l IMPROVEMENT IN WINDMILLS.

Specification forming part of Letters Patent No. 18 1,293, dated August 22, 1876; application filed May 24, 1876.

To all whom it may concern:

Be it known that. I, GEORGE H. WAL- LACE, of Newton, in the county of Jasper and State ofIowa, have invented certain new and useful Improvements in Windmills; and I do hereby declare that the following is a full, clear,and exact description thereof', which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specication.

My invention relates to improvements, in windmills, of that class in which the windwheely rotates on a vertical axis, and is surrounded by a series of shutters, which may -be closed to shut off the wind entirely from the wheel, and opened to act as directrices for the wind to the wheel, and the invention consists in certain new and improved devices and combinations of devices, whereby the operation of the wind-wheel is rendered more effective and easy to regulate, all as hereinafter more fully set forth.

In the accompanying drawing, Figure 1 is a side elevation of a windmill embodying my invention. Fig. 2 is a sectional view in the line w of Fig. l. Fig. 3 is a sectional view in the line y y in Fig. l, looking upward; and Fig. 4is a section through one of the shutters, and its hinge.

Referring to the parts by letters, letters A represent the frame-work of the structure on which the motor rests, consisting of posts A and transverse frame-pieces A A A. B is the wind-wheel, mountedon a central vertical, B', having suitable bearings in the bars Al A", and carrying sails b, as shown plainly at Fig. 2. C O are annular plates, secured to the frame-piecesl A A", the one, O, above, and the other, O', belowthe wheel B. D represents the shutters hinged at d on their inner edges to the plates O O', the lower hinge formed, as shown at Fig. 4, of a journal, d', which enters the lower end of the shutter, a collar, d, on which the shutter is supported, and an end, d, which enters the plate O. The shutters D are hung so that their inner edges come very near the periphery of the wheel B, and, being hinged very near their edges, changing their angle does not affect their distance from said wheel; hence, opening them at a greater or less distance does not increase the annular space-between them and the wheel, and thus open a passage for the air inoperative upon, the wheel. E is a circular plate, journaled on the shaft B above a collar, F,

which is secured upon the shaft by a set-screw,

f. Letters e are arms or rods, pivoted at one end in the plate E, and their other ends pivoted one to each lower end of the shutters D, so that rotation of the plate E will o-penfand close the shutters. G is an arm attached to the plate E, and extending outward beyond the supporting-frame A. EI is a pulley or wheel on the shaft B', on the periphery of which is a serpentine cam-shaped projection, h. I is an arm pivoted or hinged at one end to the side of the frame A, and its other end formed into a T-shaped head, t', carrying pulleys s s, between which the cam h operates, so that a rotary motion of the shaft B will impart an oscillating movement to the arm I, and through it transmit a reciprocating mo-A tion to a pump-rod, or any desired device connected with it.

By removing the cam h a belt may be used to transmit motion from the pulley H. The rod or arm G may be used to turn the plate E to entirely close the shutters, or to set and fix them at any desired degree of opening.

Having thus described myinvention, what I claim as new, anddesire to secure by Letters Patent, is

l. rlhe hinges for the shutters D, constructed as described, with a journal, d, collars d, and end df, for operatibn with said shutters D and plate E, substantially as and for the purpose specied 2. The cam-wheel H, arranged to operate y with the wind-wheel B and arm I, carrying studs s, with or without pulleys, substantially as and for the purpose specified.

In testimony that I claim the foregoing asl my own I affix my signature in presence of Witnesses TEos. A. MOKEE, H. E. HUNTER.
