text: Robert's power loom In 1830, using an 1822 patent, Richard Roberts manufactured the first loom with a cast-iron frame, the Roberts Loom. In 1842 James Bullough and William Kenworthy, made the Lancashire Loom. It is a semiautomatic power loom. Although it is self-acting, it has to be stopped to recharge empty shuttles. It was the mainstay of the Lancashire cotton industry for a century, when the Northrop Loom invented in 1894 with an automatic weft replenishment function gained ascendancy.
  Robert's self acting mule
  Also in 1830, Richard Roberts patented the first self-acting mule. The Stalybridge mule spinners strike was in 1824, this stimulated research into the problem of applying power to the winding stroke of the mule. The draw while spinning had been assisted by power, but the push of the wind had been done manually by the spinner, the mule could be operated by semiskilled labour. Before 1830, the spinner would operate a partially powered mule with a maximum of 400 spindles after, self-acting mules with up to 1,300 spindles could be built.
  The savings that could be made with this technology were considerable.  A worker spinning cotton at a hand-powered spinning wheel in the 18th century would take more than 50,000 hours to spin 100 lb of cotton; by the 1790s, the same quantity could be spun in 300 hours by mule, and with a self-acting mule it could be spun by one worker in just 135 hours.
