Abstract
A cutting tooth for a tree felling saw having a concave front surface and a convex rear surface can be removably fixed to a saw by a fastening device The front surface and the rear surface are uniformly spaced and have a plurality of side surfaces extending therebetween. The intersection of each side section with the front surface forms a cutting edge. An aperture is formed in the cutting tooth for receiving the mounting element.
Claims14
A cutting tooth for removable attachment to a saw comprising:
- a concave front surface;
- a convex rear surface uniformly spaced form said front surface, the curvature of said rear surface corresponding with the curvature of said front surface to define a tooth having a uniform thickness;
- and
- a plurality of side surfaces, each side surface extending form the front surface to the rear surface,
- the intersection of each of the side surfaces with the front surface defining a cutting edge,
- the cutting tooth defines an aperture extending from the front surface to the rear surface for receiving a fastening device to removably attach the tooth to the cutting device.
A cutting tooth assembly for removably attaching a replaceable tooth to a tooth mount of a tree cutting device:
- a cutting tooth having a concave front surface, a convex rear surface, and a plurality of side surfaces connecting the front and rear surfaces, the curvature of the front surface corresponding with the curvature of the rear surface to define a cutting tooth having a uniform thickness, the cutting tooth defining a centrally located aperture which extends through the tooth from the front surface to the rear surface;
- and
- a fastening device removably received in the aperture for removably attaching the cutting tooth to the tooth mount of the tree cutting device.
A cutting tooth assembly for a saw comprising;
- a tooth mount attached to the saw, the tooth mount being provided with a recessed seat and defining a bore originating at the seat;
- an adapter having a first end being concave in shape and a second end configured to be received by the sea, the adapter defining an aperture extending from the first end to the second end;
- a cutting tooth having a concave front surface and a convex rear surface, the curvature of the front surface corresponding with the curvature of the rear surface to define a cutting tooth in which the distance between the front surface and the rear surface is uniform, the cutting tooth defining an aperture extending form the front surface to the rear surface, the cutting tooth being positioned adjacent the adapter with the rear surface being received by the first end;
- and
- a fastening device extending through the aperture in the cutting tooth, through the aperture in the adapter, and into the bore of the tooth mount to removably attach the cutting tooth to the saw.
