BOBBIN HOLDER Robert Rulon-Miller and Warner H. Tabor, Bristol, R. l.,
assignors to Dixon Corporation, acorpor:.tion of Rhode Island Application .lune 3, 1954,'Serial No. 434,142
v8 Claims. (Cl. 242.130)
This invention relates to a bobbin holder of the type used for supporting a 'bobbin vfrom the underside of the top board of the creel o f a spinning .frame or a .roving frame.
Pendant type bobbin holders usually have ybeen supported rotatably by means of ball bearings located outside of the bobbin and directly beneath `the top board of Vthe creel with a part which extends into the open center of the bobbin vdepending from this ball bearing for .frictionally engaging .the inner walls of the bobbin. There is considerable lint present around the creel of a spinning frame, and this lint settles on the ball bearings and their supports, thus increasing friction of the bearing, .and is difficult to clean. Further, the use Vof Va ball bearing requires that a brake .be used to Vretard turning. l.
One of the objects of this Vinvention -is to completely house .the bearing for the bobbin holder' within .the bobbin so that it will be protected from lint and thus will Vnot .be 'hampered by friction which results therefrom.
Another object of the invention is to provide a device which willi turn easily without the necessity of providing ball bearings, which are expensive.
Another object of the invention is to provide an arrangement which will need no'b-rakfe to control dhe rotation of the package.
Another object of the invention is `to provide an arrangement so that the bohbinholder may be adapted ,for use with man y different diameter ibo'bbins.
Another object of the invention is lto provide an .arrangement so that the bobbin holder may be fsl'iilttedor use with one size bobbin or for use with another size bobbin by a simple manual operation.
With these and other objects in view, the invention consists of Icertain novel features of construction as will be more fully described and particularly pointed out in the appended claims.
In the accompanying drawings:
Figure 1 is a sectional view of an enlarged scale showing a portion of the bobbin as secured in position by a holder employing this invention and illustrating the parts in position for receiving a smaller size bobbin;
Figure 2 is an elevation of the bobbin holder alone looking at right angles to the view of Figure 1;
Figure 3 is a section of the bobbin holder alone with the parts in position for taking a large size bobbin;
Figure 4 is a section on line 4-4 of Figure 2;
Figure 5 is a section on line 5 5 of Figure 3;
Figure 6 is a section on line 6-6 of Figure l;
Figure 7 is a perspective View of the control member for changing the bobbin holder from one to receive a large bobbin to one to receive a small bobbin.
With reference to the drawings, 1l) designates the top board of a creel of a spinning frame or the like from which my bobbin holder is suspended in pendant relation.
The bobbin holder comprises a head 11 having a threaded bore 12 into which screw 13 extends through opening 14 in the top board 10 of the creel of a spinning frame. The head 15 of the screw engages the margin nited States Patent ice about the hole 14 and serves to draw the head 11 up against the under side of the .top board so as to `be substantially rigid therewith. The bore extends completely through the head 11 and is reduced as at 16 and again reduced .at its lower end as at 17. The surface 18 between 'the bores 16 and 17 is formed on the arc of a sphere and a ball .19 is located in the bore 16, which ball is substantially the same size as the bore `16having its bearing on the shoulder 18. Pin 20 extends through the opening v17 and is much smaller than this opening land has a forced t with the ball 19 allowing rocking motion laterally of the axis of the head and 'bore in a swivel-like fashion.
The bobbin holding member designated generally 21 is formed of a single piece of sheet stock bent into a tubular form and comprising a body 22 having a hollow center 23. At diametrically opposite points slots 24 are provided, with which slots arms 25 register. These arms 25 extend generally downwardly from the upper portion of the body .22 extending from the end edge of the slot 24 and are formed of the same stock as this tubular body, the stock beingin continuation from the upper end of the slot and being bent outwardly as at 26 and then downwardly as 'at27 with the ends curving outwardly as at 28. These 'arms are arcuate in cross section to stifen them 'and of Ja size smaller than the Width of the slot 24 and may be freely flexed into the slot to the dotted line position shown in Figure l.
