Patent ID: 7731619

Claim:
A variable motion control device, comprising: an input shaft having an input end and an output end; an output sleeve shaft having an attached unit intermediate said input end and said output end, wherein the output sleeve shaft has an opening for sleevably receiving the output end of the input shaft; a first input shaft gear attached to the input shaft; a second gear coupled to the intermediate unit, the second gear being meshably engaged with the first input shaft gear; a third gear coupled to the output sleeve shaft, the third gear being meshably engaged with the second gear; a fourth gear coupled to the intermediate unit; a control mechanism having a control mechanism gear attached to a sleeve unit including said fourth gear, said third gear meshably engaged with the fourth gear, wherein the control mechanism provides for variable control of the fourth gear via the control mechanism gear; wherein variation of the control mechanism varies motion of the fourth gear, thereby varying output of the output sleeve shaft.
