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: 5
Claim 1
Independent Claim
69 words
A system for cutting and sorting lumber comprising: a. a plurality of primary conveyors each having an upstream lumber cutting means for cutting the lumber into selected dimensions; b. a plurality of secondary conveyors crossing below said primary conveyors; and c. sorting means associated with each primary conveyor for transferring therefrom the cut lumber having a particular set of dimensional characteristics, such transfer being to a single secondary conveyor.
Claim 2
Independent Claim
69 words
A system for cutting and sorting lumber comprising: a. a plurality of primary conveyors each having an upstream lumber cutting means for cutting the lumber into selected dimensions; b. a plurality of secondary conveyors crossing below said primary conveyors; and c. sorting means associated with each primary conveyor for transferring therefrom the cut lumber having a particular set of dimensional characteristics, such transfer being to a single secondary conveyor.
Claim 3
Dependent Claim
86 words
Lumber sorting apparatus comprising: a. primary conveying means for conveying the lumber lengthwise along a predetermined path; and b. a plurality of deflecting means spaced along said path and selectively movable into said path; said deflecting means each having a surface inclined with respect to said path for urging the forward end of the lumber substantially horizontally and laterally out of said path and moving the lumber off said primary conveying means with its length oriented at a substantial angle with respect to said predetermined path.
Claim 4
Dependent Claim
86 words
Lumber sorting apparatus comprising: a. primary conveying means for conveying the lumber lengthwise along a predetermined path; and b. a plurality of deflecting means spaced along said path and selectively movable into said path; said deflecting means each having a surface inclined with respect to said path for urging the forward end of the lumber substantially horizontally and laterally out of said path and moving the lumber off said primary conveying means with its length oriented at a substantial angle with respect to said predetermined path.
Claim 5
Dependent Claim
31 words
The lumber sorting apparatus defined by claim 2, wherein said deflecting means includes a curved, substantially vertical plate positioned above said primary conveying means and movable downwardly to intersect said path.
