Definitions
- FIG. 5 is a diagrammatic representation of FIG. 5.
- the present invention relates to ventilators for use with windows and is particularly well adapted for use with double hung window frames.
- ventilator in common use is that which is telescopic or adjustable lengthwise, to suit various widths of windows, between the pulley stiles, to fit beneath the lower sash of a double hung window, and rest upon the window sill. While such type may be readily removed and is not apt to damage woodwork of the decorative finish, it may be readily removed by unauthorized persons from the outside 'of the building, and usually is not symmetrical in appearance so that it detracts from the architectural effect.
- the principal object of the present invention is to provide a ventilator for window frames which may be easily and quickly placed, without likelihood f damaging the window construction or the finish thereof, since it fits between the pulley stiles and between the sash and sill; and which cannot be collapsed or diminished in over all length, so that if the sash is locked, either to the casing or to the upper sash after the ventilator has been placed, the latter cannot be readily removed without breakages unless the locked sash is first released.
- the invention contemplates the provision of a rigid rectangular frame, supporting a transparent or translucent deflecting shield which ma be held in a closed position with respect to the frame, to prevent the ingress or egress of air, or adjusted to various open positions, this frame being of a length almost as wide as the window opening so as to permit of entry of considerable light into the building; and rigid filler pieces which may be slid into place, from above to occupy substantially the entire space between the rigid ventilator frame and the pulley stiles and to fit snugly between beads of the window casing.
- a ventilator having symmetrical appearance and relatively small opaque areas at the ends of the frame, is provided, which cannot be readily removed without withdrawing the filler pieces verticall 'from between the main frame and window casing.
- the sash may have a width of two feet and two inches, the next size, two feet and four inches, the next,'two feet and six inches, and so on.
- the sash may have a thickness of one and three eighths inches and for better.
- Another object of the invention is to provide window ventilators of the insertable type which when installed are comparatively weathertight when'the deflecting shields are closed, so they may be used in cold localities and those subjected to driving rain or snow storms without danger of ingress of moisture or air when ventilation at the window is not desired.
- a further object of the invention is to provide ventilators which will fit neatly with respect to the many designs of lower sash rails, and the sills and stools of window frames, so that the assembly will have good appearance and conceal any rough or uneven edges of the rail and stool.
- Fig. 5 is a view similar to Fig. 4, but showing "the filler piece in place,-. thenlower sash resting upon the ventilator;.and the upper and lower sashes locked togetherrso that the ventilator cannot be removed fromtheoutside of the window.

Application February 14, 1947, Serial No. 728,578
3 Claims. (01. 98-99.7)
The present invention relates to ventilators for use with windows and is particularly well adapted for use with double hung window frames.
Various devices have been provided for use at windows, to permit ingress and egress of air to and from rooms. Some of these are affixed to the architraves or stop beads of the windows. These types of ventilators require considerable skill, if they are to have neat appearance when installed. It is often desirable to remove the ventilators during fair seasons, such as for the late spring, summer and early fall, and these types of ventilators, when removed, leave the frames marred, such as exposed holes made by screws, nails or other fastening devices, and parts may stick to the paint or other finish leaving such unsightly when the ventilator parts are pried therefrom. It is frequently found, upon removal of such types of ventilators that the decorative coatings of the window frames, which were .con-
cealed by parts of the ventilator, are of a different color than the remainder of the coatings, due to fading, so that the entire frames must be redecorated, or the unsightly contrast of colors left to view.
Another type of ventilator in common use is that which is telescopic or adjustable lengthwise, to suit various widths of windows, between the pulley stiles, to fit beneath the lower sash of a double hung window, and rest upon the window sill. While such type may be readily removed and is not apt to damage woodwork of the decorative finish, it may be readily removed by unauthorized persons from the outside 'of the building, and usually is not symmetrical in appearance so that it detracts from the architectural effect. Also, in recent years, it has been found desirable to provide ventilators using glass or other transparencies as deflecting shields for incoming air currents, so as to not shut off considerable light from the outside, and these telescopic types of ventilators have considerable opaque areas exposed to view at the adjustable zones.
The principal object of the present invention is to provide a ventilator for window frames which may be easily and quickly placed, without likelihood f damaging the window construction or the finish thereof, since it fits between the pulley stiles and between the sash and sill; and which cannot be collapsed or diminished in over all length, so that if the sash is locked, either to the casing or to the upper sash after the ventilator has been placed, the latter cannot be readily removed without breakages unless the locked sash is first released.
