"Millstone Dress" Patents
|This page contains patents for the "dress" of the stone, or
the pattern of lands and grooves which make up the grinding surface of a
millstone. It appears to me that there were probably as many styles of
dress as there were manufacturers. The images on this page cover
the period from 1840 to 1858.
If you would like to view all of the patent images for these, just click on the link below the stone. That will take you to the USPTO page for that patent. Click on the "Images" button to go to the first page of drawings. Just follow the little arrow buttons in the left side of the page to view the rest of the pages. These images require the use of a special "tiff" viewer which can be freely downloaded at http://www.alternatiff.com/
