A blueprint-style technical diagram showcasing the electrical connections and development of a regulator drum. The diagram includes labeled components such as stationary fingers, motor armatures, field coils, running positions, and transition positions. It provides detailed visual documentation of the system's functioning, likely used as evidence in a patent dispute. The schematic appears to highlight the method of controlling two motors in a transit system.

This document is part of a legal exhibit from the Stanley Electric Manufacturing Company vs. Toledo Port Clinton & Lakeside Railway Company case, related to Henry Patent No. 705,241. The exhibit is labeled as Broadhurst Exhibit No. 5 and presents a technical schematic for the regulator drum connections in the Bullock Electric Manufacturing Company's control system. As a mechanical draftsman and patents expert, Lewis Latimer worked for the Edison Company on complex lawsuits in which different companies challenged each other over patent infringement. He may also have done some of this work on a freelance basis for other clients.
