SINGLE CONTROL, VARIABLE SPEED DRIVE

A mechanical, infinitely variable speed drive is provided with reverse actuation and a single control lever. The drive includes a shaft with an output gear and two driven, face-to-face bevel gears. Shifting mechanism connects either or neither bevel gear to the shaft. A drive bevel gear engages both driven bevel gears and is driven through variable speed pulleys. A cam plate operates the shifting mechanism and a cam manipulates the variable speed pulleys. Both the cam plate and the cam are controlled by a single control lever. The output can be through a differential with the bevel gear shaft being hollow and rotatably mounted on one of the axles of the differential.
