Title: Roger A. Finnamore: Innovator in Locomotive Technology

Introduction

Roger A. Finnamore, an inventor based in Quincy, Illinois, is recognized for his innovative contributions to locomotive technology. With a total of two patents to his name, his work primarily focuses on enhancing the efficiency and functionality of air compressors used in locomotives.

Latest Patents

Finnamore's notable patent is for a "Locomotive Air Compressor with Outboard Support Bearing." This invention introduces a locomotive air compressor that features a detachable bearing housing containing an outboard crankshaft bearing. The innovative design of the bearing housing includes a flange, a tapered housing, and a bearing retainer, effectively streamlining the functionality of the air compressor.

The central bore allows for the passage of the crankshaft, while an annular recess supports the outboard crankshaft bearing. This outboard crankshaft support enables positioning closer to the electric motor, minimizing the deflections typically associated with prolonged, unsupported crankshafts. By eliminating these deflections, Finnamore's design supports the adoption of more efficient electric motors that can operate with a smaller air gap between the rotor and the stator. Additionally, the detachable nature of the bearing housing allows for easier access and servicing of the bearings in the crankcase.