, grade, one and three quarters inches.
The invention contemplates the provision of a rigid rectangular frame, supporting a transparent or translucent deflecting shield which ma be held in a closed position with respect to the frame, to prevent the ingress or egress of air, or adjusted to various open positions, this frame being of a length almost as wide as the window opening so as to permit of entry of considerable light into the building; and rigid filler pieces which may be slid into place, from above to occupy substantially the entire space between the rigid ventilator frame and the pulley stiles and to fit snugly between beads of the window casing. Thus a ventilator having symmetrical appearance and relatively small opaque areas at the ends of the frame, is provided, which cannot be readily removed without withdrawing the filler pieces verticall 'from between the main frame and window casing.
It is common practice to somewhat standardize double hung window frames, so that the dimensions of the window openings, in width, vary as to different sizes, by one inch or two inches or other unit of measurement. By way of example for some windows the sash may have a width of two feet and two inches, the next size, two feet and four inches, the next,'two feet and six inches, and so on. For comparatively inexpensive window construction the sash may have a thickness of one and three eighths inches and for better The present invention makes possible the stocking Of a comparatively few sizes of ventilator frames and a variety of sizes and shapes of filler pieces to meet the average demands of persons in a locality seeking ventilators without resorting to unsightly, unsymmetrical assemblies or patchwork when installing.
Another object of the invention is to provide window ventilators of the insertable type which when installed are comparatively weathertight when'the deflecting shields are closed, so they may be used in cold localities and those subjected to driving rain or snow storms without danger of ingress of moisture or air when ventilation at the window is not desired.
A further object of the invention is to provide ventilators which will fit neatly with respect to the many designs of lower sash rails, and the sills and stools of window frames, so that the assembly will have good appearance and conceal any rough or uneven edges of the rail and stool.
Other objects and advantages of the invention will appear .in the following detailed description of the preferred embodiment of my invenof sill portion 23. common practice in building construction, but it is pointed out ,that'it .isto the stop beads I1 or "the architraveii!

from the confronting ifaces M and 50f which project the parting beads Wand-stop beads I1, and lower and upper sashes Hi and I9 respectively. Theframe isshown as having an architrave 20, outside. casing .Zl and screen-'22 disposed upon the .sill and'engaging-the trim. The
sill II is shown as comprisingamain body portion 2-3, the-upper face .24 of:which slants downward toward the outside of the building, from .a stool'25,;having a top face 26 andan outer-side faceZ'l in angular relation to each other.
in Figs. 4 and 5. The bottom:rail 28 has its lower surface beveled downwardlyand outwardly, as
at 32, to conform to-the pitch of the upper face .All of these .details disclose tilators now in common use are attached as herefiinbefore disclosed; and that it "is the margin of the stool portion- 25-at the juncture of the faces ,26 and Z'L-and the margin-at the juncture between the bevelr32. and inner;face*33 of the bottom:
The lower sash includes a bottom rail 28 parting rail "29 and stilestll andthe'upper sash is also of ordinary construction, including a stile .31, shown 4 rail 28 that are frequently found to be uneven or rough, due to warping or wear and tear in some buildings. The thickness of the sash is usually standardized to the dimensions'of 1% and 1% inches and hence the pairs of beads 16 and H are spaced apart rather accurately, to slidably engage the upright margins of the sash according to the thickness thereof;
The ventilator preferably comprises mainly an elongated rectangular frame 36, filler or side'extension pieces 3?, to engage the pulley stile between the beadsll and i8, and a deflector shield .38, for direc'tingincoming air primarily to portions of the room where such is desired. In the i extruded metal sections suitably welded or otherexample shown; the deflector shield comprises a plate :39 and segmental side wings 49, resembling somewhat those elements shown alsoshown a suitablelatch H for retaining the -plate 39 in a position closing the opening of frame 36, when such is desired, ,a knob arrangement 42 on the platediand a window lock 43, which may be used to..lock ,thesashes {1,8 and 19 together .when the lower sash has been raised to a pr-edetermined height. This lock may be of any suitable character, such as is ,disclosed in Patent 1,580,611. grantedto .C. Kirkpatrick, April 13,
The frame .36 ispreferablymade of rolled or Wise secured together and preferably comprises a lower rail-A5,.annpp6r railAB and stiles .47.
