Abstract

A housing is provided for hand-held starter motors, such as those commonly in use for starting model airplanes by imparting a torque to the spinner or nose cone of the airplane. The housing is provided with a guard to protect the hand holding the motor during the starting operation, as well as means for resting the motor on a horizontal surface without rolling. The housing comprises a cylindrical casing and an end plate through which the shaft of the starter motor extends. The end plate has a flange which extends beyond the circumference of the casing for a distance sufficient to prevent the fingers of the hand from sliding past the end plate while holding the motor. Extending from the flange of the end plate generally parallel to and overlying a portion of the outer surface of the casing is a curved protrusion having a surface which approximately fits the curve of the hand between the thumb and forefinger when the hand is holding the motor. A flat edge on one portion of the flange allows the motor to be rested on a horizontal surface without rolling. Preferably, the housing is provided with a strip switch for operating the motor, and a projection from the casing may serve as both …
