Distorted Saw Patents (Class 144/239)
  • Patent number: 5558142
    Abstract: To provide a reliable, yet resilient, seat for a cutter blade or knife (13) in a rotary milling body (11), the milling body is formed with a bore (21) which intersects the inner wall (19) of a recess (12) in the circumference of the milling body (11). A roll pin is inserted in the bore, retained therein, but projecting over the plane of the wall surface (19). The knife (13) is formed with a longitudinal groove (27), having opposite flat angled side walls (60), which fit around the projecting surface of the roll pin. A holding element (15), fitted into the recess, bears against knife and resiliently clamps it against the roll pin. Preferably, the holding element (15) and the knife (13) are formed with an interengaging projection (41) and recess (42) arrangement.

  • Patent number: 5316061
    Abstract: Dado shims that are disks of substantially incompressible, flexible, color coded plastic sheet material of uniform predetermined thicknesses having a central arbor hole and a radial slot narrower in width than the arbor hole diameter so that each shim is shaped like the letter "C" and can be distorted slightly during positioning on a saw arbor between dado set blades without removing any of the blades, by slipping the shim over the arbor through the slot until the shim seats on the arbor within the shim arbor hole.
