Sparks Shot Tower
The Sparks Shot Tower is a historic shot tower located at 129-131 Carpenter Street in Philadelphia, Pennsylvania. Opened on July 4, 1808, it was one of the first shot towers in the United States, with the Jackson Ferry Shot Tower in Wythe County, Virginia possibly predating it by a year or so. It was built near the Delaware River waterfront at Front and Carpenter Streets, just west of Gloria Dei (Old Swedes') Church. History Supplies of lead shot were imported from Europe before the Embargo Act of 1807. Plumbers Thomas Sparks, John Bishop, and James Clement built the tower to take advantage of the limited available supply. At the start of the War of 1812, the federal government became their major customer, buying war munitions, and Quaker John Bishop sold his part of the company to Thomas Sparks.Sparks Shot Tower, 1808 ...

Shot Tower
A shot tower is a tower designed for the production of small-diameter shot balls by free fall of molten lead, which is then caught in a water basin. The shot is primarily used for projectiles in shotguns, and for ballast, radiation shielding, and other applications for which small lead balls are useful. Shot making Process In a shot tower, lead is heated until molten, then dropped through a copper sieve high in the tower. The liquid lead forms tiny spherical balls by surface tension, and solidifies as it falls. The partially cooled balls are caught at the floor of the tower in a water-filled basin.. The now fully cooled balls are checked for roundness and sorted by size; those that are "out of round" are remelted. A slightly inclined table is used for checking roundness. To make larger shot sizes, a copper sieve with larger holes is used. The maximum size is limited by the height of the tower, because larger shot sizes must fall farther to solidify.

Lead Shot
Shot is a collective term for small spheres or pellets, often made of lead. These were the original projectiles for shotguns and are still fired primarily from shotguns and less commonly from riot guns and grenade launchers, although shot shells are available in many pistol calibers in a configuration called "birdshot", "rat-shot", or "snake shot". Lead shot is also used for a variety of other purposes such as filling cavities with dense material for weight/balance. Some versions may be plated with other metals. Lead shot was originally made by pouring molten lead through screens into water, forming what was known as "swan shot", and, later, more economically mass-produced at higher quality using a shot tower. The ''Bliemeister method'' has supplanted the shot tower method since the early 1960s. Manufacture Producing lead shot from a shot tower was pioneered in the late 18th century by William Watts of Bristol who adapted his house on Redcliffe Hill by adding a three-storey t ...

Buildings And Structures In Philadelphia
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artistic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Towers Completed In 1808
A tower is a tall structure, taller than it is wide, often by a significant factor. Towers are distinguished from masts by their lack of guy-wires and are therefore, along with tall buildings, self-supporting structures. Towers are specifically distinguished from buildings in that they are built not to be habitable but to serve other functions using the height of the tower. For example, the height of a clock tower improves the visibility of the clock, and the height of a tower in a fortified building such as a castle increases the visibility of the surroundings for defensive purposes. Towers may also be built for observation, leisure, or telecommunication purposes. A tower can stand alone or be supported by adjacent buildings, or it may be a feature on top of a larger structure or building. Etymology Old English ''torr'' is from Latin ''turris'' via Old French ''tor''. The Latin term together with Greek τύρσις was loaned from a pre-Indo-European Mediterranean language, ...

Historic American Buildings Survey
Heritage Documentation Programs (HDP) is a division of the U.S. National Park Service (NPS) responsible for administering the Historic American Buildings Survey (HABS), Historic American Engineering Record (HAER), and Historic American Landscapes Survey (HALS). These programs were established to document historic places in the United States. Records consist of measured drawings, archival photographs, and written reports, and are archived in the Prints and Photographs Division of the Library of Congress. Historic American Buildings Survey In 1933, NPS established the Historic American Buildings Survey following a proposal by Charles E. Peterson, a young landscape architect in the agency. It was founded as a constructive make-work program for architects, draftsmen and photographers left jobless by the Great Depression. It was supported through the Historic Sites Act of 1935. Guided by field instructions from Washington, D.C., the first HABS recorders were tasked with documen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shotgun Shell
A shotgun shell, shotshell or simply shell is a type of rimmed, cylindrical (straight-walled) cartridges used specifically in shotguns, and is typically loaded with numerous small, pellet-like spherical sub- projectiles called shot, fired through a smoothbore barrel with a tapered constriction at the muzzle to regulate the extent of scattering. A shell can sometimes also contain only a single large solid projectile known as a slug, fired usually through a rifled slug barrel. The hull usually consists of a paper or plastic tube often covered at the base by a metallic head cover which retains a primer, and the shot charge is typically contained by a wadding/sabot inside the case. The caliber of the shotshell is known as its gauge. The projectiles are traditionally made of lead, but other metals such as steel, tungsten and bismuth are also used due to restrictions on lead, or for performance reasons such as achieving higher shot velocities by reducing the mass of the sh ...

