Card-cloth.
The manufacture of cards for carding wool by hand was quite an important industry in America before the Revolution, and was carried on successfully during that war. In 1787 Oliver Evans, the pioneer American inventor, then only twenty-two years of age, and engaged in making card-teeth by hand, invented a machine that produced 300 a minute.
Already Mr. Crittendon, of New Haven, Conn., had invented a machine (1784) which produced 86,000 card-teeth, cut and bent, in an hour.
These inventions led to the contrivance of machines for making card-cloth—that is, a species of comb used in the manufacture of woollen or cotton cloths, for the purpose of carding and arranging the fibres preparatory to spinning.
It consists of stout leather filled with wire card-teeth, and is the chief part of the carding-machine in factories.
A machine for making the card-cloth complete was invented by Eleazar Smith, of Walpole, Mass., at or near the close of the eighteenth century, for which i

Evans, Oliver, 1775-1819
Inventor; born in Newport, Del., in 1775; was of Welsh descent, and was grandson of Evan Evans, D. D., the first Episcopal minister in Philadelphia.
Apprenticed to a wheelwright, he early displayed his inventive genius.
At the age of twenty-two years he had invented a most useful machine for making card-teeth.
In 1786-87 he obtained from the legislatures of Maryland and Pennsylvania the exclusive right to use his improvements in flour-mills.
He constructed a steam-carriage in 1799, which led to the invention of the locomotive engine.
His steam-engine was the first constructed on the high-pressure principle.
In 1803-4 he made the first steam dredging-machine used in America, to which he gave the name of Oracter Amphibolis, arranged for propulsion either on land or water.
This is believed to have been the first instance in America of the application of steam-power to the propelling of a land carriage.
Evans foresaw and prophesied the near era of ra
