Invention
The spar torpedo was invented during the American Civil War by E. C. Singer, a private engineer who worked on secret projects for the benefit of the Confederate States of America (Singer was the nephew of Isaac Singer, inventor of the sewing machine). Singer's torpedo was detonated by means of a trigger mechanism adapted from a rifle lock (see flintlock mechanism for a similar device). The spring-loaded trigger was detonated by means of a long cord attached to the attacking vessel. The attacking vessel rammed its target, embedding the barbed torpedo in its hull, then backed off. When the attacker reached the limit of the trigger cord, the torpedo was detonated.

Famous quotes containing the word invention:
“In all her products, Nature only develops her simplest germs. One would say that it was no great stretch of invention to create birds. The hawk which now takes his flight over the top of the wood was at first, perchance, only a leaf which fluttered in its aisles. From rustling leaves she came in the course of ages to the loftier flight and clear carol of the bird.”
—Henry David Thoreau (1817–1862)
“His mind was great and powerful, without being of the very first order; his penetration strong, though not so acute as that of a Newton, Bacon, or Locke; and as far as he saw, no judgment was ever sounder. It was slow in operation, being little aided by invention or imagination, but sure in conclusion.”
—Thomas Jefferson (1743–1826)
“Heredity is a strong factor, even in architecture. Necessity first mothered invention. Now invention has little ones of her own, and they look just like grandma.”
—E.B. (Elwyn Brooks)
