Which machine, developed around 1764, first addressed the yarn shortage created by the Flying Shuttle?

Answer

James Hargreaves' Spinning Jenny.

Following the weaving bottleneck created by John Kay's Flying Shuttle, the critical need shifted to increasing yarn production. James Hargreaves' Spinning Jenny, emerging around 1764, provided the initial breakthrough in addressing this shortage. By employing multiple spindles vertically on a single frame, an operator could spin several threads simultaneously, moving away from the traditional one-thread-at-a-time manual process. Although the yarn produced by early Jennies was soft and weak, it successfully mitigated the immediate crisis by increasing the sheer volume of available thread.
