Apparatus for sharpening saw blades

An apparatus for sharpening a cutting means including a sharpening head mounted on a pivot arm, said arm being mounted for pivotal movement about an axis transverse to the apparatus and the cutting means, the head being pivotally mounted to the arm allowing for co-ordinated oscillation of the head from side to side about an axis transverse to the arm, the oscillation of the head being controlled by an actuating rod extending parallel to the arm, one end of the rod being pivotally attached to the head and the rod being reciprocated in a direction extending along the rod by a control cam spaced from the head, the oscillation of the head enabling teeth on the cutting means to bevelled in various directions, the position of the pivot axis of the arm being adjustable to suit a variety of hook angles of teeth of the cutting means.
