4 Claims.
My present invention relates to separable fasteners and has particular reference to a novel construction of slide fastener.
The principal object of the present invention is to provide a slide fastener in which the coupling links are covered on both sides of the tape so as to provide a neat and finished appearance and to prevent catching of hairs, threads, or cloth between the links during the operation of the fastener.
Another object of the present invention is to provide a slide fastener having covered couplin links in which the covering elements are integral with the tape.
A further object of the present invention is to provide a novel type of integral tape construction for a slide fastener which provides a cover for the coupling links and for the slide.
A further object of the present invention is to provide a novel covered slide fastener which is simple in construction and easy and economical to manufacture.
With the above and other objects and advantageous features in view, my invention consists of a novel arrangement of parts more fully disclosed in the detailed description following, in conjunction with the accompanying drawings, and more specifically defined in the appended claims.
In the drawings:
Fig. 1 is a front elevation of a portion of a slide fastener embodying my invention;
Fig. 2 is a rear elevation thereof;
Fig. 3 is a section taken on line 3-3 on Fig. 1;
Fig. 4 is a plan view of a stringer cord;
Fig. 5 is a similar view with the coupling links attached thereto;
Figs. 6, 7, 8 and 9 are diagrammatic views showing one method of assembly;
Figs. 10, 11 and 12 are similar views showing another method of assembly;
Fig. 13 is a front elevation of a modified construction of my invention;
Fig. 14 is a section taken on line l4l4 on Fi 13.
Fig. 15 is a similar view of another form of my invention; and
Fig. 16 is a section similar to Fig. 3, showing the slide outside the covering tape.
Referring to Figs. 1 to 3, inclusive, my novel slide fastener 20 comprises a pair of textile fabric attaching tapes 2| and 22 of identical construction and adapted to be sewed or secured to opposite edges of an opening in the conventional manner. Each tape 2 I, 22 comprises a main body portion 23 diverging at one edge thereof to form integral laterally extending cover portions 24 and 25. A flexible cord 26 of large diameter forms a slide fastener link carrier and is incorporated in the tape as an integral portion thereof, be-
tween the cover portions 24 and 25 at the crotch or inner juncture 21 of the bifurcated edge formed by the two longitudinally extending cover portions. I
Coupling links 28 are fastened to the cord portion 26 at uniformly spaced intervals in the conventional manner. In the form illustrated in Figs. 1 to 3 inclusive, the cover portions 24 and 25 are just long enough to extend over to the central portion of the working zone of the links 28 so that in closed position, the edges of the cover portions 24- and 25 on the tapes 2! and 22 meet and thus cover and conceal the interlocking links 28. The resultant fastener gives a more pleasing and uniform appearance, the metal being concealed, prevents contact of the metal with the skin of the wearer, and prevents snagging of hairs or fabric when the slide is operated.
While any standard type of slide may be used to operate the coupling links 28, I prefer to use a slide 29 having its front and rear portions sliding directly on the metallic couplings and being at least partially concealed by the overlying cover portions. The slide 29 is preferably of a minimum width and the rear portion 30 is preferably tapered, so that the slide will readily travel beneath the cover portions 24 and 25 without spreading the same. Furthermore, by sliding the slide 29 beneath the cover portions, the danger of snagging or catching of adjacent surfaces in the slide is eliminated, and wear or fraying of the material by the slide is avoided. It should further be noted that the cover portions 24 and 25, although integral with the main body of the tape 23, are of comparatively narrow width because they extend only from the cord 26 to the center of the links 28. This permits the tape to be made in the standard widths and reduces the cost of manufacture.
