Kite Parachute - US3109257

William Babcock Curtis patented this "Kite Parachute" in 1961. It is probably the simplest possible kite line climber. "... the hook means being in angular relation to said member so as to be directed laterally of the kite string and disengaged therefrom when a wave motion is imparted to the string." Essentially, send it up, shake the line to create a wave, the hook will come off and the chute will drop down. Full Patent.
