Adjustable Spanner Vol II (Geesin Ron)(Pevná vazba)

The Adjustable Spanner Volume II gathers together revelatory information arising from Ron Geesin’s first book, and combines it with further detailed analysis of manufacturers and biographical details of inventors. Described with warmth, detailed knowledge and a dash of humour, and set against the backdrop of parallel developments of the Industrial Revolution, this book brings the enthusiast up to date with continued attempts at design improvements to this iconic absurdity. Celebrating the global influence of Richard Clyburn’s transverse rack and worm design which set the modern standard for adjustable spanners and concluding with an overview of how the adjustable spanner is now manufactured and used worldwide, this book will be an invaluable asset to bookshelves of both the collector and the industrial historian.