One method of assembling the fastener is illustrated in Figs. 4 to 9, inclusive. A suitable flexible cord 26 is passed through a conventional link attaching machine (not shown) which fixes the spaced coupling links 28 to the cord 26 as shown in Fig. 5. The cord 26, hearing the links 28, is then passed into a conventional tape weaving loom (not shown), the cord 26 forming one of the warp or lengthwise threads. A single or double weft thread may be employed in the weaving operation, diagrammatically illustrated in Figs, 6 to 9. In the first pick cycle the weft 3i passes across the width of the body portion 23 and cover portion 24 and then back again, incidentally interlocking with the warp threads but not with the cord 26, see Fig. 6. The weft 3| then again passes the width of the portion 23, around the cord 26, to the end of the cover portion 25, back around the inside of the cord 26 to the end of the cover portion 24, then again back to the end of the cover portion 25, and then back to the end of the body portion 23, see Fig. '7. The third pick cycle, see Fig. 8, is the same as the first, the weft passing to the end of the portion 24 and back. In the fourth and finalcycle, Fig. 9, the weft 3| passes along the portion 23, around the cord 26 to the end of the cover portion 25, back to the cord 26, again back to the end of the portion 25, then back to the beginning of the portion 23. These four cyles are continuously repeated and result in a tape 2| in which the portion 23 and cover 25 have the same number of threads and the portion 24 has two threads less. The cord 26 becomes integrally woven into the tape at the point of divergence of the two cover portions 24 and 25. However, it should be noted that the weft 3| binds the cord 23 to the tape only at alternate cycles, Figs. '7 and 9, leaving evenly spaced open lengths of the cord 23 exposed. This adds materially to the flexibility of the final tape and avoids the stiffness normally resulting from weaving a cord within the tape. Furthermore, the coupling links 23 are positioned in the exposed cord area and therefore do not interfere with the weaving operation. By this method, my novel tape can be made in the same number of operations as the conventional tape 1. e., stringing the coupling links and weaving the tape.
If desired, the alternative method shown in Figs. to 12, inclusive, may be used. In this method, the tape 2| is woven with the cord 26 as hereinabove described, but without the attached coupling links 28. This results in the structure shown in Fig, 10. The cover portions 24 and are then folded back towards the portion 23, see Fig. 11, and passed through a conventional coupling link attaching machine in this position. A suitable guide may be positioned onthe machine to retain the covers in folded position. The links 23 are thereby attached to the cord 26, see Fig. 12, preferably, but not necessarily, to the open exposed alternate surfaces of the cord resulting from the weaving operation. The resultant tape being identical with that of the method hereinabove described, as shown in Fig. 3.
If it is desired to completely cover the coupling links 23 in both open and closed positions and to guard against any posibility of snagging, the fastener 33, illustrated in Figs. 13 and: I4 may be used. In this form the rear cover portions 34 are made longer than the front cover portions 35,
and of sufllcient length to cover the coupling 7 links in open position. With the tape closed, the front cover portions 35 will lie edge to edge as in the previous forms, whereas the rear cover portions 34 will overlap and completely cover the links and the rear of the slide.
Further, if desired, the fastener may be constructed as shown in Fig. 15, in which both the front cover portions 36 and rear cover portions 31 are made to overlap.
While it is preferred to have the slider operate beneath the cover portions, the construction shown in Fig. 16 may be utilized, if desired. In this form the slider 33 is placed on the outside of the cover portions 39 and 43. It should be noted that the cover portions of the present invention are of comparatively narrow width and begin directly at the cord, so-that when the slide is placed on the outside, the cover portions are completely under the slide and the side edges of the slide pass over only the single thicknes of the material of the body portion. This form may be varied by placing either the front or rear portions of the slide under the cover portions, as in the previous forms, one side of the slide being covered and the other side exposed.
The fastener of the present invention is thus simple in construction and easy and economical to manufacture and assemble. Since the coupling links are completely covered, clothing manufacturers can have the tapes woven out of the same material as the dress or suit into which the fastener is sewedwithout additional expense. simultaneously with the weaving of the original cloth.
Other objects and advantageous features of the present invention will be obvious to a person skilled in the art to which the present invention relates,
While I have described certain specific embodiments of my invention and certain specific methods of manufacture of the same, it is obvious that changes in the size, shape and relative arrangement of the parts, may be made to suit different requirements without departing from the spirit and scope of the invention as defined in the appended claims.
