A fine and potentially historically important George III mahogany striking table regulator, Thomas Mudge and William Dutton, London circa 1770 The nine-pillar twin fusee rack and bell striking movement with plates measuring 9.75 by 6 inches, massive spring barrels, Harrison’s maintaining power to the going train and now with half-deadbeat escapement regulated by half seconds pendulum with cylindrical brass bob, the foliate rococo scroll engraved backplate with arched recess to lower margin and applied with unusual twin scroll-shaped uprights attached via four knopped pillars and connected at the top via a complex bracket with slots cut to take a wide T bar pendulum suspension, the front plate of conforming dimensions inscribed William Dutton & Sons,London over the arched recess to lower margin, the 7.5 inch single sheet silvered brass Roman numeral dial with vacant calendar aperture and signed Tho’s Mudge, Will’m Dutton to centre, with Arabic five minutes to outer track and scroll-pierced blued steel hands, the break-arch case with hinged brass carrying handle and three generous moulded rectangular pads to top over glazed circular dial aperture over concave-topped recessed panel to front door, the sides with arched brass trellis sound frets, the rear with further glazed break-arch door set within the frame of the case, on cavetto moulded skirt base with brass squab feet, 38cm (15ins) high excluding handle. Provenance: The property of a private collector; purchased Sotheby’s, London sale of Good Clocks, Watches, Wristwatches, Barometers and Scientific Instruments, Thursday 5th March 1992 (lot 69). Thomas Mudge was born in Exeter, Devon in 1717 and was apprenticed to George Graham before setting himself up in business at 151 Fleet Street, London in 1748. At around the time of the death of his former Master in 1751, Mudge was joined in partnership by a fellow former apprentice of Graham, William Dutton, who is recorded in Baillie, G.H. Watchmakers & Clockmakers of the World as apprenticed in 1738 and gaining his freedom of the Clockmakers' Company in 1746.The business subsequently traded from 148 Fleet Street and Mudge, whilst in partnership with Dutton, rapidly acquired a reputation as one of England’s outstanding watchmakers. In around 1755, if not earlier, Mudge invented the detached lever escapement, which he first applied to a clock, but when incorporated into a watch became the greatest single improvement ever applied to them.In 1765 Mudge published the book, Thoughts on the Means of Improving Watches, Particularly those for Use at Sea, and the following year, alongside Dutton, was elevated to Liveryman. In around 1771 Thomas Mudge retired to Plymouth in order to spend more time to pursue his development of a marine timekeeper. The first of these went on trial in 1774 where it performed superbly leading to an award of 500 guineas. Mudge went on to complete two others in 1779 in the continuing attempt to satisfy the increasingly difficult requirements set by the Board of Longitude. They were tested by the Astronomer Royal, Nevil Maskelyne, and declared as being unsatisfactory. There followed a controversy in which it was claimed that Maskelyne had not given them a fair trial. A similar controversy had arisen when John Harrison had been denied the full amount of the 1714 prize by the Board of Longitude. Eventually, in 1792, two years before his death, Mudge was awarded £2,500 by a Committee of the House of Commons who decided for Mudge and against the Board of Longitude, then headed by Sir Joseph Banks.In around 1775 Dutton took both his sons (Thomas and Matthew) into the business forming a second partnership of William Dutton and Sons however the name Mudge and Dutton was often still used (mainly for watches) up to around 1790. William Dutton died in 1794 leaving the business to be continued very much in his tradition by his sons Thomas and Matthew. The work of William Dutton can be characterised by its distinctive originality, high quality and attention to detail which one would come to expect from a clockmaker who, alongside Thomas Mudge, succeeded George Graham who in turn had succeeded Thomas Tompion. The movement of the current lot appears to be a unique product of the Mudge and Dutton partnership. The provision of noticeably large diameter spring barrels coupled with a relatively shallow range of gearing to each of the fusees indicates that constant power delivery throughout the duration of the timepiece was off significant importance. This, together with the incorporation of maintaining power to the going train and delicate wheelwork, suggests that the movement was built with accuracy in mind. The highly unusual frame applied to the rear of the backplate indicates that a heavy pendulum (most likely compensated) was probably employed. In addition to this it has been suggested (by the late Charles Allix and Christopher Greenwood from evidence in the form of spare holes, slots etc. within the armature assembly) that, when first made, the current movement may well have employed a form of detached escapement. This possibility is further supported by the relatively low position of the original pallet arbor (in relation to the current escapewheel) which implies that the escapement itself was of highly unusual design and may well been positioned partly above the plates and connected to the pendulum suspended within the top frame of the armature to the rear of the backplate.The possibility of the current lot being originally made with a form of experimental detached escapement warrants further investigation and, if found to be the case, would identify the present timepiece as an example of significant historical importance. Indeed in the in the context of Mudge’s development of his detached escapement the current lot would sit between his famous balance lever table clock of circa 1760-65 (formerly in the possession of Isambard Kingdom Brunel now in the British Museum no. 1958,1006.2118) and his marine chronometers (the first of which was made in 1774). Furthermore, to the best of the cataloguer’s knowledge, this example would have also been the only clock from the Mudge and Dutton workshops to have been made with a detached escapement for regulation by pendulum. It is perhaps appropriate to mention that the late Charles Allix considered this timepiece to be of substantial historic importance and provided his views in a letter written to the vendor many years ago; regrettably this correspondence has been mislaid. When considering other details it is most probable that the current clock remained in the workshops of William Dutton and his successors for a significant time before essentially being ‘re-purposed’ and sold-on. Later work undertaken in the workshop included creating an arched profile to the lower margin of the plates - to allow the swing of the pendulum bob to be visible through apertures cut to the front of the case (including a fretwork overlaid glazed panel beneath the dial). The front upper margin of this arched cut-out was subsequently signed by William Dutton and Sons so this modification post-dates Mudges partnership in the business. In addition to this the original dial was overlaid with a white enamel dial which required the original dial feet to be shortened (and holes drilled to allow clearance the under dial pivot posts) and finally a relatively standard escapement was fitted. Subsequent to the clocks purchase in 1992 the later enamel dial has been removed and is no longer with the clock and the panel beneath the dial has expertly reinstated with fine figured veneer matching the rest of the case. Without a great deal of further work (mainly to the dial) the current lot could become a very attractive useable clock which, through further investigation, also has the potential to be identified (and subsequently restored) as an important example in the development of precision timekeeping.

An important George II/III mahogany domestic regulator, Henry Hindley, York, mid 18th century The substantial eight-day movement with plates measuring 8 by 6.75 inches united by four typical Hindley pattern double baluster pillars, the trains with six-spoke wheel crossings and high pinion count throughout, the going train with deadbeat escapement set low between the plates regulated by seconds pendulum with heavy lenticular bob and long crutch, with bolt-and-shutter maintaining power activated by a line connected to a crossed-out pulley segment positioned behind the dial engaging with a system of sprung levers to apply torque to the centre wheel, the gravity-fed rack striking train sounding the hours on a large bell mounted above the plates via hammer cocked on the backplate against large reverse ‘L’ shaped combined spring and stop, with typical Hindley system of trip-hour repeat incorporating substantial sprung steel lever engaging with the strike lifting detent via wheel on the backplate applied with a pair of pins configured to allow lever to operate in either direction, the calendar work advanced via a pump and system of sprung levers connected to a crank on the calendar wheel set behind the dial, the movement fitted with slide-in dust shutters to sides and top dressing up to the rear of the dial plate,the 12 inch brass break-arch dial with subsidiary seconds dial to the finely matted centre within fine narrow silvered Roman numeral chapter ring with Arabic five minutes to outer track and signed Hen’y Hindley, York to lower margin, with pierced steel hands and rococo scroll cast spandrels to angles beneath arch centred with calendar dial flanked by conforming mounts, the case with giltwood ball finial to the generous ogee-shaped caddy surmount over box frieze applied with crisply moulded swan neck pediment and architectural break-arch mouldings over the hinged glazed dial aperture flanked by substantial Doric