Yefim and Miron Cherepanov

In 1810s Yefim built a progressive machine-building plant, equipped with a full range of innovative metal-cutting lathes (such as screw-cutters, gear-cutting serrating machines and others).

From 1822 until his death, Yefim was chief mechanic for all the factories in the town of Nizhny Tagil.

The Cherepanovs significantly improved the machinery that had been used in blast-furnace and gold-mining industries, iron and copper works, sawmills, and flourmills.

The most interesting aspect of the Cherepanovs' work were steam engines which they tried to introduce into industrial production.

[2] Despite the successful performance and operation of their locomotives, the Cherepanovs' invention found no support outside the factory and, subsequently, horse traction replaced their steam locomotives.
