The Griswold “Burglar Alarm”

The Griswold “Burglar Alarm”

Griswold made much more than just a line of cookware. Did you know that Griswold also made, and held the patent for, a burglar Alarm? I didn’t think so. Inventors John Harvey and David Shields, assigned to Matthew Griswold. Application March 1, 1893. Patent granted Feb. 27, 1894. #515,677.

This burglar alarm was designed to be screwed into a door casing. If an unannounced person were to open the door when the alarm was set, it would cause a blank cartridge to explode.

That would be a very nasty surprise for the would-be burglar.

I’ve seen two of the Griswold burglar alarms – both in the collection of Larry and Marg O’Neill of Tacoma, Washington. Larry and Marg even had the wood pieces from the door casings into which the alarms were screwed!
