1I: From James Jay, 20 December 1784 (Washington Papers)
...some cases, even weaves. There are not above 3 or 4 of these Machines in England: The proprietors of them taking great care to conceal their structure, and having a Patent to secure the invention to themselves. This Machine spins faster than can be done in any other way yet known: and the threads spun by it, are much more even than can be done by the hand.
