Wind Winds A Clock

The Garro d.4 Nord, Brussels, has been fitted with a mechanical wonder in the : shape of a clock, which, although constantly exposed to all kinds of weather, never gets out of repair, nor does it need to be wound by the hanü of man. It is a perpetual timekeeper of the most unique and original design, the running weight being kept in constant motion either through i;ho influence of gravitation, aa when on the descending trip, or by the wind's action on a fan attachment whicb causes the weight to rise to a level with the top of the framework. The winding attachment is not a windmill of the regulation type, but is a fan placed in a common chimney, the paddies being acted upon by the natural "up cast" or "draft." As soon as this fan has raised .the "running weight" to its extreme height, the cord to which the weight is attached acts on a wheel which throws a braka into gear, and tho inore rounds of cord that are added, so much more stronglv does the brake act to prevent the weight from rising any higher, the checking tendency being transmitted to the fan wheel with every revoluti on. A simple pawl arrangement prevenía the down draft from exerting any contrary influence on the fan wheel. There is not, as one might supposo on first thought, any necessity of having a firo in the stove or fireplace of the chimney to which this odd clock ió attached. The natural tendency of air is to ascend through such vents, the draft thus created being always sufficient for weight winding piirposes. The clock might hi placed at tho top of a hollow tree with a bottom opening, or any other cylinder from fifteen to twenty-five feet in height. With its present attachments this clock runs but twenty-four hours aftcr the winding fan stops, but by the aduition of another wheel or two, might be made to run a month or two even though the up draft were not sufficiently strong' to turn the winding wheel in the meantime.
