Abstract

A cutter for use with a comminuting apparatus includes a body, a body slot, and a bore hole. The body has first and second opposing surfaces, a first edge adjoining the first and second surfaces, and a cutting edge opposite the first edge. The body extends from the cutting edge to the first edge. The body slot extends through the cutter body from the first surface to the second surface. The bore hole is enclosed by the first and second surfaces, and extends from the body slot to the first edge.

First claim

What is claimed is:

1. A cutter and fastener for use with a comminuting apparatus, the cutter comprising:
a body having first and second opposing surfaces, a first edge extending from the first surface to the second surface, and a cutting edge opposite the first edge, the cutter body extending from the cutting edge to the first edge;
a body slot extending through the cutter body from the first surface to the second surface; and
a bore hole enclosed by the first and second surfaces, the bore hole extending from the body slot to the first edge;
the fastener extending through the bore hole and into the body slot, a locking nut being coupled to the fastener and being adjacent to the first edge of the cutter to prevent movement of the fastener.

2. The cutter and fastener as set forth in claim 1 , wherein the body slot is oriented in a direction substantially perpendicular to the cutting edge.

3. The cutter and fastener as set forth in claim 1 , wherein the bore hole is threaded.

4. The cutter and fastener as set forth in claim 1 , wherein the body slot includes first and second opposing ends, and the bore hole extends from the second end of the body slot to the first edge.

5. The cutter and fastener as set forth in claim 4 , wherein the first and second ends of the body slot are shaped complementary to an outer peripheral surface of a fastener.

6. The cutter and fastener as set forth in claim 5 wherein the first and second ends the body slot have a generally arcuate shape.

7. A cutter assembly for use with a comminuting apparatus, the assembly comprising:
a cutter including:
a body having first and second opposing surfaces, a first edge extending from the first surface to the second surface, and a cutting edge opposite the first edge, the cutter body extending from the cutting edge to the first edge;
a body slot extending through the cutter body from the first surface to the second surface; and
a bore hole extending within the cutter body from the body slot towards the first edge;

a first fastener extending through the body slot of the cutter and configured to secure the cutter to a rotatable drum; and
a second fastener extending through the bore hole and into the body slot, the second fastener including a first end and a second end, the first end engaging the first fastener.

8. The assembly as set forth in claim 7 , wherein the second fastener is a threaded fastener.

9. The assembly as set forth in claim 7 , further comprising a locking nut coupled to the second fastener, the locking nut configured to prevent movement of the second fastener with respect to the first fastener.

10. The assembly as set forth in claim 9 , wherein the locking nut is coupled adjacent to the first edge of the cutter.

11. The assembly as set forth in claim 7 , wherein the body slot includes first and second opposing ends, and the bore hole extends from the second end of the body slot to the first edge.

12. The assembly as set forth in claim 11 , wherein the first and second ends are shaped complementary to an outer peripheral surface of the first fastener.

13. The assembly as set forth in claim 12 , wherein the first and second ends have a generally arcuate shape.

14. The assembly as set forth in claim 7 in combination with a rotatable drum, wherein the cutting assembly is secured to the rotatable drum via first fasteners.

15. The assembly as set forth in claim 14 , wherein the rotatable drum includes a pocket defined therein, and wherein the cutter assembly is secured within the pocket.

16. The assembly as set forth in claim 15 , wherein the second end of the second fastener abuts the pocket of the rotatable drum.

17. The assembly as set forth in claim 14 wherein the cutter assembly is secured to a mounting block, wherein the mounting block is mounted to the rotatable drum.
