The McLoughlins' pioneering colour printing of children's books and games required the very best and most advanced printing technology - and that was invented and assigned to the McLoughlins by Campbell. In the mid-1880s, Campbell assigned a large number of his printing-related inventions to the brothers.

What has added to the intrigue of this current eBay sale is that the name of another famous inventor, Charles A. Lieb, appears on it, suggesting that this particular McLoughlin was quite probably owned by Lieb. 
Cooper Union in the 1860s
Lieb was born in Newstead, New York, in 1856, and educated at the Cooper Union for the Advancement of Science and Art in Manhattan. In the mid- to late 1890s, Lieb made his fortune through his ownership of the Georgetown and Tenallytown Railroad Company and a Washington DC electric lighting plant. Lieb devoted the later years of his life to inventing electric vehicles, wireless telegraph machines and a screw elevator.
In 1899, described as a "capitalist" by The New York Times, Lieb was part of a syndicate which took over the Corliss Steam Engine Works in Providence. Later that year he took part in the first run of the Automobile Club of America, driving an electric vehicle in New York. At various times Lieb was a mechanical engineer with the Manhattan Transit Company and a manager for Western Union. In 1900 Lieb was joined by Oberlin Smith, who had invented magnetic recording, in the development of the telephonograph. Four years later Lieb was similarly approached by Nikola Tesla about an electric auto-bus. As an "expert" mechanical engineer connected with General Electric, in 1906 Lieb became a director of the United
Wireless Telegraph Company, which attempted to merge the dominant Marconi and De Forest systems.

In early June 1911 Lieb gave $10,000 in bonds to assist building at his alma mater, the Cooper Union. He died three weeks later, on June 25, 1911.
John McLoughlin
Back to the McLoughlins. John McLoughlin was born in New York City on November 29, 1827, and began his working career as a wood engraver for Elton & Co, run by his father, John McLoughlin Snr, and Robert E.Elton. In 1852, John Jnr began the publication of illustrated books and five years later was joined by his brother Edmund (1834-1889). They operated under the name McLoughlin Brothers, with a factory in Brooklyn and head office on Broadway. Through Campbell, the company was able to pioneer the systematic use of colour printing technologies for children's books. John McLoughlin died in Connecticut on April 27, 1905, aged 77.
Campbell Country Cylinder Press
Finally, let's look at Andrew Campbell, who I feel certain designed the McLoughlin Brothers typewriter. Campbell was born near Trenton, New Jersey, on June 14, 1821. In 1836 he left Trenton to become a driver on a canal. He moved to Alton, Illinois, where he constructed several labour-saving devices. In 1842 he removed to St Louis, where he built an omnibus called the Great Western, the first used in the city, carrying 48 passengers. In 1847, Campbell moved to Columbus, Missouri, where his inventive genius produced a machine for making match and pill boxes. He then devoted his attention to bridge building. He next went to New York City, where he started inventing printing presses.
Campbell became one of the world's most important inventors and manufacturers of
printing presses. He was president of the Campbell Printing Press Company of
Brooklyn. He invented the press-feeding machine in 1853, and
was employed by A.B. Taylor & Co of New York. He built presses for Harper
& Brothers and Frank Leslie, of New York, the first ever produced with table
distribution, as well as the first automatics. In 1858 he engaged in business for
himself; in 1861 he built the Campbell Country Press, which became widely used
throughout the country by newspaper publishers. In 1866 he created the
two-revolution book press and in 1868 an art press for fine illustrations.
Campbell made the first press that printed, inserted, pasted, folded and cut in
one continuous operation. He held 50 patents relating to press building. In 1880
he retired from active business but continued to design machines for the McLoughlin Brothers.
Campbell also invented various devices relating to hat manufacture, steam engineering, machinist's tools,
lithographic machinery and electrical appliances. Between 1858-89 he took out about
125 patents, including in the US, Britain, France and Belgium. His son, Andrew Chambre Campbell
(1856-1926), was also a machine inventor.
Andrew Campbell died in New York City on April 13, 1890, aged 68.
