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:
“Of all the inventions of man I doubt whether any was more easily accomplished than that of a Heaven.”
—G.C. (Georg Christoph)
“By whatever means it is accomplished, the prime business of a play is to arouse the passions of its audience so that by the route of passion may be opened up new relationships between a man and men, and between men and Man. Drama is akin to the other inventions of man in that it ought to help us to know more, and not merely to spend our feelings.”
—Arthur Miller (b. 1915)
