Abstract

548,080. Ventilators. GREENWOOD'S & AIRVAC VENTILATING CO., Ltd., HUGHES, B. D., and FORD, E. L. April 8, 1941, No. 4678. [Class 137] A ventilator, adapted for blackout purposes and for use in the lower part of a window aperture, comprises an elongated box 1 with a central partition 5, a longitudinal air inlet 4 in its outer face, and a longitudinal outlet in its top or outer face in which is fitted a diffuser 8, a damper 11 for cutting off the air supply being provided if desired. A clip 9 may be fitted whereby the ventilator may be attached to the lower end of a blind or curtain. The diffuser may be of the form shown in Fig. la with outlet apertures 8x at its top. The ventilator may be mounted on a plate 2 with extensions 35 by which the assembly may be secured to the window frame. Means for heating filtering, medicating, or disinfecting the incoming air may be provided, and a fan may be used either to deliver air to or extract it from the interior. In Fig. 6, the central partition 16 has longitudinal slots in the centre and at the top and bottom, and the front wall is constituted by a central part 17 and parts 7x, 7 projecting from the top and bottom of the box, a flange 17x being provided for fixing purposes, and the grille or diffuser disposed in the outlet.
