Joshua Hendy Iron Works
The Joshua Hendy Iron Works was an American engineering company that existed from the 1850s to the late 1940s. It was at one time a world leader in mining technology and its equipment was used in constructing the Panama Canal, amongst other major projects. The company went on to serve many different markets during the course of its existence, but is perhaps best remembered today for its contribution to the American shipbuilding industry during World War II. Beginnings The company was named after its founder Joshua Hendy. Born in Cornwall, England in 1822, Hendy at the age of 13 migrated with two brothers to South Carolina in the United States. Joshua married and became a blacksmith in Houston, Texas. After the death of his wife and two children from yellow fever, he sailed around Cape Horn to San Francisco in 1849 to participate in the California Gold Rush. Hendy built California's first redwood lumber mill, the Benicia Sawmill (the region is now known as the Hendy Woods State ...

Lumber Mill
A sawmill (saw mill, saw-mill) or lumber mill is a facility where logs are cut into lumber. Modern sawmills use a motorized saw to cut logs lengthwise to make long pieces, and crosswise to length depending on standard or custom sizes (dimensional lumber). The "portable" sawmill is simple to operate. The log lies flat on a steel bed, and the motorized saw cuts the log horizontally along the length of the bed, by the operator manually pushing the saw. The most basic kind of sawmill consists of a chainsaw and a customized jig ("Alaskan sawmill"), with similar horizontal operation. Before the invention of the sawmill, boards were made in various manual ways, either rived (split) and planed, hewn, or more often hand sawn by two men with a whipsaw, one above and another in a saw pit below. The earliest known mechanical mill is the Hierapolis sawmill, a Roman water-powered stone mill at Hierapolis, Asia Minor dating back to the 3rd century AD. Other water-powered mills followed ...

Liberty Ship
Liberty ships were a ship class, class of cargo ship built in the United States during World War II under the Emergency Shipbuilding Program. Although British in concept, the design was adopted by the United States for its simple, low-cost construction. Mass-produced on an unprecedented scale, the Liberty ship came to symbolize U.S. wartime industrial output. The class was developed to meet British orders for transports to replace ships that had been lost. Eighteen American shipyards built 2,710 Liberty ships between 1941 and 1945 (an average of three ships every two days), easily the largest number of ships ever produced to a single design. The Liberty ship was effectively superseded by the Victory ship, a somewhat larger, materially faster, more modern-powered vessel of generally similar design. Over 500 were built between 1943 and 1945. Liberty ship production mirrored (albeit on a much larger scale) the manufacture of "Hog Islander" and similar standardized ship types duri ...

Western Pipe & Steel
The Western Pipe and Steel Company (WPS) was an American manufacturing company that is best remembered today for its construction of ships for the Maritime Commission in World War II. It also built ships for the U.S. Shipping Board in World War I and took part in the construction of the giant Grand Coulee Dam project in the 1930s. Early history The origins of the company are somewhat obscure. It appears it was organized in Los Angeles, California around 1907 by two brothers named Talbot and possibly a partner named T. A. Hays. Hays, a businessman with 21 years experience in the steel industry, was at some stage appointed Vice President of the new company, which in this period was a small-calibre steel pipe and metal casings manufacturer. An early President of the company was James A. Talbot, later to make and lose a fortune as the head of the Richfield Oil Company. Western Pipe & Steel quickly began to expand its operations. In 1910 it established a factory in Taft, California ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Triple Expansion Engine
A steam engine is a heat engine that performs mechanical work using steam as its working fluid. The steam engine uses the force produced by steam pressure to push a piston back and forth inside a cylinder. This pushing force can be transformed by a connecting rod and crank into rotational force for work. The term "steam engine" is most commonly applied to reciprocating engines as just described, although some authorities have also referred to the steam turbine and devices such as Hero's aeolipile as "steam engines". The essential feature of steam engines is that they are external combustion engines, where the working fluid is separated from the combustion products. The ideal thermodynamic cycle used to analyze this process is called the Rankine cycle. In general usage, the term ''steam engine'' can refer to either complete steam plants (including boilers etc.), such as railway steam locomotives and portable engines, or may refer to the piston or turbine machinery alone, as ...

1906 San Francisco Earthquake
At 05:12 AM Pacific Time Zone, Pacific Standard Time on Wednesday, April 18, 1906, the coast of Northern California was struck by a major earthquake with an estimated Moment magnitude scale, moment magnitude of 7.9 and a maximum Mercalli intensity scale, Mercalli intensity of XI (''Extreme''). High-intensity shaking was felt from Eureka, California, Eureka on the North Coast (California), North Coast to the Salinas Valley, an agricultural region to the south of the San Francisco Bay Area. Devastating fires soon broke out in San Francisco and lasted for several days. More than 3,000 people died and over 80% of the city was destroyed. The event is remembered as the List of disasters in the United States by death toll, deadliest earthquake in the history of the United States. The death toll remains the greatest loss of life from a natural disaster in California's history and high on the list of worst American disasters.

Ball Mill
A ball mill is a type of grinder filled with grinding balls, used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis. The axis of the shell may be either horizontal or at a small angle to the horizontal. It is partially filled with balls. The grinding media are the balls, which may be made of steel ( chrome steel), stainless steel, ceramic, or rubber. The inner surface of the cylindrical shell is usually lined with an abrasion-resistant material such as manganese steel or rubber lining. Less wear takes place in rubber lined mills. The length of the mill is approximately equal to its diameter. The general idea behind the ball mill is an ancient one, but it was not until the Industrial Revo ...

Stamp Mill
A stamp mill (or stamp battery or stamping mill) is a type of Mill (grinding), mill machine that crushes material by pounding rather than Mill (grinding), grinding, either for further processing or for extraction of metallic ores. Breaking material down is a type of unit operation. Description A stamp mill consists of a set of heavy steel (iron-shod wood in some cases) stamps, loosely held vertically in a frame, in which the stamps can slide up and down. They are lifted by Cam (mechanism), cams on a horizontal rotating camshaft, shaft. As the cam moves from under the stamp, the stamp falls onto the ore below, crushing the rock, and the lifting process is repeated at the next pass of the cam. Each one frame and stamp set is sometimes called a "battery" or, confusingly, a "stamp" and mills are sometimes categorised by how many stamps they have, i.e. a "10 stamp mill" has 10 sets. They usually are arranged linearly, but when a mill is enlarged, a new line of them may be construct ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
