Fredrick Grinnell

Managing Real Estate Broker with Fathom Realty PB00068179

Frederick Grinnell was born in New Bedford, Massachusetts back in 1836.  I have no clue as to his parents, or much of anything until he graduated from the Rensselaer Polytechnic Institute in 1855.  After graduation, he worked as a draftsman, construction engineer and manager for several railroad companies.

In 1881, he patented a device that is still in use to this day.  in 1892, he started his own company the General Fire Extinguisher Co., in Providence, R.I.  that company has been sold to several others companies throughout the years. During his lifetime, he secured 40 patents on the improvement of the first automatic sprinkler system by using a glass disc. Almost all of the automatic sprinkler systems bears his name.  the company is owned now by Simplex.

Hello James - an important invention.  I was thinking it came along much later than you explained in this post.

Good morning James,

I have seen a few of them and had no idea of the name!

There is a restaurant named Grinnel's with great steaks here!

Make yourself an astonishing day.

I often wondered what triggered those sprinklers James Dray . A thin glass disk makes perfect sense.

Something we take for sprinklers.

Fire sprinklers are required in all new homes or majorly remodeled homes in our area.
