Beit -kno'wn that I, BEn'rlE EUGENE CAS- sELL, a citizen of the United States, residing at Sparland, in the county (if-Marshall and State useful Improvement in Windmills, of which is a specification. My invention relates to wind mills; and it has for .one lof its objects to provide a wind mill in which .the 'drivin connection for transmitting motion from t e wind wheel to ated is entirely inclosed `,and pnotected from the weather with a view of prolonging the4 usefulness of the i j Another object ofthe invention is the provision of roved means for automatically 'wind-w Aeel and connection of a wind when' the wheel 1s 'thrown out of the Other advantageousl features .peculiar to' my invention wil be .fully understood from the following' description and claims when the samev arey considered connection with .Figure 1 is` an elevationjpartly in section, of my improved wind mill as the same ap pears when the wind mill is out `of the windl Fig. 2 is a detail topplan view illustratin the housing of the mill and the vane pivote to said housing.

Fig. 8 is an enlarged, detail eleears when the wheel is put in ig. 9 is an enlarged elevation of Referring by numeral tothe said drawings and more particularly to Figs. 1 to 7, thereof:

conventional or any other construction com.- patible with the purposes of my invention.

2A is a pump which is represented 'as an ei@ ample of device to be actuated and is provided with the usual piston rod 3, and 4'is the'.

before mentioned rotatable su port for the drivin connection, as a who e. The said notata le support 4 comprises a housing-l 5, supported and adapted to turn on its axis on the top of the frame 1 and having a removable door 6 to permit of access being 'readily gained to the parts which it incloses,'and also' having a lateral sleeve .7 extending fromy a point opposite the door v6, a tube 8 communil' eating 'with the interior o fand depending` from the housing 5 and occupying the -verl tical center' of the frame 1, a section'9 having a split, tubular upper portion 10,. fixed in the lower end 'of the tube, 8; and a section' 11,

-boltrd at 12, Fig. 6, to the section 9 vandhav- -ing an enlargement 13 bearing on a stendardi 14 rising from across bar 15 ofzframe 1 andl also having a depending tube 16 journaledin said standard 14 and cross bar 1 5. u 17 vis a shaft journaled in the sleeve 7 'ofthe ihousing 5. At its outer end this shaft I17' has fixed on it a wind Wheel 18, of the conven'- :tional construction or anyother construction suitable to the manufacturer, while onits inner end is xed a peripherally grooved pulley 19, Fig. 3, which is contained in the housing 5 and is arranged opposite the door 6, as shown :in l l I 2O is a peripherally grooved pulley, fixed on a shaft 21, journaled in the section 11 the rotatable support 4. 1

22, 22 are anti-friction and guide sheaves mounted in the lower portion of the housing 5s 23, 23 are anti-friction and guide sheaves mounted n the section 9 of rotary support 4, and 24 is a belt, of rope, chain or other material suitable to the urpose, mounted oil and connecting the p leys 19 and 20 and arranged-in engagement with the sheaves 22 and 23 after the manner shown in Figs. l, 4 p

and 6. In virtue of this construction it will be observed that when the wind-wheel 18 is the tube 8, and that the housing 5 and tube 8' inclose the pulley I9 and belt 24 and effi# v cientl protect the same against the weather;

It wil further be observed that the support 4-l A as a whole is freeto turn on its axis 1n the .40 to which the ca frame 1, and hence will not interfere with the wheel 18 being put into and out of the wind, as will be presently described.

25 is a hood fixed to the frame 1 and loosely surrounding the tube 8 in a position slightly above the ulley 20 and sheaves 23. hood has or its' othce to protect the said sheaves and pulley from rain, snow, etc. 26 is a pitman pivoted to the side of the pulle 20I off the center thereof, and provide at lts lower end with amanti-friction Wheel 27 which is movable up and down in .thetube 16..

