Improved Double Power Wheel.

    In this improvement we have a device for combining wheels driven by the force of running water, and also by the weight of the fluid, both acting in the same direction, and the latter using the water which has already given power to the former.
    Fig. 1 shows the external appearance of the case of the wheel, and Fig. 2 the two motors with their gearing. The stream is received at A., Fig. 1, and, by the spiral form of the case, is forced to receive a rotary motion as in the common turbine. This water acts directly on the buckets, B., Fig. 2, which radiate from the center. They are connected to a hollow shaft, which carries the large bevel gear, C., gearing into the pinion, D., on the horizontal shaft.
    Passing through the inside of this main shaft is the shaft E., to which the scroll wheel, F., is secured at the bottom, and a heel gear, smaller than C., at the top. This gear meshes with the pinion, G., on the horizontal shaft. After the water, by its rotary force, has done its work on B., it falls and operates F., giving it twice the speed of B. By this combination it is claimed that this device has twice the power of an ordinary wheel with the same weight and force of water. It has been tested by a practical millwright with even greater reported results.
    It was patented January 30, 1866 by L. D. Wynkoop, of Owasso, Mich., who will readily give any further particulars desired.
