Abstract
A saw tooth of truncated rectangular pyramidal configuration, affixed at its smaller base to a saw body; the larger base, facing the work, is of concave configuration in the longitudinal direction, the direction of cutting movement; further, either the end surfaces of the tooth or the larger base surface of the tooth are concave in the transverse direction, affording four cutting points at the corners of the larger base.
Claims9
A reversible self-sharpening saw tooth of truncated rectangular pyramidal configuration, with the smaller base adapted to be mounted on a carrier with the larger base facing outwardly of the carrier,
- the outwardly facing surface of the larger base of the saw tooth being of concave configuration in a longitudinal direction corresponding to the direction of movement of the saw tooth in a cutting operation,
- and at least one surface of the saw tooth being of concave configuration in a transverse direction so that the saw tooth affords four distinct cutting points located at the corners of the larger base, which four cutting points are maintained throughout substantial wear on the saw tooth.
A reversible self-sharpening saw comprising:
- a carrier having a plurality of saw teeth mounted thereon,
- each saw tooth being of truncated rectangular pyramidal configuration with the smaller base affixed to the carrier and the larger base facing outwardly of the carrier,
- the outwardly facing surface of the larger base of each saw tooth being of concave configuration in a longitudinal direction corresponding to the direction of movement of the carrier in a cutting operation,
- and at least one surface of each saw tooth being of concave configuration in a transverse direction so that the saw tooth affords four distinct cutting points located at the corners of the larger base, which four cutting points are maintained throughout substantial wear on the saw tooth.
