To all whom it may concern:

Be it known that I, CARL J. ULMANN, manufacturer, a citizen of the United States, and resident of the borough of Manhattan, city, county, and State oiLNew York, have invented a certain new and useful Im rovement in Packages of Yarn and the 11 e, of which the followin is a specification.

My invention re ates to packages of yarn and the like and has for its object to provide an improved package in which the yarn or the like is wound in the form of a ball in a novel manner. My improvement further 00111181111918.1388 the provision of a package of yarn or the like in which the inner end of the yarn or the like is readily accessible for unwinding purpose and in which the danger of tangling or the like during unwinding is reduced to a minimum. Other objects of my invention will ap car from the description hereinafter an the features of novelty. will be pointed out in the appended claims. The present application 1s a division of another a plication filed by me in the United States Tatent Oflice on July 6, 1915, Serial No. 38097.

An example of my improved arrangement upon which my improved package may be produced is shown in the accompanying drawings in which Figure 1 is an elevation with the core on which the yarn or the like is wound shown in section; Fig.2 is a vertical section showin the completed ball of yarn or the like; *ig. 3 is a similar vlew showing said completed'ball in the act of being removed from the device; Fig. 4 1s a plan view of Fig. 1; and Fig. 5 is a horizontal section on the line 5-5 of Fig. 2.

As shown in the drawings the device comprises a preferably cylindrical head or carrier 10 having an axial recess 11 at one end for the accommodation of the usual rotary shaft or pindle 12 forming part of a balling or winding machine, any sultable means, such as for instance a screw 13, being provided for securing the head 10 upon the shaft 12 so as to rotate therewith. At its other end the holder 10 is provided with longitudinal slots 14 preferably arranged 1n diametrically opposite pairs and extending radially and inwardly into communication with an axial chamber 15, the said slots lfl and chamber 15 beginning at an intermediate poiut of: the holder 10 and terminating "in the free end face thereof as shown in Fig. 2. A member 16 is slidably mounted within the chamber 15 and is preferably provided with peripheral projections 17 which extend into the slots 14, the said member 16 being secured to the inner end of a rod or stem 18 which projects slidably through a bushing 19 secured in the outer end of a said chamber 15 and at its outer end carries a clamping plate 20 as shown in Fig. 2. The parts are so arranged and proportioned that in the normal condition of the device the member 16 will be located near the inner end of the chamber 15, while the plate 20 will rest against the free end of the holder 10, said plate 20 projecting over the ends of the slots 1 1 as also illustrated in Fig. 2. The member 16 and plate 20 are maintained in and returned to thi normal position for instance by means of a coil spring 21 which surrounds the rod or stem 18 and bears with its opposite ends respectively against the bushing 19 and the member 16. The arrangement further includes fingers 22 which are pivoted at 23 in the slots 14, each of which contains a pair of finger located respectivel near the inner and outer ends thereof an having cam surfaces 24; extending respectively beneath the plate 20 and the projections 17 and terminating at shoulders 25 formed on said fin gers as shown in Fig. 2. These fingers 22 normallyoccupy a position at substantially right angles to the axis of said device or in other words project radiall from the slots 14, the pressure of the Pl'OjGCtlOIlS 17 upon the cam surfaces 24: of the lower fingers 22 under the influence of the spring 21 serving to maintain said lower fingers in this position, excepting when a force suflicient to overcome the tension of said. spring is exerted toward the free end of the carrier. The upper fingers 22 are similarly maintained in their extended positions by means of the plate 20 which exerts a pressure upon the cam surfaces 24 thereof through the medium of said spring 21. The said fingers 22 are further provided with angular or squared ends 26 which are arranged to en gage the bushing 19 and cooperating portions of the carrier 10 as shown in Fig.2, whereby the pivotal movement of said fingers 22 toward their extended position is arrested or said fingers may engage the inner end walls of the slots for the same purpose, it being understood that any other arrangement producin the sameresult may be substituted if desired. The fingers are otherwise so shaped as to permit a pivotal move- 'ment thereof in the opposite direction toward their folded osition.

