  • Depth gauge for a cutter
    Patent number: 5974933
    Abstract: A depth gauge leading the cutting edge in a cutter device has a body portion disposed in a substantially upright plane. The depth gauge includes a top plate portion cantilevered laterally over the body. A juncture section joins the depth gauge plate portion to the body of the cutter and is deformed intermediate its front and rear ends to strengthen the depth gauge against breakage.

  • Cutter with bent over depth gauge
    Patent number: 5740715
    Abstract: A cutter for an endless cutter device having a body portion disposed in a substantially upright plane, a cutter portion on a rearward region of the body and a depth gauge portion on a forward region of the body. The depth gauge has a downwardly sloping planar upper surface with a multi-angular configuration. A rear edge of the depth gauge has a central portion which is highest and farthest to the rear, with side portions extending forwardly and downwardly therefrom in diverging directions. A free outer edge intermediate the rear edge and forward edge of the depth gauge is the maximum width portion of the depth gauge. Converging edges progress forwardly from the maximum width portion to the front edge of the depth gauge. The heel of the body portion is clipped to permit limited rearward rocking of the cutter.
