Desinged by Charles F. Haynes of Fort Worth Texas in 1934. This is a slightly different model than Charles original design, this one features an additional "safety" ring. Charles paired his fan housing design with an Industrial motor supplied by General Electric. This example is in "as found" condition, the motor requires a spin of the blades to start. There is an oversized hole on top of the fans body, I'm unsure the purpose of the larger hole but do not believe it is original. One of the long bolts, spring, shock mount, and nut are missing. Very unique interpretation of the Airplane designs of the time period.
