MORE EFFICIENT OPERATION OF KEARNY AIR PUMPS FOR MANUAL VENTILATION OF SHELTERS.

The following developments and tests pertinent to more efficient design and operation of Kearny Air Pumps (KAP's) when used to ventilate and cool shelters are described: (l) Demonstration of the unreliability of a KAP when operated in the doorway of a dead-end shelter room; (2) Development and tests of a technique for using an A-Frame Kearny Air Pump to efficiently ventilate a dead-end shelter; (3) Development and tests of improved handles and bridles with which to pull especially 6foot KAP's that must be pulled directly, without the help of a pulley attached above the operator(s); {k) Perfection of illustrated written instructions to enable average Americans to operate KAP's efficiently, when guided only by these written instructions; (5) Determination of the preference of average citizens for pulling a 6-foot KAP with its pull-cord connected 15 inches from its hinge line, as compared with its pull-cord connected 3 feet from its hinge line; (6) Improvement of the durability of the flaps for KAP's; (7) Development of means for protecting homemade KAP's that are being operated inside shelters from being damaged by a moderate velocity Shockwave and blastwind entering the shelter.
