sen Corporation, nesota Minn., assignor to Ander- Bayport, Minn., a corporation of Min- This invention relates to casing construction for window and door units and particularly to improved window units having interior trim strips which are adapted for use with walls varying substantially in thickness in relation to the depth of the jamb members of the window frames.

In the manufacture of window and door units economies in the cost of the finished buildings are effected by performing a maximum number of cutting and assembling -operations at the mill. However, under present methods of standardization the exact thickness of the wall where a particular unit is to be installed is often unknown by the manufacturer, or changes in the wall construction may be made after the millwork has been completed. An important factor is the type of interior wall construction. The most common variables result from the choice of three wall types of different thickness. For example if lath and plaster is provided it will be approximately threequarter inch thick, whereas the choice may be sheet rock or other wallboard of one-half inch thickness, or other thinner wall boards of nominal three-eighths inch thickness. If lath and plaster walls are used the interior wall surfaces may be either ush with the inner edges of the window jamb and head members or in other installations may cause the wall surface to project inwardly from relatively shallow window frame members. Otherwise, when the thinner interior wall sheathingis used the window side and head jamb members usually project inward from the adjoining wall surfaces. Since the interior casing members must cover the joints between the window frames and adjacent wall surfaces it has been common practice to leave the cutting and fitting of these interior trim members to time consuming fitting by skilled Workmen during the building construction. This expensive fitting is substantially eliminated by the present invention.

It is, therefore, an object of my invention to make it feasible to precut and lit at the mill or factory substantially all of the members of window and door units including interior casing members which are adapted to compensate for the common variations in thickness of interior wall sheathing.

A particular object is to provide interior casing members which are adapted to be precut to t a particular window unit and to be adjusted to t walls of varying thickness as a result of a novel formation of the individual casing members which permit them to be not only reversed end to end and side margin for side margin, but also placed with either of their longitudinal sides in contact with the wall, depending upon the relative location of the wall surfaces and inner edges of `the window jamb members in each installation.

A further object is to provide casing members each having opposite longitudinal sides which are so molded as to impart simil-ar or compatible appearances irrespective of which side is exposed to view and having relatively thick and relatively thin longitudinal edge portions and parallel, relatively narrow marginal surfaces extending at both sides of the edge portions for contact with the wall and jamb and head frame members.

The invention also includes certain other novel features of construction which will be more fully pointed out in the following specification and claim.

Referring to the accompanying drawings which illustrate, by way of example and not for the purpose of limitation, a preferred form of my improved window casing construction:

Figure 1 is an inside elevationalview showing a window unit of the double hung sliding sash type, with my improved interior casing members in place thereon;

Fig. 2 is a horizontal sectional view taken on the line 2-2 of Fig. l, showing one of the side casing members and adjacent frame and wall members;

Fig. 3 is a vertical sectional view taken on the line 3 3 of Fig. l, showing the top and bottom casing and frame members;

Fig. 4 is a horizontal sectional View similar to Fig. 2 but showing the invention as applied to a wall having interior wall board and wherein the jamb members project inward from the plane of the adjacent wall surfaces, and

Fig. 5 is a vertical sectional View similar to Fig. 3 showing one of my improved trim strips in engagement with a head frame member which projects inward from the adjacent wall surface.

My improved interior casing members comprise a pair of normally vertical trim strips indicated generally by the numeral 6 and a normally horizontal trim strip 7 of similar cross sectional shape adapted to extend across the head jamb member of the window frame. Each of the members 6 and 7 has a relatively thick longitudinally extending edge portion 8 and a relatively thin edge portion 9 extending along the opposite edge. Edge surfaces of the portions 8 and 9 are preferably parallel one to the other and substantially at right angles to adjoining nar-y row, flat marginal surfaces indicated respectively by the numerals 10, 11, 12 and 13. The marginal surfaces 10 and 11 at one side of each strip 6 and 7 are disposed substantially in a common plane and a relatively wide in tei-mediate curved portion 14 merges gradually into the marginal surfaces 10 and. 11 and is generally concave in shape. At the opposite side of the trim strip the marginal surfaces 12 and 13 are offset laterally one from the other approximately three-eighths of an inch and are connected by a relatively wide intermediate curved surface 15. A portion of the surface 15 adjoining the surface 12 is convex and a portion adjoining the surface 13 is concave.

