Walker, of Malden, Massachusetts, in 1900 and issued November 26, 1901, as patent no. 687705. A popular hand-cranked glass, aluminum, and screen window combination was later designed by American engineer Van Ellis Huff and found widespread use in temperate climates before the advent of air-conditioning.
