AIR CHANGE MEANS FOR WINDOW GLASS INSULATION SYSTEMS Filed March 20, 1936 Patented May 17, 1938 I antral AIR CHANGE MEANS FOR WINDOW GLASS INSULATION SYSTEMS Samuel A. Stoneback, Philadelphia, Pa.
Application March 20, 1936, Serial No. .77! In Canada January 24, 1936 SClailns.
My invention relates to a new and useful air change means for a window glass insulation system and is particularly adapted for use in connection with my invention set forth in Patent No. 2,042,077 which was co-pending application, Serial No. 741,891, filed August 29, 1934, andallowed October 31, 1935.
One of the objects of the present invention is to .provide a structure consisting of spaced parallel panes of glass in doors, windows and the like to form a dead air space which will act as insulation against a temperature on the outside of a building different from the temperature on the inside of the building and having means 15 whereby the air within the space may be removed and displaced by other air.
Another object of this invention is to provide means whereby any humid air within the dead air space may be removed to eliminate the humidity and to replace such air with dehydrated air and thereby prevent the formation of moisture on the glass, generally known as sweating, due to the differences in temperatures on opposite sides of the panes of glass.
Another object of the invention is to provide openings leading from and to the dead air space whereby an air pumpmay be used to ,force air through one of the openings and drive out the air within the space through the other opening.
Another object of the invention is to form recesses in the sash and holes in the moulding aligning with the recesses whereby openings or air passageways are produced which are closed except during the air changing operations.
a A further object of my invention is to produce the recesses or inner ends of the openings of unique formation to assist in distributing the air within the dead air space.
A still further object of my invention is to provide a valve controlled opening leading to the dead air space.
With the above and other objects in view, this invention consists of the details of construction and combination of elements as well as particular arrangements of parts hereinafter set forth and then specifically designated by the claims.
In order that those skilled in the art to which this invention appertains may understand how to make and use the same, I will describe its construction in detail, referring by numerals to the accompanying drawing forming a part of this application, in which:
. Fig. l is a view in elevation of a window emgg bodying my invention.
(Cl. ZIP-58.5)
Fig. 2 is an enlarged vertical sectional view of the two sashes of the window.
Fig. 3 is a section on the line H of Fig. 4. Fig. 4 is an enlarged fragmentary face view of one sash like the illustration in Fig. l. Fig. 5 is a fragmentary sectional view, the same as shown in Fig. 2 illustratingv the use of a hand pump for changing the air.
Fig. 6 is a longitudinal sectional view of one sash showing a modification of the invention, and 10 Fig. 7 is an enlarged fragmentary section similar to the illustration in Fig. 6 to show certain details of construction.
In carrying out my invention as herein embodied ill represents a frame of door, window or the like, which for purposes of illustration is shown as a sash of a window. This frame III has the usual or primary pane of glass I! mounted therein which must beair tight.
An additional or secondary pane of glass I2 is placed directly against theface of the frame II n so as to be disposed across the light opening and in spaced parallel relation to the primary pane of glass I I. Where the invention is'used in connection with double hung or sliding window sashes. said additional or secondary pane of glass i2 is placed on the outside face of the upper sash and on the inside face of the lower sash. The additional or secondary pane of glass I2 is held in place by suitable molding II with a plastic compound H in grooves or recesses to provide tight joints. The construction thus far referred to is fully described in my co-pending application above mentioned. 1
By this arrangement of the two panes of glass,
a dead air space I5 is formed that efllciently insulates one side of the frame from the other and prevents the passage of heat or cold, as the case may be, from the outside to the inside of a building.
In the top and bottom rails of the frame II are formed recesses or notches l6 under the .mouldings l3 and holes I! are made through said moulding in registration or alignment with the recesses and beyond the edges of the glass I! thus providing openings or air passageways from the outside of the frame to the dead air space. Preferably these openings or air passageways are diagonally opposite each other so that air forced into the'dead air space through'one opening will flow over a larger area directly toward the other opening than if the openings are in a perpendicular line.
To assist in spreading the air stream, the recesses or notches I. are formed so that their gg the holes I! communicate with them and preferably the inclination of one wall of each recess or notch is greater than'the other wall as indicated in Figs. 1 and 4.
The holes I! have threaded plugs I8 screwed into them for closing the openings or air passageways and upon their removal the nozzle of an air pump I9can be temporarily mounted in one 10 of the openings and air forced into the deadair space which will drive the air in said space out through the other opening thereby replacing such air.
If desirable a tube or elbow can be fitted 15 in each opening or air passageway and the outer end of such tube is normally closed by a threaded plug' 2| screwed into said outer end thereof. Upon removal of a plug the air pump 19 can be attached as previously described. For purposes 20 of illustration I have shown one of the tubes 20 with a spring actuated check valve 22 but it will be obvious that both tubes in one assembly can be used with or without valves.
It has been discovered that under some condi- 25 tions, as during damp or rainy weather, when an installation of the insulation system is made, the
dead air space contains humid air and due to changes of temperature the moisture will accumulate on the glass. While this is not especially detrimental it is undesirable and annoying. By removing the closure plugs and connecting an air pump or suction device to one of the air passageways the air within the dead air space can be removed and replaced by other or fresh air which has been dehydrated naturally or caused to flow through a suitable dehydrator, such as a tube containing silica gel. When this has been done very little condensate can form under the most adverse conditions and the chance of frosting is reduced to a minimum.
of course I do not wish to be limited to the exact details of construction herein shown and described, asthese maybe varied within the scope of the appended claims without departing from the spirit of my invention.
Having thus fully described my invention what I claim as new and useful is:-
walls diverge inwardly or from the points where 1. A frame having a primary pane of glass mounted therein with air tight joints, a secondary pane of glass placed against one face of said frame so as to be in spaced parallel relation to the primary pane of glass to form a dead air space, said frame having recesses therein back of the secondary pane of glass and extending beyond the edges of said secondary pane of glass, means including moulding to hold the secondary pane of glass in place and form air tight joints, the moulding having holes therethrough communicating with the recesses and adapted to receive air evacuating means for replacing the air in the dead air space, and screw plugs removably mounted in the holes to normally close the air passageways.
2. A frame having a primary pane of glass mounted therein with air tight joints, a secondary pane of glass placed against one face of the frame to provide a dead air space, moulding to hold the secondary pane of glass in position with. air tight joints, said frame having recesses in its top and bottom rails diagonally opposite each other back of the secondary pane of glass and communicating with holes through the moulding beyond the edges of the secondary pane of glass, the walls of said recesses diverging inwardly and the walls toward the vertical center of the frame having the greatest inclination, and closures removably mounted in the holes.
3. A frame having a primary pane of glass therein, a secondary pane of glass placed against one face of said frame in spaced parallel relation to the primary pane to form a dead air space, means to secure the secondary pane in place, a plastic composition for sealing the joints between the edges of said secondary pane'and the frame, a tube set into the frame at the upper part of the dead air space and forming a communication between the exterior and interior of said dead air space, and another tube set into the frame at the lower part of the dead air space and also forming a communication between the exterior and interior of said dead air space, said tubes permitting the removal of air from and the injection of fresh dry air into said dead air space.
