ABSTRACT:
A continuously variable mechanical transmission comprised of a crankshaft or similar device driven by a suitable power source such as an internal combustion engine, which drives one or more pivotally mounted levers, pushrods and ratchet mechanisms. The levers drive pushrods which in turn drive the ratchet mechanism through a rack gear mounted on each pushrod. The output of the ratchet gear mechanism drives an output shaft and is varied by varying the position of the pushrod attachment to each pivotally mounted lever. Each pushrod is connected to a slot or guide on each lever so that the connecting point can be varied from close to the pivot point or pivot axis to the opposite end of the lever. By this means it can be continuously varied from low speed to higher speed by adjusting the connecting point of the pushrods to the pivoting levers.
