A machine adapted for barking and cleaning a log, having jet nozzles, and featuring mounting each jet nozzle on its own log feeler arm for individual displacement of the jet nozzles in accordance with the hills and valleys sensed by the log feeler arms at the periphery of the log, whereby to automatically and individually maintain each nozzle at a predetermined spacing from the bark. This log barking and cleaning machine further comprises an endless conveyor defining a log path, a support structure extending around the log path, log feeler arms pivoted at one end to the support structure, and having a liquid jet nozzle at the other end, a spring wire connected to each arm and biasing the latter toward operative log feeling contact with the periphery of the log, means to adjust the bias of each spring wire, and a liquid manifold and hydraulic supply tubes connected to the nozzles to feed pressurized liquid through the nozzles.
In a log barking and cleaning machine defining a path for endwise displacement of at least one log therethrough, the combination comprising a support structure extending transversely to the log path and adjacent the latter, arms pivoted to said support structure in planes extending longitudinally of the log path and intercepting the latter, spring means connected to said arms and inwardly biasing the latter toward operative engagement with a log conveyed endwise along the log path, a liquid jet nozzle secured to each of said arms and inwardly directed toward the log path, and a hydraulic supply system connected to said liquid jet nozzles and arranged to supply liquid under pressure to the latter.
