        Description: |  
| This tool uses a spring-mounted arm to transfer an irregular shape to another piece, as would be done with skirting boards or moldings. The arm is reversible to allow it to be used right- or left-handed. 
The inventor patented a simplified version of this tool a few months later (459,648 - 9/15/1891). |
