7 Claims.

This invention has to do with vertically slidable sash of the type used. in the windows of railway cars, busses and other vehicles, and is particularly concerned with the way in which the bottom rail sealing strip is held in place.

The usual practice has been to provide a channel with inturned side flanges on the lower edge of the bottom rail and fit into it a rubber strip with undercut side grooves, relying upon the engagement of the flanges within the grooves to keep the strip in position. The trouble with this sort of mounting has been that at the ends of the bottom rail where the rubber strip projects into the guides there is a pull on the ends of the strip when raising the sash in closely fitting guides, which pull frequently is enough to start one of the ends of the strip out of the channel, and when this once begins the strip will peel out with but very little resistance. This difliculty 0 is particularly pronounced where the sash is of the type in which a rubber or felt strip is mounted in or on the side rail for engagement with the guide, in which case the projection of such side rail strip beyond the end of the bottom rail 2 proper leaves the underlying end portion of the bottom rail sealing strip without any supporting means.

The present invention resides in the provision of a simple but very practical device, in the form of a corner clip, which will entirely overcome this difficulty without requiring any changes and without adding appreciably to the cost of the sash.

While the foregoing statements are indicative of the nature of the invention, other objects and advantages will be apparent to those skilled in the art upon a full understanding of the construction and function of this new device.

Two slightly diiferent embodiments of the invention are herein illustrated and described, but

it will of course be appreciated that the invention is susceptible of incorporation in still other structurally modified forms coming equally within the scope of the appended claims.

In the accompanying drawings:

Fig. 1 is an inside face view of one of the lower corners of a vertically slidable metal sash, with the end of the sealing strip on the bottom rail of the sash clamped in place in accordance with the invention;

Fig. 2 is an edge view of the sash structure shown in Fig. 1;

Fig. 3 is a vertical section through the sash, taken on the line 3-3 of Fig. 2;

Fig. 4 is a vertical section through the bottom rail and sealing strip, taken on the line 2-4 of Fig. 3;

Fig. 5 is a horizontal section through the side rail, taken on the line 5-5 of Fig. 3;

Fig. 6 is a perspective view of the corner clip used in securing the extreme projecting end of the bottom rail sealing strip; and

Figs. 7 to 12 inclusive are views corresponding respectively to Figs. 1 to 6 inclusive, showing a somewhat different embodiment of the invention.

The sash which is illustrated fragmentarily in Fig. 1 has a sheet metal bottom rail it which contains a channel II in its lower edge for the reception of a soft rubber sealing strip 62. As is customary in sash structures of this type, the side walls of the channel H are provided with inturned flanges l3 which fit into undercut grooves [4 in the sides of the strip. The strip I3 is inserted in the channel H either by-feeding it endwise into the same or else by tilting the strip to get one side in and then forcing the other side in with a suitable tool.

The bottom rail in is connected by a corner insert IE to a side rail it, which side rail, in the particular sash structure shown, is equipped with a special side rail extension in the form of a soft rubber strip IT, in accordance with the teaching of Hamm Patent No. 1,981,355. The strip 9? is secured within a channel in the edge of the side rail IS in much the same manner as the strip 52, with the lower end of the strip l1 overlying the unsupported end l8 of the strip l2 some little distance beyond the end of the bottom rail 18.

Behind the rubber strips 92 and ll an L-shaped sheet metal member 2%! is secured about the sheet metal portions of the corner of the sash against the mitered ends of the bottom and side rails, being held in position by certain of the screws 2| used to fasten the insert if: within the ends of the rails. The member 20, which is in the form of a narrow strip, coacts with the insert It: to hold the mitered ends of the rail snugly together, in accordance with the teaching found in the recently allowed application of William S. Hamm and Harry D. Sevison, Serial No. 698,032.

In carrying out the present invention, a tongue 22 may be out out of the center of the upwardly extending portion of the strip 2!! and projected outwardly and downwardly and caused to terminate in a reversely bent horizontally extending clip portion 23. This projecting clip 23 extends into a recess 24 near the end of the bottom rail sealing strip l2 beneath the lower end of the strip l1 and by engaging with the upper surface of the recess in a more or less resiliently clamped association serves to hold the extreme end of the strip l2 snugly in position against the bottom of the strip I! and prevent the end of the strip l2 from being pulled out of position by reason of its frictional engagement with the side walls of the guide.

While the clip 23 is shown as a part of the corner member 29, it will of course beunderstood that it may be made as a separate part and that it is in no way dependent in the performance of its function on the presence of the corner memher, the latter being used or not, as desired. Likewise, the herein disclosed feature of clamping up the end of the bottom rail sealing strip is obviously not limited in its application to those sash structures which have side rail extension strips, as the retention of the sealing strip is 01' importance in other types of sash.

The retaining clip 23, in addition to keeping the end of the sealing strip from being pulled out of its channel in the bottom rail, will prevent the strip from working endwise in either direction, it being of course understood that it is desirable to use two clips to a sash, one at each end of the bottom rail.

In the embodiment which is shown in Figs. 7 to 12 inclusive, a type of sash structure is illustrated wherein no outside corner strap is used. In this case the retaining clip 25 may advantageously be formed on the lower end of a downwardly extending lip 25 on a sheet metal guideway 21 provided for the latching bolt. In this embodiment it will be noted that the horizontally extending portion of the clip 25 projects into a slit which is provided for its reception in the upper or head portion of the sealing strip, rather than into the hollowed out lower portion of the strip. As illustrative of the adaptability of this improvement to sash structures of various kinds, it will further be noted that the side rail 39 of the sash shown in connection with this embodiment is provided with a rib 3| on which a felt covered metallic channel member 32 is fastened for coaction with the usual guide, in accordance with the teaching in Hamm and Sevison Patent No. 1,997,822.

I claim:

l. The combination, with the bottom rail of a sash having a channel with inturned side flanges, and a rubber sealing strip in the channel having undercut side grooves for the reception of the flanges, of a clip at the end of the bottom rail which enters a recess in the end of the sealing strip and bears upwardly against the upper surface of the recess.

2. The combination, with the bottom rail of a sash having a channel with undercut side flanges, and a rubber sealing strip in the channel having undercut side grooves for the reception of the flanges, of a clip at the end of the bottom rail which projects downwardly and terminates in a horizontally disposed portion which enters a recess in the end of the sealing strip and bears upwardly against the upper surface of the recess.

3. The combination, with the side rail of a sash having a projecting non-metallic guide-engaging member, a bottom rail terminating short of said projecting member, and a rubber sealing strip at the lower edge of the bottom rail projecting beyond the latter flush with said member, of means carried by the sash beneath the end of the bottom rail sealing strip for preventing the latter from'being pulled away from the overlying lower end of the non-metallic side rail member by the friction of the guides.

4. A sash provided with a bottom rail, a rubber sealing strip in engagement with the bottom rail, means coextensive with the rail for holding the strip against the rail, and other means extending beyond the rail ends and engaging the strip for preventing the ends from being pulled downwardly.

5. A sash provided with a bottom rail having a longitudinally extending channel therein, a rubber sealing strip in the channel and projecting beyond the ends thereof, means in engagement with the strip for holding the latter in the channel, and other means hooked under the projecting ends of the strip for preventing the ends from being pulled downwardly.

6. A sash provided with a bottom rail having a longitudinally extending channel therein, a rubber sealing strip in the channel and terminally extending beyond the ends thereof, means extending the full length of the bottom rail in engagement with the strip for holding the latter in the channel, and other means at the ends only of the strip in engagement with downwardly facing surfaces of the latter for preventing the ends from being pulled downwardly.

7. A sash provided with a bottom rail having a longitudinally extending channel therein, a rubber sealing strip in the channel with the ends of the strip projecting beyond the ends of the rail, means extending the full length of the rail in engagement with the strip for holding the latter in the channel, and other means at the projecting ends only of the strip for preventing such ends from being pulled downwardly.
