VNDOW CONSTRUCTION.

Application led June 20, 1919.

Be it known that I, Ronnnr S. DRUMMOND, a citizen of the Unit-ed States, residing in the borough. of Manhattan, city of New York, county of New York, and State of New Yorl, have invented certain new and useful Improvements in Tindow Construo tion, of which the following is a specification.

My invention relates to the construction of metallic window sash and relates more particularly to improvements in the means for providing weathering around the mar ginal edges of a pivoted or otherwise transversely movable ventilator section. The principal object of my invention is to increase the lighting capacity ot' a window section of a given size and having therein a ventilator, without complicating the con struction or increasing the expense of manufacture, and in fact, to make the changes from the standard forms of construction of the sash members as slightand few as possible. Heretofore, commonly, the adjacent stationary and movable sash bars or muntin members have been placed adjacent to but out of contact with each other, and weathering, either single or multiple, has been. provided by means of an interposed weathering strip secured to one or the other of the sash bars or muntins, an angle strip being employed for single weathering and a channel strip for double weathering. ln such a construction, light of course is excluded to the extent of the width over all of the two adjacent slightly spaced sash bars, which on their adjacent sides are commonly provided with the usual flanges forming glazing rebates of substantially standard construction, and with which, particularly in double weathering, the weathering strip may cooperate. Another object of my invention is the saving of metal.

In carrying out my invention, I bring the adjacent stationary and movable muntin members or sash bars close together so that their adjacent rebateforming glazing flanges, or other adjacent flanges, have a cooperative overlapping relation for thereby effecting weathering without the employment at this place of a separate weathering strip, as has been done heretofore, and also, by reason of the bringingof the sash members closer together than heretofore, less light is excluded. ln order to effect this Serial No. 305,556.

weathering relation of the usual glazing flanges of the standard muntin or sash bar construction, or of other similar flanges, I bend or distort these flanges, preferably bending one inward and one outward so as to provide complementary oppositely disposed co-operative weathering surfaces, such as oppositely inclined flat contact surfaces. ln the case of ventilators which are hinged or pivoted between their margins, these cooperative weathering flanges are distorted in opposite directions at opposite sides of the pivots, thereby to provide for the swinging of the ventilator section on its pivots while preserving a proper weathering relation of the adjacent flanges of the sash bars, My invention more particularly includes features of construction and combinations of 'parte'. as will hereinafter appear.

I shall describe the metallic sash con` struction illustrated in the accompanying drawings as an embodiment of my invention, and shall thereafter point out my invention in claims.

Figure l is an elevation as viewed from the outside of a metallic window section, having a horizontally pivoted ventilator therein, parts being omitted at the top and bottom.

Figure 2 is an enlarged horizontal section on a plane above the pivot line and indicated by the line2-2 of Figure l as viewed from above.

Figure 3 is a similar view below the pivot line and indicated by the line 3-3.

Figure et is a view similar to Figure 2 illustrating the application of my invention to single weathering instead of the double weathering construction shown in the preceding iigures.

Figure 5 is an enlarged transverse section of one of the muntin members which has not been bent or distorted for weathering purposes.

Figure 6 isa view similar to the upper right hand part of Figure 2 and illustrates 'the application of invention to produce weathering between a muntin member and a sash frame member at the jamb, instead of between two muntin members shown in Figures l, 2, 3 and et.

In Figure 5 is shown a cross-section of a solid metallic muntin member or sash bar, such as l prefer to employ in the metallic window sash construction embodying my ico invention. This muntin is of isha-pe, havmg a web or stem l, and oppositely projecting glazing flanges 2, which with the stem l, form glazing rebates or rabbets. Each of these rebate-providing glazing flanges 2 is con'iparatively thin and oit wedge-shape and is preferably similarly tapered on both sides as shown. This muntin or mullion such as is illustrated in Figure 5 may be employed for both the vertical and transverse nonmarginal sash bars in the construction shown in Figure land as there indicated by the reference numeral 2, there employed to designate the glazing flanges shown in Figure 5. These solid metallic muntins are originally rolled to the form shown in Figure 5.

