Abstract

2741. Richards, F. G. Feb. 5. Window opening and closing apparatus. -- To enable windows, fitted in the clerestory roof of railway carriages, to be opened in the direction most suitable for ventilation, the light c is hinged at c' to an intermediate frame b which is hinged at b<1> to the main frame a. An operating-rod e', working in brackets e fixed to the roof of the vehicle, carries two slotted plates f, g, in one f of which slides a pin d<1> attached to an arm d secured to the frame b, and in the other g a frame d<3> attached to an arm d' secured to the light c. When the operating-rod is moved from its mid-position, in which light and frame are both closed, in one direction, the intermediate frame b opens as shown in Fig. 4, the light remaining closed in the frame. A similar movement in the opposite direction opens the window light c, while the frame b remains closed. The slots in the plates f, g are continued at f<3>, g<3> a short distance parallel to the operating- rod, to prevent the window from slipping back into the closed position. In a modification, shown in Fig. 7, the arms d, d<2> are replaced by slotted plates, in which work pins attached to arms secured to the operating-rod.
