Abstract

1,137,275. Sawing. G. A. WOODS. 9 Dec., 1966 [10 Dec., 1965], No. 52585/65. Heading B5L. A circular saw blade for cutting and simultaneously planing wood comprises at least one cutting bit 2 mounted at a positive cutting angle and at least one separate planing bit 3 mounted at a negative cutting angle, the or each planing bit being mounted with its outermost tip positioned within the circle described by the outermost tip of the cutting bit or bits and with its planing edge or edges projecting from the side or sides of the blade further than the cutting bit or bits. The blade consists of a disc 1 having cutting bits 2 alternating with planing bits 3. The cutting bits have a positive cutting angle a between 30 and 40 degrees and a clearance angle b of 10 to 15 degrees. The planing bits are set at a negative angle c to the radius of the blade of 20 to 45 degrees. The planing edges may be straight or slightly curved and have rounded ends, and have a cutting angle of 15 to 30 degrees and a clearance angle of 2 to 15 degrees. The planing bits may have one cutting edge each or be hollow ground so as to cut on both sides of the blade. The cutting bits may project 0.0125 in. from the sides of the disc and the planing edges 0.025 in. The cutting bits may project 0.050 in. radially beyond the planing bits. The blade may be used in a foursided planing and moulding machine having a riving knife thicker than the blade.
