John E. Randolph, an inventive mind hailing from Palatine, IL, has made significant contributions to the field of printing technology. With a total of four patents to his name, Randolph's work primarily focuses on enhancing the efficiency and functionality of printing apparatuses.

Latest Patents

Among his latest innovations, Randolph has developed a patent for a ribbon cartridge featuring a convolute-forming roller. This innovative design stores a fresh ribbon in an endless typewriter cartridge, ensuring smooth operation during printing. The ribbon is drawn from the cartridge, progressively exhausting the convolute as printing occurs. Additionally, a brake mechanism is integrated to limit the roller's motion, preventing premature unwinding of the ribbon. This invention also allows for easy rewinding of the ribbon once the cartridge is removed from the printer.

Another notable patent addresses the ribbon advancing mechanism in printing machines. Randolph's invention utilizes one-way brakes on ribbon guide rollers within the printing carriage mechanism. This clever design permits relative movement between the printing carriage and the inked ribbon, optimizing performance as the carriage moves across the paper. The return rollers are designed to rotate freely, allowing the ribbon to move seamlessly with the carriage's motion, which enhances the overall printing efficiency.