In the particular metallic sash construction embodying my invention illustrated in Figure l, the middle part of the complete window section is a movable ventilator part shown as mounted on pivots 3 to swing inward at the top and outward at the bottom, on a horizontal axis or pivot line. rlhis pivoting is effected between adjacent stationary and movable muntins, these inuntins being originally of the construction and transverse configuration illustrated in Figure 5, and which also appear non-marginally in Figure l, but whicl'i at the ventilator edges have been slightly modified' so as to produce, in accordance with my invention, the weathering relation between these adjacent stationary and movable muntins.

The marginal stationary muntin at the right of the pivoted ventilator section appearing in Figures l, 2 and 3, similarly to the muntin shown in Figure 5, has a stem or web l and at the right side thereof has a glazing flange`2, but at the left side thereof, 'the glazing flange such as appears at the left in Figure 5, as shown in Figures l and 2 has been. distorted or bent outward to form a weathering flange l; and below the pivot 3, this flange which was originally the glazing flange has been similarly distortedior bent inward to form an inner weathering flange 5, as appears in Figure 3 and .in the lower part of Figure l. Correspondingly, at the left side of the swinging ventilator section appearing in Figures l, 2 and 3, the stationary' muntin has a usual stem l and glazing flange 2, but above the pivot 3 of the ventilator .section`r what otherwise would be a similar glazing flange is bent or distorted outward, as appears in Figure 2 at the left and in the upper part'of Figure l at the left, to form an outer weathering flange 6, while the lower 'part of this same flange is distorted or bent inward as appears in the lower part of Figure l and Vin Figure 3, to form an inner weatherin;r flange 7. j n

At the right side of the ventilator section the marginal muntin thereof has a usual stem or web land an inner glazing flange 2, but at 'the right or outer side of this muntin what otherwise would be a similar glazing flange above the pivot 3 has been bent inward to form an inwardly movable wea-thering flange S, shown in Figure l at the top, and in Figure 2; and below the pivot 3, this same flange has been bent outward toprovide an outer outwardly movable weathering flange 9, as shown in the lower part of Figure l and in Figure 3. rlllhe inwardly movable weathering flange 8 has an outer inclined flat weathering or sealing surface co-operative with a similar flat inclined inner weathering surface of the stationary weathering flange -l on the stationary muntin bar, to which the movable muntin bar is pivoted at 3' as above noted, Similarly below the pivots 3, the outer movable weatheringl flange 9 of the movable muntin bar at its inner side has a flat outwardly inclined weathering or sealing surface which is co-operative with a similarly flat inwardly inclined sealing surface provided by the stationary weathering flange 5 on 'the stationary muntin below the pivots 3, as is clearly shown in Figure 3 at the right.

lt thc left side of the swinging ventilator section, the movable marginal muntin has the usual tern l and a glaisli'ig flange at the right side thereof. At the left of this inuntin what otherwise would be a similar glazing flange has been bent inward to form an inner inwardly movable weathering flange l0, as indicated at the left and top in Figure l and as clearly shown at the lett in Figure 2. Similarly, below the pivot 3, s shown at the left in Figures l. and 3, the ame flange has been bent outward to 'form i outer outwardly movable weathering flange ll. rllhe upper and inwardly movable weathering flange 10 of the movable muntin bar at the left of the ventilator section has a .flat inwardly inclined outer sealing surface (2o-operative with a similar dat outwardly inclined sealing surface on theI stationary weathering flange 6 of the adjacent stationary mun fn.' Similarly below the pivot 3 the outwardly movable weatherflange ll is provided with an inner outwardly inclined flat sealing surfacev co-optive with and movable outwardly away from the similar inwardly inclined outer flat sealing surface of the stationary weath` ering flange 7 of the adjacent stationary muntin.

