DONALD PM ZDXYIQWMUQ United States Patent O 3,605,665 INSTALLATION OF SLIDE FASTENERS Florence 0. Donald, 7333 New Hampshire Ave., Apt. 517, Hyattsville, Md. 20783 Filed Sept. 29, 1969, Ser. No. 861,919 Int. Cl. Db 97/10 US. Cl. 112265 3 Claims ABSTRACT OF THE DISCLOSURE A slide fastener is installed by a process wherein meeting fabric panels are temporarily basted to one another and the seam allowances slit to mark the fastener location. Thereafter the seam allowances are doubled at such locations, and the fastener tapes are affixed to the doubled seam allowances. The temporary basting is then removed.

BACKGROUND OF THE INVENTION (1) Field of the invention This invention relates to the installation of slide fas teners in fabric constructions, such as garments, and the like. More particularly, the invention concerns an improved method of installation in which the fastener is rapidly and positively located and wherein the installation is not observable in the normal closed position thereof.

(2) Statement of the prior art Various procedures have heretofore been proposed for the concealed installation of slide fasteners. Among these prior proposals, and representative thereof, are the methods described in the following United States patents:

2,972,751, Leonard et al. 2/28/1961 3,003,445, Crystal /10/1961 3,006,302, McNamara 10/31/1961 3,348,509, Degraw 10/24/1967 These prior proposals have been subject to criticism, both from the standpoint of practicality, and due to the difficulties encountered in the training of beginning students to be trained in the use of both conventional techniques and these prior proposals.

SUMMARY OF THE INVENTION The present invention comprehends a new and novel technique for the installation of concealed slide fasteners which is readily accepted by students and which produces a professional installation with a minimum of training and experience. Moreover, even in the case of experienced persons, the present procedure provides a finished installation of superior and uniform quality.

Adoption of the present procedure substantially reduces the time required to install slide fasteners in garments, upholstery covers, and the like, and reduces machine sewing operations to a minimum in such installations. The invention hereof is employable even with obsolete and inexpensive seWing equipment lacking in special attachments for the installation of zippers.

A further objective of the invention resides in the provision of an installation procedure wherein the use of pins and the like is avoided.

Other and further objects and advantages will become apparent to those skilled in the art from a consideration of the following specification when read in conjunction with the annexed drawings.

FIG. 6 shows the completed installation with the slide fastener partially open;

FIG. 7 is a detailed cross sectional view taken substantially on the section line 7-7 of FIG. 3, looking in the direction of the arrows;

FIG. 8 is a view similar to FIG. 7 showing a next step in the procedure in sectional detail; and

FIG. 9 is a cross sectional view from the attitude of FIGS. 7 and 8 illustrating a completed installation.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to the drawings in more detail, the illustrated environment chosen for illustration of the installation herein relates to fabric elements, such as a garment under construction, in which a slide fastener is to be installed. In the form shown, the slide fastener is to extend fully to an edge of the garment, as for example at the neckline of a dress or the like. At such location, the fabric 10 from which the garment is constructed has two side-by-side panel portions including for purposes of description, a first panel portion 12 and a second panel portion 14. The portion 12 has an inner surface 16 and a outer surface 18, and the portion 14 likewise has an inner surface 20 and outer surface 22.

In FIG. 1, the method of this invention has been instituted to the completion of initial steps comprising the reversion of the meeting edges of the panels 12 and 14 to form seam allowances 24 and 26, respectively thereon. The location of the slide fastener to be installed is then determined. This is best accomplished by placement of the fastener against the previously formed seam allowances. In the installation chosen for illustration, the upper limit of the fastener is of course determined by the edges 28 and 30 of the panel portions (in fastener installations at intermediate locations both upper and lower marking is required in the manner described as follows). The lower extent of the fastener opening is demarcated by the formation of slits 32, 34, as by cutting with scissors, to a depth of substantially one-half the extent of the seam allowances. The seam allowances are temporarily secured to one another along lines 36, 38. This temporary connection is preferably effected by the incorporation of a line of bast stitching 40. Thereafter, each of the seam allowances is pressed into place as by ironing. This places the components in the condition illustrated in FIG. 1.

In FIG. 2, the panels 14 and 16 have been folded about the line of stitching 40 so that the outer surfaces 18 and 22 face one another, this comprising a further step in the within described method. The seam allowance 24 is temporarily flattened outwardly, and is doubled folded to form the double fold section 42, in the direction of the panel surface 16 from the slit 32 to the edge 28 (or the second slit in those instances where required).

The slide fastener per se is generally identified in the drawing by reference numeral 44. The closure assembly comprises a tooth section 46 wherein the teeth are formed of metal, plastic, or the like, and laterally disposed, longitudinally extending flaps or tapes 48, 50, formed of a heavy fabric. The fastener per se is conventional in construction and operation, and includes a slide member 52 actuable to connect or disconnect the teeth responsive to sliding movement from the base catch 54 to the upper limit shown in the drawing.

The fastener 44 is next placed against the doubled seam allowance 42, with the base catch 54 positioned at the slit 32. The orientation of the slide fastener to the panels is shown in FIG. 3, and the corresponding sectional view, FIG. 7. It will therein be observed that the inward edge 46a of the line of teeth 46 is aligned with the edge 56 of the doubled seam allowance 42. In such position, the tape 48 is permanently afiixed to the seam allowance fold by a line of machine stitching 58. The stitches of the line 58, by virtue of the folded back condition of the second panel portion 14 extend through the two folds of the seam allowance 42 and through the tape 48.

Proceeding in the sequence, the second panel 14 is then reverted to its original position, placing the components in the relative positions shown in FIG. 4. Then, sewing from the front side surface 22 of the panel 14, the tape 50 is hand sewn by a hand pick stitch in a line 60. This type of stitching, which is known in the sewing art, produces only a slight exposure of thread, as at 62 in FIG. on the outer or observable side of the garment, while securely connecting the tape by elongated stitches internally, identified at 64 in FIG. 4.

As an alternative, when additional strength is required, the hand pick stitching may be omitted in favor of a machine stitching. This is applied from the back side of the construction, along marking indicia customarily provided on the tape 50. The hand stitch method is preferable from the standpoint of appearance, but machine stitching may be used where sport clothing and the like calls for additional strength.

The foregoing places the components in a disposition shown in FIG. 8. Thereafter, as the terminal step in the method, the basting stitches 38 are removed, resulting in the completed installation of FIG. 9.

The scope of the invention is defined in the appended claims.

I claim:
