Leaf vacuum/chopper
First Claim
1. An apparatus for vacuuming up and chopping material such as leaves, the apparatus comprising:
- a housing having a main chamber centered on an axis, an inlet port opening axially into the chamber, and an outlet port opening tangentially of the chamber;
a rotor disk in the chamber centered on the axis, having a hub at the axis, and having an axially directed face provided with a predetermined number of radially and axially extending and angularly spaced vanes having outer edges, at least two and at most half of the vanes being provided on their outer edges with axially outwardly projecting chopper blades having straight outer edges meeting at a point at the axis; and
means including a motor in the housing connected to the rotor disk at the hub for rotating the disk about the axis and thereby drawing the material in through the inlet, coarsely chopping the material with the blades, and expelling the coarsely chopped material with the vanes through the outlet port.

Abstract
An apparatus for vacuuming up and chopping material such as leaves has a housing having a main chamber centered on an axis, an inlet port opening axially into the chamber, and an outlet port opening tangentially of the chamber. A rotor disk in the chamber centered on the axis has a hub at the axis and having an axially directed face provided with a predetermined number of radially and axially extending and angularly spaced vanes having outer edges. At least two and at most half of the vanes are provided on their outer edges with axially outwardly projecting chopper blades. A motor in the housing connected to the rotor disk at the hub rotates the disk about the axis and thereby draws the material in through the inlet, coarsely chops the material with the blades, and expels the coarsely chopped material with the vanes through the outlet port.
