Abstract
1,075,806. Sawing. HEINEMANN SAW CORPORATION. April 12, 1965, No. 15526/65. Heading B5L. A circular saw comprises a metal disc having cutting teeth 14 at the periphery thereof at widely spaced arcuate locations, and a multiplicity of fan-like projections 16 on the peripheral regions of the disc intermediate the cutting teeth, the lateral sides of the projections lying entirely within the parallel cutting planes of the teeth which define the lateral sides of a kerf in a workpiece and the outermost extremities of the projections being offset radially inward from the outermost extremities of the cutting teeth which define the bottom of the kerf, the projections being proportional to direct a stream of ambient air through the kerf between the passage of successive teeth without contacting the workpiece. The saw may be used for cutting thermoplastic or thermosetting material. The cutting teeth may consist of tungsten-carbide inserts and are spaced apart by distances approximately equal to the length of the radius of the saw with 5 to 15 projections between the adjacent teeth. In manufacture the periphery of the disc may be rough milled into a toothed profile and certain of the rough teeth are provided with the carbide teeth or other form of edged cutting teeth, the remaining teeth being left to provide the fan-like projections for cooling the material during sawing.
