Application March 29, 1937, Serial No. 133,487

12 Claims.

This invention is an improvement in metal window framing construction for mounting and operative installation for use in connection with the sash. frame and housings therefor of my companion a'pplications'filed herewith Ser. No.

133,485 and Ser. No. 133,486.

'It consists in its entirety of stationary window framing portions comprising top and bottom horizontal substantially similar head and sill members, and intervening vertical side framing por-' tions. These members are preferably made of extruded metal sections, for mounting in a window opening and in connection with the sash and housing elements above referred to. V

In. the accompanying drawings showing one preferred construction: f n

Fig. l is a sectional perspective view showing portions of a complete installation, including b'oth upper and lowersash and housing portions in 23 their operative relation to the surrounding fram- Fig. 2 is a sectional plan view on the plane of the section line II-II of Fig. 1;

Fig. 3 is a vertical sectional view on the line IIIIII of Fig. 2;

Fig. 4 is a cross section'on the line IV-IV of Fig. 1;

Fig. 5 is a sectional perspective view illustrating separability and adjusta'oility of portions of the framing construction;

Fig. 6 is a sectional view like Fig. l, showing means for connecting the inner channel and master plate to the surrounding framework.

While the framing construction may be used with other designs or forms of sash and housing, it is shown in combination with improved metallic forms, as in my applications above noted.

The light 2 is held within a surrounding frame between separable front and back members 3 and 4, and mounted in a housing by connecting wedge or dovetaili. The housing is thus fixedly connected with the sash frame so that they movetogether, and each housing is composed of a top bar 5, a bottom bar 1, these being reversed as. to

the upper sash housing, and side bars 8. The top bar 6 of the lower housing and the bottom bar 6a, of the upper housing are provided with interengaging meeting rail sealing ribs 9 and 9a.

The bottom bar 1 of the lower housing and the top bar 1a of the upper housing are grooved cdgewise for closing engagement with rib ID of ,the lower sill and rib Illa of the upper head member,"-preferably in connection with aflanking rib H and Ha respectively.

Side bars 8 of each housing are alike and are similarly grooved for sliding engagement with ribs or tongues I2 of the window framing. They are also provided with sockets I3 for connection with sash cords M which pass over pulleys l5 and connect with sash weights H3 in the usual manner. I

The window framing construction with which the raising and lowering housings and their sashes are combined and mounted for'operation is, like them, of metal, and preferably composed of extruded sections. Such framing is mounted within w the window opening of a building upon the wooden or other opening defining construction comprising a lower sill framing member A, an

' upper head framing member B, and side framing members C. 5

The lower metal sill and upper inetal'head framing members are generally indicated by the letters a and b respectively, and are substantially the same, in reversed positions as shown, Fig. 1.

Each consists of an inner channel shaped one 20 piece section of thin sheetmetal having longitudinal side flanges H and a connecting Web section 18 deflected inwardly at the middle as at [9, for clearance of thejoint connection of the outer retaining and finishing housing-engaging por- 25 tions. 7

The flanges ll engage groovesin the wood or other framing A and B as at 20 for fixed 1ocation therewith.

The housingengaging portions consist of a 39 pair of fiatsections' 2|, 22,- ea ch having an outer flange 23 terminating in an inclined terminal edge 24 held in position by any suitable securing means, as screws ,25. Sections 2| and 22 have interlocking connection with each other within 35 the deflected channel H! by tongue 26 and groove 2i engagement, each meeting edge being properly shouldered as shown for firm bracing connection.

By such construction web sections Hand 22 are maintained in alinement against deflecting 1 pressure in either direction, assisted 'by inner channel web l8. a

Section 22 is provided with the integral ribs or tongues i0 and 1 Land forms the inner halfof the lower sill framing, and in reverse position. 5

forms the outer half for the upper sash housing,

as shown.

The pair of intervening oppositely located metal side framing members are generally indicated by the letter 0, and are mounted between 5 the under and overlapping ends of the sill and head members a and b.

Each consists of a channel shaped one piece section of thin sheet metal, having longitudinal side flanges28 also engaging grooves in the wood 55 or other framing C, as at 29. The connecting web section 3|] is deflected and shouldered as at II for holding engagement against lateral movement of a master plate 32.

Said plate forms the base mounting of the laterally adjustable tongues or ribs I2 and their bases 33, and of the main side walls 34 having the sash cord shrouds 35. These, as shown, extend over and cover the side bars 8 of the sash frame. Master plate 32 is provided along and within its opposite edge portions with undercut grooves 36 for holding engagement by interfitting inclined wedging strips 31 of each side wall 34 when they are in their normal outermost position and 'the parts are assembled for use, as in Fig. 4.

Bases 33 of slide ribs l2 have tongue and groove connection as at 38 with the side walls 34 when both are in normal position, and both bases 33 and their ribs are normally in operative relation to the sash housings.

Bases 33 are held ,insuch outwardly spaced position by a pair of wedging bars 39'having converging sides 40 bearing against theinner in- .clined edge faces 4| of bases 33.

, Each bar strip 33, shown as removed in Fig. 5, is .insertible in clearance opening 42 of plate 32 and held by several screws 43 tapped into plates 32 and the middle preferably reinforced portion as in Fig. 5, for access to the sash cord at either side.

An especial advantage in such removability of side sections 34 is that the entire sash housing and sash may be removed together with guide ribs 12 and their "bases 33, without disturbing other portions. It will be understood of course that both-sections 34 at opposite sides vof one sash must be removed together to effect removal of a sash housing.

By making 'bar 39 in two sections, upper and lower, either may be adjusted by properly shifting one of the sash housings.

Channel 30 and master plate 32 are secured to the side framing C by elongated screws 44, Fig. 6,

and the endmost angular casing members 34 by screws 45 through their terminal flange edges 46, or by any other. suitable means. 7

Sash cord pulleys l5 are pivotally mounted in shrouded brackets 41 secured on the inner upper faces at each end of channel webs ID by a pivoting and tightening screw 48 with the opposite end .of the bracket base retained under a limiting flange 49, as in Figs. 2 and 3. By such mounting the pulleys and brackets may be accurately located for proper vertical positioning of, the two depending strands of cord I4 in connecting its terminals with the housing bar 3 and sash weight is respectively.

The channel webs 18, 2|, and 22 and brackets 41 are perforated as at 50 for passage of the cords l4.

It will-thus be seen that by the construction of the several combined elements and members of the window framing the three main metal units a, b and c are capable of very accurate mounting and cooperation with each other, and that they provide for operative mounting within a' window opening and for easy access to the working elements whenever desired.

Being made of comparatively light, thin, preierably extruded metal shapes, as of aluminum, the entire construction may be reduced to minimum dimensions externally, and in their entirety present an attractive, ornamental and durable equipment.

The several parts may be easily standardized and made to suit various standard typesas to size, etc., for different dimensional window openings.