Phoenix Shot Tower
The Phoenix Shot Tower, also known as the Old Baltimore Shot Tower, is a red brick shot tower, tall, located near the downtown, Jonestown (also known later as Old Town), and Little Italy communities of East Baltimore, in Maryland. When it was completed in 1828 it was the tallest structure in the United States. The tower was originally known as the "Phoenix Shot Tower", then the "Merchants' Shot Tower", and now is also sometimes called the "Old Baltimore Shot Tower". It is the only surviving shot tower among four that existed in Baltimore, and was designated a National Historic Landmark on November 11, 1971. It was designated as a local Baltimore City Landmark on October 14, 1975. The Shot Tower lends its name to the nearby Shot Tower/Market Place station on the Baltimore Metro subway system's northeast line. Additionally, the original Baltimore Bullets were named in honor of its role in producing shot, as was the team that is now known as the Washington Wizards. Design Th ...

Interstate 95 In Pennsylvania
Interstate 95 (I-95) is a major north-south Interstate highway that runs along the East Coast of the United States from Miami, Florida, north to Houlton, Maine. In the state of Pennsylvania, it runs from the Delaware state line near Marcus Hook in Delaware County northeast to the Delaware River–Turnpike Toll Bridge at the New Jersey state line near Bristol in Bucks County. From the Delaware state line to exit 40, the route is known by many as the Delaware Expressway but is officially named the Vietnam Veterans Memorial Highway. North of exit 40, I-95 follows the easternmost portion of the Pennsylvania Turnpike; this portion of road is not signed as part of the turnpike. I-95 parallels its namesake Delaware River for its entire route through the city of Philadelphia and its suburbs. It is a major route through the city and the metropolitan Delaware Valley, providing access to locally important landmarks such as Subaru Park, Philadelphia International Airport, the South Phi ...

American Civil War
The American Civil War (April 12, 1861 – May 26, 1865; also known by other names) was a civil war in the United States. It was fought between the Union ("the North") and the Confederacy ("the South"), the latter formed by states that had seceded. The central cause of the war was the dispute over whether slavery would be permitted to expand into the western territories, leading to more slave states, or be prevented from doing so, which was widely believed would place slavery on a course of ultimate extinction. Decades of political controversy over slavery were brought to a head by the victory in the 1860 U.S. presidential election of Abraham Lincoln, who opposed slavery's expansion into the west. An initial seven southern slave states responded to Lincoln's victory by seceding from the United States and, in 1861, forming the Confederacy. The Confederacy seized U.S. forts and other federal assets within their borders. Led by Confederate President Jefferson Davis, ...

War Of 1812
The War of 1812 (18 June 1812 – 17 February 1815) was fought by the United States of America and its indigenous allies against the United Kingdom and its allies in British North America, with limited participation by Spain in Florida. It began when the United States declared war on 18 June 1812 and, although peace terms were agreed upon in the December 1814 Treaty of Ghent, did not officially end until the peace treaty was ratified by Congress on 17 February 1815. Tensions originated in long-standing differences over territorial expansion in North America and British support for Native American tribes who opposed US colonial settlement in the Northwest Territory. These escalated in 1807 after the Royal Navy began enforcing tighter restrictions on American trade with France and press-ganged men they claimed as British subjects, even those with American citizenship certificates. Opinion in the US was split on how to respond, and although majorities in both the House and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Religious Society Of Friends
Quakers are people who belong to a historically Protestant Christian set of denominations known formally as the Religious Society of Friends. Members of these movements ("theFriends") are generally united by a belief in each human's ability to experience the light within or see "that of God in every one". Some profess a priesthood of all believers inspired by the First Epistle of Peter. They include those with evangelical, holiness, liberal, and traditional Quaker understandings of Christianity. There are also Nontheist Quakers, whose spiritual practice does not rely on the existence of God. To differing extents, the Friends avoid creeds and hierarchical structures. In 2017, there were an estimated 377,557 adult Quakers, 49% of them in Africa. Some 89% of Quakers worldwide belong to ''evangelical'' and ''programmed'' branches that hold services with singing and a prepared Bible message coordinated by a pastor. Some 11% practice ''waiting worship'' or ''unprogrammed wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
