A miter gear transmission, comprising:
- a mounting platform;
- at least one bearing attached to said mounting platform;
- an idler cluster, said idler cluster having first and second gear sets, first and second ends, a center point disposed between said first and second ends and being rotatably mounted to said at least one bearing;
- said first gear set comprising a plurality of gears, said gears having decreasing numbers of gear teeth and being attached to said idler cluster from a point adjacent said center point outwardly toward said first end with those gears having a largest number of teeth closest to said center point and with those gears having a smallest number of teeth closest to said first end;
- said second gear set comprising a plurality of gears, said gears having decreasing numbers of gear teeth and being attached to said idler cluster from a point adjacent said center point outwardly toward said second end with those gears having a largest number of teeth closest to said center point and with those gears having a smallest number of teeth closest to said second end;
- a driving shaft, said driving shaft having a first end, a second end, a first rotational securing means and being mounted at said first and second ends in bearings attached to said mounting platform;
- said driving shaft being mounted at a forty-five degree angle to said idler cluster;
- a first spur gear, said first spur gear being slidably mounted to said driving shaft and having a first mating rotational securing means slidably engaging said first rotational securing means;
- a first actuator, said first actuator moving said first spur gear along said driving shaft to engage alternately each of said gears of said first gear set;
- a driven shaft, said driven shaft having a first end, a second end, a second rotational securing means and being mounted at said first and second ends in bearings attached to said mounting platform;
- said driven shaft being mounted at a forty-five degree angle to said idler cluster;
- a second spur gear, said second spur gear being slidably mounted to said driven shaft and having a second mating rotational securing means slidably engaging said second rotational securing means;
- a second actuator, said second actuator moving said second spur gear along said driven shaft to engage alternately each of said gears of said second gear set;
- and
- whereby, when said first actuator positions said first spur gear to engage one of said gears of said first gear set and said second actuator positions said second spur gear to engage one of said of gears of said second gear set, said driving shaft will rotate said idler shaft which will rotate said driven shaft at a speed determined by the ratios selected by said first and second actuators.
