Abstract:
A towbar for the towing of aircraft which will enable the user to attach the same to, selectively, the front nose wheel or the front wheel strut of an aircraft. The towbar includes a longitudinally extending towing bar with a vehicle attachment on one end thereof to facilitate attachment to a towing vehicle with the other end thereof provided with a pair of arms to engage the nose wheel or strut. The arms are openable and closeable for attachment to the wheel or strut and the mechanics for opening and closing are arranged within the longitudinal towing bar. The mechanism for opening and closing includes a slide moveable on the bar in a longitudinal direction and a structure for converting this longitudinal motion to rotational motion for rotating an arm control rod which, through a threaded end and threaded bearing will move one arm with respect to the other.
