Be it known ihel l, l'lsnm' O. BOWSMAN, a citizen of the United States, residing at Decaiur, in the county of Adams, in. the State of Indians, have invented certain new and useful Improvements in Driving Mechanism for Bolting-lriachincsr and I do hereby declere that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to molre and use the some, ref erence being had to (he occonipenying drewings, which form part of this specification.

My invention relates to improvements in drivin mechanism for bollin -machines.

g h The prime ob ect ok my present invention is to provide an improved driving incclnm ism for bolting-machines or" simple and economical construction, ellicient and reliable in op- 26 station, and provided with means for regu- .leting and changing; the limit of lmvcl of the sie ve-hox'in itsgyrstory movement without changing the speed of the driving-shalt.

{My lnventicn consists of it sieve-carrying Home or box suspended by flexible supports and adapted to have a tree lateral movemerit a vertical revolublc shaft carrying an unbalanced load, whereby oy the l'OizLllOIl of the shaft the sieve-ironic is given a gyrotory movement, and c Weighted m'nr odjustzibly mounted on the vertical shalt and edit ted to var or re olute the llllifill of the sieve-frame without chongin the succrl of the shaft.

Which- The principal norel feature of my invention resides "in the means for varying tho' gyro tion of the sieve-ironic withont changingthe speed of the driving-elicit.

Similar referenccnumerals indicate like ports throughout the several views, in

' cztted construction oi ils pivoted end.

The vertical drivixig-slnd't i has upon its r l l l l g l l I l l l l ripper end e fixed driving-pulley 2 and her 111g near its upper end it globuler ment 3 to forms bell-snd-socket hearing in the boxing 4, .whichis rigidl fixed onthc so porting beam or late 5,l i able vertical opening or the shaft 1 eving a suit r V The lower end of the vertical shaft hes a fixed or integral terminal ball. 6, having it suitable bsll-snd -soeket bcorin i in the boxmg 7 which is rigidly fixed on t is upper face of the sieve box or frsrne 8 of any proper construction. This sieve-frame 8 is securel y suspended from the supporting-beam ,5 by

any proper flexible supports 9, Whose oppc site ends are firmly secured to the piste {l and thebox 8 res ectivel The ion Clil 'ft the supports 9 are of course determined by,

the length of the vertical revcluble shaft."

in the vertically-slotted upper end of thei srin having a proximately right enguler ,1; branches 10 on 11 is arranged the collar 12,

pivotelly suspended therein by means of the; diametnc pins 13. This collar .12 is adapted to loosely receive the sheit l upon whicl the collar with its pivoted ti is edjustsbly mounted b a. set-screw lrl or other proper 8r;-

through the impulse of its centriingel force, which in turn is continuouslyimparted to the lower end of the shaft by means of its pivotel or bsll-end-socket connection therewith. It

is obvious that the effect of the centrifugal o force of the Weight 16 isto sense the lower end. of the-shalt i to describe e gyrstory movement, whoso'mnge or limit is determined by the adjustment of the collar 12 orthe sheft and the weights upon their respec- 10c tive arms 10 and 1], es follows: As the'ven ticel shaft 1 is pivotelly fulcrnmed near its ripper end on its bell-bearing 3, it is evident that the nearer the wei hted arms are adof the shaft the jnsted to the lower on greater will be the degree of centrifugal force exerted thereon, and consequently the greater will be the gyretory movement of the weight 16 and the smaller weight 15 their inner and outer adjustments, respectively.

lower end of the shaft. It is also evident that the centrifugal force and range of gyratory movement of the lower end of the shaft 1 1 is proportionately increased by the adjustment of the heavier weight 16 toward the outer end of its supporting-arm and at the same time adjusting the lesser weight 15 to ward the inner end of the arm. So it is obvious that the smallest range of vibratory movement can readily be secured by the adjustment of the collar 12 at its uppermost limit on the shaft 1, and by giving the larger As the gyratory movements of the sieve box or frame 8 will in use necessarily at all times coincide with the gyrations of the lower end of the shaft-1, it follows that the range of g-yratory movements of the sieve-box can readily and conveniently be-changed or regulated at pleasure by m invention without the speed of t eidriving-shaft. It -is also 0 vious that in the use of my invenmatic adjustment ofthe-gyratory movements of the sieve-box, which under all condition shaft, thereby preserving the balance between the weighted arms as the speed of the driving-ishaft changes. k aving thus described my invention and the mannerof operating the same, what I desire to secure by Letters ?Patent is l 1.
