Abstract

422,801. Knitting. HOSIERY DEVELOPMENTS, Ltd., 30, Park Row, and MILLS, R. K., 3, Edwards Lane, Sherwood, both in Nottingham. Aug. 28, 1933, No. 23832. [Class 74 (ii)] Special seamless hose with patterned or ornamental stitch effects such as openwork clocks and/ or a fancy garter band of tuckwork and /or a picot edge is knitted in the locked-loop fabric described in Specification 329,098, [Class 74 (ii)], on a two-feeder circular machine. Heels and toes may be made of plain fabric. The number of needles over which the splicing yarn is laid may be progressively varied. The main yarn is locked or knitted at one feed and a much finer yarn is used at the other feed. After a needle has formed a stitch from the main yarn it is raised and lowered to clear the main yarn loop from the top latch and bring it below both latches. The locking yarn is then fed between the latches, the loops being measured on projected sinkers. Beneath each needle and in the same trick there is a jack 12 provided with a lowermost butt 19<a>, 19<b>. Each jack has also a long or a short butt 50 at one, at least, of seven upper levels. The jacks are acted on to select the needles by spring-urged cams 20, 21 controlled by a ring 14 in the vertical tricks of which aro placed bits 35, Fig. 12, with butts 35a on six or seven different levels. These act on nested levers 51, the upper ends of which engage projections such as 38 attached to the cams 20, 21 which are thus pulled out to miss the corresponding long butts on jacks 12. Tuckwork, picot edging and mock fashioning marks are produced by acting on the butts 19<a>, 19<b> with a radially movable clearing cam 18. During heel and toe work this cam is kept out of action by the main pattern drum, the widening picker being released by the same means. For producing openwork by float plating two yarns are fed at the main feed station at different heights or angles, and the needles are so divided by selection on the jacks that some take one yarn and others both. When formation of openwork is confined to two diametrically opposite groups of needles, the jacks of which are provided with specially short operating butts, clocks are formed. The bits in the trick ring 14 that are employed for clocking have butts 35<a> at seven different levels. As the ring 14 is stepped round, these butts act on the associated levers 51 and partially withdraw the cams 20, 21. During heel and toe work, or at other times when the formation of openwork is not required, the levers 51 are all held out of contact with the ring 14 by the main pattern drum. To permit the cams 20, 21, when completely withdrawn to be reintroduced, when desired, a group of jacks at each intermediate level is provided with extra long butts. To produce a fancy garter tuckwork band the clearing cam 18 is withdrawn and the needles, which would otherwise all tuck, are cleared selectively by the cams 20. To produce the garter band by float plating, the cam 18 is retained in operative position and the cams 20 are withdrawn selectively while needles not raised by cams 20 only take one yarn. Fig. 22 shows mechanism for controlling the splicing feeder 80. When the push rod 81 is lowered to bring the feeder into action a projection 82 is brought on to one end of a pivoted cross lever 83. Twice in each resolution of the main shaft 84 the opposite end of this lever is depressed by a lever 85, pivoted at 86 to a sliding rod 87, to render the feeder inoperative. A cam 88 rocks an arm 89 pivoted at 89<a> and have a projection 91 which comes under the end 92 of the lever 85 and rocks it. By longitudinally adjusting the lever 85, the time during which the projection 91 remains under the end 92 and hence the period for which the lever 85 is tilted and the feeder 80 raised can be varied. The lever 85 is adjusted by a cam 94 acting on the rod 87. The cam 94 is rocked by a wheel 97 driven by a hook plate 98 from the arm 89. The rocking movement is terminated by the arrival under the pawl 98 of a projection 100 and is recommenced by a pawl 101. A gusset toe may be knitted on about half the needles and a heel pouch on a smaller number. The heel may also be gussetted. Specifications 330,041, [Class 74 (ii)], 376,837, and 422,779 also are referred to.
