Inventions
In 1843, Richard invented a lithographic rotary printing press that placed the type on a revolving cylinder, a design much faster than the old flatbed printing press. It received U.S. Patent 5,199 in 1847, and was placed in commercial use the same year. In its early days, it was variously called the "Hoe lightning press," and "Hoe's Cylindrical-Bed Press," and was later developed into the "Hoe web perfecting press."
In 1870 he developed a rotary press that printed both sides of a page in a single operation. Hoe's press took a roll of paper five miles long, which was put through the machine at the rate of 800 feet (240 m) a minute. As the sheets came out, they were passed over a knife which cut them apart, and then they were then run through an apparatus which folded them for the mail or for carriers. These completely printed and folded newspapers were delivered as quickly as the eye could follow them.
Early on, Hoe added the production of steel saws to his business and introduced improvements to their manufacture. In 1837, he visited England and obtained a patent for a better process of grinding saws. In connection with his factory, Hoe established an apprentice's school where free instruction was given.
Hoe was a Freemason, and died in Florence, Italy. His nephew, Robert Hoe (1839–1909), wrote a notable Short History of the Printing Press in 1902 and made further improvements in printing.

Famous quotes containing the word inventions:
“Young children constantly invent new explanations to account for complex processes. And since their inventions change from week to week, furnishing the “correct” explanation is not quite so important as conveying a willingness to discuss the subject. Become an “askable parent.””
—Ruth Formanek (20th century)
“In America the geography is sublime, but the men are not; the inventions are excellent, but the inventors one is sometimes ashamed of.”
—Ralph Waldo Emerson (1803–1882)
“The treasury of America lies in those ambitions and those energies that cannot be restricted to a special, favored class. It depends upon the inventions of unknown men; upon the originations of unknown men, upon the ambitions of unknown men. Every country is renewed out of the ranks of the unknown, not out of the ranks of those already famous and powerful and in control.”
—Woodrow Wilson (1856–1924)
