l2 Claires.

An object of my present invention is tov provide a frame construction, especially one for a window, having novel characteristics of construction and which may be manufactured inexpensively,

A further object is to provide a stop on a frame which is limited automatically in its location, so that a minimum dimension may be established between the stop and another one between which a sash, for instance, slides.

A further object is to provide a jamb with a liner strip which serves the purpose of adapting the frame to dilierent kinds of wall constructions and thicknesses and which so coacts with the janib that a bead is formed tc serve as a limiting means for the position of a stop.

Still a further object is to provide a jamb and a liner strip with their edges rabbeted together, such edges being of diiierent thicknesses whereby to form a shoulder on the inner face of the jamb against which a port ion of a stop strip may engage for limiting lateral adjustment of the strip.

Still a further object is to provide a stop strip having a groove on its face which engages a jamb, one side of the groove being adapted to engage a bead or other projection on the jamb and the groove being entirely concealed when the stop strip is in applied position on the jamb.

Still a further object is to provide a bead and groove connection between stop strips and side jambs and a rabbeted connection between a stop strip and a head jamo, so that after the head and side jambs are assembled, the stop strips can be applied to the side jambe and the stop strip can then be applied to the head janib.

With these and other objects in View my invention consists in the construction, arrangement and combination of the va-rious parts of my device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawing, in which: t

Figure l is a horizontal sectional View through the side jamb I" a window, showing a liner strip applied thereto and the frame built into a masonry wall.

Figure 2 is a similar sectional view showing the frame in a brick veneer wall.

Figure 3 is a similar sectional View showing an eXtra thick masonry wall with a subjalnb replacing the liner strip of Figures l and 2.

Figure 4 is a sectional view somewhat similar to Figure l, showing another type of liner strip and showing a stop strip applied to the window jalnb.

Figure 5 is a sectional view through a head jamb of a window frame of the type shown in Figure 4, illustrating the liner strip and stop strip applied thereto; and

Figure 6 is a perspective view of a portion of a side jamb, a liner strip and a stop strip.

Referring to Figure 1, a side `iarnb ls indicated Serial No. 594,575

at lo. The inner edge of the side jamb 10 is rabbeted as indicated at l2. A liner strip A has a tongue 14 to engage the rabbet l2.

1t will be noted that the surface 16 of the liner strip A is shorter than the surface 18 of the jamb 10. This provides a shoulder at 20. In order to make the shoulder 20 in vthe form of a bead 22, the janib 10 is depressed at 24. Thus the top of the head 22 does not project beyond the inner surface of the jamb 10 so that the jamb can be more readily machine formed and thinner lumber may be used to form it.

The liner strip A is provided with a groove 26 and a flange 28. The groove 26 is adapted to receive lath 3o and plaster 32 of a wall covering of the wall in which the jamb 10 is mounted. The flange 28 overlaps the lath or other covering 30.

It will be noted that the linervstrip A may be used with masonry, as shown in Figure 1, studding being shown at 34 and a urring strip at 36. The liner strip A may also be used in a brick Veneer wall, as shown in Figure 2. The brick veneer is shown at 38 and furring strips, insulation or the like 40 may be interposed between the studding 42 and the brick veneer so that the jamb 10 actually sets farther out with respect to the studding than it does in Figure 1. In Figure 2, lath 44 projects into the groove 26 of the liner strip A and the inner wall is faced with plaster 46.

As shown in'Figure 3, where extra thick walls, such as of masonry are used, a subjamb or jamb extension 48 may replace the liner strip A. The subjamb 48 has a tongue 14a and a surface 16a corresponding to the tongue 14 and surface 16 of the liner strip A. Thus the bead 22 projects and forms a shoulder 20, the same as in Figures l and 2.

An inspection of Figure 4 makes it obvious that the shoulder 20 is adapted for limiting the adjustment ci an adjustable stop B toward a window sash or toward the center of the jamb l0. The stop B has a groove 52 wider than the bead 22 so as to permit adjustment of the stop strip toward or away from the sash 50, but its adjustment toward the sash is positively limited by the bead. Adjustment is made possible by securing the stop to the jamb l@ with screws 54 extending through enlarged openings 56 of the stop strip B.

In Figure 4 and also Figure 5, a liner strip A is illustrated for a narrower wall, such as one of siding or shingle type. The strip A has a tongue i417 and an edge 16o corresponding to these parts in Figure 1, but the strip is much narrower and the groove 26 is eliminated. The flange 28, however, is retained and the tongue 14h is made narrow enough to provide a groove, the sides of which are indicated at 58 and 60 and the bottom at 62.

The side 58 is formed by the rear edge of the jamb l0. In Figure 5, I have illustrated a head jamb a with the liner strip A associated therewith. The head jamb, however, does not have a bead 22, but instead has a rabbet 64. A stop strip B (which may or maynot be grooved like the strip B) engages the rabbet 64 to limit the adjustment of the stop strip toward the center of the jamb 10a, adjustment being retained by screws 54a, through enlarged openings 56. The rabbet is used on the head jamb because it simplifies machining and facilitates application of the liners. If a rib were formed on the head jamb it` would either have to be cut off at its ends adjoining the side jambs or the top ends of the liners on the side jarnbs would have to be notched to fit over the rib.

The liner strip A or A provides additional nailing surface for the trim 66 as well as providing for coaction of the inner wall covering with the jamb 10 (the liner strip being a portion of the jamb when secured thereto). It was found in practice that the mechanic or carpenter in applying the stop strips B would set them too close to the sash with the result that the sash would not slide easily. The shoulder 20 of the bead 22 engaging one side of the groove 52 therefore predetermines the amount of channel clearance between the stop B and the center stop 68 (see Figure 4) of the window frame so that the sash will slide easily at all times and in all positions of adjustment of the stop strips.

The groove 52 being wider than the bead 22, however, permits adjustment of the stop away from the sash, if desired. The stop B having a groove 52 rather than a projection of any kind makes it possible to easily sand the stop strip at the factory.

Some changes may be made in the constructionV 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.

I claim as my invention:
