Application December 7, 1953, Serial No. 396,389

1 Claim. (Cl. 2011) This invention relates to architectural trim, and it has particularly reference to a shell or covering for wood trim about window and door openings, cornices, and the like, and its principal object resides in the provision of a protective and ornamental cover for window and door facings, headers, sills, and other similar trim, which can be formed of sheet metal, such as aluminum, plastic, and other suitable materials, by which ordinary painted wood trim can be permanently protected against deterioration and rendered more attractive in appearance, obviating the necessity for refinishing from time to time.

- A further object of the invention resides in the provision of an economical device by which existing frame structures can be attractively and permanently refinished without replacing the wood trim exteriorly -or interiorly thereof and affording protection therefor against the elements, destructive insects, and other deteriorating factors.

An object of the invention is that of providing a pre fabricated sheet metal or plastic trim which is readily adaptable for application to any kind of wood framing or facings on old or new construction to prolong the life thereof or to enhance its appearance by a natural metal finish, such as aluminum, or enamel of different hues, depending upon the individual requirement.

A still further object of the invention is that of providing a metal trim for cornices or around the eaves for an existing wood structure and designed to cover or enclose the wooden trim to renew and modernize its appearance and afford a permanent finish therefor which would obviate the necessity for painting or renewing such trim.

Broadly, the invention contemplates the provision of a metallic armor or shield for architectural finish or trim by which existing materials can be made both permanent and attractive with a minimum of effort and expense.

While the foregoing objects are paramount, other and lesser objects will become manifest as the description proceeds, taken in connection with the appended drawings:

Figure 1 is an isometric illustration of a window frame on which the invention is applied.

vFigure 2 is a vertical sectional view, on lines 22 of Figure 1, showing the application of the casing, header and sill shields applied to a window frame.

Figure 3 is an isometric illustration of an embodiment of the invention for application to a window or door header or facing, having closed ends.

Figure 4 is another isometric view of a metal shell for a window or door facing, its ends being open.

Figure 5 illustrates, in an isometric view with portions cut away, a sill cover.

Figure 6 is an isometric view of a cap member for closing the ends of the sill cover shown in Figure 5.

Figure 7 fragmentarily illustrates, in elevation, a corner assembly of a window or door frame trim.

Figure 8 is a sectional view on lines 8-8 of Figure 7 illustrating the association of the horizontal and vertical members.

Figure 9 is a fragmentary elevational view of a mitered corner construction.

Figure 10 is a transverse sectional view of a facing shell taken on lines 1010 of Figure 9.

Figure 11 fragmentarily illustrates, in elevation, another corner structure in which an angular fitting joins the vertical and horizontal members.

Figure 12 is a longitudinal sectional view through the horizontal member and the corner fitting, on lines 12-12 of Figure 11.

Figure 13 is a fragmentary perspective illustration of a section of roof structure showing a cornice trim.

Figure 14 is a fragmentary illustration of a modified form of the eaves trim shown in Figure 13.

Figure 15 illustrates another modification of the eaves trim, shown fragmentarily in perspective.

Figure 16 illustrates, in fragmentary section, an eaves trim for a roof structure.

Figure 17 fragmentarily illustrates, in perspective, the eaves trim shown in Figure 16.

Figure 18 illustrates, in fragmentary section another form of cornice trim on a roof structure, and

Figure 19 fragmentarily illustrates, in perspective the cornice trim shown in Figure 18.

The invention, therefore, comprises a preformed shell 10 having a width conformable to a conventional window or door facing 11 and having right-

angular flanges

12 and 13 along its longitudinal edges of a depth equalling the thickness of the facing 11, as depicted in Figure 4, so as to completely enclose the outer surfaces of the latter in the manner illustrated in Figure 1. The outer flange 13 has an extended right-angular flange 13' thereon which is overlapped by the siding and excludes moisture and air. A similar shell 14 is formed with

flanges

15 and 16 along each longitudinal edge and each end, respectively, as shown in Figure 3, to enclose a header facing 17 in the manner shown in Figures 1 and 2.

The

shell members

10 and 14 are preferably of metal, such, as aluminum, or the like but may obviously be formed on one of several conventionally known plastic materials, and secured in position on the facing boards 11 and 17 by nailing or other suitable means. The application of the shells to the wooden facings will obviate the necessity for painting and protect the same from the elements.

The vertical shells 10 can be joined to the horizontal header shells 14 in any desired manner, such as by abutments, as shown in Figure 1, or by mitering the joint, as in Figure 9, or in the overlapping arrangement illustrated in Figures 7 and 8. In the latter assembly the upper end of the shell 10 has the

flanges

15 and 16 cut back to leave only a tab or flat end portion 13 which extends beneath the horizontal header shell 14 through an open portion defined at the end of the latter by cutting away a section'of the lower flange 15 thereof. The tab 18 is shown in dotted lines in Figure 7.

A more substantial joint structure for the vertical shells 10 and the horizontal shells 14 is illustrated in Figures 1-1 and 12 in which is provided an angular fitting 1 having inner and

outer flanges

20 and 21 conforming in dimension to those of the

members

10 and 14, and spaced so that the right-

angular legs

22 and 23 of the fitting 19 will embrace the ends of the

shells

10 and 14 in the manner illustrated in dotted lines in Figure 11, and in cross-section in Figure 12. If desirable, the ends of the

members

10 and 14 can be recessed the thickness of these members so that relatively even surfaces will be presented.

