WINDMILL.

SPECIFCATION forming part ci' Letters Patent No. 339,715, dated April 13, 1886.

Application filed January 531, 1886.

To all whom it may concern:

Be it known that I, GEORGE TURNER, a citizen of the United States, residing at Kalamazoo, county of Kalamazoo, State of Michigan, have invented a new and useful Power-findmill, of which the following is a specification.

The object of this invention consists in the improved means of connecting working machinery to be driven by a single vertical rotatable power-shaft of a windmill with said shaft, substantially as below described and claimed, to prevent the resistance of the working machinery from causing the windwheel to creep out of its true position in the wind.

In the drawings forming apart of this specication, Figure l is an elevation, with the mill-head and tubular pendant in vertical section; Fig. 2, asection on line 2 in Fig. 3; Fig. 3, atop viewof the detail shown in Fig. 2 and Fig. 4, a part of Fig. 3, referred to by like letters.

Referring to the letters marked on the drawings, B is an ordinary mill-head,with tubular pendant E, having swiveled bearings in the cap of the derriek F, in the usual manner. The horizontal wheel-shaft D has bearings in the mill-head, and is provided with a rigidlysecured gear, a, which meshes with the gear c at the top of the vertical powenshaft fr. The pendant E has a vertical tubular eXtension, f, through which the power-shaft@1 passes. To the lower end of the extensionfis rigidly secured a laterally extending pinion support, It, or bridgetree. The outer end is turned under and forms an upper and lower bearing for the pinion C, Fig. 1. The lower end of the power-shaft?I has apinion, A, meshing with the pinion C.

When the wind-wheel rotates, motion is transmitted from the wheel-shaft to pinion C. It will be observed that when the mill-head turns in its swivcled bearings in the top ofthe derrick, which is caused by the wind-wheel shifting in the wind from one point of the compass to another, the pinion C is swung around to a greater or less degree, describing some portion of a circle, according to the distance the mill-head turns; hence said pinion C is always in meshing relation with the gear A of the power-shaft fr.

It is desired that motion be transmitted from Serial No. 1E9,l77. (No model.)

axle of the pinion O with the axle of the pinion t by means ofa flexible shaft, P. I term this shaft llexible77 because it performs the function in this construction which a flexible shaft proper would perform, and hence such. latter shaft might be employed. The shaft P has double joints at each end at right angles to each other, enabling it to yield and swing in all necessary directions. The square end of the rod P adjustably slips in and out in the joint a', Fig. l, thus enabling the shaft to lengthen and shorten when necessary. To illustrate: if the gear t were not inline with the vertical axis of the power-shaft r, then it would be necessary that the shaft r be capable of lengthening and shortening.

During the operation-the upper end of the shaft P follows the sweeping movement of the pinion C when the wheel changes in the wind. At the same time the connected pinion C, shaft P, and gear t rotate together, imparting motion to the machinery having the fixed bearings below the same, as though the pinion C had iixed bearings, and it was not necessary for the wind-wheel to shift in the wind.

In Figs. 2 and 3 it will be seen that the pinion-support R has an oileup, u, formed in the top, with oil-passages e e leading to the bearing of the shaft lr and to thc upper bearing of the pinion C. By keeping the cup u filled with oil these bearings are alwayslubricated. Other details and general operation of powerwindmills are well understood without further description here.

Having thus described my invention and its relation and operation with ordinary powerwindmills, what I claim as new, and desire to secure by Letters Patent of the United States, 1s-
