Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
135 words
An endless conveyor belt construction having in combination, interengaged cross links, said links each comprising a rod having a lowered offset central portion, said central portion terminating in upwardly inclined end portions, said end portions having portions angled at right angles to said central portion and being reversely curved to form hooks disposed in planes at right angles to the axis of said rod, a rubber coating overlying said rod short of the ends thereof, and a plurality of rubber fingers spaced along said rod integral with said rubber coating and upstanding therefrom, successive of said links having said fingers disposed thereon to be in staggered relation with respect to one another, and said fingers being sufficiently resilient to yield to the weight of potatoes and to operate to nest and retain said potatoes therebetween.
Claim 2
Dependent Claim
135 words
An endless conveyor belt construction having in combination, interengaged cross links, said links each comprising a rod having a lowered offset central portion, said central portion terminating in upwardly inclined end portions, said end portions having portions angled at right angles to said central portion and being reversely curved to form hooks disposed in planes at right angles to the axis of said rod, a rubber coating overlying said rod short of the ends thereof, and a plurality of rubber fingers spaced along said rod integral with said rubber coating and upstanding therefrom, successive of said links having said fingers disposed thereon to be in staggered relation with respect to one another, and said fingers being sufficiently resilient to yield to the weight of potatoes and to operate to nest and retain said potatoes therebetween.
Claim 3
Dependent Claim
45 words
The structure set forth in claim 1, wherein said rod has an upstanding outwardly angled rubber retaining member at one end thereof, said member being integral with said rubber coating, and successive of said links respectively having said retaining members at diagonally opposed ends thereof.

The structure set forth in claim 1, wherein said fingers have height just sufficient to receive and retain potatoes therebetween.
Claim 5
Dependent Claim
19 words
The structure set forth in claim 1, wherein said links are disposed in spaced relation Longitudinally of said conveyor.
Claim 6
Dependent Claim
83 words
An endless conveyor belt construction having in combination, interengaged cross links, each link comprising a transverse rod, a rubber coating overlying each of said rods, a plurality of rubber fingers spaced along each of said rods integral with said rubber coating and upstanding therefrom, successive of said rods having said fingers disposed thereon to be in staggered relation with respect to one another, and said fingers being sufficiently resilient to yield to the weight of potatoes to nest and retain said potatoes therebetween.
Claim 7
Dependent Claim
83 words
An endless conveyor belt construction having in combination, interengaged cross links, each link comprising a transverse rod, a rubber coating overlying each of said rods, a plurality of rubber fingers spaced along each of said rods integral with said rubber coating and upstanding therefrom, successive of said rods having said fingers disposed thereon to be in staggered relation with respect to one another, and said fingers being sufficiently resilient to yield to the weight of potatoes to nest and retain said potatoes therebetween.
