Description: |
"My invention relates to improvements in wood and metal working machines; and the object of my invention is to provide an automatic boring-machine which will feed the work to the auger and bore holes into a piece of wood or metal, each hole being removed from the one preceding it any desired distance, and especially arranged for boring holes into the stiles of window-blinds for the purpose of inserting therein the tenons of the blind-slats." |
