Abstract:
1. A transmission apparatus comprising: a first main gear rotationally attached to a support and capable of being driven by a first drive; a second main gear being coaxial to the first main gear and rotationally attached to the first main gear, the second main gear geared to a roller drive gear and being driven by a second drive; a linear drive in which an elongated device is engaged along an axis of rotation of the elongated device, the linear drive coupled to the first main gear, when the first main gear is rotated, the elongated device is rotated about the elongated device's axis of rotation, the linear drive being geared to the roller drive gear, when the second main gear is rotated the linear drive imparts linear motion to the elongated device; and the first main gear including a first slot extending from an outer perimeter of the first main gear to the center of the first main gear and the second main gear including a second slot extending from an outer perimeter of the second main gear to the center of the second main gear, the first and second slots being aligned in a common plane in a first position, the elongated device being removably received into the linear drive through the first slot and second slot when the first and second gears are in the first position.
