at whom it may" concerni- Be itknown that I, GILBERT E. Jonas, a

citizen s-f the United'States, residing at New 'York, in-the county and State of New York,

have invented new and iuset'ul-I-mprovements iniMachinesforWinding'up'Paper,-of which 7 t f owin is a specification. y

, This'invention .consists -in a winding-ma- 1 chine having a delivery-rolha power-roll, and

aw-inding-up' roll which ;is held in arms, guides, or ways which are provided with frictional boxes or slides, a'nd'which is. thrown towardthepower-roll bygrayity.

, In the accompanying draw ngs, Figure 1 is a 'topview" of a machine arranged to wind dampened or dry-paper. Fig. 2-is aside yiew' ntjflie' same. Fig. 3 is an end-view of the same 'EiE-, 4 is -a topviewtof a modification.

- Fig hisa side view of the same.

Winding-machines arecOnstructed either fordry 'or dampened paper or for other fabrics, whichmachine's usually consist of a roll from-which the fabric is beingunwound, and

'oiaroll upon'which it is being wound, the

latter resting and'pressing upon a power-roll or driving-roll made of iron or other material, and from the frictional contact with-which the roll being formed is driven or revolved. By this arrangement the speed of the fabric between the delivery-roll and the windingup=roll is always the same.

it has heretofore been the practice to'create thenecessary amount of pressure between the 'roll'being formed and the power-roll by the weight of the winding-up roll itself, as the :same bears upon the power-roll, combined I continually jump backward and forward to and from the power-roll, and theroll of fabric when formed will'never be perfectly true and tion to gravity, to resist the backward or upward movement of the roll being formed from the power-roll,the former, even when revolving -at a circumferential speed of thirty milesan hour, will be perfectly true and even, and no perceptible jumping will take place.

In Figs. 1, 2, and 3 the letter A designates the roll froi'n which'the dry paperis taken or unwound. ,The paper then passes over a table or support, and water is thrown upon it' .in the formofafinespray: The paper thus vdampened is woundinto aroll, (shown at B,)

which roll rests upon and .isitnrned by a power-roll, G, the latter being revolved-by a beltor in some other suitablemanner. The roll B is held by arms D D, which areinclined towards the power-roll C, and which at their lower ends are provided with pins ff, turning in suitable boxes,thusallowing the spindle of the roll B to move away'froni the roll 0 as the roll B is enlarged by the addition of the paper.. The bearings orjonrnal-boxes h h hh,

inwhich the pins ffot' the arms D rest, I

make with acap and bolt-sin each box, so that the power necessary to elevate the arms can be adjusted by tightening or loosening the bolts. Thus, when the machine is in operation the pressure between the rolls B and C is increased beyond that due to the weight of the winding-up roll B, thisroll will not percep-'- tibly jump'away from the roll 0, and the completed roll of paper will be true and even. A mere increase of the pressure between the ,rolls B and C by weights does not produce the desired effect.

In Figs. 4 and the letter A designates the the roll from which the fabric is taken. 0 is the power-roll, and Bis the winding-up roll. X X are inclined guides which carry boxes or journalsa of. the spindle of the roll B, and these boxes are constructed so as t0 clamp closely the guides X X by set-screws, as shown, on the sides of the-boxes a. The slidesX X areinclined, so that the roll B is held in contact with the power-roll by its own gravity, and when boxes a have been clamped on the guides and the machine is set in operation the pressure between the rolls -B and 0 will be auginentedby the power required to overcome the friction between the boxes and the guides. 4

, With my invention using friction in addition tothe gravity of the roll,'movement of said roll away from the pressure-roll will be resisted, while its movement toward thepressis prevented, and said roll will be perfectly chine without-friction upon the journals or' winding-up roll held in arms, guides, 1

. named features'has trated in a printed even when finished, while with the weights and no friction ot'he'r than necessarily existing in the moving parts, the roll B will thump againstffthe power-roll, and will not, when finished, be perfectly'trne and even. fl arious other forms and designs of machine may be adopted. The roll being formed may be directly over the power-roll and. .rise vertically from it. With this design the resistance oifered by the friction to the paper-rolls upward movement, in addition to the weight of the paper-roll itself, will cause said roll to be made evenly and truly; and will prevent all jumping. I I

I find out .the 'proper amount of friction necessary in any winder by starting the maslides, and I gradually increase the friction" f till all thumping and unevenness are obviated and the machine operates steadily and smooth- 1y, producing perfect-1y even rolls of paper. I do not claim, broadly, as myinvention a winding-machine having a-delivery-roll, a or ways which are provided'with friction-boxes, combined with. a power-roll, since I have recently found that a machine containing the above- .been described and illuspublication priorto my-invention thereofi- In this machine the winding-up roll is hung the power-roll by gravity.

in arms which swing on a vertical axis-,so that the gravity of said roll does not hold the same in contact withthe power-roll. A mar chine of that kind may be used with advan tagefor winding up cloth or other material strong enough to hold the winding-up roll in contact with the power-roll by its own tension; but my experiment-s show'that such a machine can not-be used for winding up paper, since the paper is not strong enough to prevent/the winding-up roll from being thrown out of con tact with the paper-roll, and when an attemptis made to wind up paper on a machine of this kind the paper will tear after a few revo- '45 v lutions of the roll.

What I claim as new, and desire to secure by Letters Patent, is

In a winding-machine, the combination, with the delivering-roll and the power-roll, of a winding-up roll which is v heldinarms,guidcs, or ways which are provided with'frictio'nal boxes or slides, and which is thrown toward In testimony whereof I have hereunto set my hand and seal in the presence of two subscribing witnesses.
