Propeller spinner for model airplanes or the like

A spinner for use with a model airplane, or the like, which has a propeller on a propeller shaft, the propeller having propeller blades with shanks, and the propeller being disposed between a thrust plate fixed to the propeller shaft and retaining means such as a propeller nut threaded onto the propeller shaft, comprising:

• a base plate having a passage for receiving the propeller shaft axially therethrough, said base plate being positionable between the thrust plate and the propeller and held in such assembly for conjoint rotation by said propeller nut;
• an air piercing nose cone located forwardly of the propeller and having a base portion engageble with said base plate, said nose cone having radial openings for receiving the shanks of the propeller blades;
• a generally flat, disc shaped locking ring rotatably mounted on said base plate for rotation about the axis of the propeller shaft for movement relative to the base plate between a locking position and a release position, said locking ring having at least one locking edge;
• and
• engaging means on said nose cone comprising at least one interior stud having a radial notch for engagement therein by said locking edge of said locking ring when the locking ring is in said locking position to hold the nose cone on said base plate for conjoint rotation therewith, said locking edge being movable out of said radial notch when in said release position to permit the nose cone to be readily removed for access to said retaining means.

A spinner for use with a model airplane, or the like, which has a propeller on a propeller shaft and retaining means for securing the propeller to the shaft, comprising:

• a base plate having a passage for receiving the propeller shaft axially therethrough, with said propeller and said retaining means being disposed axially outwardly of said base plate;
• an air piercing nose cone located forwardly of the propeller and engageable with said base plate;
• locking means mounted on said base plate for movement relative thereto beteen a locking position and a release position;
• and
• engaging means on said nose cone complementarily engageable by said locking means when in said locking position to hold the nose cone on said base plate for conjoint rotation therewith, said engaging means being disengaged by said locking means when in said release position to permit the nose cone to be readily removed for access to said retaining means.
