The Inventions and Ideas of Sakichi Toyoda: Overview of Sakichi Toyoda's Inventions

Although Sakichi Toyoda attained a patent for his wooden hand loom, his ultimate aim was to design a power loom.
The Inventions and Ideas of Sakichi Toyoda: Overview of Sakichi Toyoda's Inventions
The first power loom invented in Japan was the device awarded patent No. 3173 "Loom" in August 1898. The Toyoda Power Loom, based on this patent, was a wood-iron composite power loom which featured a wooden frame combined with iron gears and shafts in the power transmission mechanism.
During his lifetime, Sakichi was awarded a total of 45 industrial property rights, including 40 patents and five utility model rights. Furthermore, he filed eight of his Japanese patents in 19 countries outside Japan, obtaining 62 overseas patents in total1, including a circular loom2, a thread reeler and automatic stoppage device3, and an automatic shuttle changing mechanism (push-up mechanism).4

Of the 45 industrial property rights awarded to Sakichi, 38-the majority-were looms or loom-related mechanisms. Of his other inventions, four were devices related to fabric preparation, including a yarn-winding machine and a weft winding machine, while three were related to a circular single flow motor (rotary steam engine).
