ABSTRACT:
A universal blower unit is provided which may be directly attached to any of the most widely distributed flexible line type grass or weed trimming tools, known as "Line-Trimmers" and sold under various designations including under the trademark "WEED EATER". The blower unit is secured to the motor housing following removal of the unit which normally holds the line employed in the line trimming operation. In securing the blower unit in place, a series of spacing studs are employed to orient and prevent lateral movement of the blower unit, and spring clamps extend up over the housing to hold the blower unit onto the motor housing and to hold the impeller in driving engagement with the output drive shaft from the motor. A small supplemental impeller is located adjacent the motor for cooling purposes. The blower unit is spaced downwardly from the motor housing and air is drawn in through the space between the blower and the motor housings. A nozzle is provided to direct a jet of air forward from the blower apparatus to sweep sidewalks or other paved or unpaved surfaces free from clippings and the like.
