WAHL (Ittorneg Patented Feb. 26, 1952 SEPARABLE FASTENER ASSEMBLY Nicholas A. Wahl, New York, N. Y., assignor to Wahl Brothers, New York, N. Y., a partnership Application July 21, 1948, Serial No. 39,849
  • This invention relates to a separable fastener, particularly to a separable fastener, and to a tape useful therein, fashioned in such a way as to provide a track or bead for guiding a slider used for separably joining and for releasing the string! ers of the fastener.
  • a number of types of separable fasteners have been devised and used widely.
  • One type comprises, broadly, a row of individual links or engaging elements secured at regular intervals on a runner, such as a cord, which maintains regular spacing of the engaging elements, each link having hooks and eyes or other means to separably engage the eyes and hooks, respectively, of a similar row of links secured to another runner.
  • the links and runner are assembled in a tape to form the conventional link stringer and 'the tape can .then be sewn, or otherwise secured,
  • links can be secured directly to the edge of the tape.
  • a number of ways have been devised for securing individual links to a cord in accurately spaced alignment, one way consisting in fashioning the root of each individual link, i. e., the end of the link removed from the end provided with a hook and eye, in the form of a split ring so that it may be clamped onto a cord longitudinally positioned with respect to the rows of links.
  • a number of ways have been devised for assembling a runner carrying a, row of such links in a tape.
  • separable fastener comprising, broadly, a coil stringer consistin of a row of filament loops, which constitute the engaging elements, secured in spaced relationship longitudinally along a tape and adapted to nestle within and engage in positive interlocking fashion a row of similar, but oppositely wound, filament loops secured longitudinally along another tape.
  • the tapes having the rows of filament loops assembled therein may be sewn or otherwise secured to pieces of fabric or other goods which it is desired to separably join.
  • the filament loops just described may be prepared conveniently from a wire or plastic filament in the form of an elongated continuous coil, usually of approximately helicoidal form.
  • One segment of each loop of the coil then serves as an engaging element to engage the loops of a similar, but oppositely wound, coil and the segment of a loop which lies between and joins two such engaging elements serves as a short. flexible runner to maintain spacing of the two engaging elements.
  • the cooperating action of the runner and the tape serves effectively to keep the engaging elements in fixed spaced relationship.
  • each loop of the coil deformed slightly so that the separate loops are each somewhat noncircular, e. g., ovoid or eliptical, in appearance when viewed in the direction of the longitudinal axis of the coil.
  • each woof thread, or cross thread passes between the forward edges of two adjoining convolutions or loops of the coil and engages and lies across the inside of the rearward section of a loop.
  • the marginal sections of the tape having both warp and woof threads, are folded together and then usually sewn or otherwise joined along aline adjacent the coil. In this way, the woof threads anchor the tape to the coil.
  • An additional object is to provide a separable fastener having a coil Or link stringer in which a stringer is not subject to disengagement from the slider while the stringers are being separably joined
  • An additional object is to provide a separable fastener wherein the engaging elements are substantiallycoveredand hidden from view when the stringers are separably joined.
  • An additional object is to provide a tape for a separable fastener of novel and improved design.
  • An additional object is to provide a method for simultantouslyforming a tape for a separable fastener andsecuring astringer thereto.
  • a longitudinal section of the tape wi11 provide continuous track or'bead lying snugly against the row-of elements along a line substantially opposite the engaging segments of the elements and another longitudinal section of the tape will lie along asideof the elements between the en.- gagingsegrnents-thereof and the track to coven. substantially all of the surface of one side of.each.. of the elements which would normally ,beexposed towiew when-the fastener is separably joined.
  • the tape is secured firmlyto the row of elements.
  • Figure 1 is a perspective, partlycut away, ofv a stringer tape for a separable fastener embodyingfeatures of the invention
  • Figure 2 is a plan view of one side of a separable fastener comprising a slider and a pair of assemblies of-the invention.
