8 Claims. (01. 135-1)
The ‘present ‘invention relates to a tower enclo
sure adapted for drying parachutes singly or en
masse ‘having for its objects generally stated, pro
viding a tower enclosure having a number of rope
pulleys at its top suitably spaced and means
whereby the .top of the parachutes may be at
tached to one end of a rope and pulled to the
top of the tower for drying.
