    摘要： Log processing apparatus comprises a cutting machine that defines a substantially vertical cutting plane, feed mechanism that feeds a log through the cutting machine in substantially lengthwise horizontal motion parallel to the cutting plane, a measuring station spaced horizontally and vertically from the cutting machine, and transfer mechanism by which a log is carried in horizontal translatory motion from the measuring station to the feed mechanism. At the measuring station, or before the log reaches that station, it is established in an optimum rotational orientation which is thereafter maintained through transfer of support of the log to a set of jaws on the feed mechanism. At the measuring station a relationship is ascertained between a calculated plane that extends lengthwise in the log and a reference plane defined at the measuring station that has a fixed relationship to the cutting plane. The transfer mechanism comprises supporting elements by which a log is confined against all motion except such translatory motion as is imparted to it by the transfer mechanism. The feed mechanism comprises two pairs of jaws, each pair arranged to clampingly grip a log without causing any shifting of it but also arranged for controlled lateral shifting in unison when gripping a log. Either the transfer mechanism or the feed mechanism translatingly elevates a log to the level for cutting, and after the feed mechanism jaws grip the log they shift it laterally to establish it with said calculated plane in a desired relationship to the cutting plane.

    摘要： For feeding logs to a sawing machine, two parallel horizontal I-beams, at a level above the sawing machine, guidingly support an inner and an outer feed carriage. From each carriage pincers-like log supporting jaws extend obliquely downwardly and in the feed direction. The I-beams provide an inner track that has its rails between the rails of an outer track. The inner carriage is wholly between the rails of the inner track and rides thereon. The outer carriage bridges over both tracks and rides on the outer one, and its jaw operating mechanism has portions above the level of the inner track and other portions extending down from said level that are laterally outside the outer track. The carriages can therefore pass one another and exchange leading/trailing relationship for each successive log. Mechanism is disclosed for causing carriage jaws to close on a positioned log without shifting it but by which the closed jaws can be laterally shifted as desired.

    摘要： An improvement in sawmill feedwork systems of the shotgun type wherein safety means are provided for metering or closing fluid flow relative to the drive system such that the carriage and its load of the feedworks can be immediately stopped in the event of power or mechanical failure. In a preferred embodiment the sawyers lever includes operational means for turning off power, both electrical and mechanical. The sawyers lever is otherwise capable and is provided with structure for remotely controlling fluid flow relative to the operative piston of the feedworks.
