Abstract From the Canadian patent

A stabilizing mechanism for the circular saw of a felling head is provided. The mechanism includes at least one gyroscopic stop disposed slightly above the saw on one of its sides in order to prevent the tilting of the saw in the opposite direction due to the gyroscopic effect when the saw is angled forward. Gyroscopic stops may be provided on each side of the saw and be combined with back stops extending over the rear extremity of the saw.

Why it's free to use

  • Filed June 2, 2005 and granted April 10, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 2, 2025.
  • Certificates of supplementary protection extend only drug patents, and it isn't classified as one.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
