WINDMILL.

SPECIFICATION forming part of Letters Patent No. 250,661, dated December 13, 1881.

Application filed September 14,1881. (No model.)

To all whom it may concern:

Be it known thatl, CLARENCE J. HAMILTON, of Plymouth, in the county of Wayne and State of Michigan, have invented an Improvement in Windmills, of which the following is a specification.

Thenature of this invention relates to certain new and useful improvements in the construction of windmills; and the invention consists, first, in the peculiar construction and arrangement of parts, whereby the sails of the wind-wheel are automatically presented to the action of the wind; second, in the peculiar construction and arrangement of parts for throwing the sails out of the wind; and, third, in the peculiar construction, arrangement, and various combinations of the parts, all as more fully hereinafter set forth.

Figure 1 is a perspective view. Fig.2 is an elevation of the automatic governor and connections therewith. Fig. 3 is a detailed perspective of governor-connections for throwing in and out of wind.

In the accompanying drawings, which form 2 5 a part of this specification, A represents a'suitable turn-table, which is mounted upon a hollow stand-rod, B, which, in turn, is supported by any suitable frame-work. In this turn-table A is journaled the shaft O, in proper bearings;

0 and to the outer end of such shaft is rigidly secured the hub D of the wind-wheel E. To

this wheel E are rigidly secured the inner ends of the arms F, which radiate in lines tangential from the periphery of the hub D, and these 3 5 arms are further secured at theproper distances apart by means of the band G, to which they are rigidly attached. To the outer portions of these arms are pivotally secured the sails H h h, which are of the class usually denominated 4o double-winged sails, the smaller ones, h, of

which are connected together pivotally by the rods a.

Properly journaled upon the shaft (Land between the hub D and the end of the turn-table,

5 is an elongated plate, I, to each end of which is rigidly secured a bar, J, the outer end of each of which is connected by means of alink or rod, 1), to the smaller portion, h, of one of the sails, H, as is clearly shown in Fig.2. Each of these bars J has pivoted to or near its outer 5o endalever, K, the outer or longer arm of which is provided with an adjustable weight, L, while the shorter arm is connected by means of a link, 0, to one of the arms F, the parts being arranged and constructed as is clearly shown in the drawings. The rear end of the shaft 0 is connected by any proper means to the pumprod in such a manner as to impart a reciprocating motion to the same.

Upon opposite sides of the plate I, andnear the ends thereof, are pivotally secured the bellcrank levers M, the shorter arms of which impinge against pins 0, Fig. 3, which are secured to the wind-wheel E; or such arms may impinge against one of the spokes of the windwheel where the construction of the wheel will admit of it. The longer arms of these bellcrank levers M impinge against the face of the annular ring N, which is capable of having a horizontal movement upon the turn-table, and by which it is guided, said ring being secured to a frame, 0. It is guided in its movements by the turn-table, which is connected by means of bars P to the yoke R, which, in turn, is rigidly secured to the lever S, which is fulcrumed between projectionsT from the turn-table. A coil-spring, h, is secured at one end to the short arm of this lever S, while its opposite end is secured at any suitable pointupon the table, and is for the purpose of retaining the annular ringNin its retracted position, as hereinafter described, while the lever S has secured to its longer arm a rod or cable, U, which extends down to within easy reach from the ground, andby means of which the annular ring may be projected for the purposes herein after explained.

'In practice, when the wind is blowing at a moderate force it strikes the sails H upon the side,usuall y near the rear face of the wheel, and causes the wheel to revolve, and imparts a reciprocating motion to the pumprod. As the wind increases in force and the wheel has a tendency to revolve with a greater velocity, the weights L will, by centrifugal force,be compolled to assume a linewith the bars J, and therefore must necessarily, by the connectingrods hereinbefore named, draw the sails and turn them so that their edges will be presented to the wind, the action of these weights and their connections upon the sails causing them to present a lesser area of their surface to the action of the wind as the latter increases in force. As the wind decreases again the parts assume their normal condition, and are assisted in this action by the coil-springs 71. hen it is desired to throw the sails entirely out of the wind and retain them in that position, the annular ring N is projected by pulling down upon the cord U, causing the said ring to press against the longer arms of the levers M,which,

their shorterarms finding resistance upon the pins'e, causes the plate I and its connections to move radially, and thus draw the sails so that their edges will be presented to the action of the wind.

What I claim as my invention is 1. In a windmill, the sails H, consisting of wide wings h and narrow wings h, secured to opposite sides of the arms F, in combination with the weights L and connections, substantially as described, between the weights and sails, whereby the centrifugal action of the weights when the wheel is turning will cause them to move toward the circumference of the wheel to regulate the positions of the'sails, as set forth.

2. In a windmill, and in combination with the plate I and its connections, substantially as described, the horizontal moving ring N and frame 0, secured to the yoke R by means of the bars 1?, said yoke being secured to a lever,

S, as described, and by means of which the said ring and its frame are projected or retracted for the purpose of operating the lever M, fulcrumed on the plate I, substantially as and for the purposes set forth.

3. In a windmill, the pivoted sails H, provided with wings h h, of unequal area, and connected by rods to, in combination with the plate I, rods J, weights L, weight-levers K, rods 1) 0, and the springs i, substantially as and for the purpose specified.

4. In a windmill, the pivoted sails H h h, plate I, rods J, weights L, weight-levers K, rods 1) c, and springs i, in combination with the lever M, the horizontally-sliding ring N, frame 0, rods P, yoke It, lever S, spring h, and cord U, substantially as described, and for the purpose specified.
