BEER,
Application lilou July 25, 1916:
To all whom t may concern.:
Be it known that l', ,lossen T. lnoonnn, a citizen of the United States, Providence, in the county of Providence and State of Rhode island, have invented certain new and useful improvements in Wind-Up Devices for Sheeted Material, of which the followingis a full, clear, and exact description.
This invention relates to devices for winding up sheeted material and has for an cbject to rovide a device of this character which will. wind up sheeted rubberized matc'ial which has been challi'cd without su`njecting; the same to harmful pressure.
In the manufacture of rubberized fabric, after being'treated with rubber, the fabric is coated with chalk or an equ'valent, and is then wound up in a roll, the chalk serving to lice. the rubber lsurfaces of the convolutions from sticking together. lt is desirable that the fal'n'ic be smoothly and evenly wound up, and ordinarily to acconnjilish this, a constant tension is maintained on the fabric. This tension causes an increase in the pressure of the outer convolutions against the inner convolutions as the roll of fabric increases in diameter', and this is an objectionable feature, for when the pressure becomes too great, the chalk will be squeezed away in places, or at least harn'ifully thinned out, and let the rubber surfaces contact and adhere together.
To overcome this disadvantage, the pres a wind-up device in material is wound up by with a revolving' roller, roll upon the drive to supply suilicient which the roll of frictional Contact the weight of the fabric ing roller being utilized pressure to smooth out thi. fabric web dur ing the winding operation. As the fabric roll increases in diameter, provision is made for a corresponding.; movement of the axis of the roll away from the driving roller, so that the pressure of the outer convolutions against the inner convolutions will always remain substantially the same regardless of the diameter of the roll. Therefore at no time can a suiiciant degree of pressure be reached to squeeze out the chalk Afrom be tween the conv'olutions.
The invention can. be
from the following description readily understood. taken 1n conu Specification of Letters Patent.
residing at Serial No. 111,121.
nection with the accompanying drawing, in which- ,i
Figure l is a plan view "of the apparatus embodyingmy improvements.
Fig. 2 is an end elevation of the carts shown in Fig. l. L
Referring now to the drawing, in which like characters of reference designate similar parts, .l designates a frame upon which is supported a box ll for the reception of chalk or an equivalent. The bottom 'l2 of the box raised by screws 13 to maintain the chalk in contact with the rubberized surface of 'the fabric web il which passes over the open top ofthe boa. The web is fed to the box by a roller 'l5-which is power driven by a belt pulley lll or otherwise, there beine; a roller 'i7 vpivotcd on the end of the frame as shown4 at i8, to bend the fabric over the roller l5 so that the la ter can xget a food purchase on the web. rl`he chalked web drawn oil by a wind up device which is about to be described, surplus chalk beingy scraped off the traveling web by scrapers lQ-Lll of the usual and well known kind.
in carrying out the invention., l attach, supporting brackets 2l to the frame l0, there being bearings on the brackets to receive the shaft Q3 of a driving roller lll which is driven from a belt pulley or" otherwise. il pair of track rails are fined to the brackets 2l outside of the driving roller and are inclined upwardly from the driving; roller as shown. A pair of grooved wheels 27 ride on the 'traerand form journals for the en s `of a. shaft 28 upon which a take-up roller 29 for the fabric is fixed, there being ball lear'ngs (not shown) in a ball race 30, betweerl the shaft and wheels to permit the rolle1 to turn freely in the wheels. n
The inclination of the track is suilicient to maintain the take-up roller 29 in ric tional contact with the driving roller so that the rmer is driven by the latter. is soonV as convolution. of fabric is formed on the roller it will be driven by frictional engagement of the fabric with the oriving roller, the weight ofthe roll of fabric as the convolutions increase, serving to supply suilicient pressure to smoothly and evenly lay the fabric on the roll. s the roll of fabric increases in diameter the groei/ed. wheels sie lll@
27 are pushed outwardly and upwardly on the track, the inclination of which is such that the pressure of the outer convolution upon the inner convolution, caused by the weight of the fabric roll upon the driving roll, will remain substantially the same regardless of the diameter of the fabric roll.
In operation the fabric web is advanced progressively over the chalk box 1l and wound up on the rollerl 29. As the roll of fabric increases in diameter on the take-up roller, the roll will be rotated at a proportionate decrease in speed so that the ma; terial will be always rolled up'at a uniform speed regardless of the size of the roll.- Thus the tension ob the fabric can not increase as the roll increases in diameter. Since the roll is permitted to move outwardly away from the driving roller as the fabric convolutions accumulate, the pressure on the vmaterial from its own weight riding on the driving roller will be maintained substantially uniform so that at no time can a sufficient degree of pressure be reached to squeeze outl the cha-lk from between the convolutions of the fabric roll.
Having thus what I claim as new and by Letters Patent is:
In a machine of the character described a trough open at the top for containing powdered material, a source of rubber-coated fabric supply, a' reel for receiving the rubber coated fabric from the fabric supply source, means for guiding the fabric over the top of the trough from the supply source to the reel, winding means for feeding the fabric across the trough, means adapted to raise the powdered material in the trough to maintain it in contact with the rubbercoated surface of said material, and means for removing the surplus powdered.material from the said rubber-coated surface.
Signed at Providence, Rhode Island, this 15th day' of July, 1916.
