Title: The Innovative Contributions of Robert W. MacWilliams
Introduction
Robert W. MacWilliams is a notable inventor based in Springfield, MA (US). He has made significant contributions to the field of firearms technology, holding 2 patents that showcase his innovative spirit and technical expertise. His work has focused on improving the functionality and accuracy of revolvers, making them more efficient and reliable.
Latest Patents
One of MacWilliams' latest patents is the Ratchetless Gun, which introduces a novel indexing system for revolvers. This system features a trigger-actuated finger that grabs one of several circumferentially-spaced notches on the rim of the chambered cylinder. As the trigger is pulled, the cylinder rotates through the required arc to advance the next chamber to its proper firing position. The finger is part of a modular unit that fits into a complementary recess of the revolver's frame, replacing the standard 'hand-and-ratchet' combination. This module also includes a stop for precisely registering the rotated chamber with the revolver's barrel just before firing.
Another significant patent is related to an improved firearm design. This design features a cylinder and barrel configuration that reduces the stress imposed on the throat of a revolver barrel. This improvement enhances both the strength and accuracy of the combination. The design allows for some degree of bullet sizing directly in the cylinder, which permits a smaller barrel bore and decreases the jump distance from the cylinder to the barrel. This bullet sizing occurs at a lower velocity and over a greater distance, resulting in better accuracy and increased barrel strength.
