Original application January 28, 1948, Serial No. 4,794, now Patent No. 2,663,917, dated December 29, 195B. gsigiled and this application April 28, 19513, Serial No.

4 Claims. (Cl. 189-78) This invention relates to frames for windows, and particularly to a frame of the all-metal type which may be joined together by mullions which extend the frames to cover `any desired length of opening and is a division of my application Serial No. 4,794, now Patent No. 2,663,917, issued December 29, 1953.

The sections of the frame are so formed as to interlock with each other, and screws are provided for joining the frame sections at the corners so that the entire frame may be shipped in knocked-down condition, occupying very little space. Glazing putty may be employed for retaining the panes in position in the frame or spring strips may be utilized for holding the window pane within the frame. The frame is so constructed as to support a single thickness of glass, or two thicknesses of glass or a Thermopane type window glass may be mounted directly into the frame. The said spring strips, which are resilient in construction, are associated with and braced against the panes or closure panels, by means anchored in appropriate longitudinal grooves in the opposing faces of the header, sill and jamb sections of the window frame. Alternatively, the resilient strips and anchor means therefor can be employed with sash frames having longitudinal grooves in the opposing faces of the Stiles and rails thereof. As used herein, the terms centerward and center will have reference to the geometric center of the window frame or sash frame.

Accordingly, the main objects of the invention are: to provide a window made of sections of a metal which are securable together to form the header, sill and jamb sections which are releasably secured together at the corners; to provide removable means for securing closure panels in place within a window frame, said means being anchored upon the opposing or centerward faces of the header, sill and jamb sections of said window frame; to provide removable means, as aforesaid, for securing closure panels, alternatively, within a sash frame, said means being anchored upon the opposing or centerward faces of stiles and rails of said sash frame; and in general to provide a removable means, as aforesaid, and cooperating means therefor on the window or sash frame which are simple to construct, easy to use or install, require no special skills to install or assemble and provide positive holding of closure panels in place with-in said window or sash frame,

Other objects and features of novelty of the invention will be specifically pointed out or will become apparent when referring, for a better understanding of the invention, to the following descr-iption taken in conjunction with the accompanying drawings, wherein:

Figure 1 is an elevational view from the exterior of two window frames in mullion arrangement embodying features of this invention;

Fig. 2 is an enlarged broken sectional View of the structure illustrated in Fig. 1, taken on the line lI-II thereof;

Fig. 3 is an enlarged broken sectional view of the structure illustrated in Fig. l, taken on the line Ill-lll thereof;

Fig. 4 is an enlarged broken sectional view of the structure illustrated in Fig. 1, taken on the line IV-IV thereof.

Referring to Fig. 1, a window assembly of the present invention is illustrated, wherein a pair of frames is disposed in an opening, forming a mullion therebetween. Each frame comprises a header section 10, a sill section 11, jamb sections 12 and a mullion jamb section 13. Within each frame, fixed window panels 14 are supported in offset relation with window sash assemblies 15 which may slide to the left or right in overlapping relation to the xed panes 14, thereby having the window assemblies 15 rnove to open position.

Referring to Fig. 3, the header section 10 embodies a header bar having a web 17 having a downwardly extending portion 18 and an inwardly sloping web por tion 19. A dovetailed recess 21 is located at the junction between the web 17 and portion 18. A downwardly projecting flange 22 is provided on the opposite end of the web from the portion 18, and a similar downwardly directed flange 23 extends from the end of the web 19. A dovetailed recess 24 is provided on the outer surface of the web 17 adjacent to the dovetailed slot 21. This latter dovetail 24 is employed to receive and be secured by a head anchor 25 which is nailed or otherwise secured to the building structure 26. A dual-purpose inner header and sill section 27 is joined to the web 17 of the header section 10 through the engagement of the dovetail 28 thereof in the dovetailed slot 21 of the portion 18. The inner header and sill section is of U shape having an outer web 29 and inner web 31 on the end of which the d-ovetail 28 mentioned above is provided. The webs 29 and 31 are joined by a base web 32 having downwardly presented spaced grooves 33 and 34 therein. The web 29 extends downwardly at 35 below the base web 32.

The side jamb sections of the frame 12 (Figure 4) embody a channel section 36 having a laterally extending web 37 which is anged outwardly on the end at 38. A ridge 39 on the outer surface of the web 37 has an outwardly facing slot 41. The web 37 is disposed laterally of a side web 42 of the channel element 36 having joined thereto the base web 43 of channel portion which is provided with a pair of spaced grooves 44 and 45 which are aligned with the grooves 33 and 34, respectively, of the inner header and sill section 27. An outer web 36 extends from the base web 43 of the channel portion parallel to the web 42 and is provided with an oifset portion 47 having a slot 48 therein aligned with the slot 41 in the ridge 39 in the outer surfaceof the web 37. A ange 49 extends from the offset portion 47 of the web 46. A jamb anchor 51 has a web portion 52 engaged in the slots 41 and 48 from which a web 53 extends in a position to be secured to the frame elements of the building. By reversing the jamb section of the frame element 12 end for end, it may be applied to either the right or left-hand side of the window frame.

