Title: Improvements in straight-bar knitting machines
IPC: D04B11/06
Filed: 1936-11-12
Abstract: 484,998. Knitting. BLACKBURN & SONS, Ltd., G., START, H. W., and START, E. Nov. 12, 1936, No. 30880. [Class 74 (ii)] Relates to improvements in fashioning on machines of the Cotton type whereby four sets of narrowing points E ... H for each division of work can be controlled from one narrowing screw M. In forming, e.g. stocking toes, it is usual for each set of points to transfer a number of loops and to narrow by depositing two loops on one of the corresponding needles. This requires that the inner groups of points F, H should sometimes be closed up to tho groups E, G and at other times stand one needlespace away. By a lever K<3> pivoted to a slide K fixed to the screw nut N, a tappet B<2> on a bracket B<3> attached to a bar B carrying the points H can be moved one needle-space to the left, thus separating the groups H and G. When the nut N is subsequently moved two needle-spaces to the left, a tappet K<1> on the slide K moves the bar B a further needle space to the left, and another tappet K<2> moves a bar D, carrying the points G, the full two needlespaces to the left, thus closing up the points G, H again. The points E and F are operated similarly by another lever pivoted to a slide fixed to the other screw nut. These levers carry rollers such as K<4> and are engaged by a rocking bar P and depressed by a spring P<2>. The displacement of the bars A, B is limited by the contact of stops such as B<4>, with the tappets K<1>. The bar P is carried by arms P<1>, on a shaft Q, which is geared to another shaft to which an arm is fixed. When the bar P is to be raised, this arm is caught and pulled down by a hook operated by the cam shaft. The tappets K<2> can be put out of action when the outer groups of points E, G are not required, e.g. for leg fashioning.
