A patterning assembly 161, Figs. 3, 5, 6 and 7 is mounted in a circular machine so as to be readily removable to enable adjustments to be made to it and to facilitate access to the needle cylinder the construction being such that the subsequent remounting does not require retiming of the mechanism with the cylinder. Two assemblies are provided in the machine and each comprises a pattern drum 61 mounted between top and bottom bed plates 162, 163 on a shaft 165. The drum is provided with jacks 100 which engage levers 101 controlling a bank of slides 51 which are normally resiliently urged upwardly to engage needle jacks to effect selection of the needles. The levers 101 are pivoted at 102 so that the jacks 100 in the drum cause the levers to withdraw their corresponding slides. The slides are also controlled in groups by stops 111 on sliding bar 112 which each engage the tail ends 105 of a group of slides when projected to pivot the levers 101 and cause the corresponding slides 51 to be withdrawn from action. The stops 111 are controlled by the bars 112 having projections 117 which are engageable by levers 116 controlled by push rods 115 from a lower pattern drum. The bars 112 are mounted on a support 113 also carrying the levers 116 and which support is mounted between the bed plates 162, 163.

Abstract: 985, 704. Shuttleless looms. SOC. ALSACIENNE DE CONSTRUCTION MECANIQUES. May 15, 1961 [Feb. 14,1961], No. 17531/61. Heading D1E. In a loom having two weft inserting needles meeting at the middle of the shed to transfer weft from one to the other, the needles align themselves under forces produced by gravity and the acceleration of the slay as it moves forward from rear dead centre; the heads of the needles are thereby urged down on to the slay beam and back against the reed. Weft inserters, Fig. 14. The cut end of the weft 302 lies vertically across the forked head of a needle 214, being located by a notch 319 and gripped by a rigid jaw 311 and a spring jaw 312. When the needles meet, the weft snaps into a hook 324 on the needle 215 and is gripped between the hook and a jaw 321; as the needles separate, the cut end is pulled out of the needle 214. Operating weft inserters, Fig. 1. Each needle is operated by a link 214, to which is is coupled by a ball-type joint which leaves the needles free to align themselves as described above; stops 308, 309 keep the needles on the slay beam during the rearward acceleration of the slay. The needles can be readily disconnected from the links 214 and removed from the loom to enable weaving faults to be corrected. Each link 214 is operated by a lever 278 actuated by a bellcrank 285; the pivot at the bottom of the lever 278 is vertically slidable in a guide 283, thereby producing straight-line movement of the link 214. The bell cranks at both ends of the loom are oscillated by connecting rods 291 and levers 293 on a torsion shaft 294 oscillated by cams 297, 302 on the crank shaft 208. To prevent blacklash, the follower 296 contacts the cam 297 at the rear of the crank shaft, while the follower at the other end of the loom contacts the cam 302 forward of the crank shaft, the two followers being pressed against the cams by the torsional stress in the shaft 294. Specification 985,703 is referred to.
