In-line shift bevel gear forward/reverse

An in-line shift forward and reverse mechanism comprising:

• a first bevel gear mounted on an input shaft to be driven by said input shaft;
• a mounting means, bearings on said mounting means, said input and said output shafts mounted in said bearings;
• a second bevel gear mounted on an output shaft for driving said output shaft;
• a third bevel gear mounted on a pinion shaft for rotation thereon;
• a differential unit for mounting said pinion shaft so that said third bevel gear is in mesh with said first and second bevel gear, wherein said differential unit and/or said output shaft are rotatably driven by said input shaft;
• a stop means mounted on said differential unit for stopping said differential unit from rotation or releasing said differential unit for rotation, said stop means is a sprocket mounted on said differential unit and a stop plate wedges into said sprocket thereby stopping said differential unit;
• a means for locking said input shaft to said differential unit wherein said bevel gears are also locked relative to the input shaft;
• an in-line linkage means on said mounting means, said linkage means is connected to said stop means and said locking means, said linkage means actuating said stop means and said locking means so that when said stop means releases said differential unit for rotation, said means for locking said input shaft to said differential unit locks said bevel gears relative to said input shaft, said input shaft rotates said output shaft in the same direction but when said stop means stops said differential unit from rotation, said differential unit is not locked to said input shaft, said input shaft rotates said output shaft in the opposite direction whereby forward and reverse drive is provided.

• a stop means mounted on said differential unit for stopping said differential unit from rotation or releasing said differential unit for rotation, said stop means is a disk having holes about its periphery and a pin slidably mounted in a guide block, said pin enters said disk holes thereby stopping said differential unit, a means for locking said input shaft to said differential unit wherein said bevel gears are also locked relative to the input shaft;
• an in-line linkage means on said mounting means, said linkage means is connected to said stop means and said locking means, said linkage means actuating said stop means and said locking means so that when said stop means releases said differential unit for rotation, said means for locking said input shaft to said differential unit locks said bevel gears relative to said input shaft, said input shaft rotates said output shaft in the same direction but when said stop means stops said differential unit from rotation, said differential unit is not locked to said input shaft, said input shaft rotates said output shaft in the opposite direction whereby forward and reverse drive is provided.