My improved interior casing members are adapted for use with window units of many vdifferent types and having frames of various depths from front to back in relation to the thicknesses of the walls in which the Window frames are used. As shown, the window frame has a pair of side jamb members 16, one at each side of the window opening, a head jamb member 17 extending across the top of the frame and a sill 1S of common or suitable construction extending across the lower side of the window opening. Also shown is a stool member 19 of common type extending above an apron 20 of the i11- terior casing. The inner face of this apron is defined by a curved surface which matches or is compatible with the curved surfaces formed on the inner and outer sides of the trim strips 6 and 7. Upper and lower sashes are indicated generally by the numerals 21 and 22 respectively.

At the mill or factory the ends of the trim strips 6 and 7 may be mitered, as indicated at 30 in Fig. l, or cut with square ends to fit the several window units. This casing construction is adapted for use with conventional or suitable lbuilding structures which may include walls having studding members 23, outer sheathing 24, outer casing members 25 and other suitable rough framing members such as those indicated at r`26 and 27 in Fig. 5.

At the inner side of the wall the sheathing or covering members may comprise vmembers of various thicknesses. For example, as shownfinFigs. 'Zand 3, the-interior wall includes lath and plaster, usually approximately threequarter inch thick, which may have `its inner surface either approximately ilush with the inner edge surfaces of the side jamb members-16 and head jamb members 17, or in a ,plane which is offset outward or inward from the Window frame. When the wall surface is iiush with the frame members the 'trim strips 6 and`7 are placed with their surfaces and 11 toward the wall and in cont-act respectively with the inner surface of the plaster -wall 28 and the inner edge surfaces of the .jamb members 16 and 17. By reason ofthe curvature of lthe surfaces 'A14 and and their. gradual lmerger into the narrow marginal surfaces 10, 11, 12 and 13, the trim strips may be rocked relative to the wall and .jamb surfaces to compensate for the smaller misalignments or variations in the relative positions of the inner wall surface and jamb members.

Forother situations, such as that indicated in Figs. 4 and 5, the trim strips may be adjusted to close the joint between the window frame members and interior wall members 29 having their inner surfaces offset outward as much as one-half inch from the inner surfaces of the jamb members 16 and 17. For this condition the trim strips 6 and 7 are merely placed with their surfaces 12 and 13 in contact with the edges of the jamb members and wall surface adjoining the jamb members, as indicated -in Figs. 4 and 5. This adjustment may require the turning of the top trim strip 7 end for end land inside out and the shifting of the side trim strips 6 from one side of the window to the other and inside out.

In still other situations, the inner surfaces of the jamb members may be offset outward from the adjoining wall surfaces. To meet this condition, the trim strips maybe inverted by merely turning them end for end relative to the positions indicated in Figs. 4 and 5. Thus the offset surfaces 12 of the strips 6 and 7 may be placed in contact with the inner edge surfaces of the window jamb members where Ithe latter are offset outward one-half inch, more or less, from the inner surface of the wall.

Many window units are provided with j'amb extension members or blind stops extending along the inner edges of the main jamb members to increase the depth of the frame. These extension members and stops are so located that they constitute the jamb members to which the casing members are secured. Thus my improved trim strips may be secured in overlapping relation to such jamb extension members or stops as Well as to the main jamb members directly as shown in the drawing.

It will thus be evident that the cutting and tting of the several inner casing members including the strips 6 and 7 and other members of the window units may be performed at the mill so that these casing members will fit together accurately notwithstanding variationsn in the thicknesses of the walls in relation to the depth or thickness of the window frames. This adaptability to more complete factory cutting and fitting effects important savings in the cost ofthe building construction as compared with the conventional practice of tting all casing members at the site of the building under construction.
