Hiram Stevens Maxim - Inventions

Inventions

Maxim, a long-time sufferer from bronchitis, patented and manufactured a pocket menthol inhaler and a larger "Pipe of Peace", a steam inhaler using pine vapor, that he claimed could relieve asthma, tinnitus, hay fever and catarrh. After being criticized for applying his talents to quackery, he protested that: "it will be seen that it is a very creditable thing to invent a killing machine, and nothing less than a disgrace to invent an apparatus to prevent human suffering".

He also invented a curling iron, an apparatus for demagnetizing watches, magno-electric machines, devices to prevent the rolling of ships, eyelet and riveting machines, aircraft artillery, an aerial torpedo gun, coffee substitutes, and various oil, steam, and gas engines.

A large furniture factory had repeatedly burned down, and Maxim was consulted on how to prevent a recurrence. As a result, Maxim invented the first automatic fire sprinkler. It would douse the areas that were on fire, and it would report the fire to the fire station. Maxim was unable to sell the idea elsewhere, but when the patent expired the idea was used.

Maxim developed and installed the first electric lights in a New York City building (the Equitable Life Building (New York City) at 120 Broadway) in the late 1870s. However, he was involved in several lengthy patent disputes with Thomas Edison over his claims to the lightbulb. One of these actions regarded the incandescent bulb, for which Maxim claimed that Edison was credited by means of his better understanding of patenting law (though in England Joseph Wilson Swan had already obtained the first patent in 1878). He claimed an employee of his (Maxim's) had falsely patented the invention under his own name, and that Edison proved the employee's claim to be false, knowing that patent law would mean the invention would become public property, allowing Edison to manufacture the lightbulb without crediting Maxim as the true inventor.
