In the early part of the 20th century the Wilcox Manufacturing Co. manufactured woodworkers' vises and emery grinders. So far as we can tell, the manufacture of grinders had started by 1905 and of vises in about 1907. In 1910, Wilcox merged with another Aurora business, the Richards Manufacturing Co., to create the Richards-Wilcox Manufacturing Co. See that entry for the subsequent history.
