Patented Aug. 1, 1939 UNITED STATES PATENT OFFICE WINDOW CONSTRUCTION Application April 8, 1938, Serial No. 200,918
The invention relates to a window construction of the general type well known in the art employing rubber strips or the like for holding the parts securely in assembled relation, but permitting the ready removal of the glass for replacement or for cleaning the inner faces of the glass panes, in the case of double glazed units. It has for one of its principal objects the provision of an improved construction of the type specified, wherein the rubber strips may be applied and removed very easily Without the exercise of any special skill, but which, at the same time, gives the necessary security against displacement due to vibration or loss of resilience. Further objects are the provision of a cheap, simple construction, applicable to a wide range of use and adaptable to existing forms of devices, in which double panes are carried removably in channel frames. Embodiments of the invention are illustrated in the accompanying drawing, wherein:
Figure 1 is a side elevation of a car window embodying the invention. Fig. 2 is a section on the line II-II of Fig. 1. Fig. 3 is a section through one of .the rubber strips, showing its shape before its application in the window. And Figs. 4 and 5 are sectional views through modifications, Fig. 5 showing another application of the invention to single glazed units.
Referring to Figs. 1 to 3, the demountable glazing unit in this case comprises the panes 6 and 1. The frame therefor is made up of the two releasably interlocked metal angles 8 and 9, following the construction of the Fox and Stroud Patent No. 2,054,856 of September 22, 1936, the angles being held in locked position, as in th'e patented structure, by the wedges I0. When the wedges are removed, the angle 9 can be tilted downward, so as to release the hook engagement at II, thus permitting the separation of the angles and the removal or insertion of the glass panes. The edges of the panes are spaced by the rubber strip I2, and are cushioned in the frame by the usual rubber channel I3.
The glazing frame, as above described, is seated in the sash I4, which is formed with a rabbet to receive it, as shown, such sash being provided forward of the glazing frame with a channel I5, carrying the rubber retaining strip I 6. The frame is cushioned in the sash by the rubber angle I'I. Theflange I8 forming the front side of the channel I5, has its inner edge located, so as to provide a slight amount of clearance with respect to the base of the frame angle 8 to permit insertion of the frame into the sash open- (Cl. 2li-56.4)
ing as defined by the edge of the channel. The terms inner and outer and their variants, as used therein, have reference to locations with respect to the center of the glass panes.
'I'he frame of the glazing unit is held in posi- 5 tion by means of the rubber strip I6, which before insertion, has the cross section indicated in Fig.
3, so that when forced into position, the lip i9 will bear strongly upon the face of the frame. The strip, as shown, is provided with a lip 2U 10 which ts over and covers the flange I8, the purpose being to give the construction a better appearance from the front and to add somewhat to its security. The strip is also preferably provided with a longitudinal groove 2| for interlockl5 ing with the ends of the wedges 9 which project forward of the face of the frame, as shown, so as to form a locking rib on the frame which adds materially to the security with which the rubber strip is held in its channel I5 in the sash. The 20 .thickness of the lip 22 of the strip I6 is such that it must be compressed in forcing it into its channel, so that considerable frictional resistance is provided tending to prevent the accidental displacement of the strip, after it is forced into 25 position. The use of the rib on the frame augments this resistance to accidental displacement, rendering the anchoring of the strip very secure, even after the rubber has lost some of its resistance. While the use of the groove 2| in the rub- 30 ber is desirable, it is not essential, as the rib will, in any case, perform its locking function by seating itself in the rubber due to the pressure.
The rubber may be applied in one strip extending clear around the Window, but is prefer- 35 ably used in two sections in a window, such as that of Fig. 1, the joints being shown at 23, 23. The frame members 8 and 9 and the wedges I0, are also used in sections, the window shown requiring a section for each straight side and one 40 for each curved corner. It will be apparent that the assembly consisting of the glass panes and the metal frame may be readily inserted into the sash and secured by the rubber strips, and on removal of thestrips, the frame can be re- 45 moved from the sash and opened up for replacement or cleaning of the glass by removing the wedges.
Fig. 4 illustrates a modification, in so far as the frame construction and sash construction are concerned, the rubber holding strips being the same in shape and function, as thoss heretofore described. As in the first construction, the sash 24 is provided with a rabbet for carrying the frame and has a channel I5 forward of the frame 65 and outward thereof for receiving the rubber strip I6. The frame which carries the glas sbeet.is a channel made up of the oppositely facing angles 25 and 26, whose base iianges are securediniixed rotation by a layer 21 of self hardening material, such as sealing wax, sulphur, putty or low fusing metal. In order to provide the locking rib for the rubber strip I6, the base ilange 2l of the angle 25 is extended forward past the face of the'frame, as shown at 29, so that it performs the function of the end of the wedge Il in the oonstruction of Figs. 1 and 2.
Fig. 5 illustrates a modication, in which the glazing unit comprises the single glass pane 3|.A
The frame 3| is of rubber which has a recess or rabbet in which the edge of the pane ts. The edge of the frame is extended tothe right of the plane of the face of the pane 30, thus providing the rib 32 which interlocks with the rubber holding strip 33. This strip diiIers primarily from the strip I6 heretofore described, in that it lacks the lip 20. The frame 3| nts intoa rabbet in the sash 34, while the rubber strip 33 lies in a channel 35 formed in the sash and located outward of the frame 3| and in front of the plane of the face of the pane 30. The strip 33 functions to hold the frame 3| in the sash in the same manner as the Broadly. -it is the xed portion of the wall immediately strip I1, the only diierencebeingthat then-rig Ilengagesandholdsbotbthepaneand its frame,\ whilethestrip iiengagesandholdsonlytbe :trame of the unit.
