INTERLOCKING SLIDE FAS TENER Filed Sept. 19, 1935 Patented Aug.' i0, 1937 STATES INTERLOCKING SLIDE FAs'rENER Harry Bertram Grant, Birmingham, England, assignor to Hookless Fastener Company, a corporation of Pennsylvania Application September 19, 1933, Serial No. 690,095 In Great Britain December 8, 1932 6 Claims.
My invention relates to interlocking slide fasteners and particularly to flexible coverings for concealing the metal members of the fasteners.
At the present time 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.
An alternative method of covering the fastener has been suggested whereby'thecovering strips conceal both the slider and the members, the slider body in this case operating underneath the coverings. Difficulty is experienced in this construction in making the coverings lie flat on top of the members, in keeping the two abutting edges of the strips .n close contact when the fastener is closed, and in preventing the slider body from appearing bulky beneath the covering.
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.
According to my invention 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.
In the accompanying drawing I have shown for the purpose of illustration, the preferred embodiment of my invention. In this drawing:
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; 5 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; and
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.
Referring to Fig. 1, 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. Preferably 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.
In order that 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. When the tape l is folded into its normal position as shown in'Fig. 4, 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. As it is desirable that 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.
While I have shown and described in this application one embodiment that my invention may assume in practice it will be understood that this embodiment is merely forA the purposes of illustration and description and that various other forms may be devised within the scope of my invention as defined in the appended claims. What I claim as my invention is:
1. In an interlocking slide fastener, a pair of mounting strips, cooperating series of fastener members mounted along the edges of said strips, flexible covering strips attached to the mounting strips and folded back over the sides of said fastening members so that their edges are in abutting contact, and means at the fold tol space the folded portion away from said mounting strips so that it will tend to lie dat against the sides of said fastening members. v
2. In an interlocking slide fastener, a pair of mounting strips, cooperating series of fastener members clamped to the edges of said strips, cover strips one edge of each of which is clamped by said fastener members, said cover strips being folded upon themselves so that each of the other `edges overlies the sides of the fastening members,
aoeaaaa and a series of stitches passing through said fold whereby the folded portion tends to lie against the fastener members.
3. In an interlocking slide fastener, a pair of mounting strips, cooperating series of fastener members clamped to the edges of said strips, a pair of flexible cover strips each having one edge and extending along said mounting strips, and
'clamped by one series of said fastener members folded back upon itself to overlie the sides of said I of the fastener members and each having a k,por-
tion extending to one side of said fastener members over said spacer member, 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.
5. In an interlocking fastener, the combination defined in claim 4 wherein said spacer member is spaced from said fastener members the minimum distance permitting free movement of the slider between said spacer member and fastener members.l
6. The combination dened in claim 4, wherein said cover strips are made` of tightly woven fabric material having sufhcient stiii'ness to maintain the free edges thereof normally against the surfaces of the fastener members.
