l ilheISchedule referred toin these LettersPatent and making part of the same.

I To `allavhom 'it may concern:

` Be it known lthat I, Caraninas'BnInGrnsv SMI'rI-, of

Grin, in the Icountyof Spauldingr and State of `C1veorgia,'have inventedia newfand valuable Improve- IImentinIAutomaticIEansyand I do hereby declare that the followingis" a full, clear,I and exact descripltionof fthe constructionand operationof the same,- reference beingIhadIto the annexed drawing making La part of this Fspecilication, and to the letters and. I 'tigures of reference markedfthereon) IFigure l of thefdrawinglisa side view of my fan,

` I with a portionof 4one side of the clockicase removed. I

Figure2 is a viewshowing my fandetached.' I

,y y ,I My invention has/relation to antomaticfaus, and I It consists in the novell construction I and arrange- I ment of devices inteudedIto serve Ias an eiicieut means for Vproducingan evencurrent-of air.

I Th'eeletter A of the drawing represents a frame,

designed to bebuilt of liglitmaterial,aud about seven' feet in height.` I I I II represents Ithe clock-work casehand is placed abontthe middlepti the Iframe A,`and`1 contains the clock-work `BI,I which `Iis` the motive power. This clock venixnggs. I II y y I i IITheclock-work can be run witheither a weight or` II spring; a spring,however, isusually employed.

.caselisrmly secured Ithe frame A bysuitable fast- I'lhrough asmall `slot'in the top of the clock-case `passes theverticallyevilor-ating` rodmO, which obtains I its vibrating mot-ioniioin1tlie' clock-work in the case I I B. It extends upwardwitlrin afew inches of the top n is secured by 'a pivot to Ithe lug on the s'leevea. ,j y

I I `Through this sleeve isI passed one endofthe rod b, I theother endof whichIis'pivoted to the vertical rod fofthean'.-

The end in'fthe "sleeveiis"secured-by' the thumbscrew c, whi h serves toreggulatel the vlength of the rod b.

the top of the frame A, and 'on the side facing I the ian, `is placed the'long arm D, which is lsecuredto 'lo keep 'it in position when in use thev brace d is the frameAby means of the hinge d', and isvjdesigned employed@ This is` `secured `to `therunder side ofthe arm Dlby "'a'smallliinget, The other .end of this brace'` is forked, to enable it to engage with the rail `c,wli-ichpasses around the frame Ajust above the clock-casel B. E represents the vertical-rod, to which the fan is Iattached. The upperend of this rod is secured to `the end of the long arm D bythe pivot b, in such a manner as to enable the rod E to swing .easily thereon back and. forth. The Irod E is cqnstructed'to slide easily in the rod I-E, to which the fan is secured, the height of this fau being regulated by the thumb-screw e. I

E represents the fan, which is attached to the roi cf by means of clasps f f.

Thisvfan is usually made Iof thin cloth or paper,

and can be renewed at will by opening the clasps j'. I

'lo make the attachment of the` rod e,"` to the rod Ef more rigid the bent arms or braces h It' are employed I f I the rods are made, is designedt be as light as possible to secure convenience in movingthe machine about the room. I

The rods C, E, and E are preferably made with a certain degree of elasticity, the reaction thus obtained being iavorabl'eto the production of currents of wind.

Sometimes, instead of pivoting the rods() and I1 immediately to the sleeve a and rod E, I prefer to 4provide at each end of the rod b vertical sleeves zz',

respectively pivoted to the rod b and to the sleeve a,

in such a manner that these sleeves z z shall be movable on the; rods G and The rod b therefore be- -comes adjustable, and can be raised or lowered to lengthen or shorten the tan-stroke, as may be desired.

Havingthus fully descl'ibedmy invehtion, l

I What I'claim as new, and desire to secure by Letters Patent, is I Y vThe fan-motor herein described, consistingr of the clock-work B', the vertically-vibrating rods C and E,

the adjustable horizontal connecting-rod b, and the adjustable fan-slide IE', when constructed and arranged `to operate' substantially as specied. I

In testimony that I claim the above I. have here;

unto subscribed my name in the presence of two witnesses. I
