TENSIONING DEVICE FOR STORM WINDOWS Filed June 29. 1949 I N V EN TOR. M/a/fer M Ara/n A T TOIP/VE X Patented Oct. 21, 1952 a I UNITED STATES ?ATENT OFFICE I TENSIONING DEVICE FOBJSTORM WINDOWS WalterM Krantz, Ferndale, .Mich. Application. June 29, 19.4.9, Serial No. "101,980
aoiaims. (01. 20-55) This. invention relates tostorm windows and more particularly to combination storm windows wherein glazed and screened sash are removably positioned in mounting frames which in turn are in communication with said channel and means in said channel registering withsaid opening I01 yieldingly increasin the effective thickness of the said sash whereby the samemay be tightly fitted ina storm window frame.
A still further object of the invention is the provision of a storm sash having a, channel in the edge thereof and an opening in said sash in communication with said channel and a ball in said channel in registry with said opening and extending partially therethrough, and means in the said channel for yieldingly holding the said ball in the said opening whereby the same may be tightly fitted in a storm window frame.
The storm sash tensioning means shown and described herein comprises a simple and efiicient device formed in combination with a storm sash having a longitudinally extending channel in the edges thereof for increasing the effective width of the sash to enable the same to be self-supporting and self-sealing in a channeled frame in which it may be positioned so that a weather-tight seal is obtained by the said sash and said frame.
With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.
The invention is illustrated in the accompanying drawing, wherein:
Figure l is a fragmentary view of a portion of a storm sash frame and sash therein.
Figure 2 is a vertical section on line 2-2 of Figure 1.
Figure 3 is a horizontal section on line 33 of Figure 2.
Figure is an enlarged detail of the tensicning means.
Figure 5. is a top plan View taken on line 5+5 of Figure 4.
By referring to the drawings andlrFi'gu'res 1, 2 and 3 in particular it will be seen that a storm sash frame it) has been disclosed whichis adapted to be positioned inor on awindow opening and which has a pair of spaced flanges 'I'I' and I2 thereon which define a channel 13. for the-reception of a storm sash Hi which in turn has a channel it formed in its marginal edge. Thestorm sash M includes a panel of glazing materials It secured in the sash M, by metalv spline H as is customary in the art or as shown in my Patent No. 2,505,553.. The two peripherallyv extending flanges formedbysaid channel 15011, the edge of the sash l4. arereceived between 'saidj'flanges vI I and it. As appears in the drawings, theflanges H and I? are so spaced that the sash is received snugly therebetweenfbut a slight'spacing is provided by which binding or seizing is positively prevented. Howeventhis spacing, which is common in storm window practice, while necessary to prevent seizing or binding, normally permits leakage of air around the sash l4 and thus partially defeats the purpose of the storm window since it detracts from the insulation value thereof.
The present invention relates to the forming of one or more openings 58 in the sash and estab-' lishing communication with the channel l5 therein and positioning a ball l9 partially through the opening 88 so that a portion of the ball l9 extends beyond the plane of the sash l4 and thereby increases the effective width of the sash M at this point. A leaf spring 29 is positioned between the innermost portion of the ball 59 and the part of the sash i l defining the other side of the channel l5 so that it yieldably positions the ball IS in the opening H8. The ends of the leaf spring 20 are sharpened as at 2l--2l so that they dig into the material of the sash id and thereby locate the leaf spring 28 with respect to the ball 19. As will be evident from the drawing, the ball l9 will be of a diameter slightly larger than the diameter of the opening it and yet it is sufficiently small that it will extend through said opening and slightly beyond the outer surface of the flange M in which the opening it? is located. The thickness of the flange I4 is likewise substantially less than onehalf the diameter of the ball in order to make it possible for the ball to extend therethrough. The
spacing of the inner surfaces of the flanges l I and l 2 with respect to the outer surfaces of the flanges I l is great enough to permit the ready sliding of the flanges l4 between but is sumciently small that the ball I9 will engage the flange II and will by it be pressed against the spring 20. Altemately, locating means may include the construction disclosed in Figure 5 of the drawings wherein a small opening 22 is formed in a leaf spring 23 to partially engage a ball 24. Either of these constructions will efficiently position the ball IS with respect to the opening [8 in the sash M. It will be obvious that when one or more of these devices are positioned in the sash i4 and the sash l4 moved into engagement in the channel l3 of the frame [0, the sash will be securely and tightly positioned therein so as to insure a weather-tight closure with respect thereto.
It will be observed that the spring 20 holds the ball l9 firmly in the opening l8 so that the entire unit is self contained and will not come apart even when the sash is removed from the supporting frame. This is of advantage in assembling the structure and is of particular advantage wherever one of these units is used on an end of a sash which will be removed from the frame when the window is open.
It will thus be seen that the several objects of the invention are met by the tensioning device for storm windows disclosed herein.
Havin thus described my invention, what I claim is:
1. In a storm window sash adapted for support between a pair of spaced, parallel frame flanges, the combination comprising: a pair of peripherally extending, spaced, parallel sash flanges adapted to be received between said frame flanges, and an opening through one of said sash flanges; a leaf spring element engaging the other sash flange at a point opposite said opening and having a portion thereof intermediate its ends positioned to intersect the projected axis of said opening; a ball of diameter larger than the diameter of said opening but small enough that it will extend through said opening and beyond the sash flange containing said opening, the thickness of said sash flange being substantially less than onehalf the diameter of said ball; said leaf spring being curved away from said other sash flange by such a distance that it engages said ball and holds it against the edges defining said opening.
2. In a storm window sash adapted for support between a pair of spaced, parallel frame flanges, the combination comprising: a pair of peripherally extending, spaced, parallel sash flanges adapted to be received between said frame flanges, and an openin through one of said sash flanges; a leaf spring element engaging the other sash flange at a point opposite said opening and so positioned that its midpoint is located on the projected axis of said opening; a ball of diameter larger than the diameter of said opening but small enough that it will extend through said opening and beyond the sash flange containing said opening, the thickness of said sash flange being substantially less than one-half the diameter of said ball; said leaf spring being curved away from said other sash flange by such a distance that it engages said ball and holds it against the edges defining said opening.
