Y., assignor to Sam Feinstein, Rebecca Feinstein, and Louis Feinstein, doing business as Feinstein Knitting Mills, Inc., New York, N. Y. Application February 3, 1945, Serial No. 575,954 3 Claims. 1 This invention relates to a method of manu facturing a knitted fabric, Particularly, it is an object of my invention to arrange the links of a pattern chain in such a manner so that the machine will automatically knit a diamond-shaped pattern. More particularly, I have provided an arrange (01. 6.6-—86) 2 such a position that the needles 58 in the bank slide up and down, but leave sufficient space to permit the fabric to cast oil. The needle bar 5| is raised and lowered in the usual manner by the needle cams 54-—54 which may either be single or double action cams. Cam-s 54 act through cam arms 55 which are pivoted at 55 and restricted lifter rods 5'! on which the needle bar 5| is mounted, the needle cams '54 are on the main ment of links for the pattern chain which oper ates the guide bar to cause the guide bar to make ' ' two separate stitches on the ?rst working needle 10 shaft 58. I have illustrated a machine showing two guide and alternatively on the adjacent working needle bars, one guide bar ‘being numbered 59, and the and then repeat the operation on the ?rst and adjacent working needles continually and auto matically, then causing another guide bar to make one stitch on the ?rst working needle and lying in on the second stitch oi the ?rst working needle then producing one stitch on the adjacent opposed guide bar being numbered Bil, however, I do not desire to con?ne myself to the use of only two guide bars, since the machine can read ily be adapted to use any number of guide bars. The guide bars control the yarn for knitting the fabric. The pattern chains illustrated in Figs. working needle and lying in the yarn on the sec 3 and 4 control the movements of guide bars 59 ond stitch of the second Working needle, the chain and 60. Guide bar 59 is controlled by a pattern then causing the operation to be repeated on the chain illustrated in Fig. 3, while guide bar 86 is ?rst and second working needles continually and controlled by the pattern chain illustrated in automatically, the guide bars being caused to Fig, 1i. The yarns 5| are fed to the needles operate simultaneously, interlocking the yarns in through the guides 62 of the guide bar 59, while order to form a diamond pattern knitted fabric. For a fuller understanding of the nature and 25 the yarns 5i to 65 are fed tov the needles through the guides $2 and 53 respectively of the guide bars objects of my invention, reference is had to the 59 and 50 respectively; the yarns GI and 64 of} following detailed description in connection with which pass between the needles as the guide bars the accompanying drawings, in which: are rocked back and forth. While the guides 62 Fig, 1 is an end elevation of a single needle and 63 are operated independently, guides 62 and barred knitting machine. ‘ 63 are hung on a cradle 54 and passed back and Fig. 2 is a side elevation of the greatest part forth between the needles in parallel relation of the aforesaid knitting machine in connection ship as a single unit. The guide bars 59 and B0 with a schematic diagram of the guide bar oper are suspended by two or more hangers 65 through ating mechanism. whose lower end a horizontal pin 65, located at Fig. 3 is an elevation of a group of links of a the top of the guide bar, slides freely, thus en pattern chain which controls one bar of the mechanism, the said chain being enlarged in pro portion to the diagram of the machine, however, abling the guide bar to slide longitudinally through the cradle. The suspension is made firm by the brackets Bl which are fastened on the ends the links are pictured smaller than the links of 40 of the guide bar and are slideably suspended on the actual chain; the cradle by the rods 68. The cradle 64 is locked Fig. 4 is an elevation of another group of links by a slotted arm 69 on one end of the cradle and in a pattern chain which work in connection with a vertical connection rod is which is adiusta'bly the pattern chain shown in Fig. 3, to produce the fastened to the outer end of the slotted arm. The pattern of a knitted fabric. lower end of connecting rod 10 is forked and ‘ Fig. 5 is a diagrammatic view illustrating the straddles the main shaft 58. Mounted on the relative position of the threads with relation to connecting rod ‘iii is a roller ‘H lying in a grooved the needles of the knitting machine. cam 12 on the main shaft 58. As the cam 12 re The main portions of the knitting machine volves, the connecting rod 10 is raised and low used for the purposes of illustrating my inven 50 ered and the cradle 64 is rocked back and forth, tion are shown in Figs. 1 and 2. There is one the movement being so timed with relation to straight bank latch, needles 5!) which are mount the needle bar '5! descends just after the indi ed on a needle bar 5| in a manner Well-known in vidual thread guides pass between the needles to the art. The needle bar is adapted to slide up the same side of the machine as the needle bar and down in a needle bed 52 which is rigidly fastened to the main frame '53 of the machine in 55 5|. The yarns 6| are fed to guide bar 59 from 2,409,026 4 warped beam 13 which is mounted on a frame 14. Yarns 64 are fed to guide bar 60 from warped beam 15 which is mounted on the frame 14. on needle one and while thread 80 makes stitch 2 on needle one, thread 8| lays in through the stitch made on needle one by thread 80, (the stitch on needle one is controlled by the ?rst two links 0, 2 of Fig. 4, while the lay in stitch is con trolled by the third and fourth links (I), 0 of the In the method of knitting my fabrics, the loops are formed by the guide bars which lap the yarns around the needles, such lapping being done by combinations of. the rocking movement herein Fig. 4), and then thread 8| passes to needle two before described, and the traverse movement con making'a stitch on needle two, and while thread trolled by the pattern chains illustrated in Figs 3 80 makes the second stitch on needle two; thread and 4. In place of the pattern chains illustrated 10 8| lays in through the stitch made on needle two in Figs. 3 and 4, it should be understood that the same movements which are created by the pat tern chains shown in Figs. 3 and 4 can be dupli cated by the use of cut wheels, the edges of which are cut at varying distances from the center to create the different heights. This is an equiv is alent for the links of the chains illustrated in Figs. 3 and 4 which are also of varying height. In Figs. 3 and 4, I have illustrated the two pat tern chains consisting of links of different height 20 to control the pattern in my method of knitting diamond-shaped knitted fabric. The links of the by thread 80, (the second stitch being controlled by the ?fth and sixth links-4, 2 of Fig. 4, and the lay in stitch being controlled by the seventh and eighth links 4, 4 of Fig. 4). The fabric heretofore described and the rela tive heights of the links to create this fabric can be made by reversing the direction of the threads, that is, threads that loop around the needles from right to left can be looped around the needles from left to right so that in the ?nal appearance and end result the knitted fabric made by this method will look exactly the same. chains are designated by numbers which appear It should be distinctly understood that one in the center of the links and designate the rel skilled in the art can readily rearrange the links ative height of the links. To form the knitted 25 of the chains shown in Figs. 3 and 4 in order to fabric, it is necessary to set up the chains with create the same type of diamond-shaped knitted such links also known as pattern wheels accord fabric, however, that does not depart from the ing to certain formulas. One formula for the general spirit of the invention since the heights production of my knitted fabric is represented in of the links control the direction of the turn Figs. 3 and 4 as follows: (Fig. 3) chain |_0, 2, 0, 30 around the needle, that is, whether or not the 2, 4, 2, 4, 2; (Fig. 4) chain 2—0, 2, 0, 0, 4, 2, 4, 4. turn is made from right to left or left to right The chains illustrated in Figs. 3 and 4 are placed does not change the character of the fabric. around drum ‘"5, and these chains automatically It is therefore understood that various changes create the knitted fabric of the diamond shaped and modi?cations may be made without depart pattern of my creation.
