Abstract
Abstract A lumber cutting and sorting method wherein the lumber is cut into various predetermined lengths by abutting them against gage stops while making the cut. The gage stops have associated sensing means controlling downstream lateral deflector means for sorting the lumber by thickness, width, and/or grade. Crossed plural conveyors remove the cut lumber after sorting.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
28 words
A method of sorting lumber comprising: processing the lumber, sensing a dimension of the lumber while processing the same, and sorting the lumber according to the dimension sensed.
Claim 2
Independent Claim
28 words
A method of sorting lumber comprising: processing the lumber, sensing a dimension of the lumber while processing the same, and sorting the lumber according to the dimension sensed.
Claim 3
Independent Claim
68 words
A method of sorting lumber comprising: determining a dimension of the lumber when the lumber is located where cut, movinG the cut lumber along conveyor means, and transferring the lumber from the conveyor at selected positions therealong in accordance with the determined dimension of the lumber, the location at which the lumber is transferred from the conveyor means being established at the time the lumber dimension is determined.
Claim 4
Independent Claim
68 words
A method of sorting lumber comprising: determining a dimension of the lumber when the lumber is located where cut, movinG the cut lumber along conveyor means, and transferring the lumber from the conveyor at selected positions therealong in accordance with the determined dimension of the lumber, the location at which the lumber is transferred from the conveyor means being established at the time the lumber dimension is determined.
Claim 5
Dependent Claim
21 words
The method of sorting lumber as recited in claim 2, wherein a determined dimension of the lumber is the length thereof.
Claim 6
Dependent Claim
21 words
The method of sorting lumber as recited in claim 2, wherein a determined dimension of the lumber is the width thereof.
Claim 7
Dependent Claim
21 words
The method of sorting lumber as recited in claim 2, wherein a determined dimension of the lumber is the thickness thereof.
Claim 8
Dependent Claim
23 words
The method of sorting lumber as recited in claim 2, wherein determined dimensions of the lumber include the thickness, width and length thereof.
Claim 9
Dependent Claim
25 words
The method of sorting lumber as recited in claim 2, including dropping the lumber which is transferred from the conveyor means into accumulators in stacks.
Claim 10
Dependent Claim
44 words
The method of sorting lumber as recited in claim 2, wherein the lumber is moved at high speed by the conveyor means and is transferred from the conveyor by deflection off selectively operated deflectors movable between operative and inoperative positions over the conveyor means.
Claim 11
Dependent Claim
35 words
The method of sorting lumber as recited in claim 8, which includes changing both the direction of travel and orientation of the lumber substantially the same amounts when deflecting the lumber from the conveyor means.
Claim 12
Independent Claim
76 words
A method of sorting lumber according to length comprising: butting one end of a board to be cut against any one of a plurality of stop members, cutting the board to length as determined by the position of a stop member against which the end of the board is butted, sensing against which stop member the board is butted when cut, and sorting the cut lumber according to the sensed position when the board is cut.
Claim 13
Independent Claim
76 words
A method of sorting lumber according to length comprising: butting one end of a board to be cut against any one of a plurality of stop members, cutting the board to length as determined by the position of a stop member against which the end of the board is butted, sensing against which stop member the board is butted when cut, and sorting the cut lumber according to the sensed position when the board is cut.
