WIND-'WHEEL.

SPECIFICATION forming part of Letters Patent No. 450,411, dated April 14, 1891.

Application filed October 9, 1890.

To all whom it may concern Be it known that I, MAX IRRGANG, a citizen of Germany, residing at Bowmanville, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Wind-Wheels; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to wind-wheels; and it consists of improvements in horizontal wheels of this class, as hereinafter fully described.

In the accompanying drawings, Figure 1 shows a top view of my improved wheel. Figs. 2, 3, and 4 are details showing the move ment of the blades. Fig. 5 is an elevation of the wheel, showing two opposite arms, intervening arms being removed. Fig. 6 is a detail of the automatic device for relieving the blades from excessive pressure in the event of storms. Fig. 7 shows the manner of pivoting the blades. Figs. 8 and 9 aredetails of the device for controlling the blades.

The wheel, consisting of any number of ra diating arms A A A, is keyed upon a vertical shaft a, which is journaled in the upright frame a. The arms A carry vertical rectangular sail-frames a a between the sides of which are pivoted the slats or blades 13 B bymeans of the pins 19, secured near one side of the blade, and the socket-plates b, attached to the frame. The frames of are set out from the arms A by means of the blocks X a sufficient distance to permit the blades B to open toward said arms. The distance between the adjacent blades is slightly greater than their width. Abar Ois located between the frame a and the arm A and is carried by the blocks X by means of links 0 which are pivoted both to the blocks and bar, so as to admit of a longitudinal and a lateral movement of the bar. An in-thrust of the bar 0 throws it against the frame a and prevents the blades B from turning in toward the arm A. An out-thrust of the bar 0 throws it against the arm A, permitting the blades to turn back freely. Stop-rods c extend laterally from the arm A through the frame a ad- $erial No. 367,518. (No model.)

jacent to and at the outer side of the pivoted point of the blades B, whereby said blades are limited in their movement to a half-revolution.

\Vhen the bar 0 is thrown against the frame a the action of the wind causes the blades to close and open at each revolution of the wheel. The wheel moves from left to right. As each arm comes parallel with the direction of the wind the blades are closed, and as the wheel continues to turn the sail receives the full force of the wind. When the sail has again passed the line of direction of the wind, the blades open and the air passes freely between them. The direction of the wind is immaterial to the action of the wheel.

It being desirable to have the wheel under control, this object is attained in the following manner: The rod 0 is pivotally connected with the vertical arm of the three-arm bellcrank c, pivoted upon'the arm A upon the opposite side of the wheel. One of the horizontal arms of the bell-crank is prolonged and carries a weight 0 which holds the rod 0 against the frame a A sliding sleeve D is mounted upon the shaft a immediately below the hub E, which carries the arm A. This sleeve is connected by the rod cl with the hand-lever F, operating in connection with the ordinary ratchet-segment f, whereby the sleeve D may be raised or lowered at pleasure. A collar G,having radiating arms g g, is carried by and revolves freelyv upon the sleeve D, which is suitably grooved to retain it. A rod or link r, pivoted to the in ner arm of the bell-crank of, passes down: wardly through an aperture in the arm g and carries a nut g on its lower end, so that when the arm of the bell-crank to which it is attached is depressed it slides freely in the aperture; but the nut g prevents the upward movement of the bell-crank arm. When the hand-lever Fis released from its engagement with the ratchet f, the weight raises the sleeve G and throws the bar 0 against the frame preventing the blades B from turning backward, so that the wheel is brought into action.

In the event of a wind storm the pressure upon the blades and the arm 0 is sufficient to raise the weight 0 the blades turning back, so as to partially relieve the pressure. By

ICO

adjusting the weight upon the arm of the bell-crank the power, and consequently the speed of the wheel, can in a great measure be regulated. By means of the hand-lever F the sleeve D may be drawn down, thus raising the weight 0 and throwing. the bar 0 away from the frame (b when the blades B are allowed to turn back freely and the wheel is out of action.

I have described the construction of a single sail-arm. It will be seen that they are all alike, each being provided with a pressure-bar, weighted bell'crank, and attachment to the collar G.

To secure strength andfreedom of action, it is desirable to prolong the shaft a upwardly to support truss-rods II. A con nectingrod K should unite the outer ends of the adjacent sail-arms, and spurs 6 should project downwardly from the hub E to engage the sleeveD.

Having described my improved wind-wheel, whatI'claim as my invention is 1. In a wind-wheel moving in-a horizontal plane, the combination, with the shaft carrying radiating arms, of vertical sail-frames mounted upon sail-arms, blades pivoted in the upper and lower sides-of said frames, the stop-bar O for limiting the rotation of the blades, and a stop-rod extending laterally from the sail-arm adjacent to each blade, substantially as described.

2. In ahorizontal Wind-wheel having vertical sail-frames and swinging blades, the combination, substantially as described, of a stop-- bar 0 for limiting the movement of the blades, swinging links for securing the bar to the sail-arm, a bell-crank having a vertical arm connected with the stop-bar, ahorizontal arm carrying an adjustable weight, and a secondhorizontal arm opposite to the weighted arm, and means for depressing the second horizontal arm.

3. In a horizontal wind-wheel, the combina* tion of vertical sail-frames having swinging blades, stop-rods extending laterally from the sail-arms and adjacent to each blade, a stopbar extending perpendicularly to the lateral stop-rods, swinging links for securing the stop-bar to the frame and imparting to it a lateral motion, a bell-crank for operating the stop-bar and having a vertical arm attached to the said bar, a horizontal arm extendingin an opposite direction to said bar and carrying a sliding weight, and a second horizontal arm opposite to the weighted arm, a vertical sliding. sleeve carried by the main shaft, a link depending from the second'horizontal arm of the bell-crank and sliding in an aperture in the sleeve, a head or cross-bar upon the lower end of the link, a hand-lever'for drawing down the sleeve, and a link or chain connecting the lever and sleeve, substan tially as described, and forthe purposes'set forth.

In testimony whereof I affiX my signature in presence of two witnesses.

MAX IRRGANG.
