Description: |
| Most of the patents prior to 1836 were lost in the Dec. 1836 fire. Only about 2,000 of the almost 10,000 documents were recovered. Little is known about this patent. There are no patent drawings available. This patent is in the database for reference only.
“For an improvement in the Grist Mill; Job Wickersham and Thomas Crozier, Fairfield, Columbiana county, Ohio, August 25.
This is another contribution to the number of grist mills which have been proposed for family use. It possesses, and, in fact, lays claim to, but little novelty. The lower stone is to be the runner and is to be 16 inches in diameter. The upper, or stationary stone, is square, and measures 18 inches on the side; it is perforated to allow of feeding. The runner is fixed permanently on the spindle. The claim is to the runner being permanent on the spindle, and the arrangement of the boxing, by which we are enabled to make it tight below and prevent all waste of meal.”
