Back in 1922 a woman named Emma Read from Spokane, Washington patented a baby cage that was designed for women with children in houses without backyards or gardens for them to play in.
Suspended from the side of a building, the baby would have access to fresh air and sunlight through the cage’s wire frame, and still have sufficient room to play with toys, according to the patent. The patent also notes that the cage could double as a place to sleep, with removable curtains working to prevent a draft.
“It is well known that a great many difficulties rise in raising and properly housing babies and small children in crowded cities, that is to say from the health viewpoint,” the patent reads. “With these facts in view it is the purpose of the present invention to provide an article of manufacture for babies and young children, to be suspended upon the exterior of a building adjacent an open window, wherein the baby or young child may be placed.”
