Abstract
Abstract This invention is directed to an apparatus and method for reducing the size of a material so as to make it possible to more readily and easily handle said material and, concurrently, to make said material into a useful product. An example of this is a treatment of wood remaining in a cutover forest. The wood may be in the form of stumps, broken logs, branches, limbs and the like. This wood may be processed so as to reduce the size of the wood. The wood which has been reduced in size is left on the ground to rot. An alternative to this is to reduce the size of the wood so as to make it more easily and readily handled and then to haul this reduced size wood to a processing area or processing plant for further processing.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
124 words
A processing unit for reducing the size of wood, said unit comprising: a. a first rotor having a first passageway; b. a plurality of inwardly directed teeth on the inside surface of said first passageway for contacting said wood for tearing said wood into smaller pieces of wood; c. a means for rotating said first rotor; d. a second rotor having a second passageway; e. a plurality of inwardly directed teeth on the inside surface of said second passageway for contacting said wood for tearing said wood into smaller pieces of wood; f. said first passageway and said second passageway being in alignment for transferring said object between said first rotor and said second rotor; and, g. a means for rotating said second rotor.
Claim 2
Dependent Claim

Claim 9
Dependent Claim
119 words
A process for making a fibrous wood article, said process comprising: a. substantially simultaneously subjecting a piece of wood to a first tearing and dividing action and to a second tearing and dividing action; to produce a first fibrous wood article; b. said first tearing and dividing action and said second tearing and dividing action acting in different directions on said piece of wood; c. subjecting said first fibrous wood article to a simultaneous third tearing and dividing action and a fourth tearing and dividing action to produce a second fibrous wood article; and, d. said third tearing and dividing action and said fourth tearing and dividing action acting in substantially the same direction on said piece of wood.
Claim 10
Dependent Claim
119 words
A process for making a fibrous wood article, said process comprising: a. substantially simultaneously subjecting a piece of wood to a first tearing and dividing action and to a second tearing and dividing action; to produce a first fibrous wood article; b. said first tearing and dividing action and said second tearing and dividing action acting in different directions on said piece of wood; c. subjecting said first fibrous wood article to a simultaneous third tearing and dividing action and a fourth tearing and dividing action to produce a second fibrous wood article; and, d. said third tearing and dividing action and said fourth tearing and dividing action acting in substantially the same direction on said piece of wood.
Claim 11
Dependent Claim
64 words
A process for making a fibrous wood article, said process comprising: a. subjecting a piece of wood to a simultaneous first tearing and dividing action and a second tearing and dividing action to produce said fibrous wood article; and, b. said first tearing and dividing action and said second tearing and dividing action acting in substantially the same direction on said piece of wood.
