Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
141 words
A mixer for food and ingredients of foods comprising: an electrical motor, a housing for said motor, first and second shaft members extending downwardly from said housing, said shafts being substantially parallel and adapted to be simultaneously rotated in opposite directions, overlapping blade means including vertically extending laterally moving blades secured to the outer end portion of each of said shafts with the blades on one of the shafts rotatably interdigitating with the blades on the other shaft, vertically elongated electrical heating means with two spaced elements extending downwardly from said housing in the same direction as said shafts, each in close horizontal proximity to the blade means on a shaft for interaction therewith to provide therebetween a mixing zone supplied with heat from said heating means, and means for supplying electrical power to said heating element means and motor simultaneously.
Claim 2
Dependent Claim
141 words
A mixer for food and ingredients of foods comprising: an electrical motor, a housing for said motor, first and second shaft members extending downwardly from said housing, said shafts being substantially parallel and adapted to be simultaneously rotated in opposite directions, overlapping blade means including vertically extending laterally moving blades secured to the outer end portion of each of said shafts with the blades on one of the shafts rotatably interdigitating with the blades on the other shaft, vertically elongated electrical heating means with two spaced elements extending downwardly from said housing in the same direction as said shafts, each in close horizontal proximity to the blade means on a shaft for interaction therewith to provide therebetween a mixing zone supplied with heat from said heating means, and means for supplying electrical power to said heating element means and motor simultaneously.
Claim 3
Dependent Claim
18 words
The mixer of claim 1 in which said spaced elements vertically overlap substantially the length of said blades.
Claim 4
Dependent Claim
44 words
The mixer of claim 1 in which said spaced elements are integrally connected by a curved heater element portion bordering the major portion of the lower edge of the mixing zone of the beaters and the mixing zones between said heater elements and blades.
Claim 5
Dependent Claim
36 words
The mixer of claim 1 in which the spacing between the vertical heater elements and the paths of blades passing adjacent thereto are substantially less than the radius of the circle of movement of the blades.
