A FINE ENGLISH NICKEL-PLATED BRASS AND MAHOGANY ELECTRIC TABLE CLOCKEVERY READY FOR RETAIL BY THE LONDON STEREOSCOPICPANY, LONDON, CIRCA 1905The movement with transverse saw-tooth Hipp toggle type escape wheel regulated by the front-and-back swinging pendulum via a pivoted detent engaging with a small slot to the apex of each tooth of the escape wheel to pull it during the front-to-back cycle of the swing, during this part of the cycle the detent also momentarily engages an electrical connection to facilitate impulse to the steel bar pendulum bob via an electromagnetic field generated by the coils positioned beneath, the rotation of the escape wheel transferred via a worm gear to motionwork positioned behind a brass plate to the rear of the dial stamped with serial number 1313, the 4.75inch circular white enamel dial inscribed LONDON STEREOSCOPICPANY, 106 & 108 REGENT ST., LONDON to centre within vertically aligned Arabic numeral chapter ring and minute markers outer track, with blued steel spade hands and set within cavetto moulded nickel-plated surround surmounted by an arched panel to support the knife-edge pendulum spension flanked by a pair of urn finials, supported on four column uprights incorporating balter-turned inserts to shafts and the outer pair with right-angled fitments to support the mechanism from the sides, the mahogany box base fitted with bubble level and pendulum bob check pieces to top and enclosing coil assembly, batteries and necessary electrical wiring within the box incorporating a fold-down flap to front, on stepped ogee moulded shallow skirts and with nickel-finish framed bevel-glazed rectangular cover incorporating mirror glass panel to rear.44cm (17.25ins) high, 29cm (11.5ins) wide, 19.5cm (7.75ins) deep.The design of the current lot was conceived by Herbert Scott (1885-1943) and was patented by him (No. 10,271) in 1902. His intention was to utilise the principle of the Hipp toggle for impulsing the pendulum electromagnetically via coils positioned beneath the bob. After the patent was granted Herbert Scott entrted the Every Ready Specialitiespany to manufacture the timepieces; they however did not prove to be a greatmercial success and relatively few were made in what was a rapidly evolving market place.The London Stereoscopicpany can trace its roots back to 1854 with the opening of the 'London Streoscopepany' at 313 Oxford Street. They operated as suppliers of stereoscopic images and equipment but as the century progressed they branched out to also sell related domestic apparat such as phonographs and, in the case of the current lot, electric timepieces. The premises at 106 and 108 Regent Street were opened around 1865 and biness continued there until thepany was dissolved in 1922.The current lot has survived in very fine original condition. The provision of a full box base in mahogany is a rare feature which sets it aside from almost all of the other known surviving examples w
