The Nik-O-Lok Company is a company founded in 1910 with headquarters in Indianapolis, Indiana, that manufactures and leases door locks for pay toilets, along with other types of equipment for public bathrooms. Locks are designed that can be operated by manufacturer-supplied tokens or by quarters.
Canals are waterways channels, or artificial waterways, for water conveyance, or to service water transport vehicles. They may also help with irrigation. It can be thought of as an artificial version of a river. Canals carry free surface flow under atmospheric pressure.
Locksmithing is the science and art of making and defeating locks. Locksmithing is a traditional trade and in many countries requires completion of an apprenticeship. The level of formal education legally required varies from country to country from none at all, to a simple training certificate awarded by an employer, to a full diploma from an engineering college, in addition to time spent working as an apprentice.
The Panama Canal is an artificial 82 km (51 mi) waterway in Panama that connects the Atlantic Ocean with the Pacific Ocean. The canal cuts across the Isthmus of Panama and is a conduit for maritime trade. One of the largest and most difficult engineering projects ever undertaken, the Panama Canal shortcut greatly reduces the time for ships to travel between the Atlantic and Pacific oceans, enabling them to avoid the lengthy, hazardous Cape Horn route around the southernmost tip of South America via the Drake Passage or Strait of Magellan and the even less popular route through the Arctic Archipelago and the Bering Strait.
The Grand Union Canal in England is part of the British canal system. Its main line starts in London and ends in Birmingham, stretching for 137 miles (220 km) with 166 locks. It has arms to places including Leicester, Slough, Aylesbury, Wendover and Northampton.
The Staffordshire and Worcestershire Canal is a navigable narrow canal in Staffordshire and Worcestershire in the English Midlands. It is 46 miles (74 km) long, linking the River Severn at Stourport in Worcestershire with the Trent and Mersey Canal at Haywood Junction by Great Haywood.
The Manchester Bolton & Bury Canal is a disused canal in Greater Manchester, England, built to link Bolton and Bury with Manchester. The canal, when fully opened, was 15 miles 1 furlong (24 km) long. It was accessed via a junction with the River Irwell in Salford. Seventeen locks were required to climb to the summit as it passed through Pendleton, heading northwest to Prestolee before it split northwest to Bolton and northeast to Bury. Between Bolton and Bury the canal was level and required no locks. Six aqueducts were built to allow the canal to cross the rivers Irwell and Tonge and several minor roads.
A lock is a device used for raising and lowering boats, ships and other watercraft between stretches of water of different levels on river and canal waterways. The distinguishing feature of a lock is a fixed chamber in which the water level can be varied; whereas in a caisson lock, a boat lift, or on a canal inclined plane, it is the chamber itself that rises and falls.
The Chesapeake and Ohio Canal, abbreviated as the C&O Canal and occasionally called the "Grand Old Ditch," operated from 1831 until 1924 along the Potomac River from Washington, D.C., to Cumberland, Maryland. The canal's principal cargo was coal from the Allegheny Mountains.
The canal network of the United Kingdom played a vital role in the Industrial Revolution. The canals permitted the creation of wealth, by industry, that led to the British Empire in the Victorian Era. The UK was the first country to develop a nationwide canal network, which expanded to nearly 4,000 miles in length. The canals allowed raw materials to be transported to a place of manufacture, and finished goods to be transported to consumers, more quickly and cheaply than via a land based route.
Windsor Locks is a town in Hartford County, Connecticut, United States. As of the 2010 census, its population was 12,498. It is the site of Bradley International Airport, which serves the Greater Hartford-Springfield region and occupies approximately 1/3 of the town. Windsor Locks is also the site of the New England Air Museum.
The St. Marys River, sometimes written as the St. Mary's River, drains Lake Superior, starting at the end of Whitefish Bay and flowing 74.5 miles (119.9 km) southeast into Lake Huron, with a fall of 23 feet (7.0 m). For its entire length it is an international border, separating Michigan in the United States from Ontario, Canada.
Birmingham Canal Navigations (BCN) is a network of canals connecting Birmingham, Wolverhampton, and the eastern part of the Black Country. The BCN is connected to the rest of the English canal system at several junctions.
A lock is a mechanical or electronic fastening device that is released by a physical object, by supplying secret information, or by a combination thereof or only being able to be opened from one side such as a door chain.
The Worcester and Birmingham Canal is a canal linking Birmingham and Worcester in England. It starts in Worcester, as an 'offshoot' of the River Severn and ends in Gas Street Basin in Birmingham. It is 29 miles (47 km) long. There are 58 locks in total on the canal, including the 30 Tardebigge Locks, one of the largest lock flights in Europe. The canal climbs 428 feet (130 m) from Worcester to Birmingham.
The McAlpine Locks and Dam are a set of locks and a hydroelectric dam at the Falls of the Ohio River at Louisville, Kentucky. They are located at mile point 606.8, and control a 72.9 miles (117.3 km) long navigation pool. The locks and their associated canal were the first major engineering project on the Ohio River, completed in 1830 as the Louisville and Portland Canal, designed to allow shipping traffic to navigate through the Falls of the Ohio.
The Sault Ste. Marie Canal is a National Historic Site in Sault Ste. Marie, Ontario, and is part of the national park system, managed by Parks Canada. It includes a lock to bypass the rapids on the St. Marys River.
The Willamette Falls Locks are a lock system on the Willamette River in the U.S. state of Oregon. Opened in 1873 and closed since 2011, they allowed boat traffic on the Willamette to navigate beyond Willamette Falls and the T.W. Sullivan Dam. Since their closure in 2011 the locks are classified to be in a "non-operational status" and are expected to remain permanently closed.
The Cascade Locks and Canal was a navigation project on the Columbia River between the U.S. states of Oregon and Washington, completed in 1896. It allowed the steamboats of the Columbia River to bypass the Cascades Rapids, and thereby opened a passage from the lower parts of the river as far as The Dalles. The locks were submerged and rendered obsolete in 1938, when the Bonneville Dam was constructed, along with a new set of locks, a short way downstream.
The Mersey and Irwell Navigation was a river navigation in North West England, which provided a navigable route from the Mersey estuary to Salford and Manchester, by improving the course of the River Irwell and the River Mersey. Eight locks were constructed between 1724 and 1734, and the rivers were improved by the construction of new cuts several times subsequently. Use of the navigation declined from the 1870s, and it was ultimately superseded by the Manchester Ship Canal, the construction of which destroyed most of the Irwell section of the navigation and the long cut between Latchford and Runcorn.
The Hulme Locks Branch Canal is a canal in the city of Manchester. It is 200m in length and was built to provide a direct waterway between the Mersey and Irwell Navigation and the Bridgewater Canal. The canal opened in 1838 and was superseded in 1995 by a new lock at Pomona Dock 3. As both of its locks remain closed, the canal is now overgrown.
