Abstract (en)
[origin: FR2846514A1] The wedge consists of a conical body (10) with a threaded surface (18), and a head (12) containing a ratchet mechanism and a handle (40). After cutting out a wedge-shaped section of wood from the side of the tree trunk in the desired direction of felling, a cut is made in the opposite side and the wedge is inserted into it. By rotating the handle to and fro with a lever the ratchet mechanism, comprising teeth (26) and a pawl (32), turns the conical body, which screws into the cut and opens it up, causing the trunk to tip in the felling direction and eventually fall.
