Abstract

13,715. Edwards, W. June 19. Ventilators.-A ventilator consists of a metal box b, fixed in an opening of the outer wall a near the ceiling, containing a loose inner box c, to the inclined end d of which the mica or metal valve e is hinged. Air passes from the room through a grid and opening past the bottom of the flap e, and out, as shown by the arrows. Any inrush of outside air is checked by the plate l, and is then guided by the inclined sides n of the box c, Fig. 3, to the valve e. The valve can be kept upon its seat by the leverf actuated by the cord g, the spring h serving to restore it to its original position.
