Original application July =15, 1954, Serial No. 443,675, now Patent No. 2,804,954, dated September 3, 1957. Diviged and this application July 25, 1955, Serial No. 523, 55

This invention relates to windows, particularly metalframe windows. Some features of the invention are particularly applicable to windows in which the sash slide horizontally, while other features are as readily usable with windows of other types.

The general object of the invention is to improve and simplify the construction and mounting of the sash in metal-framed windows thereby reducing cost of manufacture, promoting free sliding of the sash, and improv ing the weather seal.

In carrying out my invention, I employ a metal window frame, having spaced, peripherally extending anges projecting into the window opening to provide channels or grooves in which the sash are slidable. In the case of a window having horizontally slidable sash, the sill of the window carries a friction-reducing metal strip which is grooved for sliding reception of the sash and which can be readily removed from the frame for purposes of cleaning when the sash are removed. To permit removal of a sash, the head of the window frame is arranged to permit upward movement of the sash to the extent necessary to allow the lower edge of the sash to clear the groove in such strip, thus permitting the sash thereafter to be lowered out of association with the frame-head. To take up clearances necessary for such operation and provide a weather seal, the upper rail of each sash is equipped with buttons of antifriction material which are spring-pressed against one wall of the sash-receiving groove to force the rail into sealing engagement with the opposite groovewall. Desirably the latter groove-wall is the intermediate one of the three flanges defining the two sash-receiving channels and is embraced by a friction-reducing metal strip.

Like the window frame, the sash rails are metal, are mitered at the corners of the sash, and at each corner the stock of meeting rails is formed, as by a stamping operation, to provide walls parallel to the miter joint, and screws extend through such walls to hold the meeting rails together. The meeting rails of the two sash are provided with interengaging anges and with a locking device for locking the sash in 'closed position.

Other objects and features of the invention will become apparent as the` detailed description of a preferred embodiment thereof proceeds.

The accompanying drawings illustrate the invention:

Fig. 1 is a` vertical section through a window in a plane perpendicular to the wall in which the window is located;

` Fig. 2 is a horizontal section through the window of Fig.1; A A

Fig. 3 is a fragmentalvertical section through the head of `the window frame; t

Fig. 4 is a vertical section on the line 4-4 of Fig. 3;

Fig. 5 is a fragmental elevation of one corner of a sash with portions of the joined rails broken away;

Fig. 6 is a fragmental vertical section illustrating details of a preferred form of window lock;

Fig. 7 is a fragmental elevation corresponding to Fig. 6; and

Fig.. 8 is a fragmental isometric view illustrating the mounting of the keeper of the window lock.

The window illustrated in the drawing is of a type embodying horizontal slidable inner and outer sash. Conveniently, the head, side jambs, and sill of the window frame are all made of extruded metal stock having the same cross-section. Such section embodies a web 20 adapted to extend generally in a plane perpendicular to the plane of the window opening. Projecting into the window opening from such web are three spaced

flanges

21, 22, and 23 defining two channels in which outer and inner sash, designated in their entirety by the

reference numerals

24 and 25, are slidable. The middle ange 22 is preferably provided along its edge with a head 22 which increases the space between the sash 24, 2S. The interior flange 23 is desirably located at the interior edge of the web 20 and is coplanar with a ange 26 which projects outwardly. The web 20 continues exteriorly of the window beyond the outer ange 21 for a distance and there is provided with anoffset portion 28 which, in the assembled frame, provides a rabbet groove for reception of storm sash. Outwardly beyond the offset portion 28, the stock has a flange 30 extending in a plane parallel to that of the window opening, and from the outer edge of such ange there extends interiorly of the opening a flange 31. In the bases of the channels defined by the

anges

21, 22, and 23, the web is formed with inwardly opening longitudinal grooves 32 which (Fig. 2) are adapted to receive resilient sealingstrips 33 co-operating with the adjacent ends of the sash. Such sealing strips will ordinarily be provided only in the side jambs, as other means are employed for providing a weather seal along the other edges ofthe sash.

Each sash of the window comprises a pane of glass 35 bordered by top, bottom, and side rails all formed with inwardly opening channels to receive the edge of the pane and a sealing strip 35' which embraces the pane-edge. The lower rail 36 of each sash is provided exteriorly with longitudinal flanges 37 through whichthe weight of the sash is supported from the sill of the window frame. The vertical sash rail 38 at the jamb end of the sash is conveniently provided with a longitudinal ange-extension 39 serving as a nger piece for use in sliding the sash within the window frame. The vertical end rails 40 remote from the jamb-ends of the two sash are meeting rails and are provided with obliquely disposed flanges 41 which, in the closed position of the sash, engage each other to provide a weather seal. window frame, the various sash rails are conveniently formed as aluminum or aluminum-alloy extrusions.

