Abstract: A seat back hinge for a seat on a fishing boat in which the hinge pivot has a generally circular outer pivot wall on one section of the hinge and a generally circular inner pivot wall on the other portion or section of the hinge. The inner wall is of a size that allows it to fit closely inside the outer wall. The inner wall is provided with ears that project at right angles to the top of the inner wall and the outer wall is provided with relieved sections or bays that allow the ears to pass through the outer wall in only one orientation of the two sections of the hinge. Once the seat has been assembled the movement of the two sections of the hinge are limited in such a way so that it is impossible for the ears on the inner wall to be removed back through the relieved sections of the outer wall. Concentric shield portions keep fingers out of the hinge. Integral stops limit movement and an integral leaf spring catches a detent to lock the hinge in one position.

Abstract: A stacking packaging machine and a process for stacking and packaging resilient workpieces. The workpieces are usually rolled paper products. The machine is comprised of an input conveyor, an elevator, cams, workpiece holders, a packaging film feeder and an output conveyor. A first group of workpieces is placed upon the elevator by the input conveyor and the elevator is lowered. The workpiece holders are brought into place. A second group of workpieces are fed into the holders and held above the first group. The elevator begins to rise and the second group of workpieces are released. The stacked workpieces rise on the elevator toward the output conveyor. Packaging film is fed over the stacked workpieces. The film drapes over the workpieces as they rise preventing any workpieces from falling off the stack. The workpieces enter the output conveyor and are moved to final processing. The timing of the whole sequence is controlled by the cams.
