J. L. M GLOTHLEN METAL WINDOW CONSTRUCTION Filed May 9. 1929 2 Sheets-Sheet 2 Patented Feb. 3, 1931 mettle EQE JOHN L. MCGLOTHLEN, OF HUNTINGTON, WEST VIRGINIA, AEGIS-NOR TO FULTON TOOL WORKS, F HUNTINGTON, "WEST VIRGINIA, A CURPORATION OF WEST VIR- GINIA Application filed May 9, 1929.

The invention relates to metal windows to be used. in connection with dwelling houses, business buildings and structures of any sort where ingress of light and air is desired.

The construction of ordinary metal windows in use at the present time, necessitates many exposed screw heads and a considerable number of these, being on the outside of the windows, are exposed to the weather, caus- 1 ing them to become corroded. V

In addition, the construction in ordinary usage produces a window lacking in rigidity, tending in time to produce a partial separation of the various members.

Further, in the installation'of the ordinary metal window, it is necessary to use a plastic caulking material between the wall and the window frame in order to provide a weathertight structure.

The objects of the present improvement are to provide for reducing the number of screws necessary to the construction of the metal window; to provide for eliminating practically all screws exposed to the weather; to provide for a more secure joining of the various SQCJlOIlS, and a more rigid construction;

to provide for more effective weather-stripping of the various members; to provide for producing a weather-tight oint between the walls and the window frame without the use 'of caulking material; and to generally improve and simplify the construction of metal windows.

These and ancillary objects are attained in the present improvement by means of the particular design of the various members of the window, together with the method of interjoining and interlocking them.

An embodiment of the invention thus set forth in general terms is illustrated in the accompanying drawings, in which Figure 1 is a fragmentary, plan sectional view of the improved window and frame;

Similar numerals refer to similar parts throughout the drawings.

The improved window, indicated generally at 10 in Figs. 1 and 2, is set in a window opening in the wall 11, of a buileing or other structure. The window includes the head frame indicated generally at 12, sill frame 13, and side frames indicated generally at 14, the construction of each of which will hereinafter be set forth in detail; and upper lower window sashes indicated generally at and 16 respectively.

The upper section 15 includes a window pane 17 cemented by means of a plastic material. within a top sash member 18, stiles 19 and bottom sash member 20, all preferably formed of sheet metal 1n usual and well known manner.

The method of attaching weather-stripping to the top sash is best shown in Fig, 4, It will be seen that when the upper sash is fully raised. as in Fig. 2, the top thereof will enter the coiacavely formed portion 21 of the head frame 12, forming, by means of the weather strip 18 contacting with the portion 21, a weather-tight connection therewith.

The lower window section 16 includes a window pane 22, cemented, by means of a plastic material, within the top sash meeting "ail 23, stiles 19 and bottom sash member 24, all preferably formed of sheet metal in the usual manner.

As best shown in Fig. 5, the lower sash member 20 and sash meeting rail 23 are so constructed that when brought together by the closing of the window, they wedge against each other, any irregularity being compen; sated for by the flexible weather strip 23 attached in, the manner shown, whereby locking the window will only serve to wedge the sash more tightly together.

The bottom sash member 24, of the lower window sash 16, may also be formed otsheet metal, and is arranged to engage the sill 13, preferably formed of sheet metal, as shown in Fig. 2. Said sill may be of any usual and suitable design.

The

stiles

19 and 19, of the upper and

lower window sections

15 and 16, respectively, are n'eferably formed of sheet metal, and slide vertically in slots 19a provlded in the side frames 14. As shown in Fig. 3, the weather strip 19 is attached to the stiles by means of rivets 25, and travels with the sash. The weather strip may have spring tension on both sides of the stile as shown, or on only one side. if desired.

It will be seen that when the sash is placed in the slots 19a, provided in the side frames, the spring tension of the weather strip causes frictional contact wi h the side or sides of the slot in the side frame, producing a weather-tight fit.

The head frame member A, as shown in Figs. 6 and 7, is substantially U-slraped, having

side portions

26 and 26 and the intermediate portion 27, which has formed integral therewith, nibs or pointed flanges 28, the function of which will be hereinafter described.

The portion 26 terminates in an ofiset flange 29. and the portion 2' terminates in the offset flange 29'. Slots 30 are spaced at intervals in the length of the chgnnel portion 31 of the side portion 26, and adjacent to the flange 29.

