Title: **John T. Clarke: Innovator in Oriented Strand Board Technology**

Introduction

John T. Clarke is a prominent inventor based in St. Charles, IL, who has made significant contributions to the field of composite materials, particularly in the development of oriented strand board (OSB) technology. With a remarkable portfolio of 19 patents, Clarke's innovations have paved the way for advancements in the manufacturing of engineered wood products.

Latest Patents

Two of Clarke's latest patents focus on the development of a novel flat oriented strand board-fiberboard composite structure. The first patent describes a unique composite structure comprised of a baseboard with three wood strand layers. The wood strands are oriented strategically in relation to a board-forming machine. In this design, the core layer consists of strands that are oriented generally in a random direction, while the adjacent layers feature coarse and fine wood strands aligned predominantly in the machine direction. A key aspect of this invention is the specification that the coarsest strands are positioned closest to the core layer, with finer strands nearer to the outer surfaces. This structure is engineered to be free from warping, achieved through specific thicknesses of the OSB layers. The second patent builds upon this innovation by outlining an OSB product that incorporates a dry felted wood fiber overlay on one surface, further enhancing its performance and aesthetic qualities.