At the lower end of the cylindrical tube 22 there is positioned the control member 30 which is shown in perspective in Figure 7. This control member has a cylindrical body portion 31 which has an annular recess 32 in its surface. This cylindrical portion 31 is of a size substantially the size of the interior surface of the cylindrical tubular 'body 22 Vand 'is rotatably mounted therein. It is prevented from being withdrawn from the end of the Ebody b y fingers 33 located at diametr'ically opposite points of the tubular member being turned into the slot 32 vso as to retain this control member in -place yet permit 'it torota'te. This control member is provided with two upstanding projections 34 located at diametrically opposite portions of the member and providing a `slot 35 between them. These projections are of a height so that when the projections 34 are turned into registration with the slot 24, the arms 2S will engage -these projections 34 and block the entry of the arms '25 into the slot as shown in the position illustrated in Figures 3 and 5. However, when the control member 3G is turned at right angles to this postion, as shown in Figures 2 and 6, then arms 25 are free to move through the slots 24 into the space 35 between the projections, as shown in the dotted line position of Figure l, and when in this position, the arms may take a smaller bobbin or one having a smaller central bore. When the arms are in engagement with the projections 34 so as to hold them outwardly, a larger bobbin will be accommodated and still the arms may ex by sliding along the projections 34.
An abutment 41 is provided on the pin 2) which engages the anti-friction washer 42 formed of any suitable anti-friction material. This washer in turn engages web 37 extending across the tube 22 with projections 38 entering slots 39 in the walls of the tube. This abutment 41 is made small so as to reduce resistance of the bobbin holding member 21 to turning with the bobbin. Relative rotation is between washer 42 carried by member 21 and the abutment 41. The ball 19 does not rotate with the bobbin. The lower end of the head is rounded or cut away as at 51 so as to allow full rocking movement of the pin 20 by reason of its ball mounting 19. Thus, in forcing the bobbin on to the holder 21, should there be a force out of line with the axial center of the bobbin, the contact of the face 22 of the holder with the rounded end 51 of the head will be at a location to better support a thrust of this character.
The bobbin will have wound on it a package 45 and as the yarn is drawn from the outer surface of the package 46, the turning force will be a multiple of the pulling force times the distance 47 that the yarn is located from the turning axis of the bobbin. The resistance to this force which tends to turn the package will be the weight of the package multiplied by the co-eficient of friction between the abutment 41 and the washer 42 multiplied by the radius of the abutment 41, which radius we have designated by the arrow 48. Thus, it will be apparent that in order to have a low resistance to turning, we will maintain the radius 4S as small as possible consistent With the necessary strength to support the parts, and to do this the pin 20 will also be made small.
It will also be noted that when the bobbin is full and weighs the most, the radius 47 is the greatest, affording the greatest turning moment, whereas when there is less yarn on the bobbin, the radius 47 is the smallest. Thus, there is a tendency to equalize the force required throughout the use of the package. As the resistance to turning and the weight of the package always have an opposite relationship as to sizes, the resultant turning force required is always the same.
In order to assist in the provision of a lint free bearing, we provide a cover 49 having a flange 50 which is slidable on the head 11 and closes the bore of the bobbin at the top, thus resting on the bobbin and turning with it. Further, we provide a ange 53 on the head, which will catch lint should it enter the bobbin opening and arrange that the upper edge 52 of the bobbin holder `come close to this ange to avoid lint entering the bobbin holder.
By this arrangement we lind that the resistance to turning is small, making the ball bearing unnecessary and yet sufficient s0 that a brake is unnecessary.

A bobbin holder comprising a tubular body having slots therethrough, resilient arms outwardly of the body connected to said body and located in registry with said slots and movable therethrough upon flexing, and abutments carried by said body and rotatable relative thereto into and out of registry with said slots to selectively block or permit the moving of said arms through said slots.
