Application September 14, 1950, Serial No. 184,805
6 Claims.
1 This invention relates to ventilators in general and particularly to the type adapted for association with sashes both of the double-hung and casement window construction.
The purpose of sash ventilators is not only to provide air circulation while windows are closed, but primarily are intended to prevent objectionable sweating and weeping, which manifestations are particularly common with. casement windows and windows providing light for chambers of small dimensions or other confined spaces, such as railroad cars, buses, automobiles and other vehicles.
The principal objects of the present invention are the provision of an extremely simple, inexpensive but nevertheless highly effective sash ventilator which consists of essentially only two prime components, and which components can be manufactured in continuous lengths with the intent of cutting them to required sizes corresponding to the width of sashes in which they are to be installed, and to which end it is proposed that at least one of the components constitutes a relatively simple, pre-fabricated extrusion shape of a uniform cross section, while the other component can be of suitable standard strip material, whereby the overall cost is brought to a minimum for most economic quantity production and equally economic and rapid installation.
'Another object of this invention is the provision of a ventilator structure which not only assures adequate ventilation to prevent window sweating, but which will effectively and positively minimize infiltration of rain and snow, exclude insects and eliminate draft, and which structure is adjustable to control the amount of air desired for passage through the structure.
A more specific object of the present invention is the provision of ventilators of the class indicated which are adapted to be readily fitted into the frames of existing as well as new window sashes by the simple expedience of replacing the bottom ends of window panes, in that the panes are suitably shortened and their bottom edges are set into channels forming the top edges of the fixed members of the ventilators, and of puttying or otherwise sealing the ventilators in the window frames as though they were parts of the window panes.
Another specific object of this invention is the provision of a ventilator composed of essentially two members, a stationary or fixed member adapted to be permanently associated with a sash frame and a movable member operative in respect to the fixed member, and wherein the fixed mem-.
2. ber comprises a triple channel-shaped structure with an upwardly open, pane-receiving channel formation at the top edge of said member and two oppositely disposed and bodily spaced channel formations, one adjacent to the pane-receiving channel, the other forming the bottom edge of the member, the web betweenthe two opposite channels being provided with spaced ventilating apertures, and a downwardly directed drip shield or cap extending outwardly along the entire length of the member above these apertures for excluding rain and snow; said movable member comprising a strip of suitable material inserted into and guided by the opposite channel formations of the fixed member and having louvered ventilating openings corresponding in number and position to the ventilating apertures in said fixed member, and means provided with the movable member for facilitating its adjustment and thus the positioning of its openings in respect to the apertures of the fixed member.
The foregoing and still other objects and additional advantages of the instant invention will become more readily understood from the ensuing description in conjunction with the accompanying drawings, disclosing a few of the many possible embodiments thereof, and in which:
Fig; l is a fragmental perspective view of a casement window provided with one type of ventilators in accordance with the present invention;
Fig. 2 is an enlarged perspective sectional view taken substantially along line 2--2 of Fig. 1;
Fig. 3 is a fragmental front elevation of a casement window equipped with a modified ventilator structure;
Fig. 4 represents an enlarged sectional view taken along line 4 of Fig. 3;
Fig 5 is a perspective modified embodiment of two corresponding ventilator members wherein the stationary member is provided with screenmg; and
Fig. 6 is a perspective view of still another embodiment of a movable ventilator member.
In describing the illustrations in detail, numerals l0 and II denote sash frames. The lower lights or panes 12 are shortened to accommodate a ventilating structure in accordance with the present invention. In Figs. 1 and 2 one form of such structure is illustrated. It consists of two continuous members [3 and M. Member l4 const tutes preferably an extrusion shape having a triple channel formation, there being provided a top channel [5 opening upwardly and adapted for the reception of the lower edge of a window "integral parts of these members.
pane I2 and directly below and adjacent to channel I an upper channel I6, and at the lower edge of member i3 a bottom channel II. The open ends of channels [6 and H are disposed directly opposite each other, the channels being separated or spaced by a relatively broad web l8 which is provided with a plurality of equally distanced apertures l9. Extending outwardly from upper channel 15 is a shield or drip cap 20 which extends along the entirelength of member :3 and overhangs apertures I 9.
As stated, member [3 is a continuous extrusion shape which can be readily cut to size or length to fit any existing or any new sash in which the ventilator is to be installed. In addition member 53 is adapted to be sealed, cemented or puttied in the sash frame, the same as would be the fullsize lower pane I2.
Member Id is made from a continuous strip of material which is approximately as wide as web It separating channels-l6 and H, and is adapted to beplaced within these channels and to be guided by them. From member M arepreferably stamped out openings 2i in such a way that upwardly-opening, inwardly projecting, pocketlike' louver structures 22 are formed, the bottom and sides of which being closed. The number and position of louvered openings 2% correspond wth'that of apertures 19 in member '13. In order tohfacilitate operation of member 14 in respect to member 13, there are provided grips or handles :23 which either form integral parts of member l4 or angular stampings which are fixedly secured to that member.
In the embodiment shown in Figs. 1 and 2 apertures E 9 and louvered openings 2 i 'in'the fixed and movable member, respectively; are shown in their simplest forms. In Figs. 3 and 4 a modified structure is illustrated whereinthe louver structure is somewhat broader and the movable members 14 are equipped with series of superimposed louvered openings '24 and handles 23 forming Fixed members 13 .are very-similar in every respect to members 13 of Figs. 1 and 2, with the exception that their apertures l 9" are somewhat longer to correspond with the area ofthe series of louvered openings 24 of themovable members.
Obviously apertures 19 and IQ of fixed members -l3 and [3 could be equipped with a-screening to prevent access to insects-dust or other matter, and such provision of screening is shown in. the embodiment illustrated in Fig. 5, and whereinfixed member l 13 again comprises a-top channel l l5 and-two oppositely disposed channels H6 and :I I1, top channel 1 i5 againformingthe upper edge of the fixed member, while-bottom channel 11'! serves as the loweredge thereof. There is again provided a drip cap l2i! extending over the .entire length of member: I [3. The
apertures .I I9 inthis embodiment are of ovalconstructionnand are provided with screening 25. The movable member i it again comprises a strip of material from which arestamped louvered openings .122, and adou-ble setUof/handles J23 facilitate the operation of the movable. member in respect .to the fixed member.
A modified form of the movable member .for use with fixed member l is is illustrated .inFigVG. and
is indicated-at i M, equipped with-louvered openings I22 and handle i23 the latterrformingan' integral part of the member.
In every one of the embodiments-shown::and
. described, the governing thought-is simplicity in structure, positiveness in operation and:reduction in cost. To that end the.fixediasa wellafasithe or'new window-sash frames, irrespective of their structure and purpose, the only other requirement being of shortening the lower end or" the glass pane and sealing that pane and the ventilating structure in the window frame as one unit. The advantage .of providing an upper, glass-receiving channel at the top edge of the stationary or fixed ventilating memberis of great advantage in the mounting and sealing of the pane and the Ventilator and reduces the cost of installation to a minimum.
- Whileinthe foregoing only a'few ofrthe many possible embodiments of the present invention are'described, it becomes-obvious that changes and improvements may have to be incorporated to meet various requirements, suchchanges and improvements being deemed to reside within the scope of the present invention as defined in the annexed claims.
