BOBBIN 0R YARN PACKAGE HOLDER Harvey E. Herr, Buffalo,` N. Y., assigner to Herr Manufacturing Company, Inc., uialo, N. Y., a corporation of New York y. Application January 20, 1939, Serial No. 251,984

5 Claims.

'Ihis invention relates to certain new and useful'l improvements in the bobbin or yarn package holders used in the spinning art.

It has for one off its objects to provide a holder. of this character which has been designed the thread' is taken off' the bobbin and thereby eliminate snarling, knotting or breaking of the threads.

Other features of the invention reside in the construction and arrangement of parts hereinafter described. and particularly pointed out in the appended claims.

In the accompanying drawing:

Figure 1 is a fragmentary front View of a portion of a spinning machine showing my improved b-obbin holder structure associated therewith. Figure 2 is an enlarged central longitudinal section of the bobbin holder and associated parts. Figure 3 is a top plan View of the bobbin holder. Figure 4 is an enlarged vertical section taken on line 4 4, Figure 2. Figure 5 is an exploded perspective view of the bobbin holder elements.

Similar characters of reference indicate corresponding parts throughout the several views.

Referring now to the drawing, Ill indicates the bobbin-spindle, II the take-off bobbin mounted thereon, I2 the flyer-body on which the flyer wires I3 are mounted for guiding the threads from the lbobbin to a guide or centering eye I4, from which the threads lead to a takeup spool (not shown). The flyer shown is of the eccentric type and the core or barrel I5 of the bobbin holder has a recess I6 in its top having an inverted cup-like opening I'I therein arranged concentric to the axis of the bobbinspindle.

'I'he package of silk-rayon or like material to be spun is an open-ended one and consists of a sleeve I8 having the material I9 wound thereon in a manner to provide substantially conical or beveled ends 20 radiating from the companion ends of the sleeve, as shown in Figure 2. These conical ends of the package may be deflected either inwardly or outwardly. The bore of the package-sleeve is somewhat larger in diameter than that of the barrel I5 so as to be readily applied thereto and removed therefrom.

Secured to the lower end of the barrel I5 by screws or like fastenings is a head-plate 2i which is of a diameter toV extend somewhat beyond the edges of the package I8, I9 and which is preferably'dished or of inverted conical shape, as shown in Figures 24 and 5. Extending about the lower end of the barrel and rising axially from this plate is a collar or `ferrule 22 which extends into the package-sleeve I8 to frictionally hold the package on the barrel. After the package is applied to the barrel, a plate 23 may be placed over its top to keep the package clean, such plate having a collar 24 thereon which frictionally binds it between the barrel and the sleeve I8.

Disposed over the top side of the head-plate 2l for yieldable bearingengagement with the opposing end of the package I9 isa resilient diaphragml or' ring-like plate 25 of thin metal which is retained at its periphery to the marginal edge or in an inwardly-facing annular groove formed in the head-plate by a hanged band or collar 25, while its inner portion is freefloating. Normally this diaphragm spans the dished head-plate in a horizontal plane so that suii'icient space is provided for the yieldable displacement of the diaphragm toward the plate, in the manner shown in Figure 2. When the package is applied to the barrel, the lower end of the package abuts the yieldable diaphragm 25 and aords an effective seal or joint at the lower outer edge of the package for preventing the threads from the package working under the bottom thereof during the spinning operation. As the thread is payed off the package, the resilient diaphragm follows in close contact with the conical bottom of the package and always forms a closed joint at the peripheral edge thereof. While the periphery of the diaphragm is retained by the flanged band 26, the connection is such that the diaphragm is comparatively free for the full displacement required. About its center opening this diaphragm has a flange 21 which bears against the paper sleeve I8 of the thread package so as to allow all of the thread to be unwound therefrom during the twisting operation.

To prevent the thread from running over the upper end of the package, the take-off flyer wire I3 with the depending eye is so disposed that such eye is always located below the upper end of Vthe package.

By preference, the flyer body I2 is provided with a suitable brake element 28 which may be thereof, said head-plate havingan inwardly-fac-- ing annular groove at its outer edge and being substantially of conical shape, and a flat resilient metallic diaphragm-like member freely supported at its periphery in said plate groove for bearing engagement with the opposing end of the package.

2. A bobbin or yarn package holder, comprising a barrel having a head-plate fixed at one end thereof, said head-plate being substantially of conical shape and having a retaining band at its periphery forming an inwardly-facing annular groove, and a normally flat resilient diaphragm-like member of thin metal disposed over said head-plate for iioating movement relative thereto and in loose-fitting engagement at its periphery with said retaining band groove.

3. A bobbin or yarn package holder, comprising a barrel having a head-plate at one end thereof, a resilient diaphragm-like member superposed on said plate for displacement axially of the barrel into yieldable bearing engagement with the opposing end of the thread-portion of the package, said `diaphragm member having va flanged inner portion about the axis thereof for bearing engagement with the core portion of the package, and means applied to the head-plate including a collar having an inwardly-facing groove for anchoring said diaphragm member at its periphery to said head-plate, said means per'- mitting a free displacement of the diaphragm at all times.

4. The combination with a bobbin-spindle and an open-ended package of material to be spun, of a package-receiving barrel adapted for attachment to said spindle and having a head-plate at its lower end of inverted conical shape, a retaining band at the periphery of the head-plate and having an inwardly-facingY annular` groove therein, a collar extending about the lower end of said barrel for frictionally retaining the package thereon, and a resilient diaphragm of thin metal superposed on said head-plate and loosely tted -at its periphery in the groove of said retaining band, the remaining portion of the diaphragm spanning the opposing face of the headplate in spaced relation thereto for displacement axially toward the same and adapted for sealing bearing engagement with the lower end of the package.

5.- A yarn package holder of the character de.- scribed, comprising a package-receiving barrel adapted for attachment to the bobbin-spindle, a head-plate secured to the bottom of the barrel about the spindle and projecting upwardly and outwardly therefrom in substantially inverted conical fashion and against which the lower end of the package-sleeve is adapted to abut, the periphery of said plate having an inwardly-anged retaining band applied thereto forming an annular groove, and a resilient ringlike plate of thin metal superposed on said headplate and having its marginal edge loosely seated in said retaining band groove and its body portion spanning the opposing face of the headplate in spaced relation thereto for displacement toward the same and adapted for sealing bearing engagement with the lower end of the package about its sleeve.
