An account of Campbell’s new invented loom appeared in the Washington Daily National Intelligencer, 18 Mar. 1816: “A young man, whose name is Campbell, is now in this city, for the purpose of procuring a patent for a loom of the most singular construction we have yet seen. It does away the necessity of warping; and when once in operation can be kept so for any length of time, that is, a web may be wove of any desired length, as the cloth is rolled out in such a manner as it can be cut off at any time without stopping the loom. The machinery is very simple, and put in operation merely by turning a crank, and requires but a moment’s inspection to be fully understood. The warp is taken from bobbins or spools There can be no doubt but this new combination of machinery will greatly reduce the expense of fabricating cloth; and will therefore be of much use to our country.”

Walter Janes’s patentee for Virginia was Francis C. Clopper.
