The C.A. Edgarton Manufacturing Co. was a textile manufacturing company based in Shirley, Massachusetts. Founded in 1881 by Charles A. Edgarton (1826-1891), its first product was cotton batting, which was used as padding for furniture and other products. The company quickly expanded its operations, however, and began manufacturing a wide range of cotton and woolen products, including blankets, yarns, and fabrics.

By the early 1900s, the company had become one of the largest employers in the region, with several hundred workers employed in its mill complex. At some point, Edgarton Manufacturing began distributing Shirley President Suspenders. President suspenders, also known as Perry suspenders, were first made by Albert Thurston Ltd. in England in the 1820s. These suspenders were originally designed to be worn by British royalty, but their popularity quickly spread, and they became a popular fashion accessory for men around the world. The term “President suspenders” was later adopted in the United States.

Edgarton Manufacturing supplied woolen blankets to the military during World War I and, by the 1920s, had become one of the largest textile manufacturers in the country. However, it later struggled in the face of increased competition from foreign manufacturers and changing consumer preferences. The Shirley President Suspenders brand faded out around 1930. The company began to downsize its operations during the 1930s and, by the 1950s, had ceased production entirely.
