Application October 4, 1957, Serial No. 688,211

'1 Claim. (Cl. 20-52) This invention relates to a split jamb window unit.

An object of the invention is to facilitate the installation of window units by providing a split jamb unit capable of adjusting to suit various window openings. My window unit is made in two sections, the outside is first installed with the weather stripping and then the inside is made and they are put together to form a complete window unit.

It now requires 30 to 45 minutes to install and trim out one window. My window unit can be installed in about three minutes. The great advantage of a window unit constructed in accordance with my invention is that it will adjust to any size wall. Where there are different jamb sizes my window unit will open to take care of the wall. The necessary advantages flowing from the invention are the saving of time, effort, money, millwork, paper work, etc.

Another object of the invention is to provide a split jamb window unit which is capable of being constructed as a single window, a double window, a triple window or any multiple window, it making no difference whether the window is a two light or more. Moreover, the principles of my invention can be practiced not only with wooden windows but with metal windows with practically equal facility.

Other objects and features of importance will become apparent in following the description of the illustrated form of the invention.

Figure 1 is a perspective view of a window constructed in accordance with the invention.

Figure 2 is a sectional view taken on the Figure 1.

Figure 3 is a transverse sectional view of the window in Figure 1.

Figure 4 is an exploded perspective view of the split jamb of the window of Figure 1.

Figure 5 is a fragmentary sectional view showing the mullion, parting strip and other structure that will be used in a double, triple or other multiple window.

In the accompanying drawings there is a window which is constructed in such a manner as to exemplify the principles of the invention. The window is of the double hung sliding sash type and has an upper and lower window sash 12 and 14 respectively which may use sash weight or what is now more common, spring torsion brakes 16 on opposite sides of the window members. Window 10 is set beneath header 20 and has a header cornice 22 nailed to it beneath the drip cap 24. Side casing 26 has members 28 and 30 on opposite sides of the window opening and above the sill 32. Head blind stop 34 is located behind the side casing and header cornice while the side blind stops 38 and 40 are behind the side casings 28 and 30. Weatherstrip 42 is behind the side blind stops and is nailed or otherwise secured to the window jamb.

The two outside window jambs sides 46 and 48 are constructed the same. Each has a smooth inner surface and a notch 49 and 50 respectively on the outer surfaces line 22 of thereof. The outside head jamb 52 is formed with a smooth inner surface and an elongate notch '54 on the outer surface. The inside jamb is constructed of two jamb sides '56 and 58 which are constructed with smooth outer surfaces and notches 60 and 62 on the inside surfaces thereof. The inside head jamb 64 is constructed with a smooth outside surface and an elongate notch 66 on the inside surface. The notches 66 and 54 are interiitted (Figure 2) and the notches of the inside jamb sides and the notches of the outside jamb sides are interfitted (Figure 3). Accordingly, the inside jamb and the outside jamb may be adjusted with respect to each other in order to compensate for different thicknesses of walls within which the window unit is to be assembled.

The window is trimmed out on the inside by an inside head casing 70 and a pair of inside casing sides 72 and '74 that terminate on the stool 76. Apron 78 is below the stool and attached in the customary way. The inside casing is located in front of the window rails 78 and 80.

As shown in Figure 3 the principles of the invention are applicable to double windows. The same would hold true for other multiples of windows in that the structure shown in Figure 5 would merely be duplicated. Here, the mullion 82 is mounted over the adjacent side blind stops 84 and 86, while a facia strip 88 is at the front of the multiple window. The side jambs 90 and 92 are each made in two pieces and are adjustable with respect to each other in a manner identical to that shown and described in connection with window unit 10. Therefore, the entire multiple window of Figure 5 is adjustable to compensate for differences in wall thickness just as the window unit 10.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be restored to, falling within the scope of the invention as claimed.

What is claimed as new is as follows:

An adjustable window unit comprising an inside casing, an outside casing, a pair of window members movable to the window open and window closed positions and located between said inside and outside casings, inside jambs and outside jambs, said inside and outside jambs having sides and head jamb members, and means interfitting said inside jamb members and outside jamb members and said inside jamb sides and said outside jamb sides with each other so that they are adjustable in order to compensate for different thicknesses of walls, weatherstripping for both window members permanently attached only to the outside side jambs in sealing engagement therewith so that the inside side jambs may be adjusted without adjusting the Weatherstripping, and the window members movable in said Weatherstripping.
