STRAND BODIES ' Davis Marinsky and Louis H. Morin, Bronx, N. Y.. Application December 22, 1941, Serial No. 423.934 9 Claims. This invention relates to thread spools or bob bins such as used in connection with‘the shuttles of sewing machines or devices of this type and kind supporting threads, lines, cords and the like. More particularly, the invention relates to the method of treating wound devices of this kind to maintain the strands of the spool llike body against displacement or against accidental or undesirable unwinding, while at the same time, adding lubricating properties to the strand. The novel features of the invention will be best under stood from the following description when taken together with the accompanying drawing in which certain embodiments of the invention are disclosed and in which the separate parts -are designated by suitable reference characters in each of the views, and in which: (Cl. 1124251) for illustrative purposes ’onev adaptation -of the invention. Theillustrations in Figs. 1 and 2 of the drawing are entirely diagrammatic and serve . only to indicate a method of procedure. In these 5 figures, I0 represents a vat or tank containing, forexample. wax or parail‘in as indicated at Il. Anysuitable means, such for example as an elec trie heater l2 will be employed for maintaining -the material I'I in a melted fluid state, the tem -p‘erature being preferably controlled by a ther- l mostat or other control device indicated at l2. In the construction shown, the vat I0 is ar ranged to move vertically in a support i4, the vat being preferably keyed to the support as in dicated at i5.y Projecting centrally from the bot tom of the vat is a plunger I6 having a tooth rack surface il adapted to be engaged by a tooth Fig. l is a diagrammatic sectional view illus wheel I8 arranged upon a suitable- shaft.

' It is the purpose of our present invention to At this time, it will be understood that any provide a wound spool like body. such forex desired number of the spindles 20 may bc ar ample as a bobbin, with means maintaining the strands of the body against accidental displace ment or undesirable unwinding without the ne ranged circumferential-ly of each head‘depending entirelyupon the diameter of the- bobbins or spools 32 mounted thereon with respect to the cessity of using side ñanges or other mediums to size of the heads Il. , retain the strands against lateral displacement. In this connection, it will be also apparent vthat It is the furtherpurpose of our invention to pro instead'of using a single cross beam 22, that a vide a simple, economical and practical manner 50 spider having several arms may be employed, inV of producing products of the kind lunder con sideration, as well as. to provide on the resulting strand removed from the spool or bobbin, lubri cating properties. In the accompanying drawing we have shown which latter event the intermittent rotation of the head and the number of vat stations and ap plicator and ejector stations willy be correspond ingly increased. 'I'he present illustration is sim-. ply to show one possible adaptation of the inven~ _ 2,369,155 '2 tionV and infact individual workpieces 32 may be produced. In our construction itis intended to revolve the entire head at high speeds, while maintaining the spindles 3B relatively station ary. In other adaptations of the invention, means may be provided for individually rotating >the spindles. For purposes of this description, the vat sta tion will be termed the iluidîapplicator station and the other station will be defined as the =eiector and mounting station, >the latter station be ing shown at the right of Fig. 1. The ends of the beam 22 have long bearings 33 land slidably mounted'on these bearings are ejector discs 3d normally held in raised position by a spring 35 seating upon a nut 36. , `Arranged on each head 3l and at opposite sides of the spindles 3o is a pair of ejector pins 37. On these pins are arranged springs 3d which normally support the pins in raised position, and stop pins 39 are employed to limit upward movement of the pins 31. . The heads [email protected] of the pins 3l are normally disposed adjacent the lower A 'surface of the disc 3e vso that upon the depres sion of this disc all of the pins 3l will be moved downwardly and all of the bobbins 32 .simulta neously ejected and dropped upon the tray ‘or pan 29. A plunger di having a forked end ¿it ment and unwinding, particularly the undesir able unwinding which takes place with ordinary threads when used on high speed sewing ma chines. Further the application of the wax or parafïln coating also gives to the thread or . strand a lubricating property which is desirable in the use thereof. In some instances and in processing strands of this type and kind various other materials or compounds may be used other than wax or par añln as herein speciñcally deiined. From this standpoint it will be understood that 'the method t: herein deiined consists primarily in the complete submersion of a wound strand body in a suitable fluid, then in rotating the thread strand body at high speed to throw off all surplus of the mate rial and then to fix the fluid material upon the strands in producing lthe resulting product, It will be apparent that the strand body pro duced according to the method herein defined may be wound in any desired manner and many oi these bodies' have cross windings as int-,he bob bin illustrated. This type of winding maintains the strands against collapse or, displacement. With the present method of coating or impreg nating the strands with the material which es tablishes _a slight adhesion between contacting portions of across _wound strand, the body is further maintained in its wound condition in the cluding the friction discs 21, is adapted te be' 30 absence of retaining discs, whereas a light ten sion pull on the strand will readily unwind the lowered into engagement with the disc ad as in dicated in Fig. 1 and then further depressed in same from the body and yet the strand is kept large enough to span the ends ci the arm 122 in the ejection operation. - trom accidental unwinding. _ After the bobbins have been ejected onto the Having fully described our invention, what we tray or pan 29, the pan is moved out oi aline-‘ 35 claim as new and desire to secure by Letters Pat ment with the lower portion of the head tl and ent, is: ' . a series of untreated bobbins are then applied to ' l.
