JOSEPH SHAW GAUNT AND HARRY DYSGN, OF MANCHESTER, ENGLAND.

YARN-GUIDE EYE.

Specification of Letters Patent.

Application filed June 18, 1917. Serial No. 175,260.

To (ZZZ whom it may concern.

Be it known that we, JOSEPH SHAW GAUNT and HARRY DYsoX, of Manchester, in the county of Lancaster, England, have invented certain new and useful Improvements in Tarn-Guide Eyes, of which the following is a specification.

The object of the invention is to simplify the method of carrying and retaining the yarn guide eye upon the cup or flier so that it may be easily and quickly removed when worn by the friction of the yarn as it passes through the eye and a new eye quickly and firmly substituted.

The yarn guide may include a yarn-re ceiving eye, a shank, and a shank base formed to slide in a suitable groove formed in the top face, or other convenient position in the flier. The groove is made of sufficient depth to permit the shank base to be completely embedded therein to a suflicient depth to allow a bridge to be engaged with the flier above the shank base, so that to locate the guide in position it may be necessary to slide the base below the bric ge.

The guide is so made that the base enters below the bridge in a direction opposite to the direction of revolution. These de tails will now be more precisely described with reference to the accompanying sheet of drawings in which Figure l is a plan of the upper face of the cup or flier.

Fig. 2 is an elevation partly in section.

Fig. 3 is a view similar to a portion of Fig. 2 showing a special form of yarn guide with a two-part base and stem.

An annular groove A is formed in the upper or other surface of the cup or flier B and of sufficient depth to allow the introduction of a bridge extending across the groove above its bottom, said bridge being preferably composed of two or more pins C, D, adapted to cooperate with the yarn guide and groove; Said guide as shown bv ,Fig. 2 includes an e e E a shank E and a shank base E formed to enter the groove A, the said base being adapted to be inserted by sliding it in the groove below the bridge. The forward rotation of the cup or flier maintains the bridge portion formed by the pin G in contact with the shank E and prevents the base from sliding out from below the bridge and always tends to retain it in the position shown and prevent it from flying out, this tendency being aided 'by the drag of the yarn, Any suitable form of eye may be employed, either integral with or firmly attached to a suitable shank. For soft yarn an eye E having a double hook or loop formation such as shown in Fig. 3 may be used, so that the yarn may be given one or more turns around the eye in order to take up the strain on the yarn from between the front roller and the cup or flier and transfer the strain to the winding point where it is fully twisted and more able to withstand the strain of winding and overcome the friction of the spindle which with its bobbin or the like is rotated by the pull of the yarn when in operation.

In order to better support the eye E in position, the shank may be composed of two members E E and the shank base Patented Feb. 19, 1918.

of two members E, E projecting in oppo- V 7 site directions from the shank, one of the base members being shorter than the other. The longer base member is first inserted below the pin D and pushed under the same until the outer end of the shorter member passes the other pin C, when the shorter member will enter the groove between the pins. The shorter member may now be pushed under the pin 0 until arrested by contact of the shank with said pin, which will happen before the outer end of the longer member passes from under the pin D.

Claims:

1. A rotary cup or flier having a groove, a bridge in said groove, and a removable yarn guide including an eye, a shank and a shank base, slidable in the groove, the shank and base being formed to cooperate with said groove and bridge in retaining the guide in place on the flier, the shank being arranged to abut against said bridge to limit the sliding movement in one direction.

2. A rotary cup or flier having a groove, spaced apart pins bridging the groove, and a removable yarn guide including an eye, a shank and a shank base, said base being slidable in the groove under said pins, and said shank being arranged to abut against one of said pins to limit the sliding movement in. one direction.

3. A rotary cup Or flier having a groove, spaced apartpins bridging the groove, and a removable yarn guide including an eye, a shank and a shank base, said base being composed of longer and shorter members projecting in opposite directions from the limit the sliding movement in one direcshank and slidable in the groove, said pins tion.
