`Application ledl February I0, 119211.

To all whom zt may concern.'

Be it known that I, Hummm* E.` WHITE, citizen of the United States, residing at Youngstown, in the county of Mahoning and State of Ohio, have invented certain new and useful Improvements in Bottom- Hung-Sash Constructions, of which the following is a specification.

This invention relates to an improvement in Ventilating sash construction of the type used in industrial buildings, lparticular y plants requirin extensive ventilation, such as foundries,g ass works, forge shops and the like. l Y

It has been the practice heretofore in meeting the Ventilating lrequirements of plants of the character described, to use a continuous sash construction which is hung or suspended from the top by .axweather tight hinge'so that its bottom swung away from the window opening'to provide Ventilating clearance at'the bottom of the sash only. While this system has been used with satisfaction in vsome instances, it is open to the objection of not providing maximumveiliciency in ventilation where large volumes of air must be discharged quickly, because, the outlet vertically, the most effective, outlet, is greatly if not Wholly obstructed. 'lhat is the top hung continuous sash construction, there is practically no vfertical rather a limited' horizontal passage because lthe sash itself- .from the top,

assumes an oblique position downward and outward, when swung away from the window opening. Dwing to the limitation of the arc of movement of the sash, due to e type of top the mechanical operating connections, the width only lof this horizontal passage may be varied withln thereby keeping most of the the roof of the building and It has alsoheretofore been pron posed to provide a center pivoted sash `construction,` but as that type requires expensive andl heavy structural mountings, 1t 1s objectionablefrom a cal standpoint. 'llhe present invention,.therefore, has primarilyin view the provislon of means for obtainin -a' maximum -ventilating outlet, substantially in the line of natural draft, while atthe Same time preserving the fea- "vide a novel combination of top edge may be A to say, with l outlet, butt arrangement of sash practical and economisemi no. naam.' A

ture of weather-tight joints and simplicity of mounting incident to the top hung sash construction. To that end, it is proposed to4 provide a continuous sash construction hung or pivotally mounted at its bottom edge whereby its upper edge may swing or rock outwardly, and at the same time providing a weather-tight joint at the to of the sash which has heretofore been di cult in view ofthe size and character ofthe sash which are made iny long continuous sections.

A further object of the invention is to proand bottom hung sash units which will afford maximum ventilation by reason of their relatively wide latitude of adjustment, and which also, by reason of this feature, make possible the practical use of the bottom hung sash for all conditions of weathen.

With theabove and other `objects in view which will more readily appear as the nature of the invention is better` understood,

the same consists in the novel construction, combination and arrangementof parts hereinafter more fully described, illustrated and claimed.

A preferred and practical embodiment of the invention is shown in the accompanying drawings, inwhich igure 1 is a vertical sectional view of the side of a monitor of a building showing one construction proposed by the present invention.

' Figure 2 is a view similar to the top and bottom sash units open.

-Figune is a vertical sectional View of the constructionshow-n in Figure 6,- with thebottom hungsash unit in its closed osition.

Figure is a view similar to showing the bottom hung sash in its open positie j Similar reference numerals designate sash unit, in combination with MDW igure ,7 f

llltlll corresponding parts throughout the several figures of the drawing.

In carryin forward the primary object of the invention various structural arrangementsmay be resorted to, in combination with a novel bottom-hung sash construction to provide a weather-tight joint at 'the top thereof when the sash is closed, and which on the other hand will afford a maximum vertical draft outlet or passage when the said bottom hung sash is open. To that end, `the bottom hung sash construction, proposed herein, may be used in combination with any suitable top weathering unit adapted to overlap the top edge of said bottom hung sash in such manner that it will not interfere with the rocking outward of the sash on its bottom hinge. For example, the -said top weathering unit and .joint-forming element, may either be the lower frame plate of an upper top-hung sash unit as shown in Figures 1, 2 and 4, or a separate top-hung apron or str1p as shown in Figures 6, 7 and 8.

Therefore, fundamentally, the present invention proposes to provide abottom-hung sash unit associated with a suitable weatherjoint for its upper swinging edge t provide a wea-ther-tight connection at that point. l

Referring to the embodiment shown in Figures 1 and 2 ofthe drawings, it will be observed that the monitor portion M of a building is partly shown having the roof R supported by the usual structural framework, and provided at its vertical ventilating side with the bottom-hung sash `unit S' and the weather tight joint element carried by a top hung sash unit S. These units may be manipulated by hand or mechanically by operating connections O and O attached to their swingingends as will f that this may be effected by4 any suitable be observed `from the drawings.

