Abstract
A first rotor is fixedly carried by a shaft and a second rotor is loosely carried by the shaft. A coupling means couples the second rotor to the shaft through flanges extending from the rotor and pinching the shaft. The two rotors are then adjusted with respect to one another by rotating the shaft while holding the second rotor in place.
Claims5
In a variable resistor wherein a pair of rotors, each carrying electrical contact means, rotate while the electrical contact means engages separate resistance and collector paths, an adjustment means permitting adjustment of one rotor with respect to the other comprising:
- (a) a first rotor fixedly carried on shaft for rotation therewith,
- (b) coupling means coupled to a second rotor to said shaft for rotation therewith comprising means extending from said second rotor and pinching said shaft, and
- (c) means permitting said second rotor to be held against rotation while rotating said first rotor.
