3 Claims.

This invention relates to window construction and more particularly to an integrated window frame having a movable window sash in its lower portion and glass blocks in its upper portion.

In recent designs for buildings, glass blocks have frequently been substituted for the more` conventional window constructions. However, the usual practice of filling the -`entire Window opening with glass blocks has been found unsatisfactory in many applications and the need for a practical modication hasbeen recognized for some time. One major objection to solid panels of glass blocks in public buildings has been that they seal window openings which previously served as exits in the event of fire or panic. This objection has been a major consideration limiting the use of glass blocks in school and auditorium construction.

A further objection to said solid panels of glass blocks has been the inability lto open Said panels for needed ventilation. This situationfbecomes a serious obstacle both in single dwellings, where adequate air conditioning systems are not installed, and in multiple unit dwellings or large buildings where failure of the air conditioning system might necessitate evacuation of the building unless other means of ventilation were available.

Attempts have been made to solve the ventila tion problem, only, by providing a. glass sash,

hinged along its lower edge, in conjunction with said glass blocks. However, this arrangement has proved unsatisfactory, especially when used at any great distance from the ground or roof, because there is no convenient way to clean .the outside of either the window or the glass blocks.

Hence, it is desirable that a frame be designed to support a vertically sliding sash as well as glass blocks, thereby providing an opening of sufficient size to permit the passage therethrough of a mans body. It is further desirable that such frame be capable of supporting anchors for a Window cleaners safety belt in such positions that said Window cleaner can reach all of the glass blocks.

Although these problems have existed and have been recognize-d almost since the introduction of glass blocks as a standard construction material, not until my invention had a satisfactory solution thereto beendeveloped. The advantages available from the use of glass blocks are such that a suitable modication of the glass block window, overcoming these disadvantages, has long been desired.

My linvention provides substantially all of the advantages of glass blocks plus those of a conventional window equipped with a vertically slidf ing sash. Howeventhe construction of a window having both glassblocks and sliding sash construction involves several diiiicult problems. In order to provide an easily accessible exit for emergencies or kfor panel and window cleaning, it is advantageous that the opening to be covered by the sliding sash be located in the lower por# tion of the window. Thisrequires a structure of sufficient strength to support the glass blocks mounted above the opening, Therefore, one of the majorproblems overcome in designing .my window frame has been to provide an economical frame guiciently strong to' support the weight ot the blocks. In' addition, the frame must be pleasing in appearance and relatively simple to fabricate and 'installP The factor of strength is of utmost importance 20 because glass blocks'are heavy, especially if the Particularly is this a crucial requirement with` 25 glass blocks occupying the upper portion where their weight will tend to deiiect the central por-v tion of the frame. Although this applies particu.-

larlyV to that'p'ortion ofl the window acting both as a vsupport for the glass blocks and as a divider between the upper and lower portions of the window, it is also necessary for the entire frame to be so Aconstructed that it will retain its true shape despite the forces to which it is subjected.

Another type of problem retarding the use of glass blocks is the difculty of laying them.` The proper laying of glass blocks requires skill and knowledge different from that of the average mason because of their greater co-efcient of expansion and tendency to loosen from the bindin g mortar unless correctly installed. My frame design permits installation of the glass blocks either at the factory or at a sales agency having men specialized in this particular work and thus assuring a high and `uniform standard of workmanship.

It is, therefore, a primary object of my invention to provide a window frame design combining an upper portion for support of glass blocks with a lower portion having a conventional slid# ing Sash. i

A further object of my invention is to provide a simple and economical window frame of sufiiciently sturdy construction that it will support the weight of glass blocks without deflection either vertically or horizontally.

n additional object of my invention is to provide such a window frame which is easy to install.

Additional advantages of my invention will be recognized by those skilled in the building design and construction vart upon readingthe. following specification and studying thev accompanyingy drawings, in which:

In executing the objects and-purposes of my 'invention I havev provided a window construction having a peripheral frame equipped with a horizontal structural member extending across the opening therein. -The upper portion of the opening is closed by glass blocksl supported by the horizontal member and the lower portion of theopening is closable by a sash vertically slidable to uncover said lower opening and designed to be functionally integral with the entire frame.

In the following description the terms inwardly and outwardly are freely used and are to be taken as inwardly toward the interior of the building when the window is in place, and outwardly away therefrom.' The terms inside and 'outside are to be taken as interchangeable with inwardly and outwardly, respectively. The terms upwardly and downwardly are also freely used an are to be taken as upwardly in the direction of the top of the window as normally installed and shown in Figure 1 and downwardly Ain the opposite direction. The terms upper and lower are to be taken as interchangeable with upwardly and downwardly, respectively.

The frame construction presented in the following description is that of a window utilizing a single frame. However, as is shown in the drawings, the window may be of any size which is a multiple of the basic frame sizesince any number of frames can be set side by side in an 4 opening by the simple expedient of substituting joining plates and bolts, where the frames are contiguous, for the offset plates normally anchoring the frame to the building structure.

Referring to the drawings in detail, the nuimeral I refers to a peripheral frame having a top member 2, side members 3 and a sill member 4. These top, side and sill members are constructed so that a panel of glass blocks 52 may be supported within the upper portion of the opening formed-thereby near the outside thereof, somewhat in the normal position of the upper sash of an ordinary double hung window, and a vertically sliding sash frame 30 may be supported in its lower portion, inwardly thereof, in the normal position of the lower sash of said ordinary double hungwindow.

The members 2 and 3 and the sill 4 may be secured to each other in any convenient, conventional manner, such as by means of the tenons 5 (Figure 9) extending from the upper and lower endsof the members 3 through appropriate mortises in the member2 and sill 4, and upset thereagainst. A more detailed and more fully disclosed example of this type of corner securement may be found in my copending application, Serrial No. 1,220, led January 8, 1948.

The top member 2 (Figure 4) is provided with a sealing flange 9, an offset portion I0 and a plaster key II. The width of the offset portion I0 vis such that a glass, or other similar, block may be freely seated within it. The side members 3 `(Figures 2 and 3) are each equipped with a channel I2 defined on Vvone outward side by a fixed guide I3 integral with the side member 3 and on the other side by a detachable guide 6 (Figure 3). Each of the detachable guides 6 is secured to the side member with which it is associated by means of screws l. The seat portion I4 of the side members is defined by the flanges I5 and I6. VThe flange I6 is an extension of one wall of the fixed guide I3 which extends the entire length ofthe side member `3. The detachable guide 6 is shown as extending the entire vertical length ofthe frame. 'Such construction is not essential -to the operation of my window since the length of. this member need not be more than twice the height of the hereinafter described sash 30. However, the additional length shown (Figure .4) is desirable from an esthetic standpoint.

The sill memberk 4 consists of an inclined portion Il, step I8 and ridge I9. Ribs 20 extend ,downwardly from the lower side of the inclined portion Il to reinforce the member against upward or downward, lateral deflection.

At a point spaced substantially above the sill member 4 a beam 2l (Figures 1 and 4) extents between the side members 3 parallel to the sill member 4. The beam 2|, in cross section, consists of a horizontal plate 22, a downwardly directed vertical flange 23 secured along the inside edge of said plate and having an upwardly and inwardly extending hook 24 projecting from the lower portion of said fiange 23, but spaced from the end thereof. Relatively short ribs 25 project upwardly from the horizontal plate 22 and relatively longer ribs 26'extend downwardly from said plate 22. A downwardly inclined flange 21 is provided along the outside edge of the horizontal plate 22. vThe ribs 25 and 26, the inclined flange 2I and the vertical fiange 23 serve primarily to increase the moment of inertia of the beam 2| to reinforce it against bending loads. The ribs 25 also function, respectively, as a mortar lock. v 1` The beam 2I is installed in the peripheral frame l by means of the tenons 28 (Figures 7 and 8), which are inserted through the mortises 29 in the side members 3 and then riveted over to grip rmly the side members 3.

The sash frame 30 (Figures l, 3 and 4) consists of a top rail 3l, side rails 32 andV bottom rail 33. The top rail 3l has a main, box-shaped portion and an outwardly and downwardly extending hook 34. The side rails 32 each consist of a sub- `stantially U-shaped channel having its open side facing directed toward the adjacent side members 3 of the peripheral frame I. `The bottom rail 3-3 consists of a substantially U-shaped channel having its open side facing directed toward the sill member 4. The outside leg 35 o f the bottom rail channel 33 is longer than the inside leg. Integral with the bottom rail 33 is an upwardly and inwardly extending handle 36. The rails of the sash frame, where they join at the corners (Figure 6), are mitered and the resulting joint is welded, or otherwise suitably fastened, to pro- L A corner member 31, ex-

into the opening 38 it firmly engages the walls of the opening.

The sash frame is preferably suspended upon a pair of conventional, metal sash tapes 39 (Figure 4) resiliently supported in any convenient manner upon said peripheral frame I, above said sash frame.

This brief mention of said tapes 39 is presented only for the purpose of completeness and is not intended to limit the invention.

A transparent or translucent panel 42 made from any suitable material, such as glass, may be held in place within the frame 30 by a suitable caulking means 43, such as putty or a rubber gasket, and a glazing bead 44 (Figure 3) bearing on the putty or gasket and anchored to the sash by a clip 45 on each of the rails of the sash. The glazing bead 44 is further held against accidental disengagement by means of the screws 8. A weather strip 46 (Figure 3) is mounted on the channels of each of the side members I2 and bears against the side rails 32 when the sash frame 30 is in place. A U-shaped weather strip 41 (Figure 4) is mounted within the hook 34 of the top rail 3|. A V-shaped weather strip 48 is seated within the open end of the bottom rail 33, for engagement with the step I8 of the sill member 4 when the sash frame 30 is closed.

Although the various individual parts constituting the structural portions 0f the frame I, including the beam 2I and the sash frame 30, may be made from any suitable metal, said parts are preferably fabricated from aluminum because' of its resistance to corrosion, suitability for complex extrusions and pleasing appearance.

The glazing bead 44, side rail weather strip 46, meeting rail weather strip 41 and sill weather strip 48 are each formed from any suitable resilient material, such as spring-bronze or stainless steel. Other materials may be used so long as they have sufficient resiliency. The resilience of the material both aids in anchoring the parts into place and causes them to bear against the adjacent part of the window structure to effect a sealing action.

A screen 49 (Figure 4) of any suitable design is positioned within the opening ybelow the beam 2| and exterior of the sash frame 30. andis held in place by the slides 50. The screen nests against the inside face of the flange 23 of the beam 2|, and against the flange I 6 on each of the side members 3.

The opening above the beam 2l is closed by a panel of glass blocks 52 supported upon the beam 2I. The blocks may be bound to each other in any suitable manner and are seated at the lower edge of the block panel on the mortar or grout 53. Along its sides and top, the block panel is received into appropriate channel shaped seat portions I4, above described, of the side frame elements 3 and the offset I8 of the top frame element 2. To permit the glass blocks to expand freely with respect to the frame, substantial space is provided between the edge of the block panel and the adjacent surfaces of the frame elements, which space, to prevent drafts, may be lled with a resilient material 55. lSaid resilient material may be anything suitable, such as a fibrous glass insulation. The sealing flange 9a of .the top member 2 and the flanges I5 of the side members 3 project into the opening containing the glass block panel suiciently to enclose and hide the expansion strip 55 and prevent outward movement of the blocks 52. The inward wall of the offset I0 and the upper portion of the vertical flange 23 of the beam 2I limit inward movement of the glass blocks 52.

Any suitable and convenient structure may be used to anchor the frame I to the building strucafs structure 56 by a screw 59.

v'the exterior.

Where the opening requires more than one -frarne unit, as illustrated in Figure 1, two or more frames are mounted sideby Side, each being vanchored at its top and bottom to the building structure in the same manner as if it were a single frame window. One side of each of the outside frames is anchored to the building structure. Where the frames abut each other, the joint between the frames is covered by a plate 60 (Figures l2V and v3) on the interior, and finish strip 6I on The plate 6U and nish strip 6I are held in place by bolts 62. A bolt 63 (Figures l and 2), which is preferably positioned near the upper edge of the window, may be provided for engagement `by the safety belt of a person cleaning the Window, and in this embodiment it performs no other function. The plate 60, finish strip 6I and bolts 62 serve to keep each of the frames in alignment.

The window frame assembly, with or without the glass blocks, is mounted in a suitable opening in a building structure 56 and the offset plates 51 are attached to mount it rmly into position. At the time of installation the sill is placed on fresh concrete or grout 40 in order that the ribs 20 may penetrate the mixture and rmly anchor the Window frame in said concrete when it has set. The gap existing around the window frame is then closed by means of bricks, mortar or plaster, whichever material is used to complete the particular wall structure and give a finished appearance thereto.

The sash 30 is mounted in the frame I by removing the detachable guide 6 and placing the sash against the xed guide I3 and replacing the detachable guide 6. As so mounted, the sash may slide vertically between the guides. As the sash 30 is opened it slides upwardly past the beam 2| and the glass blocks 52 and in open position, resides inwardly of and parallel with said panel of glass blocks. The sash, in raised position is supported by the sash tapes 39. A latching device may be added to the window;` however, suchadditions are optional and since they form no part of my invention they are not illustrated. v V 1 If constructed as above described, the. Il PDer part of the window is sealed against drafts and, .being of glass blocks, requires .little or vnoymaintenance, although the full benefit of daylight is obtained. At the same time the lower part ol the window may be opened in case of an emergency or for purposes of ventilation. By conv structing the dual type window as an integrated unit, the proper coordinated functioning ofeach portion is assured and the installation rendered simple and rapid.

A modication of my window structure (Figures 10 and 11) can be obtained, withcertain advantages being thereby sacriced and others attained, by replacing the vertically sliding sash frame 30 with a hinged sash |00 which is hinged along its lower edge within the frame I upon the window sill member |09 by means of hinges |0|. l

The detachable guides E5 as well as the metal sash tapes 39 may then Ibe eliminated. The side weather strips |02 (Figure 11) are redesigned to fit, and are secured to, the side members 3 wit-hin the channels I2 (Figure 11) for cooperation with the side rails 30. The upwardly extending portion of the hook 2liV (Figure 4) on the beam 2| is eliminated to leave a horizontal, inwardly extending arm |03 on the beam |06 (Figure 10). An outwardly opening channel |04, having flanges hooked toward each other along their free edges, is provided along the top rail |05 of the hinged sash |00 for Vreceiving the arm.|03 directed toward the beam 2|. Any eiective latching device may be used to retain the sash in closed position. A latch of suitable construction (Figure 10) may consist of a base |08 secured t0 the beam |06 and a' lever |97 pivotally supported upon the base |08 for engaging the top rail |05 of the sash |00.

The lower rail ||0 of the hinged sash |00 is so designed that when the sash |00 isv moved about the hinge |0| the rail I0 will not interfere with the guide I3. The sill |09 of the peripheral frame is modied by reducing the height of the ridge and thereby lowering the pivot point of the hinge |0|, A weather strip I2, held in the lower part of the hinged sash, presses against the sill |09 when the sash |00 is in, closed position.

VWhen the window is modied to utilize a hinged sash construction the hinged sash may either be positioned inwardly of the glass blocks 52, as shown, or be placed beneath the glass blocks. If the latter construction is employed, then the width of the frame can be reduced to eliminate the portion previously used to provide rspace for the sash to slide upwardly past the glass blocks. Whether or not the width is reduced, it is optional whether the pivoted sash is hung from the the side members 3. lIn' each case some modif cation of the latching V,structure may be necessary to accommodate the existing circumstances. V

Other variations and modifications will be apparent to persons acquainted with equipment of this general type and the problems and` design thereof; however, each of these'variations and modifications are embraced within the general scope of my invention and will accordingly be included within the purview of the hereinafter appended 'claims excepting as said claims expressly provide otherwise.
