RADIOCAIBINET.
Application filed October 4, 1922. slenalnaysaaesz. I
This invention relates to radio cabinets and has for its objects to provide a cabinet in which a complete radio outfit is contained, the radio instruments being mounted-upon an '5 instrument panel hinged within the cabinet, a door being rigidly connected at an angle to the panel for normally closing the cabinet when the radio instruments "are not in use and being arranged to be opened to provide a desk or shelf for the operator, the opening of the door moving the instrument panel into operative position and closing a switch in the radio circuit, the switch also acting as a stop to hold the panel in operative position,
the closing of the door lowering the panel within the cabinet out of operative position, and automatically opening the switch, a loop aerial being provided in the instruments, entirely surrounding the same and contained 1 within the cabinet,an amplifier being carried in the instrument panel and provided with a loud speaker or headset in operative relation to the radio instruments.
The above and other objects may be attained by providing a cabinet of the construc tion illustrated in the accompanying drawings, in which Figure 1 is a perspective view of the cabinet, showing the same in operative position, 0 the lower doors being shown open to reveal the batteries and loop aerial within the cabinet;
Fig. 2, a transverse, sectional view through the cabinet, showing the same in operative position;
Fig. 3, a similar view showing the cabinet in the closed or inoperative position;
Fig. 4, a similar view showing the instrument panel opened to permit access to the radio instruments; and
Fig. 5, a detail elevation upon an enlarged scale of the switch and stop upon the instrument panel.
Similar numerals of reference refer to simi-, lar parts throughout the drawings.
The cabinet comprises the bottom wall 1, rear wall 2, side walls 3 and top 4, a door 5 being hingedly mounted in the upper portion of the rear wall to provide access to the interior of the cabinet fro-m the rear, a horizontal strip 6 being located midway between the top and bottom of the front side of the cabinet, hinged doors 7 closing the lower part of the front of the cabinet and providing access to the batteries 8, which arepreferably mounted upon a raised platform 9, mounted upon the bottom of the cabinet.
A combined door and shelf 10. is hinged as at 11 to the front strip 6 and has rigidly connected thereto'as by the angle braces 12,'a rectangular frame 13, preferably located at right angles to the door or shelf. The radio instrument panel 14is mounted in the frame 13 as is also the horn 14 connected at its inner end to a headset or loud speaker unit 15, the open end of the horn being preferably covered by a gauze or the like, as shown at 16.
Any usual radio mechanism such as indicated generally at 17, 18 and 19 is located upon the instrument panel 14, being connected in the usual manner to the batteries 8, sockets, as indicated at 20 being provided upon the panel for plugging in the head set. For the purpose of supporting theelectron tube or tubes 30 the shelf31 is secured bymeans of brackets 32 to the frame 13, this shelf 31 being so positioned on the frame 13 as not to interfere with the swinging of the frame inwardly when the shelf 10 is moved'upwardly to the position indicated in FigureB.
One of the wires, as indicated at 21, which leads from the A battery to the instrument panel, is broken by the switch comprisingthe spaced contacts 22 fixed upon theupper front strip 23 of the cabinet, and the knife blade 24 mounted upon the inner side of the instrument panel, and arranged to'engage the contacts 22 when the shelf is opened, and the instrument panel moved into the operative position, as shown in Figs. 1 and 2. I
The knife blade 24 also acts as a stop to limit the opening movement ofthe shelf and to hold the instrument panel in the operative position. For the purpose of permitting the instrument panel to be swung outwardly upon its hinge to have access to the radio'inst rument-s, asshown in Fig. 4, the knife blade 24 is preferably pivoted'as at 25 upon the panel frame 13 in order that the same may beswung down into the dotted position shown in Fig.
5, to clear the upper front strip 23 and permit the panel to be swung outward.
The aerial indicated at 26 is of the looptype and comprises a single strand of wire aerial being connected to the radio instruments in the usual manner and being completely housed within the cabinet and surrounding the instrument,thus making. a selfcontained, portable radio device which needs no outside connection and may be placed in any location desired.
2 When it is desired to operate the radio instruments, thedoor orshelf 10 is lowered into horizontal position, as indicated in Figs. 1 and 2, raising the instrument panel into the vertical position, asshown, the switch blade 24; engaging the contacts 22, closing the circuit from the battery to the radio instruments and stopping the panel and shelf in this position. Ashelf or desk is thus provided at 10 upon which the operator may rest his arms, while adjusting the radio instruments, or while using the head set.
If it is desired to have access to the rear of the instrument panel, the pivoted switch blade 24 is turned 'into the dotted position shown in Fig. 5, permitting the panel to be swung outwardly into the position shown in Fig. 4, when any part of the radio mechanism may be easily repaired or replaced.
The amplifier being carriedupon the instrument panel in proper relative position to the radio instruments, causes the same to be moved into operative position to throw the sound outward when the panel is raised into i the operative position.
From the above and an inspection of'the accompanying drawings, it will be evident that the improved cabinet provides for a complete self-contained radio device, which may be instantly placed in position for use, the lowering of the door. or shelf moving the instr unent panel to operative position and closing the switch, which itself acts as a stop for the shelf and panel, while the closing of the door actuates the switch to open the tube filament circuit; and the loop aerial being 10- catedwithin the cabinet and surrounding the entire radio mechanism, provides a self-contained, portable radio receiver, compactly arranged and of pleasing appearance.
I claim 1. In a device of the classdescribed, a cabinet having a front instrument panel near its top, a shelf secured to'the bottom of said panel and extending inwardly therefrom, radio receiving instruments and controls mounted on said panel and shelf, said panel beingpivoted at its bottom to the front wall scribed, the combination of a frame having an opening, an instrument panel and a shelf fiXedto said panel at an angle thereto, said panel and shelf being pivoted to one side of said frame so that each may alternately close said opening and so that said shelfand panel both may be tilted forward from said opening, a switch contact clip carried by another side ofsaid frame at the edge of said opening, a pivoted switch contact arm carried by said panel and adapted, when in one position to engage said contact clips, and to operate as'a stop to prevent forward movement of said panel out of said opening, and when in another position to avoid such engagement and to permit the panel to be moved outwardly from said opening.
