- lo would eventuate in the thread sliding over the head of the spool.
With these and other 'objects in view, the invention consists of certain novel features of construction, as will be morefully described, and
15 particularly pointed out in the appended claims.
In the accompanying drawing: Fig. 1 is an elevation showing a spool with thread wound thereon;
Fig. 2 is a sectional view with the thread omitted;
Fig. 3 is a sectional view showing the two parts of the spool;
Fig. 4 is the sectional line Ii-S of Fig. 2; Fig. 5 is a sectional view of a modified form 25 of a spool; Fig. 6 is a diierent form of modification;
Fig. 7 is an elevation of the spool showing the grain in the wood of the two diierent pieces; and Fig. 8 is a sectional view showing a different so modication. Y
Spools having single heads are in many 1nstances formed with a conical head so that the package of thread on the spool may have a conical formation which will retain itself in position g5 Without the necessity of providing a second head. Such spools are usually operated with their axis vertical (although in some instances this axis may run in a horizontal position). When a spool operates with its axis vertical on a sewing machine, o or the like, the vibration or jiggling o f the sewing machine will cause the spool to vibrate and lift on its axis. The thread on the spool will frequently, when a bit of slack occurs, slide down the vertical outer surface of the package and 45 conical surface of the head and lodge beneath the spool and there become caught so that the pull on the thread will cause the thread to break.`
This is a very real dificulty encountered in the operation of machines using this type of spool. 50 Various manners and various attempts have been made to solve the problem. I have, however, approached the problem differently than previous attempts in an eiort to solve the same and have, in avery simple manner, changed the spool itself 55 so that rather than trying to prevent the thread from movement toward the head, I catch'the thread after it has slid down and support it so it cannot get below the spool or in any crevices .to catch and be broken, and this I accomplish bv providing a flange on the head of the spool which 5 will present a surface either in a plane at right angles to the aids or will incline inwardly so that any thread which drops on this flange will be supported and cannot get below the spool; and
the following is a more detailed description of m thepresent embodiment of this invention, illustrating the preferred means by which these advantageous results may be accomplished:
With reference to the drawing, IIJ designates a shank of the spool and I I the head thereof. This head consists of conical portion I2 presenting an inclined surface I3 to shape the package of thread It which may be wound thereon. I form on the heady Il a flange I5 which extends outwardly, radially, from the shank of the spool. This flange presents its shank-side surface either at right angles to the axis of the spool asshown at I6 in Fig. 5 or inclined inwardly as shown at I6 in Figs. 1, 2, 3 and 6, and by the provision of this flange I5 and this supporting surface I6 and g5 I6', any thread Il which may drop from the package IB will be caught and supported by this surface I6 and I6 and prevented from spilling by sliding beneath the head of the spooland there becoming caught and broken. so
While I may form the parts which I have just mentioned all in one piece as shown in Fig. 6, it is usual that when the spool is turned from wood with the grain running generally axially of the shank, that chipping of the flange is liable to 'occur during the shipping or rough handling and, accordingly, I preferably form the shank It in one piece as illustrated in Fig. 3 and the head in another piece` I I in Fig. 3 with the grain of the wood in the shank running axially of the' shank and the grain of the wood in the heafl running at right angles to the axis of the shank and in this manner chipping of the flange is very much reduced. It may be, however, that where the material used is not of the grain characteristics of wood that a single-piece product will be satisfactory.
In Fig. 8 I have illustrated the shank I@ and conical head II as formed al1 in one piece as is a usual construction and have provided an additional piece I9 secured to the under surface of the head by cement I 8 which piece may be of some material different than the wood ofthe shank and head and may, for example, be fibre or cardboard. Inshipping, however, spools provided with a cardboard member to form a flange have not proven satisfactory from the standpoint ot withstanding rough handling, although from the standpoint of operation of the invention, if the portion IS be not damaged the member I 8 may exist in cardboard as Well as other materials, provided the joint 2l may be made to prevent the occurringgof a crevice which is an added factor to guard against in a construction so formed and which is not present at 20 in Fig. 5 or -the other figures heretofore described.
'I'he foregoing description is directed solely towards the construction illustrated, but I desire it to be understood that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being de ned and limited only by the terms of the appended claim.
20 A cemcal end yarn package comprising a cylindrical winding of yarn about a single-headed spool having an individual shank portion with an adjoining individual conical head portion provided with a relatively short taper abruptly increasing in diameter from its juncture with the shank portion and extending throughout the diameter of the Winding of yarn, said head portion being provided at the termination of its taper with a ange extending outwardly beyond said winding o! yarn, said flange having a surface on the shank side thereof so formed and. arranged 4as to prevent the movement of yarn on the outer of the shank to minimize splitting of said ilange.