In usin the device a tubular core 27 ofany suita le material such as cardboard and preferably having a substantially uniform inner diameter throughout its length is placed over the fingers 22, it being understood that the inner diameter of said core relatively to the distance between the outer ends of each pair of diametrically opposite fingers 22 when the latter are in their horizontal position, issuch that a frictional engagement between the inner surface of said core and the ends of said fingers is secured. In this manner the core 27 is firmly secured upon said fingers 22 so as to rotate with. the carrier 10 as the shaft or spindle 12 is rotatably actuated by means of any suitable mechanism. It will'be seen that the tubular core 27 is of considerably larger diameter than the diameter of the carrier 10 and is a true'tube or cylinder of substantially even diameter throughout and without any end flanges or other projections. The yarn or the like 28 which is to be wound upon the core 27 substantially in the form of a ball may have its one end located beneath the plate 20 so that said end is firmly clamped between said plate and the free end of the carrier 10 or said end may be otherwise secured, after which the winding operation is commenced by applying power to the shaft or spindle 12., The wlnding operation may be carried out in the usual manner excepting that the said yarn or the like is also wound over the opposite ends of the core 27 to form inwardly extending portions 30 in addition to-the portion 29, the lower one engaging the carrier 10 and both inwardly overhanging the ends of the core 27 as shown in Fig. 2. After the desired amount of yarn or the like 28 has been wound on the core 27 to roduce a ball of the desired size the win in'g operation is discontinued and a pressure toward the free end of the carrier 10, sufficient to overcome the tension of the sprin 21, is exerted on the completed ball. T is will cause the fingers 22 to swin on the pivots 23 as shown in Fig. 3 so that t e core 27 is released from frictional engagement therewith, the operation at the same time, through the medium of the cam surfaces 24-, acting upon the plate 20 and the projections 17 of the member 16 and moving said plate 20 away fromthe free end of the carrier 10 and thus releasing the heretofore clamped end of the yarn 28. A continued movement of the completed. ball toward the free end of the carrier 10 will finally cause the inwardly extending portion 30 to engage the lower fingers 22 and thereby cause a continued pivotal or folding movement thereof and a continued axial movement of the combined member 16, rod 18 and plate 20 until finally said lower fingers 22 will lie entirely within the slots 14: as shown by dotted lines in Fig. 3. In this condition of the parts the projections 17 of the members 16 are located beneath the shoulders 25 of the lower fingers 22 and the ball of yarn or the like is free to be moved outwardly on said carrier 10 beyond said lower fingers 22. To completely remove said ball of yarn or the like from the carrier 10 the axial movement of said ball toward the free end of said carrier is continued until the upper fingers 22 are likewise swung or folded inwardly by said inwardly extending portion 30 so as to He entirely within the outer periphery of said carrier 10 whereupon said ball is free to be completely withdrawn from said carrier as will be clearly apparent. As soon as said Portion 30 of the ball has passed b lr the fingers 22 the latter will be returned to their outspread, horizontal position by the pressure of the plate 20 .and the projections 17 upon the cam surfaces 24 of said fingers, due to the influence of the spring 21. It will be seen that the initial pivotal movement of the fingers 22 as the ball is being removed immediately causes a movement of the plate 20 away from the free end of the carrier so that the end of the yarn which is clamped beneath said plate during the winding operation is quickly released and does not interfere with the removal of the completed ball or cause an unwinding thereof.

\Vith my arrangement the core 27 is firmly held against dislocation throughout the entire winding operation, as the tension exerted by the yarn and possibly tending to pull the core and partl completed ball from the carrier is never sufli cient to overcome the tension of the spring 21. The danger of an interruption of the winding operation before the same has been fully completed or an unintentional dislocation of the core'and partly completed winding wherebythe Whole ball structure is destroyed is thus entirely avoided and a loss of yarn owing to the same becoming entangled is done away with. Furthermore a more firmly and securely wound ball is produced with my improved device than has heretofore been possible while the inner end of said yarn is made readily accessible whereby an unwindmg of the yarn under the most favorable conditions is possible with the danger of tangling or the like reduced to a minimum. VYith my improved device it is further possible to produce a ball of yarn having an enlarged hollow interior and two inwardly overhanging end portions forming reduced end openings communicating with saidinterior. In addition to this the core is more firmly held on the carrier than has heretofore been possible and yet at the same time is removable therefrom in a simple and efficient manner and with a minimum of effort, so that the possibility ofdestroying or disarran 'ng the winding during the removal o the ball from the carrier is also obviated.

Various changes in the specific form shown and described may be made within the scope of the claims without departing from the spirit of my invention.

I claim:

1. The combination of a tubular core having substantially the same internal diameter throughout its length, and a ball of yarn or the like initially wound to overlap both ends of said core to a considerable extent.

2. A package of yarn or the like comprising a ball initially wound to produce a hollow interior and opposite end openings, the diameters of said end openings being less than that of the hollow interior.

3. A package of yarn or the like comprising a ball initially wound to form a hollow interior and opposite end portions inwardly overhanging said hollow interior and forming reduced end openings, and means for maintaining said ball against collapsing.

In testimony whereof I have hereunto set my hand.

CARL JOSEPH ULMANN.
