WINDMILL.

- SPECIFICATION forming part of Letters Patent No. 372,300, dated November 1, 1887.

Application filed December 16, 1886. Serial No. 221,730. (No model.) A

.To all whom, it may concern:

Be it known that I, AARON F. Gnnnnnox, of Tyrone, in the county of Kent and State of Michigan, have invented anew and Improved Windmill, of which the following is a full, clear, and exact description.

This invention relates to windmills of the upright or vertical typegand it consists, essen tially, of a wheel carried by a vertical shaft, a shield arranged in connection with the wheel, a shield-controlling mechanism, and a'mechanism for imparting a uniform speed to the main shaft of the mill, all as will be hereinaf- 'ter more fully described, and specifically pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the Views.

Figure 1 is a central sectional elevation of my-improved mill, the parts being represented as they appear when, the doors of the shield are thrown open to their full extent. Fig. 2 is a plan view of the'mill, a portion of the roof being broken away and the doors and framing Fig. 3 is a view of the mill, taken just below the roof, the roof-boards, the vane, and the vane-connections being removed. Fig. 4 is a detail sectional plan view of the speedregulating attachment. Fig. 5 is a View of one of the doors or shutters of the shield, representing its connection with the post; and Fig. 6 is an end or face view of the head of the vane, representing the fans carried thereby as they appear when in their extended position, which is the position they assume when the doors of the shield are open. A

In the drawings above referred to, lOrcpresents the inclosing-case of my mill, the wheel portion of which case is arranged to be closed by a number of doors or shutters, 11, which doors are hinged' to vertical posts 12, as will be hereinafter more fully explained. This Wheel-chamber is covered by a roof, 13, and provided-with a floor, 14, said floor being centrally apertured to permit of the passage of the main shaft 15, said shaft being stepped in a post, 16, that is in turn stepped in a socket,

17, that is carried by one of the cross-timbers of the frame, the upper end of the shaft being supported and held by a bearing that is carried by the upper cross-timbers of the frame.

The floats or fans 18 of the wheel are supported by means of radial arms 2, which project outward from the central shaft, 15, each of these arms2 carrying a diagonal bar, 3, the inner edge of which is secured to the next arm in advance, while the outer end of the bar is supported by a cross-brace, 4, that is secured to the radial arm which acts as the main support for the bar 3, the floats being affixed to the bars 3, as is clearly shown in Fig. 3.

The upper hinge of each of the doorsll consists of a metallic rod or bar, 19, one end of which is flattened and apertured in order that it may be bolted or riveted to the door 11. Beyond this flattened portion the rod or bar is bent about itself to form an eye, 21, and from this eye the rod extends outward in the form of an arm, 22, upon one end of which there is an eye, 23.

A screw-stud,-25, is screwed into one of the inner corners of the post 12, and the eye 21 is brought into engagement with this stud,the lower hinge being formed in any manner desired, and of course any form of hinge would answer the purpose. At the top of the doors I prefer this form on account of its cheapness and efficiency for the purpose intended.

To the forward edge of each door there is secured abracingrod, 26, the rear end of which is formed with an eye, 27, that registers with the eye 23. Gonnectinglinks are arranged to extend from the arms 22 of each of the doors to the door in advance, so that there is a com plete systematic connection between all of the doors of the shield, this connection being clearly shown in Fig. 3.

At' opposite points, as a and b, I connect cords c and d, the cords 0 leading forward and over the sheave 31, and then to a point, e, to be united to the cord (1, which extends directly from b to (2. From their point of union the two cords extend outward and over a sheave, 32, and downward to support a weight, 33,

v the tendency of which is to draw the links in the direction of the arrow shown at a in Fi 3, and thereby to open the doors 11; but in order that the said doors may be closed in case the wind should move wit-h too great a velocity,I provide a sh utter-regulating attachment, such as the one illustrated in Figs. 1, 2, and 6. This attachment consists of a horizontal vane-bar, 40, carrying a vane, 41, and having a T-shaped head, 42, which head carries two vertical posts, 43, upon which there are mounted fans 44, each of said fans having an inwardly-extending arm, 45.

The arms 45 are connected with a Swinging lever, 46, by means of connecting-rods 47, and the lever 46 is connected to a looselymounted collar, 48, by means of connecting-rods 49, the rods 49 being pivoted or loosely connected to the collar 48.

The vane and its attachments are supported by a post or standard, 50, that extends upward through the roof 13, being stepped upon the timbers 20, a supporting-bar, 51, extending upward and over the top of the standard and being held thereto by a pivot pin or bolt, 52.

The collar 48 is arranged just above the bifurcated end 53 ofa lever, 54, said lever being mounted upon a standard, 55, and to the long arm of this lever there is connected a cord, i, which passes downward and about a sheave located at f to a point, 9, from which point the rope branches off, one branch leading to the point I), while the other leads to the point a, the section of the rope leading to the point a being, however, carried about a pulley, 56.

It will be noticed that the cord i is arranged in opposition to the cords c and d, and an inspection of Figs. 2 and 3 will show that when the weight moves downward and opens the doors 11 that the fans 44 will be opened so as to extend at right angles from the vane-bar; but should the velocity of the wind increase, the fans 44 will be folded back to the position in which they are shown in Fig. 2, and in so moving will forcethe bifurcatcdend of the lever 54 downward, thereby raising the extending end of said lever and causing said lever to draw the cord 2 upward, which movement of the cord will tend to move the links 30 in a direction contrary to that indicated by the arrow shown at a in Fig. 3, so that the doors 11 will be closed or moved to the position in which they are shown in Fig. 2.

In order that a uniform speed may be imparted to the machinery arranged in connection with the mill, I provide the shaft 15 with a large friction-wheel or pulley, 60, which bears against two smaller friction-wheels, 61, that are supported beneath the flooring 14 by means of a bracket, 62.

Above the wheels 61 there are arranged pulleys 63, which serve as the driving-pulleys for a band or belt, 64, that runs in engagement with a pulley, 65, carried by the counter-shaft 66, said countershaft being provided with a small pulley, 67, that serves as the drivingpulley for a governor, 69, a proper means, not

shown in the drawings,being provided to transmitthe motion of the counter-shaft to the said machinery.

The short arms of the weighted governorlevers ride in an annular groove formed in a collar, 71, that is fixed to the rod or bar 72, said rod or bagbeing secured to the end of the lever 73, that is securely connected to the post 16, the arrangement being such that as the speed of the counter-shaft 66 is unduly increased the governor-levers will move outward and the rod 72 will be drawn backward,which movement will cause the friction-disk 60 to draw away from the friction-wheels 61, thereby decreasing the friction between the parts, and consequently decreasing the number of revolutions of the shaft 66.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patcnt- 1.
