Title: Apparatus for mincing and/or beating and/or mixing edible materials such as meat, fruit and vegetables
Claims: I claim: 1. In a power-driven mixing, comminuting and blending apparatus, a hollow base, an essentially spherical container supported on and surmounting said base to have an upright diametral axis of symmetry, said container at its base being formed as a re-entrant frusto-conical protuberance symmetrical about said axis at the lower end thereof, a shaft journaled in said base for rotation coaxially with said axis and extending upwardly through said protuberance and terminating below a first plane lying intermediate the top and bottom of the container and disposed normal to said axis, a knife fixed to the upper end of said shaft contiguous with and above said protuberance, said knife including a first portion passing radially outwardly and downwardly from said axis, closely adjacent to the surface of said protuberance, and a second portion integral with said first portion and arcuately shaped to extend upwardly from the radially-outward terminus of said first portion and closely adjacent to the surface of said container, said second portion terminating in a second plane normal to said axis and intersecting the same at a point substantially below the point of intersection of said first plane with said axis, means for securing the container to the base against rotation relative to the base and means for locking the container to the base, and a motor fixed to and within said base and connected with said shaft to rotate the same, said knife also including a third portion diametrically opposite from said first and second portions and lying in and rotating in a third plane normal to said axis and substantially below said second plane, said container having an access opening in its top, symmetrical with respect to said axis, and a cover to fit the rim of said opening to close the opening, said base being constructed and arranged, when supported on a horizontal surface, to mount said axis at an angle of 5.degree. to 20.degree. to the vertical. 2. A power-driven comminuting, mixing and blending apparatus comprising a hollow base, an essentially spherical container supported on and surmounting said base to have an upright diametral axis of symmetry, said container at its base being formed as a re-entrant frusto-conical protuberance symmetrical about said axis, a shaft journaled in said base for rotation coaxially with said axis and extending upwardly through said protuberance and terminating below a first plane lying intermediate the top and bottom of the container and disposed normal to said axis, a knife fixed to the upper end of said shaft contiguous with and above said protuberance, said knife including a first portion passing radially outwardly and downwardly from said axis, closely adjacent to the surface of said protuberance, said knife also including a second portion integral with said first portion and arcuately shaped to extend upwardly from the radially-outward terminus of said first portion and closely adjacent to the surface of said container, said second portion terminating in a second plane normal to said axis and intersecting the same at a point substantially below the point of intersection of said first plane with said axis, means for securing the container to the base against rotation relative to the base and means for locking the container to the base, and a motor fixed to and within said base and connected with said shaft to rotate the same, said knife also including a third portion diametrically opposite from said first and second portions and lying in and rotating in a third plane normal to said axis and substantially below said second plane, said container having an access opening in its top, symmetrical with respect to said axis, and a cover to fit the rim of said opening to close said opening, said base being constructed and arranged, when supported on a horizontal surface, to mount said axis at an angle of 5.degree. to 20.degree. to the vertical, and wherein said means for securing the container to the base comprises two ribs standing out from the container and co-operating with two ribs standing out from the base, said two ribs standing out from the base constituted by a gently-inclined face and by a more steeply-inclined face, and said means for locking the container to the base comprise two lugs projecting from the base and two cheeks on the container, a slot for the lugs being formed in said cheeks. 3. An apparatus as claimed in claim 2, said motor having a starting contact with a push button; said cover being equipped with a cranked lug; said base being formed with a slot giving access to said push button; said cranked lug to pass through said slot; the lower portion of said cranked lug co-operating with the push button for closing and opening said starting contact. 4. An apparatus as claimed in claim 2, further comprising: a braking means for the motor; an electric circuitry actuating said braking means; an on-off switch actuating said circuitry; said circuitry comprising means to produce an instantaneous braking in the off position of said switch and when the motor is shut off by the unlocking of the cover safety interlock means controlled by the rotation of said cover to insure that the circuit remains open when the cover is not locked; said switch means being closed only after emplacement of the cover on the container.
