ABSTRACT:
A clutch assembly for a vacuum signature feeding device in a packer box. The clutch assembly includes a pair of disks disposed within a bore in a housing for selective driving engagement therebetween. It also includes an oscillatory motion transmitting shaft for engaging and disengaging the disk only in a preselected angular orientation therebetween for imparting oscillatory motion to one of the disks and transmitting oscillatory motion from the other of the disk when the disks are engaged. The clutch assembly is also adapted to operatively transmit the oscillatory motion to the vacuum signature feeding device. With this arrangement, reciprocating movement of the vacuum signature feeding device can be selectively interrupted without vacuum interruption.
