Abstract

164,391. Bell, F. J. T., Bell, H. C., and Twin Bobbin Sewing Machine Co., Ltd. Dec. 5, 1919. Sewing-machines; lock-stitching by hooks.-An oscillating lock stitch hook or other loop-taker is driven by flexible connections from a wheel which is oscillated by link-work. A hook 5 is mounted on an oblique pivot pin 4 and a wheel J is mounted on a similarly oblique spindle. Two lengths of chain M, N have their ends fixed to the wheel J and to the hook body; separate grooves being provided in the latter for the two chains. The ends of the chain carried by the wheel are secured in a screwed washer combination P which can be moved radially to adjust the tension of the chains. The wheel is oscillated by sliding connection of a pin K upon it with a link D and, since the wheel plane is not parallel with the plane in which the link moves, the pin is free to slide axially and laterally in a slot. The mechanism may be modified to impart a continuous rotation to the hook. It is shown applied to an oscillating hook which is described in Specification 164,390.
