Latest Patents

One of Ciolli's latest patents is the "Wrap Spring Downshift Mechanism." This invention is designed for incorporation in devices such as assembly tools. The mechanism features a wrap spring that locks and releases a planetary gear speed reduction assembly, allowing for shifts between two drive ratios in response to torque throughput. The wrap spring is positioned on a drive drum within a cylindrical housing. The ends of the wrap spring are engaged by a pair of relatively rotationally adjustable and fixable spring engaging lugs. These lugs adjust the preload of the wrap spring, determining the torque level at which the spring unwraps and lifts off the drive drum, thus facilitating the shift. The wrap spring housing is coupled to the ring gear of the planetary gear assembly. When the torque applied to the wrap spring exceeds the preload, the spring unwraps, unlocking the ring gear and planetary gear assembly, resulting in a downshift to the speed reduction determined by the planetary gear assembly. An alternate embodiment of this downshift mechanism is also presented in his patent.
