WINDIVIILL.

SPECIFICATION forming part of Letters Patent No. 392,217, dated November 6, 1888.

Application filed January 5, 1888. Serial No. 259,856. (No model.)

To aZZ whom, t may concern:

Be it known that I, CHARLES M. MOORE, a residing at Rupee, 1n the county of Falls and State of TeXas,have invented certain new and useful Improvements in Windmills; andl do hereby declare that the followingis av full, clear, and exact description of the invention, which will enable others skilled in nthe art to which it appertains to make and use the same.

This invention relates to that class of windmills in which semicircular wings are employed upon a vertical shaft; and it has for its object to provide simple and efficient means to govern the speed of the same, and also to throw the windmill into or out of operation when desired, as will be hereinafter described.

A further object of the invention is to provide a windmill of the above-mentioned class which will possess meritin point of durability, inexpensivencss, and general efficiency.

In the drawings, Figure l is a front elevation of a portion of a windmill provided with my improvements. Fig. 2 is a similar View showing the device thrown out of operation, Fig. 3 is a top or plan view, part of the frame being broken away to show the construction. Fig. is a perspective View of the top pair of wings removed from the shaft. Fig. 5 is a perspective view of a modified form of wing. Fig. 6 is a sectional View of the same, the op` eration being illustrated in dotted lines. Fig. 7 is a detail perspective view of thelower pair of collars.

Corresponding parts in the figures are denoted by the same letters of reference.

Referring to the drawings, A designates a frame composed of two parallel vertical beams, A A, connected by a top and bottom crossbeanl, B B', respectively, and journaled in said cross-beams is a vertical shaft, C. Upon this shaft is rigidlyinounted a collar, D, having an inclined upper end formingashouldend, and resting upon said inclined upper end is a correspondingly-inclined lower end of a collar, E, loosely mounted upon the shaft, said inclined end having a shoulder,.e, engaging the shoulder d on the collar D, as shown in Fig. 7. Above the collars D and E, loosely mounted on the shaft, are two similar collars, Fand G, respectively, the collar F having a sli ghtly-inclined lower end, forming a shoulder, f, engaging a pin, f', on the shaft. Upon the colla-rs D, E, F, and G are respectively secured in any suitable manner semicircular wings D', E', F', and G', the said collars being disposed upon the shaft in such manner that the upper pair of wings Will be in transverse relation to the lower pair.

H designates a sleeve or collar mounted upon the shaft above the series of collars and having vertical movement thereon. The sleeve II is provided with a circumferential groove, 7L, near its upper end. A lever, I, hinged upon the beam A,hasan enlarged circular portion,,having an opening in its center. The portion i is seated in the groove h,by means of which construction the sleeve H can be moved vertically upon the shaft. The lever I is extended through a slot in` the beam A,and said extended portion has a series of notches, t', upon its upper edge. A weight, I, having a loop, fi, embracing the lever I, is provided upon the end of the said lever, the purpose of which will be hereinafter described.

J designates a rope or chain attached to an eye, i, upon the lever I, and is then passed over a pulley, K, upon the top beam of the frame and down to where it can be readily operated.

To operate the wings a rope or chain, L, is secured at one lend to the lowermost collar, D, then passed through a staple, e',on the adjoining collar, E, overa pulley, M, secured upon the sleeve H, then through a staple, f,on the collar F, and the free end is secured to the collar G. Upon the shaft C, above the bottom pair of collars,D E, I prefer to provide a coiled spring, S, for the purpose of normally retaining the collar E down against the collar D and to prevent vibration of said collars while in motion.`

Upon the under side of the crossvbeam B are provided two brackets, W WV, in one of which is journaled a horizontal shaft, V, provided at one end with a crank-arm or device, U, for communicating motion to the pistonrod of a pump or other mechanism adapted to be operated. Motion is imparted to the horizontal shaft through the medium of a bevelgear, T, connecting the same with the vertical shaft C.

ICO

The operation and advantages of my invention will be readily understood by those skilled in the art to which it appertains. XVhen it is desired to throw the windmill out of operation,

5 the rope or chain .I is pulled down, thereby raising the lever I, together with the sleeve H, and also pulling the rope or chain L, thus drawing all the wings to one side ofthe shaft and causing them to drift in the wind. It is also manifest that during a strong wind the force of the wind will cause the collars on the adjoining inclined ends of the said collars to wind upon said inclined ends, thus producing the same result as that above described. The strength of wind necessary to throw the meehanism out of operation is regulated by the weight upon the lever I by moving it nearer or farther from its hinged end, as required.

In Figs. 5 and (i I have shown a wing of modiied construct ion, consisting ol the collar N, having a vertical arm, I, extending therefrom, to the end of which isseenred the wing O at about onelhird its length from the inner end by means of a spring-hinge, o. If desired, I may employ a rope or chain, O', secured to a staple, o', in the wing, and passed through a staple, o, in the collaro'f said wing, and from thence to the sleeve II at the top of the shaft C. rI`he operation of this forni of wing is manifest. \Vhen the force of the wind is great, the wings are automatically forced out of their normal position and draw upon the tension ofthe spring-hinge, thus allowing the surplus wind to pass, and when the wind 5 is modified the wing seeks its normal position. It will be obvious that the speed of the wing is automatically governed by the action ofthe spring-hinge. By means of the rope or chain O the wings may be drawn back and out of operation at will.

I do not limit myself tothe number of wings employed, as there maybe a greater or less number used when so desired.

'l` claim as my inventionl. rIlhe combination, in a windmill, of an upright whcelsshaft, and a series of collars disposed on said shaft having sails secured thereto, said collars being arranged in pairs, having correspondingly inclined adjoining ends, whereby when great force of wind is exerted on the wings the collars will automatically turn upon their inclined ends, throwing the wings upon one side of the shaft and out of operation, substantially as set forth.

2. rIhe combination, in a windmill, of a frame, a wheel-shaft journaled therein and having collars disposed thereon, sails secured to the collars, said collars having correspondingly-inclined adjoining ends, asleeve mounted on the shaft above the collars, and a lever hinged at one end and having an adjustable weight suspended at its other end, Said lever, in conjunction with the sleeve, being adapted io exert a pressure upon the collars, whereby the sails upon the collars will be retained in normal position, except when great force is exerted upon the sails, substantially as set forth.

fi. The combination, in a windmill, of a wheel-shalt having collars disposed thereon, said collars being arranged in pairs and having inclined adjoining ends, arms projecting from the collars and sails secured thereto, and a coiled spring provided upon the shaft bctween each pair of collars, substantially as set forth.

4. rIhe combination, in a windmill, of a wheel-shaft, collars disposed thereon having correspondingly-inclined adjoining ends, and arms projecting from said collars having spring-actuated sails pivoted thereto, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
