Title: Innovations by James R. Gassen
Introduction
James R. Gassen is a notable inventor based in Charlotte, NC (US), recognized for his contributions to the field of power tools. With a total of 6 patents to his name, Gassen has made significant advancements that enhance the safety and functionality of chain saws.
Latest Patents
One of Gassen's latest inventions is the Power Tool Inertia Brake. This innovative device features an inertial-manual actuating chain brake for chain saws. It distinguishes between long-duration accelerations caused by kickback and normal operational vibrations. When a kickback impulse occurs, a spring-mass accelerometer shifts from a brake-released to a brake-applied condition, applying necessary braking torque to the saw chain. The accelerometer is activated by a pivotable hand guard, which also allows for manual operation. The design of the hand guard includes a housing and an adjustable inertia weight, enabling customization for different chain saw models.
Another significant patent is the Vibration Reducing Chain Saw Handle. This invention incorporates a resilient deflectable rear handle that connects to the chain saw housing. The cantilevered design of the rear handle allows it to absorb vibrations during operation, reducing the impact felt by the operator. The housing is strategically designed to prevent excessive deflection of the handle, ensuring both comfort and safety during use.