  • Figure 3 is a plan view of a section of. a separable fastener assembly similar to those of Figure 2, but viewed from the reverse side,
  • Figure 4 is a-view, partly in plan, takenalongthe line IVIV of Figure -2, but with certain .ele. ments omitted for purposes of illustration,
  • Figure 5 is a view, partly in plan, taken along the line v v of Figure 2,
  • Figure 6 is an end elevation, partly in plan and partly in section, of a separable fastener assembly of the invention shown at an intermediate step in its formation
  • Figure '7 is a view, partly in plan, taken along the lines VII--VII of Figure 6,
  • Figure 8 is an end elevation, partly in section, similar to, the view of Figure 5, but showin engaging elements consisting of individual interlocking links instead of loops of a pair of coils.
  • a stringer tape of the invention consisting of a fiat fillet or ribbon II of fabric or other suitable material and. a cord I2 longitudinally parallel therewith and. ata distance removed therefrom,
  • the distance by which the cord I2 and the ribbon II are separated from one another when the tie threads I3 and I are taut will vary depending upon the particular type and size of the engaging elements'which are to be assembled in the tape as will be apparent upon further reading of the description.
  • the cord I2 can be of any suitable construction and can conveniently be a simple twisted cord of from-2 to 20 or more strands.
  • reference numeral I2 in each of the figures refers to the entire cord and not specifically to any single strand thereof.
  • the size of the cord used will depend to some extent on the type and size of the engaging elements used in making the assembly and also upon the type and size of the slider used forjoining and separating the assemblies of the invention.
  • Any convenient fillet or ribbon I I can be used,"preferably a fabric ribbon woven in such fashion that'it is not subject to undue distortion when stressed.
  • the tie threads are secured to the ribbon II along a line parallel with and at a slight distance from one edge of the ribbon.
  • the distance separating the edge of the ribbon and the line of attachment-of the tie threads to the ribbon should be such that when the engaging elements are assembled in the tape the portion of the ribbon II 'lyingbetween its edge and the tie threads, herein'referred to as the marginal portion or section of the'ribbon or tape, is of appropriate width, as is shown more clearly in Figures 4, 5 and'8j'to provide a covering for one side of the row of elements when the fastener is separably joined, but it should not be wide enough to more than abut the corresponding marginal section of the ribbon of'the tape of the cooperating assembly to prevent crowding and buckling of the marginal sections of the tapes.
  • a coil Ii! suitable for use in a separable fastener is positioned longitudinally parallel with and insubstantial contact with one side of a ribbon II with the transverse axes of the coil which are perpendicular to the ribbon intersecting the ribbon along a line parallel with and removed "somewhat from one edge of the ribbon and withithe segments of the convolutions or turns of' the coil which are adapted to engage corresponding segments of a complementary coil facing the edge of the ribbon.
  • a cord !2 is then positioned parallel with the coil and ribbon and on the side of the coil opposite the ribbon II so that the transverse axes of the coil previously referred to intersect the cord substantially along its longitudinal axis.
  • the cord and ribbon are then sewn together with tie threads I3 and I4 using any convenient or conventionalstitch so that the tie threads lie substantially along the same transverse axes previously referred to, the coil serving as a spacer or form to maintain proper spacing of the cord and ribbon.
  • One type of suitable stitch is shown in Figures 4, 5, 6 and 7 and another in Figure 1.
  • each turn of the coil which is opposite the engaging segment, and which is indicated in the drawing by the reference numeral I9, e. g. of Figure 6, is designated herein as the rearward segment of the turn and the'engaging segment 29, is referred to as the forward segment.
  • Each individual loop 'of the coil is considered to consist of a portion of the coil filament starting at or near a rearward segment I9 and following along the filament until the next adjacent rearward segment is reached.
  • Each loop thus includes two opposite side segments of one turn of the coil and the engaging segment between the two side segments.
  • Each rearward segment I9 serves to join one loop of the coil to an adjacent loop.
  • the row of rearward segments is herein considered to constitute a discontinuous runner which holds lithe row of loops together in proper spacing and alignment and which corresponds to the conventional continuous runner cord of the individuallink type of fastener.
  • the separate loops or engaging elements of the coil are thus separated from one another at the forward or engaging edge of the coil but are joined together by the runner segments I9 at the rearward edge of the coil.
