This invention relates to a fly structure for trousers, the general object of the invention being to improve the appearance of the trousers at this point and to enable trousers which are 5 manufactured to sell at low cost to have substantially the same appearance as high priced trousers.

Another object of the invention is to reinforce the trousers at the fly part.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts to be hereinafter fully described, illustrated in the accoinpanying drawings and specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several Views, and 20 in which- Figures 1 and 2 are views of portions of patterns for cutting the cloth for the improved trousers.

"Figure 15 is a view looking toward the inner portion of the buttonhole fly part.

Figure 16 is a perspective view of the exterior 5 part of the button carrying fly part.

In Figure 1 the upper portion of a pattern A is shown for cutting the right hand portion of the improved trousers and in Figure 2 at B is shown the upper portion of a pattern for cutting the 10 left hand portion of the improved trousers. These two patterns are substantially the same and each is formed with a part a having the two notches a in its upper edge and a slot b separating its curved lower edge from the crotch 15 part of the pattern. The right and left front portions of the material from which the garment is to be formed are cut simultaneously from the pattern, the face or right side of the cloths facing each other and the right front 20 portion is shown at R in Figures 3 and 4 and at F in Figure 9 is shown the left front portion of the cut material. Of course the part R is formed with the fly part I which has the two notches 2 in its top edge and the slot 3 at its bottom, the notches 2 being formed in the cloth by the cutter to guide the operator so that the operator will know where to make the creased fold. As these two. notches are cut through all the material the left front part F also has these two notches as shown at 2 but only one of these notches 2' is used by the operator who uses the second notch from the front.

The part I which will be hereinafter referred to as a flap is folded back upon the major portion R on a'line starting at the first notch 2 from the front to the inner end of the slot 3, shown inFigure 2 and then a strip 4 is placed on the folded part I and the parts sewn together as shown at 6' in Figure 5, the line of 40 stitching starting at the second notch 2 from the front. Then the part I is turned back at the line of stitching 6, as shown in Figure 6, so that a pleat I is formed which is increased in thickness by the strip 4 but if the goods are of con- 5 siderable thickness this strip 4 can be omitted. The lining or binding strip 8 is then attached to the free edge of the flap 1, as shown at 9 and the free edge of this binding strip folded upon itself as shown at In and then the strip 8 is folded rearwardly over the flap l to place the folded edge l0 against the rear portion of the pleat 1 after which the parts are stitched together by the ne of st tch n H as shown in F u e 8- In actual practice the binding strip 8 would 5! probably be first sewn to the flap I, then the pleat formed by folding the material and the strip 8 folded rearwardly and the parts sewn together by a single line of stitching to hold the parts in the position shown in Figure 8. Of course, when this is done the seam 6 will not be necessary as the stitching II would hold the parts of the pleat in position as well as hold the folded edge H] of the strip 8 in position.

This forms the button carrying fly part which is connected with the right front portion R of the trousers by the pleat I so that this fly portion has the same appearance as the high priced trousers which is what is termed in the trade as a cut-off fly and this sewn pleat acts to reinforce the trousers at the fly part. The buttons are sewn to the fly part, one of the buttons being shown in dotted lines at I2 with its threads at I3.

The buttonhole fly part I4 first has its free edge folded over as shown at I5 and then is again folded upon itself on a line from the right back notch to the end of slot 3', the fold taking place rearwardly so that the folded left half (buttonhole side) will measure the same as the right half; in other words, by folding back this half inch, it equalizes the half inch that was used up in making the pleat on the button (right) half of the pants; the point is that both sides of the pants are cut one-half inch too large: the button right side one-half inch is used up by the pleat; the buttonhole left side one-half inch is used up by this one-half inch being turned in before the fly is again turned back upon itself from second notch 2 to slot 3. A separate strip I6 in which the buttonholes have already been sewed (buttonhole fly) on which no patent is claimed, is now stitched on to the turned fly and the parts are stitched together by the stitching I9 as shown in Figure 14, it being understood that the folded fly part I4 is covered by the buttonhole strip I6; and this strip I6, known as the buttonhole fly, in which the buttonholes have already been made, is stitched to the part I4 as shown at I9 and 20, so that each buttonhole 2| is separated from the other buttonhole.

It will, of course, be understood that the improved trousers require a small additional amount of goods to take care of the folded part for forming the pleat which gives the appearance or serve the purpose of a cut-off fly used in expensive trousers.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts provided that such changes fall within the scope of the appended claims.

Having described the invention, what is claimed as new is:

1.
