 The Crossley firm acquired patents and then devised and patented improvements which placed them in advance of the rest of the trade.One loom, the patent of which became their property, was found capable of weaving about six times as much as could be produced by the old hand loom.Manufacturers of tapestry and Brussels carpets applied to Messrs. Crossley for licences to work their patents, and large sums accrued to them from royalties alone.