  • the tie threads thus can, if desired, be disengaged from the coil by moving the coil from the position as shown in Figure 6 in a rearward direction and the coil and tape thus completely separated.
  • a coil fastener can be mounted or assembled in the tape by moving the coil in a forward direction between the cord I2 and the ribbon II so that the threads pass between the separate loops of the coil.
  • the assembly is completed, after the tie threads I3 and I4 have been inserted by sewing as shown in Figure 6, by sliding the cord I2 around the outer circumference of the row of loops in a direction rearwardly of the loops until the cord lies in contact with the ribbon II and with the rearward or runner segments I9 of the turns of the coil.
  • the relationship of the parts at this point is shown clearly at the left hand side of Figure 4 wherein the strands of the cord I2 are shown occupying the angle between the ribbon II and the rearward segments I9 of the coil.
  • the tie threads I3 and I4 engage and lie over the rearward or runner sections I9 of the coil and hold the ribbon I I and the cord I2 firmly against each other and against the coil.
  • the assembly is sewn longitudinally with a binding thread on a line between the cord and the coil.
  • binding threads I5 and IS pass through the ribbon II and over the tie thread and thus anchor the entire assembly firmly together.
  • the binding threads I5 and Hi can be inserted using any suitable or convenient type of stitch and also that, if desired, the binding threads can extend not only over the tie thread but can be inserted so as to extend directly through the cord I2.
  • the cord I2 can comprise either a substantially round multi-strand twisted structure or a narrow flat ribbon or any other relatively narrow continuous element suitable for forming a track for the slider and the term cord is herein used is intended to include such elements.
  • the cords I2 lie between the rearward segments IQ of the individual turns of the coil and the projecting portions 2I of the slider 22 filling substantially all of the space therebetween and providing a firmly secured track along which the slider can move and which serves eifectively to prevent entry of the projecting portions of the slider betweenthe individual turns of the coil.
  • Figure 8 illustrates an assembly of engaging units, consisting of individual links 23 mounted on a conventional runner cord 24, a tape similar to that of Figure I and appropriate tie threads I3 and I4 and binding threads I5 and I6.
  • a tie thread I3 extends from the ribbon II between the individual links, over the runner cord 24 and thence through the cord I2.
  • Binding threads I5 and I6 serve to secure the ribbon, the stringer and the cord firmly together in a fashion identical with that described in connection with the coil stringer.
  • Cooperation of the two separable fastener assemblies just described with the slider 22 is similar in every respect to the case of a coil fastener previously described.
  • a tape for a separable fastener comprising a flat ribbon, a cord longitudinally parallel with the ribbon and spaced substantially therefrom, and tie threads secured to and extending between the cord and the ribbon and joining the ribbon in a single line parallel with and substantially removed from one edge of the ribbon.
  • a tape for a separable fastener comprising a fabric ribbon, a cord longitudinally parallel with the ribbon, and tie threads secured to and extending between the cord and a single line in the ribbon parallel with and removed from an edge of the ribbon to secure the cord in spaced parallel relationship to the ribbon.
  • a separable fastener including: a row of engaging elements secured at regular intervals along a runner; a ribbon parallel with the runner and comprising a marginal section extending at least partially along one side of the engaging elements; a cord parallel with the runner and in contact with the ribbon and the segments of the engaging elements opposite the engaging segments thereof; tie threads extending between the inner edge of the marginal section of the ribbon and the cord and passing between the engaging elements on one side of the runner; and binding threads binding the cord and tie threadsthearibbon infirm contact therewith and with; the engaging elements 7 on the other side of the runner,
  • the method for making a separable fastener assembly which includes: disposing a stringer comprising engaging elements secured at regular intervals along a runner, a cord and a ribbon in parallel longitudinal relationship and so arrangedthat oneside of each engaging element is in contact with one side of the ribbon along a line parallel with and substantially removed from one edge of the ribbon with the engaging segments of the engagingelements facing the said edge of the ribbon, and the other side of each engaging element is .in contact with the cord; and sewing through the cord and ribbon between the engaging elements on one side of the runner to tie the cord and ribbon together.
