Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
179 words
A liquefier having an upwardly open jar defining a central space that is open throughout its length and bounded by circularly spaced radially recessed side wall portions disposed above a mounting base portion to define contiguous vortexing portions; bottom closure means releasably secured to said mounting base portion and including two pairs of radially extending cutter blades; one pair extending upwardly and outwardly at approximately a 45° angle rotatably supported in said central space, and the other pair extending downward-and-out with their tips at approximately the lower ends of said recessed side wall portions, said blades being pitched for impulsion of liquid material in the jar in a downward direction when rotated; means for journaling the blades for rotation about a vertical axis including a pillar supporting the blades above the lower ends of said recessed side walls and having a plurality of circumferentially spaced recesses of varying radial depths normal to said axis and opening radially outwardly, said recesses being of a radial depth less at their circumferentially adjacent ends than at their central portions intermediate their ends.
Claim 2
Dependent Claim
179 words
A liquefier having an upwardly open jar defining a central space that is open throughout its length and bounded by circularly spaced radially recessed side wall portions disposed above a mounting base portion to define contiguous vortexing portions; bottom closure means releasably secured to said mounting base portion and including two pairs of radially extending cutter blades; one pair extending upwardly and outwardly at approximately a 45° angle rotatably supported in said central space, and the other pair extending downward-and-out with their tips at approximately the lower ends of said recessed side wall portions, said blades being pitched for impulsion of liquid material in the jar in a downward direction when rotated; means for journaling the blades for rotation about a vertical axis including a pillar supporting the blades above the lower ends of said recessed side walls and having a plurality of circumferentially spaced recesses of varying radial depths normal to said axis and opening radially outwardly, said recesses being of a radial depth less at their circumferentially adjacent ends than at their central portions intermediate their ends.
Claim 3
Dependent Claim
26 words
The liquefier defined in claim 1 in which said recessed side walls are four in number while said spaced outwardly opening recesses are three in number.
Claim 4
Dependent Claim
19 words
The liquefier defined in claim 1 in which said recesses define substantially cylindrical surfaces with their axes disposed horizontally.
Claim 5
Dependent Claim
75 words
The liquefier defined in claim 1 in which ingredients impelled downwardly and inwardly engage the upper upright radially directed portions of the surfaces of the recesses of varying radial depth normal to the axis of rotation and are progressively redirected radially outward for horizontal discharge into the lower ends of said recessed side walls in a radial direction across a narrow circular clearance between said pillar and mounting base portion coaxial with said central space.
Claim 6
Dependent Claim
39 words
A liquefier defined in claim 1 in which said wall has a conical shape and each recess comprises a cavity in the wall defining a surface of revolution having an axially directed horizontal portion transversely intersecting said conical wall.
Claim 7
Dependent Claim
26 words
The liquefier defined in claim 1 in which said recessed side walls are four in number while said spaced outwardly opening recesses are three in number.
Claim 8
Dependent Claim
158 words
A liquefier having a rotating prime mover and comprising: an elongated container jar disposed upright having fluted side walls cross-sectionally defining a cloverleaf shape with a reduced circular shoulder adjacent the lower ends of the flutes; a bottom element closing the lower end below said shoulder and having a central conical portion extending above said shoulder journaling a shaft driven by said prime mover; cutter means carried by said shaft having a lower cutting edge portion substantially following the contour of said conical portion and terminating in close proximity to said shoulder for driving liquid against the conical surface in one area; said conical portion having a plurality of circumferentially spaced recess means in said surface area of a depth varying circumferentially in a plane normal to the axis of the conical portion for redirecting liquid towards said shoulder; and said cutter means having another cutting edge portion for driving liquid from said recess means to said shoulder.
Claim 9
Dependent Claim
158 words
A liquefier having a rotating prime mover and comprising: an elongated container jar disposed upright having fluted side walls cross-sectionally defining a cloverleaf shape with a reduced circular shoulder adjacent the lower ends of the flutes; a bottom element closing the lower end below said shoulder and having a central conical portion extending above said shoulder journaling a shaft driven by said prime mover; cutter means carried by said shaft having a lower cutting edge portion substantially following the contour of said conical portion and terminating in close proximity to said shoulder for driving liquid against the conical surface in one area; said conical portion having a plurality of circumferentially spaced recess means in said surface area of a depth varying circumferentially in a plane normal to the axis of the conical portion for redirecting liquid towards said shoulder; and said cutter means having another cutting edge portion for driving liquid from said recess means to said shoulder.
Claim 10
Dependent Claim
51 words
The combination of claim 7 in which said cutter means includes upwardly inclined cutters with leading cutting edges on upwardly diverging blade portions pitched to cavitate the area above them by positive impulsion of liquid in the container in downwardly diverging directions to force the liquid up the fluted side wall.
Claim 11
Dependent Claim
65 words
A liquefier comprising: a container for mixtures with solid ingredients therein; a conical wall member radially defining a plurality of radially open recesses of circumferentially varying depth in a direction perpendicular to its conical axis; a drive shaft journaled in said wall proximate said recesses including a cutting edge followed by a body portion pitched to drive liquid and solids circumferentially through said radial recesses.
Claim 12
Dependent Claim
65 words
A liquefier comprising: a container for mixtures with solid ingredients therein; a conical wall member radially defining a plurality of radially open recesses of circumferentially varying depth in a direction perpendicular to its conical axis; a drive shaft journaled in said wall proximate said recesses including a cutting edge followed by a body portion pitched to drive liquid and solids circumferentially through said radial recesses.
Claim 13
Dependent Claim
164 words
A liquefier having an upwardly open jar defining a central space open throughout its length bounded by circularly spaced radially recessed side walls extending above a mounting base portion and defining contiguous vortexing sections; bottom closure means releasably secured to said mounting base portions rotatably supporting a cutter assembly supported on said mounting base portion and including two pairs of blades, one pair extending upwardly and outwardly at approximately a 45° angle supported in said central space and the other pair extending downward-and-out with their tips at approximately the lower ends of said recessed side walls; said blades being pitched for downward movement of liquid material in the jar when rotated; means for journaling the blades from rotation about a vertical axis including a pillar supporting the blades above the lower ends of said recessed side walls and having a plurality of circumferentially spaced recesses opening radially outwardly, said recesses being of a radial depth less at their circumferential ends than intermediate their ends.
