INVENTOR. ANGEL ROSARIO gaz; @wbg ATTORNEY United stat s Par t 3,020,400 RADIO CABINET HAVING A HINGED AND SLIDABLE SHUTTER FOR CONTROLLING THE VOLUME 7 Angel Rosario, 1699 Washington Ave., Bronx, NY. Filed Oct. 29, 1959, Ser. No. 849,524 1 Claim. (Cl. 250-16) This invention concerns a combined radio, clock, lamp and fan. I

A principal object of the invention is to provide a cabinet embodying in a single structure a radio, clock, lamp and fan.

A further object is to provide a cabinet with louvers for passing sound from a loud-speaker, and a stream of Another object is to provide a cabinet of the charac-- ter described with a shutter device for selectively covering and exposing the louvers and lamp.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claim in which the various novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:

FIG. 1 is a perspective view of a structure embodying the invention.

FIG. 2 is an end view of the structure of FIG. 1.

FIG. 3 is a rear view of the structure.

FIG. 4 is a sectional View taken on line 4-4 of FIG. 3.

FIG. 5 is a front elevational view of another structure according to the invention.

FIG. 6 is an end elevational view of the structure of FIG. 5. i

FIG. 7 is an end clevational view similar to FIG. 6 but showing a shutter in open position thereon.

FIG. 8 is a perspective view of a shutter employed in the structure of FIGS. 5-7.

FIG. 9 is a circuit diagram which may be used with structures of FIGS. 1 and 5.

FIG. 10 is a front elevational view of another structure according to the invention.

Referring to FIGS. 1 to 4, there is shown a rectangular hollow cabinet 10 having a front wall 12 formed with spaced openings or louvers 14, 16. Behind louver 14 is a loud-speaker 15. Behind louver 16 is an electric fan 32. Between the louvers is an opening 17 in which is disposed an electric clock 18. A translucent plate 20 is disposed just below wall 12 in a front opening 21 of the cabinet. fluorescent lamp 22. The cabinet is supported on legs 24 in the form of rectangular plates. On one end wall 26 of the cabinet are located switches 28 and 30. Switch 28 controls the lamp 22. Switch 30 controls the operation of electric fan 32 located behind louver 16. A tun- Behind the plate is an elongated ubular 3,020,400 Patented Feb. 6, 1962 inside the cabinet, as best shown in FIG. 3. An on-oifvolume control 35 is located on wall 26 near dial 33.

FIG. 9 shows a circuit which may be used for the combination of components including radio 34, clock 18, lamp 22 and fan 32. Power is supplied to the circuit via a cable 36 terminating in a plug 38. The clock 18 is connected across this cable. Lamp 22 and fan 32 are also connected across the cable 36. Switch 28 in series with the cable is part of the on-ofi-volume control 35. The volume control portion of control 35 is shown at 40 in the circuit. The circuit includes a power tube 42. The filament 44. of this tube is in series with the filaments 45 of theseveral amplifying, detecting and audio tubes 50-53 of the circuit of radio 34. Power is supplied for energizing the plates of tubes 5053 via tube 42.

In the form of the invention shown in FIGS. 5-8, there is shown a shutter assembly 60 including a plate 62 having two upstanding rectangular portions 61, 63 and a narrow bridge or connecting portion 64. The plate 62 is formed of opaque material and has a central clongated slot 65 in bridge 64. The straight bottom edge of the plate is slidably and frictionally engaged in a channel 66 formed at the free end of a hinge member 68. Member 68 is engaged with a hinge strip 69 having apertures 70. Screws 72 may be inserted through apertures to secure the shutter assembly to the front ends of legs 24. 7

Shutter assembly 60 will be mounted on cabinet 10 as shown inFlG. 5. Spring fingers 74 on the front of the cabinet slidably engage the top free edges of plate potions 61, 63. The plate 62 can be pivoted to the fully open position shown in FIG. 7 by disengagement from spring fingers 74. The plate 62 can also be moved longitudinally in its plane along channel 66 to selectively open or close the louvers 14 and 16 and control the amount of volume of sound passing through louver 14 or to vary the air stream passing through louver 16.

Knobs 75 on plate portions 61, 63 provide convenient means for opening and closing the plate, for sliding amount of light emitted by the lamp 22 to be adjusted as the shutter is moved beyond one end or another of the cabinet or is fully opened or closed as indicated in FIG. 5-7.

In the form of the invention shown in FIG. 10, louvers 14 and 16 in wall 12 are circular in form. Lamp 22 is in the form of circular ring mounted at the front of the cabinet 10 encircling clock 18. The other components of the structure are identical with those of cabinet 10 and are identically numbered.

The shutter assembly 60 and cabinets 10, 10 and 10' may be made of metal, wood, plastic or other suitable material.

While I have illustrated anddescribed the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and that various changes and modifications may 3 4 be made withing the scope of the invention as defined in member, fingers on the front wall adapted to yieldingly the appended claims. hold the plate in closed position and handles on the plate Having thus deseibed my invention, what I claim as for manipulating the same. new, and desire to secure by United States Letters Patm i 5 References Cited in the file of this patent In a cabinet having a hollow body With top, bottom, UNITED STATES PATENTS front, rear and end walls, the front wall having louvers, a radio including a loud-speaker inside the body, and a gil g"f ii} shutter assembly for controlling the passage of sound mgm *7 through the louvers hingedly and slidably mounted on 10 FOREIGN PATENTS the front Wall of the cabinet, said assembly including a 487,125
