Claims. 01. 1609i)) This invention relates to a window construction and more particularly to the construction of a primary window for buildings.
An object of this invention is to provide a primary window in which the frame and the sash are constructed of metal and incorporated in the building in a wall of conventional construction.
A further object of this invention is to provide such a primary window in which the metallic frame and sash are so mounted in the building wall that objectionable features of conventional all metal windows are alleviated.

Fig. 12 is a sectional side view of said modified form of installation with the window frame also shown in elevation.
Fig. 13 is an inside view thereof showing the manner in which my improved window frame is locked in closed position.
As illustrated in the drawings, my improved window construction includes a primary window frame 5 which is preferably of extruded channel iron construction and includes side bars 6 6, a top bar 7 and a bottom bar 8.
The said top and side bars are cross-sectionally formed to provide an outer channel 9 therein and parallel side flanges 1010 extending outwardly. The said bars have front and rear portions 11 and 12, respectively, and
2 an intermediate wall 13 which divides the said bars into a plurality of slots which include an outer channel 14 and an inner channel 15. The inner free end portions of the said walls 11, 12 and13 are thickened to provide bearing surfaces for the sash and screens which will be hereinafter fully described.
The said side bars and upper and lower bars of the frame are preferably secured together by means of angle bars 16 which are secured to the said channel bars by suitable means such as screws 17 to simply secure the said sections together.
Within the said frame, there is preferably mounted an upper sash 18 and a lower sash 19 which are slidable in the channels 14 and 15, respectively. The said upper and lower sashes are also mainly constructed of extruded cross-sectionally U-shaped metallic bars 20 which are secured together by inside angle bars 20 a and have side walls forming channels opening inwardly in said frame; the said side walls being provided on their inner faces with elongated ribs 21 providing locating stops for the glass which is mounted in the said upper and lower sashes.
As shown in the drawings, the said glass is preferably of the insulating type which includes spaced panes of glass 2222 having between them a third sheet 23,
preferably of transparent plastic, and separated by spacing border strips 24 which divide the space into two deadair compartments and thereby greatly increasing the insulating efiiciency of the said glass.
The lower channel bar 25 of the upper sash as an upwardly extending hook portion 26 which engages with a downwardly extending hook portion 27in the upper bar 28 of the lower sash and provides a closure for the space between the upper and lower sashes.
The said sashes 18 and 19 counter-balance each other by means of chains 29 which extend over pulleys 30 that are rotatably mounted in the upper portions of the side channel bars 6-6. The intermediate wall 13 of said side channel bars and of the top channel bar 7 being cut away at the upper corners of the frame, as at 31 and 32, to provide spaces within said frame for the pulleys 30; the said pulleys being mounted to the side channel bars by a shouldered stud 33 which extends through the wall 6 of the channel bar and'the angle plates 16. The said chains are preferably secured to the sashes by means of suitable hooks 34 which are connected to brackets 35 that are secured to the opposite sides of each sash and extend outwardly therefrom to align the chains with their respective pulleys.
The said sashes 18 and 19 are each laterally retained in position relatively to the side channel bars by means of a spring 36 which is secured to the sash by-a screw 38 and engages the outer walls of the channel bars and forces the sash towards the opposite side of the window. The upper sash is laterally guided with respect to the side channel bars, by means of a stop 39 at the lower portion of the sash, which engages the inner surface of the respective rear wall 12, and a stop 40 which is mounted at the upper portion and engages the said intermediate wall and also provides an abutment that engages the intermediate wall of the upper channel bar and limits the upward movement of the upper sash.
The lower sash is guided laterally in said channels by means of an abutment 41, that is formed at the end of the hook portion 27, and by means of a flange 42 which extends inwardly from the lower sash and has an abutment 42-a at its end engaging the inner surface of the wall 12 of the respective side channel bar.v
The hook portions 26 and 27 are notched at..43 and 44 to allow a limited amount of lateral movement of their respective sash and permit the opposite edge of the m3) sash to clear the inner surfaces of the side channels when it is desired to remove the sash from the window frame by forcing the sash sideways against the tension of their respective springs 36, until the said opposite edge has cleared the channel bar, and then pulling the said opposite side of the sash inwardly and disengaging the other side from its respective side channel bar.
'It will be noted that each of the notches 43 and 44 provides a projecting lip portion which extends inwardly from the respective sash and engages the inner surface of the intermediate wall of the opposite side channel bar to provide a stop for the sash.
