3 Claims.

'This invention relates to an improved window frame assembly.

An object is to provide a window frame assem bly ofa unitary structure which is adapted to fit within window openings which may vary slightly in size, without the usual cutting and fitting of parts which is now required to mount a window frame within a window opening and the window sash within the frame;

The assembly comprises a window frame provided with the usual slidable window sash and jamb guides therefor, and also a screen and mounting therefor, and means associated with the frame assembly, and forming a part thereof adjustable to enable the frame assembly to fit within provided window openings which vary somewhat in size.

Window frame assemblies of this character may be fabricated entirely within the factory and shipped as unitary structures and stored as V such until they are required for use. They may be mounted on the job by ordinary labor, and do not require the skilled labor necessary to fit wood sash and wood frames as they are conventionally fitted today.

The construction shown is a composite structure, being formed in part of wood and in part of metal, but the major portion of the structure is formed of shaped metal strips fitted together to define a window frame exhibiting jamb channel guide portions, a header portion, a sill portion, and adjustable jamb header and sill strips which are carried by the frame assembly but adjustable relative thereto, and adapted to be secured to the frame of the window opening to mount the frame assembly therein.

A meritorious feature is that the construction 2 tures will more fully appear from the following description, claims, and accompanying drawings, wherein:

Figure 1 is an inside elevation of a window opening in a building provided with my improved assembly.

Figure 2 is an enlarged broken vertical sectional view taken on the section line 2-2 of Figure 1.

Figure 3 is a broken horizontal sectional view taken on the section line 3-3 of Figure 1.

Figure 4 is an enlarged fragmentary vertical sectional view through the lower sash portion of the frame assembly.

Figure 5 is an enlarged fragmentary horizontal sectional view showing a modified form. of screen sup-port.

Heretofore in the mounting of a window frame within a window opening, and in the mounting of window sash within the frame, it has been common practice'for a carpenter to fit each frame to its opening. The frames are of standard size, and the openings are so formed, but the frames do not fit the openings closely enoughto make a good joint, and fitting on the job has been necessary. Unless the window sashes were mounted within the frame in the factory, it was necessary that they also be fitted on the job. This is painstaking, accurate work which it is diflicult is built up of simple, inexpensive, easily assembled metal strips so fastened together as to make a unitary frame assembly and so provided with adjustable sealer strips as to be capable of being mounted and fitted within a window opening and forming a tight seal therewith.

In the preferred construction shown, the assembly includes upper and lower sliding sash mounted within the window frame for raising and lowering. These sliding sashes are formed of metal and a metal frame screen is associated therewith and adapted to be interposed across the space normally closed by either sliding sash. The frame assembly is so constructed that either sliding sash may be removed for glazing or the like without disassembling the other portion of the frame.

Other objects, advantages,and meritorious feato obtain under present conditions, and it is costly to accomplish. Metal window frame assemblies have heretofore been provided, but upon mounting the same in a window opening it was necessary to fill in around the metal frame to make it fit the window opening. The construction of this application is such that adjustable parts are provided which are readily shiftable to adapt the frame assembly to fit window opening; which vary somewhat in size, and to form a close joint and seal therewith.

The window opening within which my improved assembly is to be mounted is shown in a building having an outer brick wall, and is defined by a header portion ID, a sill portion 12, and

opposed jamb portions [4. These window openings though designed to a certain dimension will made up of a header portion [8, a sill portion 20, and a pair of opposed jamb portions 22, all secured together to form a substantially rectangular frame with the ends of the jamb portions projecting at the bottom as shown in Figures 2 and 4. To each of the jamb portions 22 there is secured a metal jamb guide member having a part 24, which over-laps the inner face of the jamb portion 22, and is secured by screws 26 thereto. ,This guide member is shaped to provide a part 29. which over-hangs the outer face of the jamb portion 22, and to define a pair of sash guide channels 28, as shown in Figures 3 and 4.

Each of these guide members 24 is made in two parts, namely, an upper portion for the upper sash, and a lower portion for the lower sash, which facilitates independent removal of the sashes. The portion 29 of this member which over-hangs the outer face of the wood jamb '22,

is spaced therefrom so as to provide a recess therebetween, extending longitudinally of the jamb portion, and. within which a jamb sealer strip 30 is slidably received. A pair of these jamb sealer strips are mounted within this recess, as shown in Figure 1. They over-lap at their meeting ends so as to provide for adjustment longitudinally within the recess. They are slidably adjustable laterally in and out of the recess to bring the outer flange 32 of each strip into engagement with the jamb portion i i of the window opening.