ln the drawings, the swinging ventilator section is shown as in the closed position. lllhen this' swinging ventilator section is ,fpenefh the upper movable weathering S and l0 thereof will `move inward ai. from the stationary weathering flanges l and G respectivelyg'and similarly the lower movable weathering flanges 9 and ll Awill move outward away from the sta- S) ll liso vtor

tionary weathering tlanges 5 and 7, as will be clear trom an inspection ot Figures 2 and 3 in connection with Figure 'lL j It is to be particularly noted as a feature of my invention that the'adjacent `movable and stationary muntinsare brought ycloser together to the extent ot the weathering overlap between tlielweathei'ing flanges, and also to the extent ot the elimination ot' the usual clearance space which heretofore com monly hasbeen `lett between project-ing adjacent glazing tlangcs, `similar to the 'flanges lt is evident that the bringing closer to get-her of these inuntins orv sash bars into overlapping relation 01"' their lianges will cause them to efclude that much less light than they would it placed merely adjacent| to each other with their tlangesnot. in overlapping relation, but opposite to and slightly spaced from` each other, as conimonly has `been done heretofore, a special weathering strip then beingprovided ttor closing the clearance spaces between the opposed tlanges. It is to ,be noted ot my iii-- vention that the co-operative weathering flanges provide between them an unusually wide weathering joint, by reason ot the great width. ot the flat contacting sealing surfaces. lt is obvious that the weathering' arrangement ot my invention may be equally well employed' regardless ot whether the pivots of the ventilator section are at a middle point thereoh'or are at an` end thereof; and also whether these pivots are along horizontal or vertical lines, all ot these forms ot pivotingbeing common in the art. i

YWhen multiple weatheringis desired, an angle strip l2 is employed, this strip being substantially the same as heretofore has been employed for single weathering. This weathering strip l2 above the pivots 3 is secured to the stein 1 ot the movable marginal inuntin at each side of the swinging ventila` section, as shown inFigureQ; and be` low the pivots 3, at each sideol the swing;- ing ventilator section, this angular weathering strip l2 is attached tothe stem l ot the adjacent stationary muntin, as shown in Figure 3. These angular feather strips l2 are shown as secured in plaoeby ineans of rivets 13, although they may be otherwise held. for example by welding, as is common in the art. The outwardly projecting flange ot each ot the upper movable weather strips l2 'forms a weathering seal with the inner surface of the web l ot the adjacent stationary muntin.l as shown in Figure 2, and similarly the inwardly projecting ilange ot each ot the A lower stationary weather strips l2 forms a similar weather-` ing seal with the inner surface ot the lower part of the web l ot the adjacent movable marginal muntin of the swinging ventila tor as shown in. Figure 3.

llhere only single weathering is desired, these angle strips l2 may beomitted, as is l `illustrated in Figure where, as there ap- "pears,4 the co-operative'relation of the sealing surfaces on the overlapping?flanges of the adjacent movable and stationary mun tin without the necessity of employinga special weathering strip, as has been doneheretd tore 'tor single weathering.

.lleretotore commonly tor single weathering :iira'nglestrip similar. to the strip l2 has been employed, and tor double weathering a channel strip has been employed. For double weatheringiny invention dispenses with one leg or vflange otsuch a channel strip and `enables the other `leg` to be made My invention therefore results in the saving of material to the extent that tor double-weathei'ing an angle strip such as l2 employed instead` of the usual heavier `channel strip, and for single weathering the usual additional angle strip is omitted al-` together.

Figijure 6 shows that the weathering arrangement ot' my invention may be equally irelleniployed at the outer edge o a window set-tion or at the jainb, and that it is not` limited to the middle part ot the window section as illiistratedfin `the preceding tig'- ures. lThe construction shown in Figure 6 is the same as appears at the right in yFigure 2, excepting that instead of the stationary muntins there appearing. a stationary trarne` member ot channel term is shown, ycomprising middle web 14. outer marginal inner and outer flanges l5 and 16,y and an inwardly projecting glazing flange which has been distorted or bent outward to form a weathering iiange'l similarv to the weathering flange l appearing at the right in Figure 2, andv having a similar function. The other parts illustrated in Figure 6* may be and are shown as ot the same construction as oiiears at the right in Figure 2. @bviousl i t if s,