columns, the sides with blind break-arch panel doors and conforming full columns to the rear, the trunk with ogee throat moulding over shaped-top caddy moulded door flanked by fluted quarter columns to front angle, on plinth base with cavetto top moulding and bracket feet, 251cm (95ins) high excluding finial; 251.5cm (99ins) high overall. Henry Hindley was born in Great Harwood, near Blackburn, Lancashire 1699, little is known about his early life, however by the mid 1720’s he was making clocks in Wigan where he repaired the church clock in 1726. Hindley moved with his young family (including his son, Joseph born 1728) to the prosperous city of York where, after making clocks for the Mansion House and Guildhall, he gained his Freedom of the city in 1732. Hindley s talents were such that he equipped his workshop with tools of his own design including an important dividing and wheel cutting engine, a screw cutting lathe and a fusee engine. As well as domestic clocks Hindley received commissions for several turret clocks including York Minster and supplied a range of scientific instruments including two important equatorial telescopes for the Duke of Norfolk and William Constable. By the 1760 s Hindley s health had deteriorated to the extent that an ever increasing proportion of the business was handled by his son Joseph. Henry died in 1771 with his son and successor Joseph unfortunately dying just three years later in 1774, before he had had the opportunity to stamp his own mark on the family firm. Hindley s work demonstrates a highly inventive exacting approach with each clock perhaps varying in some way to its predecessor ensuring constant refinement in design and layout. The quality of the finish of his work is generally exceptional being comparable to the very best London makers of the period which is why many collector’s refer to Hindley as the ‘Tompion of the North’. The movement of the current lot is no exception being a particularly fine example of Hindley’s work exhibiting inventive details such as the cranked pumping mechanism for the calendar dial, gravity fed rack striking, concealed clicks to the barrels and combined hammer spring and stop. The bolt-and-shutter maintaining power is beautifully executed and the movement exhibits the rare feature of having brass dust shutters fitted. The winding key present with the clock is suitably finely made and is most probably original.The case is also of the finest quality and as equally distinctive as the movement with the hood in particular featuring fine crisp mouldings and generous architecturally correct Doric columns. Unusually the hood is fixed integral to the trunk hence the movement and dial have to be inserted into the case via the dial aperture, the doors to the sides then allow the pendulum to be hung and the lines for the trip repeat and maintaining power connected. The reason for this arrangement is not obvious but it seems that Hindley sought to make the movement difficult to access/examine on purpose. From this it is perhaps appropriate to speculate that the current lot could have been supplied for a semi-public environment requiring the design to incorporate ‘anti-tampering’ features which would have served to reduce the chances of others copying some Hindley’s innovative features as well as preventing inexperienced individuals making unwelcome adjustments. Indeed if this is the case then it is possible that Hindley himself was initially contracted to tend to the clock. The inside of the trunk door is applied with a paper label inscribed in ink Sep’r 68 and Nov 30th 87 G.W. these probably note/record subsequent servicing of the clock. Indeed the visible positioning of this information also supports the possibility that the current lot was originally supplied for a semi-public environment where such information would need to be visible to ensure that the clock is correctly maintained.

He was succeeded by his widow, Hannah, before the premises was taken over by his brother, Dudley, in 1796. The current lot can be compared to a similar globe illustrated in Lamb, Tom and Collins, Jeremy (ed's.) THE WORLD IN YOUR HANDS (exhibition catalogue) item 5.16 which is described as attributed to George Adams junior based on the same type of globe being used in an armillary sphere by Adams. The origin of the gores can be traced back to those used on Herman Moll's pocket globe of 1710, however it is known that the plates for Moll's gores were acquired by John Senex after the former's death in 1732, before passing to George Adams senior after Senex died in 1755. It is possible that George Adams had the plates re-engraved to incorporate revisions before publishing. With regards to dating - Cook's Track follows the line of his first voyage which took place 1768-71 hence is incorrectly dated 1760, also the presence of New Caledonia would indicate that the globe was produced after Cook's second voyage which ended in 1784.
