Abstract
Abstract A comestible freezer has a freezing barrel with a cold wall, an input end and an output end and a feeder therewithin having a ribbon auger flight helix and a stationary blending bar within the helix. A portion of the ribbon auger flight helix has an outward twist or skew diverging from a radial plane through the axis of the helix and outwardly toward the barrel wall whereby to exert a component of thrust on the comestible toward the cold wall. A portion of the ribbon also has an inward twist or skew diverging from the radial plane and inwardly toward the blending bar whereby to exert a component of thrust on the comestible toward the bar.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
125 words
In a comestible freezer having a freezing barrel with a cold wall, said barrel having an input end and an output end and a feeder therewithin having an auger ribbon flight helix, the improvement in which the ribbon of said flight helix has an outward skew diverging from a radial plane through the axis of the helix and outwardly toward the barrel wall whereby to exert a component of thrust on the comestible toward said wall and in which said freezer has a blending bar within said helix, the ribbon of said flight helix having a portion with an inward skew diverging from said radial plane and inwardly toward said blending bar whereby to exert a component of thrust on the comestible toward said bar.
Claim 2
Dependent Claim
125 words
In a comestible freezer having a freezing barrel with a cold wall, said barrel having an input end and an output end and a feeder therewithin having an auger ribbon flight helix, the improvement in which the ribbon of said flight helix has an outward skew diverging from a radial plane through the axis of the helix and outwardly toward the barrel wall whereby to exert a component of thrust on the comestible toward said wall and in which said freezer has a blending bar within said helix, the ribbon of said flight helix having a portion with an inward skew diverging from said radial plane and inwardly toward said blending bar whereby to exert a component of thrust on the comestible toward said bar.
Claim 3
Dependent Claim
87 words
The invention of claim 1 in which said outward skew extends along a portion of said helix from the input end of the barrel toward its output end and said inward skew extends along a portion of said helix from the output end of the barrel toward its input end whereby comestible near said input end is subject to a component of thrust toward the cold wall of the barrel and comestible near said output end is subject to a component of thrust toward said blending bar.
Claim 4
Dependent Claim
19 words
The invention of claim 2 in which said inward skew has a greater axial extent than said outward skew.
Claim 5
Dependent Claim
34 words
The invention of claim 2 in which said outward skew extends along approximately one-third the axial length of the helix and the inward skew extends along approximately two-thirds the axial length of the helix.
Claim 6
Dependent Claim
118 words
In a comestible freezer having a freezing barrel with an input end and an output end and a feeder therewithin having an auger ribbon flight helix and a blending bar within said helix, the improvement in which the ribbon of said flight helix has an inward skew diverging from a radial plane through the axis of the helix and inwardly toward the blending bar whereby to exert a component of thrust on the comestible toward said bar and in which said barrel has a cold wall, the ribbon of said flight helix having an outward skew diverging from said radial plane toward the barrel wall whereby to exert a component of thrust on the comestible toward said wall.
Claim 7
Dependent Claim
118 words
In a comestible freezer having a freezing barrel with an input end and an output end and a feeder therewithin having an auger ribbon flight helix and a blending bar within said helix, the improvement in which the ribbon of said flight helix has an inward skew diverging from a radial plane through the axis of the helix and inwardly toward the blending bar whereby to exert a component of thrust on the comestible toward said bar and in which said barrel has a cold wall, the ribbon of said flight helix having an outward skew diverging from said radial plane toward the barrel wall whereby to exert a component of thrust on the comestible toward said wall.
Claim 8
Dependent Claim
87 words
The invention of claim 5 in which said outward skew extends along a portion of said helix from the input end of the barrel toward its output end and said inward skew extends along a portion of said helix from the output end of the barrel toward its input end whereby comestible near said input end is subject to a component of thrust toward the cold wall of the barrel and comestible near said output end is subject to a component of thrust toward said blending bar.
Claim 9
Dependent Claim
102 words
In a comestible freezer having a freezing barrel and a feeder therewithin having an auger ribbon flight helix, the improvement in which the ribbon of the flight helix is skewed with respect to a radial plane through the axis of the helix whereby to exert a radial component of thrust on the comestible and wherein approximately 1/3 of the length of the ribbon is skewed outwardly at an angle of 2° to 12° with respect to a radial plane and the remaining portion of the ribbon is skewed inwardly at an angle of 14° to 33° with respect to a radial plane.
Claim 10
Dependent Claim
102 words
In a comestible freezer having a freezing barrel and a feeder therewithin having an auger ribbon flight helix, the improvement in which the ribbon of the flight helix is skewed with respect to a radial plane through the axis of the helix whereby to exert a radial component of thrust on the comestible and wherein approximately 1/3 of the length of the ribbon is skewed outwardly at an angle of 2° to 12° with respect to a radial plane and the remaining portion of the ribbon is skewed inwardly at an angle of 14° to 33° with respect to a radial plane.
Claim 11
Dependent Claim
33 words
The invention of claim 7 in which the freezer has a fixed blending bar within said helix, and said inwardly skewed portion exerts a component of thrust on said comestible toward said bar.
Claim 12
Dependent Claim
147 words
In a comestible freezer having a freezing barrel with an input end and an output end and a feeder therewithin having an auger ribbon flight helix, the improvement in which the ribbon of the flight helix is skewed with respect to a radial plane through the axis of the helix whereby to exert a radial component of thrust on the comestible and in which the freezer has a fixed blending bar within said helix, said flight ribbon being skewed inwardly toward said blending bar for a portion of its length adjacent the output end whereby to exert a component of thrust on said comestible toward said bar, and in which the freezer has a cold wall, a portion of the flight ribbon adjacent the input end being skewed outwardly toward said cold wall whereby to exert a component of thrust on said comestible toward said cold wall.
Claim 13
Dependent Claim
147 words
In a comestible freezer having a freezing barrel with an input end and an output end and a feeder therewithin having an auger ribbon flight helix, the improvement in which the ribbon of the flight helix is skewed with respect to a radial plane through the axis of the helix whereby to exert a radial component of thrust on the comestible and in which the freezer has a fixed blending bar within said helix, said flight ribbon being skewed inwardly toward said blending bar for a portion of its length adjacent the output end whereby to exert a component of thrust on said comestible toward said bar, and in which the freezer has a cold wall, a portion of the flight ribbon adjacent the input end being skewed outwardly toward said cold wall whereby to exert a component of thrust on said comestible toward said cold wall.
