<p>A button applicator with a one-rotation clutch (4) linked to a foot pedal (7) and is released by a disconnecting and connecting mechanism (24). A safety member (8) is provided between a punch (2) and a die (1) and urged upward. A swing lever (13) is linked to the safety member (8) at its one end and linked to an operation rod (16) connected to the foot pedal (7) at its substantial center and swings about another end of the swing lever (13). A means (20) for shutting off the clutch (4) is provided between the operation rod (16) and the swing lever (13). A means (21, 22, 23) for allowing the rotation of the clutch (4) is provided between the operation rod (16) and the connecting and disconnecting mechanism (24). According to a preferred embodiment, the means for allowing the rotation of said clutch comprises an intermediate rod (22) linked to the connecting and disconnecting member (24) and having a stopper (23) at its end and an interconnecting member (21) interconnecting the two rods, and the means (20) for shutting off the clutch (4) comprises a sliding bearing (15) fixed to the swing lever (13), a collar (17) mounted on the sliding bearing (15) and a spring (19) between the sliding bearing (15) and a rod end (18). The relational movements of above mentioned two means release the clutch to rotate through the connecting and disconnecting mechanism. Finally, the punch (2) linked to the clutch (4) is brought down for caulking button elements when the operation rod (16) is brought down to a deeper position by a predetermined interval (D) than a predetermined position of the safety member being brought down.</p> |
