Sixteen-inch Light Drill Press
With this we give an engraving of a light drill press reently brought out by F. A. Schumacher & Co. [sic] of Cincinnati, Ohio.
The engraving makes the construction of the press quite plain, and it will be noticed that, although all parts of the machine are made quite light, to adapt it to the rapid drilling of small holes, the column is carried back opposite the table, to admit of holes being drill in plates of sheet metal or other pieces of considerable size.
The largest drill intended to be used in the machine is ½", but it will drill to the center of a 16" circle.
The object of the arrangement of the levers shown is to leave the front of the machine unobstructed, and place the lever for feeding in a convenient position. They also serve to balance the spindle.
An endless round belt for driving is furnished with each machine.
The spindle is ½" diameter, and 1½" traverse, and is fitted for the Morse taper No. 1. The table can be adjusted vertically a distance of 6", and the maximum distance between it and the spindle is 9". There are three changes of speed. The machine weighs about 225 pounds. |
