IMPROVED METHOD 0F REGULATING THE VELOCITY OF WIND-WHEELS.

Specification forming part of Letters Patent No. 18,210, dated September' l5, 1857.

To all whom t may concern.-

Be it known that I, FRANCIS PEABODY, of Salem, in the county of Essex and State of Massachusetts, have invented a new and Tmproved Method of Regulating the Speed of VVind-VVheels, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification, in which- Figure l is a plan; Fig. 2, an elevation; Fig. 3, a perspective View of the disk behind the wheel.

My invention consists in the arrangement of a wind-wheel fixed permanently upon its axle in connection with a sectional disk behind it, the sections being hinged so as to be placed at a greater or less distance from the wheel, and furnishedV with a means of regulating this distance to suit the varying force of the wind.

In the accompanying drawings, A is the building or mill, to one corner of which the wheel is applied, and l), the wheel, which is permanently secured to its shaft and suitably stayed by rods C.

-The regulating-disk is placed immediately behind the wheel, and is constructed and operated as follows: To the vertical posts D (which are firmly attached to the building or otherwise suitably stayed and supported) are hinged the sections F of the disk. E are horizontal timbers, which are secured to the vertical posts D and lie in the plane of the disk when the sections are brought up immediately behind the wheel. G are cords or chains, which are secured to the sect-ions F, and, passing around rollers upon the timbers E, enter the building, where they are operated by Windlasses or otherwise, by which means the posivis erected upon a turn-table H, by which means the wheel may at all times be kept to the Wind.

The above-described arrangement and construction of the sectional disk puts it within the power of the miller to regulate the speed of his wheel not only to the force of the wind at the time, but also to the requirements of the work in hand.

wind. As the force of the wind increases, the sections may be drawn more or less near to the wheel, and in violent gales the motion of the wheel may be stopped by bringing up all the sections of the disk immediately behind the wheel, it being necessary simply to construct the disk of su flicient strength to enable it to resist the force of lthe highest wind to which it may ever be exposed.

What I claim as my invention, and desire to secure by Letters Patent, is-

An improvement in regulating the action of wind-Wheels in the sectional disk, operat ing in the manner substantially as set forth.
