Hargrett, Wyandotte, Mich. Application December 8, 1944, Serial No. 567,200 2 Claims. (Cl. 98-99) 2 This invention relates to improvements in ven tilators. It is an object of the invention to pro~ vide. a ventilator including ka downwardly and out wardly inclined deiiector plate spaced above the bottom of a window frame opening and secured therein so that a sash may rest upon the said . plate 9 made either in one piece as shown in Figures l and 2, or in two pieces as shown in Figures 3, 5 and 6, and two supports l0 on which the opposite extremities of the defiector plate are secured. When the deilector plate is made in two pieces they are both of substantially the same deñector plate to allow fresh air to flow inwardly cross section and are relatively slidable one upon between the underside of the latter and the bot~ the other transversely of the windowirame l to tom of the> frame opening and at the same time adjust the length of the ventilator to suit win to prevent rain from' entering. dows of different Widths. Formed along the in Another object of the invention is to provide ner margin of the deîiector plate. 9, or along such @ventilator wherein a, ledge is provided along 4both pieces or sections thereof, is an upturned the inner side of the deflector plate to support flange l! which is adapted to lie adjacent the the lower rail of the window sash and wherein inner face of the underside of the lower sash 6, means are provided for preventing raising of the 15 and formed in the ilange Il are vertical open sash from the outside. ended slots l2 extending from its upper margin A further object of the invention is to provide to receive suitable securing means, such as thumb such a ventilator with a movable closure plate for screws l2a, which are threaded intothe lower closing the opening between the deflector plate rail of the bottom sash 6 from the inside to engage and the bottom of the frame opening so» that in 20 ‘the flange Il and prevent the sash being raised extremely cold or windy weather the ilow of air from without. Forming part of the deflector beneath the deflec‘tor plate may be stopped. plate, or of each piece thereof when it is made Yet another object of the invention is to pro in two pieces, and projecting outwardly from the vide such a ventilator in one modiñcation of which base of the flange Il is a ledge I3 upon which both the deñector plate and the closure plate are 25 the lower sash 6 rests, and projecting outwardly adjustable for length so that the ventilator may from the ledge, o1' ledges, I3 the deflector plate, be employed for windows of diiîerent widths. or each piece thereof, is downwardly and out Having thus briefly and broadly stated sonne wardly inclined and terminates along its outer margin in a downwardly and inwardly rolled edge Will now describe it with the aid» of the accom 30 i4. It will be noted that the total outward pro panying drawing, in which: jection of the de?lector plate is such that its rolled Figure l illustrates a cross section of the» lower edge i4 is positioned inwardly of the outer faces portion of a window frame in which the inven of the vertical strips l5 which form the outer of the objects and advantages of the invention I tion is mounted, and is shown as a section on the line I_I of Figure 2. Figure 2 is a section on the line 2_2 of Fig sides of the stile grooves 3 against which a screen l@ is normally secured. Thus my ventilator in ure 1`. no wise interferes with the installation of a screen in the normal manner. Figure 3 is an enlarged section on the line 3_3 of Figure 2, but showing a slight modification in that the deflector plate is made in two sections. Figure 4 is a section on the line 4_4 of Fig one or more elongated slots l1 are formed through ure 3. Figure 5 is a disassembled perspective view When the deñector plate is made in two pieces each piece, and a slot in each piece is arranged at least in partial registry with a slot in the other piece so that a bolt i8 may be inserted through both pieces of the plate to hold their overlapping ends together with the aid of a screw I9'. Ob showing the modified form of the deñector plate and the closure plate, one support and one pad. 45 viously by moving the two pieces of the deiiector Figure 6 is a section on the line 6_6 of Fig plate 9 relative to one another the total length ure 3. of the plate may be adjusted to suit the width Referring to the drawing, I designates a con of the window in which it is to be employed. verrtional window frame having a usual opening Formed on the outer extremities of the de 2 therein provided on opposite sides with ordinary ' llector plate 9, or on the outer extremity of each stile grooves 3 and 4 to receive opposite vertical piece thereof, are tongues 20 which extend into margins of an upper sash (not shown) and a the stile grooves 3 and 4 on opposite sides of the lower sash 6 respectively, and parting strips 'l frame opening 2. Each support iii consists of dividing the grooves 3 and 4. a vertical portion 2l of angle-section having a 'I'he ventilator consists primarily of a deiiector 55 relatively small foot 22 at its lower extremity 2,403,596 4 which projects toward the foot on the opposite vertical portion 2|, and extending from its upper extremity are tongues 23 which extend into the stile grooves 3 and 4 beneath the tongues 2i! to support the latter. Inserted between the tongues 20 and 23, which are riveted or otherwise suitably secured to one another as shown at 25, are felt pads 21 the edges of which project inwardly be tween the tongues as the size of the stile grooves means consists of curved resilient contact edges 34 formed for a short distance along the outer margin of the closure plate 32 from its outer ex tremities which are positioned to resiliently en gage the rolled edge I4 of the deflector plate 9 so that the closure plate is suñiciently held there to to prevent it accidentally dropping to its low ered position. While in the foregoing the preferred embodi- ' 3 and 4 in different windows is apt to vary, and ments of the invention have been described and by making the pads larger than the tongues they shown, it is understood that further alterations and modifications may be made thereto provided will occupy the full Width and depth of larger grooves and thus assist in firmly holding the ventilator in position. One flange 2id of each angle-shaped vertical portion 2| bears against the outer face of one parting strip ’l and across the outer and inner stile grooves 3 and_4, and the other flange of each of the vertical portions bears against the inner vertical side of one of the inner stile grooves 4, Extending through each 20 the said alterations and modifications fall within the scope of the appended claims. What I claim is: 1.'A ventilator comprising supports including angle-shaped vertical portions, feet projecting from the lower extremities of said portions for attachment to opposite sides of the base of an opening formed in a window frame, one flange flange 2Ia is a screw 24 in threaded engagement of each angle-shaped portion lying contiguous to with are secured one of in theposition partingon strips the base 1, andofthe thefeet frame the inner face of a stile groove formed inthe frame and the other flanges resting against strips defining the stile grooves, tongues on -"said sup opening 2 as yby screws 25. I In addition I also provide a closure plateSZ for opening and closing the space between the de ilector plate 9 and the bottom of _the frame open ing 2, since, unless the ventilator is completely removed, it is impossible to pull the sash E down onto cold very the bottom days it of may thebeframe `desirable opening, to close andthis aperture. The closure plate 32, like the dei’leetor plate 9, may either be made of a single piece> of material as shown in Figure 2, or of two relatively adjustable pieces as shown in Figure 5 and having -their extremities secured to one another as by a ports extending into the stile grooves, a deiiector plate in the frame opening spaced above the bot, torn thereof, said plate having other tongueson its extremities supported on the first named tongues, flexible pads wider than said tongues ar ranged between the upper and lower tongues, said plate having a ledge formed along it to support a sash movable in the stilev grooves, an upward flange extending from theinnel'r margin of the ledge’to yrest contiguous to the inner face of the sash, and the deflector plate extending downwardly and outwardly from the .ledge to bolt 38 and nut 39Y extending through both the form an air passage between it and the underside said pieces.
