These. shafts each other, and firmly secured in this position to the est width of vane will be below the spindles, the upper f sides being weighted so as tobalance them upon the shaft. This gives the wind a chance, when it Astrikes `the vanes squarely, of causing them-to turnby acting i j them to turn as soon as'one side is relieved of the force of the wind and the other' meets it. y

IMPRovMENT 1N WIND-WHEELS.

The Schedule referred to in these Letters Patentand making part of the same.

To all whom it may concern v i Be it known that I, CHARLES MAHLER, of the city declare the following description and accompanying drawings aresucient to enable any person skilled in the art or science to which it most nearly appertains to make and use-my said invention or improvements, wit-hout 4further invention or experiment.

My invention relates to an improved wind-mill, which may also, when divested of aiportion of its regulating parts, be employed as i a water-wheel for driving ma chnery, or as a propeller-wheel for vessels floating in the water; and i l It consists in providing transverse slots in the vanes sides of the arm may be varied las desired.

mounted above the mill-frame, so as to operate the devices for controlling the speed of the wheel.

In order.v to more .fully illustrate and explain my invention, reference is had to the accompanying drawings, forming a part` of this speoifcation,in which- A A represent two vertical' posts, having the plate any other suitable flame can be used. p

C is 4the vertical shaft which supports the mill, and

D, between the two posts A A, and passing through Secured upon' thel upper end of the upright shaft C is a box, E, which may have its sides entirely closed or.,a portion left'open, as shown, for adjusting any ranged.

Passing through the sides of this box, at right anextend a considerable distance from theA sides of the box on each side, and have secured upon their op` posite ends the vanes or` sails G, the' two opposite vanes on each shaft heilig placed at right angles tol shaft. .i

.The vanes are secured'upon lthe opposite ends of the shaftsor spindles in such a manner that the great upon the lower part, where` there is t-he greatest leverage, thus feathering the opposite vanes, so as to cause Transverse slots, a, serve to render the vanes adjustable in order to vary the weight.

Inside the box the spindles have an elongated lug or projection, b, formed on them, which serves to stop the revolution of the shaftwhcuit turns to the proper position in feath'ering the vanes.

' Secured to the sides of the box on each side of the spindles, and with their widest end uppermost, are, `wedge-shaped blocks, 1, having their inclined sides facing the spindles. A block, J, similar in form, is placed with its narrow end uppermost, so that both inclined surfaces will lie in contact, the two blocks forming a square.

The inclined surfaces of there blocks are corrugated, as shown, in order that when the lug 7J on the spindle strikes the block J the corrugations will lock the two together, and prevent the block Ifrom slipi ping. l

A suitable guard, d, is arranged beneath the sliding block I, so as vtoprevent it from being displaced.

.Extending upward from the top of the box is a spindle, K, to the upper end of which are attached four arms ot' a governor, L, each pair being connected with the movable blockJ ot' each vane-shaft by means of the rodsf.

These governors prevent the wheel from running at too high'avrate of speed, should the wind blow very strong, by raising the blocks J, and thus preventing the vane-shafts from tuming suiicentlyto allow the wind to strike the full face ofthe vane.

When in operation, the vanes as they come around against the wind lie horizontally, so as to present no smface for it to act against, while the one on .the opposit-e end of the shaft stands vertically, receiving the full force ofthe wind until the former comes to a po` sition where it Jcatches the wind, when, on account of the weight being ou the `under side of the shaft, it will turn until the projection 1b strikes the `block J on the opposite side, changing the position of the two opposite vanes.

This operation is'cont-inued as long as the wind is steady; but should it increase to a gale, the arms of the governors will y out and raise the block J, thus causing'the vanes to stand at .an angle to theuvind, in

which position'it has less power against them, and

consequently the speed is reguiated. The wheel above described can also he mounted vertically, in which case the governors would be, dispensed with, the vanes feathering automatically, owingto their peculiar construction.

, When used 'as a water-wheel or propeller for vessels, the wheel will kbe entirely submerged, the same action taking place in the water as` previously def scribed in the case of a wind-mill.

Havingr thus describedmy invention,

What I c1aim,and desire to secure by Letters Patent, 1s-

1. Regulating the speed of the wheel by means of the two inclined hloeks I and J, whose inclosed surfaces are corrugated, as described, and the `lug or projection b on the shait F, in combination with the governor L, substantially as herein specified.

v 2. The slots a in the valles G, whereby the relative widths of the partson opposite sides of the arms are made variable, substantially as and for the purpose set forth.

/ In witness whereof I have hereunto set my hand and seal.
