Adjustable nozzle for chipper-shredder vacuum
First Claim
1. A vacuum for vacuuming debris from an outdoor surface having a nozzle, an impeller assembly, and a bag, said nozzle comprising:
- an inlet for directing debris into said nozzle, said inlet having a first side, a middle section, a second side, and a non-inlet area, said first side having a first nozzle inlet, said middle section having a middle nozzle inlet, said second side having a second nozzle inlet, said first nozzle inlet, said middle nozzle inlet, and said second nozzle inlet each having a cross-sectional area, said cross-sectional area of said first nozzle inlet being greater than said cross-sectional area of said middle nozzle inlet, said cross-sectional area of said second nozzle inlet being greater than said cross-sectional area of said middle nozzle inlet; and
,an outlet, said outlet being connected to said impeller assembly.

Abstract
An adjustable nozzle for use with a chipper-shredder vacuum for vacuuming debris from an outdoor surface is disclosed. The nozzle has an inlet for directing debris into the nozzle. The inlet has a first side, a middle section, a second side, and a non-inlet area. The first side has a first nozzle inlet, the middle section has a middle nozzle inlet, the second side has a second nozzle inlet. The cross-sectional areas of the first and second nozzle inlets are greater than the cross-sectional area of the middle nozzle inlet to equalize vacuum force throughout the nozzle. The nozzle further includes a nozzle extension that extends below the nozzle and an adjustment apparatus for adjusting the height of the nozzle extension from the ground to conform the chipper-shredder vacuum to the terrain. The nozzle extension may be raised for bumpy or thick terrain or lowered for a flat terrain.
