The invention is a specialized hand tool with an electrical connection point at the midpoint of the driver shaft. This provides continuous and uninterrupted electrical continuity during the testing of railroad relays.
Inventor Roy E. Weir of Milford, MA has designed a specialized hand tool with an electrical connection point at the midpoint of the driver shaft.
As anyone who performs a lot of mechanical work will attest, nothing beats having the proper tool for a job. The proper tool can save time and money, produces a higher quality job, reduce damage to equipment, and provide for the increased safety of the worker. Each field of mechanical work has its own type of specialty tools, each performing a specialized task. One such task performed by technicians working on railroad signaling and/or control equipment is that of relay maintenance. Such maintenance often requires the user to loosen e-nuts while maintaining electrical continuity with the circuit. Workers often hook electrical leads to the shaft of the tool such that continuity is maintained. However, as the tool is turned, the electrical lead is prone to falling off, causing reading error or perhaps even delays in train operations. Inventor Weir has created a means by which electrical continuity when accessing e-nuts one railroad relays can be ensured.
This clever new invention prevents control error and train delays. It is designed specifically to tighten and loosen e-nuts; therefore, has copper construction and a plastic ergonomic handle. The use of the Railroad Current Testing E-Wrench allows one to perform maintenance on railroad relays in a manner which is not only quick, easy and effective, but ensures electrical continuity as well.
