' UNITED STATES PATENT OFFICE :Bmmmm arnc'ron, or new YORK, n. Y., ASSIGNOR T0 enorrmz. sroar Arum co., me, or NEW YORK, 1v. Y., a conroRArIoN on NEW YORK YARN CARRIER FOR KNITTING MACHINES Application filed August 22, 1930. Serial No. 477,018.
This invention relates to yarn carriers for knitting machines and more particularly to yarn carriers adapted for use in the production of plated fabric.
An object of the invention is to prov1de a device of the character described whlch' is simple and sturdy in construction, which ma be manufactured economically, which is e fective under a variety of operating conditions, and which will efficiently accomphsh the purposes for which it is intended.
A further object is to provide improved means for reversing the position of the yarns in the production of plated fabric on a flat knitting machine. 0
More specifically, it is an object of the 1nvention to provide means to asslst the movement of one yarn about another yarn when the direction of the movement of the yarn carriers is reversed in the production of plated fabric on a fiat knitting machine.
Other objects of the invention will in part be obvious and will in part appear hereinafter.
The invention accordingly comprises the features of construction, combinations of elements, and arrangement of parts, which will be exemplified in the constructions hereinafter set forth and the scope of the apphcation of which will be indicated in the claims.
For a fuller understanding of the nature and objects of the invention, reference should be had to the following detailed description taken in connection with the accompanying drawing, in which:
Figure 1 is a front view of a portion of aflat knitting machine showing a yarn carrier embodying the invention as it appears when moving in one direction;
Fig. 2 is a similar view showing the yarn carrier as it appears when moving in the op osite direction;
ig. 3 is a top view of the exemplified yarn carrier;
Fig; 4 is a side view thereof, showing certain associated elements;
Fi 5 is a detail side view illustrating a modi ed form of construction;
Fig. 6 is a detail bottom view of this conoperating cams is reversed at the end of each course, the relative position of yarns must be correspondingly reversed, and to permit such reversal, there 1s commonly utilized a member such as shown at 10 which provides a small opening for one of the yarns and provides for the other of the yarns a generally arcuate opening terminating at either side of the small opening, so that upon the reversal of the movement of the guiding member, the yarn extending through the arcuate opening will, due to its lag, pass rearwardly along the entire length of the arcuate opening, so as to occupy a position at the rear of the first yarn. Considerable difficulty has been experienced in the failure of yarn to move with speed and certainty along the course provided by the arcuate opening, and this is particularly the case in the use of relatively thick yarns of irregular width, for example, knotted yarns, such as boucl yarn and rattin yarn. This disadvantage is enhanced by the knitting and structural requirements involved in most knitting methods and machines which limit the size and shape of the slot.
With these and other considerations in View, the present invention contemplates the provision of a supplemental guiding member which will cause the yarn to move from one end of the arcuate opening to the other with ease and certainty, and further contemplates the provision of positive means for reversing the position of the yarns. The exemplified yarn carrier comprises a guiding member 10 formed with a small opening 11 adapted to guide a yarn 12 and with an arcuate opening 13 adapted to guide a yarn 14. The member 10 is supported on a suitable frame piece 15 which in the present instance is formed with a supplemental guide opening 16 for the yarn 12. In accordance with the invention, there is pivotally mounted, as by means of a screw 17 at a point in line with and in front of the opening 16, a swinging member 18 formed at its outer end with an openin 19 for the yarn 14, the distance between he openings 16 and 19 when the member 18 extends to one side, being considerably greater than the distance between the opening 11 and either end of the slot 13. The yarn 12 may extend over a suitable sliding pulley 20 to a spool 21 and the yarn 14 may extend over a suitable sliding pulley 22 to a spool 23.
It will accordingly be seen that when the direction of movement of the yarn carrier is reversed, the lag of the yarn 14 will cause the pivoted member 18 to swing to the rear and the tension on the yarn 14 resulting from the movement of the pivoted member, will assure a speedy and direct movement of the yarn 14 from one end to the other of the slot 13; the reversal of this action resulting when the yarn carrier changes its direction of movement at the other end of the machine. The are through which the opening 19 swings is sufiicient to cause an effective pull which will overcome any resistance due to friction of the yarn against the walls of the slot 13, so that the yarn 14 when it is received by the needles will always be at the rear of the yarn 12 and that the danger of the yarn 14 eing frictionally held ahead of the yarn 12 with resulting imperfections in knitting, is effectively eliminated.
In certain instances, as when the entering yarn exerts a pull inwardly, suitable means may be provided to limit the movement of the free ends of the pivoted member in a direction toward a member such as 10. Such a result may be obtained, for example, by so constructing the pivoted member that the distance from the axis of the pivot pin to the side edges of the pivoted member is greater than the distance from the axis to its inner edge, and by interposing a protruberance between the inner edge of the pivoted member and the guide opening for the rear yarn. This may be so arranged that the arc of movement of the free end of the pivoted member is a semicircle or less, as desired. One such arrangement is exemplified in Figs. 5, 6 and 7. In this instance, there is shown a swinging member 1811 pivotally mounted on a frame piece 15a by means of a screw 17a. The inner surface of the member 18a, as indicated at 24, is so constructed that the distance from its axis to the side edges thereof is greater than the distance from its axis to its inner edge and there is interposed between this inner edge and the guide opening 16a for the inner yarn, a protuberance 25 which, in the present instance, is shown as a part of an annulus 26. As is indicated in Fig. 7, the protuberance 25 limits the inward movement of the outer end of the member 18a.
Since certain changes may be made in the above construction and different embodiments of the invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense.
It is also to be understood that the following claims are intended to cover all of the generic and specific features of the invention herein described, and all statements of the scope of the invention which as a matter of language might be said to fall therebctwecn.
