Abstract
11,718. Wilkinson, T. F. June 6. Staircases. - In order to provide easier means of ascent and descent within a given limited space, as in passenger steamers, two series of steps are provided, one for each foot, each tread of one series being midway between the nearest treads of the other, and the front of each step being midway between the front band back c of the tread of the next lower step. The way is made sufficiently narrow by handrails or their equivalent to ensure the feet being placed on the proper steps. The fronts are preferably curved, as shown. Two sets of improved staircases may be combined, one for ascending and the other for descending ; or they may be combined with an ordinary staircase.
