Mahogany and tinned-iron patent model of a flour mill dust collector patented in 1879. The introduction of dust-collecting machines to flour factories greatly increased the safety of the milling process, preventing dust-ignited explosions like the one that destroyed Minneapolis' Washburn A Mill in 1878.
Made possible by the Arts and Cultural Heritage Fund through the vote of Minnesotans on November 4, 2008. Administered by the Minnesota Historical Society.
