6 Claims.

The present invention relates to a window structure and this application is a division of my co-pending application Serial No. 105,687 filed October 15, 1936, which has matured into Patent No. 2,188,050 issued January 23, 1940.

One object of the invention is to provide a window structure having a number of improved features, the window being durable and inexpensive from a manufacturing and installation standpoint.

A further object is to provide a window including a sheet metal window frame and wood. sashes, whereby trouble experienced because of the shrinking and swelling of the ordinary wood frames combined with Wood sashes is reduced, and yet a substantially weather-tight window is produced in the form of a unit which can be readily made in its entirety and assembled at the factory.

Still a further object is'to provide a sheet metal window frame having an outer flange for contact with the outer surface of a wall surrounding a window opening in the wall, and having an inner flange between which, andthe inner surface of the wall, retainer elements are interposed, thereby rigidly assembling the Window frame relative to the wall.

Still a further object is to provide in combination with a sheet metal unitary window frame,

wood sashes which are provided with storm sashes supported on and carried by the wood sashes, whereby the wood sashes may be opened when desired without the necessity of additionally opening the storm sashes. I

Still another object is to provide a Window structure particularly adapted for roll screens, the sashes of the window structure being hinged, and means being provided for opening and closing the sashes and retaining them in the desired position, such means being operable inside the roll screen so that the roll screen .does not have to be rolled up in order to operate the window.

Still another object is to provide a latching means for the sash which is operable inside the roll screen.

Still another object is to provide hinging means for the window sashes which is operable to permit easy cleaning thereof.

With these and other objects in view, my invention consists in the construction, arrangement and combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated. in the accompanying'drawings, in which: I

provided with flanges 28 and 22.

weather strip used in connection with my invention.

On the accompanying drawings my window frame comprises in general a sill member S, side jamb members J and a head jamb member If. The sill S in cross section has a level portion I and a sloping portion l2. Ihe head member H i has a downwardly opening or upwardly depressed portion l4.

All four of the members S, J, J and H are provided with outer flanges l6 and inner hooked flanges 18. The flanges l6 are preferably reinforced by strips IEa spot welded or otherwise suitably secured to the flanges l6.

As illustrated in Figures 14 and l6, the upper and lower ends of the side jamb members J are These are adaptedto overlap the ends of the members H and S as shown. in Figures 15 and 1'7, and to be spot welded thereto, whereby a unitary frame of stamped sheet metal is provided after the parts are thus assembled together.

The strips I611 aresomewhat shorter than the flanges .IB and this is for the purpose of permitting the use of angle members 24 to connect the flanges I6 of the four frame members together. The member H is also provided with a drip flange 26 to prevent the entrance of water hehind the upper flange l6 at'the head of the window frame.

The window frame thus far described is adapted for mounting in the window opening in a wall W as illustrated in Figure 3. The window opening is made, of the proper size and fitted with a wood sill 28 having a sill block 30 mounted on top thereof, the outer edge of which is coincident with the outer face of the wall W.

The window frame is inserted into the window opening with the flanges is against that portion of the wall immediately surrounding the window opening, mastic or other sealing agent 32 shown by black shading being used to provide awater-tight joint. The flanges 16 are then secured in position by fastening elements such as screws 34 extending through openings 38 in the flanges and into the wall and the sill block 38.

After the window frame is thus mounted, retainer strips R. are utilized to more rigidly retain the frame in position, and especially the inner edge in position relative to the: inner surface of the wall W. The retainer strips R are angle shaped in cross section and have flanges 38 and 48. The flanges 38 are adapted to be received in the hooked flanges I8, as shown in Figure 18, and then the flanges 40 are swung in the direction of the arrow at to a position against the inner surface of the wall and secured thereto as .by nails 42 (see Figure 3). One retainer strip B may be used for each flange l8'if desirable. The inner surfaces or backs of the flanges l8 serve as a plaster ground, thisflange, of course, extending around the four sides of the window frame.

