Abstract
Abstract A device for chopping or cutting up brush garden trimmings and other waste material to a size suitable for use as a mulch or compost comprises a mounting plate with edge means for securing it like a removable cover on a container. An opening on one side of the plate is spaced radially from its center and feed means are provided around the opening for directing the material through it. Centrally mounted on the plate is a motor whose shaft extends to the underside of the plate. A cutting blade is fixed to the shaft and operates with a fixed blade near the opening to cut up materials forced through it.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
137 words
A portable device for cutting brush and shrub trimmings into relatively small particles suitable for use as a soil mulch, comprising: a disclike plate member forming a cover for a portable container to catch and collect the cut material having a first, relatively small opening and a second larger opening spaced from said first opening; an electric motor of no more than 0.5 HP fixed to the upper side of said plate member having an output shaft extending downwardly through said first opening therein; a rotary cutting member having enlarged cutting end portions passing under said second opening fixed to said output shaft; means carried by and adjacent the plate member for controlling the feeding of brush material through said second opening; and means on said plate member for readily detachably retaining it on said portable container.
Claim 2
Dependent Claim
137 words
A portable device for cutting brush and shrub trimmings into relatively small particles suitable for use as a soil mulch, comprising: a disclike plate member forming a cover for a portable container to catch and collect the cut material having a first, relatively small opening and a second larger opening spaced from said first opening; an electric motor of no more than 0.5 HP fixed to the upper side of said plate member having an output shaft extending downwardly through said first opening therein; a rotary cutting member having enlarged cutting end portions passing under said second opening fixed to said output shaft; means carried by and adjacent the plate member for controlling the feeding of brush material through said second opening; and means on said plate member for readily detachably retaining it on said portable container.
Claim 3
Dependent Claim
30 words
The device as described in claim 1 wherein said latter means for retaining said plate member comprises a downwardly extending wall member integral with the periphery of said plate member.
Claim 4
Dependent Claim
32 words
The device as described in claim 1 wherein said plate member has a circular shape and said means for retaining it on a container is a cylindrical wall member around its periphery.
Claim 5
Dependent Claim
58 words
The device as described in claim 1 wherein said means for controlling the feeding of material through said second opening comprises a pair of side wall members on opposite sides of said second opening, an end wall between said side wall members, a fixed roller extending partially through said end wall, and means for rotating said fixed roller.
Claim 6
Dependent Claim
41 words
The device as described in claim 4 including a pivotal plate forming a guard means, and spring means attached to said pivotal plate normally urging it to a position whereby it covers said second opening when no material is passing therethrough.
Claim 7
Dependent Claim
26 words
A device as described in claim 1 including a cutter member fixed to the plate member adjacent said second opening cooperating with said rotary cutting member.
Claim 8
Dependent Claim
23 words
The device as claimed in claim 1 wherein the means for controlling the feeding of material through said second opening comprises roller means.
Claim 9
Independent Claim
155 words
A device for cutting brush and shrub trimmings into relatively small particles suitable for use as a soil mulch, comprising: a disclike plate member having a first relatively small opening and a second larger opening spaced from said first opening; a power unit fixed to the upper side of said plate member having an output shaft extending downwardly through said first opening therein; a rotary cutting member fixed to said output shaft; means for controlling the feeding of brush material through said second opening; and means on said plate member for retaining it on a container adapted for catching and collecting the cut up material, said means for controlling the feeding of material through said second opening comprising a pair of side wall members on opposite sides of said second opening, an end wall between said side wall members, and fixed roller extending partially through said end wall, and means for rotating said fixed roller.
Claim 10
Independent Claim
155 words
A device for cutting brush and shrub trimmings into relatively small particles suitable for use as a soil mulch, comprising: a disclike plate member having a first relatively small opening and a second larger opening spaced from said first opening; a power unit fixed to the upper side of said plate member having an output shaft extending downwardly through said first opening therein; a rotary cutting member fixed to said output shaft; means for controlling the feeding of brush material through said second opening; and means on said plate member for retaining it on a container adapted for catching and collecting the cut up material, said means for controlling the feeding of material through said second opening comprising a pair of side wall members on opposite sides of said second opening, an end wall between said side wall members, and fixed roller extending partially through said end wall, and means for rotating said fixed roller.
Claim 11
Dependent Claim
41 words
The device as described in claim 8 including a pivotal plate forming a guard means, and spring means attached to said pivotal plate normally urging it to a position whereby it covers said second opening when no material is passing therethrough.
Claim 12
Dependent Claim
21 words
The device as described in claim 9 including a roller carried by said pivotal plate and cooperating with said fixed roller.
