Abstract
165,527. Flanagan, J. A. March 27, 1920. Sewing - machines; lock - stitching by hooks. - The needlethread loop is twisted in the formation of a lock stitch. The rotary hook is formed on a partly cylindrical and partly conical member g secured to a flange a of the hook shaft. The stationary bobbin-case holder s rides in a race formed by shoulders on the parts g, a. The bobbin-case is carried on a pin v<1> and is held in position by a spring latch which engages the groove v<11>. The loop-taking hook m passes on the left side, Fig. 4<a>, of the needle, the threadloop arm p" is detained by the usual part of the spool-case holder, and the arm p, which at first lies upon the exterior of the hook-carrying member g, finally slides off the conical surface and passes over the right face, Fig. 4a, of the bobbincase. The arm p" at the same time passes between the member g and the bobbin-case.
