Title: John M Sawyer: Innovator in Hose Structure Technology
Introduction
John M Sawyer is a notable inventor based in Cuyahoga Falls, OH (US). He has made significant contributions to the field of hose structure technology, holding a total of 4 patents. His innovative designs focus on enhancing the performance and durability of hoses used in various applications.
Latest Patents
One of Sawyer's latest patents is a hose structure resistant to pressure and vacuum, as well as kinking or collapsing. This design features a wall structure that includes elastomer embedded reinforcing cords extending in opposite hand helical patterns about the hose axis. Additionally, it incorporates a filler layer of elastomeric material that has a thickness ranging from about one-fifth to about one-fifteenth of the mean radius of the filler layer from the hose axis. The filler layer is made of high tensile modulus and hardness elastomeric material, preferably containing short length fibers dispersed throughout, oriented predominantly in the circumferential direction of the hose.
Another significant patent by Sawyer is a hose structure suitable for transporting highly abrasive media. This design consists of at least two concentric tube layers of elastomeric material. The innermost tube layer is made of a material that offers greater abrasion resistance than the layer radially outward. The outer tube layer is designed to have greater resilience than the innermost layer. Notably, the tube layers can be visually distinguishable, for example, by using different colors to serve as a wear indicator.
