Two bladed spinner on a wire wheel 1967 AMC simulated wire wheel cover with spinner. The spinner or "knock-off" originated with Rudge-Whitworth center lock wire wheels and hubs, which were first patented in 1908. [1] [2] The spinner was a threaded, winged nut designed to keep the wheel fastened to the hub. They were screwed on and "knocked on ...
The Spinning Wheel is also the title/subject of a classic Irish folk song by John Francis Waller. [51] [52] A traditional Irish folk song, Túirne Mháire, is generally sung in praise of the spinning wheel, [53] but was regarded by Mrs Costelloe, who collected it, [54] as "much corrupted", and may have had a darker narrative. It is widely ...
Spinning is an ancient textile art in which plant, animal or synthetic fibres are drawn out and twisted together to form yarn. For thousands of years, fibre was spun by hand using simple tools, the spindle and distaff. After the introduction of the spinning wheel in the 13th century, the output of individual spinners increased dramatically.
The free rotation is intended to help make steering with one hand easier or faster. Some heavy automobiles without a power steering system tended to have heavy and slow responses requiring hand-over-hand turning of the wheel by the driver, and the knob allowed the driver to "crank" the steering wheel to make faster turns. [2]
Just as a bicycle's wheels must be able to rotate faster than the pedals, a rotorcraft's blades must be able to spin faster than its drive engines. This is especially important in the event of an engine failure where a freewheel in the main transmission lets the main and tail rotor systems continue to spin independent of the drive system.
Spinner's weasel (left) and spinning wheel (right) Spinner's weasel or clock reel is a mechanical yarn-measuring device consisting of a spoked wheel with gears attached to a pointer on a marked face (which resembles a clock) and an internal mechanism that makes a "pop" sound after the desired length of yarn is measured (usually a skein ).
Wheels can also lose traction when surface conditions reduce available traction such as on snow and ice. As an open differential delivers only enough torque to cause the "weakest" wheel to spin, if one drive wheel is stationary on a low traction surface (mud, ice, etc.), the deliverable torque is limited to the traction available on it.
Whirligig store. A whirligig is an object that spins or whirls, or has at least one part that spins or whirls. It can also be a pinwheel, spinning top, buzzer, comic weathervane, gee-haw, spinner, whirlygig, whirlijig, whirlyjig, whirlybird, or simply a whirly.
