YARN-CONE-HOLDING ATTACHMENT FOB, KNITTING MACHINES. a

Application filed July 26, 1927. Serial'No. 208,634.

This invention relates to attachments for knitting machines, and particularly to means for supporting a. cone of yarn.

, Cones of yarn are Ordinarily supported with the apex of the cone upward and when knitting very fine yarns the yarn is liable to pull and drag across the face of the cone, causing too much tension on the yarn and in some. instances breaking the yarn.

The general object of the present invention is to provide means whereby a cone may be supported in an inverted position, or in other words upside down.

A further object is to provide a device of this character embodying a conical body, with means for supporting it in an inverted position, and provide resilient latches mounted upon this body and spring-project ed into engagement with the cone of yarn so as to hold the cone inverted whereby to facilitate the yarn pulling and running off the cone.

Our invention is illustrated in the accord panying drawing, wherein Figure 1 is an elevation of our cone holding attachment;

Figure 2 is a vertical sectional view'of the attachment engaging the yarn cone;

Fig. 3 is an elevation of the attachment separated from the cone;

Referring to this drawing, it will be seen that our invention embodies a conical body 10 which may be made of wood or any other suitable material and which has inserted in a it the shank 11, which shank extends axially upward through the body 10 and then is angularly bent, as at 12, and screw-threaded for the reception of the nuts 13. A bracket 14: has apertures through which the shank 11 passes and this bracket is engaged on each side by the nuts 13 so as to hold this supporting rod or shank in its adjusted po sition upon the bracket.

The body 10 at diametrically opposite points is illustrated as being provided with the inwardly extending slots 15, these slots being relatively deep toward the edge end of the conical body 10 and being relatively shallow at their opposite ends. The inner ends of these slots are rounded, as at 16. Attached at one end in these slots or grooves are the spring latches 17. Each slot is at tached by a screw 18 at its lower end in the corresponding groove and the upper end of each latch is formed with a re-curved handle portion 19. The curved end 16 of the slot accommodates the beginning of this handle portion. Each of these latches is resilient so that it is normally held. in anoutwardly projected position and each latch is formed with a plurality of prongs 20.

A yarn cone holding device of this character is. adapted to have the cone 21 with the yarn 22 thereon inserted over the body when thelatches are retracted. The latches will then spring outward and the prongs 20 will engage the paper cone 21 and hold it firmly in inverted position without any danger of the paper cone coming off. lVhen the yarn has been used up, the latches are retracted ,so as to permit the pasteboard or paper cone 21 to be, removed and a new cone put in place. This attachment has been found to be particularly efiective where very. fine yarns are to be used, as supporting the yarn cone in an inverted position, that is inverted with relation to the ordinary way of supporting a yarn cone, very greatly facilitates the pulling off of the yarn from the cone. The yarn willpull off very easily and there will be no drag whatsoever, thus obviating very materially trouble knitters are having with very fine yarns and with cones disposed with the small end of the cone upward.

While we have illustrated a particular embodiment of this invention, it is obvious that it may be modified in many ways without departing from the spirit of the invention and that it may be embodied in other forms than the form shown and still be within the scope of the claims as hereinafter presented.

We claim l 1. A yarn cone holding attachment for knitting machines comprising a downwardly ,tapering body, a shank extending upward from the body and adapted to be engaged with a bracket, and resiliently pro ected latches mounted upon the body, the body having recesses into which the latches may be manually withdrawn, the latches having outwardly projecting prongs, the latches extending beyond the larger end of the body and having inwardly curved portions providing means whereby the latches may be retracted against their resilience.

2. A yarn cone holding attachment for knitting machines comprising'a downwardly tapering body, a shank extending therefrom whereby the body may be supported in an inverted position with the tapering end downward, the body being formed with radially extending grooves opening at the top of the body and extending downwardly near- 1y tapering body a plurality of downward 1y to the tapering end of the body and rely convergent, resilientliitehes mounted upon silient, outwardly projected latch members saidbody, the latches projecting beyond said p ii said r eve en h ng their be y n ;ea ilet hlw es i wers lyw lower ends attached to the body, the upper to provide a finger hold whereby the latches ends of therinembersnhavinginwardly re- .maylhe retractedstowandithembody against curved handles whereby the latch members their resilience, the latches being provided may be retracted, the latch members being with outwardly projecting prongs. 20
