Elbow Of Cross Ledge Light
The Elbow of Cross Ledge Light was a lighthouse on the north side of the ship channel in Delaware Bay in Cumberland County, New Jersey, Cumberland County, New Jersey, on the East Coast of the United States, east coast of the United States, west of Egg Island Point. It was destroyed by a ship collision in 1953 and replaced by a skeleton tower on the same foundation. History This light was built to replace the Cross Ledge Light, which stood somewhat to the south-east. A projection from Cross Ledge shoal forces a slight turn in the ship channel, and it was felt that light on this projection (the "elbow") would be more useful than the older light, which stood at some distance from the present channel. Construction of the new light was considerably delayed from the first United States Congress, congressional appropriation in 1904. Advertisement for bids had to be repeated as there were no submissions in the first round. In addition, the setting and completion of the caisson (engineeri ...

Delaware Bay
Delaware Bay is the estuary outlet of the Delaware River on the northeast seaboard of the United States. It is approximately in area, the bay's freshwater mixes for many miles with the saltwater of the Atlantic Ocean. The bay is bordered inland by the states of Delaware and New Jersey, and the Delaware Capes, Cape Henlopen and Cape May, on the Atlantic. Delaware Bay is bordered by six counties: Sussex, Kent, and New Castle in Delaware, along with Cape May, Cumberland, and Salem in New Jersey. The Cape May–Lewes Ferry crosses Delaware Bay from Cape May, New Jersey, to Lewes, Delaware. The bay's ports are managed by the Delaware River and Bay Authority. The shores of the bay are largely composed of salt marshes and mudflats, with only small communities inhabiting the shore of the lower bay. Several of the rivers hold protected status for their salt marsh wetlands bordering the bay, which serves as a breeding ground for many aquatic species, including horseshoe crabs. The bay ...

Scow
A scow is a smaller type of barge. Some scows are rigged as sailing scows. In the 19th and early 20th centuries, scows carried cargo in coastal waters and inland waterways, having an advantage for navigating shallow water or small harbours. Scows were in common use in the American Great Lakes and other parts of the U.S., Canada, southern England, and New Zealand. In modern times their main purpose is for recreation and racing. Scows The name "scow" derives from the Dutch , ultimately from the German for a punt pole and subsequently transferred to mean the boat. Old Saxon has a similar word which means to push from the shore, clearly related to punting. The basic scow was developed as a flat-bottomed barge ( a large punt) capable of navigating shallow rivers and sitting comfortably on the bottom when the tide was out. By 1848 scows were being rigged for sailing using leeboards or sliding keels. They were also used as dumb barges towed by steamers. Dumb scows were used for a ...

Lighthouses Completed In 1910
A lighthouse is a tower, building, or other type of physical structure designed to emit light from a system of lamps and lenses and to serve as a beacon for navigational aid, for maritime pilots at sea or on inland waterways. Lighthouses mark dangerous coastlines, hazardous shoals, reefs, rocks, and safe entries to harbors; they also assist in aerial navigation. Once widely used, the number of operational lighthouses has declined due to the expense of maintenance and has become uneconomical since the advent of much cheaper, more sophisticated and effective electronic navigational systems. History Ancient lighthouses Before the development of clearly defined ports, mariners were guided by fires built on hilltops. Since elevating the fire would improve the visibility, placing the fire on a platform became a practice that led to the development of the lighthouse. In antiquity, the lighthouse functioned more as an entrance marker to ports than as a warning signal for reefs and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Coast Guard
The United States Coast Guard (USCG) is the maritime security, search and rescue, and law enforcement service branch of the United States Armed Forces and one of the country's eight uniformed services. The service is a maritime, military, multi-mission service unique among the United States military branches for having a maritime law enforcement mission with jurisdiction in both domestic and international waters and a federal regulatory agency mission as part of its duties. It is the largest and most powerful coast guard in the world, rivaling the capabilities and size of most navies. The U.S. Coast Guard is a humanitarian and security service. It protects the United States' borders and economic and security interests abroad; and defends its sovereignty by safeguarding sea lines of communication and commerce across vast territorial waters spanning 95,000 miles of coastline and its Exclusive Economic Zone.

USS Hansford (APA-106)
USS ''Hansford'' (APA-106) was a that served with the US Navy during World War II. Originally christened ''Sea Adder'', the vessel was launched 25 April 1944 as ''Gladwin''There appears to be some confusion as to the name of APA-106. Some sources say the ship was named ''Gladwin'' by Western Pipe & Steel and named USS ''Hansford'' by the Navy, others say she was initially named USS ''Gladwin'' by the Navy who later changed her name to USS ''Hansford''. Still others say she was initially named USS ''Hansford'' by the Navy and then renamed USS ''Gladwin''. The majority of sources however, refer to her during her operational career as USS ''Hansford''. by Western Pipe & Steel of San Francisco, under Maritime Commission contract. She was transferred to the Navy and renamed ''Hansford'' (after Hansford County, Texas) on 25 August, and commissioned on 12 October 1944.

