Serial No. 427,573.

This invention relates to casement windows or the like, and the primary object of the invention is to provide'a metal or other construction of this kind embodying a frame and a sash window or like member of such cross-sectional shape as to present tongues on the side, top and bottom members of the sash or like member, and grooves in the side, top and bottom members of the frame adapted to snugly receive said tongues of the sash or like member when the latte is closed, thereby forming a thoroughly weathe proof window or the like without the employment of separate weather strips.

A further object is to provide a casement window of the above character which is exceedingly simple and rigid in construction and economical to manufacture and install.

The invention consists in the novel form, combination and arrangement of parts hereinafter more fullydescribed, shown in the accompanying drawings, and claimed.

In the drawings:

Figure 1 is an exterior'elevational view of a casement window embodying the present invention.

, Figure 2 is an enlarged horizontal section on line 22 of Figure 1, partly broken away; and a Figure 3' is an enlarged vertical on line 33 of Figure l, partly broken away.

Referring in detail to the drawings, the invention is illustrated in connection with a single casement Window comprising a metal window casing or frame 5 and a metal window sash 6 that is mounted on the jamb or members of the frame by means of inges 7 so as to swing outwardly.

The window frame 5 comprises side memhere 8 and 9 connected at their upper ends by a metal head 'member 10 and at their lower 7 The side member 8 constitutes a jamb and comprises a main body portion formed with spaces. simi-. lar outward longitudinal corrugations 12 presenting interior grooves and flat co-planar portions 13 at opposite sides of the corrugations, and having an inturneo stop flange 14: on its inside marginal edge and an outturned stop flange 15 on its outside marginal edge. The side member 9, head member 10 and sill member 11 each embodies a main body portion of fiat-section and having an inturned stop flange lla on its inside marginal edge and an outt-urned stop flange 15a on its outside marginal edge. Each of the flanges 14a and 15a has an inward corrugation l6 presenting an exteriorly facing groove. As shown, the frame 5 may be set in a window opening 17 formed in a concrete wall, and fastened in place by means of screws 18 passing through the members of the frame and into wooden strips 19 embedded in the walls of said window opening. The free marginal portions of the flanges 15 and 1564 may also be embedded in the wall of the window opening, as clearly illustrated in the several views.

The sash 6 embodies a framehaving a pane 2O suitably fastened therein as at 21 and comprising

side rails

22 and 23, a top rail 24, and a bottom rail25. The side rail 22 is similar in general form to that of the side frame member 8, its outward body corrugations 26 presenting tongues adapted to be snugly received by the grooves or corrugations 12 of said frame member 8 when the sash is closed. In a like manner, the side rail 23,top rail 24 and bottom rail 25 are similar in general form to that of the

frame members

9, 10 and 11, the corrugations 27 in theirwmarginal flanges presenting tongues adapted to be snugly received by the grooves or corrugations 16 in the stop flanges of said

frame members

9, 10 and 11 when the sash is closed.

In view of the above, it will be seen that the joints between the corresponding frame and sash members will be effectively sealed by the interfitting pairs of tongues and grooves, thereby providing a substantially weatherproof window without the use of separate weather strips. Moreover, the construction is exceedingly simple and durable,- as well as economical to manufacture and install.

While the device has been particularly described in connection with a single casement window, it'is obvious that it may be readily adapted to double windows or to doors; In the case of double windows, the side frame member-9 will simply need be changed to take the form of" the side frame member 8 to provide jambs at both'sides of the frame, suitable provision being made to seal-the joint between the two-sashes hung in the frame.

"What I claim as new is :'-1- 1. In a metal casement window comprising a frame and a sash mounted therein to swin outwardl the frameand sash having cooperating side jamb and-sidemembers each comprising ,a main body portionformed with spaced outward longitudinal corrugations and having an inturned stop flange on its inside marginal edge and an outturned stop flange on its outside marginal edge, the corrugations 'of the jamb member presenting interior grooves-in the body portion thereof the corrugations of the side sash member presenting tongues on the body portion thereof adapted to be snugly received in said grooves of the'jamb member when the sash is closed, the frame and sash further having cooperatingtop and bottom members each comprising a main bodyportherein to swing outwardly, the'frame and sash having cooperating side jamb and, side members .each comprising a main body portion formed with spaced outwardlongitudinalcorrugationsand having an inturned stop flange on its insideflmarginal edge'and an joutturned stop flange on its outslde margmal edge, the corrugations of the amb memberpresenting-interior grooves in .the

7 body portion thereof the corrugations of the side sash member presenting tongues on the bodyportion thereof adapted to be snugly received in said grooves of the jamb member when the sash is closed, the frame and sash further having cooperating top and bottom members each-comprising a main body portion of flat section and'havingan inturned flange on its inside marginal edge andan outturned flange on its outside marginal edge,

the corrugations of the flanges of the last named frame members presenting exteriorly facing grooves therein, and the corrugations of the flanges of the lastlna'med sash members presenting tongues adapted to be snugly received in saio grooves of theframe member flan es when the sash is closed, the outturned flanges of the frame members having their free marginal edges embedded in the Walls of the window opening 7 N In testimony whereof I afliX my signature.
