My invention relates to improvements in para
chutes, the primary object in View being to equip
A relatively small, auxiliary umbrella section 9,
substantially circular with the exception present
such devices for quick, easy and safe control, as
regards both speed and direction in descending,
ly noted, is provided on the under side of the um..
brella I and which is of sufficient size to close said
and also for easy control of the same on the
vent opening 3_ and overlap the edge of the same
so as to be compressed against said edge under
pressure of air in the umbrella I and thereby seal
Other and subordinate objects are also com
said opening 3 around the edges thereof.

The auxiliary umbrella section 9 is also formed
with the precise nature of my improvements, will

of the auxiliary umbrella section a'way from the
edge of said vent opening 5 all around said edge,
as Ishown in Figure 7, the parachute may be
caused to quickly descend with a suddenly ac

auxiliary umbrella section 9 opposite to that
vshown in Figure 6, as similarly manipulated, away
from the edge of the vent opening 5, the para
chute may: becaused to,I descend with an acceler

the showing in Figure 5.
As will be seen, the vent opening 5 and the
edge thereof, together with the auxiliary umbrellaì
