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:
“Our inventions are wont to be pretty toys, which distract our attention from serious things. They are but improved means to an unimproved end, an end which it was already but too easy to arrive at; as railroads lead to Boston or New York.”
—Henry David Thoreau (18171862)
“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 (18031882)
