Abstract
Disclosed is apparatus for cutting piling, trees and the like, provided with means permitting the apparatus to be placed about a pile or the like by moving it generally normal to the longitudinal axis of the pile. Specifically, the apparatus comprises longitudinal frame members carrying at one end a driven blade and at the other end a stationary blade or anvil. The stationary blade is mounted on an end cross member, one end of which is pivotally secured to one of the longitudinal frame members and the other end of which is adapted for locking to the other of the members. By pivoting the end member carrying the stationary blade upwardly or out of the general plane of the frame, the device may be opened up so that it may be slipped about a piling or tree, without having to be lowered thereabout as has heretofore been required. Other details include specific means for locking the free end of the member carrying the stationary blade to the longitudinal frame; safety means preventing the actuation of the power source for the movable blade until the stationary blade is properly locked in position; and, a hydraulic system and suitable controls for the apparatus.
