Abstract

669.013. Ventilators; louvre windows. GREENWOOD'S & AIRVAC VENTILATING CO., Ltd., and HUGHES, B. D. June 30, 1950, No. 16364/50. Classes 20(iii) and 137 A ventilated larder light comprises upper and lower louvre elements 8, 9, pressed out of sheet steel and secured, e.g. by welding, riveting &c. to metal uprights 1. 2, and a window frame having reinforced corner pieces 18, hinged at 21 to the uprights 1, 2, adjustment of the window 6 being carried out by a stay bar 25. A surround 5 for the window is welded to the inner sides of the uprights 1, 2 and the louvre elements 8, 9, a peripheral groove between the surround 5 and the outer members being provided to receive a corresponding flange 6<SP>3</SP> of the window frame member 6' to form a weather seal when the latter is closed. The stay bar 25 having openings 28 for adjustment on a pin 29 is loosely hinged to the frame 6, the bar 25 being capable of sideways movement when the pin 29 is extending through the enlarged opening nearest the hinge so that the end bar can engage beneath a locking member 32. The louvre elements are provided with gauges 15 at the back and draining apertures at the front. In a modification the window 6 is hinged at one side to one upright member.
