Application J une 26, 1947, Serial No. 757,226

This invention relates to Windows, and more particularly to a construction involving metal, and it is among the features of the invention to provide a construction adaptable to new or old buildings, and in the case of the latter to suitably fit irrespective of distortions as commonly found in window openings in the Walls of old buildings. Sash-guide means is provided moreover, which is not too loose nor too tight for proper raising and lowering of the sashes. Other objects and advantages will appear from the following description.

To the accomplishment of the foregoing and related ends, the invention, then, comprises the features hereinafter fully described and particularly pointed out in the claims, the following description and the annexed drawings setting forth in detail certain illustrative embodiments of the invention, these being indicative, however, of but a few of the various ways in which the principle of the invention may be employed.

In said annexed drawings Fig. 1 is an inside elevational view of a window embodying the present invention;

Fig. 2 is a section taken on a plane clear of the inside trim and stops, as at line II, Fig. 4, and illustrating how my construction sits into a distorted window opening as of an old building;

Figs. 3, 4 and 5 are enlarged detail sections taken on planes substantially indicated by lines IIIIII, IVIV and V-V, Fig. 1;

Figs. '6 and 7 are similarly detail sections taken on planes substantially indicated by lines VI-VI and VII-VII, Fig. 1;

Fig. 8 is an enlarged perspective view showing the assembly of an upper corner of the sashguide;

Fig. 9 is a fragmentary perspective view showing a mode of attachment of the insert framing in wood supports; and

Figs. 10 and 11 similarly illustrate forms of attachment in brick and block constructions.

In general, the invention provides insertframing, which in the form of rails 2, 3, Figs. 6 and 5, and stiles 4, 5, Figs. 3 and 4, these being of metal, are attachable in the window opening of the building. In the case of such an opening in a wooden building, the rails and stiles may be secured by screws 1, as indicated in Fig. 9. These rails and stiles are provided with a stop-flange 8 at one edge, e. g. the weather side of the window opening, and by having such stop in the form of a further re-bent margin 9, a recess is provided for the reception of a suitable packing Ill. With some resiliency in the packing, as may be 1 Claim. (01. 189-72) had for instance with packing involving rubber or rubber-like material, with or without fiber reinforce, an adjustability in the seating of the sash-guide G results, and distortion such as found in the window openings of old buildings may be compensated for in the seating of the sash-guide, and a weather-tight joint packing is also assured.

"The sash-guide is also of metal, hollow, and may be formed of opposed outer and inner telescoping channels II, l2, as for the stiles and top rail, and the outer and inner channels I I, [2 for the bottom rail, the overall dimensions being uniform. The inner channels may be of lighter gauge metal than the outer. A peculiarity of the inner channels I2 is that they are provided with grooves M which have an arcuate-base l5 and which provide resiliency in the walls of such grooves for receiving tongues or ribs l6 which project along the stiles of the window sashes S. The latter also desirably are of metal, and while they may be of single-glazed character, generally double-glazing is preferred, and for such the sashes may be formed of nested channels ll, it having flanges I9, 20 to somewhat resiliently grip the panes of glass, suitable sealing material being interposed between the glass and the metal. If the metallic elements as set forth be made of aluminum, brass, stainless steel or the like, rusting or corrosion can be eliminated, also necessity of painting.

The sash-guide, thus as a rectangular frame to be set into the opening and engage against the packing I0 in the flange of the insert framing, may carry the upper and lower sashes U, L, as a convenient unit. For insertion of the sashes, the sash-guide allows of suflicient disassembly, as illustrated at Fig. 8, the holding screws- 25 being arranged to pass through openings in the ends of the stiles and into threaded openings 26 in suitable lugs or cleats 2! carried in the ends of the adjacent rails. Thus, by sufficient spreading of the joint between stiles and rails of the sash-guide, the sashes may be positioned therein and the joints be tightened up. It is noticed that by the provision of projecting ends 29 on the outer channel of the rails, and corresponding cut-outs 30 on the ends of the stiles, an interdigitating form of joint at the corners is attained At the-same time, an opening is left between the end of the rails and the adjacent end of the stiles, whereby ventilation of the hollow sash-guide is secured. As such openings are not externally exposed but are internal, circulation of air and consequent elimination of condensation of moisture is assured in the hollow structures, access of air from the room being permitted by the relatively loose fit toward the room side as contrasted with the sealed fit at the packing on the weather side.

The sash-guide may be held in place by stops 30, 3! at the inside. Conveniently, these may be hinged to the insert-framing, and piano-type hinges 32 are particularly desirable. While the sash guide may seat unattached and be thus held by the stops, i 'iiiostcases it i s efererred to secure the sas'mguideto-the stopnat one side, as for instance by welding to the hinge member 33 which also carries the stop 30. Thereby, on swinging the free stop 3! inwardly out or the Way, the entire sash-guide with its iir'itaihdsashes U, L, may be swung inwardly ir cleaning, etc. I H

For securing the sashes, atenvememsnde 35, Fig. 7, may be mounted on the lower sash 'L,

and having a projectinfg flange 36, may seat under the upper sash U, ;preferably within a protecting narrow sheath '3'! Thumb lugs 38 facilitate -the moving of theslide 35 into locking or unlocking positions with respect to the sashes, and'thumb" screws 3il-permit tightening base, the wallsoi the groove 14 may resiliently frietionallygrip the sash tongues such as to hold the sash in any position without requirementci counterweights. --At the same time, by reason of the resilient engagement," the sashes may be moved up and -slown 'without undue effort.

Instead of continuing the sash grooves M in c s rfe e. lew rfi e S ise iri rrfrred t o mr e ne r c nnel wi the b 9r i nsr i gyahd r h a of the d nt s h w t a were i h e e ra t'irr n be ween. t e; e as n s u d sT iei de d wii ete form of tem. bi irtqk fi l d up hr t.

It is to be emphasized that'tvith; ample clearance or spacing b etweenthe sash-guide :and the frame, as attire-indicated, a compensative fit of the "sash-guide "assured irrespective of any di s tortionin the window frame opening due to settling or sagging oi the building. Furtherinore, with siiehspace there is lan active air circulation "between the "sash-guide and the framing, the openings atj the top and bottom facilitating such circulation; and within the sash-guide itself the hollow space accessible to openingsat-top and bottom also provides circulation. Thus, with such ample circulation in together, in combination with a means for eliminating -sash-counterweights which comprises a transversely-flat web in the inner one of said channel members and a pair of guide grooves formed in it characterized by cross-section in substantially complete circle form with a narrow interruption providing margins in opposition to each other in resilient compression, means for engaging-the transversely-flatperiphery surfaces of the stilesoi window sashes and for laterally reinforcing said groove margins, embodying'the integral portion of said inner channel member web'connectingthe grooves and the integralporticns-of the web laterally of the grooves, and Window sashes having longitudinal tongues sliding-in such grooves.
