UNITED STATES PATENT OFFICE 2,015,808 DOUBLE WI NDOW CONSTRUCTION Robert A. Miller and Fredericlr Gelstharp, Tarentum, Pa., assignors to Pittsburgh Plate Glass Company, a corporation of Pennsylvania Application January 15, 1935, Serial No. 1,878 Claims. (01. 20-565) The invention relates to a double window construction involving the use of a double pane unit with the space between the panes hermetically sealed and filled with dry air or nitrogen to avoid ,ment is designed to take care of this condition.
The invention has for its principal object the provision of an improved construction for reducing the differential between atmospheric pressure and the pressure which exists between the glass sheets of the glazing unit. Briefly stated, it involves the use of collapsible containers located in the frame carrying the glazing unit and connected with the space between the glass sheets, such containers being in partly collapsed condition when the unit is glazed at elevations not greatly above sea level. A further object of the invention is the provision of an improved frame or mounting which clamps the glass without the use of visible securing means, such as screws or bolts. Certain embodiments of the invention are illustrated in the accompanying drawings, wherein:
Figure 1 is a front view of the glazing unit and its mounting. Fig. 2 is a section on the line II-1I of Fig. 1. Fig. 3 is a section on the line IIIIII of Fig. 2. And Figs. 4 and 5 are sections through A modifications. w
Referring to the drawings, l is a part of the structural work of the car which carries the window mounting, and 2 is the window frame or sash which is secured to the structural member I by' means of the screws 3. The member 2 is provided with grooves or seats for the glazing unit which consists of the sheets land 5 with the space therebetween sealed by means of the U-shaped members 6 of soft material, such as rubber. The margins of the sheets are secured in the grooves by means of the clamping plates I, I held by the screws 8. Mounted on the structural member I is a frame member 8a so formed that when connected with the members I and 2, a cavity 9 is provided which extends around the periphery of the window. This member and the member 2 are preferably made in four sections, one for each side of the window and the members 8a are held in position by means of thescrews 9a.
Seated in the cavity 9 on each side of the window is a tube l0 preferably of thin metal or rubber, which may be readily collapsed and expanded when varying air pressures are applied to the interior. This tube is practically coextensive in length with the cavity in which .it is mounted and is connected at its end with the space H between the glass sheets by means of the tube l2.
When the construction is installed, the pressure I between the glass sheets is adjusted so that they tube is in a partially collapsed condition as illustrated in the drawings. When the car in which the window is mounted, is moved to a relatively high elevation as in passing over mountains, at 10 which time atmospheric pressure is reduced tend-- ing to cause the glass sheets to bulge outward, this excess pressure is released to a large extent by the discharge from the space H into the tubes which thus expand correspondingly. The danger of fracturing the glass due to these changes is thus reduced to a minimum. The space 9 required for the tubes is not great so that the frame construction may be installed without any noticeable change in appearance from the interior of the F car and without any loss of space, which is detrimental. Access to the space carrying the tube is readily secured by the removal of the member to.
frame, in which the glasses 4 and 5 are mounted,
, is made up of a pair of plates l3 and I4 connected by the tie plate I5 that has a hook connection with the plate It, as indicated at It. This permits the plate l4 to be tilted so as to secure a 30 clamping action between the flanges I60 and IT.
This clamping action is provided by means of the wedge l8 which fits between the lower edges of the plates I 3 and H, such wedge being held releasably 6 in position by means of the removable pins IS. The seal between the glass sheets is provided in' this case by means of a rectangular frame lying between the U-shaped sealing members 6.
' A collapsible tube 2| is employed in this construction corresponding to that described'in connection with Figs. 1 to 3, and such tube has its end connected to the space between the glass sheets by means of'the tube 22, which extends through the frame 20. The closure above the cavity 23 is provided in this case by means of the member 24 45 Fig. 4 illustrates a modification in which the 25 the tie plate in order to secure the necessary clamping action of the flanges 28 and 29 upon the glass sheets. A wedge 3| is employed between the lower ends of the plates 26 and 21 corresponding in function to the wedge l8 of the Fig. 4 construction, and this wedge ,is secured releasably in position by means of the pins 32. The member 33 surrounds the cavity 34 carrying the collapsible tube 35 on three sides, and is held in place by means of the screws 36. The constructions of Figs. 4 and 5 are advantageous because of their simplicity and because the clamping action of the flanges of the mounting upon the edges of the glass sheets is secured without the necessity of using the screws such as the screws 8 in the Fig. 2 construction.
It will be understood that in the constructions of Figs. 4 and 5, the structure for each side of the window is the same as that illustrated, there being four separate plates l 3 and I4 for each window of the Fig. 4 construction and four separate plates 26 and 21 for each window of the Fig. 5 construction. In assembling, all four sets of plates are applied to the glass sheets, after which the wedges are positioned as shown. After the meeting ends of the plates have been suitably secured together at the corners of the window by solder or screws, the unit as thus assembled is fitted into the car body as shown and the members 24 (Fig. 4) and 33 (Fig.5) are secured in place.

I

5. In combination in a double window construction, a frame comprising a pair of parallel plates connected intermediate their ends with a tie plate which acts as a seat for the glazing unit and which has a pivotal hook connection with one of the plates to permit it to be tilted relative to the other plate, a glazing unit consisting of a pair of glass sheets spaced apart with sealing means between their margins having such margins seated on the tie plate between the inner edges of the parallel plates, a wedge between the outer edges of the parallel plates, and releasable means 40
