Having thus fully described my invention, What I claim as new, and desire to secure by Letters Patent, is-

1. An adjustable ventilator of the class described comprising a plate provided with a circular orifice, a perforated bracket secured to said plate and extending across said orifice, and provided with reversely arranged integral inclined planes 10 10, in combination with a disk adapted to close said orifice and formed with an integral shank and plate 17 formed with oppositely-disposed radial shoulders 19 19 having reversely-beveled edges 2O 20, adapted to pass through said perforation and engage said inclined planes on the bracket to removably secure said disk in the orifice detachable disk 12 formed with the converging edges 14 14 and annular iange 15, and the integral shank 1G and rectangular plate 17 provided with the projecting lip 1S, and reversely-beveled edges 2O 2O substantially as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
