Abstract
A wood chipping or cutting knife assembly providing improved knife stability. A number of control surfaces and other geometric features are provided to stabilize the knife in the assembly. An improved splitter is also provided for the knife assembly.
Claims (10)
1. A wood cutting apparatus, comprising:
a rotating member for rotating about an axis of rotation;
a knife having a cutting edge;
a counterknife for mounting said knife to said rotating member, said counterknife having a way disposed below said cutting edge and accessible from outside the appara-tus; and a splitter adapted for manual insertion and removal through said way, said splitter having at least one splitting portion including a curvilinear splitting edge for splitting articles of wood cut by the knife.
a rotating member for rotating about an axis of rotation;
a knife having a cutting edge;
a counterknife for mounting said knife to said rotating member, said counterknife having a way disposed below said cutting edge and accessible from outside the appara-tus; and a splitter adapted for manual insertion and removal through said way, said splitter having at least one splitting portion including a curvilinear splitting edge for splitting articles of wood cut by the knife.
2. The apparatus of claim 1, wherein said splitting edge is convex.
3. The apparatus of claim 1, wherein said splitter includes two splitting portions having a curvilinear splitting edge, said two splitting edges being substantially symmetric about an axis of said splitter.
4. The apparatus of claim 2, wherein said splitter includes two splitting portions having a curvilinear splitting edge, said two splitting edges being substantially symmetric about an axis of said splitter.
5. A wood cutting apparatus, comprising:
a rotating member for rotating about an axis of rotation;
a knife having a cutting edge;
a counterknife for mounting said knife to said rotating member, said counterknife having a way disposed below said cutting edge and accessible from outside the appara-tus; and a splitter adapted for manual insertion and removal through said way, said splitter having two splitting edges substantially symmetrically disposed about an axis of said splitter.
a rotating member for rotating about an axis of rotation;
a knife having a cutting edge;
a counterknife for mounting said knife to said rotating member, said counterknife having a way disposed below said cutting edge and accessible from outside the appara-tus; and a splitter adapted for manual insertion and removal through said way, said splitter having two splitting edges substantially symmetrically disposed about an axis of said splitter.
6. A splitter for a knife assembly for a wood cutting apparatus, the knife assembly including a knife having a cutting edge and a counterknife for mounting the knife to the apparatus, the counterknife having a way, the splitter adapted to fit in said way and comprising two substantially symmetrically disposed splitting edges adapted for splitting articles of wood cut by the knife.
7. The splitter of claim 6, wherein said splitting edges are curvilinear.
8. The splitter of claim 7, wherein said splitting edges are convex.
9. A splitter for a knife assembly for a wood cutting apparatus, the knife assembly including a knife having a cutting edge and a counterknife for mounting the knife to the apparatus, the counterknife having a way, the splitter adapted to fit in said way and comprising at least one curvilinear splitting edge adapted for splitting articles of wood cut by the knife.
10. The splitter of claim 9, wherein said at least one splitting edge is convex.
