Manual Bellow Air Pump, Fire Siren/Fog Horn, Siebe Gorman & Co. Ltd, 1880
SIEBE GORMAN & Co Ltd of London, Manual Bellow Air Pump System, circa 1880. This is a foot operated air supply pump for either a Deep Sea Diving Helmet or Firefighters Smoke Helmet. Instruction plate on this specific item indicates it was used for Firefighters. This is an original air pump used to pump fresh air into the safety helmet using the double bellow system operation.
Into the 1900's more advanced and efficient methods, which included oxygen tanks etc., forced such antiquated machines out of the market. With this, it is important to note that the Siebel Gorman Company added the large brass horn to the bellow pump and sold it as a Fire Siren or Fog Horn for maritime sailors and fishermen to sound out to approaching ships, or to alert sailors of on board dangers.
