22 Claims.

'I'his invention relates to knitted breast pockets adapted to be incorporated in brassires and other garments for women and produced each from a single strip of seamless knit fabric which is soi formed and fashioned during the knitting process as to give a predetermined cup-shaped contour to the nished pocket.

One of the main objects Aof the invention is to provide a one-piece knitted breast pocket so constituted as to vary in curvature and diameter in different circumferential areas in such manner as to give a breast a neat molded appearance.

Another object of the invention is to form a one-piece knitted breast pocket so as'to have an elongated, generally oval cross-Section, and to attain such shape through suitable fashioning of the breast pocket fabric during the course of knitting the same.

Still another object ofthe invention is to form a breast pocket of a seamless knitted fabric strip constituted of a group of fashioned sections knit A DQ Cil

one after the other which sections are so formed `and arranged that in the completed pocket the distance between the center and the edge of .the pocket will vary in different circumferential areas.

Another object of the invention is to form a fashioned breast pocket as a plurality of integral successivelyknit triangular sections, the form of different sections being varied so that the pocket has different diameters in vertical and horizontal directions.

A further object of the invention involves the production Voi a fashioned one-piece knitted breast pocket wherein the knitted wales in both the upper and lower portions thereof run in the same general direction, preferably horizontally, thedirection of stretch of the knitted fabricbeing more or less the same in the several portions.

It is further proposed to vary the degree of stretch in the upper and lower portions of the pocket so that, entirely aside from the direction of stretch in different areas, the pocket will be less yielding and exert a firmer molding effect on the breast in the area which requires the greatest support.

It is a still further object of the invention to provide a process of forming a fashioned breast pocket blank as a single strip of seamless knit fabric according to which the desired shaping of the pocket is obtained,'and which, furthermore, is so simple as to readily lend itself to mass production of fashioned knitted breast pockets. The proposed knitting process may be carried out on a conventional type of knitting (c1. ca -176) machine and may be continuous in the sense that fashioned blanks for a series of breast pockets may be knit without interruption as a single long strip of fabric from which the individual blanks can be subsequently severed. v i

The above and other objects and features of the invention will become more apparent from the accompanying drawing and specification taken in connection withthe appended claims.

In the drawing: i

Fig. 2 is a front elevation of the completed breast pocket as made from the blank ,of Fig. l;

Fig. 3 is a side elevation corresponding to Fig. 2;

Fig. 4 is a bottom plan view; and

Fig. 5 illustrates breast pockets according to the invention embodied in a brassire.

The invention involves the knitting of a fabric blank as a succession of knitted courses and the fashioning of such blankby narrowing and widening in various courses in such manner that the breast pocket formed from the blank will suitably mold the breast. VThe blank is formed as a series of successively knit fashioned sections of substantially triangular form, each section being knit integrally with a preceding section and joined thereto along a fashioning line. One section m'ust Vbe made relatively long in a walewise direction to give the desired oval shape to the pocket. The remainder of the blank may be 1.,

made of smaller sections of shorter length.`

Referring to Figs. 1 and 2, the pocket is here shown in a simple form comprising three triangular sections b, c and d, the same being so proportioned and shaped that the long triangular section c will constitute approximately one entire half of the pocket, while the other two sections b and d together constitute the other half of the pocket. The manner of forming such article will now be described.

The knitted blank is preferably made on a circular latch needle machine of the type usinga single set of needles and sinkers. The machine will be lled with the number of needles necessary to give the desired width of fabric and will be operated with a reciprocal movement-so as to knit a course during movement in each direction. Suitable cams will beprovided toi gradually re` move needles from operation for narrowing the fabric, to simultaneously restore to operation needles removed for completing certain fashioning operations, and to gradually restore to operation needles removed for widening the fabric.

