the structure of which. the window or door is merely a part.
Speaking generally, only a. triangular frame, pin-connected at the angles, is structurally rigid and cannot be distorted except by bending or breaking one of the sides of the triangle, whereas a. pin-connected unit of four sidesor elements of fixed length, may be built rectangular but may readily be distorted to form any parallelogram without bending or breaking one of the sides.
Window sashes, and window and. door frames are. of course, not pin connected at the corners but they are generally rectangular in outline and cannot be resolved into triangular units because of the impracticability of inserting a diagonal member extending between opposite corners. The sides of such frames and sashes usually meet in a miter, and the strength at the miter alone provides the only resistance to distortion. Where the stiles and rails of a 'door frame, for, example, are of substantial size, the problem of corner bracing presents no great difficulty, but when the stiles and rails are of extremely light material, such as sections formed from thin metal sheets or strips, merely welding such sect-ions along thevmiters does not form a satisfactory structure. Neither is it satisfactory to provide at the corners either an angle brace in which the two sides of the brace lie in the same plane or in which the two sides lie in rectangularly disposed planes. To attain the best results and assure structural stability and resistance to distortion in all directions the corners of 50 the frame should bereinforced by angular 1.930. Serial No. 463,418.
elements of such shape or configuration that theytend substantially to resist distortion by tension or compression rather than by. mere bending.
We accomplish this desired end. by the novel elements and the combinations and arrangements thereof described below and il-, lustrated in the accompanying drawings in which i Fig. 1 is a fragmentary perspective View showing one corner of a frame embodying. our invention and the strengthening mem ber applied thereto;
Fig. 2 is a cross section taken through the frame and the bracket. member in the plane 2-2 of Fig. 1; a
Fig. 3 is a perspective View of the bracket or strengthening member;
Fig 4 is a modified form of the bracket member p I I Fig. 5 is a still further modification of a bracket member;
Fig. 6 diagrammatically illustrates a complete frame, the sides of which meet in a miter, and without the bracket member of our invention applied thereto; and I Fig. 7 is a diagrammatic view illustrating the manner in which the frame is distorted when a force is applied to the same in a direction tending to collapse the frame.
Like reference characters indicate partsthroughout the drawings.
Referring now to the drawings in which we have illustrated certain preferred embodiments of our invention, 10 is'a metallic frame formed of comparatively thin, rolled, sheet metal. In Fig. 2 we have illustrated one form of a sheet metal frame, the edges of which are folded back as at 11 and 12 and spaced from the main body of the frame. In the embodiment of our invention illustrated, the frame is intended as a sash for a window and is formed with. an angle portion, the sides of which are indicated at 112 and121; the window pane being received against the side/.112.
The sides of the frame meet in a miter as at 13, the two meeting edges of the frame preferably being welded together. The bracket or strengthening member is indicated like secured to the frame, the bracket member forms in effect a beam or gusset having portions which resist by tension and compression the distortion or collapsing of the frame. The flange, 16, is secured to the frame by welding, as at 18. Preferably, also, the plate, 15, is welded to the frame as at 20.
Preferably, the edges of the bracket memher are also provided with additional flanges at their extreme ends as at 161 and 171 which are received in the spaces between folds, 11-
and 12, respectively, and the main body of the frame, the flange, 1'71, preferably being welded to the frame as at 19.
' In the embodiment of our invention illustrated in Fig. 4 the bracket member. 1411, comprises an angularplate, 151, and two plain outwardly extending marginal flanges, 163. Obviously the strengthening bracket illustrated in Fig. 4 could be applied to a frame having a different contour in cross section from that illustrated in 2.
In Fig. 5 we have illustrated a still further modification of our invention in which the angular plate, 152, is provided with an outwardly extending flange, 7 162, and an inwardly extending flange, 172. The strengthening bracket illustrated in Fig. 5 could also be applied to a different form of a frame from that illustrated in Fig. 1'.
A frame, the sides of which meet in a miter as illustrated in Fig. 6, is comparatively weak when formed of relatively thin sheet metal in connection with which our invention isparticularly useful and particularly when the edges of the frame meeting in the miter are welded together When, for example, forces are applied to the two sides, 101 and 102, of the frame as illustrated in Fig. 6, these forces tend to collapse the frame, causing the miters,
the flanges being placed under tension in one case and under compression in he second. We
are thereby enabled to form the frame of comparatively thin sheet metal and at the same time-make the frame sufficiently strong to resist any forces to which it is ordinarily subjected.
In assembling the frame and bracket, one side of the frame is slid over one side of the bracket, and the other side of the frame is then slid over the other side ofthe bracket and the two edges of the frame are then tion in its preferred embodiment it is to be understood that the words which we have used are words of description ratherthan of limitation, and that changes within the purview of the appended claims maybe made without departing from. the true 'scope'and spirit of our invention in its broader aspects- What we claim is 1'. In combination, a frame formed of sheet metal the sides of which are bent in cross section and meet at an angle to form a miter,
and an angular metallic member formed of sheet metal, the two sides of which extend generally parallel to the sides of said frame, said metallic member comprising a plate and two marginal flanges extending along both portions of said member and in opposite direction from said plate, the planes of said I flanges extending at an angle to the plane of said miter, said flanges being secured to the sides of said frame.
2. In combination, a frame formed of sheet metal the sides of which are bent in cross section and meet at an angle to form a miter, the margins of said frame being folded back and forming spaces between the folds and the body portion of the frame, and an angular v metallic member the two sides of which extend generally parallel to the sides of said frame, said metallic member comprising a plate and a marginal flange extending along both portions of said member, the plane of said flanges extending at an angle to the plane of said miter, and the edges of said flanges being provided with portions recessed within the spaces between the respective folds at the edges of the frame and the body portion thereof, said flanges being secured to the sides of said frame.
3. In combination, a frame formed of sheet metal the sides of which are bent in cross section and meet at an angle to form a miter,
and an angular metallic member formed of sheet metal the two sides of which extend generally parallel to the sides of said frame, said metallic member comprising a plate and two marginal flanges extending along both portions of said member and in opposite directions from said plate, the planes of said flanges extending at right angles to the plane of said miter, said flanges being secured to the sides of said frame EDWARD J.
