466,220. Squash rackets and like courts. COLT, G. H. Dec. 2, 1935, No. 33300. [Class 20 (i)] Fives courts, squash rackets, and like courts, are formed wholly or partially with transparent walls to allow spectators to view the play from without but which are more or less opaque to the players within. The panels for the walls are formed of compound glass sheets 10, unbreakable or safety glass, celluloid, or like transparent substances, having one or both faces roughened, stippled, painted or provided with frosted areas 12 to render the panels partially opaque. The outer surface may be covered with mesh screens 3 and the screens may be enclosed by further glass sheets 14 ; sheets of perforated metal may be used as screens. In certain cases opaque blinds may be used to screen the court when the exterior is more brilliantly lit than the interior. The panels are fitted together to provide continuous playing surfaces free from obstructions and are secured by sunken bolts 18 to T-shaped frame bars 16 which may be supported by inclined struts 17.
