Abstract

668,306. Radio receiving sets; aerials. PHILCO CORPORATION. March 4, 1949 [March 4, 1948], No. 5987/49. Classes 40 (v) and 40 (vii). A radio receiver comprises a cabinet having a pair of confronting panels and an antenna structure arranged between the panels and co-operating therewith to complete the cabinet, and within the cabinet a radio chassis and a loud-speaker. A chassis 11 comprises a boxlike portion 12 closed by a removable lid 18 which has a central circular aperture surrounded by a perpendicular flange 19. A loud-speaker is mounted on the inside of the lid 18 by suitable securing means 21a and the major circuit components are mounted substantially radially around the box 12. The chassis 11 is mounted on a back-plate 22 and the back-plate and a front-plate 23 fit into channels 32, 33 respectively in a split band 31. Lugs 34 on the band 31 are then screwed to a block 36 on a base 37, thus clamping the back and front plates in position and enclosing the chassis. The band 31 is made of aluminium or other suitable material to form a single-turn high " Q " loop antenna. The front plate 23 has a circular aperture 24 surrounded by a suitably graduated tuning scale 41 through which projects a protective grill 21 of the loud-speaker. The tuning control shaft 26 actuates an indicator element 42 by means of a pulley 46 and a spring- tensioned cord 44 riding. on the flange 19. The indicator element 42 rides between the adjacent edges of the grill 21 and the front panel 23.
