Abstract
The invention is a method and apparatus, powered solely by the muscles of a single male adult during a working day; for bundling cut firewood, or the like. The apparatus is located under and over the top of a rugged rectangular work bench. The frame is constructed of welded metal rods, about an inch and a quarter in diameter. The operator can load the apparatus onto a flat bed of a motor vehicle for transport over open roads and across country. The operator faces a full length raceway below the top of the long panel. A lever arm protudes from the raceway toward the operator. A pivot is welded across the raceway, a foot or so back of the pannel. A loose fitting sleeve cover is over th pivot. The lever arm is welded to the loose fitting sleeve cover, its fulcrum. A chain linkage is welded to an end of the lever arm and to the foot of the elevator rod. The chain linkage forms a loop between the two. As theoperator treads downwardly on the lever arm, the chain linkage shortens and in so doing drives the elevator rod and its attached elevator rod carraige, perpendicularly above the work bench. Before the latter movement starts, the operator places wide resilient rubber bands salvaged fr…
