Even after carriers were restricted to working only with the mail during their work hours, companies advertised items that carriers could use in off-hours to make money. In this instance, the Chicago Flexible Shaft Company purchased advertisements in a 1912 issue of RFD News to remind carriers that clipping horses was a good way to make extra money. Of course, once carriers had finished the day’s route and work, there were no restrictions on their time. The popularity of horse clipping advertisements in several issues of RFD News suggests that a number of carriers took advantage of this idea. The company was founded by John K. Stewart and Thomas J. Clark, sellers of mechanical horse clippers. In the early 20th century it became a subsidiary of the British firm, Wm. Cooper & Nephews, and expanded to manufacture electrical irons, coffeemakers, and toasters. In 1946 the company became the Sunbeam Corporation.
