Title: Marvin D Johns: Innovator in Clutch and Coupling Technologies
Introduction
Marvin D Johns is a notable inventor based in Fort Wayne, Indiana, recognized for his contributions to clutch and coupling technologies. With a total of two patents to his name, he has made significant advancements in the field of mechanical engineering.
Latest Patents
One of Johns' latest patents is the "Air Pressure Loaded Clutch." This invention features a self-contained hydraulic unit designed to control the operation of a friction clutch assembly. The hydraulic unit connects to a pressure source, allowing it to actuate multiple levers to engage the clutch when pressure is applied. Upon pressure removal, spring mechanisms withdraw the levers, disengaging the clutch. The hydraulic unit is non-rotatably supported by the friction clutch assembly and includes both an axially fixed member and an axially movable member interconnected by a sliding connection. A piston and diaphragm arrangement between these members enables the engagement of the clutch through the application of pressure.
Another significant patent is the "Belleville Damper for Torque Transmitting Coupling Device." This invention provides an improved resilient means between cooperating rotary elements of a coupling device, enhancing the torque capacity of the unit. The resilient means consists of a Belleville stack located in aligned pockets within the rotary elements. The operational stability of the Belleville stack is increased by suitable guide means, which also allow for the stack to be a self-contained and easily replaceable assembly.
