Abstract
462,559. Parachutes. POOL, J. H. Oct. 3, 1935, No. 27321. [Class 4] A parachute incorporates an air vent in the canopy and means whereby the effective area of the vent is gradually increased automatically by deployment of the canopy and after reaching a maximum is gradually reduced by the approach of the canopy to complete deployment. In one form, a parachute includes a canopy 1 provided with an air vent 2 around which eyelets 3 are provided. Rigging lines 4 extend from the eyelets 3 and over the canopy. A closure-member 5 which is of an area sufficient to close or nearly close the vent 2 has rigging lines 7 led through the eyelets and connected to a central disc 8. A pilot parachute 9 is provided. The disc 8 may be omitted. In a modification, the disc 8 is connected to the apex of the rigging lines for the member by a frangible connection adapted to break after a predetermined time. A cord may be provided such that a manual control can be superimposed on the automatic control, and this may be replaced or combined with an automatic control in the form of a time switch whereby removal of the member 5 may be effected automatically or periodically. The movement of the member 5 may be limited by stops.
