Abstract
A method and apparatus for aiming a tree to be felled including a tool for precisely marking a face notch to be cut into a tree trunk, said tool comprising a main body, an aiming rod on the main body, and two pivoting tree-engaging marking arms mounted pivotably together on the main body for partially encircling the tree trunk and identifying the upper and lower cuts of a generally horizontal portion of a hinging notch when the aiming rod is aimed in the direction of fall. The tool includes angular adjustments to allow marking an aiming notch which compensates for the lean of a tree and/or for trees with trunks of irregular cross section.
Claims20
A tree marking device for use in marking the location on a tree trunk for a hinging notch to be cut in the trunk to encourage the tree to fall with an upper part of the trunk falling to the ground in a desired direction relative to the base of the tree trunk, said device comprising:
- aiming means having direction-pointing means manually movable to a first position at one side of the tree trunk with said direction-pointing means aimed along a first line pointing away from the trunk in said desired direction,
- indicating means partially encircling the tree trunk and identifying the location for a generally horizontal portion of said hinging notch when said aiming means is located adjacent to the tree trunk and said direction-pointing means is aimed in the direction of said first line,
- said aiming means being manually movable to a second position adjacent to the tree trunk in which said direction-pointing means is angularly adjusted relative to said first line by movement of the aiming means to define a second line pointing outwardly and upwardly from the tree trunk and in the same vertical plane as said first line,
- said indicating means providing, when said direction-pointing means is pointed along said second line, an identification of a location for an inclined portion of the hinging notch.
A tree felling accessory device for use in identifying the location on a tree trunk for a hinging notch to be cut in the trunk to encourage the tree to fall with an upper part of the trunk falling to the ground in a desired direction relative to the base of the tree trunk, said device comprising:
- aiming means having direction-pointing means manually movable to a first position at one side of the tree trunk with said direction-pointing means aimed along a first line pointing away from the trunk in said desired direction,
- indicating means partially encircling the tree trunk and having two trunk-engaging parts identifying the location of two respective end points of a generally horizontal portion of said hinging notch when said aiming means is located adjacent to the tree trunk and said direction-pointing means is aimed in the direction of said first line,
- said indicating means being manually movable to a second position adjacent to the tree trunk in which said indicating means is angularly adjusted relative to said horizontal portion of the notch interconnecting said two end points,
- said indicating means providing, when in said second position, an identification of a location for an inclined portion of the hinging notch.
A tree marking device for use in marking the location on a tree trunk for a hinging notch to be cut in the trunk to encourage the tree to fall with an upper part of the trunk falling to the ground in a desired direction relative to the base of the tree trunk, said device comprising:
- aiming means having direction-pointing means manually movable to a first position at one side of the tree trunk with said direction-pointing means aimed along a first line pointing away from the trunk in said desired direction,
- indicating means partially encircling the tree trunk and having means to physically mark the surface of the tree trunk to identify the location for a generally horizontal portion of said hinging notch when said aiming means is located adjacent to the tree trunk and said direction-pointing means is aimed in the direction of said first line,
- said aiming means being manually movable to a second position adjacent to the tree trunk in which said direction-pointing means is angularly adjusted relative to said first line by movement of the aiming means to define a second line pointing outwardly and upwardly from the tree trunk,
- said indicating means providing, when said direction-pointing means is pointed along said second line, an orientation of the means to physically mark the surface of the tree trunk to identify a location for an inclined portion of the hinging notch.
