Abstract
Abstract A pair of air lines including rigid portions connected together in the form of a pantograph adapted to be carried by a vehicle in a retracted position and extended for use and having a flexible air hose connected to each end of the outer ends of the rigid portions for connection to the airplane to provide air for starting the airplane engines. A self-propelled vehicle having an air generating means and a pivoting air manifold connected to and carrying a pair of air lines including a plurality of rigid portions connected together in the form of a pantograph with means for pivoting the air manifold and means for expanding the pantograph towards an airplane and retracting the pantograph towards the vehicle for carrying with flexible air hoses connected to the outer ends and casters on one side of the pantograph for supporting the air hoses as they move along the ground.
