available, culminating with an 1898 patent no. 606,795 and this is what Westinghouse needed to form a case for patent infringement of their earlier Shallenberger AC meter. After eight years of litigation, Westinghouse and his army of lawyers won the final judgement, exhausting what
The wattmeter After the businesses in Pittsfield started falling through, he pulled back to Great Barrington, where his work on transformers started. He began the Stanley Instrument Company, selling transformers and measuring equipment, and they developed a new invention, the watt- hour meter. This meter was able to consider both the voltage at any given time, along with the current, giving a precise measurement of power usage in watt-hours. Another key to this innovation was found when the bearings used for the rotating disc used to measure
The watt-hour meter patent used two coils. One for measuring current and the other for measuring voltage.
Stanley Bottle Company In 1913, William Stanley invented the all-steel, double-wall vacuum bottle and named it after himself. Pulling from his earlier experience with nickle plating and pulling a vacuum from light bulbs. The brilliance is that if you remove the air between two conductors of heat, the energy from one side, doesn’t travel through the vacuum in the middle, insulating the material on the inside from the ambient environment outside.

bearing altogether and use magnets to suspend the coil and disc for the most precise usage measurements
