SPECIFICATION' forming part of Letters Patent No.A 446,30*?, dated February 10, 1891.

Application led November I4, 1888. Serial No. 290,859. (No model.) i

To all whom, it may concern.-

Be it known that I, CHARLES O. WEIDMAN,

Montville, in the county of Medina and State of Ohio, have invented a certain new and useful Improvement in lVindmills, of which the following is a specification.

My invention relates to certain novel improvements in windmills, which improvements will be fully understood from the following description and claims.

Practically my improved windmill will be made of metal, although it will be obvious from the following description that certain parts may be made of other material.

In the accompanying drawings, in which similar letters of reference indicate like parts, Figure l is a perspective of my improved windmill with parts of the sails and vanes cut away; Fig. 2, a vertical section of the same through the central spindle at a right angle with the windmill-shaft; Fig. 3, avertical section through the line of the windmill-shaft, and Fig. et a perspective of the adjustable bracket to sustain the upper end-of the vanepivot.

VThe entire machine is Ysupported in the usual manner on a vertical hollow post A, on the top of which is a metallic cap B, having a central opening surrounded by a'raised rim to receive the central spindle, and is retained by two L-shaped bolts b l), one arm of each of which passes ont from the inside of the post A and is secured by a nut, the other arm serving to sustain the plate r, on which the central spindle rests, being held up andadjusted by nuts. By this device I avoid the necessity of two sets of bolts, one to sustain the plate and one to sustain the cap.

The working mechanism is connected with and supported on a head C, which consists'of a base substantiallya quadrant, having a cupshaped bearing fior the lower end of the vanepivot and an opening at, its inner angle'for the pump-rod and provided with upright walls on its straight sides, one of which supports a long bearing c for the windmill-shaft and a boss c', from which the crank-shaft projects. On the bottom of the head C is a shoulder d, beneath which depends a hollow spindle D, which enters the opening in the cap B and rests on the plate r. The lower I end ot' the vspindle D (imperfectly shown in Fig. 2) is beveled on the outside and rests on a boss on the plate'r, about which is a raised rim 7", leaving an intermediate annular channel/in which a supply of oil is placed to constantly lubricate the bearing. Immediately above the plate r is acollar q, held and adjusted by bolts through the post A, which retains the spindle D centrally in position. By

this arrangeinentI securea minimum of friction on the spindle, as it bears only on the plate lr, the rim of the cap B and the collar q serving simply as guides.

In the bearing C is journaled a shaft I, on

which is mounted the windmill or, to use a better expression toA distinguish it from the lentire apparatus, the wind-wheel, and at the inner end a crank t', connected with the pumping mechanism hereinafter described. On the shaft c is a hub H with a radial flange having radial grooves in which rest the sailarms s, wherethey are clamped by segmentall plates h, retained by bolts. This construction enables the wheel to be readily taken apart i'or transportation or repair. Upon the outer ends of the arms s are riveted sails S, and across the outer edge of each is an iron strap s', which projects beyond the sails and passes diagonally to the end of the strap of the next succeeding sail, thereby rmly uniting the outer edges of adjacent sails. On the outer end of the shaft I is a hub G, having a cupshaped flange perforated with a series of holes equal in number with the sails,in each of which is fastened a brace-rod g, which extends and is riveted to the upper end of one ot' the arms s, thereby prevent-ing the sail being bent backward by a violent Wind. Ona pin Z, projecting from the boss c', is pivoted a bell-crank Il, one end being united with the outer end of the crank by a link Z and the other with the upper end of the pump-rod P, which passes through the cent-er of the hollow spindle D. The pump-rod P is solid at the top, but hollow from a short distance below IOO resting in a similarly-shaped bearingj inthe lower face ot' -the bracket J, which is bolted to one wall ol' the head C and has a slotted bolt-hole by which itY is rendered horizon-` .a set-screw,and from the bottom of which projects a diagonal arm F, which affords a support for a brace c. rlhis brace fr rests in a socket in the end of the arm IP, and is united with the outer end of the vane-shaft c. By thus pivot-ing the vane its weight consta-ntly tends, as it stands in the line of the wind, to swing the head C on the spindle D,- so `as to bring the wind'wheel in the face of the wind.

Attached to the outer end lof t-hesleeve F is la :chain t, which passes `through the pulleys t t, attached to the walls of the head, and terminates in the wire w, hereinbefore referred to, which extends down the lpost A to a point where it can be readily reached. By'

diawingzthis Wire w the vane will be swung around parallel With ythe planeof the windwfheeland bri-ng the latter edgewise to the wind, so that it Will not be moved thereby. The bell-crank L is free to slide laterally ou the .pin yZ Ja short distance, and has on its sidel nearest their-ont wall ot' the head a butter o, Which engages the `wall when the bell-crank `is pressed inward.

On the armIWis abufferoQWhich encounters and presses the bell-crank L when the vane is swung .around parallel with the Wind- Wheel, therebyforcing the buffer o against the front wall of the head C, thereby constituting au 'effective brake to arrest further motion. l

Inoperation the vane, being in position at right angles with the plane of the wheel, holds the latter against the wind; but as the velocityof the wind increases, the wind-wheel being journaled at one side of the spindle D, will swingthe head around until the velocity decreases, when the vane, by the action hereinbefore described, will `turn it back, thus rendering the mill practically self-regulating.

I claim as my inventionl. The combination, in a Windmill, of a head with a depending spindle, a hollow post, a cap having a central opening to hold said spindle, a plate to forma step for said spindle, and bolts bent at substantially a right angle, their ends provided withfscreW-threads and nuts and arranged to pass, respectively, through said cap aud plate tol retain said cap on said post, sustain said plate, and regulate' its distance below said cap, substantially as shown and described.

i?. The combination, with the revoluble head of a Wind-mill having a fixed :bearing for the lower end of the vane-pivot, of au .ad-

justable bracket having an under bearing for y the upper end of said pivot to regulate itsi'inclination, and mea-ns, as a bolt, for uniting said bracket and head, substantially as shown and described.

3. The combination, in a windmill, of a revoluble head with a vertical WalL-a :bellcrank pivoted on Va pin projecting from said Wall to communicate motion from thewindwheel to the pu mp-rod and havingaboss to engage said Wall, and a pivoted vanearran ged to swing toward said bell-crank, having a butter to engage said bell-crank and force it toward said wall, substantially as' shown and described.

In testimony that I claim 'the aboveI hereunto set my hand.

CHARLES O. WYEIDMAN. In presence ot` v E. WV. STUART, F, H. STUART.
