Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
115 words
A silverware basket for use in a dishwashing apparatus having perforate bottom and peripheral walls wherein the improvement comprises: means for forming said peripheral walls including a plurality of generally upstanding ribs disposed in a first generally vertical plane and a plurality of downwardly sloping ribs disposed in a generally parallel second plane with said sloping ribs intersecting and connected to said upstanding ribs to form a latticework of perforations around said basket, the surfaces of said sloping ribs being free of horizontal planes and constructed and disposed for draining washing fluid from said basket whereby said latticework is substantially free of horizontal fluid supporting surfaces for minimizing the retention of said washing fluid thereon.
Claim 2
Dependent Claim
115 words
A silverware basket for use in a dishwashing apparatus having perforate bottom and peripheral walls wherein the improvement comprises: means for forming said peripheral walls including a plurality of generally upstanding ribs disposed in a first generally vertical plane and a plurality of downwardly sloping ribs disposed in a generally parallel second plane with said sloping ribs intersecting and connected to said upstanding ribs to form a latticework of perforations around said basket, the surfaces of said sloping ribs being free of horizontal planes and constructed and disposed for draining washing fluid from said basket whereby said latticework is substantially free of horizontal fluid supporting surfaces for minimizing the retention of said washing fluid thereon.
Claim 3
Dependent Claim
156 words
A silverware basket for retaining silverware and similar articles in a dishwashing apparatus, comprising: frame means for forming the periphery of said basket; a generally perforate bottom wall for supporting said silverware; and means for enclosing said periphery of said basket within said frame means including first and second pluralities of intersecting ribs disposed in generally vertical, parallel planes and forming a latticework of openings around said periphery, said first plurality of ribs extending generally vertically when said basket is in position for operation in said dishwasher, said second plurality of ribs extending at an angle to said first ribs and being integrally connected to said first ribs at intersecting locations, the surfaces of said first and second pluralities of ribs being free of horizontal planes and constructed and disposed for draining washing fluid from said basket whereby said latticework is substantially free of horizontal fluid supporting surfaces for minimizing the retention of washing fluid thereon.
Claim 4
Dependent Claim
156 words
A silverware basket for retaining silverware and similar articles in a dishwashing apparatus, comprising: frame means for forming the periphery of said basket; a generally perforate bottom wall for supporting said silverware; and means for enclosing said periphery of said basket within said frame means including first and second pluralities of intersecting ribs disposed in generally vertical, parallel planes and forming a latticework of openings around said periphery, said first plurality of ribs extending generally vertically when said basket is in position for operation in said dishwasher, said second plurality of ribs extending at an angle to said first ribs and being integrally connected to said first ribs at intersecting locations, the surfaces of said first and second pluralities of ribs being free of horizontal planes and constructed and disposed for draining washing fluid from said basket whereby said latticework is substantially free of horizontal fluid supporting surfaces for minimizing the retention of washing fluid thereon.
