John M Berger

Title: John M. Berger: Inventor of Specialized Sealing and Shaft-Coupling Apparatus

Introduction

John M. Berger is an inventor associated with Muncie, Indiana, and Maxon Corporation. His work includes inventions addressing valve-follower sealing and the transmission of force between misaligned reciprocating shafts. He holds 2 patents.

Latest Patents

Berger’s listed patents include two mechanical apparatus designs.

- Pre-loaded valve follower sealing apparatus. This invention uses a follower ring and flange insert assembly containing a preload and sealing element between two hollow cylinders. The element has a concave fluid-contacting surface when uncompressed, which becomes substantially cylindrical under compression.

- Multi-functional reciprocating shaft coupling apparatus. This coupling transmits force between shafts whose longitudinal axes may be misaligned. It uses a compound collar and force-transmitting washer assembly, with washer layers made from materials that differ in composition or hardness. The design aims to reduce cold flow and self-adhesion that could otherwise cause the layers to bind over time.

Career Highlights

Berger’s listed inventions focus on practical mechanical challenges: maintaining a seal in a valve-follower assembly and transmitting force reliably between misaligned shafts. His work is associated with Maxon Corporation.
