BOBBIN Filed June 5, 1931 INVENTOR CHARLES E BERH'N MA MM ATTORNEYS;
Patented Oct. 23, 1934 BOBBIN Charles F. Bel-an, Tuckahoe, N. Y., assignor to Celanese Corporation of America, a corporation of Delaware Application June 5, 1931, Serial No. 542,278
3 Claims. (Cl. 242-118) My present invention relates to bobbins, spools and the like used in textile industries and more particularly to bobbins, spools and the like adapted for use in cap spinning operations. The 6 terms bobbins will be hereinafter used to designate spools and tubes as well as bobbins.
In the spinning of yarns of artificial filaments continuously with their production by the cap spinning method, the bobbins are rotated by a suitable spindle construction at very high speeds, namely from 10,000 to 20,000 revolutions and more per minute. When a bobbin has been fully wound, it is removed from the whirl by an operative who immediately places a fresh bobbin onto the whirl which continues its rapid rotation. In this latter operation the bobbin is subjected to especially hard usage for the bobbin is slammed against the rapidly revolving whirland held against it by the operative until the projections or shoulders on the whirl engage a suitable slot in the bobbin.
Cap spinning bobbins, as heretofore commonly constructed, comprised an integral wooden structure turned from a solid blockof wood. These wooden bobbins proved very iinsatisfactory for due to the hard wear to which cap spinning bobbins are subjected, portions of the flanges frequently split off thus making it necessary to 80 discard them as being no longer flt for use.
Another factor which contributed to lower considerably the efficiency and the life of these wooden bobbins was the ease, relatively speaking, with which these bobbins warped, cracked, split and became otherwise defective by reason of deformations caused by changes in climatic conditions.
It is an object of this invention to provide an improved bobbin structure which will be free from the above mentioned and other disadvantages and which will be especially simple in construction and durable and efflcient in use.
Another object of my invention is the pro- 5 vision in a bobbin of the type described of a replaceable bearing member which is adapted to receive substantially all the wear incident to the use of the bobbin and when too worn to be of any further utility may be readily removed and replaced by a new bearing member.
Other objects of this invention together with certain details of construction and combinations of parts will be more particularly described in the specification and pointed, out in the appended claims.
In the drawing:
Figure 1 is a perspective view of my improved bobbin;
Figure 2 is a vertical cross-sectional view of the same and Figure 3 is a cross-sectional view taken on line 3-3 in Figure 2.
Like characters of reference indicate corresponding parts throughout the several views 01. the drawing. 7 r
Referring to the drawing wherein the preferred embodiment of my invention is set forth. the reference numeral 5 generally indicates a bobbin comprising flanges 6 and 7 formed integral with a core, or barrel, 8 upon which the yarn is adapted to be wound. Within the core 8 and formed integral therewith are ribs 9 While but three of such ribs are shown, any desirable number may be used. The ribs are cut away, as is shown at 10, the construction being such that the lower ends of the ribs converge upwardly and thus the ribs form guides as well as bearings for the whirl upon which the bobbin is adapted to rotate. The particular construction of the ribs, as shown in Figure 2, not only makes a lighter bobbin structure but also provides a longer bearing for the spindle thereby causing the bobbin to sit more rigidly on the whirl.
The flange 7 is cut away at 11 to reduce the weight of the bobbin and is recessed at 12 to form a seat 13 which is adapted to receive and retain as by a force fit a bearing member, or bushing, 14. The bushing is apertured at 15 to receive the whirl and is provided with a slot 16 which cooperates with theshoulders on the whirl to rotate the bobbin, as is well understood in the art. The bushing is also provided with an integral annular member 17 which extends into the core 8 and acts as a bearing for the whirl. The flange 6 is provided with an annular groove 95 18 which further lightens the bobbin structure and is also adapted to receive and retain an identification ring, etc. I
It will thus be seen that I have provided an exceedingly durable bobbin structure which will I greatly reduce the expense thereof, the barrel with its integral flanges being practically unbreakable and the bushing which receives substantially all the wear being readily replaceable when worn by a fresh bushing, thus extending 105 greatly the life of the barrel portion of the bobbin.
While my improved bobbin may be formed from any suitable material which is not afiected by climatic conditions, I prefer to make them 110 bobbin abarrelhavingadendthereotapluralityotsubstanverticallyextendingribsadaptedto Itistobeunderstoodthatthei'oreg tailed in said seat, said bushing being adaptedtobereplacedwhenworn.
