Demonstration apparatus (detail)
Add to album
This is a detail of apparatus, designed by James Ferguson and made around 1800. The apparatus was retailed by W. & S. Jones, scientific instrument makers based in London. It was designed to show the equilibrium between the weight of a wedge and the resistance of two cylinders.
The wooden base has an inset ivory plate marked 'W. & S. Jones,/ No 30 Holborn / London'.
William (1762-1832) and Samuel (1770-1859) Jones were the only children of John Jones, a London instrument maker. Through the acquisition of the copyright of George Adams' textbooks in 1797, and possibly those of Benjamin Martin in 1782, the Jones brothers were able to advertise a huge variety of instruments and apparatus for sale between 1793 and 1855. A lucrative part of their market was located in North America.
