But all his efforts were unavailing it became apparent that no mechanism, however perfect, could succeed so long as warps continued to be sized while a loom was stationary. In 1792 Dr Cartwright obtained his last patent for weaving machinery this provided is loom with multiple shuttle boxes for weaving checks and cross stripes. His mill was repossessed by creditors in 1793. He attempted to remedy these by: introducing a crank and eccentric wheels to actuate its batten differentially by improving its dicking mechanism by a device for stopping the loom when a shuttle failed to enter a shuttle box by preventing a shuttle from rebounding when in a box and by stretching the cloth with temples that acted automatically. He commenced to manufacture fabrics in Doncaster using these looms, and discovered many of their shortcomings. He added parts to his loom, namely a positive let-off motion, warp and weft stop motions, and sizing the warp while the loom was in action. An old man named Zach Dijkhoff assisted him in his work with creating this contraption. For a mechanically driven loom to become a commercial success, either one person would have to attend one machine, or each machine must have a greater productive capacity than one manually controlled. In 1789, he patented another loom which served as the model for later inventors to work upon. He designed his first power loom in 1784 and patented it in 1785, but it proved to be valueless. Mechanical spinning and the factory system were already in place. He addressed the problem of mechanical weaving.
