Introduction
Bruce W. Bradshaw is a notable inventor based in Ludington, MI (US), recognized for his contributions to railroad maintenance technology. With a total of 4 patents, he has developed innovative solutions that enhance the efficiency and accuracy of railroad track maintenance.
Latest Patents
One of his latest patents is a maintenance vehicle and method for measuring and maintaining the level of a railroad track in a single pass. This invention features an instrument carriage, or frog, that is towed by the maintenance vehicle, maintaining a fixed relationship. The frog is equipped with at least one inclinometer to measure the longitudinal level and crossfall of the track. As the vehicle stops to perform tasks such as tamping or stoneblowing, the inclinometers are allowed the necessary settling time for accurate readings. Additionally, the method involves measuring and modeling the track prior to maintenance using a primary measurement system, followed by a second measurement while the track is being worked on.
Another significant patent is an apparatus and method for measuring the wear of railroad rail. This invention includes a carriage designed to travel along the rail's length, with the capability to move transversely in response to wear in the railhead. Fixed distance sensors on the carriage detect changes in distance to the rail, allowing for precise measurements of wear on both the top and gauge sides of the railhead.
