Plotting head for use in drawing machine |
| abstract |
A plotting head for use in a drawing machine comprising a housing attached to said drawing machine; a lead holding means installed for vertical movement within said housing and having a vertical through hole; a bias means disposed above said lead holding means and imparting it a continuous descending tendency; a long cover means covering said bias means; a chuck means disposed for vertical movement in the through hole of said lead holding means, provided with a vertical lead inserting hole and having at the lower part a collet portion arranged to shut for clamping the lead and open for releasing the lead depending upon the vertical movement of said chuck means; a gripping means disposed for vertical movement on the bottom wall of said housing and operating to grip the top of the lead; and an actuating means operating to allow said lead holding means to ascend against the force of said bias means. |