A straight short section of loopers waste a is first formed by knitting a number of courses. The last course I of section a will preferably be a loose course. The triangular section b is next formed by knitting a plurality of courses until the desired length has been attained. A small fashioning is made in the apex area of section a by gradually removing needles at the left edge of the section as progressive courses are knit. Thus, one needle may be removed every time the machine moves in one direction following the knitting of course I until, say, three needles have been removed from operation. The length of the courses is thus gradually reduced. When the desired number of needles have been withdrawn they are then all simultaneously returned to operation, still retaining the end loops of the various preliminary courses. The knitting then proceeds, and the result of this fashioning is designated by the fashioning line 2.

Immediately after the completion of the fashioning in the apex area, a further fashioning is commenced which continues throughout the knitting of the entire length of section b, resulting in the sloping edge as defined by fashionin'gv line` 3 which-forms the border between section b and section c, and giving section b its triangular form. .This main fashioning is carried out in the same manner'as the preliminary narrowing by gradually removing needles one at a time at the left edge of the section during movement of the machine in one direction. All of the knitted loops at the ends of the different courses are retained on the needles when they are removed preparatory to the knitting of the subsequent section c, which is to be formed integrally with section b. As will be noted from Fig. 1 the narrowing Vof section b, as dened by line 3, need not be carried across the entire Width of the section, although to avoid undue distortion of the fabric in the completed breast pocket it is preferred to leaveonly a relatively small number of knitted wales along the right margin of section b.

When section b has been completed by removing the last needle and knitting the last narrow course thereof, the knitting of the next section c is commenced. Such section is started with a narrow course, and as progressive courses are knit the needles previously removed during the formation of section b are gradually brought back into operation at the left side of section c so that the courses of section c become wider as knitting progresses. The needles are preferably returned two at a time. The removal of 'the needles during the knitting of section b takes vplace during movement of the machine in one direction and the return of the needles in the knitting of section c will occur during movement of the machine in the opposite direction.

When all of the needles havebeen returned the full width of section c will have been attained and the fashioning line 3 completed. A further short fashioning 4, similar to fashioning 2, may be introduced in the apex area of c byr gradually removing the needles one at a time as the knitting progresses, to a total, say, of three. When the last needle has been removed all those removed are then simultaneously brought back into operation. A small number of straight courses may then be knit to complete the apex area of c, and then an additional short fashioning designated by line 5 may be introduced by removing one needle at a time, say to a total of three, and then simultaneously reintroducing such needles and continuing the knitting. The last half of section c is narrowed as the knitting progresses by again gradually removing needles, one at a time, until the full length of section c has been attained. Fashioning line 6 and fashioning line 3 converge together, substantially to a point, and give section c the form of an equilateral triangle, of substantial length in a walewise direction at its base, which will cause the pocket to have an elongated shape.

After knitting of the last short course of section c, the knitting of section d is commenced and as progressive courses are knit the needles removed during the knitting of the last half of section c are gradually restored to operation, say two at a time, until the full width of section d has been attained. As soon as the last needle has been brought in at the left edge of section d a further short fashioning may be introduced in the apex area thereof by gradually removing the needles one at a time and then simultaneously bringing such needles back into operation. This results in the short fashioning line l. A loose course. 8 is knit, this being done preferably at the same time the needles removed in making the last shortening are vbrought back into operation. Thereafter a short section e of loopers waste is knit with a plurality of straight courses.

The breast pocket blank, as constituted of the successively knit triangular sections b, c and d, together with the loopers waste sections a and e at the opposite ends of the blank, is now comcut apart by severing through the loopers wasteV fabric which will be formed between section d of a preceding blank and section b of a following blank.

The breast pocket, as shown in Fig. 2, is formed from the blank of Fig. l by bringing together the ends of sections b and d and looping them together on a looping machine along the loose sources I and 8. The loopers waste sections a and e can be removed at the time of formation of the looping stitching l2.

As will be evident from a comparison of Figs. 1 and 2, the long isosceles triangular section c defines one entire half of the breast pocket, while the two smaller right angle triangular sections b and d together form the remainder half of the pocket. The knitted wales in each of the sections b, c and ai, as indicated by the lining of the. figures, run lengthwise of their respective marginal edges 3, I0 and II. The wales in sections b and d run perpendicular to their ends and form continuations of one another when the terminal courses I and 8 are joined together by the stitching I2. The wales of both adjoining sections b and c meet fashioning line 3 at an Aacute angle, and similarly the wales of both sections c and d meet fashioning line 6 at a corresponding angle. The fashioning lines 3 and 6y divide the pocket into upper and lower halves, the corresponding wales of which run generally horizontally and merge with each other at their ends along such lines.

