Edger fan apparatus

Claim 1

In combination with an edger having a housing mounted on wheels for movement across hard, substantially planar surfaces such as cement sidewalks, a motor mounted on said housing, said motor causing rotation of an output shaft, a cutting blade driven by said output shaft, said cutting blade being adapted to cut vegetation located directly adjacent an edge of said hard, substantially planar surface, the improvement comprising; fan means mounted on said housing in close proximity to said cutting blade but spaced therefrom, said fan means to be rotatably driven by power means; said fan means including a plurality of separate fan blades, each said fan blade being formed of a flexible sheet material, each said fan blade being connected to a fan hub by means of a flexible connection, said hub comprising a spool forming an inner disc and an outer disc, each said fan blade being connected to both said inner disc and said outer disc, each said flexible connection permitting movement of its respective fan blade with respect to said hub within the plane of rotation of said fan means, whereby upon a fan blade contacting an exterior object such as a users hand or leg the fan blade will readily bend causing little or no injury to the user; a shaft extension being fixedly mounted to said output shaft, said hub being slidably mounted upon said shaft extension, said hub having a forwardmost planar surface, a washer member connected to said shaft extension having an inner planar surface, said forwardmost planar surface being in continuous frictional contact with said inner planar surface, said hub being normally rotatably driven with said shaft extension but capable of sliding movement in respect thereto upon encountering a restricting force; and coil spring biasing means located between said hub and a stop means on said shaft extension, said blasing means exerting a continuous force against said hub to frictionally engage together said forwardmost planar surface and said inner planar surface to cause said hub to normally rotate with said shaft extension.
