  "abstract": "A cyclicly repetitive motion generating system utilizing first and second drive members mounted respectively on first and second spaced axes and including an oscillating member pivotally mounted about the axis of one of said drive members carrying multiple idler means with a continuous loop of flexible drive means in tangential driving engagement with the first and second drive members and in engagement with said idler means, and a link connecting one of said drive members and said oscillating member wherein rotation of the drive members will cause an oscillation of the oscillating member about its axis. The result is a mechanism capable of generating repetitive index cycles consisting of a short dwell, a smooth acceleration to a maximum velocity and a smooth deceleration to a following dwell.",
