Gasproof Canary Carrier (Feb, 1940)

Gasproof Canary Carrier
Canary birds kept as pets by one Englishwoman would be protected from gas attacks by means of a novel pushcart while she sought safety in a gasproof chamber. Air from a pump operated by one wheel of the cart enters the glass cage through a gas filter as the wheel turns. If the cart is stationary, the wheel may be turned by hand.

    Considering the traditional role of the canary in mines, this is incredibly ironic.

    That’s exactly why I posted it :)