28 is a rod pivotally connected to and clepending from' the lower end of pitman 26, and 29 is, a rod xedly connected to the rod l 28 andconnected throu h a swivel joint 30 with the ump rod 3. rom this construction it follbws that when the wind wheel is in operation, the rotary motion of the pulley 2O be converted into reciprocatory motion and utilized to actuate the pum rod 3. At this point I desire it understoo that when deemed expedient or desirable rotary motion may be ta en fromthe'shaft 21 of pulley 20 to actuate machine of various kinds.

. 30. is a horizonta y swinging vane, pivot- .l ed at`131 to the housing 5.

32 is a tractile spring interposed between- `mths-housing 5 and the vane 30, and having i 'for its function to draw the vane to and nor- A-mally hold the saine in a position at a right angle to the Wind wheel -18 and against a brace arm 33 fixed to the housing 5 so as to 35 put and retain the Wind wheel 18 in the wind. 34 is a cable connected to the vane 30 and passed over a sheave-35 which hangs on a swivel on the housing and down through the hollow, rotary suiplport 4, and 36 is a windlass e 34 is connected and on which it is designed to be wound; the said ,Windlass being provided with' a ratchet which `is englaged by a pawl aslshown to prevent casu retrograde rotation of the wmdlass.

It will be apparent that when the windlass 36 is turned in the direction towind up the cable 34 the vane 30a will be drawn toand retained in a position arallel t the wheel 18 and in consequence t e wheel will be moved and held out of the wind..

With a view of braking or gradually stopping the wheel 18 and the driving connection intermediate the same and the pump rod 3 when the wheel 18 is ut out of the wind, I provide the rod 37. his rod is mounted in the housing 5 and its inner end is arranged to bear against theface of the pulley 19 while its outer end is arranged to he engaged h a portion of the vane 30, Thus when t e vane 30'is moved to a position to put the wheel 1S out of the wind,it will press therod 37 in# ward, and by `so doing will cause'said rod to, frictionally engage the pullev 19 so as to bring said pullev and the wind wheel and the belt other than those shown and described y 55 parts connected therewith to a gradual s top.

-Onthemovernent of the vane 30a to a position at a right an le to the wheel 18, the rod 37 will obviously e relieved of pressure, and the pulley 19 will be left free to turn. t

In the modified construction' shown in Figs. 8 and 9, thevvane 30lvl is, through the medium of a tractile spring 32, drawn to and held in a position parallel to the wheel 18 and' so as to press the rod 37 against the pulley 19 i for the purpose before described, while the vane is moved to and retained ina position at a rightang'le to the wheel 18 and against the brace'arm 33a through the medium of a cable 34 which is connected to the vane and the windlass 36 and is passed over a sheavc 3521*" s. 8 and 9, and through an aperture in the ollowvrotary support 4 and is contained in said su port 4.

It is obvious that in practice pulleys and a and suitable to the purposes of my invention Vmay be employed 1n-the discretion of the manufacturer without involving de arture from the scopeof my invention as c aimed. I also desire 1t understood that when deemed necessary a suitable fender 40 may beamploed for holding the cable or chain 34' attac ed to the windlass 36 against becoming. entangled'in the lower pulle 20. It will begathered from tlie foregoing that vboth embodiments of my invention are simple and compact in construction and at theA same time are well ada ted to withstand the usage to which Wind mPlls are ordinarily subjected. i

The .constructions shown and described constitute the preferred embodiments of my invention, but I desire it understood than in practice such changes in the form, construetion and relative arrangement of partsmay `195 be made as fairly fall wlthin the scope of my claimed invent-ion.

Having described my invention, what I claim and desire to secure by Letters Pat ent, is:

1. A windmili comprising a frame; a hollow rotatable su )port mounted in said frame and carrying a housing at its upper end; a windwheel journaled in said housing; a. ulley in said housing adapted to he rotate l)by said win'dwlieel; a vane projecting from 4the opposite side of said housing; a split tubularf section carried by the lower end ofsaid rotatable support und terminatingfin a flat open section; a tubular section mounted in the lower portion of said frame and having a projectinpr flat open portion that ist' connected with the o en section of the split tubular portion; a pulley mounted in theflat open pro- 'ecting portion ofsaid lower tube, and a ca- 125 le connecting the said two pulleys.
