    • A three-side cutting apparatus which cuts a carried-in book at its top, bottom and side. The apparatus comprises top and bottom size setters; transverse size setter; transfer quantity calculating member for calculating a quantity of transfer of the book to the cutting position on the basis of the signal indicative of the transverse size from the transfer size setter and outputting a signal indicative of the transfer quantity; top and bottom cutters for moving a pair of opposing cutters toward and away from each other under control of the signal indicative of the top and bottom sizes; position adjuster controlled in accordance with the signal indicative of the top and bottom sizes for adjusting the position where the book is fed in; aligner controlled by the signal indicative of the transverse size for moving the aligning position and the position of the back of the book; and feed-in member for setting a movement distance based on the signal indicative of the movement quantity and moving the book to the cutting position.

    • An elongated frame supports a pair of rails for a wheeled log carriage. A winch drum is mounted on the frame between the ends of the latter and drives a cable reeved through opposite end pulleys for moving the carriage in feed and return movements. Multiple pulley V-belt assemblies are provided in the drive unit for the carriage and are operated by a manual lever which in one direction actuates feed movement of the carriage and releases return drive movement and in the other direction of the lever releases the drive for the feed movement and actuates the drive for the return movement. Such actuation and release of the multiple pulley V-belt assemblies is controlled by rocker arm clutches controlled by the manual lever. A log ramp is utilized with the mechanism and has a pull cable powered from the main drive mechanism of the sawmill under control of an operator's lever. A sawdust pickup housing is combined with the saw blade to catch sawdust and a conveyor associated with the pickup housing and driven from the main power drive of the saw delivers the sawdust to the opposite side of the machine for loading into a vehicle.
    • 细长的框架支撑一对用于轮式托盘的轨道。 绞车鼓安装在后者的端部之间的框架上,并驱动通过相对端滑轮收紧的电缆,以使托架在进给和返回运动中移动。 多个皮带轮V形皮带组件设置在用于滑架的驱动单元中,并且由手动操作杆操作,该手动杆在一个方向上致动滑架的进给运动并释放返回驱动运动,并且在杠杆的另一方向释放用于 进给运动并启动驱动器进行返回运动。 多个皮带轮V形皮带组件的这种致动和释放由由手动杆控制的摇臂离合器控制。 该机构采用对数斜坡,并在操纵杆的控制下具有由锯木厂的主驱动机构供电的拉索。 锯屑拾取器壳体与锯片结合以捕获锯屑,并且与拾取器壳体相关联的传送器和从锯的主动力驱动器驱动的输送机将锯屑输送到机器的相对侧以装载到车辆中。
