New York Central Tugboat 13
New York Central Railroad ''Tugboat 13'' was a railway tugboat built in 1887 in Camden, New Jersey by Dialogue & Company, John H. Dialogue and Son. The tugboat was built for the New York Central Railroad to push barges, called car floats, carrying railroad cars and other freight across the waterways of New York Harbor. It originally had a Marine steam engine, steam engine of , replaced with two General Motors 6-110 diesel engines in the 1950s. The engines sat back-to-back and drove a central Falk Corporation, Falk gearbox, which turned the single propeller. The hull was Rivets, riveted and made of wrought iron. After 2002, the tugboat underwent extensive renovation at Garpo Marine in Tottenville, Staten Island. Two new keel coolers from Fernstrum were installed in a recessed box in the hull to cool the engines. Efforts to restore the ship seemingly failed in the intervening years, and she was scrapped in 2017 in Tottenville. Other vessels built by John H. Dialogue and Son * ...

New York Central Railroad
The New York Central Railroad was a railroad primarily operating in the Great Lakes and Mid-Atlantic regions of the United States. The railroad primarily connected greater New York and Boston in the east with Chicago and St. Louis in the Midwest, along with the intermediate cities of Albany, Buffalo, Cleveland, Cincinnati, Detroit, Rochester and Syracuse. New York Central was headquartered in New York City's New York Central Building, adjacent to its largest station, Grand Central Terminal. The railroad was established in 1853, consolidating several existing railroad companies. In 1968, the NYC merged with its former rival, the Pennsylvania Railroad, to form Penn Central. Penn Central went bankrupt in 1970 and merged into Conrail in 1976. Conrail was broken-up in 1999, and portions of its system were transferred to CSX and Norfolk Southern Railway, with CSX acquiring most of the old New York Central trackage. Extensive trackage existed in the states of New York, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Propeller
A propeller (colloquially often called a screw if on a ship or an airscrew if on an aircraft) is a device with a rotating hub and radiating blades that are set at a pitch to form a helical spiral which, when rotated, exerts linear thrust upon a working fluid such as water or air. Propellers are used to pump fluid through a pipe or duct, or to create thrust to propel a boat through water or an aircraft through air. The blades are specially shaped so that their rotational motion through the fluid causes a pressure difference between the two surfaces of the blade by Bernoulli's principle which exerts force on the fluid. Most marine propellers are screw propellers with helical blades rotating on a propeller shaft (ship), propeller shaft with an approximately horizontal axis. History Early developments The principle employed in using a screw propeller is derived from sculling. In sculling, a single blade is moved through an arc, from side to side taking care to keep presenting the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tugboats Of The United States
A tugboat or tug is a marine vessel that manoeuvres other vessels by pushing or pulling them, with direct contact or a tow line. These boats typically tug ships in circumstances where they cannot or should not move under their own power, such as in crowded harbour or narrow canals, or cannot move at all, such as barges, disabled ships, log rafts, or oil platforms. Some are ocean-going, some are icebreakers or salvage tugs. Early models were powered by steam engines, long ago superseded by diesel engines. Many have deluge gun water jets, which help in firefighting, especially in harbours. Types Seagoing Seagoing tugs (deep-sea tugs or ocean tugboats) fall into four basic categories: #The standard seagoing tug with model bow that tows almost exclusively by way of a wire cable. In some rare cases, such as some USN fleet tugs, a synthetic rope hawser may be used for the tow in the belief that the line can be pulled aboard a disabled ship by the crew owing to its lightness c ...

Keel Cooler
A keel cooler is a type of internal combustion engine cooling system used in marine engines. In this system, engine coolant is circulated through a system of tubing outside the vessel's hull, using the lower temperature of seawater to reduce the coolant temperature via heat exchange before it is recirculated through the engine. Simpler designs take the form of a tank within the hull adjacent to the vessel's hull plating. For maximum efficiency, manufacturers design keel coolers with baffles and others means of slowing and disrupting the flow of coolant and/or seawater in order to maximize heat transfer.

Tottenville, Staten Island
Tottenville is a neighborhood on the South Shore of Staten Island, New York City. It is the southernmost settlement in both New York City and New York State. Tottenville is bounded on three sides by water: the south side abuts New York Bight while the west and north sides are bordered by Arthur Kill. Nassau Place, Bethel Avenue and Page Avenue form the neighborhood's eastern border. The settlement was originally named ''Bentley Manor'' by one of its first settlers, Captain Christopher Billop (1638–1726), a member of the Royal Navy, after his own ship. In 1869 it was renamed as Tottenville after John Totten and his prominent local family of that name, some of whom served as Loyalists under Billop during the American Revolutionary War. Tottenville is part of Staten Island Community District 3 and its ZIP Code is 10307 (formerly "Staten Island 7, New York"). Tottenville is patrolled by the 123rd Precinct of the New York City Police Department. Tottenville has been represente ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wrought Iron
Wrought iron is an iron alloy with a very low carbon content (less than 0.08%) in contrast to that of cast iron (2.1% to 4%). It is a semi-fused mass of iron with fibrous slag inclusions (up to 2% by weight), which give it a wood-like "grain" that is visible when it is etched, rusted, or bent to failure. Wrought iron is tough, malleable, ductile, corrosion resistant, and easily forge welded, but is more difficult to weld electrically. Before the development of effective methods of steelmaking and the availability of large quantities of steel, wrought iron was the most common form of malleable iron. It was given the name ''wrought'' because it was hammered, rolled, or otherwise worked while hot enough to expel molten slag. The modern functional equivalent of wrought iron is mild steel, also called low-carbon steel. Neither wrought iron nor mild steel contain enough carbon to be hardenable by heating and quenching. Wrought iron is highly refined, with a small amount of sili ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rivets
A rivet is a permanent mechanical fastener. Before being installed, a rivet consists of a smooth cylindrical shaft with a head on one end. The end opposite to the head is called the ''tail''. On installation, the rivet is placed in a punched or drilled hole, and the tail is ''upset'', or ''bucked'' (i.e., deformed), so that it expands to about 1.5 times the original shaft diameter, holding the rivet in place. In other words, the pounding or pulling creates a new "head" on the tail end by smashing the "tail" material flatter, resulting in a rivet that is roughly a dumbbell shape. To distinguish between the two ends of the rivet, the original head is called the ''factory head'' and the deformed end is called the ''shop head'' or buck-tail. Because there is effectively a head on each end of an installed rivet, it can support tension loads. However, it is much more capable of supporting shear loads (loads perpendicular to the axis of the shaft). Fastenings used in traditional w ...

Marine Steam Engine
A marine steam engine is a steam engine that is used to power a ship or boat. This article deals mainly with marine steam engines of the reciprocating type, which were in use from the inception of the steamboat in the early 19th century to their last years of large-scale manufacture during World War II. Reciprocating steam engines were progressively replaced in marine applications during the 20th century by steam turbines and marine diesel engines. History The first commercially successful steam engine was developed by Thomas Newcomen in 1712. The steam engine improvements brought forth by James Watt in the later half of the 18th century greatly improved steam engine efficiency and allowed more compact engine arrangements. Successful adaptation of the steam engine to marine applications in England would have to wait until almost a century after Newcomen, when Scottish engineer William Symington built the world's "first practical steamboat", the ''Charlotte Dundas'', in 1802.