At the corners of each sash, the joining side rails are conveniently mitered and secured together in a manner illustrated in Fig. 5. As there shown, the web of the rail stock is deformed inwardly to provide parallel walls 48 perforated for the reception of a screw 49. One of the holes provided for each screw is a clearance hole while the other is of smaller diameter, and the screw is preferably of the self-tapping variety.

To reduce friction and facilitate sliding movement of the sash, l preferably associate with the sill of the window frame a bearing strip 51 (Fig. 1) formed of a metal i,

different` from that of the lower sash-.rails 36.A `If such 21, 22, and 23 of the frame-sill and two upwardly opening grooves into which the lower sash-rails extend. The strip 51 lies loosely on the upper edges of the

flanges

21, 22, and 23 so that it can readily be removed for cleaning Like the side members of the ases-,e46

hereinafter. 'To provide for the escape of any moisture collecting in the sash-receiving grooves of the strip 51, suelr grooves; are provided in their Bottoms with holes 52, and the ilan-

ges

21 and 22. are provided adjacent the web 270"- witlr openings' through ywhichany collected moisture can escape to the outside of the window frame.- Iiy dc sited, the' exterior edge of the strip` 51 may terminate in a" ffange 54- co'nceafing the openings in the ange 21 but spaced upwardly slightly from the web 20 so as not to trap any moisture. The lower sash rails iit snugly within the grooves of the strip' 51 to provide a weather seal.

To' reduce' sliding friction at the top of the sash, the head 22" of the Hnge 22 on the top' member of the window' frame) be embraced by a bearing strip 55 (.Fig. 3*); they edges of which are bent around the head 22; to h`o`ld the Strip` place'. To facilitate removal of the sash, the upper s'as'h rails do not fit snugly between the bearingr strip 55 and the

flanges

21 and 23. To provide a weather seal between the upper sash rails and the bearing.

strip 55",` I may use the arrangement illustrated in Figs. 3 ar'1`d4. As there' shown, the web of each upper sash rail is' oif=set downwardlyV at intervals to provide recesses each receiving the head of a wear button 57 having a shank 58 projecting through an opening in that ange of the sash-rail which is remote from the frame-flange 22 for engagement with the other sash-guiding frame-

flange

21 or 23. The head of each button 57 is recessed for reception `of a compression spring 59 which urges the button-shank 58 Vinto engagement with such frame-flange 221 or 23'and, by reacting on the sash-rail, resiliently forces the latter into contact with the bearing strip 55.

As willv be clear from Figs. 1 and 3, there is a substanti'al'r gap between the upper sash rails and the bases ofthe channels in the frame-headwhich slidably receive them.. The extentv of this gap4 is such as to permitv each sash to be raised until the lower sash rail. clears the walls of. its groove in the bearing. strip 51, whereupon the lower edge: of the sash can be swung inwardly and the sash lowered to remove it from the window frame,

as for purposes of washing. Conveniently, the heads of the buttons 57 are non-circularand engage the sash-rail to prevent rotation of each button about the axis of the shank 58, and the upper edges of the button-Shanks 58 are chamfered to facilitate re-insertion of the sash in the frame.

A preferred form of means for locking the sliding sash in' closed position is illustrated in Figs. 6, 7, and 8. As there shown, the meeting rail. 40 of the inner sash carries a lockebase 65 upon which is pivotally mounted a camlike lotkintgv member 66 eti-operating with a keeper 67 secured to the meeting rail 40 of.- the outer sash. The keeper 67 is conveniently formed of a rectangular plate of resilient metal, preferably stainless steel, and is provided at one end 'with an opening 68 for the reception of the dam of the locking member 66. At its opposite end', the keeper 67 is bent back on itself, as indicated at 69 (Fig. 8`) to embrace' the edge of the vintermediate ange on the meeting rail 40, the web of the meeting rail being perforated adjacent such flange to receive both the body of the keeper and the in-bent portion 69. At that end of the keeper remote from the opening 68 slots are provided defining a tongue 70 which is struck from the plane of the keeper, as shown in Fig. 8. The keeper is brought into association with the meeting rail 40 of the outer sash passing it through the slots in the web off such rail. lThe slot which receives thebody of the keeper has a' width only slightly greater than the thickness of the material from which the keeper is formed so that, as` the keeper approaches its final position, the-voue" struck tongue 70 engages the side of such slot and is resiliently deected into the plane of the keeper. When the keeper reaches its iinal position, the free end of the tongue 70 clears the sidel of' the slot, and the tongue springs vback to its original position. to engage the web of the rail 40 at the side of the slot and prevent removal ofthe keeper from. association with: the rail.

In the window shown in the drawing and above1 described, both sash are slidable. However, many' features of my invention areA usable with equal advantage in a window having' one sash slid-able and the other xed.. One' such latter arrangement is shown in4 my priorrv copending' application Serial. No; 443,675, tiled July I5, 1954, which became Patent No. 2,804,954 on September 3, 1957, of which this application is a division.
