Total Claims: 6
Claim 1
Independent Claim
159 words
A woodcHipping machine for chipping logs or the like into chips which is characterized by: a. a supporting surface of a rotatable sheet member, b. a plurality of cutting elements mounted radially and angularly spaced on said supporting surface, c. a plurality of holes in said sheet member, each hole being located adjacent a cutting element so that any chips formed by said cutting elements may pass through said holes, d. a re-inforcing structure comprising 1. a second member spaced from said first member on the side of said first member remote from said supporting surface, said second member comprising through passages, 2. channel members structurally connecting said first and second members and forming passages from said holes of said first member to said through passages of said second member, so that any chips formed may pass to the side of said second member remote from said first member via said holes, said channel members and said through passages.
Claim 2
Dependent Claim

Claim 4
Dependent Claim
56 words
channel members structurally connecting said first and second members and forming passages from said holes of said first member to said through passages of said second member, so that any chips formed may pass to the side of said second member remote from said first member via said holes, said channel members and said through passages.
Claim 5
Dependent Claim
56 words
channel members structurally connecting said first and second members and forming passages from said holes of said first member to said through passages of said second member, so that any chips formed may pass to the side of said second member remote from said first member via said holes, said channel members and said through passages.
Claim 6
Dependent Claim
65 words
