PROBLEM TO BE SOLVED: To quickly and surely turn laterally a timber from an L-shaped pedestal without scattering the timber.SOLUTION: An original side and a middle side of a rigid frame 62 are respectively supported with a rigid member so as to suspend them in a manner of capable of oscillating. An upper end side of a first link member 74 is connected to an L-shaped plate 73, so that the first link member extends from a bent part of the L-shape toward an oblique lower side of the original side. The other end of a second link member 75 whose one end is connected to a tip end part of the rigid frame 62 is connected to a lower end side of the first link member 74. A slight upper side of the middle side of the first link member 74 is connected to the other end of a connection rod 86 whose one end is connected to a crank arm 85. An upper end side of a third link member 76 is connected to the L-shaped plate 73 so that the third link member extends from a vertical part toward an oblique lower side of the tip end side, and an upper end side of a fourth link member 77 is connected to the L-shaped plate so that the fourth link member extends from a horizontal part to an oblique lower side of the original side, and lower end sides of the third and fourth link members are connected to the rigid frame 62.SELECTED DRAWING: Figure 8 |