As shown in Fig. 4, the thickened portion of the said intermediate wall is provided with a notch 45 adjacent the top of the sash to receive the lip of the lower sash when it is raised to the top of the frame and thereby permit lateral movement of the upper sash so that it may be removed from the frame. A similar notch 46 is also provided at the lower end of the frame to receive the lip of the upper sash and permit removal of said sash when it is moved to a position adjacent the bottom of the frame.
The lower sash has a plate 47 which is detachably secured to the flange 42 so that it may be detached therefrom to allow lateral movement of the sash when it is to be removed from the frame.
The flange 42 is particularly intended to provide a handle grip for raising and lowering the lower sash, which in turn causes raising and lowering of the upper sash in reverse order through the counter-balancing chains and pulleys 29 and 30.
My improved window is also provided with upper and lower screens 48 and 49, respectively, each of which includes a frame that is constructed of extruded channel bars having a groove b with an inwardly angled wall 51 that is of a lesser width than the thickness of the channel bar to receive a screen cloth 52 within the confines of said thickness; the said cloth being secured to its respective frame by extending the free edge portions thereof into the said grooves and securing said portions with a suitable anchoring strip 53, such as a strip of flexible rubber which may be forced into said groove.
The screen 48 is mounted at the inner side of the window, above the lower sash 19, and is slidable in the same channels of the frame as the lower sash. The lower screen 49 is mounted at the outer side of the window frame, below the upper sash, and is slidably mounted in the same channels of the frame as the said upper sash.
The said lower screen has, at the upper edge of its frame, a flexible strip 54 of rubber, or other suitable material, which is secured to said edge and extends inwardly therefrom and engages the surface of the outer pane of the lower sash to close the space between the outer screen and the said sash which is taken up by the thickness of the intermediate wall portion 13 of the frame channel bars.
The said lower screen is guided laterally in its respective channels by means of a stop 55, at one side, and at its opposite side by a spring 56 which engages the bottom of the channel and forces the screen laterally into position.
The upper screen has a spring 55-a which is secured to the outer side of its frame and engages the inner surface of the intermediate wall 13 of the respective side channel bar so that it forces the screen towards the opposite side of the window frame. The said upper screen is guided by stops, preferably inv the from of studs 56-a, that are located at the opposite side of the screen frame and engage the inner surface of the outer wall 11 of the respective side channel bar.
It will be noted that the said upper screen is provided with spring pressed balls 57 which engage with the inner surfaces of the said inner wall portions and thereby support the screen in its normal position at the top of the window frame, as shown in Fig. 4.
My present invention is particularly directed to the mounting of said window in the wall structure of a conventional building. As shown in Figs. 1 to 3, the said window may be mounted in a frame wall which includes studs 58 between which is mounted the window frame 5 adjacent to the outer side of the said wall. A bordering frame is provided against the said side of the wall and includes a top member 59 and side members 60-60 that are nailed to the said studs. Upon the outer surfaces of said bordering frame, there is mounted a stop frame consisting of an upper member 61 and side members 6262 which overlap the window frame 5 so as to position it within the wall. Stops 63 are provided against the opposite sides and the top of the window frame and are secured to the studs 58 and to a lintel 64 which extend across the top of the window opening and between said studs 58.
At the bottom and inner side of the window opening there is provided a sill 65 which also abuts the frame and provides a stop therefor. An outside sill 66 extends between the studs 58 over a crosspiece 67, and supports the window frame as clearly shown in Fig. 3.
A conventional frame 68 is provided upon the inner side of the wall over the wall finish 69.
As illustrated in Figs. 10 to 13, the window frame 5 may be mounted upon hinges 70 so that the entire frame may be swung inwardly in the window opening to facilitate cleaning of the outside of said window. In this modified construction, side members 71 are mounted directly upon the studs 58 and the said hinges 76 are secured to one of said side members. Separate pieces 72 are mounted upon the inner sides of said side members for trim purposes. At the side of the window opposite the hinges 70, there is provided a suitable bolt 73 which preferably engages with a notch 74 in the respective side member 72 to provide for locking the window frame in closed position. A frame 75 is also provided at the exterior of the wall to provide an abutment for the window and the molding 76 is mounting upon said frame. The inner sill 77 of this window is on a plane with the outer sill member 78 and below the frame 5 to permit opening of said frame.
