A PART-BUILT SLAVE MOVEMENT FOR AND EXPERIMENTAL ELECTROMAGNETIC PENDULUM REGULATORLESLIE PATON, LONDON, DATED 1992The slave mechanism mostlyplete and utilising Synchronome regulator-type motionwork incorporating wheel work set between spotted rectangular plates controlled by an electromagnet and detent releasing a ratchet wheel one tooth at a time, with electrical circuitry and transformer set on an additional plate behind, the front with falseplate and 8 inch engraved brass dialposed in regulator format with subsidiary minute over Roman numeral hour dials and engraved FREE, PENDULUM, Paton's Principle, London, 1992 INV. 2 MINUTE, IMPULSE to centre, within outer minute track incorporating Arabic five minute annotations, set into a chrome-plated surround applied to a cylindrical brhed brass case; with an iplete master clock mechanism with A-shaped cast in aluminium alloy with wide-jaw spension bracket over pierced plate fitted with electromagnetic coils opposing ratchet escape wheel and fitted with most of the related detents and levers for operation with a pendulum (not present), (2).The slave movement 22cm (8.625ins) diameter, 7,5cm (3ins) deep.Leslie Paton was born in 1929 and who as a teenager in his spare time learnt the skill of dial engraving from a highly experienced specialist engraver working in Clerkenwell. After serving his National Service in the Royal Signals Leslie Paton went to work at Plymouth Dockyard servicing and repairing s clocks, chronometers and other timepieces. In addition to this he undertook some contract work to maintain 'clocking-in' clocks and related factory timepieces which sparked his interest in electrical horology. After moving back to London he retrained as a draughtsman and worked for apany in Enfield up until his retirement. During his retirement Paton became actively involved in the Electrical Horology Group of the Antiquarian Horological Society and presented lectures relating to steels and their e in clockmaking. His particular interest was for high precision electro-magnetic regulators which led him to the research of the Rsian horologist F.M. Fedchenko whose work on Isochrono Pendulum Spension were the subject of an article published by Paton in the 1990's. The current lot is the start of a long-term project that Leslie Paton was undertaking to create his own high-precision free-pendulum timepiece most likely incorporating an isochrono pendulum spension based on Fedchenko's principles. The Dial engraved by him is testament to the skills learnt as a teenager and this would have appeared to be his starting point for the project. Sadly Leslie Paton was unable to progress with his vision as he developed an aggressive cancer and passed away in 1998 aged 69. Although the current lot appears to only be the start of a long-term project it will hopefully spark the interest of someone who shares a similar interest and would like to take it on and see Leslie Paton's vision throu
