Washboard (laundry)
A washboard is a tool designed for hand washing clothing. With mechanized cleaning of clothing becoming more common by the end of the 20th century, the washboard has become better known for its secondary use as a musical instrument. Description and use The traditional washboard is usually constructed with a rectangular wooden frame in which are mounted a series of ridges or corrugations for the clothing to be rubbed upon. For 19th-century washboards, the ridges were often of wood; by the 20th century, ridges of metal were more common. A "fluted" metal washboard was patented in the United States by Stephen Rust in 1833. Zinc washboards were manufactured in the United States from the middle of the 19th century. In the late 20th century and early 21st century, ridges of galvanized steel are most common, but some modern boards are made of glass. Washboards with brass ridges are still made. Many parts of the world still use washboards for washing clothes. Clothes are soaked in ho ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Washboard (musical Instrument)
The washboard and frottoir (from Cajun French "frotter", to rub) are used as a percussion instrument, employing the ribbed metal surface of the cleaning device as a rhythm instrument. As traditionally used in jazz, zydeco, skiffle, jug band, and old-time music, the washboard remained in its wooden frame and is played primarily by tapping, but also scraping the washboard with thimbles. Often the washboard has additional traps, such as a wood block, a cowbell, and even small cymbals. Conversely, the frottoir (zydeco rubboard) dispenses with the frame and consists simply of the metal ribbing hung around the neck. It is played primarily with spoon handles or bottle openers in a combination of strumming, scratching, tapping and rolling. The frottoir or ''vest frottoir'' is played as a stroked percussion instrument, often in a band with a drummer, while the washboard generally is a replacement for drums. In Zydeco bands, the frottoir is usually played with bottle openers, to make a l ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Washboarding
Washboarding or corrugation is the formation of periodic, transverse ripples in the surface of gravel and dirt roads. Washboarding occurs in dry, granular road material with repeated traffic, traveling at speeds above . Washboarding creates an uncomfortable ride for the occupants of traversing vehicles and hazardous driving conditions for vehicles that travel too fast to maintain traction and control. Mechanism Washboarding or corrugation of roads comprises a series of ripples, which occur with the passage of wheels rolling over unpaved roads at speeds sufficient to cause bouncing of the wheel on the initially unrippled surface and take on the appearance of a laundry washboard. Most studies of washboarding pertain to granular materials, including sand and gravel. However, other work suggests that the phenomenon may occur in material which has some binding of particles, e.g. clay-like soils. Highway department experts in the mid-1920s were aware that traffic volume and speed ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
