4 Claims. (Cl. 189-66) This invention relates to window ventilator and screen constructions particularly of extruded metal frame and sash types wherein the frame is especially well adapted for mounting in walls of block construction, preferably during erection, and wherein small units of such window ventilator and screen constructions with movable sashes provide screened ventilators in walls built of glass blocks, for example.

A primary object of the present invention is to provide an improved window construction of such units particularly with respect to the opening of the sash from a closed locked position, in a window frame in which a weathertight seal is maintained, to an elevated and inwardly tilted position permitting Ventilating air to pass both under thc lower edge of the sash frame and over the upper edge thereof, following the upwardly sloping wall provided by the` sash.

Another object of the invention is to provide improved mounting means for the sash which yieldably holds the sash in any desired sloping position to control the ventilating air passage and to provide a limiting gripping stop for the sash when it is opened to the fullest extent.

An additional obiect of the invention is to provide such mounting means including detachable pivot members for swingably mounting the sash frame upon the v/indow frame,` yieldable spring mounting members for slidably attaching the sash frame tothe Window frame, locking or latching elements and the like so that the sash will be retained in an effective manner by window frame in both closed and any open positions of the sash.

A further object of the invention is to provide such a construction wherein the frame is formed preferably of extruded parts to provide for both the mounting of the movable and swinging sash therein and of a screen adjacent the outer side of the frame with a water shed above the screen support, and means for locking the screen to the frame in a lower portion of the frame.

In addition, an object of the invention is to provide an improved frame sill and associated sash frame construction whereby the entrance of water, moisture, cold air and dust is minimized.

` Furthermore, an object is to provide means whereby the sash frame may be readily inserted into the window frame without any disassembling of the latter.

Yet another object is to provide a resilient connection of the side members of the sash frame and side jambs of the window frame, whereby the sash frame will not be apt to stick due to expansion of the members and jambs.

A further object is to provide an effective weatherstripping means carried by the sash frame side and head members.

Additionally, an object is to provide a window construction in which most of the framing parts are of extruded metal, particularly light-weight metal which re quires no protective coating.

Moreover, an important object is to provide framing parts of extruded metal, connected by the employment of novel connecting means with a view to reducing the Patent "ice expense of construction yet providing a strong assembly which is also especially precise as to dimensions and the angularity of the framing parts, one with respect to another.

Further` objects and features of our improved construction will appear in the following detailed description of a highly satisfactory construction of our invention as illustrated in the accompanying drawings forming a part of this specification.

In the drawings:

Fig. 8 is an enlarged fragmentary view partly in eleva tion and partly in vertical section, of the lower portion of the sash, as viewed from inside.

Fig. 9 is a similar fragmentary View of the same as viewed from the outside and with a portion of weatherstripping partly removed.

Fig. l() is a fragmentary elevation of the outer face of the sash.

In the drawings, wherein, for the purpose of illustration, is illustrated a preferred embodiment` of the invention and wherein similar reference characters designate corresponding parts throughout the several views, the letter A designates the window construction and B designates a wall into which the Window construction is set.

The window construction A includesa window frame 10, sash frame` l1 with glass 12 and screen 13 all constructed of a size particularly desirable for ventilation in a wall B composed of glass blocks 9S; the window in this instance being polygonal, three blocks wide and of the same height. While the construction is particularly adapted for ventilators in such glass block walls the invention is equally adaptable for other sizes and installation in other wall structures.

The window frame iti comprises extruded metal sill 14, lintel l5, and side jambe i6 comprising three forms of extruded metal strips.. Each of these strips has a main transverse wall i7 for the sill 14, 18 for the lintel 15 and 19 for the side jambs 16, the widths of which are in ac cordance with the thickness of the wall B. Each strip also has an inner tlange 2i? extending from the respective Walls 17, 18 and 19 and the anges may be provided with grooves 2 or the like formed therein in the extrusion process as an ornamental trim for the window frame inner casing. The sill 14 and side jambs i6 are formed in the extrusion process each with an outer flange 22. The flanges 2li and 22 on the sill and jambs, with their respective transverse walls, provide'outwardly extending channels which face adjacent portions of the wall B into which the window construction A is set during fabrication of the f wall B; of course itis obvious that if either of 'thes'etsetjs of flanges were separate and provided With any conveni Y tional form of securing means to secure them to the sill, lintel and side jambs the window construction could be applied in a nished wall and secured in place with a surrounding liner 96, usual mortar cementing material 97 and caulking 98 which seals the joints between the frame il@ and wall B. Y

Instead of an outer flange 22, the transverse wall 18 of lintel 15 is formed with an outwardly sloping water shed 24 terminating in a downwardly extending lip flange 25. This wall 18 also has a downwardly extending flange 26 spaced inwardly of the ilange 25, and from the outer surface of which a preferably small outwardly extending horizonal flange 27 extends with an upwardly extending ange 28 terminatingin a rounded portion 29. These latter two parts provide a pivot support means under the water shed 24 for the frame of the screen 13.

Transverse wall 17 of sill 14 has an upwardly extending ange 30 disposed inwardly of the flange 20 and spaced inwardly of the flange 3th is an upwardly extending flange 31 substantially paralleling the former and the space between the two flanges 30 and 31 provides room for opening of the window as will be explained hereinafter and also for the reception of any precipitation from the sash so that it will ilow to the exterior of the window frame instead of inwardly. The upper portion of the flange 31 is stepped, providing shoulders for abutment by portions of the sash frame to be described. At the base of the flange 31 may be provided spaced apart weep holes 32 for the exit of precipitation. It will be seen that sill 14 includes the wall 17, downwardly extending flanges 20 and 22, and upwardly extending flanges 30 and 31, all extruded as an integral strip.

The lintel 15 and side jarnbs 16 each includes an inwardly projecting flange 33, which is engaged by the outer surface of the frame 11 of the sash when the sash is closed, and a narrow, inwardly projecting flange 34, paralleling flange 33, which engages a portion of the frame of the sash 11 and provides a weathertight seal therewith when the sash frame is closed. Thus the lintel 15 includes the transverse wall 18, an inner flange 20, outside water shed 24 and screen supporting ilange 26 with its pivot means 27, 28 and 29, and two sash frame engaging flanges 33 and 34. The side jambs 16 each consist of a transverse wall 19, inside and outside trim and channel forming flanges 20 and 22 and sash engaging flanges 33 and 34.

In fabricating the sill 14, lintel 15, and side jambs 16 into a window frame 10, the extruded strips are cut to the required lengths, transverse walls 17 and 18 are preferably reduced in length by having their end portions cut away so that their reduced ends 35, as shown in Fig. 3, extend only slightly between the flanges 20 and 22 of the side jambs 16 and the ilange 30 of the sill 14 is cut away at its ends so as to engage the inner surface of the transverse walls 19 of the side jambs, while the side jambs 16 have their transverse walls formed with end projections 36 as shown in Figs. 2, 3 and 5, which extend through appropriate slots in the transverse walls 17 and 18 of the sill and lintel respectively and the extremities of the projections 36 are pressed or peened over so as to integrally connect the sill, lintel and jambs.

The lower ends of the sash frame engaging flanges 33 and 34 are cut square so as to provide abutting engagements with the sill transverse wall 17. Likewise the inner and outer flanges 20 and 22 engage the upper surfaces of the corresponding ilanges of the sill 14. Thus, with the square cut of the ends of flange 30 on sill 14, all parts are cut for right-angular relationship, one with respect to another.

The same right angular relationship of the side jarnbs 16 and lintel 15 is maintained in a similar manner. Sash frame engaging flanges 33 and 34, as best shown in Fig. 6 are cut at substantially 45 angles so as to have mitered engagement. Trim flange 20 of each jamb frame is preferably square cut to engage the under surface of the same flange `of the lintel 15. Outer trim flange 22 of each jamb is square cut below the upper end of transverse wall 19 thereof so as to fit against the lower edge of ilange 26 of the lintel.

Thus a most accurately dimensioned and truly squared frame of extremely strong construction is produced at a minimum expense and yet attractive in appearance and l: when the preferred aluminum or its alloys is employed,

a very light weight structure is provided.

For mounting the frame of the sash 11 in the window frame 10, as shown in Fig. 3 the transverse walls 19 are provided with apertures 37 midway between flanges 33 and 34 and below the upper ends thereof. In these apertures are mounted studs 38 each having a concentric bore 39 for receiving a pivot pin 4i) as best appreciated in Figs. 4 and 5. The pins 40 are provided with enlarged heads 41, with a kerf 42 in the outer face of each head,.and the shank is provided with a transverse aperture or bore 43 in the same axial plane as the kerf so that the position of the aperture is easily determined when the pivot pin is positioned in stud 38 for aligning the aperture 43 with a like aperture 44 in stud 38 for receiving a cotter pin 45v to lock the pivot pin in place. Stud 3S is in shouldered en-V gagement with transverse wall 19 with a reduced end por-V tion, as shown in Fig. 3, extending through aperture 37 in' the transverse wall 19 and pressed or peened over into a locking engagement with the outer surface of -this wall.

As best shown in Fig. 4, the horizontal transverse wall' 18 of the lintel has depression 47 formed therein preferably by a punching operation to upset a portion of the metal for receiving a conventional sash latching member or catch 48 carried by the sash frame 11; a keeper 49 mayv also be provided secured to the underside of the wall 18 t-o provide additional engaging surface for the bolt 50 of the catch 48. .t

The vertical transverse Walls 19 of the side jambs are preferably provided with slots 51 adjacent their outer` edges for receiving screen latch elements 52 as best shown in Fig. 7.

The window frame 10 of the window construction A is thus complete for installation and reception of the sashV frame 11 and screen frame 13 which are detachable units of such construction that they may readily be applied; after the sash frame is installed in a wall structure, and just as easily removed therefrom as desired when unlatched.

Sash frame 11 is also preferably fabricated from extruded metal strips preferably aluminum or aluminum alloy and comprises, an upper rail or head member 53, side stiles or members 54 and lower rail or bottom member 55, with these four members being miter fitted and preferably welded at their corners to provide substantially` true angles and a very sturdy construction. The rail 53 and Stiles 54 are substantially identical conformations of extruded metal and each rail and stile 53 and 54 has la transverse wall 57 and spaced apart inwardly extending flanges 56 and 58 normal thereto. The inner flanges 58 terminate in small transverse ilanges 61 the free ends of which engage the inner surface of the sash frame transparency or glass 12 and each llange 58 has an intermediate larger transverse llange 63 which substantially parallels the flange 61 and extends over the edges of the glass. The flanges 56 and 58 extend to the inner faces of the walls 57. However, the bottom rail 55 differs from the rails and stiles 53 and 54 although it has a transverse wall 59 corresponding to the walls 57 and a transversely shortened llange 6i) which takes the place -of the flanges` 58 since the free lower edge `of the flange 60 abuts the place of the flange 56, which is provided but it has a shouldered free end to engage the shouldered free end of the flange 31 and provide a desirable connection ofsash and window frames, whereby there is` little if any penetration of moisture to the space between the flanges 30 and 31. As may be seen in Fig. 4, in order to mount the sash frame 11 in the wind-ow frame 10 each side stile 54 is provided with pivot lug 66 having an enlarged outer head 67 and the shank 68 is` extended through a suitable aper ture in the transverse flange 56 with its projecting portion peened to secure it in place. A link bar 69 pivots on each of these pivot lugs and has a recess therein into which the head 67 of the lug is received. When the sash frame 11 is mounted in place in the window frame 10, the upper ends of bars 69 which are correspondingly apertured and recessed for receiving pivot pin 40, receive this pivot pin 40 positioned therethrough and extended into aperture 44 in the stud 38 mounted on the transverse wall 19 of the side member 16, and the c-otter pin 45 is inserted to detachably secure the window and sash frames together.

The pivotal axis for the swinging of the sash frame 11 is slightly above the horizontal plane of the bottom of the sash as defined by the lower edge of the flange 65 being determined by guide means 70 at each side of the sash frame 11. Each of the means 70 includes a slide member 71 having a web portion 72 from the longitudinal edges of which extend parallel flanges 73 and 74, the first extending substantially the full length of the web portion 72 and the latter falling short of the bottom edge of the web portion. The members 71 are adapted to slide freely along the channels defined by the flanges 33 and 34 and adjacent portions of the side jambs 16 but they are adapted to cant and provide frictional gripping connections between the Window frame and sash frame, whereby they will maintain the sash frame at any desired tilted position (within limits) with respect to the window frame as will be described. These members 71 are apertured to receive the headed pivot pins 75 and their enlarged heads 76 are disposed within the channels of the members 71. The Shanks of the pins are shouldered with reduced ends 77 extending through apertures in the lower end portions of mounting strips 78, the reduced ends being peened to rigidly secure the pins in place. An expansion spring 79 is positioned between the faces of the members 71 and the mounting strips 78. These springs 79 yieldably retain the members 71 in their outermost positions on the pivot pins 7S so that their outer surfaces will frictionally engage the jamb transverse walls 19 between flanges 33 and 34 thereof and also apply friction to the canted members 71 in their engagement with the flanges thus tending to maintain the sash in any desired adjusted open pos1t1on.

Mounting strips 78 are also extruded aluminum or alloy elements and, while quite rigid, have elasticity so as to cooperate with the springs 79 in aiding the members 71 1n accomplishing their purposes. These strips extend upwardly along the vertical transverse flanges of side stiles 54 of the sash frame with their lower portions held in an outwardly flexed position by pairs of rivets 80 extending therethrough and through the transverse walls 57 with tleir inner ends 81 peened over to secure the strips 78 in p ace.

In order to insert the sash frame 11 into the window frame lll, the pivoting link bars 69 being free at their upper ends, the sash frame 11 is held yat an angle as shown in Fig. 6, then rst one member 71 is inserted between flanges 33 and 34 of side jamb 16 and then the other member 71 between the corresponding flanges of the other side jamb. The sash frame is then manually held in an inwardly tilted position as shown in Fig. 4 and the link bars 69 are connected by pivot studs 40 as previously described and as indicated in Fig. 5.

It will be noted that the pivotal connections of link bars 69 are quite free, the bars acting as supports for the sash, raising the lower end of the same as it is swung inwardly as shown in Fig. 4 in which view the sash is swung to substantially its extreme limit.

The screen frame 12 likewise is preferably formed of extruded aluminum or allow strips. The strips are cut into four piecesk with mitered ends so as to form a rectangular `frame 82 with a screen edge receiving channel 83 and a locking strip 84 which fasten screen material 8S to the frame. The framehas an upwardly and slightly outwardly extending flange 86 on its upper part which flange ter1ninates in a Semi-cylindrical formation 87 for engaging over the rounded portion 29 at the upper end of the screen supporting flange 28 carried by the window frame lintel 15. Thus the screen frame is mounted so as to swing outwardly from its upper edge and, when drawn into engagement with the outer trim flanges 22 of the window frame, its upper edge is held in tight engagement with the Window frame elements by the` flange and cylindrical formation 87 in cooperation with the rounded head portion of flange 28.

As shown in Fig. 7 the screen frame 82 is secured in its closed position by means of the latch element 52 engaging slots 51 in the transverse walls 19 of the side jambs 16. This latch element 52 is part of a lever S9 pivoted at 90 to the screen frame and provided with an outwardly extending, fingerpiece 91 by means of which the latch elements 52 may be swung into and out of engagement with slots 51 of the window jamb.

The edge portions of the walls 57 of the sash frame which face toward the flanges 33 of the lintel and side jambs of the window frame together with the narrow flanges 58 are provided with longitudinally-extending grooves or recesses 92, accommodating strips of weatherstripping 93. This Weatherstripping is vinyl plastic material and projects slightly from the faces of the stiles 54 to engage the flanges 33 when the sash frame is in a closed position.

Various changes may be made to the form of the invention herein shown and described without departing from the spirit of the invention or scope of the claims.
