Metal cladded window products

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.

What we claim is: 
     
       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.]. .Iadd.inner and outer sides .Iaddend.of said member between the front and rear surfaces and extending the length thereof; a metal cladding member mounted onto each of said elongated .Iadd.wooden .Iaddend.members by means of a pair of spaced L-shaped flanges formed integral therewith.Iadd., each flange having a free end .Iaddend.with the free .[.arm.]. .Iadd.end .Iaddend.of said flange being of a substantial length so as to be fitable into said rabbets on said .Iadd.elongated wooden .Iaddend.members only by being slid therein, thereby positioning said cladding member in full contact with the milled front surface of said .Iadd.elongated .Iaddend.wooden member over the extent of the width and the length of said .Iadd.elongated wooden .Iaddend.member, said cladding member having an extension  .[.to the internal side of said flanges.]. .Iadd.along its length which extends beyond the width of the front surface adjacent the inner side of said elongated wooden member.Iaddend.; the ends of said elongated .Iadd.wooden .Iaddend.members forming the rails and stiles having mortises and tenons selectively such that the .Iadd.elongated wooden .Iaddend.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.]. .Iadd.the inner .Iaddend.side of each of the .Iadd.elongated wooden .Iaddend.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.]. .Iadd.to seal said joint.Iaddend.; the rabbets on the outer .[.edge.]. .Iadd.side .Iaddend.of said .[.sash.]. .Iadd.elongated wooden members .Iaddend.having a cross-sectional width greater than the thickness of the .[.engaged.]. .Iadd.free .Iaddend.end of the L-shaped flange of the .[.mtal.]. .Iadd.metal .Iaddend.cladding member fitting therein to provide a loose fit of the cladding member on the elongated .Iadd.wooden .Iaddend.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 .Iadd.elongated .Iaddend.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. .Iadd. 8. A metal clad window product comprising: a plurality of elongated members interconnected to form the configuration of a window frame or sash, each of said elongated members having front and rear surfaces and first and second sides located between said front and rear surfaces and a rabbet extending in each of said first and second sides for the length of said elongated member;   a metal cladding member coupled to each of said elongated members to form a metal cladding surface over the front surface of each elongated member, said metal cladding member including a metal member having a width and length sufficient to cover said front surface wherein said cladding member is in full contact with said front surface, first and second flanges integrally formed on said metal member so that said flanges are spaced from one another and each extend the length of said metal member, and a metal extension integrally formed with said metal member adjacent one of said flanges and extending the length of said metal member adjacent to the first side of said elongated member;   each metal cladding member being coupled to one of said elongated members prior to their interconnection to form said configuration solely by slidably engaging said flanges in said rabbets from one end of the elongated member until the metal member is positioned over the front surface of said elongated member along the entire length and width of the elongated member;   each metal cladding member being formed to have mitered ends which fit to form a mitered joint with adjacent metal cladding members on the elongated members forming said configuration; and   sealing material positioned between said metal member and said elongated member along each mitered joint to seal said mitered joints. .Iaddend.   
     
     
        .Iadd. 9.  The metal clad window product of claim 8 including a sealing material coupled to said extensions along the length of said extension. .Iaddend..Iadd. 10. The metal clad window product of claim 8 further including a stop member coupled to the first side of each elongated member and being spaced from and parallel to the extension of the metal cladding member on said elongated member, each said stop member and extension forming a rabbet to enable said configuration to receive a glazing panel assembly. .Iaddend. .Iadd. 11. The metal clad window sash of claim 10 further including a sealing material located adjacent the extension of each cladding member along its length to form a seal between the extension and a glazing panel assembly when a glazing panel assembly is disposed in the rabbets formed by said stop members and extensions. .Iaddend.
