ABSTRACT:
A gear drive including an input gear having alternative first and second positions and which is selectively locatable at one of the first and second positions. The input gear includes a circumferential surface having a preselected first plurality of teeth when the input gear is located at the first position and a preselected second plurality of teeth larger than the first plurality of teeth when the input gear is located at the second position. A power source is connected to the input gear for rotating the input gear at a first rotational speed when the power source is connected to the input gear at the first position and at a slower second rotational speed when the power source is connected to the input gear at the second position. Output gears engage the input gear for receiving circumferential drive from the input gear which is at substantially the same velocity with the input gear located at both the first and second positions.
