Multipurpose cutting means
First Claim
1. A multipurpose cutting means comprising:
- an essentially planar extended support for cutting blades having a first side, a second side, a center and extremities, means near said center for mounting said extended support to a rotary power means for rotating said extended support about an axis of rotation that is essentially perpendicular to the plane of said extended support and that passes through said center, for rotation about said center;
first cutting blades attached to said extremities of said extended support, each said first cutting blade protruding outwardly at an angle from said first side so that mounting said extended support to a rotary power means on said second side provides a first cutting action by said first cutting blades when said extended support is rotated about said axis of rotation and moved parallel to its plane of rotation and that of the material being cut;
second cutting blades attached to the extremities of said extended support, each, said second cutting blade including a first and a second section, said first section of said second cutting blade protruding outwardly at an angle from said second side, said second section of said second cutting blade protruding outwardly at an angle from said first section and away from said extended support center and said axis of rotation such that said second section is essentially parallel to said extended support second side, said second section being an integral continuation of said first section such that mounting said extended support to said rotary power means on said first side provides a second different cutting action by said second cutting blades when said extended support is rotated about said axis of rotation and moved parallel to its plane of rotation and that of the material being cut, and such that mounting said extended support to said rotary power means on either said first side or said second side and rotating it provides a still further and different cutting action by said first and said second cutting blades when said extended support is moved at an angle that is not parallel to either the plane of rotation of said extended support or the surface of the material being cut.

Abstract
A multipurpose cutting device for use with power drives is disclosed. Specific and different blade configurations are provided on opposite sides of an elongated bar or a disk type support for performing different cutting functions. By securing one side of the elongated bar or disk to the end of a shaft, one function can be performed. By securing the other opposite side of the elongated bar or disk to the shaft a different function can be performed. By securing or using the elongated bar or disk at an angle to the material being cut both blade configurations can be used simultaneously to perform yet another function. The blades on the one side and the blades on the other side of the elongated bar or disk may each have the blade configuration facing in one direction of rotation of one shape and the configuration facing in the other direction of another shape for different cutting characteristics when the direction of rotation is reversed.
