DESCRIPTION:Matthaus Hipp, Neuchatel, a rare electromagnetic timepiece with skeletonized dial, the cast iron openwork frame mounted to a molded wooden base on toupie feet, the frame both concealing the wiring, and supporting the electromagnet, movement and roman numeral, white enamel dial, black painted Breguet style hands, and central indicator showing dead seconds, very heavy faux gridiron pendulum with damascened bob and jeweled toggle, spotted, oblong brass plate below the movement carrying the contact and engraved "M. Hipp Neuchatel Suisse", with glass dome
CONDITION:base with minor joint separation at back, front section of base reglued, minor dings and scratches, feet dirty, cast frame very good, movement and other brass components appear to retain their original lacquer, dial with faint hairlines at 2 00, 9 00, hands painted, pendulum bob with minor spotting, the two narrow steel pendulum rods with minor oxide, dome good. Appears to be complete, but operating condition unknown. Matthaus Hipp (1813 - 1893) was born in Blaubeuren, and at age 16 he was apprenticed to clockmaker Johan Eichelhofer. He was a pioneer in the field of electrical timekeeping, and was regarded by Frank Hope Jones as among the most important early contributors to this discipline. In addition to his horological achievements, Hipp also made significant contributions to telegraphy, developed a visual traffic signal, an electric loom, and an electric clavier.

DESCRIPTION:Herbert Scott/ Ever Ready Specialties Co., a rare electromagnetic mantel timepiece, the arabic numeral white enamel dial with blued steel hands and nickelled bezel, supported by four slender columns with flaring bases, decorative turnings, and two turned finials, brass movement with two wheel train, the pendulum with unusual knife edge suspension and cylindrical brass bob, swinging front to back behind the dial, and receiving periodic impulse from an electromagnet, all on a molded, rectangular mahogany base with adjustable brass feet, level, terminals at the back, and protected by a rectangular dome with bevelled glasses, mirrored back, and mahogany top matching the base, serial #1305
CONDITION:very good overall, nickel plating very good, dial with a few minor scratches, hour hand with minor bends, bezel with minor dent at left where it joins the column, bob and indicator good, trailer a poorly made replacement, base with minor dings and scratches, wooden components with fading, dome very good, mirror with minor crack at upper right, not running. Herbert Scott (1865 - 1943) was born in Bradford, Yorkshire, England. In 1902 he secured a patent for the mechanism used in this clock. A variation on Hipp's toggle, there are V notches at the tips of all escape wheel teeth, and a pivoted, L shaped trailer at the top of the pendulum rod. Following impulse, the trailer gathers the escape wheel teeth one at a time, thereby steadily advancing the hands. The pendulum amplitude eventually falls to a point where the trailer will no longer gather another tooth, and comes to rest in the V notch at a tooth tip. A projection on the trailer now is in line with the contact, and closes the circuit, thereby energizing the magnet, and providing impulse to the pendulum.