The head frame member B, shown in Figs. 8 and 9, is substantially U-shaped, having

flanges

32 and 32 and the intermediate portion 33. Tangs 34 are formed at regular intervals along the edge of the flange 32 and at a slight angle therewith. The portion 33 has formed therein the concave portion 21, the function of which has been previously de scribed.

The side frame member C, shown in Figs. 10, 11 and 12, is substantially lJ-shaped, having

side portions

35 and 35 and the intermediate portion 36. The portion 36 has formed integral therewith, nibs or pointed flanges 37, similar to the nibs 28 011 member A, thefunction of which will be hereinafter described.

The side portion'35 terminates in an offset flange 38, and the side 35' terminates in the offset flange 3S. Slots 39 are spaced at intervals in the length of the channel portion 40 of the side 35, and adjacent to the flange 38. Slots 41 are spaced at intervals in the length of a leg 42 of the side 35, and slots 43 are spaced at intervals in the length of the flange 38, and ajacent to the leg 42.

The side frame molding member D, shown in Fig. 13, is of" irregular cross-section as shown in Fig. 14. One side terminates in the narrow flange 45 and the other side terminates in the oppositely disposed flange 46. T angs 46' are formed at intervals along the edge of the flange 46 and at an angle there with. V

The side frame member E, shown in Fig. 15, is of irregular cross-section as shown in F ig. 16, having a lJ-shaped portion 47 termi nating in an edge 47 at one side, and having a wide flange 48 at the other side terminating in the narrow angular flange 48.

Tangs 49 are formed at intervals along the edge of the flange 48 at right angles therewith. i

The side frame molding member F, shown in Fig. 17, is of irregular cross-section, as shown in Fig. 18, having

side portions

50 and 53, and the intermediate portion 53a. The side portion 50 terminates in the inwardly disposed flange 51, at right angles therewith, and the side portionv 53 is preferably straight and terminates in the edge 52. 7

in assembling the head frame 12, the member B is placed in the position shown in dotted lines in Fig. 19, with the tangs 34 in sorted in the slots 30 of the channel portion 31 of the member A. The member B is then swung into the position indicated in full. lines, the flange of B engaging. the flange 29 of A, and the flange 32 of B engaging the flange 29 of A.

By reason of the tangs 34 being angularly disposed with relation to the flange 32' of B and channel 31 of A, the member B will become securely interlocked with member A.

In assen'ibling the side frames 14, the mem: ber D is placed in the position shown in dotted lines in Fig. 20, with the tangs L6 inserted in the slots 39 of the channel portion ll) of member C. The member D is then swung into the position indicated in full lines, the flange of D engaging the flange 38 of C, and the angularly disposed tang -16 interior ring the members C and D at the slots 39.

The member E, which may have an angular member 5 welded thereto, as at 55, is then placed in the position shown in dotted lines in Fig. 21. After inserting the tangs l9 of member E in the slots 43 of member C, member E is swung into the position indicated in full lines, the flange 48 of E engaging flange S8 of C, flange d5 of D engaging the inside of the U-shaped portion 47 as at 56. and the flange of the angular member 5t engaging the member D as at 57. At the same time the edge 47 of the member E'engages the member D, and the members C and E become interlocked at the slots 43.

bcrews 58 may be used to hold the various members in position until the member F is attached. The member F is then placed in the position shown in dotted lines in Fig. 22, and then moved into the position indicated in full lines with the edge 52 of the flange 53 insorted in the slot 4-1 of member C, the flange 5i. engaging member E as at 59, and the flange engaging the flange 48 of member E.

Screws are then inserted through countersunk holes in the intermediate portion 53a of member F, and screwed into member E as at 61, thus rigidly securing member F to member E and finally rigidly interlocking the members G, D, E and F. V

A. strip or channel member 62 may be socured t0 the Ushaped portion 47 of member E, by means of screws 63, in a manner illustrated in Fig. 1, and the legs of this channel form, with members D and F, the slots 19a in which the

stiles

19 and 19 of the

window sections

15 and 16, respectively, slide vertically upward and downward.

hen the window frame is built into the wall 11 as shown in Figs. 1 and 2, the nibs or pointed

flanges

28 and 37 of the head frame and side frames, respectively, are inserted into the wall as shown, bringing the portions 27 of the head frame and 33 of the side frame into contact, throughout their length, with the surface of the wall opening. This provides a substantlally weather-tight joint between the window frame and the wall "ithout the use of a caulking material.

it will be seen that with the above described system of interlocking only a limited number of screws are necessary to construe tion of the improved metal window, and the heads of only a small number of these will 5 be exposed to the weather.
