Her third patent, U.S.

Patent 3,322,263, was also granted in 1966.

This patent covered an improved carrier attachment for an invalid walker — the type of wheeled or sliding walking aid used by people with mobility challenges.

The specific innovation was a tray or carrier attached to the walker that would allow users to transport objects while they used the walking aid, without requiring them to hold or carry items separately.
