Description: |
"The invention is an improvement in the class of upright drilling-machines in which a weight is employed to balance the spindle and its attached drill. My invention relates to prevention of backlash, chiefly by means of a chain, a roll or cylinder, and adjusting-screws; also, to the arrangement for enabling the drill-spindle to be quickly removed from or reinserted in the hole made by it, part of the same devices being employed for the purpose as are used for ordinary feeding of the drill." |
