9 Claims.

The invention relates to window constructions of the type employing rubber strips under compression for holding the glazing unit removably in position in the sash or frame. It has for its 5 principal objects the provision of an improved construction of the type specified, which will permit the more ready and convenient application and removal of the rubber strips. Heretofore, in the use of rubber holding strips, it has been necessary to force a portion of the cross section of the holding strip through a throat in the frame, and in order to make the construction secure, the amount of deformation of the strip in order to get it positioned has been such that much effort and time is required for the assembly, particularly on the part of an unskilled worker. The present invention is designed to obviate this objection by providing a structure in which the assembly may be performed in two steps neither of which presents any difficulty, a main holding strip being first applied and then tightened by a secondary strip which deforms the first strip so as to secure the necessary holding effect with respect to the sash and a suitable sealing pressure by one of the strips upon the glass. Certain embodiments of the invention are illustrated in the accompanying drawing, wherein:

Figure 1 is a front elevation of a car window embodying the invention. Fig. 2 is a section on the line IIII of Fig. 1. And Figs. 3 to 7 are sections similar to Fig. 2, but showing modifications.

Referring to Figs. 1 and 2, the numeral 8 designates the sash or frame, and 9 is the glazing unit in the form of a sheetor plate of window glass. The portion of the sash which carries the edges of the plate 9 is in the form of a channel having a back flange I which backs up the edge of the glass plate around its periphery. H is the front flange of the channel which is substantially shorter than the flange l0 so as to provide clearance for the movement ofthe glass plate into and out of position. A strip I2 of rubber of angular cross section serves to cushion the edge of the plate in the sash.

The glass plate is secured in position in the sash by means of the rubber holding strip l3 which fits down into the channel with its base portion 14 under a slight amount of compression. Extending longitudinally of the strip is a slot l5, which is closed or nearly so when the strip is put into position. After the strip is positioned, a second strip I6 is forced down into the slot spreading the strip l3, so that it is yieldingly held in the channel on one side and against the edge of the plate 9 on the other side, thus securely locking the parts in the assembled relation shown. The strip I6 is preferably of a material harder than the strip l3, so that the most of the deformation which occurs, due to the assembly, occurs in the strip I3. Hard rubber is a suitable material for this strip, and a relatively hard strip of this character is more easily forced into position in a slot than a strip of soft rubber. Other materials which might be substituted for the hard rubber are fiber or one of the synthetic resins, such as vinyl acetal or Bakelite. The strip 13 may be made all in one piece, but is preferably made in two pieces in a window of the type shown in Fig. 1, the two pieces meeting along the lines i1, i1. Similarly, the strip l6 may be made all in one piece, but is preferably made in two pieces corresponding in longitudinal dimensions to the sec-' tions of the member I3.

In making the assembly, the glass plate 9 is first positioned in its rabbet in the frame 8 and the strips I 3 are pushed into position. There is no difliculty about this operation, since the amount of deformation in order to get the members l3 into position, is relatively slight. After this assembly has been made, the wedge strips l6 are pushed into position, as indicated in Fig. 2. This part of the assembly is also relatively easy, as all that is necessary is to start the wedge portion into the slot l at one end of such strip and then progressively push it in, the wedge shape of the member l6 facilitating this assembly. When the parts are assembled, the member I3 is placed under compression, such that it is very securely held in place and exerts substantial pressure against the plates 9 in opposition to the backing up flange III. In disassembling the parts, it is only necessary to start the removal of one of the strips H5 at the end, after which it is very easily pulled out, as is also the strip 13 after the wedge strip I6 is removed.

Fig. 3 illustrates a modification, in which the plate 9 is held in the sash 8 by means of the two strip members l8 and. I9. These members are both of soft rubber, and the method of assembly follows that heretofore described, the main strip l8 being first positioned in the channel with its base 29 under a slight degree of compression, after which the wedge member I9 is pushed down into position, being locked by friction and by the interlocking shoulders at 2|. In this case, the wedge member I9 is of soft rubber instead of being of hard material, since it is desirable to make good sealing contact with the glass.

In the modification of Fig. 4, the pane 9 is held in its sash III by means of the two strips 22 and 23, 22 being the main strip and 23 the wedge member. A lip 24 is preferably provided for covering the strip 23 when the parts are in assembled relation. In this case, as in the Fig. 3 construction, the wedge member 23 is preferably of soft rubber the same as the strip 22. After the strip 22 is applied, the lip 24 is pulled back and the strip 23 of circular cross section is wedged into the recess, thus deforming the member 22, so that it is held firmly in its channel and a sealing contact is secured between the member 23 and the face of the pane 9.

In the construction of Fig. 5, the pane 9 is held in its sash 8 by means similar to those shown in Fig. 2 except that the 'wedge member 25, which fits into the slot 26 in the rubber strip 21, is of circular cross section instead of being of triangular cross section. The strip 25 is of a material which is relatively harder than the strip 21, and in this case, a wire or hard woven cord may be used in place of the materials referred to in connection with Figs. 1 and 2 if desired.

Fig. 6 discloses a construction in which the pane 29 is held in its sash 29 by means of the spring clips 30 acting in conjunction with the rubber strips 3i. After the spring clips are positioned, the rubber members 3| are wedged into position as shown, thus forcing the arms of the spring clips tightly against the bottom of the channel in the frame and against the face of the plate 28, the strip 3| functioning in the same manner as heretofore pointed out in connection with the strip it of Fig. 2. The strip It is preferably so proportioned that when positioned, as indicated in Fig. 6, it completely covers the spring clips and bears at its edges against the flange 32 and against the face of the glass plate 23.

Fig. 7 illustrates another modification showing the application of the invention in connection with double glazing and wherein 33, 33 are the glass panes and 34 is the frame or sash in which the edges are seated with the spacer 33 therebetween. The main holding strips are the rubber members 31, 31 which flt down into the frame as shown. The lips 33 of the strips 31 are caused to press strongly against the outer faces of the panes 33 by the use of wedge members 39 which are preferably of hard rubber and flt into grooves in the members 31 and bear at their lower sides against the flanges ll of the channel. The wedges 39 are inserted after the rubber strips 38 are positioned and serve to deform the members 39, so that the necessary sealing pressure is applied to the faces of the glass panes.
