Grinnell got a patent for his version of the sprinkler system. It caused the valve and its seat to move outwards simultaneously until the solder joint was completely severed. The flexible diaphragm had a further and most important function. By this means the valve seat was forced against the valve by the water pressure, producing a self-closing action, so that the greater the water pressure, the tighter the valve. He increased sensitiveness by removing the fusible joint from all contact with the water, and, by the ingenious method of seating a valve in the center of a flexible diaphragm, he relieved the low fusing soldered joint of the strain of water pressure. Even though he put tremendous effort and time into educating the masses on his sprinkler system, by 1883 only about 10 factories were protected by the Parmelee sprinkler.īack in the U.S., Fredrick Grinnell, who was manufacturing the Parmelee sprinkler, designed a newer and more effective version which became known as the Grinnell sprinkler. They had a policy of encouraging risk improvement and more particularly the use of the most up-to-date and scientific apparatus for extinguishing fires. This company was founded in 1870 by the Textile Manufacturers' Associations of Lancashire and Yorkshire as a protest against high insurance rates. He found this influence in James North Lane, the Manager of the Mutual Fire Insurance Corporation of Manchester. John Butler of the same town.Īlthough he got a contract through his efforts, the Bolton Cotton Trades Mutual Insurance Company was not a very big company outside of its local area. The Directors of this Company and more particularly its Secretary, the late Peter Kevan, took an interest in Parmelee’s early experiments, and eventually it was to Major Hesketh, its Chairman, that Parmelee owed his first order for the Sprinkler Installations which were installed in the Cotton Spinning Mills of John Stones & Company, at Astley Bridge, Bolton, to be followed soon afterwards by the Alexandra Mills belonging to Mr. The first of these was Major Hesketh, who, in addition to being a cotton spinner in a large business in Bolton, was Chairman of the Bolton Cotton Trades Mutual Insurance Company. In this connection he was fortunate enough to enlist the sympathies of two men, who both had connections in the insurance industry.

He knew that he could never succeed in obtaining contracts from the business owners to install his system unless he could at the same time ensure for them a reasonable return in the shape of reduced premiums. He talked about how the sprinkler system would reduce the loss ratio, thus saving money for the insurance companies. Once Parmelee realized this, he turned his efforts on educating the insurance companies about his system. Most people could not afford to install a sprinkler system. His invention did not get as much attention as he had planned. He then traveled to Europe to show people that there was finally a way to help stop a building fire before everything was destroyed. Parmelee called his invention the "automatic fire extinguisher". Parmelee patented his idea and had great success with it in the U.S. Parmelee invented the closed head sprinkler in response to exhorbatabtly high insurance rates. At the time he was the president of piano company. Parmelee of New Haven, CT created and installed the first closed head fire sprinkler in 1874 to protect The Mathusek Piano Works.
