Abstract
A drive mechanism for converting rotary movement to an oscillatory movement for operating switches, valves, pumps and light implements wherein the oscillating member is a flexible rod having a curved profile from which to attach output levers positioned in a simple manner to vary the amplitude, phase timing, and duration of stroke of individual output levers; whereby numerous output functions may be performed from a single rotary input source.
Claims8
A device for converting rotary movement into reciprocating movement employed to operate light implements including pumps, valves and switches comprising
- (a) a rotatable driving means;
- (b) a crank arm rigidly secured to said rotatable driving means;
- (c) a flexible rod made of helically wound wires secured fixedly at a distance from said crank arm in substantially same axis as said rotatable driving means;
- said flexible rod journalled eccentrically in said crank arm and,
- (d) at least one lever attached perpendicular to said flexible rod whereby rotary movement in said rotatable driving means produces reciprocating motion in said at least one lever.
