AN ENGLISH NICKEL-PLATED BRASS AND MAHOGANY ELECTRIC TABLE TIMEPIECEEVERY READY, 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, the 4.75inch circular white enamel dial with vertically aligned Arabic hour numerals to 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 suspension flanked by a pair of urn finials, supported on four column uprights incorporating baluster-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 skirt 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 entrusted the Every Ready Specialities Company to manufacture the timepieces; they however did not prove to be a great commercial success and relatively few were made in what was a rapidly evolving market place.The provision of a full box base in mahogany to the current lot is a rare feature which sets it aside from most of the other known surviving examples which were generally supplied simple platform bases.
