Abstract
A power hand drill is clamped in the carriage which is slideably mounted on the vertical column. The lever arm is moved about a fixed pivot to control movement of the carriage. The lever arm is tubular and has a push rod extending from the handle into the interior of the housing to actuate a switch which, when closed, connects the power supply cord to a receptacle into which the drill power cord is plugged. The drill power switch is tied in the closed position. Therefore the user can control drill feed and operation with one hand.
