The central verticalspindle tends to revolve continuously by virtue of its connection with the driving gear of the clock, but whenthe arm which it carries swings halfwayfn^ H ^KUl^^^^^ round, the little spherical weight, sus- ll ^ fi 11 pended from it by a thread, is thrown out- ward by centrifugal action ; and when thethread touches one of the fixed verticalwires at the side of the clock, the momen-tum of the spherical weight causes it towind the thread around the vertical wireand stop the arm and spindle. As soonas the thread is wound upon the spindle,the spherical weight unwinds it by its owngravity, and in so doing receives enoughmomentum to rewind the thread and stillprevent the spindle from revolving. Then. 270 HOROLOGICAL, TIME DEVICES, ETC. the thread winds and unwinds once more, when the arm is released, andmakes a half revolution, when the thread is wound on the other verticalwire, and the operation just described is repeated. 705. SELF-WINDING, SYNCHRONIZING CLOCK. O, P,electric motors operated by a local battery. Clocks used in the syn-chronizing circuit are providedwith the synchronizing magnet, D,and with mechanism associatedwith its armature lever and theclock movement. On the minute-hand arbor is mounted a disk, Q,provided with two projections, 4,5, and the second-hand arbor isprovided with a heart-shaped armature, E, is rigidly at-tached to the le
