Abstract
Abstract Washing of eggs utilizing reciprocating brushes with the brushes tilted at an angle in the order of about 30*-60* from the vertical and having bristles of progressively shorter length in the direction of lean of the tilted brushes. The brushes are mounted for opposed reciprocation on mountings producing a natural frequency of vibration approximating the driven frequency.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
64 words
A METHOD OF WASHING EGGS COMPRISING THE STEPS OF MOVING EGGS ON A CONVEYOR BENEATH A PAIR OF STRIPS BRUSHES TILED FROM THE VERTICAL POSITION IN ORDER OF ABOUT 30*-60*, HORIZONTALLY RECIPROCHING THE BRUSHES IN OPPOSITE DIRECTION FROM EACHAOTHER WHILE MAINTAINING SAID BRUSHES IN THE POSITION TILTED FROM THE VERTICAL, WHILE THE EGGS MOVE THEREUNDER, AND SIMULTANEOUSLY SPRAYING A WASHING SOLUTION ONTO THE EGGS.
Claim 2
Independent Claim
64 words
A METHOD OF WASHING EGGS COMPRISING THE STEPS OF MOVING EGGS ON A CONVEYOR BENEATH A PAIR OF STRIPS BRUSHES TILED FROM THE VERTICAL POSITION IN ORDER OF ABOUT 30*-60*, HORIZONTALLY RECIPROCHING THE BRUSHES IN OPPOSITE DIRECTION FROM EACHAOTHER WHILE MAINTAINING SAID BRUSHES IN THE POSITION TILTED FROM THE VERTICAL, WHILE THE EGGS MOVE THEREUNDER, AND SIMULTANEOUSLY SPRAYING A WASHING SOLUTION ONTO THE EGGS.
Claim 3
Dependent Claim
26 words
The method of washing eggs in accordance with claim 1, further characterized by said position of tilt of the brushes being approximately 30* from the vertical.
Claim 4
Dependent Claim
38 words
The method of washing eggs in accordance with claim 1, further characterized by spring mounting of said brushes, and driving the reciprocating brushes at a frequency approximately at their natural frequency of vibration due to their spring mounting.
Claim 5
Dependent Claim
87 words
A machine for washing eggs comprising means to apply a washing solution on the eggs, conveyor means to move the eggs being washed through the machine, at least one pair of brushes tilted from the vertical position in the order of about 30*-60* mounted above said conveyor means, means to reciprocate said brushes horizontally with each one of said pair of said brushes moving in an opposite transverse direction from the other one of said pair in relation to the direction of movement of said conveyor means.
Claim 6
Dependent Claim
87 words
A machine for washing eggs comprising means to apply a washing solution on the eggs, conveyor means to move the eggs being washed through the machine, at least one pair of brushes tilted from the vertical position in the order of about 30*-60* mounted above said conveyor means, means to reciprocate said brushes horizontally with each one of said pair of said brushes moving in an opposite transverse direction from the other one of said pair in relation to the direction of movement of said conveyor means.
Claim 7
Dependent Claim
25 words
The machine of claim 4, further characterized by said brushes having bristles of progressively shorter length in the direction of tilt from the vertical position.
Claim 8
Dependent Claim
90 words
The machine of claim 4, further characterized by said means to reciprocate said brushes including transverse beams supporting said bushes, at least two movable frames supporting said brush supporting transverse beams, each of one of said pair of brushes being supported by a said transverse beam supported by one of said frames, and the other of said pair of brushes being supported by a said transverse beam supported by another of said frames, and means to move said movable frames in a reciprocal movement in opposite directions to each other.
Claim 9
Dependent Claim
46 words
The machine of claim 6, further characterized by said means to move said movable frames including lever means pivotally connected to each of said at least two movable frames, one of said lever means connected to an opposed eccentric drive from another of said lever means.
Claim 10
Dependent Claim
16 words
The machine of claim 6, further characterized by said movable frames mounted on spring flexure mountings.
Claim 11
Dependent Claim
28 words
The machine of claim 8, further characterized by said spring flexure mountings producing a natural frequency of vibration of said frames approximating the driven frequency of said frames.
