PAIREDDLEVER FULCRUMPOINT TYPE VERTICAL ACTING LARGE HORSEEPOWERED MACHINE

摘要

PURPOSE:To provide a large horse power by a method wherein a sub-lever being continuous with a major lever is arranged, a support column is arranged at a leading end of the sub-lever, a branch rod is mounted at an intermediate point of the lever, a corner wheel is installed at the leading end of the branch rod and abutted against the lower end of the fulcrum rod. CONSTITUTION:When a force applying point of the major lever 1 is pushed down, the sub-lever 7 is also pushed down in cooperative relation with the major lever, the sub-lever rod is pushed with an angle against the column 5 arranged at the leading end of the force applying point of the sub-lever 7 and one of the branch rods arranged at the sub-lever rod 7 pries up the wheel plate 4 and then pushes up the corner wheel. In this way, the fulcrum rod 2 is pushed up under an action of the corner wheel and the wheel plate and so the fulcrum point of the major lever is pushed up further. Therefore, their center of gravities are more lifted up. In this way, the fulcrum point of the major lever is pushed up by the sub-lever and a force applying point is returned thereby and a vertical range of force of the center of gravity is widened to allow an availability of a large horse power.
