Helical gearing is a modification of ordinary toothed gearing in which the pitch surfaces may be cylinders or cones (as in spur or bevel gearing); but the teeth intersect the pitch surfaces in helical lines. These wheels work much more smoothly and provide more resilience than ordinary gearing.

The first completely automated loom was made by Jacques Vaucanson in 1745. A different power loom was built by Edmund Cartwright in 1785. Originally, powered looms were shuttle-operated but in the early part of the 20th century the faster and more efficient shuttleless loom came into use. Today, advances in technology have produced a variety of looms designed to maximize production for specific types of material. The most common of these are air-jet looms and water-jet looms. Computer-driven looms are now also available to individual (non-industrial) weavers. Industrial looms can weave at speeds of six rows per second and faster.

"The Atwood machine consists of a wheel or pulley, R, over the grooved edge of which are balanced two equal weights suspended by a long silk thread which is both light and strong. The axle of this wheel is preferably supported upon the circumfrences of four friction wheels, r, r, r', r', for greater delicacy of motion. As the thread is so light that its weight may be disregarded, it is evident that the weights will be in equilibrium whatever their position." — Avery, 1895

"A screw is a cylinder with a helical proection winding around its circumference. This helix is called the thread of the screw. The distance that a point of the helix is drawn back or advanced in the direction of the length of the screw during one turn is called the pitch of the screw." —Hallock 1905
