Английская Википедия:Carlisle & Finch
Шаблон:Short description Шаблон:Good article Шаблон:Infobox company Carlisle & Finch is a manufacturer of nautical equipment founded in 1893 or 1894 in Cincinnati, Ohio, where, Шаблон:As of, it still has its headquarters. The company's main products through its entire history have been searchlights, mostly for marine applications. It was also known for navigation beacons used by airports and lighthouses.
In addition, it was known as a producer and innovator of electric toy trains in the early years of the company. Other early products included electric generators (powered either by water pressure or by gasoline engine), and various electric-powered appliances.
Corporate history
The company began as a branch office of General Electric at 182–84 Elm Street, Cincinnati, Ohio, where Robert S. Finch and Morten Carlisle were employed. Work included repairing electrical machinery, such as armatures, transformers, and arc lamps.[1][2]
In 1893 or 1894 (sources differ), Carlisle and Finch purchased the shop from General Electric, intending to continue the repair business and branch out into manufacturing.[1][2][3] The new company was incorporated on April 17, 1897, with Carlisle serving as president.[1][4] The same year, they introduced their first new products, a searchlight based on the carbon arc principle, and a toy train, which also used a carbon arc for its headlight.[5] As the company grew, they added gasoline engines.[1][6][7]
Carlisle sold his share of the business to Finch on August 4, 1926. Brent S. Finch, Robert's son, was named president, and the company started concentrating entirely on its searchlight business. After World War II, Brent R. Finch (son of Brent S.) was hired, at which point three generations of Finches were simultaneously employed by the company. Шаблон:As of, a fourth-generation leads the company, with brothers Kurtis B. Finch and Garth S. Finch serving as president and senior vice president, respectively.[1]
A subsidiary company, C&F Polishing, provides metal polishing and restoration services.[8]
Toy trains
One of Carlisle & Finch's earliest products was electric toy trains, and they were the first company to manufacture them in America.[9] The wood and metal trains entered the marketplace Шаблон:Circa. They were approximately Шаблон:Convert tall and ran on metal track with rails Шаблон:Convert apart, known as 2 gauge.[4]
Other American companies made toy trains before Carlisle & Finch. Edward Ives, for example, had a factory in Plymouth, Connecticut, in 1896. These other makers used wind-up clockworks, steam, electric batteries, or overhead wires to power the cars. Carlisle & Finch's innovation was to use the two rails as electrical conductors[10] although this technology had been demonstrated as early as 1851 by Thomas Hall.[11]
In 1897, they made a train set with a 4-wheel coal mining locomotive, three coal cars, two zinc-carbon elements, and a can of chromite. The locomotive included a switch for starting and reversing, and was powerful enough to pull the three loaded cars up a grade. That same year, they also made an "electric railway with double truck car" set, with a car running on two 4-wheel trucks. It was Шаблон:Convert long, Шаблон:Convert high, and Шаблон:Convert wide, and made of polished brass with iron wheels. It had two motors and could run at Шаблон:Convert. Both sets included Шаблон:Convert of Шаблон:Convert gauge track.[12]
Searchlights
When World War I started, production was shifted entirely to searchlights, to aid the war effort. The U.S. Government was a major purchaser, with additional large orders from Greece, Spain, Norway, and Russia.[1][13] By 1917, it was one of the few companies worldwide producing searchlights, and had supplied a large proportion of the searchlights then in use by the United States and other countries. They produced a line of commercial searchlights, and also specialized in navy and military designs. Units were built with Шаблон:Convert diameters, and Шаблон:Convert ranges. Current draw was 10 to 200 amps.[14]
The earliest models used a carbon arc for the light source. Other companies had previously built carbon arc searchlights, but Carlisle & Finch added the innovation of mounting the carbon electrodes horizontally on the beam axis. The tip of the positive carbon faced the reflector, maximizing the amount of light reflected, and spacing of the carbons was adjusted by motorized screw-feed mechanisms.[15] A manually-activated screw moved the entire mechanism forward and backward, positioning the arc at the mirror's focal point. A pair of carbons had a lifetime of about seven hours.[16]
The company introduced Xenon arc searchlights in the 1960s.[17] LED models followed in 2019.[18]
Шаблон:Multiple imageDistinct from searchlights, Carlisle & Finch also produced rotating beacons in the DCB (Directional Code Beacon) series starting around 1950.[19] These project a narrow light beam. The light rotates, causing it to appear to flash from the viewpoint of a distant observer. These were originally used as aerodrome beacons, but in the 1990s, the U.S. Coast Guard adopted them for use in lighthouses, replacing existing Fresnel lenses. Models included DCB-24 with a Шаблон:Convert diameter, DCB-224 with two such lights, and DCB-36 with a Шаблон:Convert diameter.[20]
Шаблон:As of the DCB-24 and DCB-224 were the standard optics used in landfall lights (the first lights seen when approaching the coast from the open sea).[21] They have a nominal range of Шаблон:Convert depending on the rotation speed and whether a colored cover was installed. They could operate in winds up to Шаблон:Convert, and included an automatic lamp changer.[22]
Other products
In 1897, Carlisle & Finch offered a hand-powered dynamo, capable of lighting a ten candle power, ten volt incandescent bulb, or to run several electrical toys simultaneously. They also offered a water-powered version, which produced a similar amount of electrical power from a water faucet supplying Шаблон:Convert of pressure and could be used with as low as Шаблон:Convert.[12]
In 1912, they introduced a dynamo driven by a directly connected gasoline motor. The engine was Шаблон:Convert, and the dynamo produced 42 volts at 15 amps. A belt pulley was included for driving an external load. The entire assembly weighed Шаблон:Convert.[23]
In 1923, a clothes dryer was introduced. The device used a wire mesh drum rotated by an electric motor. Air heated by either gas or steam was forced through the drum, with the temperature controlled by a thermostat. The machine was Шаблон:Convert deep, Шаблон:Convert wide, Шаблон:Convert tall, and weighed Шаблон:Convert.[24]
