' A pplica'tionfiiedFebruary 3,1923. Serial No. 616,828.
, This invention relatesto mechanisms of the character used in the textile industry to twist together several strands or ends of thread to form. a larger thread or cord of the required diameter. The invention isespecially concerned with twisting mechanisms of the cap type.
Ca twisters have been used' for a great inany years but their commercial use has been confinedto worsted thread or yarn.
Notwithstanding the fact that this is one of the oldest types of twisting mechanisms, it
. has never, sofar as I have been able to learn,
been considered feasible to twist cotton yarn or thread with such a mechanism, the ring type of twister being universally used for cotton yarn and thread. The chief disadvantage of the ringtype' of twister is that its speed is limited. About 2500 revolutions per minute is regarded as'the maximum speedv at which it is feasible to run a heavy duty ring twister on ordinary commercial work. I have discoverech however, that it is possible to runa heavy duty cap twister at very much higher speeds'on similarwork. For instance, a speed o-f'10,000 revolutions per minute on, cotton workcan readily be attained while producing entirely satisfactory results. 3
In attempting to run cap twisters of the usual constructions at higher speeds than about 2500 revolutions per minute, a number of difliculties have been encountered, especially in using yarn packages-of large diameters. Among thesedifiiculties may be men tioned particularly the excessive ballooning of the twisted strand, the fact that the increased lifting action exerted by the twisted strandon the cap raises the cap off thespindle, and especially the fact that excessive heat is developed both by the friction of the strand, on'the cap, and also by the friction between thespindle and the whirl and sleeve that rotate 'onthe spindle. To overcome these objections and to devise a thoroughly [satisfactory cap twisting mechanism ,that will operate at high speeds constitutes the chief object of the presen'tinvention.
The nature of the'.-inventio'n will be readily understood from the following description when. read in 7 connection j with the accompany ng dr ng an he novel f es In the drawings,
Figure 1 1s a perspective view showing one unit. of a cap I twisting machine con-.
structed in accordance with this invention; Fig. 2 is a vertical cross sectional view of the unit shown in Fig. 1;
Fig. Bis a vertical cross sectional View showing a slightly different construction of cap and a different means for controlling the ballooning; V v
. Fig. 4 is a horizontal cross sectional view of a balloon controlling tube embodying a feature of this'invention and showing it in its operative relationship to a cap;
Fig. 5 is a front elevation of the tube shown in Fig. 4; and r Fig.6 is a cross sectional view showing a modified construction of sleeve.
Referring to Fig. l, the spools or other will be particularly pointed out in the appended claims.
extending upwardly therefrom and. rigidly secured thereto. The whirl is moved up and down by the usual traverse rail 10, and it is guided during this rotative-movement by the stationary spindle 12 which is secured in the spindle rail 14:. A cap .15'is mounted on the upper end of the; spindle 12. I
,So far asthe general organlzation and arrangement of these parts is concerned. it is similar to that of the usual cap twisting machines. The strand S of thread is led from the thread guide 5 past the lower edge of the cap 15 to the spool 6, the rapid-rotation of this spool serving-both to twist the spool: The gradual raising and lowering movement of the spool imparted to it through the movement of the traverse bar 10 controls theplacing of the thread on the spool.
thread and alsoto wind it on the body of the As above stated, the liftingfaction exerted the strand on the loweredge; ofjthe' cap 16 and positively locks the capagainst accidental displacement during the operation of the machine. The direction of the screw thread is such that the rotation of the strand tendsto screw the cap oinmore tightly. \Vhenever it is desired to remove the cap, however, it simply necessaryto turnthe cap in the proper direction to cause the pin 17' to,. run upwardly in the: groove Tiev ap as be repla ed by a v r al of these movements. It 'is .conten p latecl that his P lem may be 01 d' n othe nes as. tor; instancefby providing the tip ot the I rating screw threads, or by providing a bayonet-joint cojn nection between them.
, The. excefisiveheating of the cap due tothe can -19 above mentioned has proved a serious obstacle to the operation of cap twistin machines at high speeds. I have found? 4 however, that by drilling several. holes '18 through the top of the cap, the air currents which are set up by the normal operation of the parts will cool'thecap very effectually; 'lhat is, air is forced through these apen tu'res 118, partly by the reciprocating movement of the spool 6 within the cap) and partly, also, by the rapid rotation of this spool: inside the cap. The natural tendency of the hot air. to rise withinthe cap and pass through the ventilating holes in'th'e top thereof may also account for so ne ofthe cooling action produced this: construction. This'avoids danger of the capb'ecoining oveitheated and it has thea'dvantage of providing an exceedingly econoinicahsolu tion for thisproblem.
.A sornewhatdifferent form of cap, is shown this cap being provided with a knob 21 which forms a convenient handle and faoilitates the ren ova l of the gap fro n thespindleand itsreplaceinent th r h I If; i
* I have also. found that the excessive heating" or sleeve, whirl, and spindle which have heen produced :io'r constructions when as asses are "ope-rated at lilgli Q 7 V r 1,611,166
being located at the upper end of the sleeve 9. These bushings may be shrunk into the sleeve and may, if desired, be made of brass, bronze or sonic other"material' which will reduce the friction created by their contact with the spindle. Since the bearing surface etween he spindleand the sl ve 1, confined to the two points where the bushings 19 and 20 bear on it, it will be lessthan would be the case if the entire sleeve were incontact with the spindle. A further advantage of this construction is that it facilitates oiling and prevents the sleeve from bindingon the spindle due to deflection of the spindle by the laterahpull 0n the band 8.
Another Tsolution 'for this problem is shown in Fig. 6 1-n wh1ch the sleeve 9 is contractedor swaged to-a'weduced diameter at the points 32*and' This=-arra ngeinent confines the bearing between the-sleeve and the "spindle to the "surfaces- 82- and 33, and thus reduces "t11e-ri-etion.-=-
Fee the purpose ot controlling the bal looning of the threadfl prefer to-substantially' enclose the cap in atube, 'T-he' ordinary balloon controlling or stabilizing ring will not answer the" purpose here for the reason that the balloon" will form-both above and below the ring. A'tube, however, such as that shown at 22, Figs-1, 2, gt and 5, does effectuallycontrol the" ballooning. This tube preferably'is held in an angular piece 23 Fi'gz' 1, which is supported by brackets chinetrance. V
