Abstract

Abstract An improved liquid handling mechanism in which a pick-up roll is actuated by eccentrics on the shaft ends to move toward and away from a liquid carrying roll to pick up liquid therefrom with the pick-up roll being maintained in a constant pressure relationship with a liquid receiving roll and transferring a uniform film of liquid thereto.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 225 words
A liquid handling mechanism comprising at least three rotatable rolls, said rolls including a liquid carrying roll and a liquid receiving roll adapted to receive liquid from the liquid carrying roll and a pickup roll for transferring the liquid from the liquid carrying roll to the liquid receiving roll, said pickup roll including shaft ends that rotate with the pick-up roll, support arm means rotatably supporting said shaft ends of said pick-up roll, means supporting said support arm means for pivotal movement about a pivotal axis substantially coextensive with the rotational axis of said liquid receiving roll, means for effecting said pivotal movement of said pickup roll about said pivotal axis toward and away from said liquid carrying roll to pick up liquid therefrom and deliver same to said liquid receiving roll including eccentric means drivingly connected with said shaft ends of said pick-up roll, said eccentric means comprising at least one eCcentric member mounted on and encircling at least one of said shaft ends, means mating with said eccentric member and supporting said eccentric member for rotation relative thereto and holding said eccentric member form bodily shifting movement relative to said liquid receiving roll, and drive means drivingly connecting said one shaft end and said eccentric member for rotating said eccentric member relative to said mating member upon rotation of said one shaft end.
Claim 2
Dependent Claim 225 words
A liquid handling mechanism comprising at least three rotatable rolls, said rolls including a liquid carrying roll and a liquid receiving roll adapted to receive liquid from the liquid carrying roll and a pickup roll for transferring the liquid from the liquid carrying roll to the liquid receiving roll, said pickup roll including shaft ends that rotate with the pick-up roll, support arm means rotatably supporting said shaft ends of said pick-up roll, means supporting said support arm means for pivotal movement about a pivotal axis substantially coextensive with the rotational axis of said liquid receiving roll, means for effecting said pivotal movement of said pickup roll about said pivotal axis toward and away from said liquid carrying roll to pick up liquid therefrom and deliver same to said liquid receiving roll including eccentric means drivingly connected with said shaft ends of said pick-up roll, said eccentric means comprising at least one eCcentric member mounted on and encircling at least one of said shaft ends, means mating with said eccentric member and supporting said eccentric member for rotation relative thereto and holding said eccentric member form bodily shifting movement relative to said liquid receiving roll, and drive means drivingly connecting said one shaft end and said eccentric member for rotating said eccentric member relative to said mating member upon rotation of said one shaft end.
Claim 3
Dependent Claim 27 words
A liquid handling mechanism as defined in claim 1 wherein said drive means comprises a drive key drivingly connecting said eccentric member and said one shaft end.
Claim 4
Dependent Claim 48 words
A liquid handling mechanism as defined in claim 1 wherein said eccentric member is rotatably supported on said one shaft end and said drive means comprises gearing drivingly interconnecting said one shaft end and said eccentric member to rotate said eccentric member relative to said one shaft end.
Claim 5
Dependent Claim 41 words
A liquid handling mechanism as defined in claim 1 further including means driving said liquid receiving roll, and said pick-up roll and said liquid receiving roll are supported in peripheral contact and said pick-up roll being rotated by said peripheral contact.
