mesne assignments, to Standard Hosiery Mills, Burlington, N. C., a corporation of North Carolina Application January 23, 1950, Serial No. 139,996
33 Claims. (Cl. 66-50) fabrics by introducing yarns of two or more different colors at points immediately adjacent each other to the needle circle and whereby these yarns may be introduced to the needles in such a manner as to be knitted on some of the needles simultaneously while being knitted on other of the needles independently, according to a desired pattern.
This invention is a continuation in part of my copending application, Serial No. 80,273, filed March 8, 1949, and entitled Apparatus for Knitting Float Patterns, now Patent No. 2,516,697 of July 25, 1950.
Theprimary object of this invention is to provide improvements in a knitting machine of a type having a needle cylinder in the periphery of which vertically movable pattern jacks are mounted and each of the pattern jacks having coinciding needle jacks and latch needles associated therewith, the pattern jacks being controlled by the usual pattern means such as the trick wheel,
These improvements are also employed in conjunction with an auxiliary yarn feed station disposed in advance of a main yarn feed station adjacent the needle circle and include means for selectively positioning the needles at four different elevations at the auxiliary yarn feed station, namely, a lower elevation, first and second intermediate elevations, and a higher elevation and providing other means for either lowering or elevating the needles to a lower or an upper elevation, after moving past the auxiliary yarn feed station and upon passing the main yarn feed station, so as to selectively take the yarn from the auxiliary yarn feed station as well as to selectively take the yarn from the main yarn feed station while, at other times, movingother of the needles to such an elevation as to cause the needles to pass above the stitch cams retaining the previous loops thereon. This makes possible, in one instance, the taking of the yarn from the first yarn feed station but not taking the yarn from the second yarn feed station and thus knitting the yarn from only the first yarn feed station, which is the hereinbefore described auxiliary yarn feed station. This also makes possible in a second instance, the taking of the yarn from both of the yarn feed stations and knitting both of the yarns simultaneously and, in a third instance, this makes possible the taking of the yarn from only the second or main yarn feed station thus resulting in only the yarn from the main yarn feed station being knitted into the fabric.
It is another object of this invention to provide a fabric structure wherein two or more different colors of yarn may be knitted in the forming of patterns of a type wherein the suture formed by the juncture of two colors of yarn extends at an angle relative to the plane of the wales and the courses being knitted and wherein, for example, a first needle will take both colors of yarn, knitting the two colors simultaneously while another 2,726,525, Patented Dec. 13, 1955 needle disposed on each side of the first needle may fail to take the yarn according to a desired pattern for a predetermined number of courses, the yarns being floated between the first needle and the needles disposed adjacent remote sides of the needle disposed to each side of the first needle. The needle disposed each side of the first needle remains inactive, during the knitting of several courses, merely retaining the loops and all additional yarn thereon.
It is still another object of this invention to provide pattern controlled means for varying the number of steps the trick wheel or selector drum moves to complete a revolution and to vary the time at which a step in movement is imparted to the trick wheel relative to a predetermined point on the periphery of the needle cylinder, upon rotation thereof, so as to insure that a proper pat: terning may be transmitted from the selector drum to those pattern jacks whose butts which are responsive to the patterning on the trick wheel and normally disposed in the vertical plane of the needle cylinder at which the usual step in rotation is transmitted to the selector drum, may be positioned to one side of this point when these particular butts are to be acted upon through the conventional selector fingers associated with the selector drum. 1
Some of the objects of the invention having been stated, other objects will appear as the description proceeds, when taken in connection with the accompanying drawings in which- Figure 1 is a front elevation of a portion of a Scott and Williams circular knitting machine and wherein many of the parts are shown schematically and showing parts of the present invention applied thereto;
