UNTED STATES THOMAS I. SHEAN, 0F CHICAGO, ILLINOIS.
WINDOW-SILL CONSTRUCTION.
Application filed January 29, 1923.
To all fia/wm t may conce/ra.'
Be it known that I, THOMAS P. SHEAN, a citizenof the United States, residing at Chicago, in the county of Cook and State of Illinois, have 'invented certain new and useful Improvements in Wrindow-Si1l Constructions,- of which the following is a specification.
This invention relates generally to metallic building structures and particularly to a specialvform of construction designed as a sill portion for wall openings.
n The general purpose of the invention is the provision of a structure of the sort specified which is adapted to be fabricated out of sheet metal or other suitable material and which will be elfective to prevent, to a material degree, the entrance of dust from the sill portion into the building when the window or other closure is open.
With constructions now employed a very considerable quantity lof dust which deposits 'on the sill portion of the wall opening remains there in a very favorable situation for its being blown into the building through the wall opening when the window or other closure is opened or, being open, when it is struck by gusts of wind. The present construction is designed to afford an arrangement whereby such deposit of dust may be trapped so that its entrance into the building is prevented.
For the purpose of illustration I disclose in the present application, and in the drawing forming a part of this specification, one form of structure in which the invention may be embodied, but it is to be understood that the illustrative purpose thereof is not to be construed as limiting the invention which I propose to secure by Letters Patent, short of its true and most comprehensive scope in the art.
In the drawingl Fig. l represents a sectional elevation of the construction with associated parts of the building structure; and
Fig. 2a horizontal section, on reduced scale, taken substantially on the line 2-2 of Fig. 1.
The invention will best be understood by reference to these illustrations in detail. Let it be understood that the reference numeral l designates the building wall portion forming one side of the wall opening, 2 the wall nish sill constituting the bot- Serial No. 615,484.
tom exterior portion of the wall opening and 4 the interior sill or finish sill of the window casing. In the window frame is mounted a suitable closure for the wall opening, the same being here represented by the lower rail 5 of a sliding sash, in which is supported a pane of glass 6. Form-A ing a part of the window frame and extending across the width thereof is the dust sill which includes the bottom plate 7 suitably anchored in the wall structure and extending under the wall closure and outwardly over the wall sill. This plate pref ably isk inclined outwardly to secure the desired drainage, and it extends inwardly to form the floor of a dust chamber 8, the f walls and top of which may be provided by suitably shaping the sheet of material of which the plate 7 is formed to afford an upwardly extending inner wall 9, a top wall l() and depending outer wall 11. The latter terminates shortyof the plate 7, leaving an intervening gap or slot extending the full Vwidth of the frame. The walls of the chamber thus formed are reinforced by a matching strip which may be secured thereto by spot welding, which matching strip preferably affords a seat portion 12 upon which the wall closure may seat when closed and a stop portion ll4 arranged to overlap the inner margin of the wallclosure. In the case of sliding or outwardly swinging sash, the lower frame member thereof is vpreferably provided with a lapping flange 15 arranged to' abutthe outer surface of the matching strip 12 when the closure is shut. This arrangement of the associated portions 'of the sash and sill afford a weather tight joint between the two.V
Vith the parts thus associated it will be observed the front slot or opening of the chamber 8 intervenes between the exterior sill portions on to which dust may deposit and the lower margin of the window opening. As a result, dust deposited on or blown across the sill portions will be impelled into the chamber 8 and will not be deflected upwardly toward the window o-pening. During the time a window is closed there normally is a considerable deposit of dust on the sill, and when the window is opened there is frequently a pronounced inrush of air into the building through the window opening. The present arrangement prevents the dust being carried into the building upon such contingencies. The dust thus blown into thechamber 8 will strike the inner wall 9' and be Vdeflected upwardly and `then forwardly against the outer wall 11. Impact with the latter will again deflect the dust downwardly and inwardly so that its escape from the chamber will be inhibited. .Y
In order to accommodate the discharge of dust from the chamber 8,. discharge ducts 16 may be provided at the sides of the wall opening and overlappingl the sill, which ducts have communication at their rear ends with the chamber 8 and extend to a point wheretheir front ends will discharge over the outer margin of the sill 2. Concave deiiector plates 17 may be disposed in the inner corners of the chamber 8 and the inner end openings of the ducts 16 are preferably of greater area than the outer end openings. This construction provides an arrangement whereby dust trapped in the chamber 8 may find an outlet through the ducts 16, through which it is impelled by the wind blowing into said chamber, and discharged at the outer ends Vof the ducts over the margin of the outer sill. In `this way the dustchamber 8 will be automatically cleared. It will be observed that by virtue of the construction the outer face of the rail 5 is in substantially the same vertical plane as the outer face of the chamber wall. This avoids any intervening shoulders or ledges on which dust? might deposit vbetween the chamber opening and VYthe wall opening.
This invention maybe embodied Vin window frame constructions of various sizes,
without encroachment upon the clearance of the wall opening and without impairment of theclosure.
I claim:
1. In structure of the sort specified, the combination Vwith a sill of means affording a dust chamber having a dust inlet at the upper surface of the sill and below the bottom of the wallj closure.
2. In frame construction for wall closures, in combination, an exterior sillrextending below therrwall closure and means affording a dust chamber between the sill andthe wall closure, said chamber having a dust inlet along the upper sur-face of the sill.
3. In closure construction for wall `openings, in combination, an exterior sill extending below the wall closure, a housing forming a dust chamber along the inner margin of said sill, a movable sash member arranged for abutment with said housing and having a Yvertical flange overlapping the outer wall thereof.
11. In wall closure structures, in combination, an exterior sill, a housing affording a dust chamber at the inner margin thereof, said housing being open along the upper a dust c hamber Vat the inner portion of the sill, said housing having an opening for admission of dust from the sill and a conduit communicating with saidl chamber and leading across the sill for discharge of dust from the chamber over the sill.
7. In wall closure constructionin combination, an exterior sill, a housing affording a dust chamber at the inner portion thereof, said housing being open to receive dust from the sill, anda conduit communicating with said chamber so that wind blowing into the chamber will discharge dust therefrom through the conduit.
8. In window structure, Vthe combination with the exterior sillV and .the closure, of means forming a vdust compartment, said compartment being provided with an external inlet extending longitudinally of the sill and situate between it and the closure, said compartment being closed oli from the interior of the building. Y
9. In window structure, the combination with the exterior sill and the closure, of means forming a dust compartment having an yinlet opening situate between the sill and the closure and a discharge opening separate from the inlet.
10. In window structure, the combination with the exterior sill and a movable closure, of means Vforming a dust compartment, said compartment having an external opening along the upper surface of the sill below the closure and extending the full width of the latter.
In testimony whereof I have `hereunto-set my hand.
