Inside of the Grinnell Automatic Sprinklers box

I found a Grinnell Automatics Sprinklers box, complete with the sprinkler and wrench. It was back in 2007, when I was hired to do an interior demolition in Greenpoint, Brooklyn. The DiMola Bros crew and I had to dismantle the masonry and wood frame walls of an old manufacturing building. The building used to produce injection molds for plastic caps (like the kind you find on a soda bottle).

The man who hired me for the interior demolition had just purchased the building, which was 10,000 square feet, and was planning on dividing it into three rental units. That meant that any remaining rubbish or debris had to be removed, and several of the walls had to be torn down.
I focused on the job, knocking down wall after wall, until I saw this Grinnell Automatics Sprinklers box. It was hanging by a single nail. Now, it hangs outside of my office.

Although Henry S. Permalee patented the first ever sprinkler device, Frederick Grinnell immensely improved the design. In 1881, he patented his own sprinkler, known as the “first sensitive sprinkler.” In order to improve Permalee’s design, Grinnell addressed thermal sensitivity, prevention of clogging, leak tightness, and “the necessity for completely rupturing the solder joint before any water could escape to cool the solder,” according to research by the American Society of Plumbing Engineers.
