Abstract
Abstract A pair of cylindrical members substantially equal in diameter have a plurality of pins spaced about the periphery adjacent one edge of each cylindrical member. A spring having a ribbon of spring material with adjacent turns set to coil tightly upon each other and openings adapted to register with the pins on the cylindrical members is back wound around the cylindrical members with the pins passing through the openings in the ribbon. The ribbon is releasably secured in this back wound position. Advantageously the ribbon is releasably secured by means including a pin connecting the ends of the ribbon together.
