Abstract

PURPOSE: To provide a drive force suppementing system, which is simple in construction and inexpensive, without using liquid pressure or any clutch by taking out the drive force of the drive source of the machine as auxiliary drive force for the operating system through a cam or oscillating plate.
CONSTITUTION: When a connecting rod 25a is withdrawn, a rotative member 25 is rotated to cause rotation of a lever support 21 in the clockwise direction. As a result, a lever 20 is rotated in the clockwise direction about a horizontal shaft 4 by a plate spring 21c mounted on a lever support 21, causing movement of an arm 41 along a flat shaft 4. When a roller 14a rotatably mounted on the arm 14 is brought into contact with a cam 7, which has a spiral form and is always rotated by a drive pulley 5, it is brought into engagement with successive postions of progressively greater diameters of the cam 7. Thus, the arm 14 is rotated in the clockwise direction about the horizontal shaft 3 to operate a conneting rod 26 for operation.
