Back-Geared, Upright Drilling Machine, 1926

The Starrett Book for Motor Machinists and Auto Repair Men.  Athol, Mass.:  The L.S. Starrett Co., 1926.
These old line drawings are beautiful.

Made by the Aurora Tool Works of Aurora, Indiana, a short-lived firm (approximately 1898-1906).

The tiny script under the base reads "Courtesy of Niles-Bement Pond Co."  This was a huge machine tool manufacturer at one time which, among other acquisitions, bought Pratt & Whitney in 1901.

Large radial drills can have 30" or larger columns, compared to the 6" on some of the biggest pillar drills. On this column is mounted an arm that can swing 360 degrees.
