Perkins & Son, Inc., Holyoke, Mass, a corporation of Massachusetts Application January 15, 1937, Serial No. 120,719 1 Claim. (01. 242-111) This invention relates to improvements in skein-forming devices and is directed more par ticularly to the provision of improved devices for facilitating the winding up of yarn or the 5 like into the form of skeins. The principal objects of the invention are di rected to the provision of a skein-forming device which is novelly constructed and arranged to form symmetrical skeins of yarn or the like and 10 which is collapsible so as to permit the ready and easy removal of the skeins therefrom. According to special features of the invention, the skein-forming device consists of a novel com bination and arrangement of relatively movable 15 parts and it is simple in form so as to be econom ical to manufacture. As will appear, the arrange ment permits the easy yet efficient manipulation of the skeins. Various other novel features and advantages ‘20 of the invention will be hereinafter more fully referred to after a reading of the following de scription of the present preferred form thereof, and‘ reference will be had to the accompanying drawing, wherein: 5 Fig. 1 is a plan view of the device of the in vention; Fig. 2 is a partial side elevational view of the device shown in Fig. l; and V Fig. 3 is a sectional plan view through one of 39 the cups at a side of the reel. Referring now to the drawing more in detail the invention will be fully described. The device includes a plurality of relatively movable arms which carry on their ends saddles 35 for receiving the yarn and forming the skeins‘. parts, the ?xed arm may consist of a pair of spaced members 4 and 6 and these will have 5 saddle forming parts IS on their outer ends. Preferably I arrange the arm members 4 and 6 ?xed to the shaft so that they are innermost or adjacent one another, as shown, while the ro tatable members 2 and 8 are outside the arms 4 and 6. With this arrangement, there are two 10 cup bearings [2, one ?xed on each‘ end of shaft l0 and outside the outer movable arms-2 and 8. Disposed coil spring in and its 2 as at 22. within at least one of the cups I2 is a 20 which has one end ?xed to shaft other end ?xed to the rotatable arm 15 The spring 20 surrounds the shaft, of course, so that when the arms 2 and 8 are moved counter-clockwise relative to arms 4 and. 6 and from the normal position shown in Fig. 1 the movement is resisted by the spring and when re 20 leased the spring automatically returns arms 2 and 8 to normal position. ' By normal position is meant the crossed po sition shown in Fig. 1. It will be seen that when in use the skein-forming device of this invention , 25 is mounted on its bearing cups for rotation and yarn to be formed into a skein is led thereonto. As the device rotates, the yarn is wound up and caused to traverse the saddles to form the skeins. When these skeins are formed and it is desired 30 to remove them from the device, the rotatable arm members may be moved into a position ad jacent the other arms, thereby facilitating the removal of the skein from the device without straining or in any way injuring the yarn com When a skein has been formed, adjacent arms may be moved relatively closer together so as to decrease the overall perimeter of the device and posing the skein. permit removal of the skein from the device‘. far. To this end, I provide an upstanding stop 40 There is a central shaft l0 and what may be called a journal or bearing cup l2 for the reel. The cup i2 is ?xed to the shaft and is preferably hollow as shown for apurpose which will present 1y appear. 45 I0. Where the rotatable arm mentioned above is formed of a pair of spaced connected-together An arm member or members 2 is rotatably mounted on the shaft and it carries saddles on its opposite ends. In the form shown, I pro vide a pair of spaced arms 2 and 8 which are similarly mounted on the shaft and which are 50 connected at. their outer ends by saddle-forming members I4. Thus, the two arm members 2 and 8 constitute a unit although it is to be understood that a single arm member, suitably rotatable, will suffice. Then I fix another arm member 4 to the shaft 55 It is desirable when the arms return to their said normal position under tension of the spring that the rotatable arm or arms do not rotate too 30 on arm 2 which is adapted to be engaged by a stop 32 provided in bearing cup l2, as shown. While I have described the invention in great detail and with respect to a preferred form there of, it is not desired to be limited thereto since 45 many changes and modi?cations may be made therein without departing from the spirit and scope of the invention. What it is desired to claim and secure by Letters Patent of the United States is: As a new article of manufacture, a skein~ forming device of the class described compris~ ing in combination, a substantially straight uni tary arm member, a shaft ?xed to said arm mem ber substantially centrally thereof whereby por 50 2 2,136,025 tions thereof extend outwardly radially of the shaft in opposite directions, another substan tially straight unitary arm member rotatably mounted on said shaft substantially centrally of the arm member whereby portions thereof ex tend outwardly radially of the shaft in opposite directions, said arm members being normally disposed so that the said outwardly. extending parts of one of them are at right angles to the 10 outwardly extending parts of the other, a bear ing cup ?xedly associated with said shaft, a coil, spring disposed within said cup and around said shaft with its inner end ?xed to said shaft and its other end ?xed to said rotatable arm mem ber whereby the latter is urged to its said normal position but permitted to rotate to a position where all of said outwardly-extending parts are in substantial alignment, and stop means as~ sociated with said rotatable arm member and cup to limit the rotative movements of the said rotatable arm member. 10 1 JAMES P.
