Abstract
202,826. Mercer, T., and Mercer, F., (trading as Mercer, T. & F.). Aug. 3, 1922. Electric clocks; dials. - In a control chronometer of the kind which sends electric impulses at predetermined intervals to clocks or to the controls of recording-instruments, the electric contacts are so arranged that they are readily accessible without dismounting the chronometer. The terminals g, h, Fig. 1 which are connected to the electric contacts e, f by wires i, j, are secured to a block l of insulating-material attached to the chronometer casing. An opening r in the dial renders the contacts e, f visible and accessible. The fixed contact e is in the form of a pivoted disc provided with a notched head that permits the disc to be turned so as to bring a fresh portion opposite the movable contact f. The teeth of a toothed wheel t secured to the fourth pinion may operate the contact f once a second by engagement with a pin s, or the contact f may be allowed to operate every half-minute by notches t', Fig. 6, cut in the wheel t and adapted to be engaged by a roller u. The stem of the contract f may be adjustably secured on its support v.
