Abstract
This device consists primarily of a tool (blade, chisel, or sanding attachment) which is attached to a tool holder. The tool holder in turn is attached by a bearing to a shaft which passes thru a flywheel, the shaft is offset from the center of the flywheel thereby causing an eccentric rotation of the tool holder. The flywheel and tool holder "float" as an assembly on rubber couplings and impart to the tool components of these various motions slicing, chopping, scraping, and rubbing.
Claims5
A surface preparation machine for removing material adhered to a planar surface, the machine comprising:
- a wheeled frame having an upper portion and lower portion;
- a motor mounted to the upper portion of said frame;
- a vertical shaft attached at one end to said motor and extending downwardly therefrom;
- an annular shaped flywheel attached to said shaft, said shaft offset from the center of said flywheel and extending therethrough;
- a horizontal base plate attached to the lower portion of said frame, said base plate having an aperture therein for receiving said shaft therethrough;
- a horizontal tool holding plate disposed below said base plate and parallel thereto, the other end of said shaft attached to said tool holding plate, said plate having a tool mounted thereon for removing the material;
- and
- coupling means for attaching said plate to said base plate and suspending said plate therefrom;
- said motor rotating said flywheel and said shaft, said shaft providing an eccentric motion in providing an orbital movement of said tool holding plate in a horizontal plane.
