Abstract
Abstract An article handling apparatus is disclosed for feeding and transferring layers of sheet materials from one working station to another in a paper-making mill. The apparatus includes a pair of elongated rollers concentrically disposed and rotated by a chain and sprocket drive in a direction opposite to each other for gripping the article therebetween and moving the same forward toward a conveyor, means for limiting the position of feed of articles between the rollers and two pneumatic or hydraulic cylinders, one for imparting a vertical movement to one of said pair of rollers and the other for moving said means vertically into and out of the path of movement of the articles.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
138 words
An article handling apparatus comprising in combination a pair of spaced vertical supports, a motor, a sprocket and chain drive mechanism connected to said motor, means for gripping and feeding layers of sheet articles including a pair of elongated rollers disposed in opposed relationship and connected to said sprocket and chain drive for being rotated in a direction opposite to each other, a position-limiting means movable into and out of the path of movement of the articles for limiting the positioning of a layer of the articles between said rollers, a cylinder with a vertically movable rod connected to one of said pair of elongated rollers to move it along said vertical supports toward and away from the other roller and another cylinder with a vertically movable rod connected to said position-limiting means to impart vertical movement thereto.
Claim 2
Dependent Claim
138 words
An article handling apparatus comprising in combination a pair of spaced vertical supports, a motor, a sprocket and chain drive mechanism connected to said motor, means for gripping and feeding layers of sheet articles including a pair of elongated rollers disposed in opposed relationship and connected to said sprocket and chain drive for being rotated in a direction opposite to each other, a position-limiting means movable into and out of the path of movement of the articles for limiting the positioning of a layer of the articles between said rollers, a cylinder with a vertically movable rod connected to one of said pair of elongated rollers to move it along said vertical supports toward and away from the other roller and another cylinder with a vertically movable rod connected to said position-limiting means to impart vertical movement thereto.
Claim 3
Dependent Claim
74 words
The apparatus as claimed in claim 1 which further comprises means for electrically controlling the operation of the apparatus, said means including solenoid valves associated with said cylinders, a limit switch connected to said position-limiting means and disposed for abutting relation to the forward end of the layer of the sheet articles, said limit switch being arranged to energize said solenoids, and another limit switch engageable with said position-limiting means for energizing the motor.
Claim 4
Dependent Claim
26 words
