  • Arrangement for rotating the shaft of an electrical component
    Patent number: 4507979
    Abstract: An arrangement for adjusting the angular position of a shaft, such as a potentiometer shaft, by frictional coupling to a driving shaft. Grooved pulleys are mounted on each of the shafts, and a tensioned cord is wrapped in a figure of eight fashion about the two grooves. The shafts are spaced apart a distance equal to the sum of the pulley rim radii, and the cord tension holds the pulley rims together in frictional engagement. In studio control panel applications, the driving pulley may be five times the radius of the driven pulley.
