driven means to be disengaged from said mixing chamber and secured to said second mounting means at the expiration of the mixing operation.
Claim 3
Dependent Claim
47 words
The apparatus of claim 1 wherein said first mounting means includes a projection extending upward from the bottom wall of said compartment, said mixing chamber having a hole in the center of a bottom surface thereof removably mating with said projection for stabilization of said mixing chamber.
Claim 4
Dependent Claim
158 words
The apparatus of claim 1, wherein said mixing chamber includes a chamber, a rotatably mounted blade vertically positioned within said chamber and having dimensions slightly less than those of the vertical cross section of said mixing chamber taken along the longitudinal axis thereof, a shaft extending from the top of said blade and protruding from the top of said chamber aNd detachably connected to said driven means for rotation, the cross section of said blade having an undulated shape with wavelike crests and valleys, said blade having a vertical column of holes along each crest and a baffle angularly extending over each of said holes causing the food being mixed to be concentrated and present the greatest pressure at specific areas along said rotating blade and to be directed in a stream from one side of a midportion of said blade to the other for integrated agitation and mixing of food on both sides of said rotating blade.
