work the sequence means or as shown a button delivering and removing assembly means 30 has mounted thereon a button conveyor means 61 which is rotatable through a work cycle that is between an initial position and an indexed position the driving force for rotating the button conveyor means 61 will now be described as disclosed in detail in the bowin u s pat no 3 749 041 shaft means 66 is driven by a looper shaft not shown which is driven from the main shaft 32 securely fastened to shaft means 66 is off center cam means 65 drive lever pusher means 68 has an elongated slot 64 journalled by drive shaft means 66 the drive lever pusher means 68 is secured in an adjacent sliding relationship with the off centered cam means 65 such that a tab means 70 extending from one end of the elongated slot always maintains contact with the outer peripheral surface means 67 of the eccentric cam as is apparent when the eccentric cam means 65 passes through a complete revolution the drive lever pusher means 68 will reciprocate from the left to the right this movement taking place as long as the tab means 70 slides on the outer circumference means 67 the indexing drive force is transferred to drive lever means 80 via support pin means 81 drive lever means 80 is pivotally mounted fig2 at first end means on shaft means 82 at second end means 83 fig1 is a horizontally extending connecting rod means which transfers the driving force to the button delivering and removing assembly 30 in the operation of the machine as the main shaft 32 is rotated.
