The Canary Resuscitator

Cage for reviving canary, with oxygen cylinder, made by Siebe Gorman & Co. Ltd, London.

Canaries were used in mines to detect deadly gases, such as carbon monoxide,  because canaries are much more sensitive to small amounts of the gas and reacted to it before it could harm humans. This cage was used. Once a canary showed signs of carbon monoxide poisoning the door would be closed and a valve opened, allowing oxygen from the tank on top to be released and revive the bird. The oxygen was employed because many miners enjoyed the canaries and did not want to lose their companionship.
