METAL WINDOW CONSTRUCTION Original Filed March 8, 1957 .3 Sheets-Sheet 3 INVENTOR qrthuzr.ZL]KEehZ United States This application relates to window structure and particularly to a trim casing forming part of the window frame, and is a division of application Serial No. 644,851, filed March 8, 1957, now Patent No. 2,916,112, issued December 8, 1959.
The window frame structure includes a tubular trim casing that covers the interior of the wall opening inwardly of the frame and that is provided with a trim portion at right angles to the tubular portion for engagement with the interior of the building wall around the window opening. The tubular rectangular body of the trim casing is adapted to receive the inner edge portion of the window frame and is clamped to the inner edge of the frame by suitable means- The trim casing is formed of four members of identical cross section provided with end portions that are adapted to interlock to permanently connect the four members to form the rectangular tubular casing, with the trim flanges coplanar and provided with mitered interfitting portions at the corners.

FIG. 15 shows the sections just prior to the completion of the interlocking operation.
Referring to the accompanying drawings, the window of the present invention has a frame formed by jambs A,
atent Cl a head B and a sill C. The jambs A are of identical ice of the jabs A, is also an extruded structural shape and the same is true of the sill C which connects the lower ends of the jambs A.
In order to center the window frame in the wall opening 56 a series of springs 59 are mounted exteriorly of the jambs, head and sill for engagement with the sides, top and bottom of the wall opening 56. The springs 59 are in the form of curved sheet metal plates having curved outer end portions 60. The springs 59 are of short length and several of these springs may be spaced apart along the length of each jamb and along the length of the head and the sill. The inner end portions 62 of the springs 59 are curved on a longer radius than the outer end portions 60 and the inner free ends of the springs 59 are bent at 63 to provide inclined portions that project outwardly from the exterior of the frame when the springs are mounted on the frame.
The portions 62 of the springs 59 have Wedging engagement with the interior of the wall opening 56 as the frame is pushed into the opening and, since the outer end portions of the springs are backed by portions of the jambs A, head B and sill C, the engagement of the springs with the interior of the wall opening compresses the springs and forces the inner ends thereof inwardly toward the exterior of the window frame. The springs 59 serve to center the window frame in the wall opening prior to the attachment of the jambs A, head B and sill C to the building wall.
inwardly of the Window frame there is provided an interior trim casing 64 that has a rectangular tubular portion formed by four walls 65 that covers the interior of the wall opening inwardly of the window frame, the casing having trim portions 66 extending outwardly from the walls 65 at right angles thereto and overlying the interior of the building wall around the window opening. The trim portions 66 have reversely bent edge portions 67 provided with inturned flanges 68 that engage with the building wall. The rectangular tubular body within the wall opening composed of the four Walls 65 is of a size to receive the inner edge of the window frame. The casing 64 can be pushed into the window opening from the interior and the outer edge of the walls 65 Wlll engage with the inclined edge portions 63 of the springs 59 to force the free ends of the springs 59 outwardly sufliciently to permit the walls 65 to enter between the springs 59 and the exterior faces of the jambs, head and sill, the springs 59 serving to clamp the inner ends of the walls 65 against the edge faces of the window frame members.
The trim casing 64, which may be formed of sheet steel and provided with a paint or enamel coating, has its sections formed so that they can be quickly and easily assembled and permanently joined together without the use of separate attached means such as screws, bolts or clips. The trim casing 64 is composedof four sections, each including one of the flat body portions 65 that forms a Wall of the tubular portion of the casing. Each section is provided at one end with a flange 194 that extends from the free edge of the body portion 65 to a point substantially midway between said free edge and thetrim portion 66 of the section and that project from the interior face of the portion 65 at right angles thereto. The opposite end of each section is provided with a flange 195 projecting in the same direction as the flange 194 and extending from near the trim portion 66 to a point substantially midway between the trim portion '66 and the free edge of the body portion 65. The end of the flange 195 adjacent the trim portion 66 may have its corner cut away to provide a'beveled edge 196 and a short end shoulder 197. The ends of the trim portions of each section extend past the side edges of the body portion 65 and overlap when the sections are joined.together to provide a corner joint. At the end of the Section provided with the flange 194, the entire trim por- 7 tion 66 projects past the end of the portion 65 to provide an attaching projection 198 of a length but slightly less than the width of the portion 66. The opposite end of each section is provided witha'mitered projecting portion 199 having its outer end edgedisposed at an angle 45 to the portion 66 of the section and extending to the inner end of the flange 195.
The face of the projection 198 has a triangular depression 200 which receives the mitered projecting portion 1990f the trim 66 to provide a mitered joint in which the external faces of the trim portions 66 are flush. The outer end ofeach projection 198 is provided with a toothediflanget 2'01 projecting toward the flange 63 that engagesthe inner side of the portion 67 of the section with which the projection 198 engages; The sections may be permanently locked together by bendingza portion'of each flange 68. over the underlying toothed flange 291 ineach corner of the casing. t
In assembling the casing the sections are joined at three of the corners simply by inserting the flange 195 into the space between the flange 194 and the inner face of the integral trim portion 65 of the adjoining sections, a
with the sections disposed at an angle as shown in FIG. 12, then swinging the sections to the' position shown in dotted lines in FIG. 12. The fourth joint is formed by springing the free ends of the sections to be. connected at the fourth corner laterally one with respect to the other, to permit the free edge of one, section 65 to be inserted beneath the flange 1940f; the other section and the flange 195 of the first-mentioned section to be engaged with the exterior face of said other section as shown in FIG. 13. The flexibility of the body portions 65 of the sections permits the section having its free edge beneath the flange 1940f the other section to be moved. laterallyrwith respect to the other section to advance the flange 195 toward the flange 194 with the edge of the flange 195 sliding o'n'the edge of the body portion 95 of the other section adjacent the projecting end of the trim portion 66 of said other section. As the flange 195 of one section moves toward the flange 194 of the other, the section so moved is bowed between the portion engaging the inner side of the flange 194 and the portion engaging'the edge of the body portion 65 of the other section, causing increased pressure on the edgeof the flange 195 due to the resiliency of' the sheet metall In order to relieve this pressure as the outer end of the flange: 195 approaches the inner end of the-flange 194, the bevel 196 is provided. During this movement the mitered end 199 moves toward the depression 280' in the projecting portion 198 formed to receiveit. In the final portion of this movement, the flange 195 snaps into place engaging the mitered end 199' in the depression 2% and the end shoulder 197 of the flange 195 with the inner face of the trim portion 66 of the other section. With the'fianges so positioned, the sections are firmly interlocked, but, in order to provide a permanent connection which will prevent springing" apart of the overlapping projecting portions 198 and 192, an end portion of each flange 68 is preferably bent over into engagement with the toothed flange 201.
It is to be understood that in accordance with the provisions of the patent statutes,variations and modifications of the specific devices herein shown and described may be made without departing from the spirit of the invention.
