Abstract: In abstract, a preferred embodiment of the present invention is a lumber spacer which automatically separates lumber in parallel alignment, drops spacer sticks on top of the stacked lumber, and then stacks further lumber thereon. The stick layer portion of the present invention is of such design that warped, bent or other normally unsuitable sticks can be used without affecting the laying operation or the subsequent stacking operation.

Abstract: A package liner adapted to protect fragile articles during shipment, handling and display in retail establishments. The liner is made of an elongated, flexible packaging material, such as a single face corrugated paper pad, having a pair of spaced, oppositely disposed, outwardly bowed lines of weakness impressed across its central width. When the ends of the liner are folded upwardly and flexed into a generally tubular conformation, the area between the lines of weakness assumes a downwardly concave shape. The resulting U-shaped structure is adapted to receive the article therewithin and cushion it against breakage when the package is dropped or exposed to lateral shock forces.

Abstract: A hermetically sealed pouch which is pleated, provided with a line of weakness and a tear initiating cut adjacent the line of weakness. The line of weakness extends completely around the pouch near the top of the package. A sealed area surrounds the cut to establish a barrier between the cut and the pouch interior. In one embodiment two parallel lines of weakness are used and the cut is made in the material which intervenes.

Abstract: Interconnecting bars are employed to connect two standard bicycles in a side-by-side relationship.
