Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
87 words
A mixing device comprising a pail, a pair of vertically disposed, planar baffles attached to the bottom of the pail, said baffles being oppositely directed with respect to each other and being symmetrically disposed with respect to an imaginary, vertical, diametral plane extending through said pail, said baffles having inner end portions disposed in overlapping relation to each other, and said baffles having inwardly and downwardly inclined inner edges which when viewed in a direction normal to said diametral plane jointly define a generally bowl-shaped baffle-free space.
Claim 2
Dependent Claim
87 words
A mixing device comprising a pail, a pair of vertically disposed, planar baffles attached to the bottom of the pail, said baffles being oppositely directed with respect to each other and being symmetrically disposed with respect to an imaginary, vertical, diametral plane extending through said pail, said baffles having inner end portions disposed in overlapping relation to each other, and said baffles having inwardly and downwardly inclined inner edges which when viewed in a direction normal to said diametral plane jointly define a generally bowl-shaped baffle-free space.
Claim 3
Dependent Claim
28 words
The mixing device of claim 1, said baffles being provided with flow-through apertures and having their outer edges disposed in spaced relation to the side of said pail.
Claim 4
Dependent Claim
34 words
The mixing device of claim 1, said pail being provided with a handle whereby said pail may be suspended and rotationally twirled back and forth to effect a mixing of liquid within the pail.
Claim 5
Dependent Claim
115 words
A mixing device comprising a pail, a pair of vertically disposed, planar baffles attached to the bottom of the pail, said baffles being oppositely directed with respect to each other and being spaced apart with respect to each other, said baffles being removably attached to the bottom of said pail by means comprising threaded stud elements fixedly attached to the bottom of the pail, a foot flange on each baffle, one of said foot flanges being disposed in superposed relation to the other of said foot flanges, said flanges being provided with apertures for said stud elements, and wing nuts threadably attached to said stud elements in clamping relation with respect to said foot flanges.
Claim 6
Dependent Claim
115 words
A mixing device comprising a pail, a pair of vertically disposed, planar baffles attached to the bottom of the pail, said baffles being oppositely directed with respect to each other and being spaced apart with respect to each other, said baffles being removably attached to the bottom of said pail by means comprising threaded stud elements fixedly attached to the bottom of the pail, a foot flange on each baffle, one of said foot flanges being disposed in superposed relation to the other of said foot flanges, said flanges being provided with apertures for said stud elements, and wing nuts threadably attached to said stud elements in clamping relation with respect to said foot flanges.
Claim 7
Dependent Claim
33 words
The mixing device of claim 1, the distance of overlap of the inner end portions of said baffles exceeding the distance between said baffles measured along a line normal to said diametral plane.
