Description
PATENT OFFICE.
ISAAC MILES, OF BONESTEEL, SOUTH DAKOTA.
WINDMILL.
Specification of Letters Patent.
Patented Oct. 15, 1907.
Application filed December 24. 1906. Serial No. 349,324.
To all whom it may concern: p Be it known that I, ISAAC MILES, a citizen of the United States, residing at Bonest'eel, in the county of Gregory and State of South Dakota, have invented a new and useful Windmill, of which the following is a specification.
This invention relates to windmills, and its object is to provide a structure of this character having its wheel made up of resiliently held blades adapted to flex under pressure of the wind so that after the wind reaches a predetermined velocity these blades will swing upon their connections so as to prevent injury to the mill.
A still further object is to so mount the wheel as to dispense with the use of a vane such as is commonly employed for the purpose of holding the wheel in the wind. 1
Still another object is to mount the drive shaft of the mill in a rotatable head, said head being so constructed as to permit the pump-rod to extend longitudinally therethrough.
With these and other objects in view, the invention consists of certain novel features of construction and combinations of parts which will be hereinafter more fully described and pointed out in the claims.
In the accompanying drawings is shown the preferred form of the invention.
In said drawings:Figure1 is a perspective view of the windmill, a portion of one of the blades of the wheel being removed; Fig. 2 is a vertical section through the windmill, and Fig. 3 is a horizontal section through the upper ends of the corner posts and the parts adjacent thereto. 7
Referring to the figures by characters of reference, 1, 1 are the converging corner posts of the tower, the same being connected and braced in any preferred manner, and the upper ends of these corner posts are secured around a tubular core 2 and bound thereagainst by an outer concentric ring 3, said posts, core and ring being securely fastened together in any preferred manner. Spacing blocks'3 are interposed between the ends of the post and between the core 2 and ring 3. Cross-beams 4 connect the posts at points below their upper ends and support a base 5 on which is fastened a metallic socket 6. This socket'constitutes a bearing for a ferrule 7 formed at the lower end of an inverted frusto-conical head 8, said head having its upper portion cylindrical in form, as shown at 9, and sheathed within a metal jacket 10. which is adapted to bear within the core 2. The head 8 is preferably formed with longitudinal openings 11, and the lower end of this head and the base 5 have registering openings 12 through which the pump-rod 13 is adapted to work. Bearings 14 are secured upon the upper end ofthe head and mounted within them is a crank shaft 15. The crank of this shaft has a link 16 mounted thereon. The lower end of this link has a socket 16 to receive a ball 17 located at the upper end of the pump-rod 13, and this ball is held seated within the socket by means of a cap 18 which is bolted or otherwise fastened to the socket. As a result of this construction it will be seen that the shaft is free to rotate and thereby reciprocate the pump-rod 13. Said shaft 15 is also free to revolve with the head 8 without causing a corresponding revolution of the pumprod.
One end of the shaft 15 is preferably screw-threaded, as shown at 19, and mounted on this threaded portion is a hub 20 which is preferably bound in place upon the shaft by means of nuts 21, or in any other desired manner. The hub has a series of radial sockets 22 in each of which is adjustably mounted one end of an arm 23. These arms radiate from the hub and are held against rotation by means of set-screws 24. Each arm has a blade 25 pivotally connected to it as by means of straps 26, and a torsion spring 27 is secured to the arms 23 and has one end extending at an angle therefrom, as shown at 28, and extended through apertures 29 within the blade. This spring serves to hold the blade normally at a predetermined angle to the plane of rotation of the wheel. When, however, the velocity of the wind passes a predetermined degree, these blades will be swung against the tension of the springs so as to relieve the wheel of undesirable strain.
It is thought that the operation of the windmill will be fully understood from the foregoing description when read in connection with the accompanying drawings. A current of air will keep the wheel at all times at the far side of the tower and as the direction of the wind changes the wheel will be correspondingly shifted. This shifting movement is permitted in view of the fact that the head 8 is free to revolve within the socket 6 and the core 2. The pressure of the wind upon the normally inclined blades 25 will cause the wheel to rotate and when the velocity of the wind reaches an undesirable point the blades will swing out of the wind so that injury to the windmill will not result. The rotation of the wheel causes a corresponding reciprocation of the pump-rod 13. As this rod is swiveled to the link 16 by means of the ball-and-socket connection 16 and 17, it will be understood that the head and wheel will be free to swing upon a vertical center while rotating without twisting the pump-rod or interrupting the reciprocation thereof.
Although a swivel connection has been disclosed between the link 16 and the rod 13 at a point within the head, it is to be understood that if desired this connection may be made at a lower point either within or below the head 8. Any means may be used for stopping the actuation of the pump rod.
The preferred form of the invention has been set forth in the foregoing description but I do not limit myself thereto as I am aware that modifications may be made therein without departing from the spirit or sacrificing the advantages thereof, and I therefore reserve the right to make such changes as fairly fall within the scope of the claims.
What is claimed is:-
In a wind mill the combination with posts, a tubular core interposed between the ends thereof, and a. ring for binding the posts upon the core; of a metallic socket supported between the posts and below the core, a tapered tubular head revolubly mounted at its upper end within the core, :1 ferrule upon the lower end of the head and hearing within the socket, a jacket surroundingjhehead and ISAAC MILES. Witnesses JiiMns M. Brooms, JOHN H. CROOK.
