WINDOW FRAME` CONSTRUCTION Filed April 17, 1959 wauniwm AN Patented Feb. 27, 1940 UNITED STATES iATENT ,Y vCFFICE` WINDOW FRAME CONSTRUCTION `Noie HirscheypAberdeen, S. Dak. Appt-mation April 17, 1939, serial No. 268,221 v claims. (o1. 21a- 11) This invention relates to building construc-v tions andmore particularly yto the sealingoi frame work dening openings in the walls of lbuildings such as windowl frames. v f

In many building structures and 'particularly in residences, windows and their frames are so constructed that they are rather effectively sealedv against the entrance of air or moisture through the use of weather stripping between the sash and the frame. However, in many types of construction there is improper sealing `of the window jambs or frame elements relative to thewall structure so that there is a good chance for moisture and more particularly wind to enter the wall opening at that point.

One of the objects of the invention, therefore, is to provide a window frame construction in which effective means is provided for sealing the joint between the frame and the main wall structure.

A more specic object of the invention is to yprovide a window frame structure ink combination with a wall structure wherein the usualv building paper which covers the sheathing is in eiTect so arranged that its edge is embedded in or located in thev window jamb and wherein the paper extends from the jamb across the joint between said jarnb and wall.

Another object of the invention is the provision of a window frame structurewherein the parts thereof are effectively yet simply arranged to provide a tightly sealed frame construction and wherein the trim or outer casing can be conveniently applied and 'wherein said casing conceals the sealed jcintformed behind it.

These and other objects of the invention will more fully appear from the following description made in connection with the accompanying drawing, wherein like reference characters refer l to the same parts throughout the Views, and, in

which: i

Fig. 1 is a fragmentary horizontal section through one side of a window frame and a portion of the upper window sash; and A Fig. 2 is a similar view showing a modiiied form of inner trim and finish. In Fig. 1 there is illustrated a window jamb 3 which ,extends vertically at one side of the window opening in the wall, and said jamb is suitably secured in abutment with sheathing 4 which is customarily nailed to vertically disposed studding oneelement of which is shown at 5L The jambf has a window guide strip 6 intermediate its ends which is positioned in a rabvbetedl portion in the outer side face of said jamb.

between these two guides.

. layer of plaster Hi applied to they lathing.

An innerA window guide strip 'l is provided and the lower sash 8 is adapted toslide vertically rIhe corner or junction provided by` thegouterv side and the outer edge face of the jamie is rabbeted as shown in 5 the drawing and receives a "strip of wood or other suitable material which constitutes a blind stop 9- and also serves as a guide for the `upper sash lil which slides between said blind stop and the intermediate window guide' strip ii.

rThe diagonally opposite corner'of the jamb 3 4is rabbet'ed as at ll to? receive the vertical-edge portion 'oi al basematerial such asa sheet of composition board It vand metal lathing litv may be placed. over the composition boardy with a The corner Oi the plastered portion. may be provided with abullnose strip l5.

The outer sheathing 4 in the wall structure is customarily overlaid with a layerA of building 20 paper IB and any suitable vouter `covering or veneer may be placed thereover. In the drawing I have shown the outer finish as comprising metal lathing Il to which is applied a layer of stucco I8. l The vertical edge of the buildingk paper I6 or other suitable fabric extends across the joint between thejamb 3 and the abutting sheathing Il and across the outer edge face of the sheathingv with the extreme edge portion ofthe building 30 paper Ii turned into the rabbeted corner of the jamb which receives'the blind stop 9. After the paper is thus' turned into the` rabbet, the blind stopy is also placed therein and it mayr be secured by driving a nail through the blind stop and through the edge of the building paper into the jamb. An'outer casing or trim strip element l@ may be placed over the building paper and' preferably the outer casingmaterial overlies' the point where the building paper i6 enters the 40 rabbeted portion of the jamb 3 between said jamb and the blind stop. If desired, instead of running a nail through the blind stop and building paper and thence into the jamb, a nail may be driven through the casing element or outer trim strip I9 through the blind stop 9, and thence into the jamb. The construction is extremely simple yet an absolutely tight joint is produced so that l it is impossible for any wind or rain to get inl between the jamb 3 and the sheathing 4.

Inv Fig. '2 the jaznb 3 is. :formed in much the samek manner as in Fig. 1 except that it extends lilo.

casing element I9 is also as shown in Fig. 1.

The inner window guide 20 will be seen to eX- tend inwardly a considerable distance more than v The the inner Window guide strip l in Fig. 1. composition board vI2 is located the same as in Fig. 1 as is the metal lathing I3. The plaster I4, however, extends over to and abuts the projecting portion of the Window guide 2U. Instead of bullnosing the corner of the plaster in this embodiment, I provide an inner trim strip or casing element 2| which overlies the edge of the plaster and forms a slight lap in conjunction with the extended inner edge of the inner window guide 20.

From the foregoing description', it will be seen that I have provided a relatively simple Window frame structure wherein the vertical edge of the building paper is firmly anchored in a vertical rabbeted portion of the window jamb and is retained in said rabbeted portion by a blind stop,

and I also provide anouter casing or trim element Which covers the point Where t'he edge of the building paper extends into the rabbeted portion of the jamb. It is absolutely impossible for any Wind to enter the building between the window jamb and the sheathing 4. Therefore, if the sash is properly weather stripped the resulting structure is such that no wind is admitted into the building as a result of construction in or adjacent the Window Wall opening and there is consequently material saving in heat. The window jamb itself is of. simple structure and the diagonally opposite rabbeted corners thereof provide for easily assembled and extremely tight joints on both the inner and outer faces of-the wall Where they meet the window jambs.

It will, of course, be understood that various changes may be made in the form, details, ar-

rangement and proportions of the various parts said rabbeted portions in their opposed side faces and sheets of building material' extending along edge faces of said jarnbs having vertical edge portions extending into the rabbetedportions of said jarnbs between said jambs and said blind stops, at an angle to said edge faces.

2. In a building construction, a pair of spaced vertical jamb elements having vertically disposed rabbeted portions, blind stops positioned in said rabbeted portions, sheathing material abutting said jambs, and sheets ofA building fabric over-l lying said sheathing and having verticaledge portions inserted in said rabbeted portionsof said jambs between the jambs and said blind stops. I

3. The structure inrclai1n2 andttrirn strips positioned against said building fabric and overlying the place of entry of said building fabric into said rabbeted portion.

4 In a building construction, a pair of spaced jamb elements having interior and exterior side faces and interior and exterior edge faces, said jambe having rabbeted portions at the junction of their exterior edge faces and side faces, blind' stops positioned Within said rabbeted portions,

and building fabric having edge portions terminating in said rabbeted portions between said jambs and said blind stops.

5. The structure in claim '4 vand trim strips f positioned against said building fabric and overlying the points Where said building fabric enters said rabbeted portions.
