Abstract
A hand-held blower and adjustable blower nozzle attachment is disclosed for providing a variable rate air flow discharge from the nozzle attachment. The blower includes a housing having a handle, a discharge portion and a motor with an operatively connected impeller within a chamber connected to the discharge portion. A tubular body is attached to the discharge portion at one end and a blower nozzle attachment at a second end. The blower nozzle attachment includes at least one constrictor flap provided within the nozzle attachment body to change the air flow rate between a low air velocity rate in a first position and a higher air velocity rate in at least one second position. The adjustable blower nozzle attachment is provided with at least one aperture corresponding to the at least one constrictor flap for adjustment of the flap between the first and the at least one second position. A control is rotatably mounted to the nozzle body and includes a member mounted within the nozzle body to return the at least one constrictor flap from the at least one second position to the first position. Alternatively, the control may be slidably mounted to the nozzle attachment body. A member is pivotally connected to both the control and the at least one constrictor flap to move the at least one constrictor flap between the first and the at least one second position.
