ABSTRACT:
A ratio changing mechanism is provided for combining two mechanical input signals to produce an output signal. The mechanism includes a first crank mounted on a pivoted link with an input member mounted on the first crank. The mechanical inputs are applied to the input member which moves the crank in such a manner that an output signal is transmitted from one arm of the crank. Movement of the first crank is modified by connection of the other crank arm to a second crank which is adjustable in position to change the ratio of the output to the combined input signals.
