Abstract
A double ring and radial lead assembly for electrically connecting the exterior and interior of a large, hollow shaft. A first ring secured to the shaft has a radial opening therethrough in general alignment with a radial opening in the shaft between its exterior surface and its interior surface. The first ring is secured to the shaft through an interference fit. An electrical conductor is arranged in the generally aligned openings and is secured in such position. A second conductive ring is attached to the first ring through an interference fit and covers the radially outer end of the radial lead. The second ring acts as a slip ring and provides a rotatable electrical contact surface for maintaining electrical connection with a stationary electrical source. The radially directed conductor and both rings are electrically insulated from the shaft.
