and needle when the complete stroke or course 1 of the carrier is completed. The dividers, which are located in the sinkerhead of the machine and positioned between the jack sinkers, are brought forward at the proper moment by operation of thecatchbar motion to therebydivide the stitch.
The present invention has as its object to construct a yarn carrier including an elongated arm having special shapings at both its attached end and at its free end with the shaping at the free or front end arranged to support-a specially shaped yarn guide tube through which the yarn emerges on its way toward its appointed carriage and constructed in a manner to enable the machine to make a stocking of any gauge.
As a further object, the present invention proposes shaping the yarn guide tube so that its free end is hardly more than a self-sustaining circle in a manner to permit close spacing of the guide tubes of adjacent yarn carriers and shaping of the free end of the arm in a manner to facilitate the required close spacing of the guide tubes.
The present invention further proposes a novel means for removably mounting a tube upon the attached end of the arm in end alignment with the yarn guide tube in a manner to guide the yarn from a source to the yarn guide tube.
It is a further object of the present invention to construct a yarn carrier of the type disclosed which is simple and durable, which is effective in use and which can be constructed and sold at a reasonable cost.
For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended claims in which the various novel features of the invention are more particularly set forth.
0n the accompanying drawing forming a material part of the present disclosure:

of the attached end of the yarn carrier taken on the line 2--2 of Fig. 1.
Fig. 3 is an enlarged detailed plan view of the free end of the yarn carrier.
Fig. 4 is a transverse sectional view taken on the line 44 of Fig. 3.
Fig. 5 is a perspective view of the yarn guide tube, per se.
Fig. 6 is a detailed plan view of the arm of the yarn carrier, per se.
The yarn carrier, according to the present invention, is to be mounted in position upon one of the usual carrier rods ll] of a knitting machine, as shown in Fig. 1. The relationship of such carrier rods to the sinkers and needles of a fullfashioned knitting machine is readily known by those versed in the art to which the present invention pertains and, therefore, further details of the machine are not being given in this disclosure as they form no part of the present invention. Details of the construction of the machine and the relationship of the yarn carriers can be obtained from U. S. Patent No. 2,198,081, granted on April 23, 1940, to Gustav Gastrich,
and from the pamphlet Full Fashioned Knitting Machines, published by the Textile Machine Works of Reading, Pennsylvania.
The yarn carrier of the present invention includes an elongated arm i I having a rectangular rear end portion ll and forwardly of that rear end portion, the arm tapers to a front end portion ll of reduced'width. The rear end portion H is provided to be positioned flat on the top face of the carrier rod H), see Fig. 1. Where the arm I 1 extends beyond the carrier rod l 0, it is formed with a smoothly rounded bend l2 to extend away from the rod l0. Slightly inward of the front end portion II the arm [I is formed with a reverse smoothly rounded bend l4 so that the front end portion I I extends back to the plane of the carrier rod and toward the needles of the machine.
Immediately forward of the band 52, the arm II is formed with an aperture [5 of relatively large dimensions and forward of the aperture [5, the arm II has a second smaller aperture [6. The apertures l5 and I6 are arranged on the longitudinal axis of the arm II, see particularly Fig. 6.
Between the aperture l5 and the rear edge of the rear end portion H the top face of that rear end portion is formed with a shallow groove I I, see Figs. 2 and 6. The groove I1 is formed on the longitudinal axis of the arm II and is provided for seating a tube l8 on the longitudinal axis of the arm ll. Extended laterally across the rear end portion of the arm ll, there is a clamp strip 19 formed intermediate of its ends with a upwardly rounded portion 20. The upwardly rounded portion 20 is provided for snugly fitting over the top of the tube l8 where it extends from the groove H, as best shown in Fig. 2. The clamp strip [9 on opposite sides of the upwardly rounded portion 20 is formed with holes 2| aligned with complementary holes 22 formed in the rear end portion of the arm I I on opposite sides of the groove 11. Screws 23 having washers 24 beneath their heads, are passed freely through the aligned holes 2| and 22 and threaded into complementary holes 25 formed in the car-. rier rod 10. Thus, the screws removably attach the rear end portion ll of thee-rm H; the carrier rod l0 and mount the clamp strip [8 inv a fixed position in which the tube I8 is held in position in the groove ll. By slightly loosening the screws 23, the tube Hi can be slipped from beneath the upwardly rounded portion 2a: of the clamp strip [9 to be replaced: by:- a new tube without requiring complete removal of the yarn carrier from the carrier rod to;
The rear end ofthe. tube l8 has: an outwardly flared portion l8 for facilitating. threading of theyarn from asourcethroughthe tube It and from the tube l8 to a yarn guide tube 2.6 sup.- ported upon the front end: portion ll of the arm I I. Intermediate of its ends, the yarnguide tube 2b: is formed with an'integral stop-block 21. which divides thetube 26. intoa rear mountingportion zfiaand a front end. portion 2.6,
The front end portion N of the arm H, forwardly of the; bend Misformed withan. aperture 28; Forwardly of the aperture 2-8;, the. front endof thearm- II is, formed with a notch 29- of? a size. to snugly receive the stop. block 21 of the yarnguide tube- 25- to hold the tube against. rotation, The: material: of the front endportion of the arm. ll between the. aperture 2'81and the;
notch-2,9,, formed with a, bore 3010f a. diameterslightly smaller than the outside; diameter; of the rear mounting, portion: 26a of the yarn guide tube 26". Parallel with the bore Stand; traversing the; bore, the, arm it between the; apertur 28 The and the notch 29 isiormed with a slit 3i. slit 3; I permits thematerial of the front; end portion HP- on opposite sides oftheslit to spread apart astho rear mounting portion; 2 6% of the. yarn guidetubelfi is forced; into the bore 3.0 as shown in Fig. 3. Inward: insertion of the. rear:
mounting, portion 2-6 is stopped when the stop end of the tube It, passes through the aperture l5 thenalong the bottom face of the arm II,
to the aperture l6 and then along the front face of the arm H to the. upper endof tube 26,. The
4 yarn enters the upper end of the yarn guide tube 26 passing therethrough and from the front end of the yarn guide tube to the sinkers and needles of the knitting machine as is generally known in the art.
The formation of the end of the front end portion 26 of the yarn guide tube 26 forms a taper 32, see Fig. 5;, at thefmntor. lower end of the tube from which the yarn emerges on its way to the appointed needle of the machine, as already stated. Thus, the front or lower end of the yarn guide tube 25 is hardly more than a self-sustaining circle so that the yarn carriers required by a single machine can be mounted Withtheir arms andyarn guide tubes placed very close together and yet without giving rise to the heretofore-encountered troubles and dangers relative to wear, breaking and mutual entanglement of adjacent yarn lengths, and even breakage of the ends of the arms andy-arn guide tubes themselves.
