  • Patent number: 4967630
    Abstract: A tooth main body defines open ended, crosswise recesses in which cutter elements of lesser width are secured. The cutter elements may be laterally offset from one another and a medial plane of the tooth body for the formation of parallel grooves along a wood panel or other article. Those areas of the recesses not occupied by the cutter elements form gullets into which severed material may pass. The tooth is formed from plate stock to assure uniform tooth thickness which contributes to chain life.
