Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
46 words
The apparatus of claim 1 wherein said quantity-determining means in order to determine the quantity and activate said programming means includes a relay, a switch operated by said relay and a voltage comparator adapted to operate said relay when a predetermined quantity of fiber is obtained.
Claim 2
Dependent Claim
49 words
The apparatus of claim 1 wherein said plucking means includes a picker claw adapted to repeatedly pick small amounts of fibers from any one bale, a carriage therefor adapted to position said picket claw over said bales and to raise and lower the same to come into contact therewith.
Claim 3
Dependent Claim
80 words
The apparatus of claim 3 wherein said programming means includes cams, a voltage comparator, a series of cam switches mechanically associated with each of said cams and electrically associated with said voltage comparator responsive to a predetermined position of the cam with which it is associated, said cams positioning said plucking means in accordance to said predetermined ratio as set by said voltage comparator, said cams being successively positioned upon the obtaining of each of the said minimal unit amounts.
Claim 4
Dependent Claim
120 words
The apparatus of claim 4 wherein said quantity-determining means includes a hopper carried by said carriage and adapted to receive said fibers, a potentiometer and a solenoid circuit formed by a solenoid armature and a solenoid coil, said hopper being (1) positioned beneath and traveling with said picket claw, and (2) slidably mounted with respect to its vertical travel and counterbalanced to descend as increasing weights of said fibers are received therein, said solenoid armature being fixedly attached to said hopper in slidable electrical engagement with said solenoid coil, and said solenoid coil being fixed to said carriage, the voltage of said solenoid circuit being compared to a preset voltage in said potentiometer corresponding to each said minimal unit amount.
Claim 5
Dependent Claim
39 words
The apparatus of claim 3 wherein said quantity-determining means includes a cyclic counter responsive to the number of picking strokes of said picker claw and preset to permit a certain number thereof for each of said types of fibers.
Claim 6
Dependent Claim
81 words
The apparatus of claim 1 wherein said programming means includes registering means for registering the last bale of one of said types of fibers worked on in said predetermined pattern and means responsive thereto for determining with respect to the amount of fiber already obtained of said one type whether the obtaining of an additional amount of said one type needs to be obtained and if so, for causing the plucking operation to be repeated with respect to said one type.
