Definitions

  • My invention relates to interlocking slide fasteners and particularly to flexible coverings for concealing the metal members of the fasteners.
  • interlocking slide fasteners i having flexible coverings for concealing the metal members of the fastener are operated by means of sliders which ride over the covering strips;
  • Such fasteners possess the disadvantage that the coverings which are located between the edge l surfaces of the fastener members and the slider, quickly become worn in use. Furthermore when the slider is provided with a locking device which takes the form of a metal prong engaging between the fastener members, this prong usually pierces one or the other of the covering strips when in the locked position and thereby tends to damage same.
  • the principal object of my invention is to provide an improved covered slide fastener, the coverings of which conceal both the members and the slider body, which will be free from the disadvantages enumerated above and at the same time, be of neat appearance.
  • a further object of my invention vis to construct thefasteners and coverings in such a manu ner as to enable' them to be manufactured in a quick,'easy and inexpensive manner.
  • the covering strips are applied in such a manner that the natural side pull on the mounting tape, to which the fastener members are attached, forces the coverings to lie iiat against the metal surfaces of the members thus enabling the abutting edges to be in close contact along the whole length of the fastener.
  • Fig. 1 shows a plan view of a covered fastener
  • Fig. 2 is a cross-section through the fastener showing the fastener members clamped into position on the mounting tape and the coverings partly assembled;
  • Fig. 3 is a cross-section through one half of the fastener showing the next step in the method of assembly;
  • FIG. 4 is a cross-section through the fastener showing the finished coverings
  • Fig'. 5 is a cross-section through the fastener and the operating slider.
  • Fig. 6 is a cross-section through half of the covered ⁇ fastener showing an alternative method of arranging the fastener mounting tape and covering strip.
  • the fastener comprises flexible mounting tapes l, having fastener members 2 attached to their adjacent edges.
  • Each of these fastener members has a pair of legs 3 which are clamped to the tape', and an interlocking end i which is adapted to connect with members of the opposite series in the well-known manner.
  • the operating slider 5 having a pull tab B, is adapted to cause engagement or disengagement of the fastener members as the slider is moved from one end to the other of the fastener.
  • the tape is folded back upon itself as shown in Fig. 2, the lower portion being designated I and the covering strip portion 1. The edge is beaded by folding it over a cord 8.
  • Fig. 3 shows the next step in the manufacture where the covering portion 1 is reversely folded and stitched through the fold to hold the covering portion against the fastener elements.
  • additional side cords 9 are aixed closely adjacent and alongside the rows of fastener members which give the necessary depth to the covering strip to enable it to be built up to a slightly higher level than the top of the fastener members.
  • this cord may be sewn conveniently to the upper and lower parts of the fabric covers 1, during this operation the tape l is folded back into the position shown.
  • any slight tension in this tape in the directionof the arrows A has the effect of causing the covering 1 to lie close to the surface of the fastener members and at the same time cause the two edges of the tape to butt against each other along the whole length of the fastener.
  • the fabric cover strips 1 are preferably made of a material which will have a fair degree of stiffness. For. example, a tightly woven linen or artificial silk may be used. It is desirable to have the strips washed and dried before they are applied so that they will not become more flimsy after they have been applied to the fastener.
  • Fig. 5 shows a Section through' the fastener and the slider 5, illustrating the manner in which the latter rides underneath the covering.
  • the width of covering should 5 be as narrow as possible we make the upper wing l0 of the slider 5 flat, instead of with the usual side anges.
  • yIncases where the covering is required to be of different material from the mounting stringer we use two binding cords, il, ii, 1o as shown in Fig. 6, which are sewn on to the edge l2 of the tape i8 and of the covering Il. which are brought together as shown.
  • the covering is arranged in such a manner that no dimculty is encountered in arranging the locking prong of the slider so that when it is in the locked position the covering strips are not affected thereby. 'Ihe whole of the operating portions of the fastener, with the exception of the pull tab, are concealed by the covering strips and the slider makes metal to metal contact with the fastener members without wearing the covering strips.
  • said covering strips being sumciently stii and said spacer member being sumciently close to said fastener members that the covering strips will normally lie flat against th'e surfaces of the fastener members although having suiiicient flexibility to permit movementv of the slider between the fastener members and covering strips, said mounting strips extending laterally away from the fastener elements beyond the position of the spacer members.
