International ClassB23B 045/14AbstractAn improved drill stand is provided which includes a stand column slidably connected to a bearer unit so that the position or height of the bearer unit with respect to the stand column may be adjusted. The bearer unit includes a gear segment which is biased toward the retracted position by a reset spring. The gear segment is meshed with a geared slide rod. The geared slide rod may be disposed parallel to or perpendicular to the stand column. The slide rod is connected to a machine receiving part. Rotation of the gear segment with respect to the bearer unit against the bias of the reset spring results in movement of the slide rod in the machine receiving part towards an extended position. The machine receiving part is also connected to a bit stop rail. The bit stop rail is connected to a bit stop. The position of the bit stop along the bit stop rail is also adjustable. Movement of the machine receiving part towards the extended position is limited by engagement of the bit stop with the bearer unit.Field of SearchWITH STOPPING UPON COMPLETION OF PRESCRIBED OPERATIONWITH SIGNAL, INDICATOR, ILLUMINATOR OR OPTICAL MEANS Movable relative to tool along tool-axis Including means to move tool With means to bias tool away from work Rack and pinion Manually moved lever Adjustable stop DRILL PRESS ADAPTED TO USE PORTABLE HAND DRILL | |
