Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
134 words
Tray apparatus comprising a frame an array of closely spaced tray members supported by said frame in vertical alignment, each of said tray members having a first wall portion extending in a direction inclined to the horizontal plane, and a second wall portion extending in a direction inclined to the vertical plane from said first wall portion at right angles thereto, said wall portions in vertical alignment defining a nested relationship, wherein each of said tray members includes a third wall portion extending in the horizontal plane, wherein each of said tray members has mounting means connected thereto, said mounting means including a resilient member to enable movement of said tray members relative to said frame, wherein said mounting means includes cam follower means which guide said tray members in a generally vertical path.
Claim 2
Dependent Claim
134 words
Tray apparatus comprising a frame an array of closely spaced tray members supported by said frame in vertical alignment, each of said tray members having a first wall portion extending in a direction inclined to the horizontal plane, and a second wall portion extending in a direction inclined to the vertical plane from said first wall portion at right angles thereto, said wall portions in vertical alignment defining a nested relationship, wherein each of said tray members includes a third wall portion extending in the horizontal plane, wherein each of said tray members has mounting means connected thereto, said mounting means including a resilient member to enable movement of said tray members relative to said frame, wherein said mounting means includes cam follower means which guide said tray members in a generally vertical path.
Claim 3
Dependent Claim
137 words
Tray apparatus comprising a frame an array of closely spaced tray members supported by said frame in vertical alignment, each of said tray members having a first wall portion extending in a direction inclined to the horizontal plane, and a second wall portion extending in a direction inclined to the vertical plane from said first wall portion at right angles thereto, said waLl portions in vertical alignment defining a nested relationship, wherein said first wall portions are inclined to the horizontal plane at an angle ranging from about 5* to about 35*, wherein said tray members are mounted on said frame in groupings, means on said frame mounting each grouping so that the groups are separated from each other by a space larger than the space between individual tray members to enable multiple unloading of tray members.
Claim 4
Dependent Claim
