Sir Richard Arkwright, an English barber, orig-inally, is justly regarded as the founder of the fac-tory system, if not the inventor of the spinning-jenny. Others had invented machinery for weaving,but he utilized the mule spinner and the various ap-pliances for converting raw cotton into cloth. It. was not, however, until the cotton mills of Waltham,Massachusetts, were set up (1813) that machines forall the processes which convert the raw cotton intocloth were combined in one establishment. Themechanism for weaving,dyeing,and the like, receiveda great many improvements from time to time fromAmerican artisans. What is called the system of assembling is aconspicuous feature of American ingenuity. Knightdefines it as the system of making the componentparts of a machine or imple-ment in distinct pieces offixed shape and dimensions,so that corresponding partsare interchangeable. Thefirst watch made in thiscountry was the Americanof Waltham, Massachusetts,and in regard to it Knightobserves, The Americansystem of watch-making, bygathering all the operationsunder one roof, making theparts as largely as possibleby machines, each partbeing made in quantities bygauge and pattern, andpieces afterwards assem-bled, dates back to L.
