Definitions

  • a radio receiving apparatus is to be found in almost every modern home, and various articles of furniture have been designed to house a radio so as to harmonize it, more or less successfully, with the decorating scheme of a home.
  • the principal object of the present invention is to provide an occasional lamp having a radio receiver, together with its loudspeaker, completely concealed within said lamp, only the control and adjusting means for the radio receiver being visible.
  • Another object of the invention is to provide a loudspeaker device concealed in a movable ornamental lamp as an additional loudspeaker to be connected to a conventional receiver or to a concealed receiver according to the present invention.
  • the receiver When not in operation, the receiver remains hidden and the occasional lamp, which is preferably movable on rollers, may be located in any room of the house.
  • Fig. 1 is an elevational view, partly in crosssection, of a combined radio set and lighting device according to the invention, with parts broken away opposite to the radio set and its loudspeaker, and the lamp-shade shown in dotand-dash lines;
  • Fig. 2 is a fragmentary cross-section at right angles to the dial of the radio set of Fig. l but to an enlarged scale;
  • Figure 3 is a sectional elevation of a combined radio set and lighting device according to the invention.
  • Fig. 4 is a fragmentary cross-section showing the mounting of the body of the radio set in the upper portion of the device

  • the combined radio set and lighting device I rests on a heavy pedestal 2 which imparts stability thereto.
  • the pedestal may be provided with rollers not shown.
  • the vertical column 3, which may be made of wood for example, is recessed, square in cross-section, and decorated with small angle pillars l.
  • the wiring of the circuits and adjusting means of the radio set are concealed in this column 3.
  • the radio set 4 is contained in a metallic casing i3 internally lined with asbestos and externally decorated to harmonize with the column 3 on which it is supported.
  • the dial ll of the set is covered with a plate l2 of transparent, highly reflecting material concealing the dial when the set is not in operation. Ornamental patterns similar to the plate l2 are placed on the other three faces of the column 3, not seen in Fig. 1.
  • the solid pedestal 2 is formed with an air inlet at the bottom which provides a natural draught through the interior of the column 3, the warm air escaping through outlets provided in the top cover of the radio set 4, the heating of which is thus limited.
  • the loudspeaker 5 and the lighting device 6 are superimposed on the casing 13 of the set 4.
  • the loudspeaker 5 is concealed in a shell [4 internally lined with a sound absorbing material such as asbestos wool (see Fig. 11).
  • the sounds produced by the loudspeaker are reflected downwards from a screen or baffle [5 the surface of which is polished.
  • the screen l5 allows the sound issuing from the upper face of the membrane of the loudspeaker 5 to pass through a central opening [6; the indirect lighting cone ll and the fins l8 supporting it act as vanes for distributing and directing the sounds above the bafile l5.
  • the cone I! is connected on its support by interposed resilient anti-vibratory means.

At the bottom of the pedestal 3 there is secured a cast-iron base-plate 38 providing improved stability for the device. Above said pedestal 3i. and within the base of the tapered column 35 there is arranged a wooden reinforcing bush 3%). Said bush is hollowed out axially to receive a hollow tube 4E3 comprising a shoulder M, 12 resting on the upper part of the bush 39. The lower end of the tube it is screw-threaded so as to receive a clamping nut 53 engaging shoulders formed in a cavity of the base-plate 38.
  • the upper part of the casing Si; is formed with ventilating apertures and the tube ill being hollow, ventilation and cooling of the radio set is ensured by circulation of air flowing from the base to the top of the lighting device.

  • the tapered column 35 is made of ply-wood and comprises the various control members and transmission means for the radio set. There is shown at 44 the antenna line which is stretched along the inner wall of the tapered column 35. For that purpose said column internally comprises a circular ring 45 to which are secured the ends of the antenna and the various points of transfer. ihe upper part of the bush 39 also serves as an attachment for the lowermost points of the antenna 44. Between the circular ring s and the upper part of the tapered column 35, there are arranged the control thumb-wheels 46, only an arcuate sector of which projects out of one of the sides of the tapered column 35. Said thumb-wheels are provided either for the control of the variable condenser 41 or for the quality, sound volume or station selection.
  • Transmission of the control to the variable condenser is efiected through a cable 18 rolled at one end around the spindles of the thumbwheels 46 and at the other end over transmission pulleys 49. Said cable is then passed over the spindle of the rotary drum all connected with the variable condenser through nector members 51. Transmission of the control from the quality and sound-volume controlling thumb-wheels is effected by a sprocket chain 52 engaging sprocket pinions mounted respectively on the spindles of the thumb-wheels db and on the shaft 53. The shaft 53 is then connected with the corresponding elements of the radio set through universal joints 54.

  • the upper plate supports the various amplifiers and detector stages.
  • the cylindrical casing 36 resting on the base-plate 55 is made of aluminum so as to form a shielding and is internally lined with an asbestos lining 58.
  • On the top of the casing (it is supported a circular wooden ridge 59 formed with vents W, said ridge 59 serving as a support for the loudspeaker and the lighting device.
  • Fig. 4 illustrates the assembly of the upper portion of the device and the means for securing the body of the radio set in its casing.
