Description: |
Claim:
In mechanism of this character as heretotom usually employed it has been the practice to leave the manually operated handwheel for manually feeding the drill-spindle in operative relation when feeding the drill-spindle by power, with the result that when the drill-spindle was being fed by power the, hand-wheel was also rotating. This has been found to be an objectionable feature in mechanism of this character. |
