A known procedure of salvaging bobbins which have become worn is that of turning the butt portions to a diameter smaller than conventional size and then applying a wear resistant plastic cap to the butt. New bobbins may also be given a wear resistant cap to reduce wear. Many textile mills are reluctant to purchase newbobbins to incorporate thisfeature for relative to the cost of conventional bobbins it would be economically prohibitive. Additionally a considerable amount of weight is added to a bobbin by reworking it in this manner and is not considered an acceptable solution for obvious reasons.
The improved textile bobbin according to the present invention is of standard configurationand by providing a means integral with the butt thereof to prevent-premature wear without adding excessive weight or cost, 1
the life expectancy has been substantially increased relative to conventional bobbins utilized with automatic yarn winding devices.
SUMMARY OF THE INVENTION The textile bobbin of the present invention is conventional in appearance and includes the usual butt portion and integral therewith a barrel of lesser diameter extending from said butt portion.
A plurality of wear resistant insert members are mounted in the butt portion and are disposed so as to communicate with and form apart of its end surface opposite that from which the barrel extends. These wear resistant insert members are arranged in spaced relation adjacent the peripheral edge of the end of the butt portion. When a bobbin is presented to the yarn winding apparatus, the insert members are caused to make frictional contact with'that portion of said apparatus which effects rotation of the bobbin thereby substantially reducing the amount of frictional wear upon a bobbin in this area.
It is a general object of the invention to provide an improved bobbin for use in a yarn winding apparatus having an increased life expectancy relative to bobbins of the prior art-and which is resistant to wear upon its butt portion.
A further object is to provide improved wear resistant bobbins for automatic winders which can be fabricated without prohibitive increases in cost and added weight.
These and other objects of the present invention will become more fully apparent by reference to the appended claims and as the following detailed description proceeds in reference to the figures vof drawing wherein:
BRIEF DESCRIPTION OF THE DRAWING FIG. 1 is a view in side elevation of a textile bobbin to which the wear resistant insert members have been applied.
FIG. 2 is an end view on an enlarged scale of the bobbin butt portion showing the location of the insert members,
FIG. 3 is a view in side elevation on an enlarged scale of the bobbins butt portion with a portion thereof broken away to show the preferred angular position of an insert member assembled therein, and
FIG. 4 is a sectional view on an enlarged scale showing the relationship between the bobbins butt portion and that part of the looms yarn winding apparatus adapted to rotate a bobbin for the building of a yarn package thereon.
DESCRIPTION OF THE PREFERRED EMBODIMENT As the general construction and operation of an automatic yarn winding apparatus is known and familiar to those conversant in the art and as the invention is entirely concerned with an improved bobbin for use in such an apparatus, it is only considered necessary here to illustrate and describe that portion of the apparatus directly concerned with a preferred form of the invention.
Referring to FIG. 1, a textile bobbin generally indicated by numeral '10 is shown and includes the usual butt portion lland a barrel 12 of lesser diameter extending therefrom. The butt portion 11 is provided with a plurality of ring members 13 that are effective in properly positioning a bobbin within a loom shuttle as is well known to those skilled in the weaving art.
That end of the bobbins butt portion identified by numeral 14 is provided with a plurality of wear resistant insert members 15 and are preferably fabricated from a plastic material such as nylon, although any other suitable wear resistant materialcould be used as well. These insert members 15 are in peg form and are assembled in holes formed at an oblique angle to the axis of the bobbin in the end of the butt portion 11. The insert members are of a length whereby the outer ends communicate with and form a part of the end 14 of the butt portion 11. i
As shown in FIG. 2, the butt portion 11 is provided with three equally spaced insert members 15 and it should be understood that any desired number of such inserts may be utilized.
In FIG. 4, numeral 16 identifies a turning cup that is one of the many parts of the automatic yarn winding apparatus and being rotatably driven by a means not shown is effective in rotating the bobbin 10 for the pur pose of building a yarn package upon the barrel 12. The outer ends of the insert members 15 are disposed in such a manner about and adjacent the peripheral edge of the end of the butt portion 11 so as to frictionally engage the inner tapered walls 17 of the turning cup 16. Engagement of the ends of the insert members 15 in this manner substantially retards frictional wear ing of the end 14 of the bobbin butt portion.
To summarize the operation, a bobbin upon near depletion of its weft yarn is ejected from the loorn shuttle and replaced with one which is fully wound. The spent bobbin after being stripped of its few remaining winds of yarn is carried to a position where it is automatically presented to the loom s yarn winding apparatus to then build another yarn package on the barrel thereof. After completion of the yarn package the bobbin is automatically removed from the winding apparatus and is subsequently transferred back into the loom s shuttle and the cycle is again repeated. The wear resistant feature if the bobbins butt portion has greatly reduced wear on the end of the bobbin butt that was caused by its frictional engagement with the turning cup 16 of the winding apparatus and has substantially increased the life expectancy of textile bobbins.
Although the present invention has been described in connection with a preferred embodiment, it is to be understood that modifications and variations may be resorted to without departing from the spirit and scope of the invention as those skilled in the art will readily understand. Such modifications and variations are considered to be within the purview and scope of the invention and the appended claims.
I claim:
1. A textile bobbin for use in an automatic yarn winding apparatus on a loom, said bobbin having a butt portion and a barrel of lesser diameter extending therefrom upon which a yarn package is wound, a plurality of wear resistant peg members assembled in said butt portion and extending therein at an angle oblique to the axis of said bobbin, each of said peg members having an end surface communicating with and forming a part of the outer peripheral end of said butt portion opposite said barrel for engagement with the yarn winding apparatus during the building of a yarn package on said barrel.
2. The textile bobbin according to claim 1 wherein said wear resistant peg members are fabricated from a wear resistant plastic material.
