Title: The Innovative Mind of Virgil B. Martin: A Forage Harvester Pioneer

Introduction

Virgil B. Martin, an esteemed inventor based in West Bend, Wisconsin, has made significant contributions to agricultural technology, particularly in the design of forage harvesters. With an impressive portfolio of seven patents, Martin's work stands out for its innovative approach to improving the efficiency and functionality of harvesting equipment.

Latest Patents

Among Martin's latest inventions is a cutting-edge forage harvester drive and electric control mechanism. This design is tailored for forage harvesters that are drawn and powered by tractors. The harvester features a feed roll mechanism that efficiently receives and feeds crop material to a cutterhead mechanism, which in turn facilitates the transfer of cut-up crop material to a blower for delivery to a forage wagon. Central to the operation is a main drive shaft powered by the tractor's PTO, which also drives the cutterhead and blower.

The design includes a unique drive mechanism that allows for both forward and reverse motion while incorporating a single, normally disengaged electrically engageable clutch. A solenoid-operated transmission, biased in the forward position, provides an innovative solution for seamless operation between forward and reverse modes. Additionally, the inclusion of torque sensor devices enhances safety by mechanically disconnecting driven components during overload situations.

To further improve operational efficiency, Martin has developed an advanced electrical control system, equipped with manually operable selector switches located on the tractor, catering to various modes of clutch and transmission operation. This innovative approach includes features such as automatic clutch disengagement in the event of overloads, showcasing Martin's commitment to enhancing the agricultural equipment domain.

Another noteworthy patent by Martin is a forage harvester equipped with a water injection system designed to mitigate material gumming. This mobile harvester periodically injects a controllable amount of water into the crop stream during processing, effectively preventing the buildup of troublesome gumming within the equipment.
