It is apparent that a very simple and servhe outer rectangular portion of the iceable type of expansible screen has been provided which is so constructed that it will hold itself in binding or tight engagement with the window casing and and will adjust itself to variations in size of the windows.

Further, it will be seen that no additional fastening means whatsoever are required, but that the expansible screen is so constructed that it automatically locks itself in place against dislodgment.

It will be seen, therefore, that a very sim ple type of expansible screen has been provided which although having the characteristics enumerated above is nevertheless free from any complicated structure or any construction which would mar its attractive appearance.

Although the invention has been described in considerable detail, such description is intended as illustrative rather than limitin as the invention may be variously embodie and as the scope of such invention is to be determined as claimed.

I claim:

1. An expansible screen comprising an inner rectangular frame channel-shaped in cross section, a wire mesh member carried by said frame and secured to the intermediate wall thereof, an outer frame formed of channel sections telescopically receiving said inner frame, and springs interposed between said frames, said outer frame being composite and having its parts telescopically related.

2. An expansible screen comprising an inner rectangular frame channel-shaped in cross-section, a wire mesh member carried by said frame and secured to the intermediate wall thereof, an outer frame formed of channel sections telescopically receiving said inner frame, and springs interposed between said frames, said second frame being formed of corner portions and straight sections between the corner portions and telescopically fitted to said corner portions.

3. An expansible screen for automobile windows comprising a rigid inner frame channel-shaped in cross-section, a wire mesh stretched across said frame and secured to the intermediate wall thereof, an outer frame formed of channel shaped corner portions and channel straight portions telescopically related to said corner portions, said outer frame telescopically holding and surrounding said inner frame, springs interposed be tween said inner and outer frames, and clips carried by said outer frame and adapted to lock said outer frame to a window casing.

In testimony that I claim the foregoing I have hereunto set my hand at Milwaukee in the county of Milwaukeeand State of Wisconsin.
