Pump-rod balance

Boring and tenoning machine
|
Arthur A. Koch |
Montezuma, IA |
In 1903 the Koch Mfg. Co. was manufacturing this boring and tenoning machine. That firm moved to Grinnell, IA and reorganized as the Grinnell Mfg. Co. but as far as we can tell the reorganized firm did not make this machine. A 1911 ad for the Vulcan Iron Works of Mason City, IA, shows this machine.
The inventor must have thought highly of this invention as he also obtained British patent 190,300,091 and Canada patent 84,676 for it; this is his only invention—of which he had several—for which he obtained foreign patents. |

Punching and shearing machine
|
Arthur Alfred Koch |
Montezuma, IA |
This is the "Modern" combined punch and shears as made by the Koch Mfg. Co. of Montezuma, IA. That town was not well suited to a manufacturing business so in 1905 Koch relocated the business to nearby Grinnell and reorganized it as the Grinnell Manufacturing Co. So far as we can tell the latter firm specialized in the Modern power hammer and did not make the shears. |
