Abstract
A ripper tooth for use mounted on an excavation tool having a tool body mounted for rotation on an excavation machine arm, the ripper tooth being mounted to the tool body for ripping engagement with a substrate. The ripper tooth has first and at least second portions, each with a tip disposed for ripping engagement with the substrate. The first and second portions are laterally spaced apart generally along the axis of rotation of the tool relative to the arm, and the first and second portions are angularly spaced apart generally in a direction of substrate ripping motion. The first portion is disposed on a first axis and the second portion is disposed on a second axis, the first and second axes being different. Ripper excavation tools with one or more ripper teeth of the disclosure mounted to the tool body are also described.

A ripper tooth for use on an excavation tool comprising a tool body mounted for rotation on an arm of an excavation machine, said ripper tooth being mountable to the tool body for ripping engagement with a substrate and comprising:
- a plurality of ripper tooth portions, each ripper tooth portion with a ripper tooth tip disposed at a forward end thereof for ripping engagement with the substrate;
- each ripper tooth tip being laterally spaced apart from the other ripper tooth tips of the plurality of ripper tooth portions in a general direction along the axis of rotation of said ripper excavation tool relative to the arm,
- each ripper tooth tip being angularly spaced apart from the other ripper tooth tips of the plurality of ripper tooth portions in a general direction of substrate ripping motion, and
- each ripper tooth portion being disposed on a axis different from all other ripper tooth portions of the ripper tooth.
A ripper excavation tool comprising a tool body mounted for rotation from an arm of an excavation machine, said ripper excavation tool further comprising:
- at least two ripper teeth are mounted to the tool body spaced apart along a leading edge of the excavation tool body and disposed for ripping engagement with a substrate, each of said at least two ripper teeth comprising:
- a plurality of ripper tooth portions, each ripper tooth portion with a ripper tooth tip disposed at a forward end thereof for ripping engagement with the substrate,
- each ripper tooth portion being laterally spaced apart from the other ripper tooth tips of the plurality of ripper tooth portions in a general direction along the axis of rotation of said ripper excavation tool relative to the arm, and
- each ripper tooth portion being angularly spaced apart from the other ripper tooth tips of the plurality of ripper tooth portions in a general direction of substrate ripping motion,
- a first ripper tooth portion and a second ripper tooth portion being disposed at predetermined angles from a tangent to an arc of rotation extending generally through said first ripper tooth tip and said second ripper tooth tip with an arc center near an axis of rotation of said excavation tool body, and
- each ripper tooth portion being disposed on an axis different from all other ripper tooth portions of the ripper tooth.
