Title: D Max Harshbarger: Innovator in Fire Safety Technology
Introduction
D Max Harshbarger is a notable inventor based in Hudson, WI (US), recognized for his contributions to fire safety technology. He holds 2 patents that showcase his innovative approach to enhancing fire prevention measures in electrical installations.
Latest Patents
One of Harshbarger's latest patents is the "Fire stopping cover plate for fire stopping electrical outlets and switches." This invention features a fire stopping faceplate assembly designed for electrical boxes. The assembly includes a faceplate with an inner surface and a fire stopping mat positioned adjacent to it. The fire stopping mat serves as an active system that creates a fire barrier, effectively preventing temperature rise on the wall side opposite the fire. It achieves this by utilizing an endothermic material that withdraws heat and expands to provide additional insulation, thereby stopping the spread of fire. The mat may incorporate an intumescent compound, an endothermic compound, or both, along with a layer of infrared blocking material made from metal or ceramic fiber.
Another significant patent is the "Low density fire barrier material and method of making." This invention pertains to a fire barrier material that consists of at least 25 weight % binder, 10 weight % intumescent compound, and 5 weight % organic fibers with pendant hydroxyl groups. The density of this fire barrier material ranges from greater than zero to about 0.35 grams/cm³. The patent also outlines a method for producing this innovative fire barrier material.
