PA IO FICE mannerisms-75) This invention relates constructions, and more particularlyto casement windowaan 'objectof the invention being to provide a window 7 of this type havinganimproved construction and shape of hollow bars constituting all four sides of the sash, and with the frame bars to insure a weather-tight fit when the sashesare-closed.

- a further object of the vention is toprovide a sash of this character in whichthe metal employed in formingthestiles and railsof the sash may be relatively light and yet will be strong and durable in use. A further. object is to provide improved constructionof frame bars and improved :arrangement of weather-stripping;

'A further object of theinvention is to provide. a subdivided frame construction whose parts can be used interchangeably, without alteration; for swinging sashes orfor fixed window lights or sashes. 5

A further object-is the use of the same frame member throughout and adding a specially designedshape .to it; combination of the 'two' conforming with the combinationof jamb andswinging sashes to create a neat. architectural appearance. v

A further object is to create a combination of.

' window frame and sash; having hinge arrangeso ment 'close to top and bottom of. the hinge stile and having a specially formed clip provided on the sash between the top and bottom hingesfor engaging a member of the frame and automati-i cally holding the sash stile tight to the Jamb to maintain a weather-tight joint.

Figures I, 8, 9, and lilare' views in vertical section, the lower portion of the .bar 4 and a mullionbar 5. The transom bar f and the mullion barsub-divide the frame into panels or sections. As shown in Fig. 1, the upper panel'is used for a flsedtransom A and the two lower panels are used for swinging sashw B and C which open outward. Itis a feature of m the invention, however, that each of the bars I,'

2, 3, l and 5, presents'toward each panel bounded by it an outline "or configuration identical with the outline or configuration of each of the other members. This. configuration is suchthat' any g panel may be readily used-for the mounting of aswinging sash as B or C orthe mounting-o1 a stationary sash or light as- A. -Each of. the bars i, 2, 3, l and 5 is L-shaped. and is provided with short flanges i and I to form a partialiyclosed pocket 8 inthe angle of the L to receive a yielding weather strip 9. The weather strip desirably consists of a strip of felt or -other suitable non-metallic materiaL'as illustrated in mostofthe figures of the drawings, or it may coni sist of a metal weather stri'p'llss shown in Figs. 6 and.9 of the drawings. The weather strip II is made of sheet material bent so as to flt within the pocket 8 and provided with a freely movable web or tongue portion II which is exposed 4o through .the open side of the pocket.

The swinging sashes B and Care. of like construction and each is formed to present the'same contour externally along all four of its edges.

EMIISBSh'iS composed of holiowor tubular bars 5 forming the stiles and the bottom and top rails. .llhe bars l2 are formed of relatively thin metal by extrusion, drawing, or any other suitable process. They are of trapezoidal form; each comprising'parallel outer and inner walls vll and ll, the former being longer than the latter, a connecting wall. I! at right angles to the walls I! and II, and a connecting wall ll extending obliquely outward from the shorter wall II tothe longer wall it so that the sashframe at its as the flange I is provided substantially midwayoutward extension I'Bb beyond the flange [8a edges has a bevel. The bevelled wall It is formed with an outwardly projecting flange ll intermediate its sides for engaging the weather strip 8.

The wall ll engages a flange |8 which extends I parallel to the plane of the window at the inner side of the window frame. ;An extension or flange IQ of the wall i3 engages a relatively short flange l3a of the adjacent frame bar which is located at the outer side of the window and in a plane parallel to the plane of the window. Thus there is providedalong all the edges of the sash three continuous lines of contact between the sash and the frame, the inner and outer lines of contact being formed by metal to metal engagement of parts and the intermediate line of contact being formed by the flange l1 and weather strip 3. The flange 6 is provided substantially midway of the wide inner flange ll, of the-frame, and

of a transverse flange I811.

The weather strip pocket defined by the flanges 6 and 1 occupies, thereforaonly' a minor portion of the angle between the flanges I3 and Ila so that an air space is defined beimeenthe wall It of the tubular bar, I2 and the flanges l8 and I80. of the frame. The flange ll sub-divides this air space into two'separate compartments and eifectively sealsthe compartments from one another. Any air which passes the joint formed by the flanges I3 and l9a-is retarded in velocity in passing through the space at the outer side of the flange I1 and again anyair' thatpassesthe flange i1 is retarded in velocity in passing through the space at the inner side of the flange l-l. Y

The flange I3 of e' h'frame member has an to form a T with the latter. The flanges l8a, I 8b and l3a form an external channel oneach of the frame bars and a reinforcing angle barv I80 of steel or other suitable material is aflixed in the base of the channel with its outwardly extending web or flange disposed parallel to the plane of the window and at a short distance inward from the flange Isa. The angle bars |8c Isa andto partiallyflll'the space between the reinforcing member and the sill or other adjacent building wall element.

The sash bars I2 have integral flanges 23 thereon and the glass panes 2| are held by clips 22 and putty 23,'the bars being formed with dovetail recesses 24 for receiving one end of the clip while the other end of the clip bears against the glass. These clips are hidden by the putty. The

dovetail groove serves not only as anabutment or retaining recess for-the retaining clip, but also as an interlocking recess inside which a portion of the set putty forms a dovetail connection. Thisfeature isadvantageous for the reason that putty'doesnot adhere-well to metal} especially in the case of bronze or other nonferrous metal, so'that sin-interlocked joint is desirable.- r I At the hinges and at anyother points where the may require reinforcement the bars I2 are strengthened by the insertion of metallic angle bars 25.

The transom and mullion bars 4 and 5 constitute double angle bars with the same arrangement of flanges already described. The double angle bars are connected by an internal web 26 which is provided with a recess for receiving a reinforcing bar 21 of stronger material than that I a bar such as illustrated in the mullion 5 may be' employed. In this case the reinforcing bar 21 is completely received in the recess and is held in place by means of a plate 3|. The plate 3| may be sprung orslid into retaining recesses 33 formed in the mullion bar so that the inner face of the plate 3| is caused to lie flush with the inner plane of the window frame. I

The transom bar I is desirablyprovided at the top of the outer side thereof with an outwardly and downwardly projecting curved lip 32 for deflecting water from the upper sash outwardly away from the-lower sash to prevent it from running down between the sashes.

The sashes B and C are shown as outwardly swinging sashes in Figs.'l to 3. Any suitable form of hinge mechanism may be employed but hinges of the type shown and described in United States Letters Patent No. 1,987,516 granted to us on January 8, 1935 are deemed preferable.

Each hinge comprises two

members

33 and 34. The member 33 is secured to the frame and the member 34 is secured to the sash." The member 33 has a straight slot 3itherein, and is also provided with a curved slot 33 at a'n angle to the straight slot. The member 34 base. screw or pin 31 which rides in the straight slot, and a screw or pin 38 which rides in the curved slot 36 so that when the sash is swung open these pins 31 and 33 riding in the respective slots will cause the sash to move in'an outwardly direction or away from-the frame, as indicated by dot and dash lines in Figure 3. The members 33 of the lower hinge are provided with adjusting screws 39 at their outer ends engaging the sill 40, so as to adjust the hinges and properly support the same and the .sash to which they are connected. In

order to preserve a tight engagement between the sash stiles and the corresponding vertical frame members throughout the height of the sash be- "11'." which are-arranged to interlock or wedge behind the flanges 1 of the frame members and the sashes are closed. The engagement between the clips "11 and the flanges! holds the sashes flrmly in contact with the frame members between the hinges. and there is. no danger of the sashes springingut of tight sealing engagement with the frame by-reason of wind premire'or otherwise.- I

The transom-panel of 'Figs. 1 and 2 is'shown as filled with a stationary pane A. It will be observed that-thesame inside totem-tamot'tiie good-ans V inent such tint dthers a stationary pane frame bars is utilized for co-operating with the paneaasisutilizedintheotherpanelsforeooperating with the swinging sashes B and C. When a stationary sash or pane is installed the pockets boundedby the flanges O and I are used for receiving resilient retaining clips In which comprise curved portions imprisoned in the pockets and edge portions for bearing agal'nstthe pane to hold it firmly against the seat formed by the flange ll. Putty is applied in the anglesformed by the frame bars bounding the transom opening and is pressed into the pockets formed by the flanges Band I to provide a secure interlocking engagement with the frame members.

It will be readily apparent that the transom opening is adapted instead to have a hinged transom sash mounted in it while either of the lower panels is adapted, if preferred, to have a sta tionary sash or pane mounted in it. In fact the desired without any'alteration of the frame.. The

frame maybe bricked in for years when a change becomes necessary. In such a case it is not necessary to remove the frame from the masonry and carry it back to the factory for alterations, but the change can simply be made in the field without removing theframe by'applying a new hinge member where a swinging panel is to be substituted, or by removing the hinge member which is present when a stationary panel is t'o'be substituted.

an alternative arrangement for a stationary sash in a frame panel, disclosure is made in Fig. 3a of a stationary sash having edge or boundary members adapted tohe combined with the frame bars illustrated in Figs, 1 to}.

The sash bars of Fig. 3a are all of identical construction whether used for stiles, top rail or bottom rail. Each bar of the stationary come prises an outer flange a providedwith a not adapted to fit into a recess a of the flange Ila.

'Each sash bar also includes a transverse web or. wall b2 provided with a dovetail groove'bl in its.

exposed face. a flange e for setting flange it and a flange cl forming a pane seat, A screw 0 is passed through the ba'seof the dovetail groove bl and threaded into the flange its of the frame. Threaded holes for the 7 screws c and groovesgforthe lipsjare provided inallofthe flanges Ila of the frame so that a-frame ofstandard construction is adapted, without alteration, to be used for mounting either a swinging Or a stationarysash in any. panel thereof. The flanges" band'el formag1azingang'le.. 0iips2l in conjunction with the dovetail grooves-bl "for holding the pane 2! in place and putty I! is applied tocover and conceal the clips.

The arrangement of Figure Sa'can' be a wind is in m th i and;'a weephole maybe provided in the part as;
