9765 - Profile No 4 - Tyrer's DUPLEX escapement : a century of use
PENNEY DavidA short historical introduction is followed by an overview of the escapements distinctive action and all the variations that can be found, starting with the earliest and rarest double-wheel form as given in the short description printed in the Patent Abridgements of 1858, referring to Tyrer’s Patent of January 1782. This was the same year as John Arnold and Thomas Wright (for Thomas Earnshaw) took out patents for their spring-detent escapements. NB: A surviving example of Tyrer’s original escapement has never previously been shown in print.
The fourth in a series of Horological Profiles aimed primarily at watch owners, collectors, dealers, auctioneers and museum staff, as well as anyone with a passing interest in the subject of antiquarian horology in general. The aim is to provide the latest and most up-to-date information regarding watches of all types. This includes both technical and decorative features and I welcome feedback that will either correct or enlarge on their content.
The size of the booklets and their subsequent limitations is intended. I have no wish to produce publications that are too large or too annoyingly cumbersome to use, and I trust it will be a pleasure to consult these Profiles either at home or on the road. Issues can of course be bound for added durability if so wished.
As a professional researcher within the field of the history of technology, primarily within antiquarian horology, it has become clear that there is a great deal of missing and incorrect information in the available resources. I trust those booklets will help place what are often the most wonderful objects within their deserved historical framework. Watch and clock making has occupied some of the greatest minds (technical, artistic and scientific) over the last 500 or so years and the best work of any period really does deserve to be better understood. In publishing these Profiles, I trust it can be better appreciated.
