Dave Lennox
David Lennox (April 15, 1855 – February 15, 1947) was an American inventor and businessman. A furnace manufacturing business he founded in 1895 in Marshalltown, Iowa evolved into what is today known as Lennox International, a global corporation specializing in air conditioning, heating, and commercial refrigeration. Lennox helped to develop what has been described as the first riveted-steel furnace in 1895. His contributions to furnace design have been described as significant steps forward in durability and efficiency from the cast iron furnaces commonly in use near the end of the 19th century. Early life Born in Detroit, Michigan on April 15, 1855, Lennox was the son of a railroad mechanic. His family moved to Aurora, Illinois shortly before the American Civil War, where Lennox’ father enlisted in the Union Army. His father was killed in 1863 at the battle of Champion Hill, east of Vicksburg, Mississippi. The surviving Lennox family moved to Chicago in 1865, where Len ...

Marshalltown, Iowa
Marshalltown is a city in and the county seat of Marshall County, Iowa, United States, located along the Iowa River. It is the seat and most populous settlement of Marshall County and the 16th largest city in Iowa, with a population of 27,591 at the 2020 census. Marshalltown is home to the Iowa Veterans Home and Marshalltown Community College. History Henry Anson was the first European settler in what is now called Marshalltown. In April 1851, Anson found what he described as “the prettiest place in Iowa.” On a high point between the Iowa River and Linn Creek, Anson built a log cabin. A plaque at 112 West Main Street marks the site of the cabin. In 1853 Anson named the town Marshall, after Marshall, Michigan, a former residence of his. The town became Marshalltown in 1862 because another Marshall already existed in Henry County, Iowa (In 1880, Marshall's name changed to Wayland). With the help of Potawatomi chief Johnny Green, Anson persuaded early settlers to stay in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oskaloosa, Iowa
Oskaloosa is a city in, and the county seat of, Mahaska County, Iowa, United States. In the late nineteenth and early twentieth century, Oskaloosa was a national center of bituminous coal mining. The population was 11,558 in the 2020 U.S. Census, an increase from 10,938 in 2000. History Oskaloosa derives its name from Ouscaloosa who, according to town lore, was a Creek princess who married Seminole chief Osceola. A local tradition was that her name meant "last of the beautiful." (This interpretation of "last of the beautiful" is not correct. "Oskaloosa" in the Mvskoke-Creek language means "black rain," from the Mvskoke words "oske" (rain) and "lvste" (black). "loosa" is an English corruption of the Mvskoke word "lvste". See for example the Wikipedia entry for Tuskaloosa, eponym of the town of Tuscaloosa, Alabama. In addition the Mvskoke word "Ouscaloosa" means "Black Water"). The first European-American settlers arrived in 1835, led by Nathan Boone, youngest son of fronti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

People From Marshalltown, Iowa
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...

Indoor Air Quality
Indoor air quality (IAQ) is the air quality within and around buildings and structures. IAQ is known to affect the health, comfort, and well-being of building occupants. Poor indoor air quality has been linked to sick building syndrome, reduced productivity, and impaired learning in schools. Common pollutants of indoor air include: Secondhand tobacco smoke, air pollutants from indoor combustion, radon, molds and other allergens, carbon monoxide, volatile organic compounds, legionella and other bacteria, asbestos fibers, carbon dioxide, ozone and particulates. Source control, filtration, and the use of ventilation to dilute contaminants are the primary methods for improving indoor air quality in most buildings. Determination of IAQ involves the collection of air samples, monitoring human exposure to pollutants, collection of samples on building surfaces, and computer modelling of air flow inside buildings. IAQ is part of indoor environmental quality (IEQ), which includes IAQ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Patent
A patent is a type of intellectual property that gives its owner the legal right to exclude others from making, using, or selling an invention for a limited period of time in exchange for publishing an enabling disclosure of the invention."A patent is not the grant of a right to make or use or sell. It does not, directly or indirectly, imply any such right. It grants only the right to exclude others. The supposition that a right to make is created by the patent grant is obviously inconsistent with the established distinctions between generic and specific patents, and with the well-known fact that a very considerable portion of the patents granted are in a field covered by a former relatively generic or basic patent, are tributary to such earlier patent, and cannot be practiced unless by license thereunder." – ''Herman v. Youngstown Car Mfg. Co.'', 191 F. 579, 584–85, 112 CCA 185 (6th Cir. 1911) In most countries, patent rights fall under private law and the patent holder mus ...

Marshalltown Company is a privately held American manufacturer of construction tools and equipment used for archaeology, asphalt, concrete, drywall, EIFS, flooring, masonry, painting, plastering, stucco, tile, and wallpaper based in Marshalltown, Iowa. Marshalltown, founded in 1890, was one of the top producers of construction tools and equipment in the world, including the Marshalltown pointing trowel, a tool often used by American archaeologists. Company history The origins of Marshalltown can be traced back to the American inventor and entrepreneur Dave Lennox. While working in his machine shop in the mid-1880s in Marshalltown, Iowa, Mr. Lennox received a visit from a stonemason who asked him to make a better plastering trowel while working on the construction site of the Marshall County Courthouse. Using the mason’s criteria, Mr. Lennox forged the trowel and delivered it to the worker, who then showed it off to other masons in the area. Those masons considered the new ...

Barbed Wire
A close-up view of a barbed wire Roll of modern agricultural barbed wire Barbed wire, also known as barb wire, is a type of steel fencing wire constructed with sharp edges or points arranged at intervals along the strands. Its primary use is the construction of inexpensive fences, and it is also used as a security measure atop walls surrounding property. As a wire obstacle, it is a major feature of the fortifications in trench warfare. A person or animal trying to pass through or over barbed wire will suffer discomfort and possibly injury. Barbed wire fencing requires only fence posts, wire, and fixing devices such as staples. It is simple to construct and quick to erect, even by an unskilled person. The first patent in the United States for barbed wire was issued in 1867 to Lucien B. Smith of Kent, Ohio, who is regarded as the inventor. Joseph F. Glidden of DeKalb, Illinois, received a patent for the modern invention in 1874 after he made his own modifications to previous ...
