WINPOW FRAME AND SASH CONSTRUCTION Filed April 12, 1928 ATTORNEYS,

Patented Sept. 8, 1931 UNITED STATES BOYfl. AXE, OF SYRACUSE, NEW YORK, ASSIGNOR TO THE 0. M. EDWARDS COMPANY PATENT OFFICE INCL, OI SYRACUSE, NEW YORK, A CORPORATION OF NEW YORK WINDOW FRAME AND SASH CONSTRUCTION Application filed April 12,

This invention relates to window frame and sash construction in which the sashes are and eflicient construction of sash and guide f therefor by which the sash is weather tight and antirattling. Another object is the are rangement of the latch of the sash holder;

mechanism relative to the internal sash guide. The invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawings in "which like characters designate corresponding parts in all the views.

Figure 1 is a fragmentary elevation of a corner of a window frame and sash embodying my invention.

Figures 2 and 3 are sectional views on lines 22 and 3-3 Figure 1' respectively.

This window sash construction generally comprises a frame provided with an inwardly projecting strip and a sash comprlsmg a hollow sheet metal frame member, the front and rear walls of which are formed with angular internal flanges at the outer edge of the frame member, the flanges having re-entrant 8'0 portions extending toward the center of the frame member in a direction parallel to the front and rear walls and forming a passage for receiving the strip, the re-entrant portions having their inner edges free whereby thgy resiliently eoact with the strip.

ually both the upright frame members and the sill are provided with inwardly 'projecting strips and each stile and bottom rail of the sash has front and rear walls formed 3 with the internal flanges having re-entrant portions for receiving the strips. The strlp along the bottom of the rail isa weather strip, and those along the upright members are guide and weather'strips. I

'45! The top rail, not shown, of the sash may be of any suitable construction and is usually formed of sheet metal. The construction of the top rail forms no part of this invention.

3 is the projecting strip extending lengthwise of each of the frame members, that is, a strip at each'side of the sash.

thereto by a mitre joint at 5. Thus the strips i3, 4 are continuous at their corners so that there are no open spaces through which dust and drafts of air can pass.

Each strip 3 is here shown formed of sheet metal as in the form of a corrugation projecting. from basefianges 6, the latter being secured to the window frame in any suitable manner. Each of the strips 3 is shown as formed with opposing parallel sides connected at the edge of the strip by the crown of the corrugation.

The strip 4 along the sill 2 is substantially the same as the strip 3.

8 designates one of the stiles'of the sash and 9 the rail. Each of these members 8 and 9 are formed up from a single sheet of metal to provide a groove at its inner edge for receiving the glass pane 10 of the. sash and the front and rear Walls 11 and 12 thereof are provided with internal flanges forming a passage for receiving the

stri

3 or 4. These flanges are angular and having portions 13 located at the edge of the sash member 8 or 9 and at a right angle to the walls 11 and 12, and re-entrant portions 14 extending. in a direction parallel to the walls 11 and 12, these re-entrant portions being free at their inner edges so as to resiliently engage the

strips

The sash members 8 and 9 are joined at their corners, as by a mitre joint, and corner irons 15 of any suitable construction are located in the corners of the sash. These corner-irons are here shown as m the form of a U-shaped channel with the opposing sides of the U presented toward the center 'of' the sash and the intermediate portion 16 of the. U-shaped formation extending trans- 4 designates the weather strip on the sill 2 of the frame. Each strip 3 meets the end of the strip 4 and is here shown as connected versely of the frame members between the terminate short of the intermediate portion 16 of the corneriron. One side of the -U- shaped formation is higher at 17 than the other side. The corner irons fit within the corners of the stiles and rail members 8, 9.

- Each stile and rail member is formed with a re-entrant groove 18 for receiving the glass pane, one side of the groove being provided by the portion of a frame member conforming to the portion 17 of the corner iron. The other side of the groove is provided by a removable glazing strip 20 which fits into a re-entrant groove 21 formed in the sash member 8 or 9. This glazing strip forms no part of this invention.

The corner irons also form a mounting for the sash holders which are usually located at the lower corners of the sash. These sash holders form no part ofthis invention and they may be'of any suitable form, size and construction.

. of the window frame.

22 designates the casing of the sash holder mounted on the outside of' the sashat the lower corner thereof and secured thereto as by screws 23 which extend through the walls of the members 8, 9 and through the corner irons.

24 is the lever mounted in the casing and coacting with a latch 25 pivoted at 26 within the corner iron and movable through a slot 27 in the intermediate part of the U-shapedformation of the corner iron-to coact with notches 28 in the adjacent strip 3. The lever 24 is arranged in juxtaposition to a pinch handle 29 on the casing 22;

The corner irons, the glazing strip and the latch mechanism, except for the coacting of the latch with the projection 3 or the rack or notches 28 in the projection of the strip 3 form no part of this invention.

Owing to the resilient re-entrant flanges of the stiles and lower rail, and the projecting weather and guide strips, the sash is held .from rattling and is weather tight, and

owing to the joining of the weather and guide strips at the corners thereof, the weather tight feature is made complete as there are no openings at the lower corners What I claim is:

a frame provided with an inwardly projecting strip havingsubstantially parallel sides, a sash comprising a hollow sheet metal frame member, the front and rear walls of which are formed with angularinwardly extending flat flanges at the outer edge of said member, the flanges on the sash having resilient reentrant portions substantially parallel to and spaced apart from each other and from the front and rear walls of the sash member to which they between .t

...j\cei,ving the strip, the lengthwise edges of the re-entrant portions being free.

2. A window sash construction comprising a frame provided with an inwardly projectare connected with an open spaceem and forming a passage for re ing strip having outwardly extending base flanges, a sash comprising a hollow sheet metal frame member, the front and rear walls sage for receiving the strip, the lengthwise edges of the re-entrant portions being free.

3. The combination of a window frame having a stri projecting from the sill thereof and base anges on opposite sides of the strip, a sash having a hollow sheet metal lower rail having inwardly extending angular flanges at the lower edges of its front and rear walls, and re-entrant portions substantially parallel to and spaced apart from each other and from the walls of the sill with an open space between them whereby 'the free ends of the re-entrant portions are resilient, the re-entrant ortions being a'rranged to receive the pro ection on the sill between them. 4

4. A window sash construction formed with a projecting strip on the sill thereof and lengthwise guides and weather strips on each upright member thereof, the latter base flanges, a sash movable in the frame an joining the endsof the weather strip on the sill, the strips having outwardly extending having hollow sheet metal stiles. and bottom rail, each stile and bottom rail having inwardly extending flanges at their outer edges for abutting against said base flanges, the flanges on the sash having re-entrant p01- tions substantially parallel to and spaced apart from each other to receive the strips and spaced apart from the walls of'the stiles with an open space between them and the bottom rail whereby said portions are resilient to receive the strip, the re-entrant portions being free at their inner longitudinal a edges. 1. A window sash construction comprlsing 5. A window sash construction comprising of which are formed with angular inwardly extending flat flanges at the outer edge of said member, the flanges on the sash having resilient re-entrant portions substantially parg allel to and spaced apart'from each other and .from the front and rear walls of the sash member to which they are connected with an open space. between them and forming a passage for receiving the strip, the lengthwise edges of there-entrantportions being free, a sash holder mechanism carried by the sash .and including a latch located in the hollow lframe member and coacting with the edge of the strip l ocated between the re-entrant portions, the strip having means at its edge within the frame member for coaching with the latch.

In testimony whereof, I have hereunto signed my name, at Syracuse, in the county of Onondaga, and in the State of New York, this tent-h day of April, 1928.
