This invention relates to improvements in Windows and particularly to Window. assemblies of the awning type.

Awning type window assemblies include a Window frame .and one or more swinging vwindow v-sash sections. It is common practice to provide a vplurality of vertically superimposed sash sec-` tions pivotally supported within the lframe for outwardy 'swinging` movement of the bottom of l, the section and downward sliding movement of*r ythetop of the section; v.Such sections are com- -monly-coupled together by operating mechanism for movement inunison. Inasmuch as such win- .dows are designed to obtain maximum ventilation they are frequently provided in relatively Widefwidths. i 1

The sash operating mechanism is designed to be of light Weight and of Vrelatively small size so `as'to function within a limited space Vand due toilexibility in parts thereof, as for example an operating cross shaft, a sash section may Yclose against the frame on one side but fail to close `.tightly .thereagainst on theopposite side.

-. An object of this invention to provide oper- -ating mechanism for the swinging sash sections which may be readily yadjusted to obtain complete closure of the sections at all points againstA the window frame.

l A further object is to provide .such operating .mechanism with an adjustment which is com- .pletely concealed when `the windowis. closed,

which is yof simple construction and so designed that accurate adjustment can bereadily accomplished.

Another object is to provide operatingmechanism with adjustment means whereby thatside yof a sash .section .furthest removed from kthe operator handle maybe closed against the -vvin- L dow frame ahead of the side of the sash section which .is adjacent to the operator handle in order that rwhen the sash section is drawn down against the frame it will Close completely at all points thereagainst. l y Y y, Other objects, advantages and'meritoriousgfeatures will more fully appear'from' the following description, claims and l,accompanying drawings,

The channels of these .side frame members,V header and sill, openoutwar'dly as shown. .A removable header weatherstrip por tion .26 is provided and shown particularly in Figs. l, 3, 4 and 5. It seats overan upstanding ledge ormedon the lheaderof theframeij Within the frame there mayY be mounted .a plurality of Asash sections, each pivotally "sup-- ported to be swung outwardly. In the particular` embodiment shown, -two 'such sash sections arej The upper section is" indicated byv illustrated. the letter U andthe lower section is indicated by' the letter L. The two sections are-similar andL similarly .supported for pivotal swinging4 movement. #Each section. is shown aszcomprisingametal sash 39 provided with a pane of fr:glass and this sash, is adapted to close over -the Vopen channel of the stationary Window frame, as show-n particularly in Figs. 2 vand 3. Eachsash section is pivotally supported by a pair of fulcrum links @indicated-generally as-z in Figs. 4., canalis.'

-These links are pivoted to opposite sidesofythe sash sectionsas at 34; The ,oppositeen'ds.ofthev links are pivoted to horizontally oppositey points yof the side frame members 20Vvthrough theemployment' of stationary* brackets Y. 36. These brackets 35 are xed to the side frame members as by rivets, brazing or the like. The links are pivoted as at 38 to the brackets as shown generally in Figs. 4 and 5.

Each link is adjustable lengthwise consisting of cooperating end portions ED and 42 as shown in Figs. 9 and 10 speciiically. One end portion 42 is shown as provided with side flanges 44 adapted to slidably receiveY therebetween the opposite end portion 4B. End portion 4U is slotted lengthwise as at 46. 48 is adapted to fasten the twoV portions together at adjusted positions.

adapted to increase the frictional engagement of the fiat faces so that they will better retain their linear adjusted positions.

A retaining screwv The meeting faces of Athe two portions are provided with grooves The two sash sections are adaptedV to beswung outwardly at the bottom and moved ver- .tically downward at the top to adjustable open positions through the use of an operating mechanism which comprises `a pair of slidablev vbars 52 disposed on opposite sides of thewin- Y,dowV frame within the channel side frame members 2li. Retaining plates 54 are secured. as by brazing, riveting or'the like to the 'side frame members of the window and overhang the bars as shown in Figs. and 7 particularly. Each sash section is pivoted to yeach of the bars.

Y A'Each sash section is provided with a pair of armsr` 56, one arm secured to each side of the section at the top as by rivets, brazing or the like. 'Ihe arm projects upwardlyand inwardly of the sash section and ispivoted at 5S to a Ybar 52. It is apparent, therefore, that slidable movement of thel bars 52 will swingv the sash sections to the open or closed positions.,

To actuate the bars slidably vertically, there is provided manual operating mechanism in the,v .form of a hand-crank 60 mounted upon the .outer end of a Worm shaft62 which shaft is supported within a housing'li secured to one side frame member 2U as shown in Figs.r4 and A.5. An arm 65 is provided with gear teeth 68 which mesh with the worm on the shaft 62 to be actuated thereby. This arm is pivoted at as shown particularly in Figs. 4 and 5.

*The outer end of the arm is coupled by a link 12. with a link 'I4 of toggle structure. The

link 74, is mounted upon a cross-shaft 76 to y Y rotate therewith, which Across-shaft extends transversely of the bottom of the window frame and Vis journalled for rotation. The opposite end of link 14 is coupled by the other link 18 y `of the toggle structure with slidable bar 52.

, Itis coupled Ytherewith upon the pivot 58 which .pivots the arm of the sash section to the slidable bar 52 as shown in Figs. 5 and 6.

It isV apparent, therefore, that through opoperation produces'closing of the swinging sash sections. f

In order that eachY swinging sash section may close completely all around against the stationary frame, it is necessary that one be able to adjust the fulcrum links 32. For this reason these fulcrum links are so constructed as to permit of lengthwise adjustment as here- A inabove described. By adjusting one link relative to the other link, litfiisipossible...to insure that opposite sides of the' swinging sash sectionV e lwill both be closed tightly against the stationary frame.

cross-shaft l5. Likewise it has been found desirable to close that side of a swinging sash which is most remote from'the manual operator against the window frame' before closing kthat Aside of the swingingv sash' which is adjacent to the manual operator against the frame""` `I f the side which is adjacent to the operator is' first closed against the frame, it thenbecomes very ,dificult, if not'limpossible, to"pull the remote side tight against the frame. It is,

therefore, desirable to so adjust the operating' mechanism, as for example, by relative adjustment of the 'fulcrum links'tha't theside lof the sash vsectionxwhich isv r'emot'e from the operator be brought against thewindow frame ahead of the opposite'sideof the sash section.V This is shown in Fig. 8, for examplefwherein one side 'of the sash section is shown as'already in engagement with'th'e windowframe whilethe opposite side ofthe sash section is still spaced therefrom. Y. v

When the operating mechanism is arranged to produce this result of closing'the side of the sash remote Vfrom the operator against the frame ahead ofthe sideof the sash adjacent to' the operatorit is-then IJOSSible to continue actuation of the operatorfto draw the'A adjacent side down against the frame. There is sufficient give in' the entire structure vto permit this result; Due to this construction the sash sections may be drawn ltightly against'the window frame at all points. A

What I claim is g 1'.' A window assembly comprising, in combination, a frame, a plurality of vertically superim- 'posed sash sectionsfswingablyV supported within the frame, each sash section 'being swingably supported at oppositeends upon a fulcrum, link,

each of said fulcrum links pivoted at one end to'one side of the sash section and pivoted at the j opposite endV to the adjacent side of 'theframa 'each of said links consisting of two end portions 1 telescopically articulated for longitudinal adjustment of the length of the link, an operating mechanism including a rotatable shaft extending Ytransversely of the frame at the bottom and having an voperator crank coupled with one end of the shaft at one side of the fratrie to rotate the cross-shaft so that the two slidable bars l52 are As the slidable bars 52 are drawn downwardly, the

*upper ends of .the 'swinging sash sections are 'pulled downwardly andthe lower ends are swung outwardly as shown in Fig. 5.V Reverse shaft and having a pair of operating bars coupled with opposite ends of the shaft to be actu- -atedithereby:,andv coupled with the several sash sections to swingably actuate the lsame in unison, y said bars .extending along the inside of opposite sides of the frame between the frame and the sash sections, the fulcrum links ofeachsash section being relatively longitudinally adjustable with respect toleach other to position the side of the sash opposite the operator crank in closer proximity. to the frame than the other side of the sash so that in the closing of the sash section the side of the sash section furthest from the operator crank is closed against the frame ahead of that side of the sash section adjacent to the operator crank.

2. A window assembly comprising, in combination, a frame, a sash section lswingably supported within the frame, an operating mechanism including a rotatable shaft extending transversely of vthe frame at the bottom and having an operator crank coupled with one end of the shaft at one side of the frame to rotate the shaft, a

pair of operating bars coupled with opposite ends of the shaft to be actuated thereby and coupled" with the sash section to swingably actuate the same, said bars extending along the inside of opposite sides of the frame between the frame and the sash section, a pair of fulcrum links swingably supporting the sash within the frame with each link pivotally mounted at opposite ends at fixed positions along the vertical extent of the sides of the sash and frame, and the fulcrum link pivotally mounted on the side of the frame adjacent the operator crank being of a longer length than the link at the other side of the frame thereby permitting the sash during the closing movement to abut the frame at the side opposite the operator crank before abutting the side adjacent the crank.

3. A window assembly comprising, in combination, a frame, a sash section swingably supported within the frame, an operating mechanism including a rotatable shaft extending transversely y same, said bars extending along the inside of opposite sides of the frame between the frame and the sash section, the sash section being swingably supported Within the frame upon a, pair of linearly adjustable fulcrum links adapted to provide as an axis of rotation for the sash a line meeting the plane of the frame at adjustable 1 oblique angles thereby permitting the side of the n along the vertical extent of the sash and frame.
