Under basic patents...:
“Will Defy the laws of Gravitation
Under basic patents granted to W. Pitts of Los Angeles California., W.P. Kindree has developed this unique helicopter with which he hopes to take to the air shortly. The motor, not yet installed, weighs 235 pounds and develops 65 horse power. The mushroom propellor composed of sixty blades may be tipped 45 degrees in any direction, which means that after the plane once gains altitude it may be flown in the manner of an ordinary plane. The mushroom rotates and reciprocates 20 inches with each revolution. 29/10.30”
