Benefits of technology

The present invention provides a blade sharpening, grinding, and sizing apparatus that can be used manually or with a power source. The apparatus includes a crank handle, a diamond file, and a pivot arm mounting bracket. The apparatus also includes an angle adjustment rail and a blade adjustment slide for setting the proper blade diameter and achieving a sharp edge. The apparatus allows for easy and safe sharpening of blades without heating them or damaging their temper. The invention also includes a contoured safety handle for safely lifting the pivot arm assembly. The round blade sharpener can be used with a small blade adaptor assembly for smooth edge sharpening.

Abstract

Apparatus for sharpening, grinding or sizing a cutting edge on a circular blade which has dulled, chipped, or needs re-sizing blades from 2½″ to 48″ diameter. Differs from prior art in that it sharpens, grinds or sizes circular blades and blades with different geometrical shaped blades. Manually or pneumatically externally powered driven. Furthermore, it is necessary to maintain factory blade edge angles when sharpening the edge of the blade allowing the blade life to be greatly extended and maintain a like new cutting edge through out the life of the circular blade. Present invention is also unique in respect to the not heating up of the blade edge using similar devices. The simplest and safest sharpener of its type to operate. Also the Pneumatically Driven Machine incorporates such a design as to sharpen blades which are of different geometric shapes I.e. Scalloped, Wide Slotted

Description

BACKGROUND OF THE INVENTION [0001] (1) Field of the Invention [0002] The present invention relates to an improved Round Blade Sharpener apparatus for sharpening, grinding and or sizing a cutting edge on a circular blade which has dulled, chipped, or needs to be re-sized to a specific out side diameter. Present invention differs from prior art in that it sharpens, grinds, and re-sizes where prior art grinds to sharpen. Present invention differs from prior art in that it sharpens, grinds or sizes circular blades, blades with different geometrical edge profiles and blades diameter from 2½″ to 48″. Present invention may be manually driven or driven by other externally powered drive apparatuses and not limited to a pneumatic drive as will be described in this application for patent. Present invention differs from prior art in that we use Flexible Drive Cables. [0003] After extended use in a plant, shop or any high volume cutting facility it becomes necessary to grind small indented or ch...
