THREAD-GUIDE FOR SPINNING-MACHINES.
SPECIFICATION forming part of Letters Patent No. 275,020, dated April 3, 1883,
(N model.)
injury to the yarn running to adjacentspindles,
the said yarn-catcher also acting to break oil the yarn in. case the yarn should break at the usual rollers above the guide-eye and cominence to drop down through the guide-eye.
In spinning-machines the weight of the traveler and its friction on the ring-race, while being drawn around the same by the yarn extended to and being wound on the bobbin, must be sufficient to enable the traveler to move at a speed a little less than that of the rotating spindle and bobbin to thus effect the winding of the yarn upon the bobbin. speed of modern spindles has been greatly increased, the weight of the travelers and the size of the wire from which they are made As the i has been correspondingly decreased, and the strength and durability of the traveler has been'lessened and its liability to be thrown oft the ring has been increased. If a traveler be broken or thrown from the ring, the yarn will kink and snarl; and so, also, should the yarn contain bunches or projections-such, for instance, as small pieces of cotton-leaf, or pieces of seed, or other foreign substance-the said hunch or projection, on arriving at the traveler and being unable to pass the same, will stop the winding of the yarn upon the bobbin, and thereafter the twisted yarn between the traveler and the guide-eye will become slack and kink, forming snarls of greater or less length. The lighter the traveler the easier for the yarn to kink on the occurrence of bunches or imperfections such as alluded to. When yarn containing a bunch or bunches too large to pass the traveler arrives at the traveler, or when a traveler is thrown off the ring, the yarn must be caught quickly and be broken or the snarls or kinks will be formed in it,
which will strike against, whip, and spoil the yarns extending to the bobbins each side of it, and it very frequently happens that the badly kinked and snarled yarn, after it has been broken ofl', will be thrown upon and be entangled with the yarns of adjacent bobbins, th us causing the breaking of a number of yarns along the side of thefraine. To overcome these difficulties I have provided a yarn-catcher which, should the yarn become suficiently slack to form a kink or snarl, will catch and immediately cause the yarn to be broken oft or twisted apart at the catcher. I have located this catcher at the front of the guideboard, in close proximity to the guide-eye.
This invention is an improvement on the threadcatcher described in United States Patent No. 41,582, February 9, 1864, to which reference may be had. In that patent the thread-catcher had a downwardly-extended arm provided at its lower end with a shoulder to prevent the yarn wound thereonv from passing oti' its lower end, and to hold the yarn until twisted or broken off.
In this my invention, in addition to the shoulder therein shown and described, I have provided the arm with a second shoulder or notch to break the yarn thrown about it and prevent the said yarn from working or sliding upward thereon, and from being drawn from the bobbin up through the guide-eye in case the said yarn becomes caught between the i usual rollers above the guide-eye.
Figure 1 represents in front elevation a sufficient portion of a ring-spinning frame or machine to illustrate my invention; Fig. 2, a partial section on the line 0000, Fig.1; Fig. 3, adetached top view of the combined yarncatcher and thread-guide, and Figs. 4, 5, and 6 views of a modified form of my invention.
The ring a, traveler a, ring-rail a", deliveryroll a hinged guide-board a spindle b, and bobbin 1) are and may be all as usual. In Figs. 1 to 3 I have herein shown the guide-eye f and yarn-catcher d as made from a single piece of wire bent to form a common slotted shank, f, to be attached to the'guideboard by a single serew,f ,.as described in my application No. 65,532, filed June29, 1882, to which reference may be had.
I shall herein denominate the downwardlyturned outer end of the yarn-catcher as the arm. This arm,besicles havingthe shoulder 2, common to the patent herein referred to, has a second shoulder or notch, 3, which serves to prevent the yarn rising upon said arm when the yarn, by reason of slack therein, is sufficiently bowed out, as on dotted lines, Fig. 1, to be thrown or wound about the said arm. \Vhen the yarn, for any reason, is about to become sufficiently slack to kink and snarl, as described, the slack yarn must be caught, broken, and wound up. In case the traveler flies off, the yarn is thrown about the arm; but with an arm having only the shoulder 2 at its lower end the yarn may be drawn upward over thearm and back through the guide-eye. This would happen should the slack in the yarn above the guide-eye be sufficient to permit the said yarn to be caught between the usual clearer and delivery rolls, and under such circumstances, were it not for the shoulder 8, the said rollers would act to draw and unwind from the bobbin the yarn already wound thereon. The addition of the shoulder 3 to the arm of the yarn-catcher obviates the difiiculty just alluded to.
In Figs. 4 to 6 l have shown the extra shoulder 3, added to the arm of a guide-eye, having the usual screw-threaded shank.
In the drawings I have shown but one roll above the guide-eye; but impractice the machine will have a set' of rolls such as commonly found in all ring-spinning frames.
I claim- As an improved article of manufacture, a yarn-catcher having an arm provided with two shoulders, 2 3, the former to prevent the yarn passing from the end of the arm and the latter to prevent the yarn passing upward above the top of the said arm, substantially as described.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
