2 Claims.

The invention relates to a ventilator and more especially to a window ventilator.

The primary object of the invention is the provision of a ventilatorof this character wherein the same enables ventilation to aroom'or enclosure without liability of rain sleet, or'the like, entering the room or enclosure andyat thesaine time, avoiding direct draft upon the occupants of such rooms or enclosures, the ventilator being also used as a screen for the window openingto exclude insects or the like.

Another object of the invention is the provision of a ventilator of this character wherein a slide is arranged so that the ventilator can be regulated to exclude the passage of air therethrough or to enable increased or diminished ventilation at the option of a user. I

A further object of the invention is the provision of a ventilator of this character'wherein the same involves a construction that enables the easy fitting thereof within a Window casement and also its removal therefrom, the said ventilator being of a construction to assure the proper fitting of the same in a window casement within reasonable limits of sizes thereof.

A still further object of the invention is the provision of a ventilator of this character which is simple in its construction, thoroughly reliable and efiicient in operation, strong, durable, readily and easily adjusted, and inexpensive to manufacture.

With these and other objects in view, the invention consists in the features of construction the combination and arrangement of parts as will be hereinafter fully described in detail, illustrated in the accompanying drawings, and pointed out in the claims hereunto appended.

In the accompanying drawings:

Figure 1 is an elevation of the ventilator constructed in accordance with the invention.

Figure 2 is a sectional view taken on the line 22 of Figure 1 looking in the direction of the arrows.

Figure 3 is a view similar to Figure 1 looking toward the opposite side of the ventilator and.

partly in section;

Figure 4 is an enlarged sectional view taken on the line 4-4 of Figure 1 looking in the direction of the arrows.

Figure 5 is a mutilated perspective view of one of the extensible end members of the ventilator.

Figure 6 is a perspective View of the adjustable slide for the ventilator.

Similar reference characters indicate correspending partsthroughoutjthe several views in i the drawings. i

Referring to the drawings in detail, A-designates' generally the ventilator in its entiretyand involves an open frame including end rails iii,

, bottom-rail I land top mill-I 2, respectively; these at their meeting ends being united in any suitable manner, while the innermostedg'e' of 'the bottom rail i i is formed with an outwardlyinclined or sloping'face I3 for a purpose presently described.

Fitting the end rails ii) and sli'dably telescoped thereover as well as portions adjacent thereto of i the bottom and top' rails H and i2 ar e'eixtens i've wings or end pieces it, these being preferably detail-in Figure'tiofthe drawings. 2

. 'These wings or pieces It are adjustably held engaged therewith a frame, that is to-say the end rails is thereof-,1 by screws=i5which engage in elongated slots it provided in opposite sides of the said wings or pieces it and fixed in the said frame. Counterseat'edin 'theend rails it] and concealed within the wings or pieces #4 are coiled made from sheet-metal of the shape disclosedin compression springs H which play against the closed outermost edged portions it of said wings t or pieces M so that these will be maintained under tension. In this manner through the use of the wings or pieces M the frame can be removably interfitted within a window casement or the like preferably engaged in the sash guide- Ways therein.

Arranged with relation to the open center 19 of the frame including the rails 18, H and i2,

and opposite sides thereof, preferably counter? seated at 2e, are imperforate panelstl and foraminous screen or screen cloth sections 22 respectively. The panels 21 are reversed in their positions with respect to the frame in that at the outer side thereof this panel 2! is at the uppermost half of said frame, while at the inner side of the frame the panel 2i is at the lower half thereof, which is also true with respect to the relationship of the screen sections 22 in that one 7 section thereof at the inner side of the screen is uppermost and the other section at the outer side of the screen is lowermost of the same. These panels andsections 2i and 22 at their meeting edges are overlapped and united with each other in any suitable manner as at 23 and 24 respectively. Thus, the arrangement of these'panels and'sections efiects a ventilating space 25 within the open center of the ventilator frame. The panels 2| are preferably made from cel-o-glass, although the same may be made from any other suitable material-as window pane glass, orrtransparent, or translucent material. The panels 2% and the sections 22 are made fixed by suitable fasteners 26 engaged in the frame of the ventilator.

The air from without an enclosure enters the ventilator at the outer side thereof through the lower screen section 22, thence flows within the space 25 upwardly and delivered from this space through the section 22 at the inner side of the ventilator frame and uppermost thereof. In this way direct draft upon the occupants of an enclosure or room from without will be avoided, and at the same time, maximum ventilation will be assured to the room or enclosure. or sloping face [3 of the lowermost rail l I of the ventilator frame functions as a watershed to avoid rain, sleet, or the like, from passing from without to within a room or enclosure through the said ventilator.

Arranged at the inner side of the ventilator frame are vertically disposed guides 21 for a slide 28 which constitutes a shutter or gate having a transparent or translucent center panel 29 preferably made from cel-o-glass. Now by adjustment of the slide 28 vertically of the ventilator frame to partially or completely cover the screen section 22 at the inner side of said frame, the ventilation through the ventilator can be regulated to an enclosure or. room and thus this slide28 functions as a valve for the ventilator.

The slide 28 carries finger grips 30 to enable convenient and easy operation of the slide for the regulation of the ventilator in the use thereof.

The slide 28 at opposite ends thereof has fitted therewith abutment flanges 3| coacting with the guides 21 and in this Way endwise displacement of the said slide will be avoided and, at the same time, the fitted slide through these flanges 3! will be held in a set position resultant from frictional contact of the flanges 3| with the guides 21. In other words by the flanges 3| thereon the fitted slide will move true in the guides 21 and be held frictionally in an adjusted position.

The inclined By reason of the arrangement in the structural make-up of the ventilator, the room or enclosure cannot be viewed from without the same through said ventilator, and protection to occupants in this manner will be had, yet ventilation is insured to the enclosure or room and also it will be properly screened.

The ventilator admits light to an enclosure without rendering the same dark and such ventilator can be used with or without the extension wings or pieces I4 as may be desired.

What is claimed is:

1. A ventilator of the character described comprising an open frame, tensioned extension wings 'at opposite ends thereof, and each telescopically fitted thereover, imperforate panels fitted to the frame at opposite sides thereof, one of said panels covering the uppermost half of said frame and the other panel covering the lowermost half thereof, screen cloth fitted to the frame at opposite sides thereof and disposed in inverse relationship with respect to said panels, an imperforate slide fitted to one side of the frame and movable to covering position with relation to the screen cloth at that side of said frame, and guides for the said slide and flanges on the slide for frictionally engaging the guides to hold the slide in an adjusted position.

2. A ventilator of the character described, comprising an open frame, imperforate panels fitted to the frame at opposite sides thereof, one of said panels covering the uppermost half of said frame and the other panel covering the lowermost ,half thereof, screen cloth fitted to the frame at opposite sides thereof and disposed in inverse relationship with respect to said panels, an imperforate slide fitted to one side of the frame and movable to' covering position with relation to the screen cloth at that side of said frame, guides for the said slide, and flanges on the slide for frictionally engaging the guide to hold the slide in an adjusted position.
