ABSTRACT:
This invention is directed to an improved stop and loader assembly for use in a sawmill and the like, and more particularly includes an improved combination slapper bar and log turner. The combination slapper bar and log turner preferably includes a rectangular hollow slapper bar section which contains a movable member having a plurality of teeth pivotally attached thereto. A fluid-actuated piston assembly is provided for drawing the movable member and teeth longitudinally in and out of the slapper bar. A slot is further provided in the upper end of the slapper bar and adjacent any sawlog reposing on the carriage next to the slapper bar, whereby the teeth fall out of the slapper bar in an extended position to engage the log when the movable member is thrust upward in the slapper bar, and whereby the teeth fold into the slapper bar whenever the movable member is drawn downward therein.
