Abstract: 764,106. Feeding sheets. RITZERFELD, W., and RITZERFELD, G. Jan. 5, 1955 [Jan. 14, 1954], No. 313/55. Class 100(1) In a rotary duplicating machine sheets are separated from a pile on a table 16 by 'two reciprocating friction rollers 6 mounted on a shaft 7 in a holder 8 swing- able about a shaft 9, the arrangement be, ing such that on the feeding stroke the rollers are swung automatically against a braking means. The shaft 9 is mounted in a bracket 10 having edge portions against which brake rollers 11, fixed to the rollers 6, are adapted to bear on the feed stroke. The bracket 10 is mounted to swing about a shaft 12, attached to a feed member 2, which is perpendicular to the shaft 9. The member 2 is reciprocated on guide rollers by the printing drum 1 through a cam and link means. When the last sheet of the pile has been fed to the drum 1, means prevent the braking of the feed rollers 6 on the next feed strokes and, where the, machine is driven by a motor, the drive to the drum may be disabled. This means comprises a sensing member 17, rockably mounted on a shaft 4 in the member 2, which normally rides along the top sheet of the pile, but which drops through a slot in the table 16 when no sheet is present, a projection 20 on the member 17 then engaging a flange on the holder 8 to prevent it swinging towards the brake portions of the bracket 10. Also, a tip 18 of the sensing member 17 rocks a pivoted lever 22 which, through a link 24, causes a spring-loaded locking lever 25 to release a disc 26. This disc then rotates under the action of a spring to allow a lever 27 to move into the path of, and trip, a pawl 28 pivoted on the drum 1, this pawl forming part ot a one-revolution coupling driving the drum 1.
