Claims
- 1. An apparatus for cutting logs, comprising:a) a plurality of cutting blades, said blades being rotatable; b) a frame for supporting said plurality of cutting blades; c) a means for conveying the logs to said plurality of cutting blades; d) a means for conveying the logs away from said plurality of cutting blades; e) a plurality of arms having one each of said cutting blades disposed thereon; f) means for moving said plurality of arms between an upward position or a downward position; g) means for rotatably mounting said cutting blades on said arm; and h) at least one drive shaft for rotatably driving said plurality of cutting blades in both of said upward and downward positions, such that at least one of said rotating blades may be moved by said arm to the downward position and continue rotating so as to cut the logs while the remaining of said cutting blades continue rotating in said upward position.
- 2. The apparatus of claim 1, wherein said cutting blades are disposed in the vertical plane being generally perpendicular to the centerline of the logs.
- 3. The apparatus of claim 1, wherein said frame further comprises a cross member upon which said cutting blades are disposed and a pair of leg members for supporting said cross member.
- 4. The apparatus of claim 1, wherein said means for conveying the logs to said plurality of cutting blades further comprises a first lifter arm that raises the logs toward said cutting blades, and, a second anti-pinch arm which cooperates with said first lifter arm to hold the log thereinbetween for cutting by said cutting blades.
- 5. The apparatus of claim 1, wherein said means for moving said plurality of arms upward or downward further comprises a hydraulic cylinder having a first end connected to said arm and a second end connected to said frame.
- 6. The apparatus of claim 1, further comprising a pulley disposed on a first end of said arm and a chain connected between said pulley and said drive shaft disposed on a second end of said arm.
- 7. The apparatus of claim 6, further comprising means for adjusting the tension of said chain.
- 8. The apparatus of claim 1, further comprising a means for rotatably driving said drive shaft so that said cutting blade rotates.
- 9. The apparatus of claim 8, further comprising one or more belts for rotating said drive shaft, said belts having a first end connecting to said drive shaft, and a second end connecting to a motor means.
- 10. The apparatus of claim 1, further comprising a means for controlling said cutting blades whereby a log contour is developed which yields a log sawing solution for the most efficient utilization of the logs.
- 11. The apparatus of claim 10, wherein said means for controlling said cutting blades further comprises a plurality of lasers, said lasers being utilized to develop a log contour so that a sawing solution is developed.
- 12. The apparatus of claim 11, further comprising a means for a computer to control said cutting blade and develop said sawing solution.
