Claims
- 1. A wallpaper scarifying device for scarifying wallpaper on a surface comprising:
- a plate;
- at least one scarifying assembly, the at least one scarifying assembly including a swivel fixture rotatably coupled to the plate and rotatably carrying a cutting disk offset from an axis of rotation of the swivel fixture, the cutting disk having a plurality of teeth extending from a periphery thereof; and
- the swivel fixture including a shaft having a first end rotatable coupled to the plate about the axis of rotation and a second end, and a base having a first surface coupled to the second end of the shaft and a second surface, the second surface canted at an angle with respect to a plane perpendicular to the axis of rotation and substantially parallel to the surface to be scarified, the cutting wheel coupled to and substantially parallel with the second surface.
- 2. A wallpaper scarifying device as claimed in claim 1 wherein the cutting disk is carried at an angle of less than 45 degrees relative a plane perpendicular to the axis of rotation.
- 3. A wallpaper scarifying device as claimed in claim 1 wherein the angle of the cant is in the range of approximately 20-30 degrees.
- 4. A wallpaper scarifying device as claimed in claim 1 wherein the base is coupled to the shaft at an angle with respect to the plane perpendicular to the axis of rotation.
- 5. A wallpaper scarifying device as claimed in claim 4 wherein the base is coupled to the shaft at an angle of approximately 5 degrees.
- 6. A wallpaper scarifying apparatus as claimed in claim 1 wherein the plate further includes a socket for rotatably receiving the first end of the shaft.
- 7. A wallpaper scarifying device comprising:
- a plate;
- at least one scarifying assembly coupled to the plate, the at least one scarifying assembly including a swivel fixture rotatably coupled to the plate about an axis of rotation and rotatably carrying a cutting disk at an angle of less than 45 degrees relative a plane perpendicular to the axis of rotation, the cutting disk having a plurality of teeth extending from a periphery thereof; and
- the swivel fixture including a shaft having first end rotatable coupled to the plate about the axis of rotation and a second end, and a base having a first surface coupled to the second end of the shaft and a second surface, the second surface canted at an angle less than 45 degrees with respect to a plane perpendicular to the axis of rotation and substantially parallel to the surface to be scarified, the cutting wheel coupled to and substantially parallel with the second surface.
- 8. A wallpaper scarifying device as claimed in claim 7 wherein the angle of the cant is in the range of approximately 20-30 degrees.
- 9. A wallpaper scarifying device as claimed in claim 7 wherein the base has a first end coupled to the second end of the shaft and a second end to which the cutting disk is coupled, offsetting the cutting disk from the axis of rotation of the swivel fixture.
- 10. A wallpaper scarifying device as claimed in claim 9 wherein the base is coupled to the shaft at an angle with respect to the plane perpendicular to the axis of rotation.
- 11. A wallpaper scarifying device as claimed in claim 10 wherein the base is coupled to the shaft at an angle of approximately 5 degrees.
- 12. A wallpaper scarifying apparatus as claimed in claim 7 wherein the plate further includes a socket for rotatably receiving the first end of the shaft.
- 13. A wallpaper scarifying device comprising:
- a body including a plate to be held substantially perpendicular to a surface to be scarified, and a skirt extending substantially perpendicularly from a periphery of the plate; and
- a plurality of scarifying assemblies coupled to the plate, each of the plurality of scarifying assemblies including a swivel fixture having a shaft with a first end rotatably coupled to the plate and rotatable about an axis of rotation and a second end, and a base having a first surface coupled to the second end of the shaft and a second surface, the second surface canted at an angle less than 45 degrees with respect to a plane perpendicular to the axis of rotation and substantially parallel to the surface to be scarified, and a cutting wheel having a plurality of teeth extending from a periphery thereof, rotatably coupled to and substantially parallel with the second surface of the base.
- 14. A wallpaper scarifying device as claimed in claim 12 wherein the base has a first end coupled to the second end of the shaft and a second end to which the cutting disk is coupled, offsetting the cutting disk from the axis of rotation of the swivel fixture.
- 15. A wallpaper scarifying device as claimed in claim 14 wherein the base is coupled to the shaft at an angle with respect to the plane perpendicular to the axis of rotation.
- 16. A wallpaper scarifying device as claimed in claim 14 wherein the base is coupled to the shaft at an angle of approximately 5 degrees.
- 17. A wallpaper scarifying device as claimed in claim 14 wherein the angle of the cant is in the range of approximately 20-30 degrees.
