Patent number: 5564324Abstract: A variable thickness linear saw design is proposed for enabling maximum reduction of the thickness of the kerf associated with such saws. Typically, such saws have cutting teeth mounted on the leading edge of a supporting plate. In the improvement of this saw, this supporting plate is given two discrete thicknesses relative to the kerf. A first and narrow thickness (relative to the kerf) longitudinal segment is used parallel to and adjacent the supported teeth. This first and narrow thickness longitudinally extending segment only occupies a fraction of less than half and preferably about 20% of the full width of the saw behind the supported teeth. A second and expanded thickness (relative to the kerf) longitudinal segment is used for the remaining width of the saw. The reduced thickness of the narrow tooth supporting section of the saw forms in the case of the linear saws a preferred exit path for sawdust, this preferred exit path being immediately adjacent and behind the supported teeth of the saw.Type: GrantFiled: April 1, 1994Date of Patent: October 15, 1996Assignee: California Saw and Knife WorksInventor: Warren M.

Multiple saw blade adjustable dado cutter assembly including a cam assembly and nestable dado blades
Patent number: 5309962Abstract: A multiple saw blade adjustable dado cutter assembly. The cutter can be used with a table saw or a radial arm saw, for example, to make dado cuts in board lumber. A pair of cooperating cams, each connected to a saw blade, can be adjusted to make a dado cut of a desired width. If the desired dado width is wider than the two blade configuration can cut, a center cam attached to another blade can be inserted between the pair of cooperating cams. With the three blade configuration, the three cams cooperate to allow the three blades to be spaced for the desired width of cut. In both configurations and at any spacing width, the two or three blades employed remain in a generally parallel alignment and transverse to the axis of the arbor on which the assembly is secured. To permit the blades to function with this geometrical relationship and to be adjustable, not all of the blade teeth lie in the same plane. The sequentially operating three or more cam assembly has uses beyond dado cutting.Type: GrantFiled: May 13, 1993Date of Patent: May 10, 1994Assignee: Vermont American CorporationInventors: Wilfred M.
