Show otiii ninaing ciooun. A chain of synchronized self winding elx-ks is being established hero through the efforts of Henry Denver, manager of tho Western Union Telegraph company. The time pieces do not obtain their motive mo-tive power from electrical action, thus being subject to hindrances resulting from entire dependence on electrical currents, but instead gains tho necessary force from tho action of a fine spring, as does an ordinary clock. Two small cells of battery are placed in tho top of the caw, connected with a magnet secured to the lower part of the movement. As the center wheel, driven by t';e unwinding unwind-ing of the spring, advances, a lever is raised that unlocks the armatnro and allows al-lows it to spring back into position ready for winding. When the lever drops the circuit is instantly closed, the spring being be-ing wound by tho pawl fastened to the armature. The action of winding breaks tho circuit cir-cuit when tho winding is completed. Tho contacts are made so short that the action of the battery is very slight, thus enabling it to perform the work of winding wind-ing for over a year without renewal or alteration. Each clock is provided with a simple attachment by means of which its hands may be controlled automatically automat-ically by electricity. To secure absolute uniformity of time throughout the city the clocks will be connected with a time wire just before 12 o'clock each day. During the brief period of connection the standard clock at Washington through the repeating lines takes possession pos-session of the wire, temporarily controlling controll-ing all clocks in its circuit.
