    摘要： An end-dogging log carriage system has two narrow, carriage sections, supportably guided on an elongated track, interconnected by a drive cable and a clamping cable. Both cables are wrapped around a spooling drum mounted on one of the carriage sections in such a way so that rotation of the spooling drum simultaneously changes the operative length of both clamping and drive cables thereby moving one carriage section with respect to the other to adjust the length of the log carriage and clamp a log therebetween. The tension in the cable system acting at the cable attachment points on each carriage section provides therein a preinduced countermoment in opposition to the dogging moment occurring when a log is dogged. The carriage sections are laterally biased against a single sidemounted guide rail spaced from the supporting track and discontinuous proximate the saws by a preloaded torque shaft mounted on each carriage section. Each carriage section has selectively retractable and extensible turning dogs powered by a hydraulic vane motor capable of rotating a clamped log 90.degree. during processing. The entire carriage system may be used alternatively as an overhead carriage, an underneath carriage, or in tandem as an overhead and underneath log carriage system using one array of log-processing equipment.

    摘要： A set of log support carriage units are supported for horizontal movement by a set of parallel spaced tubular tracks and are connected by an elongated hydraulic cylinder. The carriage units include depending plate-like brackets which support corresponding dog members for engaging the opposite ends of a log when the connecting cylinder is retracted. The main carriage unit includes a variable speed hydraulically driven resilient wheel. The wheel engages the bottom surface of one of the tracks and is effective to move both of the carriage units along the tracks for feeding the log into a pair of rotary saws of a corresponding set of laterally adjustable saw husks. The dog member of the main carriage unit is mounted on one end of an elongated horizontal shaft rotatably supported by the corresponding bracket. The opposite end of the shaft connects with a hydraulic motor which is also supported by the bracket and is controlled by valves positioned adjacent a rotary actuator driven by the shaft through an electrically actuated clutch. The log is rotated to a selected position for the initial cutting operation and is then automatically indexed by precisely 90* from the initial cutting position.

    摘要翻译： 由一组平行间隔的管状轨道支撑一组对数支撑托架单元，用于水平运动，并通过细长的液压缸连接。 托架单元包括悬挂的板状托架，其在连接筒缩回时支撑用于接合木材的相对端的相应的爪构件。 主滑架单元包括变速液压驱动的弹性轮。 车轮与其中一条轨道的底面接合，并有效地沿轨道移动两个滑架单元，以便将原木输送到相应的一组侧向可调节的锯壳的一对旋转锯中。 主托架单元的卡扣构件安装在由相应托架可旋转地支撑的细长水平轴的一端。 轴的相对端与液压马达相连，液压马达也由支架支撑，并由通过电动离合器由轴驱动的转动致动器定位的阀控制。 日志旋转到初始切割操作的选定位置，然后自动从初始切割位置自动转位90°。

    摘要： Apparatus including a horizontally movable carriage slidably supported by a track. A hydraulic cylinder and piston therefor are mounted on the carriage below the track. A fixed clamp is carried by the cylinder and a hinged clamp is mounted on the piston rod with both clamps projecting above the track. The carriage is reciprocated to feed a log, the ends of which are engaged by the two clamps, past cutting elements which straddle the track and clear the clamps. As the empty carriage is returned to the starting position, the hinged clamp folds beneath a preloaded log and later is moved towards the fixed clamp so that the log is gripped therebetween.

    摘要： A supply of logs are successively transferred from an endless deck conveyor to a sawmill carriage by a log transfer rotor and log positioning cradles. The rotor includes a shaft supporting a plurality of axially spaced transfer elements each having diametrically opposed recesses for receiving logs. The log positioning cradles are arranged in parallel relation to the rotor and are supported for vertical movement by corresponding fluid cylinders. The log transfer rotor and deck conveyor are independently driven by corresponding motors which are operated in timed relation by an automatic control system.
