Abstract
Abstract A transversely slotted belt for a down cotton retrieving system includes a plurality of spaced, protruding island-like pads disposed along the outer surface of the belt. Each of the protruding pads is substantially bisected by one of the transverse slots, thereby forming separated pairs of opposed flexible fingers. The size, spacing, flexibility, and shape of the pairs of fingers are selected to produce a pinching action which optimizes the grasping efficiency and grasping selectivity of the bisected island-like pads during retrieving of down cotton.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
149 words
A flexible cotton retrieving belt for use in a cotton retrieving system including an upper pulley and a lower pulley for supporting said belt, said belt comprising in combination: a. a plurality of transverse slots disposed in spaced relationship along the outer surface of said belt for opening when said belt is flexed as said belt passes over said pulleys and closing when said belt straightens as said transverse slots move away from said pulleys; and b. a plurality of island-like pads disposed along the outer surface of said belt, each of said island-like pads being substantially bisected by one of said transverse slots and separated from the others of said island-like pads by shallow valley-like gaps; whereby, said island-like pads selectively close upon and grasp tufts and/or fibers of down cotton on or embedded in the ground as said belt passes around and away from said lower pulley.
Claim 2
Dependent Claim
149 words
A flexible cotton retrieving belt for use in a cotton retrieving system including an upper pulley and a lower pulley for supporting said belt, said belt comprising in combination: a. a plurality of transverse slots disposed in spaced relationship along the outer surface of said belt for opening when said belt is flexed as said belt passes over said pulleys and closing when said belt straightens as said transverse slots move away from said pulleys; and b. a plurality of island-like pads disposed along the outer surface of said belt, each of said island-like pads being substantially bisected by one of said transverse slots and separated from the others of said island-like pads by shallow valley-like gaps; whereby, said island-like pads selectively close upon and grasp tufts and/or fibers of down cotton on or embedded in the ground as said belt passes around and away from said lower pulley.
Claim 3
Dependent Claim
19 words
The cotton retrieving belt of claim 1 wherein the ground-contacting surfaces of said island-like pads are substantially oval shaped.
Claim 4
Dependent Claim
18 words
The cotton retrieving belt of claim 1 wherein the ground-contacting surfaces of said island-like pads are substantially rectangular.
Claim 5
Dependent Claim
14 words
The cotton retrieving belt of claim 2 wherein said valley-like gaps are substantially rounded.
Claim 6
Dependent Claim
14 words
The cotton retrieving belt of claim 3 wherein said valley-like gaps are substantially V-shaped.
