This topic has come up before. I checked the archive and Mr. Bilbo provided a very detailed history on standard spray and conventional sprinklers. I think the link below gets you there if not search the archive. The message was posted 27 April 2012.

I was in a building with different varieties of sprinklers and they all claim to be from 1954. There was one section with some sprinklers with the old style small deflector (in both pendent and upright) and was wondering if they made that design as late as 1954.
