To all whom it may concern: I
Be it known that I, "WILLIAH D. FOR- srTi-I, a citizen of the UnitedlState's, residing at Youngstown, in the county of Mahoning and State of Ohio, have invented. a new and useful Metal lVindowJ rame, of which the following is a specification. f
Myinvention relates to a new andlilseful form of metal window frames, adapted to be used in place of wood or other material here:
tofore used in making sashes for windows.
' to form the stiles or barsof the frame.
'My' invention consists in an improved metal window frame of easy and cheap manufacture, it is strong, flexible and adaptable in use in making and operating windows.
My improved metal window frame is illustrated in the accompanying drawings in which Figure 1 is a. perspective view of the top molding of my window frame. Fig. 2 is another, view of the same top molding notched for the reception of the stiles or bars of a window-frame. Figs. 3 and 4 are" perspective views of the metal sections used Fig." 5 at a is a vertical cross section of 4 at see i tion line a a. Fig. 5 at Z) is a joint formed i by 8 and 4 with 4 shown in elevation and 3 i in cross section at a line flush with the web I of 4. Fig. 5 at 0 shows across section of 3 at sectionline c c. Fig. 6 is a joint formed by 3 and 4 with 3 in elevation and 4 in crossf secti'on at a line flush with theweb of 3. Fig. 5 7 is a perspective view of the joint of the' frame formed by the bars or stiles 3 and 4. Fig. 8 is a cross section of molding 2 mounted upon stile 4. Fig. 9 is a cross section of I molding 2 and stile 4, with the slips G, C, holding panes of glass in place; dotted lines showing position of putty. Fig. 10 shows:
perspective view of molding 1- with a U section used for the stile or bar and substituted for the T section shown in the preceding figures. Fig. 11 shows the clip 0 in elevation and end view. Fig' 12 shows a. joint'in my improved window frame with T section used for the bars or stiles thereof and top molding attached thereto, part of said noldingbeing uotchedand continuous and the other part of said molding being parted at said continuous molding.
:top molding. thus assembledwith the notched top mold- ,The to molding of my improved frame andthe 'sction form tifthe' stiles or bars thereof are preferably formed by rolling metal to the cross section of said molding and the said T section of said stiles orbars shown in Figs. 1, 2. 3, and 4. Aftersaid molding has been rolled of a suitable metal of suitable dimensions, it is-notched as at 2, Fig. 2, so that it may be passed over the flange of 3 when the same is placed on 4 to form a joint as in Fig. 7 The bar or stile shown in Fig. 3 is preferably rolled in T section of suitable metal and dimensions and is notched at 3 as shown, in Fig. 3, so that it may he joined with baror stile 4. Bar or stile 4 shown in Fig. 4 is made of suitable metal by rolling in the T sectionand is notched at 4 4, Fig. 4, so as. to form with 3 the oint or cross shown in Fig. 7. r
hen the T section stiles or bars 3 and 4' are notched and assembled by, placing them so that the notches therein coincide so as to form. the structure shown in Fig. 7, with the top surface. of their flanges flushed with one another and with the bottom parts ofsaid flanges in substantially the same plane'g thc top molding shown in Fig. 2 is placed longitudinally with stile 4 so as the flange of 3 is inserted in the notches 2 2 of said The bars or stiles 3 and 4 as ing 2 are placed in a press and the ends 2 2 of molding 2 are pressed around the flanges of 4 as shown in Figs. 9 and 12. After stiles or bars 3 and 4 have been as sembled in any desired number and the notched molding 2 is placed thereon and the ends thereof 2 2 are pressed around the flanges of said stiles or bars 4, lengths of molding 1 are cut of siiflicient lengthso that B of molding 2 in one member of the frame to the next adjacent molding 2 over the next parallel stile of the' frame. Said short lengths of molding 1, Fig. 12, are fitted and formed at both ends so as to conform to the lines and curves of molding 2. Said short lengths of molding 1 are then placed over the flanges of stile or bar 3 and the ends 1 of said molding 1 are pressed around the flanges of stile 3. When the T section stiles or bars 3 and 4am connected together at their notched portions and molding 2 is placed over the flanges'of stile or bar 4 and the ends of molding 2. pressed around the flanges of said bars and the short lengths of the bead 1 thereof will extend from bead .3, the construction shown in Fig; 12 results.
Clip C is. made of sheet metal and is pressed and cut in the shape shown in Fig. 11 when it is used in connection with my frame before the ends of moldings 1 and 2 are pressed around the flanges of 4 and 3 respectively, said 'clip C is placed at intervals under said flanges and next to the web of said stiles or bars3 and 4, and when the ends of moldings 1 and 2 are pressed around the' flanges of said bars or stiles, said ends are made to include the ends of said clip so as to form the construction shown in Fig. 9; putty may then be placed under the flanges of the stiles 3 and 4' so as to occupy the space shown in dotted lines, Fig. 9.
Fig. 10 shows a U shaped section substituted for the T. section of the other figures the clip C being substituted by the tongue T punched from the U shaped stile.
