A 7' TOP/V5 V United States Patent MUNTIN BAR CONSTRUCTION Robert R. Cameron, Denver, Colo.
Original filed January 31, 1949, Serial No. 73,737. Di-
vided and this application February 12, 1952, Serial No. 271,247
1 Claim. (Cl. 189-78) This application is a division of applicants prior application, Serial No. 73,737 filed January 31, 1949, Patent Number 2,591,780, issued April 8, 1952, and the invention relates to a metal sash, and more particularly to metal sash members for forming metal window sash.
The principal object of the invention is to provide a metal sash member from which double glazed metal sash can be quickly and easily formed in any of the varieties and forms for which metal sash are used.
A further object of the invention is to provide a metal sash member with means whereby two spaced-apart panes of glass can be easily applied or removed.
Other objects and advantages reside in the detail construction of the invention, which is designed for simplicity, economy, and efficiency. These will become more apparent from the following description.
In the following detailed description of the invention, reference is had to the accompanying drawing which forms a part hereof. Like numerals refer to like parts in all views of the drawing and throughout the description.
In the drawing:
Figs. 1, 2, and 3 are fragmentary, perspective views, illustrating the three component members from which the double glazed metal sash are formed;
Fig. 4 is a cross-section through a stationary double glazed window, illustrating the use of the improved sash members; and
Fig. 5 is a similar cross-section through a hinged sash panel constructed from the improved sash members.
All of the various conventional types of sash can be formed from various arrangements and combinations of the three simple members illustrated in Figs. 1, 2, and
In Fig. 1 a sash frame bar is illustrated at having a greater width than thickness and provided with an edge flange 11 extending outwardly along one edge thereof to form a rectangular cross-section. A relatively narrow, glass-supporting flange 12 extends along the latter edge from the opposite side of the member 10. A second relatively wide glass flange 13 extends along the latter side of the member 10 at the opposite edge thereof. The first glassflange 12 is inset from one face of the bar to provide an indented, glass-receiving channel 14. The edge of the second glass flange 13 is notched to provide a second glass-receiving channel 15. The second flange 13 projects further from the bar 10 than the first flange 12 so as to offset the two glass channels 14 and 15 from each other.
Screw holes 16 are positioned in spaced-apart relation along and adjacent to both glass channels 14 and 15. The latter holes are for receiving molding screws 17, bv means of which a semi-resilient, longitudinally-bowed glass molding strip 18 may be attached to the bar 10. The molding strip 18 is formed from an elongated strip of resilient metal arched in cross-section, as shown in Fig. 2, and provided with screw openings 19 corresponding in spacing to the screw openings 16.
To form a plain sash, the bar 10 is miter-cut to surround the perimeter of the desired sash and welded or otherwise joined at the corners thereof. An outer glass pane 21 (see Fig. 5) is placed in the outer peripheral glass channel 14. A slightly smaller inner glass pane is placed in the inner glass channel 15. The two panes 20 and 21 are secured in place by attaching strips of the molding strip 18 around the periphery of each pane by means of the screws 17, as illustrated.
It can be readily seen that the above construction forms an enclosed air space between the two glass panes to serve as insulation. It is usually not desirable to have this air space completely closed, due to barometric changes which would create alternate pressure and partial vacuum between the two panes. To relieve this, small air openings 22 are formed through the rnember 10 to communicate with the outside atmosphere. For fixed sash, the peripheral flange 11 is imbedded in the window frame or masonry, indicated at 23, Fig. 4.
For a sash requiring division bars or muntins dividing the glass area into a plurality of panes, a muntin bar 24, as shown in Fig. 3, is used. The bar 23 has a pair of projecting ridges 25 along both of its side faces. The ridges 25 are spaced from, and parallel to, the side edges of the bar so as to form four glass grooves 26. The bar 25 is also provided with screw holes 27 for receiving the molding screws 17. The bars 24 are welded into the frame formed by the bar 10, and the glass panes 20 and 21 rest in the glass grooves 26, where they are secured by means of the molding strip 18, which overlaps both panes, as shown in Fig. 4.
To insert a hinged panel in a sash, the frame bars 10 of the hinged panel are faced to place the edge flanges 11 on the outside, and the frame bars 10 of the fixed sash are faced to place the edge flanges 11 on the inside, so that the two adiacent bars 10 will overlap each other, as shown in Fig. 5, to form two sealing contacts 28. The frame of the hinged panel is hinged to the frame of the fixed sash by means of any of the standard hinges 29.
While the invention has been described as made from metal and as applying more particularly to metal sash, it is to be understood that the advantages are not dependent upon the material from which it is made, as it would be equallly valuable formed from plastic, wood, or other materia s.
While a specific form of the improvement has been described and illustrated herein, it is to be understood that the same may be varied, within the scope of the appended claim, without departing from the spirit of the invention.
Having thus described the invention, what is claimed and desired secured by Letters Patent is:
A muntin bar for separating a pair of adjacent outer glass panes from a pair of adjacent inner glass panes in a double glazed metal window sash, comprising: an elongated fiat bar of uniform thickness throughout its width and having a width equal to the thickness of said sash, the longitudinal edges of said bar adapted to pass between the two panes of each pair of panes to act: as a spacer for the panes of each pair; and two longitudinallv extendin rectangular ridges projecting from each side of said flat bar in parallel, spaced relation to the lonrzitndinal edges of said bar and adapted to separate the pair of outer glass panes from the pair of inner glass panes. the longitudinal mid-section of said bar corresponding in thickness to the spacing between the glass panes of each pair of panes, there being an air passage formed through said mid-section to allow air to pass from the space between the panes at one side of said muntin bar to the space between the panes at the other side thereof.
