WILBUR B. BURKE @MYOMWM ATTORN EYS Patented Oct. 16, 1951 UNITED. STATES PATENT OFFICE Windows, as commonly constructed, have certain well-recognized handicaps.' Thesashes are unduly cumbersome and heavy. Their glass expanse transmits heat scifreelyV that thead'dition of storm windows is resorted" to in winter'. 'They are awkward to clean on the outside vunlessa ladder be used, and in efforts at cleaning from the inside, not all of theglass can be ei'e'ctively reached. In such efforts at doble'gl'ai'ng as have been attempted;A the attaining of 'a sufliciently tight' seall to prevent "moisture accumulation and condensation inthe space' between the glass has not bena'deqately successful. Added to this is the general tendencyof sashes tostick or befmoved with diliicul't'y. In accordancewith'the present invention, however, rconstruction may be had which obviatesV such vdifiiculties; Aand desirably effective nieans 'ofy providing ample ill-umination without undue' radiation losses, and' with particular'convenience of operation, may be prol vided'.- Other advantages in detail Ywill beap'- paret from the following description. i

To the accomplishment of thel 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 settingiorth in detail certain illustrative embodiments of the invention, thesebeing indicative, however, of but a few of the various ways' in which the principle ofthe invention maybe employed.

Equipmentl in accordance with the present in.- vention may be applied: to new or old Window frame openings. 'A sash guide 2, Fig. 3,` is secured to the window frame 3L by suitable means, for example, by screws 4 passing through stops 5l and flanges G of the sashguide. Desirably, the sash guide 2: is made of metal, and sheet metal of suitable gauge can be stamped or rolled to provide the sash-guiding grooves. If the metal be of aluminum, brass, stainless steel or the like, freedom from corrosion or rusting is assured, and painting iis! also unnecessaryv on such parts. Desirablly, the sash-guiding grooves in the `sashguide yZrmayA be made narrower Lthan the thickness of the sash4 S, and` may be relatively narrow grooves 8 to receive a corresponding tongue 9 pro,- jecting from .the sash at its side or rail portions. lf such tongue 9be hollow, the space maybe filled with alubricant packing, as for instance wicking saturated 4with' a suitable lubricant, and through holes .I:|,.Fig. 4i, at spaced intervals, feed of lubricant. to the: guideway may insurepsmonth operation in the sliding ofthe sash up and down.

The sash is formedof inner and outer charinels .l3, l.4.secured together l,by Asuitable means, fornnstanee spot welding, andthe flanges l l.6 are spaced suiciently to receive the `margin of the ,glass pane :(3. preferably, the flanges l5, IQB, are Slightly resilient and .1.1.1 :the .une'lzedA State may tend to Aclose sornewhatlmore' closely than with ,the glass .in place',A aidthus 'a' uniformly Y* t nt may b'e'attainxd'; Usually, a sealin cans I 8.1s4r desirably also" included," arid whilethis may' talizfe thefform of' a rubber ch'a'n'- nel or thel'ike embracing' tlieedge of the g jss pane, preferably I employ a sealing medium Vof plasticinat'erlal which is initially fluent and'ca-n be injectedmt th-space frqm instep artefice glass is set in position, such" plasticsealingmaterial then subsequently setting tosucierit solidmay be of cementitious character thinned by a volatile solvent which evaporates, or more desirably it may be a thin synthetic resin which will set. The top edge of the sash is closed by the similar nested channels I3, I4, Fig. 4, fastened to the side or stile portions by angle brackets I9. It will be noticed that by the provision of the channel members I3, I4, as described, the flanges I5, I 6, at each edge provide seating for double glazing, as shown most clearly in Figs. 2, 3 and '7, and the flanges being rebent toward each other thus hold the glass between opposed edge contacts or line contacts such as to preclude irregular warping and loosening. The glass may be set in position under conditions standardized to a minimum of moisture content for air included between the panes before they are sealed at the joints, or where desired, a vacuum may be provided between the panes. In either case, by reason of the efficient mount and sealing, a doubleglazed structure may be free from excessive condensation which has been common in doubleglazed sashes heretofore attempted.

As a further refinement, for rendering the sash particularly accessible for cleaning, the metal sash guide may be carried on hinges to allow swinging of the entire assembly into a position of easy accessibility for both sides of the glass. Thus, as illustrated in Fig. 11, the sash guide 2 may have a hinge mounting 22 along its edge, preferably piano-type hinges being used, and thereby the entire assembly can be swung inwardly, for instance, to allow convenient cleaning. To permit such swinging, the stops 5 are also hinged to swing out of the way, as indicated in dotted lines at the right end of Fig. 11. Also, sufficient clearance for the swinging of the rear edge of the sash guide may be assured by slightly cutting back the adjacent window frame, as at 23, Fig. 11. With this mounting, it is desirable to provide backing strips 24, of metal or wood, preferably wood, secured between the flanges of the sash guide 2 by suitable means, as screws 25; and the stiles and rails of such backing are preferably assembled such as to allow of slight adjustment for possible inequalities in the window frame opening being equipped. Thus, the joining corner ends of the stiles and rails, as shown at Figs. 12 and 13, may have saw-cuts 21, and flat L-shaped metal pieces 28 may be inserted therein, suitable screw fastenings or the like 29 being set through the wood and metal assembly with the desired dimensions as determined by the minor adjustment requisite to assure a proper fit. Desirably, a weather seal 30, Fig. 10, may be provided on the window sill 3I, and if this be of slightly yieldable material, such as rubber, sponge rubber, and the like, particularly close tting may be attained. A sheath 32 of sheet metal may be applied over the strip 30, affording protection and maintenance of its placement. If de sired, the flange of the sheet metal sash guide or support 2' may be extended horizontally as at 33, so as to lap over the seal when the sash support with its included sashes is in its normal position, closed. On the top of the lower sash a weather seal 20 may be provided to cooperate with the upper sash. If desired, the bottom sheet metal sash guide or support may also have grooves 38 to receive a corresponding tongue 39 on the bottom of the lower sash.

Other modes of applying the principle of the invention may be employed, change being made as regards the detail described, provided the fea- 4 tures stated in any of the following claims, or the equivalent of such, be employed.

I therefore particularly point out and distinctly claim as my invention:
