CHATTANOOGA, TEITNESSEE, A GOBEORA- TION OF TENNESSEE CONE HOLDER Application filed December 3, 1927.

this invention protuberances are formed on the surface of the cone holder which serve to prevent the yarn being drawn under the cone. Throughout the specification and claims it should be understood that where the word cone is used it includes bottle bobbin, cop or any other form of wound yarn. The invention will be shown and described in use on a knitting machine.

In the drawings;

Fig. 1 is an elevation of a cone of yarn mounted on the novel form of holder;

Fig. 2 is a plan view of the flange of the new holder, showing another arrangement of buttons; while Fig. 3 is an elevation of another form of holder in which the flange is formed integrally with the bracket supporting the holder.

During knitting on a circular knitting machine the yarn is customarily drawn off the cone of yarn upwardly, the yarn unwinding round the stationary cone so rapidly that it tends to balloon outwardly. If for any reason the machine should cease to draw yarn the surplus drawn off the cone tends to get under the edge of the cone. When the machine next jerks the yarn taut the slack catches on or under that part of the yarn still remaining on the cone causing great tension on the yarn and frequently breaking the yarn.

Referring now to Figs. 1 and 2 of the drawings, the usual bracket 5 with its fiattened end 6 supports a novel flat disc or flange 7 made of metal, rubber, composition, ceramic material or any desired substance. The upper surface of this flange is irregular, these irregularities taking the form of a plurality of protuberances or buttons 8 in the example shown in the drawings. These Serial No. 23?,504.

buttons may be of any desired size or shape but it has been found that rounded hemispheres about one quarter of an inch in height serve very well. The number of buttons and their arrangement can be varied as desired or according to the size of the cone and the kind of yarn being used. In Fig. 2 of the drawings the buttons have been shown arranged in three concentric circles with one or two of the circles outside the edge of the cone. The buttons can be spread around more thickly, if desired, and in any case it is preferable to place them with sufficient frequency near the maximum diame ter of the cone to catch the slack yarn as it drops off a new cone and hold it from being dragged under the bottom edge of the cone. Some of the buttons should be within the area covered by the maximum size of the cone, in order to catch the yarn when the cone is partly unwound.

There is the usual cone-holding pin 9 mounted in the bracket 5 and projecting up through the flange 7. The cone 10 with its cardboard core 11 is on this pin. It will be observed that in the cross wound cone used on knitting machinery the cardboard core projects below the yarn, thus leaving a space under the yarn above the flange.

The construction shown in Fig. 3 is substantially the same as that in Figs. 1 and 2 except that a flange 12 takes the place of both the flange 7 and the flattened end 6 of the bracket.

In operating the knitting machine if slack is formed for any reason or the machine is stopped and started again, the yarn y which has been ballooning out as shown in Fig. 1 will drop down to the position shown by the dotted line and frequently form so much slack that it tends to draw itself under the bottom of the cone. According to the present invention this slack comes in contact with the buttons 8 and is held out from under the cone as shown in Figs. 1 and 2. When the machine takes up the slack these buttons in no way interfere with the yarn resuming its active position. It will be ob vious that these buttons not only keep the yarn from harmful contact with the cone but also keep it from becoming entangled with itself.

I. claim:

1. A cone holder with a flange below the cone, said flange having a plurality of buttons on its upper surface adapted to keep yarn from moving under the cone.

2. A cone holder with a flange below the cone, said flange having a plurality of buttons on its upper surface, some of said buttons being located at least as far from the center of theflange as the maximum size of the cone, for the purpose described.

3. A cone holder having a pin for the cone, a flange around the lower end of the pin and buttons on the upper surface of the flange, at least some of said buttons being located within the maximum size of the cone, for'the purpose described.

In testimony whereof I have signed my name to this specification.

EDWARD ALEXANDER MAGILL.
