The thickness of the ventilating panel 19 does not exceed at any point the thickness of the frame 10, with the result that the sash may be raised and lowered in its guides without interference. The edges of the plate are preferably enclosed within U-shaped metal strips 36, which strips both reinforce the plate and bring it up to the-approximate thickness of a pane of glass,

thereby permitting the use of an ordinary rubber.

glazingstrip, for both the edges of the ventilating panel and the edges of the pane of glass.

. 1, In Fig. 9 is shown a slight modification of the connection between the upper edge of the pane ofglass 18 and the lower edge of the ventilating panel 19. In this form, the crossrail 21 is omitted and the metal strip 37 which extends along the lower edge of the panel and forms a part thereof is provided with a narrow down,- wardly opening groove 38 into which the upper edge of the pane-of glass projects. The strip 37 is of approximately the same width as the groove so 7 i as j 17 about the inner periphery of the frame, and the ends of the strip project into the groove at the points where such ends meet the side stiles.

The modification shown in Fig. 10 is quite similar to that shown in Fig. 9 except that the groove 39 which is formed in the bottom of the strip 40 on the panel 19 is made sufficiently wide and deep to accommodate a rubber lining strip 41. In the modification shown in Fig. 11, the upper edge of the pane of glass 18 and the lower edge of the ventilating panel 19 extend into oppositely facing grooves 42 and 43 in a rubber sealing strip 44, which strip constitutes the sole means of connection between the pane of glass and the panel.

I claim: 1. In a ventilator, a substantially fiat metal plate having an outwardly embossed portion pro vided with louvers, a register plate in the embossed portion having openings opposite the louvers, and an interposed slide having openings for movement into and out of registration with the openings in the register plate. a

2. In a ventilator, a substantially flat metal plate having an outwardly embossed portion provided with outwardly projecting louvers, a register plate set into the embossed portion substantally flush with the surrounding flat portion of the plate to present a fiat inside surface and havingopenings opposite the louvers, and an interposed slide having openings for movement into and out of registration with the openings in the register plate.

. CARL, H. LARSON.
