PORTABLE G 0m or inal application and m n 19,1928, Serial no. 202,000. Divided and um application man 1a,.

This invention relates' to ventilating apparatus, and has reference more particularly to ventilating appliances of aportable char-. .acter which are adapted for a plication to ithe windows of residences and 0t er buildings to expel foul air from the interior :or inducefresh air from the outside, without involving any substantial alterationor defacement of the window structure.

In an ap lication heretofore filed by me on the 19th dhy of March, 1928, Serial 262,608, of which this application-forms a 'vision, I have disclosed and claimed certain features of the ventilating equipment herein disclosed, comprising a panel adapted tobe mounted op-- posite a window and formed with an o ening,

' a :fan motor and fan mounted on sai panel over said opening, and a pair of brackets -"adapted to be attached respectively to mem- "20 bers of the window frame with each of the brackets so formed as to engage and hold the panel at both the upper and lower edges of the latter and in combination therewith an extensible telescoping closure strip hinged at it's forward edge to the lower edge of the panel and at its rear free edge adapted to rest on the'top of the, upper sash when the latter is in -lowered position; the inner telescoping member of said closure strip bein provided on its free edgewith a spacer ri mg on the outer face of the up r sash as the latteris raised and lowered in order to prevent the free edge of the closure strip from striking the to cross bar of the sash as the'latter is being owered.

According to my present invention, I provide on each side of the upper sash a pair of de nding push and pull rods, for raising an lowering the upper sash without havin to first remove the panel and these push and pull rods also serve the additional function of guides and spacers for the free edge of the closure strip preventing any interference of the latter with the tcp stile of the upper sash as the latter is being lowered. 1

In the accompanym drawings illustrating the practical and "pre erred embodiment of the resent invention- Fig. 1 is a front elevation of a WlIldOW frame showing the upper sash lowered and my. improved ventilating outfit applied thereto. v

, Fi' 2 is a vertical transverse section showin t e upper sash in raised position.

I g. 3 1s a vertical transverse section showing the upper sash in lowered position and the free edge of the closure strip resting on .the upper cross bar thereof.

Fig. 4 is .a vertical section, broken out, in the plane of one of the panel supporting stri s. ig. 5 is an enlarged perspective detail of the extensible'closure strip, showing the under side thereof.

Fig. 6 is a perspective detail of one of a pair 'of push and pull rods which serve for raising and lowering the upper sash and also as trackways for the free edge of the closure strip.

Fig. 7 is a perspective detail of a bracket detachably engaged by the push and pull rods shown in Fig. 6.

Referring to the drawings 10 designates the'top bar and 11 the side bars of a conventional window frame, and 12' and 13 designate 75 tively the upper and lower window sashes. 14 designates a rectangular panel conveniently made of wood and formed with a central hole 14 in which is mounted an annular frame member 15 formed with radial arms 16 and a ring 17 in which is supported an electric'motor 18 operating a direct driven ventilating fan 19 which serves-to move air through the ring frame 15 when theupper sash 12 is lowered aslshown in Fig. 3.

The panel 14 is supported in working position by means of a pair of metal strips 20 formed on their lower ends with upturned hooks 21 that support the lower edge of the panel, as clearly shown'in Fi 4, and on their upper ends with downturn hooks 22 which overlap the upper edge of the panel. The downturned llmb of the hook 22 is formed with an upwardly turned or re-entrant terminal portion 22' that bears against the outer "face of the panel 14, and the downturned portion of the hook has a tap opening to 7 receive a thumb screw 23 whic bears against the upturnedor re-entrant portion 22. and forces the latter tightly against the panel.

By this means the upper portion of the panel is heldtightly against the window frame, and by retracting the thumb screw 23 the panel may be readily entered endwise into, and withdrawn from, its supporting brackets in an obvious manner.

When the up er sash is lowered, as shown in Fig. 3, in or er to enable the fan to functionefliciently it is desirable to close the open ing between the lower edge of the panel and the top of the lowered sash. The panel 14; in practice is made wide enough to serve the widest window of any dwelling or room in which it may be used, and when applied to a narrower window, can overhang the sideframe members of the latter, if necessary,

without interfering with its proper func-' tioning. The closure strip, however, must be adjustable lengthwise to fit the width of the particular sash with which it cooperates, and for this purpose the closure strip consists preferably, as best shown in Fig. 5, of a sheet and the member or members 28 and the main member 24: are so adjusted that their combined length will equal the width between the sash grooves of the upper sash 12.

When employing a ventilating panel of this character which, when in place, covers the major portion of the upper window sash, it is desirable to provide means for conveniently raising and lowering the upper sash without having to first remove the panel. As a convenient means for this purpose I preferably employ on each side of the upper sash a pairof push and pull rods 30. The upper end of each rod is bent to form-a hook 31 adapted to detachably engage with a horizontal U-shaped bracket 32 mounted on the upper end of each sash stile, as shown in Figs. 1, 2 and 3. The vertical limb of the bracket and its upper horizontal limb are provided with

holes

33 and 34 respectively (Fig. 6) through which the hook 31 may be successivelyentered, as clearly shown in Fig. 2. The rod 30,111 the closed position of the upper sash, depends somewhat below the lower edge of the panel, as shown in Fig. 2, and may be formed on its lower end with a ring 35 convenientiy engaged by the linger. By reference to ig. 2 it will be observed that the free edges of the extensions 28 oil the closure strip ride on the rods 3i), thus spacing the free edge of the closure strip the stiles of the up per sash, preventing any scratching or marring of the surface finish of the latter and also serving to prevent collision of the free edge of the closure strip with the top bar of the upper sash when lowering the latter. During the lowering of the upper sash the free edge of the closure strip rides on thepush and pull rods 30 as shown in Fig. 2, and, as the upper sash reaches its fully lowered position shown in Fig. 3, the free edge of the closure strip rides off the upper ends of the rods 30 and comes to rest on the top cross bar of the lowered sash, in the manner clearly shown in Fig. 3.

In the case of the extensible closure strip herein shown, wherein the extension members 28 are mounted in the

guide flanges

25 and 26, the pull rods prevent flange 26 (which is somewhat narrower than the upper sash) from striking against the lower edge of the top stile of the upper sash during the lowering of the latter. However, where a single or unitary closure strip may be employed, the push and pull rods 30 maintain the free edge of the closure strip out of contact with the stiles of the upper sash, preventing, as above stated, the scratching or marring of the surface finish of the latter.
