1 This invention relates, as'indicated, to window sash and more particularly to an awning type window structure in which a plurality of sash or ventilators are superimposed and interconnected for synchronous movement.

.Th various advantages of this general type of construction are being increasingly appreciated, partly as a result' of the present great popularity of metal sash such as aluminum sash which is especially adapted for such use. Thi invention is. concerned with improving certain features which have caused trouble and annoyance. in the past whileat the same time providing an assembly which is very simple to install and operate.

A primary object ofmy invention is to provide a window of the type indicated in which only one of a series of ventilators or sash is connected to the supporting frame by means of a. link having fixed points of pivotal attachment, the otherventilators being free-floating.

. Another object of my invention is to provide means whereby all such ventilators will be self-,

locking in open position. A furtherobject is to so mount the. individual sash or ventilators that full four-sided double scaling is obtained when closed.

-Still another object is to provide one set of tie bars for controlling the vertical position of the ventilatorsand another set for controlling their angular osition. I Y 1 v other objects of my invention will appear as the description proceeds.- v

To'the accomplishment of the foregoing and related ends; said invention then comprises the features hereinafter fully described and particularly pointed out in the claims; the following description and the annexed drawing settingforth in detail certain illustrative embodiments of the invention, these being indicative, however, of but a few of thevarious ways in which the principle of the invention may be employed. In said annexed drawing:-

Fig. 1 is a perspective view ofa window employing the sash of my invention;

Fig. 2 is a vertical sectional view thereof show ing the means whereby such sash are mounted.

and interconnected; H l i' Fig. 3 is. a horizontal sectional view taken along the line 3-3 on Fig. 2; I

Fig. 4 is a horizontal sectional view taken along the line 4-4 on E'ig'. 2; g

5 an enlarged perspective view of the lower sash of Fig. 1; and

Fig. 6 is an enlarged vertical sectional view taken through such lower sash and frame.

12 Claims. (01. 189-67) Referring now more particularly to said drawing, the. windowconstruction of myinvention comprises a rectangular frame I into which are mounted a plurality of superimposed swinging

sash

2, 3, and 4. As will appear below, the precise number of sash to be employed is a matter of choice and the proportions and dimensions thereof may be selected asdesired. The top, bottom, and sides .of. frame I may desirably be formed of aluminum angle members having laterally extending side' flanges 5 adapted to engage the outer surface of the wall in which the window is installed. An innervframe consisting of. aluminum angle membersli .is mounted within frame l and serves to provide a neat and pleasing appearance as viewed, from within the building, concealing the sash mounting means from view. The outer edge of such inner frame 6 also serves the additional purpose of providing an inner seal for the sash when the latter are closed. 7

' Frame I is dividedinto vertically arranged sections by means of crossbars 1 and 8, each such bar carrying an outwardly protruding downturned lip or flange 9 and, Ill respectively. A similar lip l l is provided on the upper cross member of frame I. These lips or flanges serve'to receive the outer upper edge of the respective sash toprovide a weather sealwhen the latter are in closed position. H

The three sash proper are. themselves identical although the respective mounting means therefor differ somewhat as explained below. Each sash is rectangular and may be formedof aluminum angle members of Z cross-.section having laterally outwardly extending flanges l2, and peripheral inwardly extending flanges 13 connected by an intermediate web or .wall portion M. The sashv will be glazed in the usual fashion with the' glass'l5 set in putty It. The upper transverse portion of flange I2 is adapted to fit snugly under the corresponding downturned lipsuch as l0 car! ried by crossbar 8 (Figs 2 and 5) and'at the sides and bottom of the sash suchflange engages and overlies laterally extending flange 5 of main frame I. Inner peripheral flange i3 is adapted'to engage the edge of inner frames and at the top of the sash to engage downturned flange llof thecrossbars such as crossbar B. "It will thus be seen that a double weather seal is obtained'fabout the entire circumference of each lsash. It will be 'appreciated that the foregoingdescription'of the sash, while referring principally to the lower sash member 4, is nevertheless equally applicable to the other two sash members! and 3.

' As best shown in Figs. 2 and 6, lower sash mem- 3 her 4 is provided with link members [8 and i9 pivotally connected to frame I at 20 and to the side of the sash at 2|. Only the lower sash is provided with such links.

A pair of lever arms 22 and 23arealso provided pivoted to therespective sides of frame I rate. fixed point 25. The outer ends of such lever arms carry slide followers 25 fitting in slides 26 on the outer sides of the sash. When the sash are in closed position, slide followers 25 will beIlnYtIIe lower end of slide 26 (Fig. 2 .and, when the sash are in open position, such slidefollowers will be in the upper end of the slide (Fig. 6).. Lever arms 22 have ofiset portions 21 beyondiulcrum pivots 24 and vertically extending connecting rods 28 pivotally connect the ends of such ofiset portions 21 of each respective tier of lever arms, thereby insuring that all will move in synchronismabout their pivots 24.

The upper ends of the respective sash are retained within frame I during outward swinging movement of vthe sash'by means ofslidebrackets ZS-pivotally secured to side webs 14 of the sashrat 30- and. traveling in generally vertically extending slideways 3i. As best shown inFig. 6, slideways 3i incline slightlyinwardlyat their upper ends sothatas the upper edge of the sashdescends it will simultaneously .move slightly outwardly. When thesash is returned to closed'position, this movement willlbegreversed while the sash swings about itspivotiifl into vertical position. Thus, as indicated above .and with reference 'to Fig. 2, it wi1l.be understood that because slideways 3| incline slightly inwardly at their upper ends, the

upper portion of the sash is caused'to shift bodily inwardly relativeto the frame during final closing movement of the sash compensating 'for the simultaneous outward swinging movement of fiangeli2-aboutpivot 30 wherebysuchfflange may be inserted behind depending .lip ID to .bear against the outerJface of the upper transverse window .portionthus toiacilitate the obtaining of a tight weather seal without danger of jamming. As "best shown in Fig. 6, pivot 30 projectsabove the .upper edge of the sash a distance substantially equal tothe upward extent of sash flange l2so thatcluring-final closing movement for example, the outward swinging movement 'of the flange is relatively small requiring only slightfinclination of the guideway to offset such swinging movement. Although such arrangement o'fithe pivot with respectto flange 12 is.not absolutely necessary, nevertheless, in most instances the same will ordinarily be. pre'ferredin order that the amount of inclination of theslideways may be kept small. It willbe understood of course that the slidewaysneedbe inclined intheir upperregions-only'thusto facilitate obtaininga tight seal. However, in the interests of economy, such slideways will ordinarily be straight and uniformly inclined as shown 'Brackets29 of the respective tiers of sash are rigidly connected by'means of bars or rods 32 so that the upper edges of the respective sash are required to "move in synchronism.-

It will now be apparent that when the lower sash d is opened to the positionshown in Figs. '1, 5, and=6,=the upper sash are caused to followsuit and will at all timesbeexactlyparallel with lower sash The pair of

links

18 and 19 secured to suchlower sash, however, are all that are required to lockithe entire set in .open position. Whenit is desired toagain close the window, the upper edge of the lower sash may be. grasped and manually elevated whereupon all of thesash will swing closed with a minimum of effort. A lock or catch 33 will ordinarily be provided for the lower sash only to secure them all in such closed position.

Other modes of applying the principle of the invention may be employed,.change.being made as regards thedetails described,- rovldedathe features stated in any of the following claims or the equivalent of such be employed.

I therefore particularly point out and distinctly 'c'laimas myinvention:
