vWINDOW sAsn't.

Application filed December 8, 1926. Serial No; 153,328.

The invention relates to window sash, and

vmore particularly toifabricated or welded steel sash having a ventilator section.

Y von the line 4-'-4'of Fig. 2;V

The object of the invention is to provide a hinge connection between the swinglng ventilator section and the sash frame whereby the ventilator section swings' on the sash frame itself and the use of special hinges is obviated.

A furtherv object of the invention is to provide a sash construction Yin which the swinging ventilator section pivots on theV parts being shown in section;

Fig. 2 is a front elevation view of parts of the sash during assembly toV illustrate the manner in which the ventilator section is inserted into'the sash frame;

Fig. 3 is a ldetail sectional view taken through the sash onthe line 3-3 of Fig.v l,r

parts' being Vbroken away;

Fig. 4 is avertical sectional view'taken Fi 5 is a detail sectional view taken on Vthe line 5 5 of Fig.' l.

Referring to Figs. 1 and 3, the numeral 6 designates the fixed frame section of the sash and it will be noted from Figs. 3 and 5 that this frame consists of side and end T-bars which may be welded or otherwise suitably secured together. at the .corners so as to forma frame. An angle bar 7 is welded or otherwise suitably secured in each instance to the web 8 of the end or transversely extending Trbars-of the frame and angle bars 9 are detachably secured by screws 10, or `othersuitable fastening means, to the webs 11 of the T-bars forming the sides of the sash frame.

The ventilator section 12 is formedby T -bars 13 joined, as by Welding, at their.

lower ends to a transverse T-bar 14 and at their upper ends to an angle `bar 15, which angle bar also has one o f the legs ofv a smaller angle bar'lG welded'forotherwisev suitably secured thereto.V

The inwardly extending flanges 17 of the T-bars forming .the side portions of the frame 6 have flat faced notches 18 formed therein and it is upon the bottom of these `notches that 'the ventilator section 12 is free to pivot or swing relative to. the fixed'fralne of the sash, it being noted that when the ventilator section is in assembled position.

' known vconnections between thev yVentilator' sash section and the-Inainsash'frame being used to hold the ventilator section .in full or partially open position. I

When the-parts are in closed `position `it will be noted from Figs. 3 and 5 that an efcient weathering contact isfsecuredVY since the upwardly extending vleg of the angle bar 16 abuts against the flange 20 of the trans- .verse -bar of the frame 6, the-.flange 21 of the .bar -14 abuts against the yflange 22 ofthe lower transverse bar ofthe frame 6, the

Aendsvof 'laterally extending webs or flanges ofthe bars 15`and14 abut against the angle bars 7, the ends of Websof the bars 13 abut against -the flanges 23 of the Side `bars 9 of the frame 6 and the 4flanges 24 of the barst 13 r,abut against the .flanges -17 Furthermore,V thel upwardly extending leg of the .bar 16 coversthe slots l18,'as shown in Figs.

1 and 3. Y

In assembling the ventilator section in the main frame the bars 9 are removedandthen by. sliding the ventilator section in from the back toward the front, as indicated by the arrow 25, with one of the flanges of the' side bars 13 sliding on the lower side of vthe to interfere with thev free turning movement' of the ventilator section. y

The ventilator section is usuallT provided with window-light sections and oneof the muntin bars 28 for these sectionsV is partly shown.

It will, of course, be vunderstood that `fthe main sash frame may beextended above and below the ventilator section and be provided with window-light sections, yand may 'also have window-.light `sections at kthe sides "of the ventilator section, but since the invention :resides `inthe hinge connections between fthe ventilator :section .and .that portion lof the main frame :sifbrronnding the ventilator section, andtov which sit is attached, further showing of variations in the mam iframe itself are deemed unnecessary.-V Y

I ldesire it to be vunderstood Athat this invention is not to Vbe limited to any 'particular vform lor .arrangement of parts except in so vvfar Vas such limitations ytare vspecified in the claims.

What I 4claim :as any invention is: l. In a window sash, ythe combination with a main. frame lhaving parts forming a ventilator fopening with `sides arid ends :channelshaped in cross section, a ventilator comprising a-ifra-nre havingv '1T-bars at its sides 7and at its lower Yend portion, and oppositely disposed angle bars at its :upper fend portion, one of said `lasten'amed tIrigleq'bars .being offset inwardly from the other angle bar, andY means `adjacent the upper :end portion ofthe ventilator forming :a pivotal "connection between the ventilator section and the main frame whereby the `ventilator section swings `ronaa part of said Imain frame, the webs of said T-'bars having weathering contact with one side Aof 'the channel section of the main frame and theY .flanges of said T-'barshaving'weathering contact with the other sident the-'channel section of themain [fr-ame, the= offset angle bar `also hav-ing weathering contact -withone of the sides of the channel section 'of the main frame-.-A

V2. In a window sash, theV combination :of a marginal frame for a ventilator section having spaced inwardly extending flanges rat the sides of said frame adjacent the top having notches formed therein, a ventilator section having flanges working in said rnotches and `engageable-with said spaced flanges kto form a double weathering contact throughout the entire opening in the marginal frame, vand flanges mounted in said notches and turnable thereon to swing the ventilator section relative to the marginal frame.

3. In a window sash, the combination of a rigid marginal frame fora ventilator opening haviiigdetachable side frame ineinbeis associated therewith, of la ventilator section insertable in said frame on the removal of said side frame members and pivoting on said frame, and means forl securing said side frame members to said frame, the attachmen-t of said side frame members toi said frame preventing the removal of said ventilator section therefrom. 1

4. In a window sash, the combination of a marginal frame for a' ventilator opening providing side :and 'end channels, the side channels including angle bars, means for detachably securing 'said 'angles bars to said frame, and a ventilator section hinged to the fixed `parts of said vside channels to said marginal frame fand having parts in weathering contact with the sides of lthe channels, said ventilator section being -in'- sertable into operative position in said frame on the removal v'of said bars vand being secured therein 'against removal lonthe attachment of said bars.

5. In a window sash, the combination with a main frame having parts forming fa venventilator comprising a frame having:angled bars'at its sides and at its lower end portion, said barshaving Atheir flanges in con# tact .with the frontzflanges of said sides :and

lower end portion and their legs yin contact Y with the 4back flanges of said sides 'and lower end portion, `lsaid ventilator framel'also including -oppositelyrfdisposed angle'v bars at its 4upper end portion, one of whichl .engages in said notches to form a pivotalv connection between the frames, onelfofAsaid'last-named'f V angle bars being offset inwardly from the other angle .fbar whereby "said oppositelyv 'disposed bars provide a double weathering contact with the sides fof the channel 'section of the Vuppferend portion ofthe frame.

6. In a `wind/ow sash, the combination of Ya marginal frame having spaced, inwardly Lextending flanges forming `a channeled frame, there being notches formed in one of `the flanges vat thesidesof the frame vadjacent the rupper 'end thereof, the otherv one of i the flanges at the sides Yof theframe -terminating'below these' notches, :a ventilator frame comprisingisideiand lower end T'bars flanges abutting the otherfset of flanges of .saicl 4marginal frame, ,said ventilator trame with their 'legsrespectively engaging vone set of flanges of the marginal frame and their also including oppositely disposed angle side of the forward flange of said marginal bars forming the upper end portion of its frame and covers the openings formed by Y frame, one of which angle bars is offset rearsaid notches, the other of Which has Weather- 10 Wardly from the front of the other, and ing Contact with the other Vflange at the 5 Works between the spaced flanges of the upper end of the mar inal frame upper end of the main fra-me and has an In testimony whereo,I aiiix my signature. upstanding leg -abutting aga-inst the inner CLARENCE.
