the clamp frame 24 by an advance mount 88 preferably the advance air cylinder 32 is mounted generally parallel with the drive shaft 74 and drive shaft housing 72 an advance extension rod 90 that is longitudinally extendable from the forward end of the advance air cylinder 32 is attached to a size plate 92 that extends downward from the advance extension rod 90 and engages the gear housing 62 a tilt air cylinder 34 is mounted on the clamp frame 24 preferably with the tilt air cylinder longitudinal axis located generally perpendicular to the drive shaft 74 and drive shaft housing 72 the tilt extension rod 94 is longitudinally extendable from within the tilt air cylinder 34 when extended the tilt extension rod 94 communicates force to the tilt arm 84 an orient extension rod 96 extends longitudinally from the orient cylinder 36 positioned generally parallel with the drive shaft housing 72 the orient extension rod 96 extends rearwardly through an orient mount 76 second opening 98 and an orient arm 82 second opening 100 the orient extension rod 96 is secured to the rear side of the orient arm 82 in operation the controller 8 opens air valves to supply compressed air to the air cylinders in an appropriately timed order to effect the following sequence from an assumed starting position wherein the orient pins 66 engage a properly aligned button that lies in the loading position in the button path 44 of the chute 38 when provided with a supply of compressed air the advance air cylinder 32 forces the advance extension rod 90 forward which causes the size plate 92.
