This inventionfrelates to iinprovenients in windrni'llfconstr'uctions. 1 V

The priinary object of this invention 1s the provision ofl an i'n'iproved type of wndmil-l, embodying a nianually'` operated tnrblne -wheeh which may be conveniently andeffic'iently adjustedto Vperinit of the varlable V elosingl thereof, for i regulation ;to O btain yarious speeds of'rotation of'a driventshaft.

A further object of the inyention is the provisiou of a novel 'windniill construction einbodying a plural 'segmental cylindrical shapedl construction, the segments of'which may be relativelyadjust'ed'to provideran enclosed'cylinder, or which `lnay be laterally moved to provide vaines'having` various degrees of-extensjon, to perrnit the drive ofvan operated shaft at various speeds.

Other objects and adzantages of this invention will be a'pparent d'uringithecourse of'the following` detai'leddescription.

half Sections

24 and 25 are hooked 'in a sliding relation in the passageway of the channel 41. s a

Incident to the, above connection of the half cylinder sections'24 and 25 upon the upper and lower Channels and 41, it is readily appa-r-ent that said

half sections

24 and 25 may be slid along the channels 40 and 41, to position them in a true cylinder forming relation, or in laterally extended relation to open the pockets 34 and .35 of Vthe drawings. Upper and lower expansionisprlngs 55 `and 56 are provided for normally nrging 'said cylinder segment/

s

24 and 25, as is apparent from Figures l and 2 of the drawings. Of course, the channels 40 and 41 are ,greater in length than the diameter of the cylinder which is formed by the Sections 24 and v25, as is apparent from vFigure .5 of

i i the half cylinder Sections ;24 and 25 into an open extended relation to eXpos'e the pockets thereof; These springs and`56 are preferably'of the'V ordinary Spiral type, and at their ends they are connected by means of eye bolts or analogous expedients to the oppositel endsv of the

Sections

24 and 25, that is, 'one end of each spring` is connected to gone corner at the open pocket side of the one segment, and the same spring at'its opposite ends` is connected to a vdiainetrcally opposed corner at the open pocket side of the other segment, so that incident to the inherent tendencyV of the Springs, the

sections

24 and 25 will be forced in opposite directions along their supporting Channels, to

expose the ,openpocketed sides thereof, as

' illustratedin Figure v2 of the drawings.

- Referring to the means E by which the half '

cylinder sections

24 and 25 may be closed into a cylinder forming relation or by means of which they may be opened to Various degrees, to permit of theV shaft C to be driven at various Speeds, it is preferred to'provide a collar 60 in a splined relation upon the shaft C, at the end 20 between the upper and lower lsupporting Channels 40 and :41; this collar 60 having a narrow transverSe portion 61 extending at opposit'e sides of theaxi's of the shaft 20; and the portion 61 at one end being pivotally connected to a conn'ecting link 62 and at its opposite end being pivotally connected to a connecting link 63, preferably bymeans of eye bolts. The connecting

links

62 and 63 are of course disposed at opposite Sides of thel 'shaft C, and they are respcctively connected byzmeans of eye bo'ltsto the diametrically opposed sides of the

half cylindersections

24 and 25,,prefverably imm'ediately beneath the channel v40. lt is thus readily a-pparentithat if theycollar 00 is Slid downwardly upon the shaft end 20, incident to the connection of the

half sections

24 and 25 thereto, by means of the links ,62 Vand 68, the said half Sections or

cylindrical Sections

24 ,and 25 will be moved -towards each other into a 'cylindrical formation, asillustratedl in Figure 5.

` Anannular ring 67 is supported immediately at the top of the cap 12, beneath the llower wind wheel supporting channel 41, the same including'a ring-shaped base 68 and an upstanding attaching fiange 69; said annular ring 67 being supported for rotation with the -shaft 20, by means of

Vertical rods

70 and 71, which are-connected in the base 68 thereof, as illustrated in; Figure 3 of the drawings, and at their upper ends being connected in the portion 61 of the.

splin'ed collar 60, at opposite sides of Shaft |end 20. i

Thefiange 69 forms a track, upon which the i diametrically opposed rollers and 76 bear; the `rollers having suitable depending link ro'd connections V77 and 78 respectively, which at their lower ends are connected to a transverse member 80 which has Aa cable 81 connected at its upp-er end thereto, and depending aXially within the tower B, alongside of the shaft O, to any convenient Operating mechanism, which the opera ator may move in order to draw the Cable 81 downwardly, and thus tln'u the member 80; the

rods

77 and 78; ring 67; and

rods

70 and 71 move the collar 60 downwardly for closing the

half cylin'drical Sections

24 and 25 to the proper degree. i

From Figure 4 ofthe drawings it is apparent that the shaft C has a thru'st bearing on the top 12 of the tower B, illustrated at 85, and which may be of' any approved construction in order to 'sustain lthe weight and thrust of the wheel D.

From 'the foregoing description of this invention 'itis apparent that a `novel type of turbine windmill been provided, the wheel of whi'ch'is of novel character,which may be efidciently operated to close the same,

or eXtend. the same to various vdegrees, in order that the shaft may be operated at various speeds. The partsare simple in construction, and eflicie'n'tly arranged;

g Variousl changes ,inf'the' Shape, size, and

a'rrangement of parts may be'inarde tov the form ;of invention hei'ein shown and d'e-` scribed, without departing from the spirit of' thisinvention orfithe scope of the claims,
