A PERPETUAL CLOCK. M. Dardenne's self-winding perpetual clock may now be considered to have had a fair trial. A speci- men clock was fixed at the Gare du Nord Terminus, Brussels, last September, all due precautions being taken to avoid tampering with it by affixing the Go- vernment seal. After six months' trial it was found in perfect time with the Observatory clock, and had not varied in the slightest degree during that time. The clock is wound by a small aIiem»meter windmill which is placed in a £ chimney ?r any other ^lace where ^tol^rablycon^^ r,rer,ed"trr«" of 2SSpl,lng wheel., continually draS over a wheel an endless chain, in one loop of whkh the clock-weight is supported. As the loop hangs between the clock and the winding-machine the weight is continually drawing through the clock the slack chain drawn up by the wind-motor, and thus a constant motion is maintained. A ratchet-wheel prevents the motor from turning the wrong way, and, by a snnplg arrangement, whenever the weight is wound right up to the top the motion is checked by a friction brake automatically applied to the anemometer by the raised weight lifting a lever. When the weight is ihus raised to the top, the clock has a sufficient store of energy to go for twenty-four hours, so that it is not by any means dependent on a regular current of air. As this clock receives such a liberal supply of winding, it does not require so long a train of wheels as aa ordinary clock. The works of the clock are only con- nected with the winding arrangement by means of the loop of chain so that no injurious matters can reach the former from the chimney. M. Dardenne is now supplying these clocks for domestic and office pur- poses.
