June B Horne invented an emergency escape apparatus and method of using same, and received patent #4,498,557 on 2/12/1985.

June B Horne wrote in the patent abstract: The emergency escape apparatus includes a slide device installed at a staircase, and includes a slide member extending at an incline over the stairs when disposed in its use position. In order to use the apparatus, the slide member swings about a hinge device connected at one side edge of the slide member between an upward storage position adjacent to the railing or the like and the incline use position over the stairs. Mounting devices fix the slide member to the staircase, and a latching device maintains the slide member in its upright storage position in a releasable manner.
