"Coin Press No. 1 arriving from the San Francisco Mint. Judge Clark J. Guild ( founder of the Nevada State Museum in 1939) is pointing at the press on the front steps of the Museum's entrance. The press was purchased from the U.S. Mint for $225 by the Museum Board. Coin Press No. 1 was the original press sent to the Carson City Mint when it opened in 1870. When minting operations ended in the 1890s it was sent to the Philadelphia Mint in 1899 where it was remodeled to operate by electric power. In 1945 it was sent to the San Francisco Mint and renumbered "5" to correspond with its place in the coining department there. It was returned to Carson City in 1958".

As was the custom of the day, the coin press was painted with a large number "1" to signify the first press located in the coiners department. On February 11, 1870, Coin Press No. 1 struck the first coin, a Seated Liberty Dollar bearing the soon to be famous "CC" mintmark.

More precisely:
1. tube - the
accumulator with a strictly horizontal workpieces position.
The same press at the mint in Mexico (1888).
Here tube – accumulator has a curved shape.
To load the large-diameter coins , there is applied another embodiment of the constructive solutions of the tube.
The feeder tube ended a cruel problem: whoever put the blanks in the press (often children) was always in danger of losing fingers. The tube created distance between fingers and press.

Fingers working in the process of minting coins, are safe.
Nicely done Filat & welcome ! :)
Going through the tray and tube - accumulator preform gets into the zone of forks system of automatic feed workpieces into the zone of coinage.
Next (see images):
1. Fork delivers a preform in zone coinage, pushing forward previously minted coin;
2. Fork has filed preform for stamping and went back behind the new workpiece;
3. The process of coinage.

Quote (Russian language):
"В 1775-м году Мэтью Болтон познакомился с великим английским физиком и изобретателем Джеймсом Ваттом. В голове Ватта уже созрела мысль об изобретении нового двигателя, работающего на энергии пара - идея возникла у него в 1774-м году, но реально воплотилась в жизнь спустя 10 лет, в 1784-м, когда двигатель был официально запатентован. После того, как Ватт поделился своими идеями с Болтоном, они сразу же стали компаньонами.
И Болтон, и Ватт решили расширить производство и основать монетный двор. Сначала на нём были установлены монетные прессы старого образца, а сам двор находился ещё не в Soho. В 1786-м году Болтон выиграл подряд на 100 тонн монет для британской Восточно-африканской компании. Монеты, отчеканенные на этом временном монетном дворе, предназначались для обращения в Бенкулу (Bencoolen) на Суматре. В 1786 - 1788-х годах Болтон чеканил монеты для Сьерра Леоне. А в 1786-м году монетный двор Болтона посетила российская императрица Екатерина II и закупила оборудование Болтона и Ватта для монетного двора в Санкт - Петербурге, а монетный двор получил заказ на изготовление монет для российской Восточно-африканской компании (напомню, что в собственности Российской Империи находился остров Мадагаскар). Но это не были первые монеты, отчеканенные на энергии пара, умело использованной Джеймсом Ваттом! Первые монеты, отчеканенными на паровом монетном станке, былиотчеканены в Soho летом 1789-го года. Это были токены для Roe & Company, они предназначались для расчётов между клиентами этой компании".
Rough translation:
QuoteI think that in 1775 , the year Matthew Boulton met the great English physicist and inventor James Watt, Watt was already thinking about inventing a new engine running on steam power - the idea came to him in the year 1774, but it took practical shape only after 10 years , in 1784, when the engine was officially patented. After Watts shared his ideas with Bolton, they immediately became partners.
Bolton and Watt decided to expand production and to establish a mint. First, an old-fashioned screw press mint was established, the factory was not yet in Soho. In the year 1786, Bolton won a contract for 100 tons of coins for the British East Africa Company. Coins minted at this time mint were intended for circulation in Benkulu (Bencoolen) in Sumatra. In the years 1786 - 1788 Bolton minted coins for Sierra Leone. And in 1786 , Bolton's Mint was visited by the Russian Empress Catherine II, who purchased equipment for a Bolton and Watt mint in St. - Petersburg. The Mint was commissioned to manufacture coins for Russian East African Company (remember that the Russian Empire owned the island of Madagascar). But these were not the first coins minted by a steam engine, skilfully made by James Watt! The first coins minted on a steam machine press were made in Soho in the summer of 1789 . These were tokens for Roe & Company, intended for payments of clients of the company.

U.S. Mint, viewed from the Mississippi River levee, c. (1905)
Mines around Nevada were producing rich precious metal ore, difficult and dangerous to transport. It made sense to convert it into coins locally. Work on the Carson City mint started in 1866. In 1870, the mint started working, producing quarters, halves, dollars and gold. In 1876, production was at its largest, with almost 16 million coins, half of which dimes. After 1878, only silver dollars and gold was struck, on average around 1.5 million coins a year, mostly dollars. Mintage stopped in 1893 and the building was turned into an assay office. The office was closed in 1933 and the building abandoned.
In 1939, the government permitted the State of Nevada to turn the building into a State Museum. Bad timing. It took until the end of the second world war, before renovation and extension was completed. In 1941, visitor capacity was around 500 000, but there were only 1775 visitors. However, through private initiative and financing, the idea was saved. The map and picture date from around 1970. The museum is marked J, on Robinson and Curry.
The press (number 5) is a major exhibit. It was made in 1868 by Morgan and Orr. It started (silver dollar) production in Carson City in 1870 and went through a major revision by the Virginia & Truckee railroad shop in 1878. It was idle when the mint was closed in 1893, until it was shipped to the Philadelphia mint in 1899. Steam was replaced by electricity in 1930, giving the press a new lease of life. In 1945, it was moved to San Francisco to replace number 1, which was sold for scrap. It returned to Carson City in 1958 as a museum exhibit, but it is still capable of striking coins and medals. At some time after 1970, its number was fraudulently changed from 5 to 1, though.

"The tall smoke stack of the smelting furnace and the loading docks at the rear of the New Orleans Mint dominate this 1866 stereoview by Blessing. In 1838, shortly after the discovery of gold in the South, the New Orleans Mint opened its doors for business. Its convenient location near the Mississippi River made it easy to turn precious metal from southern mines, foreign ports, and later, California, into coinage for a growing nation.
The mint operated from 1838 to 1861 and 1879 until 1909, when it closed its doors for good. "
