KNITTED SHEATH OR CORSET AND PROCESS FOR THE MANUFACTURE OF THE SAME Filed Sept. 11. 1957 Patented Sept. 19, 1939 KNITTED SHEATH R CORSETAND PROC- ESS FOR THE MANUFACTURE OF THE SAME Edmond Boudios, Paris, France, assignor to Etablissements Aube, France Boudios, Romilly-sur- Seine,

Application September 11,1937, SerialNo. 163,487 I In France July 1, 1937 8 Claims. (Cl. 66-176) In the sheaths, corsets and other knitted goods of known manufacture, the threads, whether elastic or not, which are usedas woof threads in the meshes, assume a practically horizontal posi' tion when the said articles are worn.

The present invention has for its object a sheath or corset in which the woof threads form, at the front of the article, V-shaped parts whose points are downwardly directed and whose top parts are located on the lateral sides of the said article. Such a sheath or corset is adapted to raise the abdominal organs.

. The invention has further for its object a proc-" ess of manufacture of a sheath or corset of the aforesaid type, in which said article made of two pieces which are longitudinally assembled according to the middle vertical lines of the back L and front; each of the said pieces is obtained by the combination, on the one hand, of transfers, made in the same direction, of the meshe's of the .two parts of said piece which are situated on either side of a vertical line which is axial or practically axial, and on the other hand, of widenings or. narrowings according to the direction of the work upon one of the edges of the piece.

In the accompanying drawing, which is given solely by way of example:

Fig. 1 is a front view of a sheath, according to the invention.

Figs. 2 and 3 areltwo corresponding diagrams,

in elevational and plan views;

Fig. 4 is a diagram showing by way of example, in one of the two pieces forming the knitted sheath, a transfer of meshes to the left, in the two portions of this piece which are located on either side of the vertical axis of the work.

Fig; 5 is a diagram'of the same piece, supposed to be flat and seen on the wrong side, which is obtained by this simple transfer of meshes. 6 shows, in the flat position, and seen on the right side, one of the two halves of the sheath represented in Fig. 1, obtained by the combination of transfers of. meshes, of widenings on one edge, and of fashioning loops. In the embodiment shown in Fig.1, the sheat according to the invention consists of two pieces, P and Q, which are symmetrical with reference to the vertical longitudinal plane whose direction is from front to rear. The .two pieces P, and Q are assembled in the said plane, at the middle of the back, on the line- AB, and at the middle of the front, on the line CD. Each ofthe pieces is en-, tire, between these two lines, i. a, between the corresponding edges ab and 0d. The assembling at AB and CD can be effected by any suitable means, for instance by sewing, by attaching by the use of clasps, hooks, busks, lacing, etc. The two pieces P and Q, which are symmetrical with reference to the plane XX, each comprise an up- 5 are made.

per ribbed edge I, then a part! inwhich the rows .of meshes and the woof threads are horizontal 'clear to the bottom, the rows of meshes and the woof threads remain horizontal in the back part (see gh, Fig. 2) but are placed obliquely in the front part hi, the points i being fairly lower than the rear parts gh, in order to form, withthe corresponding threads of the other piece, a series of V-shaped parts whose points i are downwardly directed and situated on the front middle line of connection CD.

. The triangular space betweenthe first upper thread h i having its front part oblique, and the lastthread h? having its front part horizontal, is filled up by fashioning loops i.

' In like manner, atthe lower part, a fashioned portion 5 .fills the space between the last lower thread having its front part oblique and the lower horizontal front edge 6 of the sheath.

When the sheath is in place upon the body, it becomes enlarged, and increases from the section S to the section S (Fig. 3). It will be at once observed that a tension T on a woof thread (Fig. 2) has a horizontal component. H producing a centripefal tightening action U (Fig. 3) and a vertical component V (Fig. 2) which produces the desired raising action.

The manufacture of the sheath is effected in the following manner, supposing the knitting begins at the bottom.

The pieces 'P and Q are knitted separately.

- For each piece the ribbed edge 6 is knitted in the known manner. Then the fashioned portions the part corresponding to the woof threads which extend from one edge ab of the piece to the other cd and whose portions such as ht, which are After these latter, there is knitted adapted to form one of the two halves of the front part of the sheath, are disposed obliquely and are directed downward from the rear to the front.

This part of each-of the pieces P-Q, which forms the essential feature of the invention, is

obtained in the manner shown diagrammatically in Fig. 4,which relates to the piece P seen at the back part, and on which the points represent the in front, i. e., to the line of folding of the piece,

if it is supposed that the front part of the sheath is folded upon the rear part.

Let us consider the first two rows of meshes, E and F represented by points as already mentioned. In the next row G, it is supposed that a transfer of meshes has been made to the left, in each of the two halves of the piece, situated on either side of the axis ef, with the exception of a few meshes at .the middle. The left-hand meshes form an empty space in which are formed two other meshes 1, and the edge becomes inclined at c'd' with reference -to the axis e). The right-hand meshes have their number reduced by two, and the edge becomes inclined at ab in the same direction as the edge c'd'. The next row H has no transfer of meshes. The work continues in this manner; The transfers of one or more pairs of divisions -take place every nth row, and n may be variable and may depend upon the form to be given to the piece. Obviously, inextensible or elastic weft threads may be inserted in part or whole of the rows of meshes in known manner as disclosed in the above mentioned U. S. Patent 1,675,691.

If such an operation, performed as above indicated, were pursued as far as the upper thread i h a (Fig. the result will be the piece P which is shown diagrammatically in Fig. 5. This piece would have the outline a b c d (not considupon the rear portion a e f b about the line ef, the

line h i will be inclined downwardly with relation to the line ea, and the front edge cd will assume an oblique position with relationto the'edge ab which is substantially vertical when the sheath is applied on the body. It is thus necessary to remove from the piece the triangle i dc' in order that the front edge shall be vertical when the front portion is folded upon the rear portion and shall have a position 011' which is practically symmetrical with the edge ab with reference to the axis ef. This triangle is removed during the knitting operation by making the usual narrowings in the edge of the piece during the progress or the knitting of this part.

However, the simple combination of general transfers to the left and of narrowings of the left-hand edge, would produce a piece in which the ripper point of the front edge would be lower than the upper point of the rear edge.

In order to bring these two points to the same level, the fashioning loops 4 will be next produced. Then the part 2 is formed, by making (in known manner) symmetrical transfers of meshes on both halves of the piece which are situated on either side of the axis eflthese transfers being made'as widenings. The work is finished by the ribbed edge I, in the known manner.

For the piece Q, the operation is performed in an analogous manner the general transfers being made to the right, while the narrowings of .the

edge are made onthe right.

carried out entirely by hand or by mechanical devices.

Obviously, the invention is not limited to the embodiments herein described and represented, which are given solely by way of example. fashioned portions 4 and 5 of the present example might be eliminated, if necessary.
