Specification of Letters Patent.

v Application filed November 7, 1906. Serial No. 342.342.

Windmills; and we do declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it appertains'to make and companying drawings and the characters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in wind mills, our object being to produce a simple and efiective wind mill, in which all the power generated by the wheel of the mill will be utilized without any lost motion or any unnecessary gear also one which may be easily handled; and lastly one provided with a simple automatic lubricator. These objects we accomplish by means of an endless gear suitablyconnected to a driving shaft, and means connected with said endless gear for operating the lifting rod; also by.

v such other and further constructions as will ing to the right.

appear by a perusal of the following specifications and claims.

In the drawings similar characters of reference indicate corresponding parts in the several views.

Figure 1 is a side elevation of our improved device with a portion of the casing broken away. Fig. 2 1s a section on Y Y of Fig. 1.'

Fig. 3 is a section on line X X of Fig. 1 look- Fig. 4 is a similar section looking to the left. Fig. 5 is a section taken on a line Z Z of Fig. 4.

1 designates the frame beams of the mill which uphold a turn tableconsisting of base members 2 which are formed with two tubular members 3 and 4, one within the other, leaving a space 5 therebetween, in which space 5 a tubular support 6 is arranged, said su ort 6 u holdin the gear box 7 of the r P b m1 This gear box 7 is formed of a cast box divided into two oval chambers 8, the upper one of said chambers 8 opening into a chamber 9, which chamber 9 is connected with the tubular suppoYt 6 by means of a semi-tubular member 10. In said chamber 9 is arranged the lifting rod 11 extending through the member 10 and 6 and provided with a slotted cross head 12. 13 is asmall pinion wheel secured on the shafaof the mill within the box 7 at the center thereof, and intermeshing with an endless rack gear 14 secured to a bar 15, which bar 15 is pivotally secured to rollers 16 which bear against the sides of the chambers 8. At the upper end of the bar 15 opposite to the roller '16 is a small roller 17 which extends into the slot in the cross head 12,'for the purpose as will appear. Bolted lates 8 provide openings into the chamers 8.

In practice the rotation of the wheel of the mill rotates the pinion wheel 13 which, intermeshing with the gear 14, drives the bar 15 and rollers 16 around in the chambers 8, thus giving vthe same an up and down stroke, and since the roller 17 operates in the slot of the'cross head 12, this gives the lifting rod 11 an up and down reciprocating movement as is required,

Another valuable feature of our invention is that it may be automaticall lubricated as follows :-The lower one of t e chambers 8 may be filled with lubricant. As the bar 15 and its parts make their movement they pass through the oil and carry a sufficient amount upward to lubricate all the gearing. To lubricate the shaft of the mill we run a pipe 24 from the lower end of the upper chamber 8 to the shaft box, and a pipe 25 leads from the outer end of the shaft box tothe lower chamber 8 for the P111)0S6 of returnin the surplus lubricant. Tie lower end 0 the lower chamber 8 is formed of a movable member 26, the position of which is regulated by means of set screws 27 for the purpose of taking any possible wear.

u 18 indicates tlie usual frame for the vane 18, this frame being carried b brackets 20, 20? carried by the casing 7 an the casingof chamber 9 res ectively; This frame is shiftable to pull t e wheel out of the wind by means of a cable 21 attached at one end to the frame and then passed over pulley 22 carried by the casing of chamber 9, over a pulley 23 within upper chamber 8 and down throu h members 10 and 6 to the tail lever (not filOWII) at the foot of the mill. As the particular manner of shifting this frame is not a part of the improvement embodied in the casing 7, further detailed description is believed to be unnecessary as the specific construction of these parts is not dependent upon the construction of the mechanism herein claimed.

Thus it will be seen we have produced a wind mill in which the power of the wheel is a cure by Letters Patent is all utilized, the endless rack gear 14 preventing any loss of power; also a mill which is easily constructed and handled; and lastly one which may be automatically lubricated by a simple and inexpensive means.

This description embodies the present and preferred construction of the device. However, in practice such construction may be changed slightly from its present form, but such changes Will not of course depart from the spirit of the invention.

Having thus described our invention, what we claim as new and useful, and desire to se- 1. In a wind niill, a casin having spaced interior guide chambers, a (I naled in said casing and carryi a, gear wheel 0 crating between said gui e chambers, a ame having rollers for operating in said guide chambers and with a laterally extending operating roller, an endless gear rack carried by said frame and operatively engaged by said gear, and an operating rod aving a transverse slot and ada ted to be engaged by said lateral bearing ro ler.

2. In a device of the class described, .a casing having elongated interior chambers spaced apart and with rounded ends and with a lateral chamber communicating with one of said elongated chambers, adrive shaft journaled in said casing between said chambers and carrying a gear'wheel, a frame havrive shaft jour-' ing rollers for operatin in said guide chambers and with a lateral I earing roller extending into said laterally communicatin chamber, an endless ear rack carried Ly said frame and operatively engaged by said gear,

and 'an operating rod movably disposed in said lateral chamber and provided with a transverse slot adapted to be engaged 'by said lateral bearin roller.

3. In a Wind mil, a casin having spaced elongated uide chambers aving rounded ends with t e outer end of one of said chambers adjustable longitudinally thereof and with .a lateral chamber communicating with the other of said elongated chambers, a shaft provided with a gear operating between said elongated chambers, a frame havin rollers operating in said guide chambers an With a bearing roller extending into said lateral chamber, an endless ear rack carried by said frame and operative y engaged by said gear, and an operating rod movable in said lateral chamber and having a transverse slot adapted to be engaged by said lateralv bearing roller.

In testimony whereof we aifix our signa tures in presence of two Witnesses.
