PatentedJune 17,193!) UNITED STATES PAUL OI CHEH NITZ, GERMANY ENDLESS PATTERN BAND FOB TEXTILE MACHINERY Application fled mm 1:, 1m, Scrial'No. 225,950, and in Germany June 18, 1927.
My invention relates to textile machinery and more especially to patterning mechanism adapted for use more especially in connection with circular knitting machines. It"
has particular reference to an endless pattern band which is arranged'in a new and advantageous manner, which enables long endless bands to be accommodated in the machine and to be supported therein in a more efficient mannerthan was hitherto possible.
An embodiment of the invention is illustrated, by way of example, in the accompanying drawing, in which i Fig. 1 shows the pattern band in'a perspective view. v
Fig. 2 shows the s rocket wheel with the pattern band and with a portion of the knitting machine viewed from the side, the machine being shown in section; 30 Fig. 3 is a top plan view of the parts shown in Fig; 2, partly in section.
That portion 2 of the endless pattern band 1 which is inoperative for the time being, is wound into a flat spiral like a clockspring, which is held on all sides between rollers 3. The operative portion of the pattern-band starts from the inner side of the spiral; passing around a drum or wheel 4 and then over a sprocket wheel 5 to return to-the spiral from the outer side. At a suitable point such as a; the band acts by means of slots 6 or other perforations provided therein upon the heels of the needles or jacks of the knitting-machine, but it may also be substituted 'in other machines for the jar.- quard apparatus. A spur-wheel 7 serves to rotate the sprocket wheel 5 the teeth 8 of which convey the pattern-band 1 by .engaging in holes 9 near the upper edge of band order to prevent those portions of the band, which are not perforated, from being deformed in contact with the heels of the jacks, the sprocket wheel has projecting ribs 10 formed onits rim between radial indentations, the solid portions 12 of the pattern hand between these slots being supported by these ribs. The indentations 15 are spaced in accordance with the spacin of the .wbund into a flat spiral, the operative poisolid portions 12 of the pattern band these solid portions cannot bend under the ressure exerted upon them by the heels 0 the jacks.- The heels 13 of these jacks which remain at rest are, therefore, properly pushed back, the heels of the other jacks pass.- ing freely through the slots 6 in the pattern band 1.
I wish it to be understood that I do not desire to be limited to the exact details of to construction shown and described for obvious modifications will occur to a person skilled in the art.
I claim 1. A knitting machine oomprisinga needle bed arranged to describe a circle, an endless apertured pattern band, means for supporting the operative portion of said band, means for transporting said band to operative pattern selecting position, the inoperative portion of said band being wound into a flat spiral, the operative'portion extending from the inner and outer part ofthe spiral as a continuous band around said trans orting means and to pattern selecting position and means for driving said transporting means in synchronism with said needle bed to transport said pattern band from said spiral to the operative position of pattern selection and back toinoperative position in the spiral. I I
2. A knitting machine comprismg a needle bed arranged to describe a circle, an endlessapertured pattern band, means for supporting the operative portion of said 5 band, asprocket wheel for transporting said band to operative pattern selectingposition, the inoperative portion of said band being tion extending from the inner and outer 9 part of the spiral as a continuous band around said transporting wheel and to pattern selecting position and means for drivingsaid transporting wheel in synchronism with said :needle bed to transport said pattern band from said spiral to the operative position of pattern selection and back to inoperativeposition inthe spiral, sald jacks 11. The ribs 10 thus supporting the sprocket wheel being formed on its circum- 10o :ference ivith; indentations re with the apertures of said band, r1 formed between adjoining indentations acting as suprts for the nonapertu 'ed portions of said d; n In testimony whereof I aflix 'n y signature.
