Abstract

A cutter for an endless cutter device having a body portion disposed in a substantially upright plane, a cutter portion on a rearward region of the body and a depth gauge portion on a forward region of the body. The depth gauge has a downwardly sloping planar upper surface with a multi-angular configuration. A rear edge of the depth gauge has a central portion which is highest and farther to the rear, with side portions extending forwardly and downwardly therefrom in diverging directions. A free outer edge intermediate the rear edge and forward edge of the depth gauge is the maximum width portion of the depth gauge. Converging edges progress forwardly from the maximum width portion to the front edge of the depth gauge. The heel of the body portion is clipped to permit limited rearward rocking of the cutter.

Dependent claims

A cutting chain comprising a plurality of pivotally interconnnected links including cutter links, with a cutter link in said chain in an upright position comprising,

a body portion disposed in a substantially upright plane and having forward and rearward regions,
a cutter portion on the rearward region of the body portion having a forwardly facing cutting edge at a selected elevation above the body portion, and
a depth gauge portion on the forward region of the body portion, said depth gauge portion comprising a plate portion bent over at substantially a right angle relative to the plane of the body portion and having an upper surface inclined substantially continuously downwardly from a rearwardly facing rear edge of the plate portion which is disposed at an elevation adjacent but below the elevation of the cutting edge to a forwardly facing front edge of the plate portion which is disposed at a lower elevation, said depth gauge portion being substantially pentagonal with one side of said pentagonal configuration forming a front edge for the depth gauge, and said rear edge having a central portion nearest said cutting edge and a pair of side portions opposite said front edge which extend forwardly from said central portion and diverge from each other on extending forwardly.
