Object StatementDrawing, the Imperial Bank Mint at St Petersburg, section showing a Boulton and Watt steam engine and machinery for making silver coins, paper / ink, made by Alexey Nikolaevich Olenin and the architect Baboshin, St Petersburg, Russia, 1796-1798
Physical DescriptionA pen and wash drawing of a Boulton and Watt steam engine and machinery for making silver coins. The drawing is an elevation showing cross sections of the building and of the boiler and engine within it. It also shows four men, one alone and the others in a group.
The boiler is of the haystack type, with a fire below and water inside. A water delivery pipe and valve are shown, as is a pipe for conveying steam to the engine.The piston is shown inside the engine's cylinder, and the separate condenser and air pump are also shown in section. The engine has a parallel motion mechanism connecting the piston rod and beam, a timber beam, timber connecting rod, and sun and planet gears. The drive wheel is shown in front of the flywheel, and a bevel gear engaging with the drive wheel sits in front of it, driving a machine that has a crank and flywheel. Also in front of the engine, and driven via a wheel that appears to sit behind the drive wheel, is a mill for rolling metal to the thickness required for coinage. Other machinery is visible behind the engine.
The title of the drawing is written in the top right corner. There is also Russian text at top left. This is probably the title repeated in Russian. Additional text can be seen in the bottom right and in Russian in the bottom left. At the bottom centre of the drawing is written 'two 10th of an inch per foot', which indicates that the scale is 1:60. All writing is in script.
The letter A in red appears at either side of the drawing. The same letters would also have appeared on a plan of the building, with a line between them to show where this section is located. The letters R and I also appear on the drawing. Indeed, a plan of the proposed mint labelled with these letters does exist, and it is reproduced on page 84 of Richard Doty's book, 'The Soho Mint and the Industrialization of Money' (Smithsonian Institution, 1998).
The paper is watermarked.
MarksHandwritten in top right corner 'Section of the Steam Engine / for the Silver Coinage'. Russian script can be seen in the top left corner.
'No 2' can be seen in the top centre of the drawing and 'two 10ths of an inch per foot' is written in the bottom centre of the drawing.
Text at the bottom right reads 'Delineated by A Olenin Esq, Drawn by the arch. Baboshin'. The text at bottom left probably repeats this in Russian.
Watermark on paper reads 'Smyth 1796'.