Referring first to the mounting of the bottom-.hung sash unit, it will be understood hinge construction, but the preferableY embodiment is shown in the drawings and will This may clearly be and referring thereto it is tor benoted that that sash unit S is hingedly'supported at its A bottom edge while its upper edge may swing outwardly, Aand .the saidunit preferably includes a channeled bottom frame member' 1 whose innerflange 2 has ahinging engagement in the bearing seat a 'or upturned -yflange 3.of a supporting hinge member 4 upon the sai as Y,to-provide -a thoro 65 carried by the continuous sill angle 5 of fthe building framework. By reason of this arrangement,

the entirelower sash is pivotally'hun or hinged at its bottom edge flange/3 in such a manner ulghly practical con-v tinuous hinge joint w ich 1s thoroughly weather-tight because the inner flange of the channel bears uniformly throughout the roove of the hinge member, and the outer ange 6 thereof overhangs and protects the hinge by forming what is in effect an eaves flange to shed or drain the drip-away from the 'oint.

`T e top edge ofthe bottom hung sash unit S is also formed by a top channel member 7 with the roove of the channel arranged to receive tghe upper ends of the vertical muntins and also adequately housing the panels or panes 8 of glass carried thereby. The inner flange 9 of the said top channel member 7 preferably abuts against a sill angle 10 when the sash l is in its closed position. When resting in that position, the outer flange 11 of the channel 7 is overlapped from above by the depending covering fla-nge portion 12 of the weather joint forming element W, which in this form of the invention may be the depending flange of the bottom frame member 13 of the upper top-hung sash unit S. Therefore, this arrangement particularly. adapts the invention for use in combination with sash of the top-hung type to give increased light as well asproviding a wide range of adjustment for the.l draft outlet, and also permitting the use of the bottom-hung sash in stormy weather by affording more or less protection from the elements to the con- Lel/cting supporting flange 19 of a hinge memr 20 carriedv by one of the continuous angles of the building. The upper ysash unlt S is therefore mounted to swing outvwardly at its bottom edge to permit the apron portion 12 of the slll 13 to clear the uppler channel member 7 of the bottom hung sas In using the present construction, the lower edge of thetop yhung sash S must of course be first movedby 1ts operating connection O outwardly a sufficient distance to permit the 'top channel member 7 of the-'bottom hung sash toclear the sealing flange 12 of the sill member` thereof, and then thebottom hung sash S may-be moved t0 any desired position to obtain the required outlet or passage lto permit of the free escape of the air or gases collected within the hood of the monitor. In other words, it is necessaryto partially open the to unit before the lower or bottom hung sa can be o ened, and afterthe bottom hung sash is ree of the weather,

.weather the top sash unit S Yofthe upper sash, and since f shown 1n Figures l and 2 apron or joint, the top unit may be adjusted or reclosed partially to obtain pract1cally any desired degree of ventilation. lln lair the maximum Ventilating position just referred to may be used, but in stormy may be opened wide and the lower sash drawn in just enough to come within the overlapping edge ordinarily sash of this sort is provided on both sides of a building or monitor, one side is usually available in most any kind otstorm.

As further illustrating the range of ap-` plication or the invention, reference may be made to Figures 6, 7 and 8 oi the drawings which show a bottom hung sash S2 having a hinged mounting at its bottom edge-2l upon the continuous supporting hinge member 22 and adapted to be manipulated; through suitable operating means whereby the Channel member 23 of its swinging end may be brought from open position into engage ment with the sill memberQd to permit the weather-prooi" joint elementSa to be brought down into overlapping engagement theren with as shown in ligure 7. rl"he said weather-proof joint element in this form is preferably a, windowless metal strip or plate having at its lower edge `the 25 while its upper edgeis channel with the suspending bearing iiange 26 engaging with the hinge member 27 carried by the framework of the monitor. lll ith this t pe ot construction, that t e maximum Ventilating clearance may be easily and quickly obtained, and as a matter oi :tact this construction is particun larly adaptable .to installations where a quick scavengingn ofthe foul air in a building is of specia importance and where the adjustment or throttling oi the vertical draft opening is case of the complemental top and bottom hung sash units of the same construction as ot the drawings. foregoing, it will be observed although the invention is susceptible covering apron formed into a j From the that of embodiment in various terms, it neverthetil th less involves special .t'eaturesand characteristics chieiamong which are the mounting such a manner thatit hinges .or rocks on its lowertrame member in a thoroughly practical. manner to provide a weather-proof joint at this point, while at e same time the upper edge thereof may be protected by the overlapping of a top ung member having a weather-tight-hinge suspension. AlBy thelprovision ot' the outy opening bottom hun construction the scavenging or chan e vo air trapped within the monitor or wit in the uprpart j ot a building maybe easily and Aquickly i avenue ot discharged by` reason of t e augmented escape adorded through the provision of the relatively extended character it will be apparent' not so material as in thettt lof the opening adorded by the manipulation.
