Abstract: A helically coiled flexible electrical conductor extensible and retractable axially to provide electrical connection to a movable element is slidably supported by a rod which extends through it, one end of the coil being fixed and the other end movable. A tube slidably fitted on the rod extends from the movable end through convolutions of the coil and is movable with the movable end of the coil. A knob carried by the rear end of the tube controls the escape of convolutions from the tube during forward movement.

Abstract: A helically coiled flexible electrical conductor extensible and retractable axially to provide electrical connection to a movable element is slidably supported on a rod which extends through it. Convolutions at the movable end of the coil also overengage a controlling member movable with the movable element and which limits forces exerted upon portions of the conductor close to its movable end.
