` IMPRVEMENT IN WINDMILLS.
' Specication forming part of Letters Patent No. 126,955, dated May 21, 1872; 'antedated May 7, 1872.
' ters of reference marked thereon.
Figure l represents a side elevation of my improved windmill, with a portion of the outer hoop ofthe wheel broken away to exhibit the inner hoop. Fig. 2 represents a face View of the Wheel with the adjusting-ring and cranks. Fig. 3 represents a portion of the wheel without the adjusting-ring and cranks.
My invention relates to the combination and arrangement of the pivoted vanes of the windwheel with a self -`regulating. mechanism, as herein fully described.
The wheel-hub A is provided with six arms, c, to which two metal hoops, ff, are fastened. Between these hoops the wheel-vanes b, of the form shown in the drawing, are pivoted, so as' to turn upon their longitudinal axes, when adjusted, by the action of the regulating-hap B. The wheel-shaft U is journaled in the two boxes g g, and extends out over the tubular seat D, and may be provided with a crank, to which the valve-rod of a pump may be connected. The central frame-piece E has a circular hole through it, into whichthe upper end ofthe tubular seat D is fastened, and its lower end D extends down into a hollow trunk, denoted in dotted lines in Fig. l, in which it will revolve as the direction of the windacting up' on weather-vane F will require. Two braces, d, are employed to strengthen the uprights c', in which the regulating-nap B is hinged. The hinged rod h connects iiap B with the frame i, which is hinged at its lower end and is connected by two at liuks,j, to the yoke k, which ts loosely in the neck of the collar l, which collar revolves with the shaft C. The circular flange m (for which a cross-bar could be arms a, where theirends are bent at right angles and connect, respectively, with the double crank-levers o at the ends of crank-arms p. The crank-levers are each hinged or jour naled in lugs on the hubs` and in holes through the central hoop f of the wheel A', in which hoop the inner ends of the vanes b are pivoted. This hoop is of nearly equal diameter and concentric with the adjusting ring or wheel e. The respective arms r of the cranks o are hinged to the small cranks s, which are jour naled in the adjusting-ring e. The inner ends of the varies b have straps of metal riveted to them, which straps are bent at their projecting ends t, where they extend outside of the ring o and form ears for the hinge, to which the short bent link uis pivoted. This link has one end pivoted to the adjusting ring or wheel e, and thelatter is actuated through cranks s and o and the rods 1' and the other devices which connect the adjusting-wheel e with the iiap B. The wheel or ring e is provided with four spokes and a hub, the latter being free to rotate upon the projecting end of the shaft C, to allow the necessary adjustments of the vanes b. To the upper projecting end of the pivoted flap-beam H a rod, I, is hinged and extends down for the purpose of adjusting the vanes b by a person upon the ground.
From the foregoing description it will be understood that the positions of the vanes b, and consequently the degree of speed of the wheel A', will be regulated by the iiap B, which will change its positions with the varying power of the wind acting upon it. The connections between the sliding collar l and the vanes b and between the liap B and the collar lare so arranged as to effect the abovedescribed movements of the Yanes b by tHe action of the wind upon ap B and by its own gravity.
Having fully described the construction and operation of my improved windmill, what I claim herein, and desire to secure by Letters Patent, is-
ap B and the devices by which it actuantes In testimony hereof I have hereunto set my the sliding collar l, substantially as and for hand this 7th dey of September, A. D. 1871.
