Embodiment Construction

[0018] For a better understanding of the invention and its method of operation, turning now to the drawings, FIG. 1 illustrates preferred cutter blade sharpener 10 having frame 11 preferably formed from tubular steel. Frame 11 includes front legs 12, 12' and rear legs 13, 13'. Rigidly positioned on tubular frame 11 is shelf 14 to which slide table 15 is mounted. Slide table 15 is preferably a conventional compound or bi-directional milling table as sold by Enco Manufacturing of 135 South LaSalle, Chicago, Ill. 60674. Other manufacturers of such slide tables include Penn Tool Company, 1776 Springfield Avenue, Maplewood, N.J. 07040. Slide table 15 is mounted to shelf 14 as by bolts 16 (only one shown in FIG. 1) and includes table base 17 and table top 18. Table base 17 is movable laterally on frame 11 by turning crank handle 19 whereas table top 18 is movable longitudinally on frame 11 by turning crank handle 20 as seen by the arrows in FIG. 2. As would be understood, table base 17 an...

Abstract

A cutter blade sharpener and method allows for quick, easy and uniform sharpening of tree felling head circular cutters. Each cutter blade is individually removed from the circular cutter and is positioned on the sharpener, one at a time whereby the cutter blades are then ground in uniform fashion. The sharpener includes a tubular frame having a slide table mounted thereon for both lateral and longitudinal movement of the cutter blade proximate the grinding wheel.

Description

[0001] The invention herein pertains to blade sharpeners and particularly for sharpeners for cutter blades as are used with tree felling heads.DESCRIPTION OF THE PRIOR ART AND OBJECTIVES OF THE INVENTION[0002] Many standard tree felling heads utilize circular cutters which turn at high rates of speed for felling trees. Such circular cutters commonly have eighteen cutter blades, each with four cutting edges located along the periphery of the circular cutter. The cutter blades regularly wear, sometimes in an uneven fashion and must be removed and discarded. The standard practice is to remove the blades from the circular cutter and replace them with new cutter blades.[0003] With recent increased costs of labor and equipment in the tree harvesting industry, maintenance of circular cutters having a plurality of cutter blades are a source of concern. It is not prudent to use a circular cutter until it is completely worn and then discard it. Also, it is now not prudent or economical to han...
