While the Dormitzers were rich enough that they could afford to hire servants to do household tasks such as cleaning windows, Anna Dormitzer was sensitive to the precarious dangers of cleaning, particularly window-cleaning so much so that starting in 1878, she registered twelve patents for a variety of window washing devices. These included chairs and stepladders and a combination of both. Dormitzer included very precise and detailed drawings with her applications since all but her first application included a model. • Window-Cleaning Step-Chair, Aug. 13, 1878 • Window-Cleaning Chair, Sept. 2, 1878 • Window-Cleaning Chair, July 12, 1881 • Combined Window Cleaning Chair and Fire Escape, Apr. 18, 1882 • Window Cleaning Chair, Feb. 12, 1884 • Window Cleaning Chair, June 9, 1885 • Window Cleaning Chair, Feb. 2, 1886 • Ornamental Step Ladder, Feb. 16, 1886 • Paint and Brush Bucket, May 25, 1886 • Safety Watch Pocket, Mar. 27, 1888 • Step Ladder, Feb. 25, 1890 • Step Ladder, Apr. 7, 1891 • Ornamental Step Ladder, Jan. 3, 1893 • Chair for Washing Windows, May 30, 1893 • Napkin Holder, Sept. 24, 1895 • Napkin Holder, May 5, 1896 == Death and legacy ==
