310,792. Brackett, E. M., and Brackett, F. M. April 30, 1928, [Convention date]. Delivery apparatus.-In a cutting- machine the severed sheet is removed by a delivery table reciprocated by a constantly rotating shaft through a slipping clutch controlled by the knife slide. The knife 6 is reciprocated in side guides from a crank and is connected by a pin and slot with a clampbar 15. The sliding end gauge 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 driven through a slipping- clutch 72 from a power shaft 67. A pawl 86 is adjustable on a shaft 85 actuated against spring pressure by a finger 90 on the knife slide. The ratchet cylinder comprises ratchet wheels with 1, 2, 3, &c. teeth corresponding with the grooves in the cylinder 56. By adjusting the pawl 86 to engage the appropriate ratchet wheel and setting the stops 5<1> the number of gauge setting per stroke of the gauge may be varied. A delivery table 63 is reciprocated by a crank 72<1> from a cam 102 driven through a slipping-clutch 82, Fig. 2 (not shown), from the power shaft. Movement of the cam 102 is controlled by fingers 116, 117 associated with sliding bars 118, 119 selectively actuated by adjusting pins 1<c> in extreme position in a member 125 on the shaft 33 carrying the ratchet cylinder 60. When the pins are in central position the table is not actuated.