In association with my window frame I provide wood sashes S comprising the usual rails, stiles and glass panes M puttied in position. In addition to this ordinary construction, however, I rabbet the rails and stiles as indicated at 45 to receive a storm sash SS. I

The storm sash comprises preferably a single pane of glass 48 and a sheet metal frame 58. As shown in Figure 4 a liner. of rubber or the like 52 is interposed between the peripheral edge of the pane 48 and the. metal frame 58.

The storm sash SS has a finger clip 54 at its upper edge for convenience in supporting it while placing it in position relative to the sash S or removing it therefrom.

For retaining the storm sash SS in position, I provide retainer buttons 56 which are pivoted to the sash S as by screws 58 and may be swung to positions either overlapping or out of alinement with the storm sash frame 58, as shown by full and dotted lines respectively in Figure 19.

By the combination of a sheet metal frame and a wood sash I obtain all the advantages of a wood sash but eliminate the disadvantage of a wood frame combined therewith, and which disadvantage consists of binding of the parts due to swelling of both the frame and the sash. Metal, of course, does not swell and accordingly would retain the same dimensions whether the atmosphere is wet or dry, and therefore only the swelling of the sash has to be contended with. y This materially reduces the trouble experienced by the swelling of wood.

I have also made provisions for the mounting of a roll screenhousing RH by providing the recess l4 in the head jamb member H. The screen is illustrated at 60 and the guides for the edges thereof at 62. A binder bar 84 is secured to the lower edge of the screen 60 and is adapted to be pulled down to a position contacting with an auxiliary sill member S", as shown in Figure 6. Latches 66 are provided for latching the binder bar in this position.

The roll screen housing RH is retained in position by side jamb liners 68 extending from the upper surface of the sill 10 to the under surface of the housing RH. The side jamb liners 68 are retained in position as by screws 10 and serve as side stops for the sash S as shown in Figures 4 and 11. A head stop and a sill stop are provided at 12 and 14 which may be strips of wood retained in position by machine screws 13 and 15 as illustrated in Figure 3.

The auxiliary sill S is also formed of sheet metal and is of angle shape. It has a hooked flange 16 contacting with the sill stop 74 whereby to provide a hollow sill to receive the operating mechanism for the sash, as will hereinafter appear. The auxiliary sill S" is retained in position by the machine screws 15 and additional screws 71. The auxiliary sill S" extends from the inner face of one jamb liner 68 to the inner face of the other. The jamb liners 68 are provided with grooves 78 to receive the screen edge guides 62.

Each sash S is hinged to one of the side jamb members J, as illustrated in Figure 10. The hinge is referred to generally bythe reference character H. The hinge H is of special articulated design to permit easy cleaning of the sash. It comprises a first leaf 80 to which is pivoted a second leaf 82. A third leaf 84 is pivoted to the second leaf-82. The leaves 8|] and 84 are connected with the flange l6 of the side jamb member J and the upper or lower rail of the sash S respectively. The leaves 82 and 84 arenormally latched together by a sliding latch 86 having an enlarged head' 88 normally assuming a position in front of'the end of the leaf 84.

The leave 84 has a slot 98 therein to receive 2,276,729 of Figure 8) is illustrated by full lines, and in its open position for easy cleaning of the sash by dotted lines, the open position of Figure 7 being in excess of the one shown by dotted lines in Figure 10.

When the hinge is opened as in Figure 10 a space indicated at 92 is provided through which a persons arm can be thrust for cleaning the outer surfaces of the sash panes 44.

In Figure 9 the latched and unlatched positions of the latch 86 are illustrated, and it will be noted that when latched, the head 88 enters a pocket 94 in the sash so as not to interfere with the jamb member J when the sash is swung to closed position. A deeper recess 96 is provided for the convenience of the operator in engaging the head 88 with his finger when unlatching the latch.

Incidentally if the latch is left in the dotted position when the sash is closed, it will engage the jamb and be thereby automatically moved to its latched position. The leaf 84 of the hinge is also provided with a finger 85 to aid in the automatic movement of the hinge to latched position. The finger 85 engages the adjacent outer surface of the window frame so that as a position closely adjacent closed position is assumed, the finger 85 being thus engaged with the frame will tend to close the hinge- leaves 82 and 84 relative to each other so that the latch 88 can properly cooperate with the edges of the slot 90.

