notes: label: Description
content: This is a patent model of a rag washing machine for papermaking created by Frank A. Cloudman of Cumberland Mills, Maine and patented on December 4, 1877, under U.S. patent No. 197,764. Cloudman’s invention related to improvements in the interior construction of cylinders of the rag-washing engines used in the manufacture of paper. It features spiral buckets that extend from the circumference of the machine toward and slightly past the central outlet, ending at their inner edges in an angular manner. The buckets are additionally pointed toward the longitudinal axis and made of a continuous piece of wood. These buckets, according to Cloudman, are superior to metallic buckets as the action of the chemicals utilized in the process is not harmful to the bucket or the pulp. This patent model displays a late-19th century innovation in making paper out of rags, a common method of papermaking that originated in Europe.
