Interactive engineering reference
An interactive companion to Gardner Dexter Hiscox’s 1,800 Mechanical Movements, Devices and Appliances
See the movement. Understand the mechanism. Test the idea.
Gardner Dexter Hiscox’s Mechanical Movements, Powers, Devices and Appliances remains a remarkable catalogue of practical mechanical ideas. This FIRGELLI interactive companion connects those historical mechanisms with modern animations, engineering calculators and application notes.
The 1903 tenth edition describes itself as illustrated by 1,800 engravings. Its numbered catalogue runs through item 1,649 because some numbered entries contain more than one engraving. This hub also includes FIRGELLI mechanism and system articles that are not part of the original book, giving designers one searchable place to explore both the historical reference and related modern engineering topics.
Where FIRGELLI expands, interprets or corrects a historical mechanism, the modern explanation is identified as our reconstruction. Calculators show their variables, units and assumptions so the result can be checked rather than treated as a black box.
