Description

UNITED STATES ATENT OFFICE.
LEVI A. I-IAIGHT, OF KANSAS CITY, MISSOURI.
WINDMILL.
SPECIFICATION forming part of Letters Patent No. 704,030, dated July 8, 1902.
Application filed February 6, 1902. Serial No. 92,946. (No model.)
To ctZZ whom, it may concern/.-
Be it known that I, LEVI A. I-IA1GHT,a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have made a new and useful Improvement in Windmills, of which the following is a specification.
My invention relates most particularly to the governing of a wheel in the construction of which broad wings or feathering-blades may be used, and has for its object the combination of parts so as to provide a more simple and complete windmill in all its parts. I attain this object by the mechanism illustrated in the accompanying drawing, which shows a central section of the wheel. with the blades in position to receive the wind and also shows the entire body of the mill, with its attachments.
In further reference to the drawing similar figures indicate similar parts. i
1 denotes the mast, which should extend through the cap of a tower. The mast supports the framework on which the wheel is mounted and is hollow, so as to afford anf opening for the transmission of power to any work below, and the opening also affords space for the extension of a wire or cord 2,by means of pulling down on which the blades are thrown out of the wind.
3 represents the frame, to which all the parts of the mill are attached.
J ournaled in suitable bearings 4 is a shaft 5, carrying awind-wheel at its outer end. The wheel consists of a hub 6, spokes 7, wings S, and other attachments, which will be here inafter described. The wings are pivotally adjusted on the spokes. Near the inner ends of each-wing I rigidly attach arms 9. These arms should extend at about right angles from the back and flat side of the wings.
10 represents a sleeve, which is made to operate longitudinally on the shaft. The sleeve is provided with arms 11, which extend outward and forward and are connected to the arms 9 by another outward extension through an eye near the end of the arms 9, allowing a free jointed movement in said connection.
In a complete device a sufficient number of wings should be used to cover the entire surface of the wheel when in position to receive the wind. The number will therefore depend 'pull the wings into the wind.

on their width. All the wings should be provided with the rigidly-attached arms 9, and the sleeve should; be provided with an equal number of arms to attach thereto. At the rear end of the frame 3 is secured a tailfvane'12, which operates as a weight to It will be seen that the vane is pivoted at 13. An arm 14 is rigidly attached to the forward end of the vane, and to the top of it is connected a bar 15 by a pin 16, formingafree operative joint. Said bar 15 extends forward and terminates ina fork or yoke made to restin a circumferential groove on the sleeve, so that the outer end of the vane is supported through its connectionwith the wings or to the extent of pulling them into the wind.
At the outer end of two opposite spokes I These lugs ed rod 19 can slip freely therein.
Between the wings and hub are rigidly secured-lugs or arms 20, which support elbowlevers 21. The lugs 20 provide a fulcrum The outer ends of the elbow-levers are connected to the weighted rod 19 by a loose pin or pivot, and
the inner ends are connected in like manner to a rod 22. Said rod extends toward the sleeve, having its other end connected to the seen that th'eioperation is simple. The wings being drawn into the wind by the operation of the vane, the wheel begins to'revolve. As its force is sufficiently increased the weighted arms will be thrown outward by centrifugal force, drawing the sleeve toward the hub and turning the wings proportionately out of the wind. By pulling down on the cord the wheel may be stopped entirely.
I do not claim, broadly, the wings operating onpivots orthe connection ofthe sleeve with the vane, as I am aware that both have heretofore been.used;',but,
What I claim as new, and desire to secure by Letters Patent, is- Y In combination a frame, a shaft mounted thereon, a wheel mounted on said shaft, a