Isthmian Steamship Company
The Isthmian Steamship Company was a shipping company founded by US Steel in 1910. Isthmian Steamship was the brainchild of US Steel President James A. Farrell, who had connections with the maritime industry through his father's trade as a ship's master. Farrell realized that US Steel could save substantial sums of money by owning its own fleet of freighters, rather than chartering cargo space from other companies. Farrell named the company after the Isthmus of Panama, in honour of America's recent construction achievement, the Panama Canal. Farrell headquartered Isthmian Steamship in London, partly in order to take advantage of Great Britain's respected name in the industry, and partly to benefit from Britain's long history of maritime experience. Management of the company was assigned to the British Federal Steam Navigation Co Ltd, a company which traced its own origins back as far as 1782 with the British East India Company. The US end of Farrell's new company was managed by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Miah Maull Shoal Light
The Miah Maull Shoal Light is a lighthouse on the north side of the ship channel in Delaware Bay, off of Cumberland County, New Jersey on the East Coast of the United States, southwest of the mouth of the Maurice River. History This light, the last offshore lighthouse to be erected in Delaware Bay, marks one of a series of shoals along the eastern side of the shipping channel, between the Elbow of Cross Ledge Light and the Brandywine Shoal Light. The name of the shoal commemorates Nehemiah Maull, a river pilot who was drowned in 1780 when the ship in which he intended to sail to England in order to make a claim on an inheritance was wrecked on the then-unnamed shoal. This light and the Elbow of Cross Ledge Light were intended to replace the Cross Ledge Light, and appropriations for both were first requested in 1904. In the case of this light construction was delayed by the inability of the first contractor to set the caisson before exhausting the budget, so that the caisson wa ...

Life Jacket
A personal flotation device (PFD; also referred to as a life jacket, life preserver, life belt, Mae West, life vest, life saver, cork jacket, buoyancy aid or flotation suit) is a flotation device in the form of a vest or suite that is worn by a user to prevent the wearer from drowning in a body of water. The device will keep the wearer afloat with their head and mouth above the surface – they do not have to swim or tread water in order to stay afloat and can even be unconscious. PFDs are commonly worn on small watercraft or other locations where accidental entry into deep water may occur in order to provide immediate support for the wearer should they end up in the water. PFDs are also kept on large vessels for passengers to wear in an emergency in order to help them stay afloat should they be forced to enter the water or accidentally fall overboard during an evacuation. PFD's are commonly worn for swimming and/or other activities that require an individual to be in the water ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Philadelphia Evening Bulletin
The ''Philadelphia Bulletin'' was a daily evening newspaper published from 1847 to 1982 in Philadelphia, Pennsylvania. It was the largest circulation newspaper in Philadelphia for 76 years and was once the largest evening newspaper in the United States. Its widely known slogan was: "In Philadelphia, nearly everybody reads ''The Bulletin''." Describing the ''Bulletin''s style, publisher William L. McLean once said: "I think the ''Bulletin'' operates on a principle which in the long run is unbeatable. This is that it enters the reader's home as a guest. Therefore, it should behave as a guest, telling the news rather than shouting it." As ''Time'' magazine later noted: "In its news columns, the ''Bulletin'' was solid if unspectacular. Local affairs were covered extensively, but politely. Muckraking was frowned upon." History 1847 to 1895 ''The Bulletin'' was first published by Alexander Cummings on April 17, 1847, as ''Cummings’ Evening Telegraphic Bulletin''.''Cummings’ E ...

Caisson (engineering)
In geotechnical engineering, a caisson ( or ; borrowed from French ''caisson'', from Italian ''cassone'', meaning ''large box'', an augmentative of ''cassa'') is a watertight retaining structure used, for example, to work on the foundations of a bridge pier, for the construction of a concrete dam, or for the repair of ships. Caissons are constructed in such a way that the water can be pumped out, keeping the work environment dry. When piers are being built using an open caisson, and it is not practical to reach suitable soil, friction pilings may be driven to form a suitable sub-foundation. These piles are connected by a foundation pad upon which the column pier is erected. Caisson engineering has been used at least since the 18th century, and was notably used in the construction of the Brooklyn Bridge, which was completed in 1883. Types To install a caisson in place, it is brought down through soft mud until a suitable foundation material is encountered. While bedrock is pref ...

Fresnel Lens
A Fresnel lens ( ; ; or ) is a type of composite compact lens developed by the French physicist Augustin-Jean Fresnel (1788–1827) for use in lighthouses. It has been called "the invention that saved a million ships." The design allows the construction of lenses of large aperture and short focal length without the mass and volume of material that would be required by a lens of conventional design. A Fresnel lens can be made much thinner than a comparable conventional lens, in some cases taking the form of a flat sheet. The simpler dioptric (purely refractive) form of the lens was first proposed by Count Buffon and independently reinvented by Fresnel. The ''catadioptric'' form of the lens, entirely invented by Fresnel, has outer elements that use total internal reflection as well as refraction; it can capture more oblique light from a light source and add it to the beam of a lighthouse, making the light visible from greater distances. Description The Fresnel lens redu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
