Y WINDOW SILL CONSTRUCTION Filed July y2, 194e FISA.n
The inner lmember ZZYisHformedwith an inner Patented Sept. 2Q, 1949 2,482,170 WINDOW sILL CONSTRUCTION Foster Gunnison, New Albany, Ind., assigner to corporated, a corporation Gunnison Homes, In of Delaware Application July 2, 1946, serial No. 680,974 6 claims. (c1. 18o-75) The present invention relates to improved features of construction and arrangement of a metal window sill.
One object of the invention is to provide a Window sill whose component parts can be readily formed from sheet metal stock by simple bending or forming operations.
Another object is to provide a window sill construction including at least two metal parts having coacting portions spaced apart by a fibrous strip eective to minimize cold transmission and accompanying condensation and frosting at the inner part of the sill and window.
A further object is to construct, combine and arrange the several component parts of the structures shown in such manner that they individually and collectively perform the functions herein described. l
For a more complete understanding of the invention, reference should be made to the following disclosure, the accompanying drawings and the appended claims. v
In the drawings which .illustrate a preferred embodiment of the invention- Figure 1 is a vertical section through the window sill structure and related parts.
Figure 2 is a horizontal section on line II-II of Figure 1 omitting the window and trim.
Figure 3 is a perspective detail .of the outer sill member.
`Figure 4 is a perspective detail of the inner sill member.
Referring in detail to the drawings, l@ represents any conventional form of studding to which is nailed or otherwise secured any suitable outer sheathing I2, and an inner wall such as plywood panels or the like indicated at I4. At suitable locations in the building structure, window head rails It will span the space between two upright studs I and similarly, a base rail Iwill span the space at about the sill level of the window.
The herein claimed invention relates specifically to the structural features and combination of coacting elements including a novel Window sill formed of two main pressed metal parts referred to herein as the rst outer sill member 20 and a second or inner sill member 22. The .outer sill member is of generally stepped configuration, comprising a substantially vertical wall 23, a substantially horizontal wall 24 fixed to the top of wall 23, and a ledge portion 26 projecting substantially horizontally from the bottom of wall 23. The walll 24 constitutes the inner offset marginal portion of the outer sill member 20.
upwardly offset marginal portion comprising a substantially horizontal wall 30 connected by an inclined portion 28 to a substantially horizontal portion 32 having a downwardly bent lip. Interposed between the inner marginal oiset extremities of the outer and inner sill members 2E) and 22, there is a strip of fibrous material 34 such as felt or the like. Wood screws or other fastening devices such as indicated at 36 penetrate holes 38 and 39 respectively formed in marginal portions of the outer and inner sill members 2S and 22 and serve the double function of anchoring the sill members to the supporting member i3 and compressing the fibrous strip 34 to make a tight joint between the sill members. The brous strip 34 also functions as a heat insulator particularly effective to prevent the transmission of cold from the weather exposed member 26 to the interior sill member 2.2. Such structure is advantageous in a metal window sill structure-because it prevents condensation and frosting at the inner part of the window sill and also minimizes the frosting of the window in cold climates.
While not limited thereto, the sill construction shown and described is well suited for use in buildings employing metal Window frames. By way of illustration, I have shown a metal window frame of substantially Z-shape in cross-section including substantially horizontal web portions 4i? and 42 at the top and bottom of the window anclinner and outer upright flanges 44 and 46, The lower web portion 42 is seated on top ofthe marginal portion Si] of the inner sill member 22 and the outer flange 46 extends downwardly parallel to the vertical wall 23 of the outer sill member 2S. The clearance space between outer sill member 26 and the ange 46 is preferably filled with a body of caulking compound as indicated at 48, thus making a weather-tight joint around the window frame and preventing infiltration of air between the metal window frame and the metal sill parts. A similar lling of caulking compound such as indicated at 52 and 52 may be provided at the top of the window frame and adjacent the sides thereof. The metal window frame is equipped with a conventional form of hinge lug 54 supporting a pintle 56 which passes through a lug 5B extending out from the metal sash B which has suitable window glass 62 secured thereto in any conventional manner.
The lower web 42 of the metal window frame is provided with suitable holes to permit the passage therethrough of the screws 36 andthis window frame may be secured in place by the same screws that are used to anchor the sill members to the support or separate fastening means may be utilized to secure the frame to the mem-r bers I6 and I8 and to the upright studs l0. On the inside of the building, I will usually provide a substantially trough-shaped member 6| Whose inner wall is separated from the panel I4 by a spacer 62, the member 6l being secured in place by screws ory other fastening devices 64 which penetrate 'the panel Il 'and enter the support f8. Any suitable wood, metal or plastic trim such as indicated at 66 may be secured adjacent the inner flange 44 of the metal winowzframeldn order to make a neat nish.
While I have described"guite/"specicllytire preferred embodiment of `the YAinvention"here'in illustrated, it is to be understood that the drawings and descriptive matter are ttoibe interpreted in an illustrative, rather than in a limiting sense.
