The frames of the easement4 win- Adows constitute hollow bars 26 which are somewhat L-shaped in cross section and which have webs 21 on their inner faces against which the window panes 28 are secured. The bars 26 also are formed with recesses` 29, and metal clips 3i) are employed to hold the window panes against the webs 21, and the recesses 29 afford accommodation for one end of each clip. The clips, as illustrated clearly in several figures of the drawings, are bowed between their ends and then curved reversely at their ends, one end'of each clip being in the recess 29 and the other end of the clip bearing against the window pane, and these clips are covered and enclosed by putty, or other composition, 30, so as to hide the same, but the clips strengthen the connection and hold the window panes against pressure.

The stationary and hinged window panes are `provided with muntins 3| and 32. These muntins where they cross* are coupled. Each muntin has a main web 33l with relatively wide flanges 34 at one end and relatively narrow anges 35 adjacent their other edge. Where the muntins cross, one muntin is cut out or recessed about threefourths of its width, as shown at 36, which recess extends through the wider flanges 34, and the other muntin is recessed about one-fourth its Width as at 36' to couple to the first mentioned muntin, so that they may be interlocked, as clearly indicated in Figure 4 of the drawings. The main flange 34 of the cross muntins is cut away to accommodate the other flange 34 of the cross muntins, and a reinforcing plate 3| is secured across the joint and to the muntins either by riveting or welding, as desired. The narrow flanges 35 serve as abutments for the window securing clips 30, as shown in Figure 3 of the drawings.

The main frame A is, of course, provided with a suitable abutment web 31 against which the Casement window engages when in closed lposition, and between this abutment web 31 and the bars of the-frame throughout an air chamber is formed which also constitutesa condensation chamber with a weep-hole I9 in the lower bar 31 to allow water to drain to the outside. The lower bar of each easement window has a downwardly curved drip iiange 38 to direct water which runs down the window over the juncture between the window frame and the abutment flange.

The muntins above referred to where they engage the window frame are coupled to the frame at their ends by securing elements 39 of double dove-tailed formation in cross section, located in dove-tailed grooves 40 and 4I, respectively, in the frame and muntins, the elements 39 being disposed laterally with respect to the muntins. The muntins are further secured in the frame by having the main flanged portion 34 cut away from the main web 33 at the ends of the muntins and plates 34' welded thereto and to the frame, as indicated in Figures 5 and 6 of the drawings. By thus cutting the ends of the muntins and providing the plates 34', as indicated,

the webs 42 are securely clamped and the muntins are securely held by this means as well as by the elements 39.

While we have illustrated what we believe to be the preferred embodiment of our invention, it is to 'be distinctly understood that various slight changes may be made with regard to the form and arrangement of parts without departing from our invention, and hence we do not limit ourselves to the precise details set forth but consider ourselves at liberty to make such changes and alterations as fairly fall within the spirit and scope of the claims.

What we claim is:

1. A window construction embodying a frame, crossed muntins located in the frame, said muntins having recesses therein, the recess of one muntin being appreciably longer and deeper than the recess inthe other, and the recessed portions of the muntins coupled together, said muntins having flanges at their edges, the flanges of one crossed muntin being cut away, a strengthening Atogether with the muntins engaging portions of the window frame to secure the ends of the muntins to the frame.

2. In a window construction, a frame, muntins, said frame and muntins having dovetailed grooves therein, the grooves in the frame being disposed directly opposite those in the muntins respectively, thus providing pairs of grooves, and securing elements each being of double dovetailed formation in cross section, there being one of said securing elements engaged in each pair of grooves and said elements being disposed laterally with respect to said muntins.

3. In a window construction, hollow frame bars constructed of relatively light metal, each bar having such cross sectional shape as to provide relatively angularly disposed walls, a strengthening bar located in each of said frame bars and of such shape in cross section as to lie in contact with said walls, and a cap articulated with two of said walls to combine with all of said walls to enclose said bar.

4. In a window construction, a. easement frame including divisional bars joined to provide a recess between them throughout the length thereof, a strengthening bar inserted in and lling said recess and projecting from said recess, and a separate cap covering the projecting portion of said strengthening bar, said cap and divisional bars being articulated.

5. In a window construction, a easement frame including divisional bars joined to provide a recess between them throughout the length thereof a strengthening bar inserted in and filling said recess and projecting from said recess, and a separate cap covering the projecting portion of said strengthening bar, said divisional bars having longitudinal grooves therein, and said cap having flanges on the longitudinal edges thereof engaged in said grooves respectively, to secure the cap in place.
