Title: Mark D. Lincoln and Razor-Blade Cleaning Innovations.

Introduction

Mark D. Lincoln is an inventor associated with Taunton, Massachusetts, and The Gillette Company. His patent work includes methods and equipment for cleaning stacked razor blades during manufacturing. He is credited with 3 patents.

Latest Patents

Lincoln’s listed patent, “Aqueous Cleaning of Blade Stack,” describes equipment for removing oil, dirt, and grinding debris from metal surfaces. The machine moves stacks of razor blades through separate wash, rinse, and drying stations designed to limit contamination between stages. The blades are mounted on rods held by a fixture, while carefully directed water or air jets cause the blades to riffle, helping expose their surfaces to cleaning.

The patent also describes using purified water for rinsing and, preferably, an aqueous cleaning solution for washing. A circulation system moves these materials through the stations to support efficient use. The related method applies the same staged cleaning approach to razor-blade manufacturing.

Career Highlights

Lincoln’s patent work addresses a practical manufacturing challenge: cleaning closely stacked blades thoroughly while controlling contamination and the use of cleaning materials. His association with The Gillette Company places this work in the context of razor and blade production.

Collaborations

John F. Krantz and Manohar S. Grewal are identified as Lincoln’s coworkers. The available information does not specify their roles in the listed patent work.

Conclusion

Mark D. Lincoln’s documented inventions focus on aqueous cleaning equipment and methods for stacked razor blades, combining staged processing, directed fluid flow, and recirculation to support manufacturing.
