SB INTERNATIONAL EXHIBITION, 1876. work was produced, the needles were all re-transferred to the main cylinder. By changing the needles in this way, it was possible to knit a stocking with the rib-top and plain-leg, and, if desired, fancy ribbed stripes of various lengths and widths could be formed in the plain knitted ground. Patent No. 149,813. Gimson & Coltman Circular Ribbing-Machine, Leicester, England. This machine used a vertical and horizontal circular series of latched needles, and was for the production of heavy work, Cardigan jackets, etc. It employed twelve feeders for “ polka-stitch” rib, and half that number for plain “ one and one” rib-work. The vertical needles were reciprocated as usual, by cams, on a revolving cylinder. The circular needle-bed for the vertical needles was raised or lowered through the action of two rings provided with inclined faces. The cam-plates for operating the horizontal needles were also correspond ingly changed by similar inclined rings, these changes drawing the loops more or less, for loosely- or closely-knitted fabrics. To change from “ polka” to plain rib, the cam-plate for the hori zontal needles was shifted to the right by hand, until the feeder, which before acted only to feed the vertical or frame needles, was in position to feed both sets of needles, and then the threads which fed the horizontal or machine needles were broken off. To make this change from “polka” rib so as to properly finish a jacket, an annular plate or disk having inclined slots, in which rested pins which projected from the needle-actuating cams for the horizontal needles, was moved so as to draw the cams and horizontal needles back far enough to allow the bed for the horizontal needles to be moved sufficiently to shift the horizontal needles one needle to the right or left, and then the machine was again started to knit as usual, each loop thereby being thrown one loop or rib to the right or left, to cross the stitches and make an end finish. The distance that the horizontal needles were reciprocated beyond the edge of the carrying-bed or plate was regu lated by means of a studded ring provided with pins adapted to enter slots in projections attached to the cam-sections. For sleeve-work the number of needles in each ring was decreased, and only two feeders were used. This firm also exhibited a machine provided with two sets of needles, and adapted to knit “ rib-tops” with slack courses, and striped or not, as desired. The thread-carriers were thrown into and out of operation as desired, according to the indications of a pattern- surface. The machine produced excellent work. It was stated that it could produce forty dozen rib-tops of average length in a day of ten
