Other Inventions
While working on the sandblasting process, he was also engaged in the working of stone, which caused him to invent a production method for iron shot - pouring a stream of molten metal onto a revolving surface, from which the globules would be propelled into cold water (US patent 187,239, 1872). This material was in great demand for the cutting of stone.
Around 1880, he invented the sulfite method of fiber reduction for paper production; this was a critical part of the production of paper from wood pulp, competing with the Kraft process.
He also patented a design for a torpedo to be propelled “rocket fashion” by a slow burning powder. It was not successful. He was assisted in this venture by his nephew, Benjamin C. Tilghman II.
He died on July 3, 1901 (1901-07-04) (aged 79), and is buried in the churchyard of St. James the Less Episcopal Church in Philadelphia.

Famous quotes containing the word inventions:
“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)
“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)
