UNITED STATES PATENT OFFICE. v

J. C. VILSON AND TG. VILSON, OF CEDAR I-IILL, TEXAS.

IMPROVED`METHOD OF FEATHERING THE SAILS OR VANES OF WINDMILLS.

Specication forming part of Letters Patent No. 16,943, dated March 31, 1857.

To all whom, t may concern.-

Be it known that we, J. C. WILSON and T. G. WILSON, of Cedar Hill, in the county of Dallas and State of Texas, have invented a new and useful Improvement in Wind- Wheels; and we do hereby declare that the following is a full7 clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, forming part of the same, in which Figure l is a face view of the Wheel. Fig. 2 is a section through axis of shaft, showing one win g and rods connected therewith. Fig. 3 is a view showing action of springs upon the wings, one wing, a section of shaft, and a portion of the rim being shown.

Similar characters of reference in the several iigures denote the same parts.

The nature of our invention consists in a means of bringing the edges of the wings to the wind for the protection of the wheel during storms.

In the drawings, A is the main shaft placed horizontally and geared with the lnill-shaft in the usual manner.

W IV are `the wings, each movable upon one of the arms a, radiating from the shaft A. These arms are held firm by braces b. The wings are all connected by rods c with the slide-piece cl, movable between stops e and j' on spindle g. Behind each wing is a spring 7a., with a roller fr' in vits extremity. These springs'are fastened upon a rim k, secured to arms ct, and are regulated in strength by screws Z.

In the extremity of the shaft A is inserted a screw m, which when moved outward will carry stopf against slide-piece d, so as to produce the movement of said slide in direction of the axis of the shaft, and by drawing on rods c turn the edges n of the WingsV in direction of the said slide-piece. The springs h are of suflicieut strength to resist the pressure of wind necessary for turning the wheel, and when a sudden aw occurs they will yield temporarily to the pressure thus exerted against the wings and force the wings to resume rheirposition when the increased pressure is removed. The slide-piece d moves along spindle g during the aforesaid. action.

XVhen storms occur, the crank q is held by the miller, causing the rotation of the wheel to produce the outward movement of the screw m, which, acting on rods c, will draw the edges 'nof the wings in direction of the outer extremity of the shaft A and cause the wings to lie in planes passing through the axes of arms o andmain shaft A. The wind will then be able to act on their edges only and no damage to the wheel ensues.

What we claim, and desire to secure by Letters Patent, is

The combination of the traversing screw m, having stops e and f, as described, with the slide-niece, and rods leading to the wing, the construction and arrangement being substantially as and for the purposes described.

In testimony whereof we have hereunto signed our names before two subscribing witnesses.
