YARN-CATCHER AND GUIDE-EYE FOR SPINNING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 270,179, dated January 2, 18 83. Application filed June29,18S2. (No model.)

To all whom it may concern Be it known that I. HORACE P. CHASE, of Lowell, countyot' Middlesex, State of Massa chusetts, have invented an Improvement in Yarn-Catcher and Guide-Eye for Spinning- Machiues, of which the following description, in connection with theaccompanying drawings, is a specification.

My invention has for its object to catch and holdthe yarn between the guide-eye and the traveler, and break it ofl' quickly whenever the yarn is sufiiciently slack to commence to kink and snarl to such degree asto be liable to do injury to the yarn running to adjacent spindles, the said yarn-catcher also acting to break off the yarn in case the yarn should break at the usual rollers above the guide-eye and comthence to drop down through the guide-eye.

In spinning-machines the weight of tho traveler and its friction on the ring-race while being drawn around the same by theyarn extended to and being wound on the bobbin must be suflicient 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. As the speed of modern spindles has been greatly increased, the weight of the travelers and the size of the wire from which they are made have been correspondingly decreased, and the strength and durability of the traveler havebeen. lessened, and its liability to be thrown off the ring has been increased. It a traveler be broken .or thrown from the ring, the yarn willkink and snarl; and so, also, should the yarn contain bunches or projectionssuch, for instance, as small pieces of cotton-leaf, or pieces of seed, or other foreignsubstance-the said bunch or projection, on arrivingat the travelerand 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 is thrown 0d the ring, theyarn must be caught quickly and-.be broken, orsnails 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 veryirequently happens that the badly kinked and snarled yarn,,after it has been broken off, will be thrown upon and be entangled with the yarns of adjacent bobbins, thus causing the breaking of a number of yarns along the side of the frame. To overcome these difliculties I have provided a yarncatcher which, should the yarn become sufficiently slack to form a kinkor snarl, will catch and immediately cause the yarn to be broken off or twisted apart at the catcher. I havelocat-ed this catcher at the front of the guideboard, and havemade it in one piece with theguide-eye, and the Wire from which the catcher and guide-eye is formed is so bent or shaped as to form what I shall denominate a slotted shank, common to both, whereby the com bined catcher and'guide-eye may be attached to the guide-board by meansot a singlescrew. Constructing the shank in this way and attaching it to the guide-board by an independent screw, which clamps it to the guide-board in an adjustable manner. enables the gnide-eyeto be more accurately adjusted on the guide-board and with relation to the top of the spindle than is possible with guide-eyes such as heretofore made, wherein the shanks are screw-threaded to be screwed into the edgenf the guide-board.

By careful observation in practical work I have discovered that a large proportion of the tors, who, in doffing the bobbin rapidly, turn I the guide-eyes accidentally as the guide-boards are quickly thrown up and down. The breakage of yarn also frequently results from a want of proper adjustment of the guide-eyes, they frequently being one turn of the screw too far in or too tar out,thus placing the guide-eye out of proper central position with relation to the spindle. In the form of my invention to be herein described the yarn-catcher, located below the guide eye, has an open space with flaring or curving sides, into which the yarn enters as it begins to bow or throw out below the guide-eye by reason of slack in the yarn, the

said space with flaring or curved sides ending witha slot or notch, into Which the yarn is drawn and by which it is caught and broken or twisted oft.

Figure 1 represents in front elevation a suffi cient portion of a ring-spinning machine to illustrate my invention; Fig. 2, a sectional detail on the dotted line as m, Fig. l; and Fig. 3, a detail in top view of my improved yarncatcher. I

The delivery-roll a, guideiboard 1), bar I), ring-rail b bolster-rail b spindle and bobbin b ring 0, and traveler c are and may be all as in common ring-spinning frames.

My improved yarn-catcher a is composed, as herein shown, ofa wire, d, bent to produce an open thread-catching eye, 2, (see Fig. 3,) having a narrow slot, notch, or space, 3. into which the yarn, once entering the eye 2 between the part 4 and inclined and curved surface 5 of the wire 01, will be drawn and be held securely until broken 0E.

My improved yarn-catcher and guide-eye f is'inade trom a single piece of wire d, bent as shown and described, parts of the wire being bent to form aslotted shank,f, to rest against theguide-board and be held firmly in adjusted position against possibility of turning by a set-screw, f

In operation, the yarn m, extended between the guide-eyef and traveler c, it even and free from bunches and imperfections, will occupy substantially the full-line position Fig; 1; but if a bunch or imperfection meets the traveler and slackens the, yarn sufificiently to cause kinks and snarls the slack yarn is thrown outward, so that it travels in a larger circle about the bobbin, as in dotted lines, Fig. 1, hich causes the said yarn to be thrown past the point 8 of the yarn-catcher and into the eve 2 and notch or space 3, where the said yarn will b caught and brokeu'ofi', after which the ya 11 )roken off at and between the catcher and bobbin will be wound upon the bobbins.

The two arms of the slotted shank resting flat on the guide-board may be adjusted into the exact position desired, and. be confined there by the single set-screw f.

I claim- I The guide-eye and yarn-catcher made in one piece, and having a slotted shank. f, by which to attach the same to the guide-board. substantially as and for the purpose set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
