MULTIPLE PANE WINDOW UNITS David Shinefeld, Philadelphia, Pa., assign'or to Multipane, Inc., Philadelphia, Pa., a corporation of Pennsyivania Application August 24, 1955, Serial No. 530,254
3 Claims. (Cl. 2056.5)v
This invention relates to multiple pane window units, that is, to heat insulating window units composed of a plurality of sheets of glass, separated from each other by suitable spacers at their edges, and Yprovided with means for removing the moisture from the air in the spaces between the glass sheets, whereby there will be no clouding on the internal surfaces of the glass through condensation, fungus growth, or the like, which are induced by the j itedV tts Patent the means for sealing the window units at their edges to prevent improper ingress and egress of air into and from the spaces between the glass sheets.
This invention further relates to improved means for permitting the breathing .which is necessary to equalize the pressures on the glasssheets causedby the differences in atmospheric pressure when the sealed window units are transported through regions of diierent atmospheric pressures. The principal object of the present invention is to provide, in a multiple panewindow unit; improved devices for" spacing the sheets of glass at their edges, w hich'spacing devices are so constructed and arranged as to properly support the edge portions'of the glass sheets and also to provide containers for the desiccant used for removing the natural moisture in the entrapped air in the spaces provided between the glass sheets.
A further object of the invention's to provide in a structure of the character aforesaid, improved means for sealing the units at the edges thereof which will prevent leakage of air either inwardly or outwardly.
A further object ofthe invention is to provide improved breathing means, so constructed and arranged as to permit the ingress and egress of air whenever it becomes necessary to transport the sealed units through regions of different atmospheric pressures, which would otherwise cause the units to be broken, even though the pressure diterences may be relatively small, as under such conditions the pressure over the total area of the glass sheets is often suiiicient -to cause breakage.
The nature and characteristic features of the present in'- vention will be more readily understood from thefollowing description, taken in connection with the accompanytransported through regions of different atmospheric pressures which might cause the sheets of glass to be broken by the overall pressures on the same; and
Fig. 4 is a transverse section taken approximately on the line 4--4 of Fig. 3. Y
It should, of course, be understood that the description and drawing herein are illustrative merely, and that various modifications and changes may be made in the structure disclosed without departing from the spirit of the invention. f
The multiple pane window units made in accordance with the present invention comprise a plurality of sheets of glass 10 maintained in spaced relationship by means of suitable spacers 11, hereinafter more specifically described.
When more than two sheets of glass are employed, the intermediate sheets may be and usually are thinner than the external sheets.
The spacers 11 are preferably made of sheet metal, pressed and formed in a peculiar shape in cross-section as shown more particularly in Fig. 2 of the drawing. These spacers 11 are made initially in suitable lengths and cut angularly at "the ends of the pieces to form miter joints at the corners as shown more particularly at 12 in Fig. 1 of the drawing.
' Each of the spacer members 11 is of an approximately rectangular shape in cross-section having its outside wall l13 ajtand its inner wall comprising abuttinginternal lips of the edge portions of the glass sheets abut and are thus' supported. t
The sidewalls of the spacers, toward the outside walls 13, are indented as at 17 to provide relatively small spaces between the side surfaces of the portions 17 of the sidewalls of the spacers and the edge portions of the glass sheets, for a purposel to bepresently set forth. Y
After the unit is assembled, with the desired number of glass sheets separated by the spacers arranged as above described, the edge portions are sealed by a suitable initially liquetiable plasticr18, which will provide an effective air and moisture seal, not only by coating the external walls of the spacers and the edges of the glass sheets, but
t also by passing into the spaces between the inset portions 17 of the sidewalls of the spacers and the edge portions of the glass sheets, by capillary action while the sealing material is still in a suiciently liquid state to enable it to do so. Any suitable plastic sealer may be used, but one which has been found to be satisfactory comprises a rubber compound having a thiokol base.
The hollow interiors of the spacers 11 provide suitable containers for placing therein a suitable desiccant 30 having moisture absorbing properties, and the slit 15 between the abutting lip portions 14 of each of the spacers 11 provides a sufficiently open means of communication from the sealed spaces between the sheets of glass to the hollow interiors of the spacers within which the desiccant 30 is placed.
When it is necessary to `ship the units through or to areas of different atmospheric pressure such, for example, as when theunit must be shipped from the Eastern seaboard to the Western seaboard, in passing through the mountainous regions, the atmospheric pressure differences are sometimes suicient to cause the air sealed Within the unit to expand and thereby break the glass. This phenomenonhas, of course been noted, and various means have heretofore been provided to overcome the same, but most of such devices used or suggested have been unnecessarily complicated and, in some instances, not entirely practical.
For this purpose there is provided, in connection with the present invention, a plurality of U-shaped tubes 20 of small diameter, the end portions-,21 of which. eachA serve to permit the pressure Within the spaces between the'glass sheets to be equalized lwith eachother and with lthe external atmosphere whenever the unit is transported through or to a place having` a different atmospheric pressure. i When the unit arrives at the place where it is to be used, the pipe 22, whichV extends tothe external atmosphere from one of the spacing devices, may be closed or sealedv off in any suitable manner to prevent any further breathing at the place of use. y
It should be understood that the foregoing pressure equalizer is not required when the unit is to beA installed at or near the place of its initial assembly.
By the foregoing there is provided a novel and inexpensive multiple pane window unit which may be readily and easily assembled, which is provided with means whereby any moisture in the Vair in the spaces between the r sheets of glass will be taken up by the desiccantvcontained within the interiors of the spacers provided at the edges of the sheets, and in which a simple and eifective breathing device may be incorporated if desired.
In` some instances it will be advisable to utilize the U- shaped tubes 20 without the externally extendingr tube 22. With such an arrangement, in the event of large temperature diterentials on the inner and Vouter faces of the inultiple pane. window units, any inequalities inthe pressure ih the several spaces between the glass sheets caused by such temperature differences will be equalized bya Vsmall amount of the air being permitted to flow fromone space to another through the tubes 20. Such an arrangement will be foundv to be desirablel in regionssubject to very low winter temperatures. A
-I claim: v 1. A multiple pane window unit comprisingr a plurality of sheets of glass, means for spacing said glass. sheets and for sealing the spaces between said glass sheets, said spacing and sealing means consisting of members extending adjacent and between the edge portions of the glass sheets and comprising strips of sheet metal longitudinally bent and formed to provide Van outer wall, and a wall on each side the inner portionsof which side walls provide bearing surfaces for the edge portions of the glass sheets and the outer portions of which side walls are inset to provide narrow spaces between said outer portions of the side walls and the edge portions of the glass sheets, and initially liqueable plastic material covering the outer walls of the spacing members and the edges of the glass, and extending into the spaces between the inset portions of the side walls of the spacer members and the surfaces of the edgey portions of the glass sheets.
