ABSTRACT:
A tapered, hollow, axially ribbed stem starting at its lower tip with a hard pointed tubular ferrule and terminating upwardly integrally in a windmill bladed disc disposed normal to the axis of the stem and having a diameter approximating the length of the stem, the stem being strung on a nylon string knotted at its lower end to form a stop engaging the ferrule and at its upper end to capture a glass bead on the string to constitute an upper end thrust bearing, the lower and upper extremities of the nylon string being then tied into a break formed in a kite string not far below the kite, and a parachute suspended through a glass bead bearing from a flat foam polyethylene hook having a widely flaring mouth and hooked over the lower end of the kite string to initiate the ascent of the parachute, the wind required in flying the kite blowing the hook supported parachute up the kite string and onto the ferrule, while the reaction of the windmill bladed disc to the wind is to spin the stem with an abundance of torque to cause the hook to ride upwardly along the stem until the hook reaches a level on the stem where the axial ribs thereon are of such a radius as to positively fling the hook radially from hooking engagement with the stem and thus launch the parachute into space.
