I" The Schedule referred to in `these Letters Patent and makiugpart ofthe same.

Be it known `that I, `EQNRY `R,ROBB'IIVI-s,-`of the y cityrandcounty of Baltimore, `and State'oflVIaryland,

`have.invented anew andfuset'ul Improveulentin Fly- .p lBrushes; and I dofherebydcclare that vthe `following fisafulhclear, and exactdescription of theconstru'c `tion and operation the same, reference being had l `specification,yinvwhich-- l Figure I sastre elevation, ma t i Aliigure2, a detached-elevation of-the supplementlary winding-apparatus" i. `This iuventionjfrelates `toa portable apparatus, in

`which a brush `orA fan isanade-to oscillate by means of `machinery,ifor the purposedf driving flies from a ta .bleor bed, and creating at the same time a breeze.

The inventionconsists-f l First, in appending to the drum Aof the clock-Work C that l.operates the brush, `both a coiled spring and a cord and weight,v` for the purpose` of accelerating, byA .l `the latter, the mot-ion `communicated to the drum by the former, Wheneverfit maybeldesired. i

` Second,.iu'combiningg with the motor-mechanism, a

Ubrake, having arubber orleather cushion.-

l Third, in combiuing'with `aratc1`1et,ion thel stem of `the1.\vi ndix 1gdrum oi" the; motor-mechanism, a pawl,

l having a slot in,lit`s "upperg end, throughwhich a setsereniT passes, connecting thepawl with the. standard, by means of` which slot and, lscrew'the paWl` may be drawn over `the ratchet,` rotating it, and thus wind up the `mechanism, the paWl being retracted after each drawino' down b lmeans'of as irais -rin theratchett y l Q P g... pa\vl,fand sp1-111g` formmgla supplementary Awlndlng- `.A .is the" standard of t'ljleiappa'ratus, set in a footlic frame,` B, which contains the`motor-mechanism.`

The `main drum a 'of the latteris primarily-,actuated in the usual mannerby `a springe', coiled around the `shattofthe drum.` y y. 1 i Then it may be desired to impart to the brush or,A

fan `a higher degree of speed than is'due to the spring alonc,-a cord, b, is tov be "attacl1ed;to'tl1e surface oi' the drum, havinga weight, b', at one end of it, which,

`by its gravity, accomplishes the end in view."

l To check the mechanisml at any time, I employ a brake, c, having, .for the part that comesin contact 14 with the Wheel, a cushion, c', of rubber or leather,

cushion relieves the metalpart-s from friction, and may l be renewed when Worn. f. y l

The shaft of the lwinding-drum d projects through one side of the` metallic frame B, and s"squared oli' in `the common form, in. order to give the key a hold.

A supplementary Winding-apparatus, to'befused 4when the key islost, onwhen'the frame B is too high to be oonvenientlyrreached, isrmade up of the ratchet il" on the shaft d', the pawl e havingteeth that engage with the teeth of the ratchet, a slot,"A e,'ii1` `its upper end, through which a set-screw passes into the side of the frame B, and a curved handle, e, to an eye in the lowerend of which a vcord is attached for pulling the pawl down, which latter motion rotates the shaft d and the Winding-drum. i l

After each movement o' the pawl downward, it is retracted by the spiral spring lh, and drawn into posi',-

tion to .be operated upon at the next pullL Having thus described my' invention,

p Vhat I claim as new, and desire to secure by Let- 1 1. The combinatiolnavith themain drum a, of Vthe coiled spring a and the cord and Weight b b', arranged and operating as set-forth.

2.` The winding-mechanism, consisting of the slottedi pawl c, ratcheta", and spiral spring h, all arranged to operate in the manner explained.

The above specification f my invention signedby Vme, this 23d day of August, 1869.
