WINDOW.

Application filed December-3Q, i920. Serial No. 434,017.'

JOHN CARNEY,

buildings, particularly factories, of modern construction, wherein .a large part of the wall space is devoted to windows for4 purposes .of light and ventilation. The use ofso muchv glass` in a building necessarily makes that side of the building much colder than it would otherwise be, if, instead of use. In such cases my invention is particrularly useful as offering a vacuum window pane unit complete, which may be installed in the regular window sash wherever, and

fective barrier against the transmission of cold from without to the interior of the building, and thereby lessen the additional amount of heat required to offset the cooling of the enlarged window expanse. My invention is also usefulin many other connections as in vehicles, refrigerators, etc., wherever itis desirable to install a window of this kind without making special preparation therefor in the construction of the building or vehicle.

illustrated in the accompanying drawing, in which- Figure 1 is a section throu h one side of an ordinary window sash with a double glass window pane in place; Fig. 2 isthe ront view of a double glass window pane; Fig. 3 is an ed e view of said double glass ig. 4.- is a section through said double glass window pane on line 4 4, Fig. 2; Fig. 5 is a section through an airpump terminal which is not a part of this invention but is shown for purposes of il-A lustration: Fig. 6 is a side view of said airplunp terminal. n

Similar letters refer to similar parts throughout the several views.

My invention is particularly useful iny I 4attain this object by the construction In constructing the double glass window pane the separators a, preferably of glass, are cemented to one plate or sheet of glass b; the-inner frame c, and the packing d, ofi

rubber or the like -are placed between the` plates or sheets of glass b, then the outer' 4 metal frame e, is pressed or soldered 1n place around the double glass window pane. The packing d, isv normally substantially.

larger than the space which it is intended to occupy so that when it is in place it is under compression. thus rendering theenclosure of inner space f, air-tight.

The sharp-pointed air-pump terminal g,

is then inserted at the hole'h, piercingthe vertical strip of packing d, and `forced in be# tween theto of the lowerl or bottom strip of packing an thel inner frame, the packing forcing the terminal into close engagement with the under side of the bottom member of the frame c until the opening y', in the side wall of the terminal g, comes opposite the opening c, in the bottom inner frame c member, Fig. 4, t-hus forming an outlet through which the air`may be 'extracted from thel inner space f, 'through the hollow ,f v

air-pump terminal g, making said space a vacuum or semi-vacuum. When the -airpump terminal .9, is withdrawn the packing d, being resilient, will resume its former position thus closing the opening lc.

The space occupied bythe packing d, may be filled with wax, cement, glue, lead or any other metal or material, and a closable or self-closing opening or valve provided for the extraction of the air from the inner space f. The frames c, and e, may be `of metal or ofany other material.

The vacuum-insulated window pane may then beset in an ordinary sashv with putty as shown in `Fig. 1, or in any other style offrame, opening or sash, by any other method.

A double glass window pane might be made entirely of .glass with a vacuum space incorporated therein during the process of manufacture; or it might be made mainly of glass with a partial frame of metal orl other material which vwould enclose in 'con-v junction with said glass an inner space to y be rendered a vacuum by the extractionof the air therefrom through anopening provided for that purpose and hermetically sealed after the air had been extracted from the inner space. y

An insulated window pane might be made Vacuum container.

of transparent or semi-transparent material enclosing an inner space and having an opening through which the air could be extracted from said inner` space, said opening to be hermetically sealed after the air had been extracted from the inner space thus establishing a vacuum.

I am aware that the use of a vacuum to retard the passage of heat is not new as it has been used in What is known as the I therefore do not claim insulation by means of a vacuum space broadly; but

I claim: 1. A compound window pane-comprising parallel `sheets of glass, means provided 'with an aperture and interposed between and Ico-acting with said sheets to enclose a hollow` space, reslllent seallng means 1nadapted to be perforated by the terminal of an air exhausting means, and -to yield as the terminal is forced into cooperative relation with said aperture to ermit exhaustion of the air from the ho low space,

`and to returnfto original condition to seal the aperture when the terminal is drawn.` y

2.'A compound window pane comprising a plurality of sheets b of transparent material, separators a therefor, an apertured frame c also for the sheets and therewith forming an enclosed space, compressible material d surrounding saidframe and'sealing the joints between it and the panes b and adapted to be punctured by the terminal of an air pump g :for exhausting the air from the space.
