Title: The Innovations of John W. Murphy

Introduction

John W. Murphy is a notable inventor based in Waukegan, Illinois, recognized for his contributions to the field of mechanical engineering. With a total of eight patents to his name, Murphy has made significant advancements in the design and functionality of brake lathes.

Latest Patents

One of his latest patents is a brake lathe designed for both drum and disc rotor brakes. This innovative lathe is engineered to grind the inside cylindrical surface of a brake drum while machining the opposite parallel surfaces of a disc rotor. The design features a rotating spindle output shaft that extends along the axis of the lathe housing. A motor drives the spindle, translating an endless belt over a V-belt pulley. The arrangement includes a pair of cog belts that connect an intermediate pulley to the V-belt pulley and a taper lock bushing mounted on the spindle shaft. This configuration effectively reduces the motor speed to the desired spindle output speed, eliminating the need for an idler shaft. The lathe also incorporates a first cross-feed slide that advances the inboard and outboard cutters toward and away from the disc rotor's surfaces. Additionally, a second cross-feed slide is adjustable from the first side of the housing, allowing the operator to adjust the depth of cut without leaning over the axis of the housing.
