Abstract
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. Also, the blades can be made to mount directly onto a saw arbor with spacer washers taking the place of the cam assembly. For industrial applications, more than three blade configurations are envisioned…
