Skeleton Regulator By R N U Pickering
Rowland Neville Umfreville Pickering (1862-1932) was a talented surgeon and clockmaker who listed himself as an Inventor. He lived and worked at 50 Upper Berkeley Street, London, and had an extensive workshop behind his surgery. He made extraordinary regulators throughout his life and his work is held in such high esteem that two examples are kept at the British Horological Institute’s head office, Upton Hall. The tall mahogany case is glazed on 3 sides and has a curved glazed top to allow the extraordinary movement to be viewed from all angles.
The Movement: Fully skeletonised 8 day weight driven movement with 6 spoke wheelwork, dead beat escapement with adjustable jewelled pallets and Harrison’s maintaining power.
The fully pierced plates are mounted on the back plate by two very large turned pillars.
All steel work is blued and the brass work is of a frosted gilt finish.
The weight has a pierced cover and falls via a roller mounted on the side of the case.
The crutch has integral beat adjustment and the steel rod pendulum is suspended from a separate support on the back plate.
The pendulum bob consists of a steel and brass frame supporting a large ribbed glass jar containing mercury.
The backplate has pierced corners and is signed: “made by R N U Pickering London 1914”
