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.
As a subcombination,
An engaging member having a portion for engaging the surface of a saw log and the like and further having a pivot point displaced from said engaging portion, a stop portion adjacent said pivot point and displaced from said engaging portion for limiting rotation about said pivot point, a counterweight portion adjacent said stop portion for displacing the center of balance of said engaging member from said pivot and engaging portions, said engaging member having a generally right triangular configuration with two sides corresponding to the hypotenuse and one leg of the right angle forming the engaging portion thereof and with the side corresponding to the other leg of said right angle forming the stop portion of said engaging member, said stop portion of said engaging member being the side corresponding generally to the shorter leg of said right angle and wherein the pivot portion is an aperture located adjacent the intersection of the sides corresponding to the legs of said right angle.
