' 1 Claim.

This invention relates to men's trousers and particularly to the closure means for the front opening thereof. It has been proposed to provide such openings with a closure of the zipper or slide fastener type in substitution for buttons and button holes. These slide fasteners comprise a pair of stringers, each consisting of a tape having a row of uniformly spaced fastener elements secured thereto and adapted to be in.- terlocked with or disengaged from the elements in the other series by means of a slider member. The'tapes are secured together at one end of the series of elements by a bottom stop which serves two purposes, one to keep the slider from slipping off the interlocking elements and two to maintain the tapes in such position when the fastener is open, that the elements of one tape are always opposite the spaces between the elements of the other tape.

Trousers as ordinarily constructed comprise four main parts, viz, right and left back sections and right and left front sections. It is usual in constructing the garment to stitch together the left back and left front sections to form one half of the garment and to stitch together the right back and right front to form the other half of the garment. Each half is completed with its part of the waist band, pocket openings, and its section of the fiy, andthe various seams pressed before the halves of the. garment are stitched together at thecrotch and back seam.

It is necessary, in the manufacture of the trousers to secure the fastener tapes to the fly at of the garment. As the fastener tapeshaveheretofore been secured together at the factoryjit will readily beapparent that, asconsi'derable finishing of each half of the garment has to take place after the tapes are securedto the fly, the other half of the garment must. be continuously manipulated to keep it .out of the way during the" stitching operation, and further the p'resser foot of the sewing machine has to be raised and low-" ered to permit the slide to be manipulated back and forth-in order to enable the stitching tobe' effected sufficiently close to the fastener elements. It will be apparent therefore that the use of a fastenerof this type complicates. and slows down considerably the manufacture of the garment, and it is the object of my invention therefore to devise a new method of manufacturing the garment which willenable' each half of the gar- 'ment to be completed independently-and while entirely unconnectedwith the other half; the two halves after completion being stitched togetherat the crotch and back scam in a usual way.

Briefly I attain my object by employing two entirely unconnected tapes, each of which has a series of securing elements thereon adapted to be brought into co-operative relationship with those of the other series, and by separately constructing each half of the garment and in the course of said construction securing a separate tape to such half. After each half has been completed, the two halves are stitched together at the'crotc'h and back. The fastener tapes are then brought together and the usual slide member slid over the ends of the series of securing elements. After the slide is in place the tapes are finally secured together below the securing elements, by stitching or otherwise, to prevent accidental disengagement of the slide member.

The invention is hereinafter more specifically described and illustrated in the accompanying drawing in which I Fig. 1 is a perspective view of a pair of trousers with the slide'fastener applied thereto;

Fig. 2 is a front view of the completed halves leg section. 2. Each section ,is first constructed as a'separate unit, as shown in Fig. 2, being subsequently joinedby stitching around the crotch and up the back tothe waist, to. form the complete' garment as shown in Fig. 1-'which also shows the garment provided with the usual opening at the front. 1 It is desired to provide the opening with closure means of the zipper or slide fastener type. I therefore secure to the face of the left, or black, fly in a'tape 3 having along one edge a 'series'of uniformly-spaced fastener'members 5 mounted thereonand to the face of the right, or white, fly la having along one edge a series of fastener members 6 thereon adapted to be engaged with-the members 5. These tapes 3 and 4, it will be noted from Figs. 2 and 3, are entirely unconnected with one another during the con- ]structionof the respective garment sections.

Referring to Fig. 3, it will be seen that the right, or white, flyla: is formed as a separate struction comprising a right leg section i and left piece provided with an inside facing 8. and the I tape 4 is secured between the fly la and the main part I by stitching 8.

As will also be seen from Fig. 3, the front ll of the other part of the garment is formed inthe other edge to the front in, the other tape I is first secured to the face of said fly by stitching I2, one reason for this prestitching of the tape 3 being to avoid having the stitching showon the front of the trousers.

After the parts of the opening have been completed, as well as any other of the usual operations required in finishing up each garment section, the two main sections are then stitched together around thecrotch and up the back seam in the usual manner.

After the garment has been thus completed, the usual slide I4 is mounted on the lower ends of the series of fastener members, the method of application being as shown in Fig. 4 in which the slide is shown mounted on the tape 4 and the tape 3 being threaded therethrough. The lower ends of the said tapes I and i are pref-1 erably left unstitched from the garment to facilihate this threading.

To prevent accidental disengagement of the slide from the fasteners, the tapes immediately adjacent the lower ends of the fasteners are secured together in any suitable manner, such as by stitching I5 of any type but preferably by attaching a bottom stop. The lower ends of the fly will also then be stitched together at 16 in a usual manner.

It will be seen from the above specification that the fastener tapes are entirely unconnected until the garment is complete, thus permitting the carrying on of the stitching, seam pressing and other operations without any interference from the fastener or the other part of the garment, and thus the manufacture of the garment is materially facilitated.

What I claim for my invention is:

The method of constructing trousers having a front opening closed by a slide fastener which consists in taking the separated mating stringers of a slide fastener which comprises a pair of tapes each having a row of fastener members uniformly spaced along its edge, sewing one of said stringers to the face of one of a pair of trouser flies, sewing the other of said stringers to the'face of the other fly and in such position that when the trousers are completed the fastener elements of one tape will be disposed opposite the spaces between the fastener elements of the other tape and with the end elements of each row adjacent one another, sewing one of said flies and its attached stringer to a trouser section, sewing the other of said flies and its attached stringer to a complementary trouser section, joining the trouser sections, threading both fastener tapes through a slider after the trouser sections are Joined together and thereafter permanently'securing the tapes together in such position that the fastener elements of one tape are opposite the spaces between the fastener elements of the other tape by attaching a bottom stop to both tapes adjacent the end fastener element of the series which is adjacent the crotch of the trousers.