The web 46 is extended at 54 below the base web 43 and this web 46 is notched out at the top to receive the web 29 (Figure 2) and extending iiange 35 of the inner header and sill section 27. Thus, the tlanges 54 :and 35 are coplanar.

The sill section 11 comprises a sill bar having a web 58 (Figures 2 and 3) having on the end a downwardly extending ange 59 and inwardly therefrom a flange 61. A portion 62 extends upwardly from the web 5S and has an inwardly extending web 63 which slopes upwardly and which is provided with a track 64 and an upwardly extending lip 65 at the inner end., This lip collects the condensation from the windows and permits it to flow down the slope of the web V63 outwardly of the frame. The trackway has a slotted portion 66 therein which permits apertures to be drilled therethrough to permit drainage, and any burrs that may be left in the hole need not be removed because of their location within the slot. The portion 62 of the section is provided with a pair of dovetailed slots 67 and 68 and a ridge 69 forms a dovetailed slot 71. An Ianchoring element 25 engages the dovetailed slot 71 to anchor the sill in position in the building opening. A similar anchoring element 25 may also be utilized for engaging in the dovetailed slot 68 for anchoring the sill to the building structure. The inner header and sill section 27 is applied to the ange 58 of the sill bar through the engagement of the dovetail 28 in thc dovetailed slot 67. The bottom portion of the inner header and sill section 27 may extend along the sill of either or both of the window assemblies 14 and 15 and may be secured to the portion 62 by screws, as shown in Figure 3.

One end of the section 27 at the corner of the sill abuts against a frame meeting rail 72 (Figure 4), the lower end of which has a laterally extending flange 73 cut away to provide a notch for receiving the end of the section 27. As illustrated in Fig. 3, similar screws are utilized for extending through apertures in the upwardly extending portion 62 on the sill section 11 and secured in threaded apertures on the inner face of the frame meeting rail 72. Spaced webs 74 of the section 72 have outwardly directed spaced grooves 75 and 76 in alignment with the grooves 33 and 34 in the inner header and sill section 27 and with the grooves 44 and 45 in the jamb section 12. The section 72 abuts against the web 17 of the header section and is secured in position by screws extending through apertures in portion 18 into threaded apertures provided in the inner web 77 of the section. A large dovetailed groove 73 is provided in the face of the web 77 for receiving a weatherstrip 79 which is retained in position thereby. Certain of the channel sections 36 of the jamb section 12 may be provided with dovetailed grooves 40 for receiving a weatherstrip 79 which is retained in position thereby to abut the weatherstrip 94 when the movable sash is in closed position.

The sliding window (Figures 2 and 4) has a sliding sash 81 which embodies two like stiles 82, a top rail 83 and a bottom rail S4. The stiles are of tubular form having outer side faces S5, inner webs 86, a glass supporting web 87 and an outer web 88. The glass supporting web 87 is provided with inwardly directed grooves 89 and 91 which are spaced from each other, while the web 88 has an extending flange 92 which projects beyond the web 87. The outer surface of the web 88 is provided with a dovetailed groove 93 for supporting and securely holding a weatherstrip 94. The top rail 83 of the movable sash has a central web 95 with upwardly directed ilanges 95 at each end, the outer surface of which is provided with projections containing dovetailed grooves 97 for receiving the Wcatherstrip 94. A downwardly projecting flange 9S is provided in alignment with the flange 96 on the front face of the top rail.

The bottom rail 84 comprises a central web 99 having downwardly projecting wall portions 101 containing slots 102 for reducing the weight of the section. An upwardly extending flange 103 is provided at the front of the bottom rail, aligned with the flange 93 of the top rail 33 and flange 92 of the Stiles 82. The flange 92 is cut away on the sash stiles S2 to provide notches for receiving the ends of the top rail and bottom rail to which they are secured by screws 104 extending through apertures in the web 85 of the stile and threaded into apertures in the webs 95 and 99 of the rails S3 and 84, respectively. In this manner the sash is securely held together at the four corners.

Rollers 107 have their stub shafts 108 extending through apertures in the webs 86 and 8S s0 aS t0 be in alignment with the track 64 of sill section 11. The screws 104 are disposed on each side of the rollers to assist in maintaining the rollers in alignment with the track. The shafts 108 are peened in the `apertures and the rollers freely turn on the shafts. A roller is mounted in the end of each of the jamb sections 82 of the sash so that both ends ride upon track 64.

