JAMES J. MGDILL, OF DES MOINES, IOWA.
IMPRQVEMENT iN lND= WHEEL$-' Specification forming part of Letters Patent No.132,?68, dated November 5, 1872.
To all whom it may concern:
Be it known that I, JAMES J. MGDILL, of Des Moines, inthe county of Folk and State of Iowa, have invented certain Improvements in Wind -Wheels, of which the following is a specification:
The object of my invention is to provide an adjustable wind-wheel that will yield to the pressure of strong and heavy gales and allow the force of the storm to pass without meeting the usual resistance presen ted by the fans and wings of the wheel. It consists, first, in pivoting the wings to the arms of the wheel in such a manner that they will be adjusted by the pressure of the wind and again made to resume their naturalpositions by means of weights attached; second, in combining the wings with bars in such a manner that the wings can be turned up and made inoperative at pleasure, all as hereinafter fully set forth.
Figure 1 of my drawing is a perspective view of one of the wings of my wheel, and illustrates the manner of forming, constructing, and connecting the Various parts of which it is composed. a
A A is the arm; B B, the frame of the wing O, a weight, attached by means of a rod. to (I, represent a series of fans journaled in the top and bottom pieces of the frame B B. The journals are at or near the front edge of the fan. I) b are rods extending nearly at a right angle from the center of the front edges of fans, and
serve to prevent the fans from turning beyond a right angle with thefraine in which they are operated. c c are common bearin gs, upon which the frame B B is suspended and pivoted. f is a rod attached to the frame and extending above the arm. Pressure applied to the top of this rod will turn the frame or wing from a vertical to a horizontal position. A hard blast of wind against the back will close the fans, and also press forward and upward the wing and the weight 0, as indicated by the dotted lines. A self-adjustin g wing for wind-wheels is thus provided which will readily yield to a storm and prevent the destruction of the windmill. When the storm is passed the force of gravity in the weight 0 will cause the wing to resume its natural vertical position on the horizontal arm.
The frame B B may be suspended above or below the arm.
Fig. 2 is a miniature perspective view, illustrating themanner of mounting and operating my wind-wheel. They may vary in size and number of wings, as desired.
1 2 3 4 represent the posts of a common frame. The arms A are fastened to theshafts H H in a common way. A common crank-connection or bevel-gearing is used to communicate power. D D represent two or more bars framed together and pivoted to the top of the shaft H H. F is a lever pivoted to the under side of one of the arms A. d is a rod connecting the lever F with the joined bars D. G is a pole attached to the posts insuch a manner that it can be raised and lowered to operate the pivotedlever F. I
When the pole G is raised to reach the lever F it will press it to a side, and, by means of the connecting-rod cl, move the joined bars D D. These bars D will press upon the rods f and cause the wings to become inoperative.
the purposes specified.
JAMES J. MGDILL.