,The, rail 45, asshownmore in detail in Figs. 3 and 6 is preferably shapedforsturdiness, to conceal any unevenness -or..r 0ugh-ness along the previously mentioned-margin of the stool 25, and to provide a supportfor the-plate 3.9 as wellas conduct any moisture contacting andflowing downwardly on the outsideof plate,39,to the pitched surface of $il1,po12tion"23,. Withthis in view the rail 4 5 preferablycomprises an. upwardly opening horizontal trough '50-,paralleling the juncture between the faces 26-and21 of stool 25,,an inside yvall 5| of the trough preferably abutting against the face 21,,a, first flange portion-52 engaging upon the face 2 5 'andconnected to the wall 5|,
this flange portion '52.bei f preferably and mainly of inverted 'V-shape crosssection '53. and terminating in a minor flange 154 forintimate contact with the top surface of stool 25; .and a second fiange portion55 joined to the other side of the trough '50 and includinga major section or web 56 having an up per;fa,ce15l inclining downwardl-y and outwardly from the trough 50, this is preferably joined to the upper portion of the trough 50 by an integral flange 51* and it is also preferred to provide a depending'flange 58 along the other margin of web 56 which may engage, with intimate contact, the sill body 23, as shown in Fig.6.
The upper rail is-also preferably shapedfor sturdiness, to-conceal any unevenness or roughness of the lower inner-margin of sash rail 28, and to provide an abutment for the uppermarginal portion of plate '39. This rail is shown more in detail in-Figs. 1 and 3 and preferably channel shapedin cross section, includinga web '59 and upstanding fianges'fi'll and BI, the web 59 having a depending angular fiangeBZ forming an inwardly opening channel 63 for receiving a packing strip'64 of sponge rubber or the like, which is engaged by parts of the deflector shield 38 as hereinafter described. The flange 60 preferably has its upper margin bent outwardly of the chan nel as shown at 95, the flange having intimate contact with the inner face of sash rail 33. The depth of web 59 is preferably made less than the thickness of the sash rail it is to engage so that the upper mar-gin of flange 6| will engage the underside of the sash rail. For instance if the sash of minimum thickness for which the ventilator frame is intended, has a thickness of 1% inches, the Web '59 will be made of a depth less than 1% inches, thus assuring a fit with not only a sash having this dimension but also with those having greater thickness, such as one of 1 inches in thickness.
Referring now to the stiles 4'! they are each preferably similar to the upper rail Mi in that each is of channel cross section, comprising a web 66 outer and inner flanges l9 and l l, respectively and an inwardly extending angular flange 12 forming a channel 13 for receiving a packing strip M to engage a portion of the deflector shield 38. The channels of the stiles 41 are each open at the top and endwise of the frame, and may also be open at the bottom thereof, for reception of the companion filler or extension piece 31. The free margin of flange 19 may be formed with a bead 15 to give good appearance and to provide a substantial abutment for resisting any attempt to pry the adjacent piece 3? from its position between the window beads l6 and I1.
The over-all length of frame 39 is at most, less than the distance between one of the stiles and the faces of the beads 16 and ll on the other stile whichconfronts same. In other words this length is less than the distance of stile 12 from the faces of beads I 9 and I! on stile I3 which confront stile l2, and preferably the length of the frame 36 is less than the distance between the confronting faces of the pairs of beads l6 and I? on stiles l2 and I3, so that the frame may be placed in the window opening by movement transversally of the plane of the window. This is essential where two filler or extension pieces 31 are used and the over-all thickness of the frame 39 is greater than the space between the beads l6 and H on their respective pulley stiles as shown in Fig. 2.