A window pane 111 (Figure 4) is mounted against the flange 73 of the frame meeting rail 72, the flange 35 on the inner header and sill section 27 and the flange 54 on the jamb section 12. The flanges above named are coplanar and directly receive the glass. The glass is forced against putty or other sealing material placed on the flanges. Four glazing strips 112 form a coplanar retaining flange around the opening when inserted in the aligned grooves in the inner header and sill section, in the frame meeting rail 72 and in the jamb section 12. Thereafter, four U-shaped spring elements 113 are slipped in between the glass 111 and the strips 112 to urge the glass outwardly against the coplanar flanges. Spring tension in the strips retains the strips and glass in position. The window glass 114 is applied in the same manner to the window sash 15, the pane first being placed against the ange 92 of the stiles and flanges 98 and 103 on the top and bottom rails 83 and 84. Thereafter, glazing strips 112 are placed in one set of grooves to be coplanar with the llanges above mentioned against which the glass is placed, after which four of the spring strips 113 are added between the anges 112 and the window glass 114 to hold the glass in position.

When it is desired to join two windows together, they are assembled in the same manner, with the exception that a frame mullion jamb 115 (Figure 4) replaces the standard frame jamb 12 in one of the windows. This mullion jamb has a channel section 116 having an outer web 117 and an inner web 118 joined by a base web 119 containing spaced grooves 121. The web 117 at the end has an inwardly extending flange 122 and also an offset projecting flange 123. The web 118 has a web 124 extending from the end inwardly at right angles therefrom, which has on its inner'end an enlarged portion 125 provided with a slot 126 for receiving a strip 112 which overlaps the web 37 of the frame jamb section 12. The anges 112 and 123 mate with the ange 49 and web 46 of the frame jamb section 12 and prevent the section 116 from moving inwardly, while the engagement of the portion 127 of the enlarged portion 125 of the mullion section 13 prevents the section from moving outwardly. A leaf spring 128 is disposed between the web 124 and the flange 38 on the section 12 to urge the webs 124 and 37 away from each other but permitting them to move toward each other in case the metal of the frames expands. When the metal contracts, the spring maintains the engagement of the web 37 with the strip 112.

While it is within the purview of this invention to use window panes which extend from the top to the bottom of the frame and sash, muntins can be employed therebetween for using glass panes of shorter height. A section of the muntin is illustrated in Fig. 3 wherein the muntin is the shape of an H having a central web 130 and two parallel webs 131 disposed at right angles thereto and in T relation therewith. This provides yan upwardly and downwardly presented [channel on either side of the web 130 for the reception of the bottom of the top pane of glass and the top of the bottom pane of glass. The external flange 131 of the muntin is cut away at both ends thereof so that the web 130 thereof can be secured, as by screws (Figure 3), to the flanges 73 and 54 of the jamb sections 72 and 12, respectively.

It will be noted when examining the window frame vstructure and the movable sash structure that the adjacent faces which support the window panes 111 and 114 have an additional set of grooves 89, 76, etc. parallel to but spaced from the grooves in which the glazing strips 112 are employed for securing the panes in the frame, as

illustrated. If Thermopane glass is to be employed embodying a pair of spaced window panes, these are mounted in the window opening and ycover the grooves now employed for holding a single pane. The supporting glazing strips are applied to the innermost set of grooves and putty or glazing strips with resilient strips may be employed for holding the Thermopane glass in position.

It is also within the purview of the present invention to apply a pane of glass against the strips 112 and employ another set of glazing strips 112 in the innermost grooves and utilize additional glazing springs 113 for retaining the second glass against the glazing strips 112 to provide `double thicknesses of glass in the openings. The window glass could be of the removable type having a frame (Figure 4) which can be set in the opening against the strips 112 and retained in position through the application of another set of strips 112 in the innermost grooves. In the summer months these latter strips and window may be removed and stored.

It will be noted that the storm or framed window may be :applied directly to the outside iianges 54 and 73 of the frame in the window opening as the distance between the flange 73 and groove 75 of the frame meeting rail 72 is exactly the same as the distance between the face of the strip 112 and the groove 89 of the window sash stile. This is `also true of the distance between the face of the strip 112 and the groove 4S of the frame jamb section 12. The same treatment may be applied to the fixed window, to the movable sash, and also to ldhe window open ing through the frame.

Referring again to Fig. 1, it will be noted that the lefthand and .right-hand windows which go to make up the pair of windows joined by the mullion have the movable sash reversed, that is to say, the sash is on the left-hand side of the left-hand window and on the right-hand side of the right-hand window of the pair as viewed in the figure from the outside of the building. It should be undenstood that the movable sash may be disposed on the left-hand or right-hand side of both of the windows, or both of the sashes could be placed 'adjacent to each other, the construction of the present window readily lending itself to such adaptation.
