297,105. Brackett, E. M., and Brackett, F. M., (Assignees of Daneke, D.). Sept. 16, 1927, [Convention date]. Delivery apparatus.-In a cutting machine the sheet to be severed is positioned by a movable gauge controlled by adjustable stops on a cylinder rotated through a slipping clutch from a constantly rotating shaft, when freed by a detent actuated from the knife slide. The knife 6 is reciprocated in side guides from a crank 16 and is connected by a pin and slot with a clamp-bar 24. An end gauge for the sheet is positioned by a finger on the gauge engaging stops 5<1> adjustable in grooves in a cylinder 56. A sectional ratchet cylinder 60 is connected through a slipping clutch 72 with a constantly rotated shaft 67. A pawl 86 is adjustable on a shaft 85 to release one of the ratchets on cylinder 60 when the shaft is rocked against spring pressure by a finger 90 on the knife slide. The ratchet cylinder 60 comprises wheels with 1, 2, 3, &c. teeth. By adjusting the pawl to engage the appropriate wheel and setting the stops 5<1> the number of gauge settings per stroke of the gauge may be varied. A delivery table is mounted on a pivoted arm connected by a rod 98 to a cam plate 102 on a shaft 101 rotated through a slipping clutch from a power shaft. Movement of the cam 102 is controlled by fingers 116, 117 associated with sliding bars 118, 119 which are selectively actuated by adjusting pins 1<c> in extreme positions in a member 125 on the cylinder 60. When the pins are in central position the delivery table is not actuated.
