WIND-WHEEL.
SPECIFICATION forming part of Letters Patent No. 224,817, dated.
February 24, 1880.
Application filed December 1, 1879.-
than ordinary.
The novelty consists in securing to the hub two sets of parallel, or nearly parallel, arms,- each pa1r being connected by a brace at its outer end and supporting curved sheet-metal Wingsor buckets attached to the arms, all as will be herewith set forth and specifically claimed.
In the accompanying drawings, Figure 1 is a perspective View of our improved wind-wheel. Fig. 2 is a rear elevation of the same.
Upon the spindle A is fitted a hollow conical hub, B, with its apex outward. The rear edge of this hub has, in the present instance, six radial arms, 0, to which are fastened, in any suitable manner, the radial supporting arms D. At the front or apex of the hub is a flanged cap, E, to which are fastened, in any.
proper way, the radial arms F, which correspond in number with and are parallel to the arms D. Thelengths of these arms D and F are made to suit the desiied diameter of the wheel. In the present instance we have represented each of the pairs of arms D and F as of one piece, united, at their outer ends by the right-angular integral brace-piece Gr, though, if desired these braces may be separate pieces, attached to thearms in any suitable manner.
This construction so far furnishes a framework light, though strong, whereon to secure the blades or fans H of the wheel, These blades are made of sheet metal, and are curved segments, as shown. The ends of each one are attached to and extend from one of the arms, F, to thenext adjacent arm, D, as represented. To stiffen them we apply strips of metal, I, which are riveted to the rear sides, as seen in Fig. 2.
This construction produces a wind-Wheel which isnot only very powerful but is light and very strong; and,
Having thus fully described our invention,
3. In awind-wheel, the sheet-metal sails 0t" theform shown, havingstiftening ribs or braces I on their rear surfaces, as set forth.
I Witness our hands this 24th day of October, A. D. 1879.
