8 Claims, 9 Drawing Figures PATENTEBMM m2 3,706,103 sum 1 or 2 l N VE N TOP PATENTED DEC 19 m2 SHEET 2 BF 2 BRIEF AND METHOD OF PRODUCTION BACKGROUND OF THE INVENTION The aforesaid prior invention involves a brief, or snugly fitting drawers, characterized by the presence of an overlap extending upwardly from the crotch and overlapping a panel which extends downwardly from the waist'over the abdomen, and including a passage with a horizontal opening, the upper edge of said overlap having means for resiliently closing said passage.

That structure has certain important advantages not found in the prior art.

The usual brief, as marketed for a long time, is characterized by overlapping layers of fabric in front with an opening along a vertical line. Furthermore, such a garment is usually fabricated from a plurality of pieces or swatches of fabric, as-many as six in some cases, requiring considerable hand labor in cutting and sewing and excessive waste material. Hence, the cost is high.

BRIEF OUTLINE OF THE INVENTION The present invention, in contradistinction to said U.S. Pat. No. 3,487,833, is characterized by the presence of a pair of overlapping flaps of fabric covering the abdomen, groin and crotch portions of the wearers anatomy and providing a horizontal passage through the vertical edges of said flaps. The structure of said garment is so designed and constructed that said vertical side edges of the aforesaid flaps providing said passage will permit manual access from the right side and will normally be maintained taut. Thus, the overlap which forms the support will provide thesupport for the genitalia desired by young males who prefer this type of garment.

Another object is to provide a garment of the type referred to so designed that it may be cut fromtubular fabric in such manner as to provide little or no wasted material, thus reducing cost.

Still another object is to provide a garment of the type referred to designed so that it may be cut from tubular material to provide a swatch which may, if desired, be attached to the garment as a seat reinforcement.

A further object is to provide a new and improved method of producing a garment of the type referred to which may be fabricated from 'a single blank of fabric, with a minimum of cutting and sewing operations, and thus is simple, economical, and capable of operation by relatively unskilled labor,

Other objects and advantages will doubtless suggest themselves to those skilled in the art as the description proceeds.

DETAILED DESCRIPTION conveyor or the like. Such material has a one-way elasticity as indicated by arrows in FIGS. 8 and 9. Obviously, such a tube will provide a pair of overlapping sheets I2, 12' of identical width, with longitudinal edges or fold lines F and F.

A rectangular section is cut from the tubing as defined by the

transverse line

15, 15.

A cut is made through the tube material through both tubing layers 12 and 12' of generally triangular shape, as indicated by numerals 20 and 23, said cut producing a swatch 25 seat patch of generally triangular shape which then is removed as'shown in FIG. 9. The converging sides of the triangle may, but need not necessarily, terminate a short distance inwardly of edge F.

The tube is then cut along fold line F, and the section then opened along fold line F resulting in a substantially rectangular swatch as seen in FIG. 7, with the triangular spaces disposed in allochiral relation. Further cutting is then done along the

lines

16, 16, I8, and 18', resulting in two identical blanks B (FIGS. 7 and 8), capable of producing two garments.

The rectangular swatch defined by lines'l8, 18, 20, 20' is eliminated, being the only waste resulting from the operation, which is of negligible economic importance.

Blank B is yoke-shaped and characterized by a substantially straight horizontal edge 30 which is of a length sufficient to pass around the wearer's waist, with a substantial overlap, as seen in FIG. 1. Depending from edge 30 at opposite ends thereof is a pair of

flaps

32, 32 defined by vertical

outer edges

33, 33 and

inner edges

35, 35 which are roughly parallel to

edges

33, 33, but slope upwardly and inwardly to

rounded corners

37, 37 and thence extend diagonally downwardly and inwardly at an angle of about 45 along

straight lines

40, 40, the lower ends of which are spacedapart to define a relatively short horizontal edge 42, approxi mately equal in width to the wearers crotch.

It will be seen that the central portion 41 of blank B is roughly triangular, corresponding approximately to the shape and size of swatch 25 (FIG. 9).

, As stated hereinabove, the fabric of which tube is formed is essentially a one-way-stretch material and the blanks hereinabove described are cut so that the major stretch thereof is in a horizontal direction, as indicated by the arrows in FIGS. 8 and 9'.

Blank B constitutes substantially the entire fabric of the garmentembodying my invention, except for a few accessories such as a waistband 45 (FIG. 8) and elastic edging material hereinafter described.

One of the features of the present invention is the use of a continuous unitary tape binding T which is stitched to all of the edges of the blank B below the horizontal edge 30. Thus, referring to FIG. 8, the sewing machine operator would begin by attaching the tape binding T at the upper right hand corner indicated by the letter X and wouldjstitch the binding T successively to

edges

33, 32, 35, 37, 40, 42, 40, 37, 35, 32' and 33 and ending up at the left hand corner Y directly opposite the starting position X. At this point all of the edges of the blank B, except edge 30, are covered by the tape binding T.

This construction affords substantial advantages in the fabrication of the garment. The use. of a unitary piece of tape binding covering all of the edges below the waistline simplifies fabrication, permitting the employment of operators having lower degrees of skill than heretofore required in the industry for similar functions. Further, avoidance of the use of a plurality of shorter tape binding sections, as in the prior art, results in an increased rate of production of the gar ments.

To complete the fabrication of the garment, Blank B is folded over upon its vertical median line, M resulting in overlapping

flap portions

32, 32, as seen in FIGS. ,1, 3 and 4. The elastic waistband 45 may then be attached by stitching 47 and the lower edges of flaps 32, in overlapped relation, are then secured to the lower edge 42 of the central portion 41 by a horizontal line of zig-zag stitching 48 (FIG. 3) passing through edge binding T.

Flaps

32, 32 are likewise secured together by stitching 38, 38 at the top and 34, 34 at the bottom for stabilization. Such stitching extends only a relatively short distance from the top and bottom, respectively, leaving a free open space therebetween for convenient access. Such access may be had from the right side.

Obviously, in production, the length of the slit or opening between the top and bottom vertical stitching may be adjusted as desired by varying the length of said stitching.

Because of the double folds of

fabric

32, 32 forming overlap P, this structure provides superior support for the male genitalia, which is a feature of considerable importance in this type of garment.

Furthermore, my improved structure insures, in addition to the excellent support just mentioned, that firm and neat closure is provided at all times, the double-' walled overlap providing comfortably positive coverage of the groin and abdomen, at the same time permitting ready ingress and egress through the passage between the flaps.

Although the garment is complete in all respects as hereinabove described, inasmuch as my invention provides the swatch 25 precisely the desired shape and size to form a supplemental seat portion, it is so employed by stitching said swatch 25 to the back of the garment, as seen in FIGS. 2, 3 and 5, the stitching extending around the periphery of said swatch. Thus, my invention permits reinforcement of the garment in the seat, a place of maximum wear, at substantially no added expense.

It will be seen that I have conceived a novel form of brief having a number of superior features, as well as a novel method of production thereof, resulting in nearly a up to six, effects a saving in both labor and material,

while production of the supplemental seat reinforcing swatch requires no extra step of labor except for its attachmdnt.

Various changes coming within the spirit of my invention may suggest themselves to those skilled in the art; hence, I do not wish to be limited to the specific embodiment shown and described or uses mentioned, but intend the same to be merely exemplary, the scope of my invention being limited only be the appended claims.
