Abstract

497,029. Ventilators. MUSGRAVE, J. L., and CRITTALL & CO., Ltd., R. June 11, 1937, No. 16221. [Class 137] A ventilator fitting comprises a number of flat multi-sided plates spaced apart vertically and each having an opening, the external dimensions of one plate being approximately equal to the dimensions of the opening in the plate or duct next above it. Figs. 1 and 2 show a number of spaced apertured plates a of triangular form supported by midfeathers b from a member d which fits into the mouth of an air duct. In modifications, the plates may be square, rectangular, or hexagonal in shape. Figs. 7 and 8 show one square, and four rectangular plates. By varying the size of the openings in each plate relative to the external dimensions of the succeeding plate below it, the direction of the discharge from, or inflow of air to the ventilator may be varied, and an inflow caused to the spaces between the lower plates, while an outflow takes place between the upper plates.
