IMPROVEMENT IN WIND-WHEELS.
Hghl The Schedule referred to in these Letters Patent and making part of the same.
To all whom t may concern Be it known that I, WILLIAM M. PIPER, o f Blue Earth City, county of Faribault, State of Minnesota, have invented certain new and useful Improvements in Wind-Wheels; and I do hereby declare that the following is a full, clear, and exact description of the same,.reference being had to the annexed drawings, and to the letters of reference marked thereon, making part of this specification, and in which- Figure I is a plan View.
Figure 2 is a side view of the windwheel and gates, showing the connection of the levers and governor therewith.
The nature of my invention consists in constructing a wind-wheel with adjustable gates or doors, which may be closed entirely, or -opened to any desired distance, according to the quantity of wind necessary for its successful operation.
Also, in attaching to the wind-wheel, by means of levers, a governor, these levers being so arranged that the wind-wheel works automatically, regulating itself the quantity of wind necessary.
To enable others skilled in the art to make and use vmy invention, I will now proceed to describe its coustruction and operation.
A and A1 arc the top and bottom plates, supporting the wheel and gates.
A2 A2 are thc blades of the wind-wheel.
B B are the gates.
b b are the hinges upon which thev gates turn.
b b' are the rods, which are pivoted at one end to the top and bottom ofthe gates B B, and at the other end to the plates C C.
lhese plates G C are fastened at their centre to the main drivii'lg-shaft D ofthe wind-wheel, and are each provided with a segmental rack, c, into which works the pinions c.
These pinions cI c are attached to a spindle or rod, E, having its bearings in the plates A and A1,..
This spindle or rod is provided at its lower end with a crank, c, which works in a slot in the lever F.
This lever F is connected with the bell-crank lever F1, which has its bearing on the pin f, and is connectcd with 4the governor Gr, by means of the levers I1 2 F". v
'lhe lever FJ has its fulcrum in the slot of the upright shaft f, and is foi-med at one end with a bifurcated arm, on each branch of which is a small projecting pin, which works in the groove el, in a circular plate on the shaft of the governor, and which is connected by rods with the arms of the governor, and
rises and falls with them.
H is the shaft of the governor, on the lower end of which is a pulley, h.
Thispulley h is connected, by means of the cord h',
with the pulley la?, on the lower end of the main driving-shaft D of the Wind-wheel.
The operation is as follows:
The gates or doors being open, the wind passes through them, and, striking against the blades of the wind-wheel, causes it to revolve. This motion is communicated to the pulley h2, and by means of the cord h, to the pulley h and the governor G.
Should the wind be too great or irregular, the motion communicated to the windwheel being almost instantaneously communicated to the governor,will make it revolve rapidly, and thus cause 'the circular plate, on which the groove l is formed, to rise, depressing the handle ofthe lever F, and by this means causing the bell-crank lever Fl and the lever F to operate upon the crank c2 and spindle E, which, in turn, moves the plates C C, by means of the pinions cl and the segmental rack c, and thus, by meansof the rods 11 b', cause the doors to partly close.
rIhus, it ,will be observed, that the motion of the wheel is rendered always regular and equable.
The gates have brackets at each end, which serve the purpose of holding the wiud;and not letting it pass above or below the gates. The sectors in the wheel also serve a similar purpose.
The wind-wheel may be reversed, so that the crank c2 will be applied to the upper instead of the lower frame, and all the peiatingmeclianism that connects it with the governor will operate from above instead Having thus fully described Vmy invention,
What I claim therein as new, andv desire to secure by Letters Patent of the United States, is
The blades A2 A2, gates B B, plates G C, rods b b', segmental rack c, and pinion-wheel c, when the same are so connected with the' governor by a system of leverage as to be rendered self-adjusting, and thus be enabled, .through its own operating mechanism, to regulate the amount of wind that is to be admitted to the wheel, the whole being so combined and .arranged as to operate substantially as described, as and for the purpose specified.
In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
