Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
136 words
An apparatus for washing cereals comprising in combination, a hopper of reduced size at the lower part thereof, and having an opening at its bottom, a cereal washing tank positioned under the opening and larger than the opening, the said opening being no lower than that of a cover on the tank, which cover has an opening therein, a hollow water supply tube projecting into the cereal washing tank, and a hollow rotor on said tube and connecting to said tube, the rotor having an upper vertically extending flange plate with a notch at the upper edge thereof and having a jet hole in the rotor for water discharge to rotate the rotor, and the top of the rotor extending into the opening in the lower part of the hopper to reduce the discharge area thereof.
Claim 2
Independent Claim
136 words
An apparatus for washing cereals comprising in combination, a hopper of reduced size at the lower part thereof, and having an opening at its bottom, a cereal washing tank positioned under the opening and larger than the opening, the said opening being no lower than that of a cover on the tank, which cover has an opening therein, a hollow water supply tube projecting into the cereal washing tank, and a hollow rotor on said tube and connecting to said tube, the rotor having an upper vertically extending flange plate with a notch at the upper edge thereof and having a jet hole in the rotor for water discharge to rotate the rotor, and the top of the rotor extending into the opening in the lower part of the hopper to reduce the discharge area thereof.
Claim 3
Dependent Claim
78 words
An apparatus as in claim 1 and including an open ended vertically positioned cylindrical member having a reduced area lower end with a relatively small discharge opening therein, a conduit collecting overflow cereal-water mix from said tank and flowing it to the upper end of said cylindrical member, and a jet water stream supply member extending into said cylindrical member for directing the stream towards said discharge opening to aid in discharge of cereal and clean water therefrom.
Claim 4
Dependent Claim
27 words
Apparatus as set forth in claim 1 wherein the rotor is equipped with a jet hole having an axis nearly perpendicular to a radius of the rotor.
Claim 5
Dependent Claim
30 words
Apparatus as set forth in claim 1 wherein a control arm, to control the revolution of the rotor, is secured to and projects out at the side of the rotor.
Claim 6
Dependent Claim
31 words
Apparatus as set forth in claim 1 wherein the revolution of the rotor is controlled by providing a small hole in the rotor at the position symmetrical to the jet hole.
Claim 7
Dependent Claim
36 words
Apparatus as set forth in claim 1 wherein the cover fits over the cereal washing tank by aid of a holding member engaging the lower outer part of the hopper and projecting above the central opening.
Claim 8
Dependent Claim
66 words
An apparatus as set forth in claim 1 wherein the cereals are supplied from the hopper only when dropping from the top of the rotor by the revolution of the rotor, and the rotor and the head part of the tube are positioned near to the lower opening of the hopper, and the rotor is positioned in the cereal washing tank below the upper edge thereof.