It will be seen that when this window frame assembly is mounted within a window opening, these jamb sealer strips may be slidably adjusted to be brought into contact with the jamb portions Id of the opening and screws 34 may be passed therethrough and into the inner stop It to position and support the window frame assembly within the opening. Thesescrews are shown particularly in Figures 3 and 5. They are there shown as extending between the wood jarnb portions 22, and the flanges 32, but the screws may cut through the wood jamb member if desired.

Upper and lower window sash 36 and 38 are provided. These are slidably supported within the guide channels 28, hereinabove described. These sashes are here shown as metal sashes provided with glass panes. Comparable metal sashes. are shown in my pending United States application for patent, Number 592,340, filed May '7, 1945, now Patent 2,525,322, granted October 10, 1950. Thetop rail of the lower sash is provided with a screen supporting ledge. 40, and the bottom rail of the lower sash is shown as provided with a screen retaining ledge 42, hereinafter more specifically described. This invention concerns the frame assembly and its mounting within the window opening and not the details of the sash structure.

- There is a header element which has a part 44, that is secured by screws or the like 46 to the wood header [8. This header element is bent upwardly to over-lie the outer face of the wood header I8, and to form a downwardly open channelportion 48 which over-hangs the guide channels 28 of the jamb guides and receives the upper rails of the sliding sashes. upon the'wood header I8 is a header element 50. This header element is of channel formation and is received over the header element 18, as shown inFigure 2. This element 50. is adapted to be secured by nails 52 or the like to the header portion of the window opening. It is provided withan outwardly projecting weather protective Slidably mounted lip 54 adapted to rest upon the top of the channel portion 48 heretofore described, and as shown in Figure 2.

There is a sill member which has a part 56 that extends over the inner face of the wood sill 20 and may be secured thereto by nails 58. This sill member is bent as at 60 to over-lap the outer face of the wood sill 20 and is spaced therefrom to provide a recess therebetween. This sill member is also shaped to provide a shoulder portion 62 which extends'across and underneath the sash guide channels 28. The portion 62 is "then bent downwardly as at 64, as shown in Figures 2 and 4.

There is a sill sealer strip 66 which is slidably received underneath the margin of the part 64 and between the part 60 and .the wood sill 20, so as to be snugly supported, and is slidable up and down to have its weather protective lip portion as brought into engagement with the sill portion l2 of the window opening. Screws 10 may be used to fasten this sealer strip in place.

It will be seen that each of the sealer strips, namely, the sill sealer strip, the header sealer strip, and the two jamb sealer strips are each slidably associated with the window frame assembly. Each is adapted to be secured to a part of the window opening to position the frame assembly therein. They also hold the frame assembly therein. The lower projected ends of the wood jamb portions 22 are cut off to the proper length, so that when the wood header portion is is received within the channel of the header element 50, as shown in Figure 2, such lower ends will rest upon the sill portion 12 of the window opening.

It is recognized, however, that the seal formed at top and bottom between the window assembly and the window opening, is formed by the header element 5!] and the sill sealer strip 66, respectively. It is also understood that the jam-b sealer strips 30 are not only adjustable in and out laterally, but are adjustable linearly of the window opening, so as to provide an effective seal.

The sil1 of the window frame assembly is also provided with a member 72 which may be secured thereto by nails T4 and which has a part 16 that is bent to slope outwardly and downwardly, as shown in Figures 2 and 4. This sloping part is adapted to retain a screen such as is shown in Figure 4, and indicated by the numeral 78 in place. In such figure a metal screen is shown as resting at the bottom upon the sill member 56, of the frame, and as having its upper margin received underneath the downwardly and outwardly extendingscreen retainer flange 42 of the upraised lower sash. An angle strip 80 is also secured to the wood jamb portions 22 by the screws 26. This strip has a face portion 82, shown in Figures 3 and 5, against which the screen 18 is adapted to rest when it is disposed underneath an elevated sash, as shown in Fig 1. A window frameassembly. adapted to be received within the margin of a window opening 7 comprising, in combination, a rectangular window frame structure including a rectangular wood frame made up of a pair of jamb portions, a header portion, and a sill portion, a sash guide member secured to each wood jamb portion and having a part defining a pair of parallel sash guide channels offset laterally of the wood jamb portion, a channel guide for a screen telescoped over the back of one sash guide channel and having one leg disposed between the two adjacent side walls of the two sash guide channels, said screen guide having a width greater than the width of the sash guide channel telescoped thereby and providing a third parallel channel disposed laterally beyond the two sash guide channels and providing a guide channel for a screen.