A sill casing 24 is provided by which the window sill 25 is enclosed and this member comprises a box portion 26 which embraces the overhanging portion 27 of the sill 25 and has a depending flange 28 formed along its lower inner edge and is engaged by a mold strip or apron 29 nailed along the wall 30 beneath the sill 25, as illustrated in Figure 2. Formed with the top of the box portion 26 is an apron 31 which is adapted to extend inwardly over the body of the sill 25 and beneath the window stool 32, the opposing ends 33 and 34 of the apron 3.1 abutting the jambs 35 on each side of the window frame. Each of the extended end members of the box portion 26 has an upturned flange 26 on its inner edge which is overlapped by the lower ends of the casing shell members and serve to exclude moisure from the wood.

To completely enclose the sill 25 a pair of caps 36 are provided to be placed over the extending ends of the sill 25 and enter the open ends of the box portion 26. One of the caps 36 is illustrated in Figure 6 and in operative relation to the sill casing 24 which latter can be preformed to fit a standard window sill or fitted by a mechanic to meet any special requirements as to dimension and form.

In Figures 13 through 19 are illustrated cornice and eaves trim designed to enclose and provide an easily installed and effective finish for the edges of roof structures which generally, in cornice construction, are finished with a wood drip plate 37 which is nailed to the outer ends of the rafters 38, in the manner shown in Figure 13. In this type of finish an angular strip of metal 39 is arranged along the plate 37 to cover the same and has an angular portion 40 which is turned inwardly and lies along the outer edge of the roof decking 41 to which the shingles 42 are attached, the outer course of which overlies the angular portion 40, as shown in Figures 13 and 18. A right-angular portion 43 of the strip 39 extends inwardly below the rafters 38 to the wall 44 to which it is attached by a depending flange 45 by placing thereover a wood plate 46. Thus the drip plate 37 and the outer ends of the rafters 38 are enclosed within an attractive finish and protected against the deteriorating effects of the elements, nesting birds, and the like.

As illustrated in Figures 14 and 15, the structure just described and shown operatively installed in Figure 13 can be modified and made sufficiently flexible in its application to suit different requirements as to the extent of eave overhang. In these structures a channel strip 47 is provided which has upper and

lower flanges

48 and 49 formed therewith, the upper flange 48 being inclined upwardly to conform to the slope of the roof structure to which it is applied. The bottom or lower flange 49 is right-angular and is designed to support the. outer edge of a plate 50 having a flange 51 depending from its inner edge to be secured along the wall 44 by the wood plate 46, the overlap engaged by the flange 49 being great enough to permit of expansion to accommodate cornices of diflerent dimensions.

The device shown in Figure is similar to that depicted in Figure 14 but includes a plain strip 52 which is adapted to extend between the lower flange 49 of the member 47 and the plate 50 attached to the wall 44. This arrangement can be provided to enclose eave structures having a relatively wide overhang.

In Figures 18 and 19 are shown an eaves trim for cornices having a minimum overhang, or when the rafters 38 are cut so as not to extend beyond the plate 53. The flanged strip 54 is formed similarly to the member 39, having an upper flange 55 to overlap the lower edge of the roof decking 41, and having the same inclination, and a lower right-angular portion 56 which is of much lesser width than the right-angular portion 43 of the member 39, or of a dimension sufficient only to span the thickness of the drip plate 57 which, in this instance, has its inner surface flush with the wall 44. A depending flange 58 provides means for securement by a plate 59 nailed to the wall 44.

A gable trim is provided and is shown in Figures 16 and 17, and comprises a body portion 60 having an angular portion 61 formed along its upper edge. The angular portion 61 includes a flange 62 which is adapted to overlie the edge of the roof decking 41 and extend beneath the shingles 42, in the manner shown in Figure 16, the angular portion 61 enclosing the wood mold strip 63 beneath the extended decking 41 at the gable end while the main body portion 60 covers the exposed outer surface of the rafter 64. An inwardly extending flange 65 formed along the lower edge of the body portion 60, embraces the under edge of the rafter 64.

The concept of the invention herein expressed, and illustrated in its variety of applications, is obviously capable of certain modifications as to design and structural details, by persons skilled in the art, without departing from the spirit and intent of thereof or the scope of the appended claim.

What is claimed is:

In a protective trim for window and door facings of wood, in combination with a pair of jamb and header facings and a window sill, a shell formed of a metal strip having its opposing longitudinal edges bent at right-angles to its plane surfaces, the said flanges and said plane surfaces having dirnensions equal to that of the thickness and the breadth of said facings and adapted to conformably enclose the latter, angular fittings joining lengths of said shell in right-angular arrangement about the corners of a window or door frame, a sill casing having an apron adapted to extend inwardly over said sill and having a box portion embracing the forward edge of said sill casing and projecting beyond the ends of said apron, and detachable caps conformably closing the ends of said box portion upon the ends of said sill.
