The Dietz, Schumacher, and Boye Lathe |
|
24" swing, 14-foot bed This lathe is the gift of Jack Woods of Preston, MD, who also donated our Garvin milling machine. We believe it was once the property of the Kuhner Engine Company of Oxford, MD. Kuhner was a manufacturer of small marine gas engines from about 1905 to 1920. The leadscrew and gears are in excellent (almost unused) condition, while the feed rod key and apron bevel gears are heavily worn. This suggests that the lathe could have been used to turn crankshafts or for boring engine cylinders. Dietz, Schumacher and Boye of Cincinatti, OH existed from 1896 to 1899. This lathe is similar to Figure 14 in Copes' "American Lathe Builders 1810-1910". Some disassembly was performed in 2005, with restoration resuming in January 2006. |

| The back gear pinion had 3 broken teeth. This repair was done by our friends at C & L Machine. | This gear (shown out of position) drives the leadscrew. The "feather key" is slighly tapered and rests on a flat cut or filed into the leadscrew. The gear is then driven onto the key. The key may have been intended to shear, allowing the gear to slip in the event of a crash. |
