This invention relates to a rolling electrical contact assembly which is very similar to an anti-friction bearing. The contact has an inner and outer race made of a conductive material. A set of conductive rollers roll around in the space between the races. A cage (insulating) keeps the rollers in proper spaced relationship. The outer race is stationary and is composed of segments having V-shaped spaces between the segments and is connected to an electrical cable, and the inner race which rotates on a shaft is connected by a cable carried by the shaft to a suitable current destination. The segments of the outer race are spring loaded to improve the contact conductivity between the rollers and the inner and outer races.

Le présent brevet vise un assemblage de contact électrique roulant semblable en de nombreux points à un palier à roulement. Le contact est muni de chemins de roulement interne et externe faits d'un matériau conducteur. Un jeu de rouleaux conducteurs se déplacent dans l'espace séparant les chemins de roulement. Une cage isolante assure le maintien de la distance appropriée entre les rouleaux. Le chemin de roulement externe est stationnaire et se compose de segments séparés par de petits espaces en V; il est raccordé à un câble électrique et le chemin de roulement interne qui tourne sur un arbre est relié par un câble transporté par l'arbre, à un dispositif électrique approprié. Les segments du chemin de roulement externe sont montés sur des ressorts en vue d'améliorer la conductivité des contacts entre les rouleaux et les chemins de roulement interne et externe.
