Abstract
The output centerpoint of a Cardan gear mechanism is connected via a ball and a pin slideable therethrough to a lever which in turn carries a looper. Because the major axis of the lever and the axis swept out by the output centerpoint are skewed the lever is reciprocated back and forth along its own major axis while being rotated therearound. This results in the looper being swept back and forth along part of a generally helical-like path.