The construction shown in Figs. 1 to 3 may be used particularly in cases where it is desired to remove an old window frame from a building and replace it with my improved window. In such cases, the old frame is removed up to the studs 58 and my improved frame is then set into the opening and trimmed as shown in Figs. 1 to 3.
The construction shown in Figs. 10 to 13 may also be used in old buildings to replace old wooden windows as well as in new buildings.
A particular advantage is gained by mounting my improved metallic window frame in a wooden structure, such as shown in the drawings, for the reason that the metal frame of the window, which is of a high thermal conductivity, is shielded by the wooden frame and trim of the wall structure which is of a relatively low thermal conductivity and thereby eliminates the formation of the objectionable frost and fog, upon the inside surfaces of the metallic frame, which commonly occurs in installations where the metallic window frame is exposed to low outside temperatures while the inside of said frame is exposed to the warmer temperatures.
It will be understood from the above description that, in the use of my improved window, the screens 48 and 49 will remain in the position shown in Fig. 4. When the lower sash 19 is raised, the upper sash 18 will automatically be lowered and both sashes will engage their respective screens, thereby leaving the window open above and below the sashes and providing for circulation of air through the window.
When it is desired to remove the upper sash 18, it is merely moved to the bottom of the frame, until the rib 43 is in register with the notch 46, and the said sash is then moved sideways against the tension of the spring 36 to disengage the opposite side of the window from its respective channel in the side channel bar 6 and thereby allow the sash to be removed from the frame.
The lower sash 19 may be removed from the frame in the same manner, by raising said sash to the top of the frame, until the rib 43 is in register with the notch 45, and then moving the said sash sideways and disengaging its opposite side from the respective channel in the window frame.
I claim:
1. A window construction including a frame constructed of a plurality of channel bars forming the side and top of the said frame, each of said channel bars having spaced parallel channels therein opening inwardly of said frame, a separate bar forming the bottom of the frame and having an upstanding flange at the inner side thereof, a sash slidable in each pair of opposed channels in said frame, a pulley rotatably mounted within and adjacent the top of the frame, a chain-like member extended over the said pulley and connected to each of the sashes to thereby support them in different positions and counter-balance one sash with the other, interlocking means between said sashes for closing space between them, the lower sash being engageable with the upstanding flange of the lower bar and having a flange portion extending inwardly above said upstanding flange to provide a hand grip for the sash, a stop member detachably secured to the said flange portion for engaging the surfaces of the respective channel bar to prevent lateral movement of the lower sash in one direction, a projection at the upper portion of the lower sash cooperating with the said flange to prevent sideways movement of the sash in its respective channel bar, the said channel bar having notches adjacent the top and bottom of the frame to register with and receive the said projections and the said stop member being detachable to thereby permit sideways movement of the sash in its respective channels, and spring means between the side of each sash opposite the stop means thereon and the bottom of its respective channel for urging the stop means into engagement with the channel bar and thereby slidably retaining the sash in the window frame.
2. A window construction including a metallic frame constructed of a plurality of channel bars having spaced inner and outer parallel channels therein, a sash slidable in each of said channels, one of said sashes being normally disposed adjacent the upper portion and the other sash adjacent the lower portion of said frame, pulleys rotatably mounted in the upper portion of the frame, means extending over said pulleys and secured to said sashes for counterbalancing the sashes and supporting'them in different positions within the frame, an upper screen slidably mounted in said inner channels above the lower sash therein and a lower screen fitting in the outer channel below the upper sash therein, the said screens being spaced equally from their respective sashes to thereby cause closing of the spaces between the screens and said sashes equally upon the movement of said sashes towards opened position.
3. A window construction as set forth in claim 2 wherein the lower screen is provided with a projection extending from the upper portion thereof and engaging the surface of the lower sash to thereby close the space between said lower sash and screen.
4. A window construction as set forth in claim 2 wherein the upper screen is provided with spring pressed means engageable with the inner surfaces of the respective channels in which said screen is mounted to thereby support said screen in position within the frame.
5. A window construction as set forth in claim 2 wherein the upper screen is provided with a spring member mounted upon the outer surface thereof and located adjacent one side of the screen and slidably engageable with the inner surfaces of the respective channel bar between the parallel channels at one side of the frame to thereby urge said upper screen towards the opposite side of the frame, and stop means at the opposite side of the screen engageable with the opposed surface of the respective channel bar to slidably locate the screen in said channels.
