Abstract
499,409. Parachutes. HART, R. P. July 29, 1937, No. 20950. [Class 4] A parachute comprises a chamber or chambers attached to or incorporated in the canopy, the chamber or chambers being capable of inflation by the air under pressure contained in the canopy during descent and of remaining inflated after descent. As shown, the canopy C is provided with a chamber A surrounding the air vent D. The chamber has waterproof fabric walls and is in communication with the interior of the canopy by means of one-way valves B which may be flap valves, treated to be impervious to water, or mushroom valves, the spring loading of which is such as to allow them to open under air pressure during the initial period of the descent but to keep them closed during the rest of the descent.
