(Cl. 98-99)
This invention relates to improvements in ven
tilators. It is an object of the invention to pro~
vide. a ventilator including ka downwardly and out
wardly inclined deiiector plate spaced above the
bottom of a window frame opening and secured
therein so that a sash may rest upon the said
plate 9 made either in one piece as shown in
Figures l and 2, or in two pieces as shown in
Figures 3, 5 and 6, and two supports l0 on which
the opposite extremities of the defiector plate are
secured. When the deilector plate is made in
two pieces they are both of substantially the same
deñector plate to allow fresh air to flow inwardly
