JOHN M. BARNES, OF WAOOUSTA, ASSIGNOR OF ONE-HALF OF HIS RIGHT TO WESLEY S. PALMER, OF LANSING, MICHIGAN..

WINDMILL.

SPECIFICATION forming part of Letters Patent No. 223,465, dated January 13, 1880.

` Application filed ovember 1, 1879.

To all whom it may concern:

Be it known that I, JOHN M. BARNES, of Wacousta, in the county of Clinton and State of Michigan, have invented certain new and useful Improvements in Windmills; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specification, and in which- Figures l and 2 are perspective views of a Windmill with my improvements attached. Fig. 3 isa vertical section of same.

My invention relates to that class of wind mills wherein the face-pressure automatically controls the pitch of the blades; and it con sists in sundry details of construction, as herein after more specifically describedan d claimed. To enable others skilled in the art to make and use my invention, I' will proceed to describe the exact manner in which I have carried it out.

In the drawings, Arepresents the base, and B B the vertical supports, connected together by metallic ring brackets or plates b b', through and upon which the turn-table O is mounted, it being secured from vertical movement by means of the flanges and the set-screw c2.

D represents the crank-shaft, near one end of which is mounted the wind-wheel E, said shaft beingjournaled in suitable bearings cc', formed on the sides of the turn table, the bearing c being extended outward to form a bearing, c3, upon which is secured the vane F.

d represents a rod forming a pivoted oonnection between the crank-shaft D and the vertical shaft G, which passes down through the turn-table. This shaft G is made in two sections, g g', connected together by a swiveljoint or ball-coupling, g2, the lower section be 40 ing made square and passing through a square hole in the cross-plate b2, thus permitting a -free vertical movement of the shaft G and a revolving movement of the upper section, g, as the turntable is revolved, turning the wind- Wheel always in the proper direction to the wind.

H represents a circular disk provided with a series of grooves, h, on its outer face, in which the inner ends of the radial arms 7i are secured, and to said arms are rigidly secured the stationary inner and outer annular rims,

h2 h3, in which the wind or fan bladesz are pivoted. The upper and inner ends of said fan-blades are also pivoted to the outer movable annular rim, 1l. Two of the wind or fan- 55 blades, directly opposite each other, are provided with crank-arms .7 j on their inner ends, which are connected, by rods la lo, with movable levers and collar k', loosely mounted on the shaft D. Y 6o L represents an elbow forked -arm lever, pivoted in the upper end of the curved uprights l Z, the forked arm of said lever engaging with an annular slot in an independent sliding hub,g/, on shaft D, the long arm or free end of the lever being provided with an adjustable weight, Z', secured in any desired po sition upon said arm by a set-screw, l2.

M represents a cord having one endse cured to a lug, m, on the forked,` arm of lever 7o L, and passing over a pulley, m', and thence down through the turn-table and through the lower section, g', of the shaft G, said cord being for the purpose of throwing the mill out of gear. l

N represents a series of short brace-rods rigidly secured at their outer ends to near the center of the radial arms h', and their inner ends secured to an adjustable collar, n,mount ed on the end of the shaft D.

By my improved construction of mill different velocities of wind will not affect the motion ofthe wind-wheel, and the wind, striking the fans at an angle, straightens them so as to cut the wind, and this operates the weighted lever through the medium of the two wind or fan blades connected therewith, keeping a steady motion and working said lever up and down, thus cont-rolling the motion.

l am aware that windmills have heretofore 9o been made wherein the pitch of the blades is automatically controlled by means of the entire wheel movingon the shaft and provided with connecting-levers to raise a weight.

I am also aware that wind-wheels have heretofore been made wherein an independent sliding hub has been given a torsional movement around the shaft by means of the face-press ure and said independent hub raisingaweight as the blades open for relief from the faceroo pressure, and hence I do not broadly claim either the controlling the pitch by the facepressure or controlling the pitch by an inde-y lever-arms K', sliding longitudinally on the pendent hub moving on the shaft; but, shaft, in combination with the crank-armsjj Having thus described my invention, what pivoted blades 'i Q), movable rim i', and Xed I claim as new, and desire to secure by Letrims h2 and h3, all constructed, arranged, and

5 ters Patent, isoperated as set forth.

In a Wind-wheel having the pitch of the blades automatically controlled by the face- JOHN M'. BARNES' pressure, the independent hub y, sliding longi- Witnesses: tudinally ou the main shaft, and engaging H. J. PATTERSON, to with a Weighted lever, L, and the independent W. S. PALMER.