For opening the sash S without the necessity of raising the screen 68 I provide an operator comprising a crank 98 journalled in a hub I of the auxiliary sill S", and an actuating lever I02. The lever m2 is pivoted at I04 and is provided with worm gear teeth I96. The crank is connected to a worm gear I08 meshing with the teeth I85. The arm I02 is mounted in the hollow space between the sills S and S", as shown in Figure 6, and has on its outer end a roller I III.

The roller III] is adapted to travel longitudinally in a formed channel guide H2 attached to the lower rail of the sash S, as shown in Figure 10. When the lever I82 is swung from the dotted position to the full line position, the roller III] will travel in the direction of the arrow b along the channel track H2 to the full line position where the window is opened. The hooked flange I6 of the auxiliary sill S" is cut away to accommodate the sweep of the arm I02, the terminal ends of this flange being illustrated at H4 in Figure 10.

In order to hold the sash in a tightly closed position, it is necessary to provide a sash latch in addition to the sash operator just described. The details of this latch are illustrated in Figures 4 and 5. The sash has a hook I I6 secured thereto with which a cam flange II8 of a latch lever IZII is ooactable.- In Figure 4 the parts are shown in engaged but not tightened position. Counterclockwise movement of the cam in Figure will pull the hook H6, and in turn pull the sash S tightly against the jamb stop 68.

The handle I has a stub shaft I 22 with which a sector portion I24 of the cam H8 is connected. The stub shaft I22 extends rotatably through a bushing I26 fitted in a bore I28 of the sash stop 68. The back of the sash stop is rabbeted as indicated at I29, the rabbet being of suitable shape to accommodate the hook II 6, the cam H8 and the disk I24. Where the mounting flange of the screen edge guide 62 extends past the hook H6, it may be notched to avoid interference with the hook.

After the window frame is placed in position and the plastering finished, the window may be trimmed in the usual manner, as for instance by applying an apron I30, stool I32, side casings I34, head casing We and finishing mouldings I38 and MI Where a transom type window, as illustrated in Figure 3, is provided, an intermediat head jamb H" is provided, this being of somewhat different shape than the head jamb H and serving the purpose of both a head jamb for the sash S and a sill for the transom sash TS. The recess for the roll screen housing RH is in the form of a pair of flanges I4 extending toward each other.

Where a mullion type window construction is encountered, two of my window frames side by side are used as illustrated in Figure 11.

Due to the window frame being made of sheet metal, it is possible to use a very narrow trim on the window, which has been the modern trend.

My window structure is also readily adaptable to the use of weather stripping. I provide a Weatherstrip W preferably having the cross section illustrated in Figure 20. An attaching flange I62 is adapted to fit in a rabbet M4 of the side jamb liners 38, while another flange M8 of the weather strip W is provided with a central bead M8 and an edge bead IEQ. The central bead M8 is adapted to contact with the outer face of the liner or stop 68 when the window is closed, as shown by dotted lines, while the bead 523 is adapted to be engaged by the sash S when it is closed. By this arrangement, the installer a can actually see whether or not the weather strip is contacting with the sash throughout the length of the strip. If at some point there is nocontact, the strip can be merely 'bent out, giving it more range in springing back as the sash closes.

The flange I42 serves as an anchorage flange, requiring only three or four nails in each strip to hold it in place. This is a decided improvement over weatherstrips of the type to be nailed flat against the outer edges of the stop strips and both prying out of the nails when the sash is closed and which require nails at closely spaced points to minimize gapping open of the strip between the nails. My arrangement also makes it unnecessary to fit the sash closely, as the Weather strip compensates for small irregularities.

Some changes may be made in the construction and arrangement of the parts of my device without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims any modified forms of structure or use of mechanical equivalents which may be reasonably included within their scope.
