Abstract

215,512. Bean, T. R. March 21, 1923. Pivoted-window opening and closing apparatus. -A number of greenhouse &c. lights are operated by a screw- and-nut operated longitudinal rod F, bell-crank lever E and vertical rod pivoted to the window and to the bellcrank. The operating mechanism L, H, J is carried on a bracket G and the nut J is connected to the movable rod by links K.
