Application filed May 1, 1915. Serial No. 25,145.

To all whom it may concern: 1

Be it known that I, FREDERICK E. BLAKnLY, a citizen of the United States, residing at Douglas, in the county of Cochise and State of Arizona, have invented an Improvement in lVindmills or Motors, of which the following is a specification. Y

My invention relates to improvements in windmills or motors, and more particularly to a type wherein are employed a plurality of fiexible sail members.

The object of the present invention is. the

' provision of an improved machine which will be simple in construction, inexpensive to manufacture, durable and efficlent; to so construct and dispose the sail members that they will catch the lightest breeze ;v and to provide novel means by which the sail area will be automaticallyreduced when the speed of the mill becomes too great for safety due to excessively high winds.

WVith these ends in VlQW' my invention consists in the combination, construction, and arrangement of parts hereinafter fully described and claimed. V

Re'ferring to the drawings, Figure 1 is a view showing the complete mill in elevation.

Fig. 2 is a View taken on the line 22 of Fig. 1. Fig. 3 is an enlarged sectional View of the upper portion of the sail carrying, supporting, Fig. 4 is an enlarged elevation showing the governor arrangement for preventing the machine from running at excessive speed.

Referring more specifically to the drawings in which like reference characters designate like parts in the' several views, the numeral 1 indicates a stand or supporting structure which may be of any suitable design, upon which is mounted the revoluble hollow shaft 2, and the governor supporting brackets 3, 4, and 5. The shaft 2 extends above the stand 1 as shown and has fixedly attached thereto the four lower radial arms 6 and the corresponding upper arms 7. Four steel cables 8 are secured to the collar 9 on the shaft 2 near its upper end and extend outward and downward, being connected to the outer ends of the said upper and lower arms 6 and 7 and the collar 10 also on the shaft 2 near its lower end. The four sail members 11, 12, 13, and 14, are secured to the said cables 8 by means of the loose rings 15 and the sheets or cords 16, the latter being fastened to the rings on the cables next following in direction of Specification of Letters Patent.

known manner around shaft '17. with its ends attached to and controlling means; and,

motion the cables to which their respective v sail members are secured,

Revolubly mounted in the brackets 3, Land 5, on the stand 1, is the shaft 17 of the governor mechanism by means ofwhich excessive speed of the motor is controlled. This shaft 17 has revolublymounted thereon the pulley 18 which is integral with the collar 19, and the revoluble and sliding collar or member 20. Bearing sleeves 18 prevent vertical,

movement of the integral pulley and collar. The arms 21, 22, 23, and 24, and fly-balls 25 are connected to said revoluble collar and sliding collar. or member in the'well shown. Passing loosely arm 21 and collar 19is the flexible line or rope 26. The'foregoi'ng elements (the pul ley 18, collar 19, sliding member 20, arins 21, 22, 23, and 24,-fly-balls 25, and line 26) all rotate together when the motor is in motion, the said pulley 18 .being operatively connected with the pulley 27 on the shaft 2 by the belt 28. Drum 29 is fixedto the shaft 17 as shown having secured thereto one end of the, swivel-line 30. This line 30 passes overthe'sheave 31 and up through the hol- 1 low shaft 2 to theswivel 32 (Fig- 3) to which are made fast the four ring-lines 33 which in turn pass over their respective sheaves 31 in the openings 35 in the shaft 2 1 I and the sheaves 36 upon the arms 7 secured tosaid shaft, thence extending down to the lowermost rings 15 on the cables 8;

' With the foregoing arrangement of sails, lines, shafts, pulleys, sheaves, and governor in mind, the operation of the speed control'-' ling mechanism may be readily comprehended, and is substantially as follows: During a normal rate of rotation of the motor the governor members 18, 19, 20, 21, 22, 23, 241, 25, and 26 revolve about the shaft 17 by reason of the belt 28 and the pulleys 18 and 27. As stated the line 26 is normally loose 8 will serveto raise the sails, thus causing the mill to run slower on accountof, there being less canvas spread to the wind. In other words the result is substantially the same as when reefing sail.

Stays'or guy ropes 37 extend from thetop of the vertical shaft 2 to suitable anchoring means not shown, and power fro'm-the mill may be transmitted by means of belting and the pulley' 38.

A most important feature of my wind mill and to which I desire to call especial.

being on the reverse side of the sail to what it was in the former slantwise position. By this natural automatic and self-tacking movement considerablepower is derived and the minimum of resistance encountered. a In F ig. 2 is shown the position of the sails when the wind is in the direction indicated by the arrows, the mill revolving clockwise. The advantage of the sail arrangement is readily apparent as it will be seen that the greatest possible force and effect of the wind is obtained and utilized, thus assuring a powerful, continuous, and smooth-running machine. V

It will be understood that the weight of the sails'is sufficient to overcome theresisb anceon the swivel-line 30 and to readjustthemselves to a normal fully extended position after a reefing movement induced by excessive speed of the mill due to high winds. 1

I desire it to be understood that I do not confine or limit myself to the specificconstruction herein described; but, on'the other hand I reserve the right to make various 1.
