Title: Innovations of Keith Lynn Mayhood

Introduction

Keith Lynn Mayhood is a notable inventor based in Pittsburgh, PA, with a significant contribution to the field of electrical engineering. He holds four patents that showcase his innovative approach to electrical switching apparatus and circuit interrupters. His work has had a lasting impact on the industry, particularly in enhancing the functionality and safety of electrical devices.

Latest Patents

One of Mayhood's latest patents is for an electrical switching apparatus with an improved contact arm carrier. This invention features contact fingers with radial convex surfaces that are designed to seat on concave surfaces in the molded contact carrier. This design effectively transmits bending loads on the pin into the carrier. Additionally, a seal member snaps onto the end of the pivot pin, featuring fins that block the flow of arcing gases through the carrier. For lower current ratings, some contact fingers are replaced by annular spacers, which also help in transmitting bending moments and restricting gas flow. The design includes a stop ledge on the carrier that allows the center fingers to project farther toward the stationary contacts, ensuring that the arc toes on these fingers are the last to separate during operation.

Another significant patent by Mayhood is a circuit interrupter with a terminal shield and wire trough. This invention involves a molded case circuit breaker or switch that protects the LOAD and/or LINE terminals with a multifunctional terminal shield arrangement. This shield not only provides interphase barriers for the terminals and associated wiring but also includes wire channels for lower voltage supplemental wiring.
