Abstract
A debarking device comprising a debarking arm with a debarking tool mounted to the end thereof. The debarking tool has a curved bearing surface and the debarking arm is provided with a curved recessed seat for receiving the debarking tool. The bearing surface of the debarking tool and the recessed seat of the arm are provided with guides for allowing guided adjustments in the orientation of the debarking tool relative to the debarking arm. Further, the debarking device includes a fastener for retaining and locking the debarking tool at a desired adjusted orientation with respect to the arm.
Claims31
A debarking device comprising:
- a debarking tool and a debarking arm, said debarking arm being adapted to receive said debarking tool, said debarking tool having a curved bearing surface and said debarking arm being provided with a recessed seat for receiving said debarking tool, said recessed seat having substantially the same radius of curvature as said bearing surface;
- guide means provided in the bearing surface of said debarking tool and in said recessed seat of said debarking arm whereby the debarking tool can be located in different positions relative to said recessed seat, and
- means for fixing said debarking tool to the recessed seat of said debarking arm,
- wherein said guide means comprises a ridge means and a groove means which are provided in the bearing surface of said debarking tool and in the recessed seat of said debarking arm,
- wherein the ridge means extends from the peripheral surface of the debarking tool and said groove means comprises at least one groove provided in said curved surface of the recessed seat,
- wherein said curved bearing surface and said recessed seat are spherical, and said groove means comprises a plurality of intersecting grooves which radially extend across said recessed surface.
A debarking device comprising:
- a debarking tool and a debarking arm, said debarking arm being adapted to receive said debarking tool, said debarking tool having a curved bearing surface and said debarking arm being provided with a recessed seat for receiving said debarking tool, said recessed seat having substantially the same radius of curvature as said bearing surface;
- guide means provided in the bearing surface of said debarking tool and in said recessed seat of said debarking arm whereby the debarking tool can be located in different positions relative to said recessed seat, and
- means for fixing said debarking tool to the recessed seat of said debarking arm,
- wherein said guide means comprises a ridge means and a groove means which are provided in the bearing surface of said debarking tool and in the recessed seat of said debarking arm,
- wherein said ridge means extends from the peripheral surface of the debarking tool and said groove means comprises at least one groove provided in said curved surface of the recessed seat,
- wherein said curved bearing surface and said recessed seat are cylindrical,
- a plurality of indentations positioned along said ridge means, and
- a knob means located in said groove means and extending from the bottom thereof to selectively engage one of said plurality of indentations.
A debarking arm for use in a debarking machine, said arm having at its free end a recessed seat for receiving a debarking tool, said seat having the shape of a portion of a surface of revolution,
- wherein said surface of revolution is a concave shaped surface,
- wherein said seat has guide means for guide setting of said tool in a direction along the periphery of said surface of revolution, and
- wherein said guide means includes a plurality of intersecting grooves extending along the periphery of said surface of revolution.
A debarking arm for use in a debarking machine, said arm having at its free end a recessed seat for receiving a debarking tool, said seat having the shape of a portion of a surface of revolution,
- wherein said surface of revolution is a cylindrical surface,
- wherein said recessed seat has guide means for guide setting of said tool in a direction along the periphery of said surface of revolution,
- wherein said guide means include at least one groove extending along the periphery of said surface of revolution, and
- including indexing means for fixing said tool in predetermined setting positions, said indexing means comprising a protrusion located in said groove.
A debarking arm for use in a debarking machine, said arm having at its free end a recessed seat for receiving a debarking tool, said seat having the shape of a portion of a surface of revolution,
- wherein said surface of revolution is a cylindrical surface,
- wherein said seat has guide means for guide setting of said tool in a direction along the periphery of said surface of revolution,
- wherein said guide means includes a plurality of intersecting rows of indentations.
A debarking device comprising:
- a debarking arm provided with a curved recessed seat;
- a debarking tool, provided with a cutting edge, having a curved bearing surface rotatably disposed within said recessed seat of said arm, said bearing surface being provided with a plurality of indentations;
- means for retaining said tool within said curved recessed seat of said arm and for locking said tool in position with respect to said arm;
- and
- a protrusion extending from said recessed seat of said arm for cooperating with one of said indentations of said tool for setting said tool orientation with respect to said arm.
A debarking device comprising:
- a debarking arm provided with a concave shaped recessed seat;
- a debarking tool, provided with a cutting edge, having a convex shaped bearing surface adjustably disposed within said recessed seat of said arm;
- and
- means of retaining said tool within said recessed seat of said arm and for locking said tool in position with respect to said arm.
A debarking device comprising:
- a debarking arm provided with a curved recessed seat, said curved recessed seat provided with a plurality of indentations;
- a debarking tool, provided with a cutting edge, having a curved bearing surface rotatably disposed within said recessed seat of said arm;
- means for retaining said tool within said curved recessed seat of said arm and for locking said tool in position with respect to said arm;
- and
- at least one protrusion extending from said curved bearing surface of said tool for cooperating with at least one of said indentations in said curved recessed seat of said arm for setting said tool orientation with respect to said arm.
