Sonestown Covered Bridge
The Sonestown Covered Bridge is a covered bridge over Muncy Creek in Davidson Township, Sullivan County, Pennsylvania built around 1850. It is long and was placed on the National Register of Historic Places (NRHP) in 1980. ''Note:'' This includes It is named for the nearby unincorporated village of Sonestown in Davidson Township, and is also known as the Davidson Covered Bridge. It was built to provide access to a grist mill which operated until the early 20th century. Pennsylvania had the first covered bridge in the United States and has the most of any state in the 21st century. In most places, they were a transition between stone and metal bridges, with the roof and sides protecting the wooden structure from weather. The Sonestown bridge is a Burr arch truss type with a load-bearing arch sandwiching multiple vertical king posts for strength and rigidity. The bridge construction is cruder than the other two surviving covered bridges in Sullivan County, with each Burr ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
TopoQuest
TopoQuest is a free web mapping service built on Open-source software, open source software that provides internet-based topographic maps for most of the United States. The site is one of three internet services used by Wikipedia for providing topographic maps. It arose to prominence in May 2008 after TopoZone through its new trails.com owners required payment for access to its maps. TopoQuest map links are the same as Topozone's except for the difference in the domain. It is operated by Ryan Niemi in Klamath Falls, Oregon. History Niemi first experimented with a mapping program in July 2001 as a Linux, PHP and MySQL alternative to Microsoft's TerraServer-USA topographic mapviewer. The domain was registered at Go Daddy to Sunset Dynamics on August 10, 2004. However Niemi did not aggressively develop the website because of the success of Topozone. After Topozone started the for pay business model on April 8, 2008, Niemi made updates to get the website to match the Topozone URL ...

Hillsgrove Covered Bridge
The Hillsgrove Covered Bridge is a Burr arch truss covered bridge over Loyalsock Creek in Hillsgrove Township, Sullivan County, in the U.S. state of Pennsylvania. It was built c. 1850 and is long. In 1973, it became the first covered bridge in the county to be placed on the National Register of Historic Places (NRHP). The bridge is named for the township and nearby unincorporated village of Hillsgrove, and is also known as Rinkers Covered Bridge for an adjoining farm. Pennsylvania had the first covered bridge in the United States, and has had the most such bridges since the 19th century. They were a transition between stone and metal bridges, with the roof and sides protecting the wooden structure from the weather. The Hillsgrove bridge has load-bearing Burr arches sandwiching multiple vertical king posts on each side, for strength and rigidity. It was built by Sadler Rodgers, who also constructed the nearby Forksville Covered Bridge in the same year, with a similar design. ...

Forksville Covered Bridge
The Forksville Covered Bridge is a Burr arch truss covered bridge over Loyalsock Creek in the borough of Forksville, Sullivan County, in the U.S. state of Pennsylvania. It was built in 1850 and is in length. The bridge was placed on the National Register of Historic Places in 1980. The Forksville bridge is named for the borough it is in, which in turn is named for its location at the confluence or "forks" of the Little Loyalsock and Loyalsock Creeks. Pennsylvania had the first covered bridge in the United States and the most such bridges in both the 19th and 21st centuries. They were a transition between stone and metal bridges, with the roof and sides protecting the wooden structure from weather. The Forksville bridge is a Burr arch truss type, with a load-bearing arch sandwiching multiple vertical king posts, for strength and rigidity.

Arch
An arch is a vertical curved structure that spans an elevated space and may or may not support the weight above it, or in case of a horizontal arch like an arch dam, the hydrostatic pressure against it. Arches may be synonymous with vaults, but a vault may be distinguished as a continuous arch forming a roof. Arches appeared as early as the 2nd millennium BC in Mesopotamian brick architecture, and their systematic use started with the ancient Romans, who were the first to apply the technique to a wide range of structures. Basic concepts An arch is a pure compression form. It can span a large area by resolving forces into compressive stresses, and thereby eliminating tensile stresses. This is sometimes denominated "arch action". As the forces in the arch are transferred to its base, the arch pushes outward at its base, denominated "thrust". As the rise, i. e. height, of the arch decreases the outward thrust increases. In order to preserve arch action and prevent collapse ...

Structural Engineering
Structural engineering is a sub-discipline of civil engineering in which structural engineers are trained to design the 'bones and muscles' that create the form and shape of man-made structures. Structural engineers also must understand and calculate the stability, strength, rigidity and earthquake-susceptibility of built structures for buildings and nonbuilding structures. The structural designs are integrated with those of other designers such as architects and building services engineer and often supervise the construction of projects by contractors on site. They can also be involved in the design of machinery, medical equipment, and vehicles where structural integrity affects functioning and safety. See glossary of structural engineering. Structural engineering theory is based upon applied physical laws and empirical knowledge of the structural performance of different materials and geometries. Structural engineering design uses a number of relatively simple structural c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Schuylkill River
The Schuylkill River ( , ) is a river running northwest to southeast in eastern Pennsylvania.

In 1682, William Penn chose the left bank of the confluence upon which he founded the planned city of Philadelphia on lands purchased from the native Delaware nation. It is a designated Pennsylvania Scenic River, and its whole length was once part of the Delaware people's southern territories.

Sonestown Covered Bridge 16
Sonestown is a former unincorporated village in what is now Davidson Township, Sullivan County, in the U.S. state of Pennsylvania. History and notable features In 1843, George Sones built a sawmill and founded Sonestown, an unincorporated village within what is now Davidson Township in Sullivan County, Pennsylvania. This occurred before Sullivan County was formed from part of Lycoming County on March 14, 1847. ''Note'': Davidson Township was formed in 1833 from part of Shrewsbury Township while both were still part of Lycoming County. A bridge was then erected in 1850. During the late nineteenth century, Sonestown "boomed like crazy" as the county's lumber industry grew. The village was home, at that time, to a plant that manufactured staves for barrel making. The Eagles Mere Railroad (1892-1928), a narrow-gauge line providing rail access to the resort town of Eagles Mere, also had its southern terminus in Sonestown. Although the town had a clothespin factory that operated rou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Clothespin
A clothespin (US English), or clothes peg (UK English) is a fastener used to hang up clothes for drying, usually on a clothes line. Clothespins come in many different designs. Design During the 1700s laundry was hung on bushes, limbs or lines to dry but no clothespins can be found in any painting or prints of the era. The clothespin for hanging up wet laundry only appears in the early 19th century supposedly patented by Jérémie Victor Opdebec. This design does not use springs, but is fashioned in one piece of wood, with the two prongs part of the peg chassis with only a small distance between them—this form of peg creates the gripping action due to the two prongs being wedged apart and thus squeezing together in that the prongs want to return to their initial, resting state. This form of peg is often fashioned from plastic, or originally, wood. In England, clothes-peg making used to be a craft associated with the Romani people, commonly known by the term “gypsy”, wh ...
