YARN RACK FGR CERtIUhAR KNKTTKNG MACHINE Sam Mishco'n, Bell Harbor, Lester Mishcon, Woodmere, and Harry Agulnelr, Brooklyn, N. Y., assignors to Supreme Knitting Machine (In. inn, Erooidyn, N. kl, a corporation of New York Application February 5, 1954, Serini @359 9 fiisims. (Cl. 66-4125} This invention relates to circular knitting machines and has particular reference to an improved yarn rack for carrying the yarn cones for such machines.

In the conventional type of circular knitting machine presently in use, radiating bars which form a part of the yarn rack and support the yarn cones, are arranged on one level and as close to the floor as is possible and still allow head clearance for an attendant to pass thereunder when it becomes necessary to replace a part, adjust or repair the machine. An attendant or mechanic when making repairs or adjustments to the machine must work under the yarn rack and, unless he is a very short individual, finds it impossible to stand erect and as a consequencefinds it uncomfortable working on the machine.

It is a'primary object of the present invention to provide a yarn rack so constructed so as to provide ample head room for the attendant making adjustments or otherwise working upon the machine, thereby eliminating any discomfort to him during his activities upon the machine.

Another fault which exists with the yarn racks presently in use is the difficulty encountered in removing used yarn cones and their replacement. A further inconvenience is the difiiculty in observing, from the floor, yarn cones upon the yarn rack which require replacement.

It is a further object of the present invention to provide a yarnirack in which the yarn cones are so arranged uponthe yarn rack as to be clearly visible by an attendant from the floor as he passes the machine and the ease with which replacement of the cones may be effected.

A further object is to reduce the amount of damage to the knitted cloth and the down time because of the ready accessibility and visibility of the yarn cones. Because of the arrangement of the cones and the canopy like compartment under the yarn rack much lost time and motion is eliminated.

The essential feature of this invention resides in the provision of a yarn rack comprising a series of yarn cone carrying rings which are supported by sloping ribs radiating outwardly from the central portion of the machine upon which the yarn cones are mounted and arranged in a stepped up formation, in such manner, that the inner cone carrying ring is higher than the outer cone carrying ring.

The present construction and arrangement provides a canopy or umbrella-like compartment under the yarn rack and affords ample head room for the tallest attendant who may work upon the machine parts.

This arrangement also brings to view to an attendant walking around or past the machine all of the mounted cones and enables him, as he moves around the machine to quickly spot any cones which need replacement.

As this invention may be embodied in several forms without departing from the spirit or essential characteristics thereof, the present embodiment is therefore illustrative and not restrictive, since the scope of the invention is defined by the appended claims rather than by the description preceding them. and all changes that fall within the mctes and bounds of the claims or of forms that are 23?,1 1? Patented ffigy. i3, 395% their functional as well as conjointly cooperative equivalents, are therefore intended to be embraced by those claims.

The invention itself, however, both as to its organization and its method of operation, will best be understood from the following description of a specific embodiment when read in connection with the accompanying drawing, in which:

Fig. 1 is a side elevational view of a circular knitting machine, showing a portion of the yarns with the mechanism of the lower base portion of the knitting machine omitted.

Fig. 2 is a half plan view of the yarn rack with parts of the machine omitted, and

Fig. 3 is an enlarged fragmentary sectional detail through the yarn rack and guide holder taken approximately along a plane indicated by the line 33 of Fig. 2.

Referring in detail to the parts in which similar reference numerals refer to similar parts throughout, 10 designates, in general, a circular knitting machine of which the lower portion including the legs 12, top plate 14, and yarn rack supporting standards 16 only, are shown. The upper ends of the standards are held together by means of a spider l8.

The lower end 20 (Fig. 3), of a radially extending rack arm or bracket member 22 is the receiving member for

carrier rings

24, 36, 38 and 40. The said bracket member 22 extends slantingly upward and terminates in an angularly bent portion 26 (see Fig. 3), which rests upon and is secured to a ring 28. At least three bracket members 22 are provided.

Spaced apart

lips

30, 32 and 34 are provided by cutting out portions of the bracket member 22 and bending them outwardly to form supports for cone carrying

rings

36, 38 and 40 which in turn respectively carry

yarn cones

42, 44 and 46. The outer ring 24 carries spaced apart yarn cones 48. The

yarn cones

42 and 44, positioned between the yarn cones 48 on the lowest plane and the yarn cones 46 on the highest plane, have their largest or lower diameters overlapping in a vertical plane the yarn cones of the lower succeeding horizontal plane or line of yarn cones. This is readily seen in Fig. 3 where the dotted lines of yarn cones 44 overlap, in the vertical plane, the yarn cones 42, and likewise yarn cones 42 overlap, in the vertical plane, yarn cones 48. Such overlapping of

yarn cones

44 and 42 is also readily seen in Fig. 2.

Yarn guide rings

50, 52, 54 and 56 having porcelain eyelets 58, are attached to and are supported upon

lips

60, 62, 64 and 66, said lips being formed upon bracket arms ,68. The said bracket arms are secured to and extend radially from supporting standards 70 which are mounted upon the bent end 26 of the said rack arm or bracket member 22 as shown at 72 in Fig. 3. Each of said rack arms or bracket members 22 carry one of said bracket arms 68.

The level above the floor of the outer lower cone carrying ring 24 is approximately the same as that of the conventional circular knitting machine. The next inner ring 36 is somewhat higher than the ring 24, and the two succeeding

rings

38 and 40 are successively higher than its preceding ring while the connected supporting bracket member or rack arm 22 assumes a line approximately parallel to the steps formed by the said cone carrying rings thereby creating a canopy or umbrella-like formation beneath the yarn rack which affords ample head room for anyone working upon the machine.

The stepped up arrangement of the yarn cones brings them into view of an observer from the outside of the machine or from a position under the canopy. It also provides easy access to the yarn cones when replacement becomes necessary.

The various yarns Y are fed from the cones (Fig; 1) through the eyelets 58 upon the

guide rings

50, 52, 54 and 56 thencenxp to a collector ring 74 and through eyelets in same down to a spacer ring 76 and finally down to the knitting needles in the base portion of the knitting ma chine (not shown).

While the device illustrated shows a yarn rack for one hundred and twenty eight cones the rack may be adapted to receive any number of cones.
