Definitions

  • the present invention relates to nonraveling hosiery and the manufacture thereof, and it is moreespecially applicable to articles made on a flat frame and more especially on a Cotton frame.
  • the knitted fabric according to the present invention is free from the first mentioned drawback in that it has a smooth appearance while keeping a satisfactory elasticity.
  • the manufacture of the knitted fabric requires but an easy modification of the frame.
  • the latter may be completed on the one hand by an auxiliary presser member, disposed parallelly to the usual pressure member, which is kept without any modification in its form or its operation, on the other hand by a series of small blades or swinging parts disposed opposite each needle, between the latter and the usual presser member, said swinging parts being carried by the frame of the knocking over bits.
  • the knocking over bits are subjected to a slight modification in order to create behind the existing throat a notch or second throat.
  • the short yarn is sunk and shaped in such manner as to constitute alternately, from one wale of loops to the other (the word wale designating the vertical lines of loops) a long loop extending over two successive courses of loops and a short loop 5 formed on the first of the two above mentioned courses of loops.
  • the short yarn is sunk in such manner as to constitute on the other hand a retaining loop for the long loop above mentioned and on the other hand in the next course a loop 10 which is superposed to the short loop constituted by the long yarn.
  • the long yarn forms in each course, alternately, a long loop and a short loop
  • the short yarn forms, alternately, a loop 15 which is juxtaposed to the short loop constituted.
  • the knitted fabric made according to this method has a connection not only in the 0 horizontal and. vertical directions but also diagonally, which has for its effect to eliminate the injurious action of a longitudinal pull exerted parallelly to the wales of loops, whereas the action of a transverse pull, that is to say along a 5 course of loops is remedied by the double length of the long loops extending over two courses of loops, It is therefore clear that the article knitted according to this process cannot ravel at all, 3 an advantage which is particularly advantageous in the case of stockings or similar articles.
  • the long loop formed by the long yarn can extend over-any number of courses of loops, for instance three successive courses. Furthermore, it is possible to insert between the alternate courses of long and short loops (the long loops extending over two successive courses), a course of smooth 40 short loops ln which all the needles form short loops with a short yam. In such an arrangement, I obtain a pattern similar tothat of the Jacquard, the double loops (two juxtaposed loops) ,which project with respect to the simple smooth loops, forming patterns. Of course, stead of a single course of smooth loops, I may interpose a great number-of courses of said loops, in such manner'that'other patterns appear on the right side of the knitted fabric.

  • Fig. 2 shows the back side of a knitted fabric manufactured according to the present invention
  • Figs. 3 and 4 show, on the back side, modifications of knitted fabrics made according to the present invention
  • Fig. 5 is a transverse section, on an enlarged scale, opposite a needle, showing the arrangement of the diiferent members necessary for carrying out the present invention
  • Figs. 6 and '7 are views, analogous to Fig; 5, some parts being in a different position;
  • Fig. 8 is a plan view of the auxiliary presser member
  • Fig. 9 is a detail view of a knocking over bit modified according to the invention.
  • Fig. 10 is a perspective diagrammatical view showing how the elements shown by Fig. 5 are controlled;
  • Figs. 11 to 24 are diagrammatical views illustrating the difierent steps of the manufacture of the knitted fabric according to the present inan ordinary yention.
  • the frame is completed by a second presser member, or auxiliary presser 5, and by a series of small blades or swinging parts 6.
  • a second presser member or auxiliary presser 5
  • a series of small blades or swinging parts 6 Each of these blades is located opposite a needle and can pivot about axis 1 in the direction of arrow F under the action of the presser member 5 and against the action of spring 8.
  • the axis I is carried by the frame 1a of the knocking over bits.
  • the drive of the presser member 5 is obtained in the following manner:
  • Arms 9 (Figs. 5 and 10) connectpresser member 5 to levers I0 keyed on a shaft II.
  • This shaft II is subjected to the action of a cam I2 throughthe .medium of the lever I3, pivoted at I4.
  • This lever I3 is articulated'at I5 to a. link I5 which is pivotally connected at I8 to a lever I1 keyed on shaft II, so that said shaft II is given a reciprocating oscillatory motion which produces the forward and rearward movement of the presser member 5, which thus acts on blades 6 for tipping them in the direction of arrow F.
  • Shaft I is further subjected to a translatory movement in the direction of its axis, said movement being produced by the action of a wedge am l9 acting upon roller 20.
  • This cam I9 is displaced vertically by the action of the cam 2
  • the movement is transmitted through arm 23, pivoted at 24, connected through its end a 25 with the link and lever structure 26-21,
  • lever 21 being keyed on shaft '29 and driving cam 30 in connection with roller.3
  • a spring 35 ensures the return of shaft II and keeps roller 20 in contact with cam I9.
  • connection between shaft I I and lever I1 is such as to permit the free sliding in the longitudinal direction 'of said shaft
  • a disc 36, on which roller 31 runs normally, is juxtaposed to cam 2
  • roller 31 The control of roller 31 can be carried out as follows:
  • a lever 38 is pivoted at 39 and is connected to a shaft 40 at one of the ends of which there is pivotally mounted a bell crank lever 4
  • the arm 43 of this lever can be lifted by a boss 44 carried by an endless chain 45 which is given a suitable translatory movement.
  • boss 45 when meeting arm 43, causes lever 38 to pivot against the action of return spring 46, in such manner that roller 31 is brought into coaction with cam 2
  • the auxiliary presser member 5 (Fig. 10) has its front edge (on the side carrying swinging members 6) provided with teeth as it is visible on the plan view of Fig. 8.
  • the pitch of these teeth is such that opposite the respective swinging members 6, there .is alternately a tooth 48 and a hollow 49.
  • Swinging members 6 each terminated, as shown by Fig. 5, by a nose 50 arranged opposite the usual presser member 4. It is through these noses 50 that the needles are pressed, that is to say that the ends of their beards are driven into their eyes.
  • the knocking over bits 3 are of particular shape in that they are completed by a throat 5
  • this yarn is shaped in such manner as to constitute at h a small loop, in the next wale a long loop 2' and again a small loop h and so on, that is to say alternately a small and .a long loop.
  • yarn'g is shaped in such manner as to constitute a long loop 2' in line with the small loop 71. and-a small loop h in line with the long loop 2'.
  • the small loops h or II. are formed by two yarns, to wit yarn g or g and the yarn m or 112.
  • Fig. 2 also shows that, despite the arrangement of yarns m and g, of different lengths,
  • Diagrams 11 to 24 illustrate how the above knitted fabric described with reference to Fig. 2, can be produced on the Cotton frame.
  • Figs. 11 and-l8 show the needle I of wale p and the needle Ia of wale q, supplied with the yarn m which has just been distributed and has been shaped by sinkers 2.
  • the needles fitted with the yarn m thus move downas shown by Figs. 12 and 19.
  • FIG. 5 shows the elements of the frame whenneedle I is pressed by the'action of the auxiliary presser member 5.
  • This yarn g is distributed of a length greater than the length of yarn m precedingly distributed.
  • Figs. 14 and 21 show the yarn g caught respectively by needles I and la after said yarn has been sunk by sinkers 2. It will be noted (Fig. 21) that yarn m at the place of needle la. is carried by the nib 53 of the bit 3, whereas the sinker loop of the needle loop 1' is engaged in the usual throat 52.
  • Fig. 4 relates to another embodiment of nonraveling knitted fabric in which there is interposed between the long loop z' and the double short loop h (Fig. 2) a smooth course of simple loops.
  • This knitted fabric is obtained in the following manner: After having made loop 71. on the needle'l of walep, I distribute a short yarn r form patterns.