The pocket will have the intended elongated generally oval cross-section by reason of the Wide angle formed at the apex between fashioning lines 3 and E, andthe lengthwalewise of `section c, and also because of the sharp angles.`

formed between the meeting ends of the wales of adjoining sections by reason of the combination of narrowing and widening operations at the fashioning lines.l

`Since the stretch of knitted fabric is in the direction of the `courses and crosswise of the wales, it will `be appreciated that as shown by the arrows in Fig. Z'the direction of stretch in the pocket in all of the various sections will be vertical in the middle area of the pocket and change only slightly in direction as the wales of the upper and lower sections come together gradually to meet along the fashioning lines 3 and 6.

Inasmuch as the lower half of the pocket is intended to lend support to the underpart of the breast, it `is found desirable to knit the same with a tighter stitch, using greater tension, than in the formation of the `upper half of the pocket. This practice will not change the direction of stretch but will cause the lower half to be firmer and have a less degree of stretch than the upper half. This feature of the invention is obtained by knitting sections b and d with a relatively tight stitch, and employing a looser stitch in the formation of section c, when the latter, as shown, constitutes the upper half of the pocket. Infthe event sections b and d are to constitute the upper half ofthe pocket and section c the lower half, section c will be knit with a tight stitch and the other sections with a looser stitch.

, Therblank for the pocket may be knit of any suitable kind of thread such as cotton, rayon or covered rubber yarn, and various stitch formations may be utilized in making the saine.

The short fashionings 1&5 and 'l are de sirable refinements of the invention adapted to give a nice curved effect and avoid buckling in the apex area of the pocket, but may be omitted. The invention is not to be construed as limited to the use in connection with the long section c of the particular sections b and d. The number and form of additional sections, and also the order in which the sections are knit, may be varied within the scope of the invention. However, the particular embodiment of the invention shown, comprising segments b, c and d, is very desirable since it can be made under a very simple knitting technique, and the shape of thek pocket is well suited to mold the breast and give the same a generally oval appearance. Y

inasmuch as the breast pocket is completely shaped by reason of the manner of knitting and fashioning the same, it will be evident from a consideration of Figs. 2, 3 and 4 that it is all ready to be set into a breast opening in a womans garment by merely stitching around its periphery as defined by the Wale-wise extending marginal edges 9, it and ii of the successive triangular sections.

In Figure 5 we have indicated breast pockets according to the invention set in a brassire. The pocket i3, corresponding to Fig. 2 and certain parts thereof being similarly identied, may be provided with an edging ifi, preferably elastic, extending around edge iii of the upper half of the pocket. A line of stitching i5 can be formed around the edges S and H of the sections constituting the lower half of the pocket to secure the same to the adjoining parts of the brassire. As will be noted from the drawing,

the pocket i3 may be tilted slightly so as to bring the lower edge 9 to a generally horizontal position and such edge may be relatively straight and parallel to the lower adjoining portion of the brassire. Adjacent the right end of the pocket I3 a small triangular section I6 of Swiss rib or other knitted fabric may be provided so that the upper elastic edging It may extend in a more or less straight line to join the lower portion of the brassire beyond the end of the marginal edge lil of the upper section of thebreast pocket. A large triangular Swiss rib or other knitted fabric section Il may be provided in the center of the brassire and secured to the marginal edge li of the lower left half of the breast pocket through the stitching l5. `An elastic securing band i8 will be provided at the lower extremity of the brassire to anchor the same to the body.

The left breast pocket i9 is similar to the pocket it and is secured in the brassire in a similar manner. Shoulder straps 2e will be anchored at the margins of the pockets i3 and I9 in their upper central areas.
