Ivan F. Churchill |
Fayetteville, NY |
"This invention relates to power drilling machines or drill presses and has for its object a simple, readily applied control mechanism therefor for withdrawing the drill when the drill encounters undue resistance that would or might break it were the drill operation continued, as when the bore fills up with chips, withdraws the drill and again automatically feeds it in after the bore has been cleaned out by the withdrawal of the drill, combined with a mechanism to reverse or withdraw the drill when the drill has bored to a predetermined depth and stop the drill from feeding at the end of its withdrawal, and to set a manual control by which the drilling operation is initiated to again start the feeding when the manual control is operated to drill a new hole."
This patent was cited in Design patent 162,615 for "automatic drill press feed or the like", which was assigned to Beckett-Harcum Co. |