In Fig. 4 the frame 36 is shown in position in the window opening, with the lower sash I8 raised high, and a hand is illustrated in the act of placing one of the filler or extension pieces 31, by sliding it downwardly between the frame 36 and the pulley stile and between the parting and stop beads on such stile. The pieces 31 are preferably made interchangeable, so it suffices to describe merely one in detail. Each piece 3! is preferably made tube like, so as to provide a hollow 1B. This formation facilitates manufacture of the piece from rolled sheet metal stock or extruded metal, renders the piece comparatively light in weight, but sturdy, and permits placing of one or more lugs or finger holds IT in the hollow to facilitate placing and removal of the piece with respect to the ventilator frame and window. The piece 31 is coextensive with the stile 4'! of the ventilator frame with which it cooperates and comprises a first portion 18 substantially as thick as the stile 41, and a second reduced portion 19 fitting in and slidable longitudinally of the hollow of the channel shaped stile 41. The reduced portion 19 provides a shoulder 89 for engagement with the bead 15, as shown in Fig. 2 to limit the extent to which the reduced portion 19 may be forced into the hollow of stile 41. Since the distance between the pulley stiles l2 and 13 of windows specified as of a given size may vary slightly, due to shrinkage of wood by way of example, it is preferred to provide each piece 31 with a spring device 82 to compensate for such inaccuracies and to make the assembly as weathertight as 1308-- sible. The spring device may be in the form of a strip of spring metal, such as Weatherstrip material, having a major central portion 83 arched transversally and bordering minor flat flange portions 85, to engage the web 69 of stile 4'1. spring device 82 as well as the lugs 11 may be secured to the reduced portion 19 by rivets 39 and it is preferred to provide a lug 1! adjacent each end of the piece 31 so that, no matter whether the piece is placed at the left end or right end of the ventilator frame, there will be readily accessible one of these lugs which may be engaged by the finger of a person when exerting an upward pull on the piece 3'5 to remove it when disassembling the ventilator with respect to a window. The spring device 92 in reality forms a part of the filler or side extension piece 37 and functions only to prevent the adjacent parts of the ventilator from rattling, due to wind forces, etc., and to effectively close the space between the ends of the ventilator frame and the window stiles.
The deflector plate 39 may be made of glass, sheet plastic material or the like and is preferably transparent or translucent. It preferably rests on a shock absorbing strip 88 of rubber or the like resting on the bottom of the rail trough 50 and on which it pivots as shownby full and dot and dash lines in Fig. 3. The side wings 49 are segmental in shape and each comprises a main body portion 89, an outturned radial flange 99 to engage the stile 4'! for limiting swinging movement of the wing in one direction, and a radial channel portion 9! for embracing the end portion of the plate 39. The channel portion 9| engages the packing strip 14 and the top edge of plate 39 engages the packing strip 94 when the plate is swung to a position closing the ventilator frame opening. It will be noted that the vertex end of the side wing also rests on the strip 88 and the arcuate upper edge portion 92 of the wing is accommodated in a slit 93 in the angular flange 92, as shown in Fig. 2. This edge portion 92 may be provided with several pairs of spaced dimples 96 to yieldably hold the deflector shield 39 in various open positions by frictional contact of the dimples with the packing strip 69. The angle flanges 62 and 12 are preferably located well forward toward the flanges 69 and 19, respectively, so as to dispose the plate 39 well toward the inside of the window opening and to permit use of rather wide segmental side wings w'which may be accommodated in the window opening, without touching the screening of screen 22, when the ventilator late 39 is in a closed position, as shown in full lines in Fig. 3.
The knob arrangement may comprise an attaching channel 99 cemented or otherwise secured to the upper portion of plate 39, midway of its ends, and a knob 97 attached to a lip 98 integral with the channel 96. The latch ii may comprise a rotatable knob 99 attached to the flange 99, midway of its ends, the knob 99 carrying a finger 99 which may swing to engage the face of channel 96 when the shield is in a closed position.
It will be noted from Figs. 9 and 10 that filler pieces 3'1 may be made in various sizes so that a selection may be made among them for use'with the particular ventilator frame to be used and according to characteristics of the particular window'in which the ventilator is to be installed.
The
:sizes.
1 maximum size filler piece being shown in the lower portion of Fig. 9. If the sash is 1% inches thick then a selection fromthe types of filler pieces shown-inFig. 10 may be made, the upper piece in the view being the minimum size for the smaller window opening and the lower piece in the view being for the larger size window opening.
' It will be noted from Fig. 4 that the ventilator may be easily installed when the upper sash is raised high without danger of damagingthe window or meaning the finish thereof since the frame 36 may be held in place with one hand and the filler pieces 31 slid downwardly between the ends of the frame and the window pulley stiles, using the other hand to accomplish such. The pieces "31. then close the spaces between the ends of the frame'36 and the stiles l2 and I3, and also fill the spaces between the beads l6 and IT at the zone'of the ventilator, making it impossible to remove the ventilator without first withdrawing the filler pieces in "an upward direction. As shown in Fig. 5, the window lock 43 may be thrown to ,prevent such removal of the ventilator unless the sashes are'first released to permit raising of the lower sash sufiicient to gain access to and remove the filler pieces.
The assembled ventilator has very neat appearance as may be observed from Fig. 1 and the ventilator may bemade so as to admit as much if not more light into a room than if omitted and the lower sash moved to a closed position engag- .ing .the window sill. I
