Abstract

This invention relates to a metal clad window product. The window frame and sash are basically made of milled, elongated wooden members with suitable interconnecting parts, such as mortises and tenons, at the ends of the same. A metal cladding member is attached to each elongated member before assembly of the window parts. The metal cladding member has flanges formed integral therewith which fit into rabbets in the sides of the elongated wooden members forming the frame and sash parts to secure the cladding to the part. The cladding includes an extension at one edge thereof which forms with suitable stop members in the assembled sash, a mounting for a glazing panel assembly. In the case of the window frame, the extension forms the mounting of the weather seal for sealing the sash to the window frame.

Claims

1. A metal clad window sash comprising:

a plurality of rails and stiles forming the sash, each rail and stile being formed by an elongated milled wooden member having front and rear surfaces and an outwardly extending rabbet located on each side of said member between the front and rear surfaces and extending the length thereof;

a metal cladding member mounted onto each of said elongated members by means of a pair of spaced L-shaped flanges formed integral therewith with the free arm of said flange being of a substantial length so as to be fitable into said rabbets on said members only by being slid therein, thereby positioning said cladding member in full contact with the milled front surface of said wooden member over the extent of the width and the length of said member, said cladding member having an extension to the internal side of said flanges;

the ends of said elongated members forming the rails and stiles having mortises and tenons selectively such that the members overlap and fit together at the ends to form stiles and rails of the sash, said metal cladding member having mitered ends which fit together in a mitered butt joint;

stop members positioned on one side of each of the members forming the stiles and rails and spaced from and being parallel to the extension of the cladding members to form a rabbet to receive a glazing panel assembly; and

sealing material positioned on said wooden members beneath the mitered joint of the cladding members and sealed thereto;

the rabbets on the outer edge of said sash having a cross-sectional width greater than the thickness of the engaged end of the L-shaped flange of the mtal cladding member fitting therein to provide a loose fit of the cladding member on the elongated member to permit movement between the rails and stiles and said cladding member in the direction of the plane of the front surface of said wooden member.

2. The metal clad window sash of claim 1 in which the spaced L-shaped flanges of the cladding members are non-flexible.

3. The metal clad window sash of claim 1 in which the flanges and extensions of the cladding members are formed integral with the cladding member.

4. The metal clad window sash of claim 3 in which the cladding member is an extruded aluminum product.

5. The metal clad window sash of claim 1 in which the glazing panel assembly is mounted in the rabbet formed by the extensions and the stop members with a glazing material therein.

6. The metal clad window sash of claim 5 in which the extensions of the cladding members have roughened surfaces facing the stop members.

7. The metal clad window sash of claim 6 in which the outwardly extending open rabbets located on the sides of the elongated members are parallel to one another and disposed in the same plane.
