The invention relates to a double glazing construction. It has for one of its objects the provision of a double pane mounting which can be used to advantage without the requirement for a sash which is thicker than the ordinary standard sash employed for windows using a single glass. A further object is the provision of a mounting or frame for the double pane of light spring construction for insuring yielding pressure upon the seal between the edges of the sheets, but which has at the same time a greater degree of strength and rigidity than the spring frame mounting heretofore proposed. A still further object is the provision of a mounting permitting the sheets to move freely at their edges as they bow in and out under varying changes in atmospheric pressure.
Briefly stated this result is secured by the use of a U-shaped frame of light spring metal, which grips the glass sheets inward a slight distance from their extreme edges and is provided with a fin or rib that is seated in the window sash and secured by glazing material, such as putty. This permits the use of ordinary sash regardless of the thickness of the double pane and gives a unit in which the edges of the glass sheets are adequately protected against injury in handling and shipment. Certain embodiments of the invention are illustrated in the accompanying drawing, wherein:
Figure 1 is a front elevation on a small scale of the clamping frame for the glass sheets. Fig. 2 is a section on an enlarged scale through the edge of the unit and the sash or casing in which it is mounted. Fig. 3 is a section through the clamping frame before such frame is applied to the glass sheets. Fig. 4 is a section through a modification. Fig. 5 is a section through the clamping frame employed in the construction of Fig. 4. And Fig. 6 is a section through another modification.
Referring to the drawing, l is a sash or frame provided with a shoulder 2 and a groove 3 for receiving the edge of the unit which is to be mounted in the tfame. The unit as shown comprises a pair of glass sheets 4, 4 provided with spacing and sealing means around the edges of the sheets, the spacing means preferably being in the form of the rubber strips 5 which are space between the glass sheets is filled with dehydrated air and this air is maintained in dry condition due to the use of the sealing members 5. Nitrogen or some other inert gas may be sub- 55 stituted for the dry air.
In service, the
Extending around the edges of the glass sheets is the rectangular frame shown in Fig. 1, such frame being made up of the members 6, 8, 3 shown in cross section in Figs. 2 and 3. The members 6 are preferably of relatively light spring metal ,U-shaped in cross section comprising the flanges I, I, the base 8 and the rib 9 projecting at right angles to the base. Before the frame or clamping member is applied to the glass, the flanges I, I are inclined toward each 10 other, as indicated in Fig. 3, but after the member is applied to the glass sheets, the flanges are brought more nearly into parallelism, so that they apply yielding pressure to the glass sheets and to the spacer 5. The pressure thus applied 15 improves the seal between the spacer and the glass sheets and serves to hold the assembly securely together. After the four members 6 are applied to the unit, they are soldered together along the lines "I (Fig. l) thus insuring against 20 displacement with respect to the glass sheet. In securing the sections of the frame together, a. solder is employed having a low melting point in order to avoid injury to the spacing members 5 during the soldering operation. The rib 9 which 25 projects from the base of the members 6 serves as a stiflener and also provides a means for mounting the unit in the groove 3. This mounting is preferably arranged, as indicated in Fig. 2, with a holding material ll, such as putty, filling 30 the groove and surrounding the rib on both sides, thus providing a seal between the sash and the glazing unit. The use of the rib permits the unit to be mounted in a sash of ordinary thickness, such as would not be the case if the 5 edge of the relatively thick glazing unit were seated in the groove 3.
Figs. 4 and 5 illustrate a modification in which a different form of spacer and a different form of clamping or frame member are employed. 40 The spacers in this case consist of metal strips I2 which are U-shaped in cross section. The metal is relatively light and thin and is faced with strips l3, l3 of sealing material of soft rubber or the like. The frame members M are 45 formed from spring material bent into the shape shown in Fig. 5 and having the inclined flanges I5, l5 and the rib member IS, the latter performing the function of the rib 9 of the Fig. 3 construction. The provision of the rib I6 of the form shown gives additional resiliency to the members and may be cheaply formed by a rolling operation. The mounting of the unit in the sash I is the same as in the construction of Figs. 2 and 3.
It will be noted that the spring U frame is formed so that it grips the glass sheets inward from their extreme edges, thus leaving such edges free to move in and out inside the frame. This is important under varying atmospheric pressures as the danger of breaking the glass is minimized as compared with mountings in which the edges are clamped or held rigidly so that a relatively heavy strain is imposed upon the glass along the edge of the frame when the glass bulges in or out due to atmospheric pressure changes. This freedom of movement of the sheet edges is also promoted by the type of spacers shown. The round type of spacer shown in Fig. 1 permits the sheet edges to move in freely, whereas a spacer of rectangular cross section would tend to prevent it. Similarly the spring U spacer of Fig. 3 also permits the same freedom of movement about the yielding upper portions of the flanges of the U section.
Fig. 6 illustrates a further modification in which the clearance at the base of the frame member H is provided by beveling off the edges of the glass sheets as indicated at l8 so that such edges are free to move in and out,as in the other constructions. The flanges of the frame member are inclined toward each other before the application of the frame to the glass so that the edges of the glass sheets and the seal (which is similar to that of Fig. 4) are maintained under spring pressure.
