Joseph Makens Merrow established a gunpowder factory in Mansfield, Connecticut. When the mill burned in 1837, he built a knitting factory on the same site. That enterprise, known as J.B. Merrow & Son made knitted textiles, but also opened a machine shop to improve knitting machines. The machine shop developed an over-edging machine in 1877 and by 1888, devoted production entirely to the manufacture of crochet sewing machines. The collection contains patents, 1877-1940 that deal with Joseph Millard Merrow’s improvements for over-edge machines for his company. Included are Merrow’s research, individual applications, memoranda, sketches, and two volumes of patents he received.
