Application lied Iarch 29, 1922. Serial No. 547,642.

To all whom it may conce-m.

Be it known that I, HEARD Rnsrnss, a citizen of the United States, and resident of the borough of Manhattan, city of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in ventilators, of which the followin is a specification.

This invention re ates to ventilators.' The object of the invention is the production of an'adjustable ventilator, that can be located and'secured in place in window frames or other openings of various widths. A. second object is to rovide a ventilator, through f) air can be obtained, but which prevent rain, sleet, snow, insects and the like to pass therethrough.

The organization of the invention comprises a plate with openings that are4 protected by hoods. A screen is secured to the inner face of the plate and covers the openings therein. Extension members are slidably connected to the plate of the ventilator, to enable it to be connected to window frames or other openings-of various widths.

The accompanying drawings exemplify one form of the invention and in which Fig..

1 represents an inside elevation of a window frame, with the improved ventilator connected'thereto, both having portions. thereof broken away; Fig. 2 shows an outside elevation of the ventilator; Fig. 3 indicates a section of Fig. 1 on the line 3, 3; Fig. 4 is a section of Fig. 1 on the line 4, 4; Fig.v 5

indicates an enlarged fragmentary portion of Fig. 4; and 6 shows an enlarged fragmentary portion of Fig. 3.

A fragmentary portion of a window frame is indicated with the side members 20, the horizontal member 21, and the sash 22.

The ventilator com rises the outer reetangular plate 25, whic has guards stamped therefrom bulging outwardly formingthe ventilating o nings 26 with the protecting hoods 27.` e roofs of the latter are curved at their sides 28 and at their front portions 29. An opening 30 is indicated at the bottom of each hood. The openings 26 are in parallel rows, with the openings of one row above the corresponding openings of the other row. The openings of one row may, however, break joints with the openings of the next adjacent row. The said openings are preferably made by pressing y ing flanges.

out the material of the .plate 25, the hoods resulting from the process of manufacture.

A horizontal U-shaped inwardly extend-` ing upper normally horizontal flange 35 and a similar U-shaped inwardly extending lower normall horizontal flange 36 are formed with t e plate 25 to providehold- At the opposite ends of the plate 25 are formed the similar inwardly extending U-shaped fianges 37 and 38..

A fiy screen 40 is encased by a frame having at its upper and lower edges respectively the similar U.shaped fianges 41 and at its ends by the similar Uv-shaped flanges 43. The screen 40 is adiacent to the inner face of the plate 25 and covers the openings 26.

The flanges 41 bear against the inner face of the plate 25 andthe flanges 43 are encased by the fianges 37 and 38.

On the opposite ends of the plate 25 are shown the similar extension members or end pieces 45. Each of the members 45 has formed therewith the curved cut-out portion 47, the upper flange 48, the similar lower fiange l49 and the -side U shaped end flanges 50 with the openings 51. Angle shaped adjusting anges extend from the members 45. The said members 45 are slidable and spaced from the fiy screen 4() to prevent them contacting therewith, The flange 48 engages the flange 35 and the flange 49 engages the flange 36.

To use the ventilator it is located in a window frame or other opening and if 1u the former above or below a sash thereof.

The extension members 45 are located with their end flanges 50 bearing against the adjacent Side membersof the window frame arranged upon the inner side of the plate and carrying a ily screen, said frame having its ends held within the holding flanges, guide flanges formed integral with the top and bottom ofthe plate, and end pieces having slidable engagement with said guide Hanges and being adjustable longitudinally of said plate, said end pieces being spaced from the fly screen by the in- IU wardly bent portions of the holding flanges which serve to keep the end pieces from contacting with the fly screen and thereby protect said ily screen from being scraped when the end pieces are bein adjusted.

Signed at the borough of of New York, in the county of New Yorc and State of New York this 9th day of March A. D. 1922.
