Abstract

466,043. Knitting-machines. BOOTON, Ltd., W. E., and BOOTON, W. E. Nov. 23, 1935, No. 32513. [Class 74 (ii)] Selecting mechanism comprises a number of resilient elements movable to and fro in a tricked bed, means for so moving said elements, means for selecting certain of said elements, and means for springing selected elements, or permitting selected elements to spring, into or out of the range of said moving means. As shown in Fig. 1, resilient U-shaped elements 10 are slidably mounted in deepened tricks of a needle cylinder, one limb of each element being operatively connected to an instrument 12, which may be a plating instrument of the type described in Specifications 406,657 and 430,498, and the other provided with a butt 14 that can be moved out of the path of a cam 20 by inward movement of a depresser bit 15. Each bit 15 is held against outward and vertical movement by a split ring 19 and is provided with frangible butts 16 for actuation by pattern means comprising a pegged drum and a battery of plungers 27, e.g. of the type described in Specification 435,122. In order to permit of a wide selection, two jack-raising cams 20a, 20b may be provided and the jacks and bits 10 divided into two groups 15A, 15B that can be actuated by a master plunger 27A or 27B to move the associated jacks clear of one of the cams 20a, 20b, the selection at the other cam being effected by plungers 27a, 27b. The pattern drum 24, Fig. 4, may be racked one or two teeth at a time according to the spacing of studs 29 which co-operate with a finger 33 and limit the stroke of the clawker 25. The motion of the drum can be interrupted by a bluff 36 pivotally mounted in one of a circular series of holes 34 and adapted to be moved to operative position by the action of a control member on the end 39 of a pivoted catch 37.
