TENSIONING DEVICE FOR SPOOLING MACHINES.
Application filed March 4, 1922. Serial No. 541,093.
To all w hom it may concern:
Be it known that I, CINoINA'r s H. LAND, a citizen of the United States, residing at Lindale, in the county of Floyd and State of Georgia, have invented certain new and useful Improvements in Tensioning Devices for Spooling Machines, of which the following is a specification, reference being had to the accompanying drawings.
This invention relates to thread or yarn tensioners, and particularly to the tens1oning devices of spooling machines for spooling cotton.
One of the objects of this inventlon 1s to provide a very simple tensioning deylce which may be applied to spoollng machlnes without any. change in the construction of the machine and which will secure a uniform tension on the yarn or thread according to the size of the thread. D
A further object is to provide a dev ce of this character which. is adapted to place a uniform tension on all counts or sizes of thread and which does not have to be changed when passing from fine to coarse thread.
A still further object is to provide a tensioning device of this character which can be used in spooling yarn from a filling wound bobbin, thus enabling an increase of from to in the speed of the spooler and an increase in the speed of spinning from 10% to 20%.
Another object is to provide a device of this character adapted to be used in connection with a warp having a filling wind and which will save 90% of thread waste caused by tangled or soiled bobbins.-
Other objects will appear in the course of the following description.
My invention is illustrated in the accompanying drawings, wherein Figure 1 is a side elevation of a bobbin holder and tensioning device constructed in accordance with my invention;
Figure 2 is a front elevation of the structure shown in Figure 1;
Figure 3 is an enlarged vertical sectional view through the tensioning device.
Referring to these drawings, 10 designates the main bobbin and head stand which is of usual construction and fastens on the usual supporting rod 11 by means of the set screw 12. The upper portion 13 of this head stand is pivoted to the lower portion by means of the bolt 14 so that, the upper portion may be adjusted. The lower portion of the head stand is formed with the usual bracket 15 having a stud for supporting the bobbin 16, from which the thread is wound. I have not illustrated the spool upon which the thread is wound, the yarn guides, or any of the other associated mechanism, for these parts are well known and need no illustration.
My invention consists in placing a tensioning device of peculiar construction upon the extremity of the head stand. The section 13 of the head stand is formed with an upwardly extending lug 17 which is laterally extended, as at 18, and formed with a recess 19 on its under face. Disposed immediately below the lug 18 and bolted or otherwise attached to the section 13 near its extremity is a conical member 20 which is held in place and from rotation by a bolt 21, this conical member 20 expanding outward, that is away from the section 13. The conical member 20 has immediately beneath the recess 19 a concave neck 22 which merges into the outwardly flaring surface 23 of the conical member 20, and disposed to rest upon this concave neck and rotate thereon is a steel ball 24, the upper portion of which extends into the recess 19 and is held by the walls of this recess from getting out of place, while at the same time it is perfectly free to rotate. The member 20 is preferably made of porcelain, though I do not wish to be limited to this material, while the ball 24- is preferably made of steel.
The yarn a from the bobbin is passed over the concave neck 22 of member 20 and is carried around the neck one time and then passes to the spool on which the yarn or thread is being wound and through a suitable thread guide (not illustrated). Inasmuch as the member 20 flares outward, the yarn cannot get off the member 20 and the yarn always is disposed in the neck 22, the ball resting upon the' yarn. An arcuate guard 25 formed of wire or like material is attached at one end to the extremity of the section 13 and extends downward and rearward to a point to one side of the section 13 and beyond the tension roller 20, as illustrated in Figure 1, this guard preventing any ballooning of the thread at the point where the thread passes from the bobbin to the tensioning device. The ball 24: makes the thread bind close to the stud or roller 20 and causes a uniform tension on he thread according to the size of the thread, for the reason that the larger the diameter of the thread or yarn, the greater the frictional contact of this thread or yarn with the stud and the greater tension, therefore, will be placed upon the thread or yarn, while the less the diameter of the thread or yarn, the less the tension on the thread. Thus it will be obvious that no regulation of the tension is necessary and that thus this device gives a uniform tension on all cdunts of thread.
It is not necessary with this, device to change the ball or stud 20 when changing from fine to coarse thread. By using this device, it is possible to spool or cone yarn from a filling Wound bobbin, thus enabling the speed of the spool to be increased from 20% to 30% and perinittiiig the spinning to be increased in speed from 10% to 20%, while'the thread or 'yarn Will run as ivellor even better in inostca'ses than when a low speed is used.
As will be noted fIOHl the drawing, the ball 24: has a diameter somewhat largerthan .the diameter of the smallest portion of the neck 22 where the loop of thread passes are'und the neck. The tension in iny device is secured by carrying the yarn or thii'eadaround the neekin the forinojf a single loop. The ball is not used essentially as a means for securing tGIgSiOn but as'a means for pre venting the loop from at any time enlarging on the thread, this ball resting upon the thread or yarn at the point wherethe loop of yarn around the neck 22 is 'cmiipl'eted so that the ball bearson the yarn at the beginning of the loopand at'the end of the loop and thus holds the loop from opening up or slackening intermittently. I have found by many experiments and service tests that because of thefact thatthe yarn is carried in a loop around the neck of the stud that the neck should be relatively small in comparison with the size of the ball which rests upon the thread, and that this ball will only be large enough to prevent any slackening of the loop.
It is also to be noted that there is no obstruction which would tend to prevent the ready looping of the thread upon the stud. Thestud is made of porcelain fer the reason that the porcelain has a highly vitreous surfaceover' which the thread passes with a substantially even friction, and I have found that a porcelain stud will wear i'o'ria very long time and will not, oi co irse, tarnish,
corrode, rust or be ot-herwise afl'eeted, whereasif the stud 20 were of metal, even thoiigh spooling mechanisms, but in all devices known to inethe weight has to be'changed or a spring tension is used which must be adjusted, whereas with this device nothing is changed except the producing machines. The spinning frames are sp'eeded up 10% t0 2O% and the spo'olers 20% to 30%, and the tension device will give the proper tension on all counts of thread. In installing, it is only necessary to take the old style b0bhin holders off and the tension device fastens on the same rod as used for the holders.
lVith my device there are no changes necessary to 'be made for the diflie'ren't numhers of yarn and there are no springs to. accumulate lint and cause had work. other yarn tensioning devices known to me, 'it is necessary to change the balls, rollers,
springs or weight in order to give the proper tension on the yarn for different numbers With of yarn and to tighten or loosen the spring.
This is unnecessary with my device.
Vhile I have illustrated a particular form of stand and bobbin holder, it will be obvious that these may be varied in many ways in order to meet the requirements of different lengths'of bobbins;
I claim':
A tensioning device of the character described comprising a support including a studinounted upon the support and having a relatively small, transversely concave neck cylindrical in'c'r'os's section, the stud beyond said neck expanding outward, the stud being composed of vitreous material having a highly polished'outei' surface, a member extending'oi 'e'r the neck'of the stud and having a recess in thegiace coiitrontingi the neck,
and a ball disposed in said 'recessantl'restihg upon the menus ball having a diameter not less than the diameter of "the neck at its smallest 'part.
In testimony whereof I hereunto aliix my signature;
CINCINATUS ii. LAND.
