receiving apparatus may be revealed with-' out having its visibility marred by neighboring casual sources of light. l
The cabinet of my invention has an alcove formed in one upright side thereof and has side, rear, top and bottom wall portions and has a light transmitting entrance in said upright cabinet side revealing the alcove interior, said alcove being spaced apart from the other upright sides of the cabinet and having a downwardly and forwardly sloping floor spaced apart from the bottom of the cabinet, the floor of the cabinet having a light transmitting opening therein, there being adjustable radio receiving apparatus within the cabinet having an adjustment indicator operated thereby and positioned at said light transmitting opening. The top of said alcove entrance is desirably spaced apart from the top of the cabinet and there is preferably a source of light positioned within the top portion of the alcove above said alcove entrance, a light diffusing element in the alcove positioned above said alcove entrance to diffuse light from said source upon said light transmitting opening, and a light shield positioned below said source of light.
The invention will be more fully explained in connection with the accompanying drawino' in which Fig. l is a front view of a cabinet as it is preferably constructed; Fig. 2 is a sectional view on line 2-2 of Fig. 1; Fig. 3 is a sectional View of part of the cabinet taken on line 3--3 of Fig. 2; and
Fig. 4: is a sectional plan view of a part of the cabinet on line 4-4 of Fig. 2, parts being broken away.
- The cabinet illustrated is formed with a front upright wall 1, a rear upright wall 2. two side upright walls 3, a top wall 4 and a bottom wall 5. The front wall or side of the cabinet has a light transmitting entrance revealing the alcove interior and which Iis spaced apart from the top of the cabinet, the top .of the alcove extending above its said entrance. A multiplicity of condensers 4 having stators 6 and rotors 7 is disposed within the cabinet. The rotors are provided upon a common shaft 8 having a worm gear .9 upon one end thereof. This worm gear is in mesh with a Worm 10 upon a shaft 11.
Serial No. 77,894.
rlhis shaft `is journalled in the bearings 12 carried by the condenser 'frame 13. The shaft 11 projects through the upright front wall 1 of the cabinet and is provided with an adjusting knob 14 that is xed upon its front end. By turning this knob, the rotors of the condensers are turned in unison for a purpose well known by those skilled in the -art of radio communication.
An indicator isemployed that is inclusive of a cylinder 15 that bears scale marks thereon. This cylinder is turned by the shaft 8 through the intermediation of gearing Vgenerally indicated at 16. The cylinder 15 turns upon a horizontal axis and projects slightly into the light transmitting opening 1T form-ed in the forwardly and downwardly sloping bottom wall or floor 18 of an alcove which is formed in the front upright wall 1 of the cabinet. This alcove is also formed with side upright walls 19 and a curved rear upright wall 20. T he walls 19 and 2U extend to the top wall 4 of the cabinet. The bottoni wall or floor 18 of the alcove is spaced apart from the bottoni 5 of the cabinet to accommodate portions of the condenser structure below the same as well as the indicating mechanism 151G. The alcove floor 18 is desirably mechanically imperferate, the opening 17 being desirably covered by a glass closure 21 through which the scale marks upon the cylinder 15 may be read. rlhe alcove is also spaced apart from the rear upright wall of the cabinet and the side upright walls of the cabinet so that other parts .of the radio equipment, not illlustrated', may be located in the cabinet.
The extent to which light will find access to the interior of the alcove in the region of the indicating cylinder 15 is obviously limited, enabling the observer to read the indicator without having the vision blurred or obscured by the many incidental sources of direct and reflected light in the region of the cabinet. l desirably provide additional light in the region of the indicator and this may be furnished by an incandescent lamp 22 located near the top wall of the alcove and above the aforesaid alcove entrance opening. This top wall is formed in part with a reflecting screen 23 having such angular position that the rays of light from the lamp will be diffused through the opening 17. light shield 2l below the lamp serves to .prevent the lamp from lighting the rear portions of the alcove. Yl`he upper surface of this shield isA preferably a mirror which reflects light from the lamp 22 upon the screen or light diffusing element 23.
Having thus described my invention, l claim:
1. A rectangular radio receiving cabinet having an alcove formed in one upright Side thereof and having side, rear, top and bottom wall portions and having a light transmitting entrance in said upright cabinet side revealing the alcove interior and which is spaced apart from the top of the cabinet, the top of the alcove extending above its said entrance, said alcove being spaced apart from the other upright sides of the cabinet and having a downwardly and forwardly sloping door spaced apart from the vbottom of the cabinet, the floor of the cabinet having a light transmitting opening therein, a source of light positioned Within the top portion of the alcove above said alcove entrance, a light diffusing eement in the alcove positioned above said alcove entrance to diffuse light from said source upon said light transmitting opening, and a light shield positioned below said source of light; in combination with adjustable radio receiving apparatus within the cabinet having an adjustment indicator operated .thereby and positioned at said light transmitting openi-ng.
2. A rectangular radio receiving cabinet'. having an alcove formed in one upright side thereof and having side, rear, to and bet'- tom wall portions and having a light transmitting entrance in said upright cabinet side revealing the alcove interior and which is spaced apart from the top of the cabinet,
the top of the alcove extending above its` said entrance, said alcove being spaced apart from the other upright sides of the cabinet and having a downwardly and forwardlysloping floor spaced apart from the bottom of the cabinet, the floor of the cabinet having a light transmitting opening therein, a source ef light positioned within the top portion of the alcove above said alcove entrance and a light diffusing element in the alcove positioned above said alcove entrance to diffuse light from said source upon said light transmitting opening; in combination with adjustable radio receiving apparatus from the bottom of the cabinet, the floor ot the cabinet having a light transmitting opening therein; in combination with adjustable radio receiving apparatus within the cabinet having an adjustment indicator operated thereby and positioned at said light transmitting opening.
ln Witness whereof, lt hereunto subscribe my name.
