Patent-ed Sept. 28, 1937 UNITED STATES PATENT OFFICE DOUBLE WINDOW CONSTRUCTION Application september s, 1935, serial No. 39,424l 3 claims. (ci. en -56.5)

The invention relates to a double glazed window and has for its objects the provision of an improved mountingfor the two sheets of glass,

, which is relatively cheap and simple; which is 5 secure and permanent; which provides for an adequate seal; and ,which can be used with glass and spacers which have varying thickness.v Certain embodiments of the invention are illus-- trated in the accompanying drawing, wherein:

Figure 1 is a section through one edge of the unit as assembled preliminary to clamping the two membersl constituting the channel together. Fig. 2 is a section similar to that of Fig. 1, but with the parts of the channel clamped together and with the unit mounted in a car frame. And Fig. 3 is a section similar to that of Fig. 1, but With the unit mounted in a Wood sash.

Referring to Figs. 1 and 2, 3 and 4 are glass sheets and 5 is a spacer preferably of rubber or other resilient material capable of forming a seal and lying between the sheets at the margins thereof. The frame which carries the sheets is of channel form and comprises the outside-member 6 and the inside member 1. There are four of each of these members to correspond to the four sides of the window and after assembly, they vare secured together at the corners by welding, soldering or by interlocking mechanical means well known in the art. v

'Ihe member 6 is of L cross section and comprises a iiange 8 in opposition to the face of the sheet 3 and a base 9 extending across the edges of the two sheets with its end I projecting past the face ofthe sheet 4, as illustrated. The member 1 is also of L shape having'a flange II in opposition to the face of the'sheet 4 and a base I2 of hook shape formed, as indicated in Fig. 1, the opposing faces of the parts III and II being preferably serrated to guard against slipping after the part is bent to clamping position. The members are preferably of extruded metal, such as aluminum or brass, and are relatively free from temper so that the part 1 will remain in any position to which it is bent.

Packing and sealing material I3 and I4 is interposed between the outer faces of the glass sheets and the iianges 8 and II. After the parts are positioned, as indicated in Fig. 1, pressure is applied to cause a movement of approach between the anges 8 and II, thus compressing the spacer Aand the sealing strips I3. andl, after which the ange I2 is bent by a suitable press into clamping engagement with the end I0 of the ange 9. This completes the operation of assembling the unit, aside from the securing prising an of the four members 6 and the four members 1. together at the corners of the Windows, as heretofore referred to.

The unit may no w be mounted in a. sash or frame, either of4 wood or metal Yin any suitable In Fig. 2 the mounting is in a car frame, I4 and l5 being the side plates of the frame and I6 being clamping strips secured by the screws I1. Packing means I8 of rubber or the like is preferably used, as shown.

Fig. 3 illustrates the mounting of the unit in a wood sash I9, the putty 20 and nail 2| extending through suitable perforations in the meinbers 6 and 1 serving to secure the unit in place. When replacements are required, the unit is removed from its frame, and the mounting is removed by opening the ange I2 with a suitable manent and permits of a substantial degree of adjustment to accommodate glass and spacers n of varying thickness.

What I claim is'. 1. In a double window construction, a pair of spaced glass sheets with spacing and sealing means between theirmargins, a channel in. which u ing its flange in opposition to the outer face of one of theglass sheets, and a second member having a flange in opposition to the outer face of the other glass sheet and also having a hookshaped base at right angles to the flange which ts around and clampingly engages the edge of the base of the L-shaped member, said members having means integral therewith to prevent lateral displacement of the members.

2. In a double window construction, a pair of spaced glass sheets with spacing and sealing means between their margins, a channel in which the edges of the glass sheets are mounted com- L-shaped member having its base extending across the edges of the sheets and projecting past the outer face of one sheet and having its flange in opposition to the outer face of one of the glass sheets, and a second member having a iiange in oppos'tion to the outer face of the other glass sheet and also having a hookshaped base at-right angles to the flange which fits Yaround and clampingly engages the edge of the base of the L-shaped member, the interengaging surfaces of the two members being provided with serrations. Y

3. In a double window construction,v a pair tool. The mounting is relatively cheap and'perv of spaced glass sheets with spacing and sealing means between their margins, a. channel in which the edges of the glass sheets are mounted comprising an L-shaped member having its base extending across the edges of the sheets and Projecting past the outer` face-of one sheet and having its 11a-nge in opposition to the outer face of one of the glass sheets, and a second member free from temper having a ange in opposition to the outer face of the. other glass sheet and also having a base ofV U shape, whose sides lie on opposite sides of the base of the L-shaped member and clampgly engage the same, both engaging surfaces being provided with meansintegral therewith for insuring the clamping engagement.
