Edge buster series round blade sharpener and the edge tracker sharpener

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...

Benefits of technology

[0020] Usually 4-5 turns per side are sufficient. As the crank handle turns the diamond file located on the pivot arm slide reciprocates 3 times per single blade revolution. The diamond file is also pivoting on its on axis as the blade is turning and file is reciprocating. This motion combined with the proper tension produces an extremely sharp edge while only removing microscopic amounts of material from the blade edge itself. (This allows us to achieve one of our design goals of greatly extending the life of the blade. We are sharpening the blade instead of grinding the blade which allows us to achieve another design goal of creating a durable edge that is sharper than an actual new blade from the manufacturer, the manual operation and low rpm's allow us to achieve still another design goal of not heating the blade and destroying the temper of the blade.) Once the blades edge is sharpened locate the contoured safety handle and lift the pivot arm assembly back to the vertical position until you hear it click indicating its position is secure. (Always remember to count the number of revolutions per side a black dry erase pen is provided to mark the blade for aiding in counting these revolutions).
