CONVERTIBLE RAD IO CABINET 'Filed April 13, 1942 //0 VOL7 gli mfr "E, /C/zarlesG/azhwy Patented Dec. 28, 1943 UNITED' STATES vlPATENT OFFICE CONVERTIBLE RADIO CABINET Charles P. Galloway, Palatine, Ill., assigner tol Stewart-Warner Corporation, Chicago, Ill., a y corporation of Virginia Application April 13, 1942, Serial No. 438,733

10 claims.l y(o1. 25o- 14) connected to the receiver by means of a suitable conductor cable and separable plug.

Another object of theinventionv is to provide a portable radio receiverk with a detachable battery compartment and with a conductor cableA permanently associated with the receiving apparatus and provided with a suitable plug for engagement in the outlet of a house-lighting circuit for operating the receiver when it is detached rom the battery compartment.

It is also an object of the invention to provide a portable radio receiver which includes a twopart cabinet with the radio receiving apparatus mounted in one part and with batteries therefor in the other part, together with a cable extending from the radio receiver and adapted to be accommodated in the battery compartment when the radio is battery-operated, but to be extended for connection with an alternative source of current `at will.

Other objects and advantages of the invention will appear from the following description taken in connection with the drawing, in which:

Fig. 1 is a front elevation of a convertible radio cabinet embodying this invention. i

Fig. 2 is an end elevation of the same showing the battery compartment separated from the other compartment which contains the radio receiver. l

Fig. 3 is a rear elevation showing the two sections of the cabinet separatedv and with the rear Y herein shown and described, except in so far vas indicated by the appended claims.

The portable cabinet chosenA to illustrate thisA invention is shown in Fig. 1 as comprising anl lupper section or compartment I` and a lowersecr tion or compartment 2. Theupper section contains the radio receiving apparatus with the usual detecting and amplifying units and witha loudspeaker unit which may be understood as disposed back ofthe grille 3. A horizontally extended tuning scale or dial is indicated at 4 and a carrying handle 5 is rigidly secured to the upper wall ofthe top section I. Thetwo :cabinet sections are detachably connected by means-fof. a

.separable hinge at one end of the cabinet and a suitable lock or latch at the other end. Y The f hinge includes a pintle member B attached tothe lower section 2 and' an upwardly open hook- Y* shaped member Iattached to the upper section/ I and engageable with the pintle when the. upper section is rocked at about from its -normal` position and then swung back so that the hookl like member l serves as a hanger tosupport the-l pintle 6 and the cabinetse'ction 2. The latchr includes an upstanding hook or' tongue 8 whichis rigidly attached to the end wall of the cabinet section 2 and which is insertable within the lock f casing ill attachedv to the section I. Thalatch mechanism vmay be of rany suitable type,` preiervI -ably spring operated, and retractible by means of a slidable button I0 exposed outside the casing i 9. Ii desired, the casing 9 may linclude a'key slot IIfor operationloi' anysuitable locking mechanism by a key'insertable therein. *i

Fig. 3 shows the rusual Abatteries A'-A an the usual B batteries B-B ydisposed "inlthefi lower compartment v2 with a cable i2 of conductorwires leading from the several unitsoi the# battery and terminating inra four-prongedlplug I3. The upper compartment or section lof the cabinet includes a bottom wall having an-open---` the apparatus mounted on the usual chassis VI6 with ,lead wires I'i extending into the chassis from the socket I5 for connection vwith the circuit or circuits of the radio receivingapparatus in any suitable and well understood manner. y As already noted, the receiver 'is ofl the type adapted to bey operated either by portable batteries or from a standard house-lighting current and, accordingly, there isshownextending Afrom under said opening and dimensioned to serve for storage of the cable and its attachment plug when the tray is secured in place against the bottom of the said cabinet.

'7. In a portable radio set as defined in claim 3, said current supply cable extending from the receiver through an openingv in the bottom wall of the cabinet, said cabinet having feet which elevate the side walls suiciently from a supporting surface to provide clearance space through which said cable can extend laterally from the cabinet, said feet being positioned to extend within the upwardly open tray when it is secured in place against the bottom Wall of the cabinet, said tray having space available for storage of said current supply cable and its attachment plug when said cable is not in service.

8. A portable radio set comprising a two-part cabinet with means detachably connecting the two parts, radioreceiving apparatus in one part, a battery in the other part, separable conductor means connecting the battery with said radio apparatus, and a current supply cable extending from said radio apparatus and terminating outside the cabinet in a plug adapted to t in a house current outlet, together with a selector switch mounted on the cabinet part which contains the radio apparatus, said switch being arranged to connect said apparatus either with the cable or with said conductor means, said other part of the cabinet providing space for storing the cable when it is out of service.

9. In combination, a radio cabinet containing a radio receiver only, a battery cabinet detachably secured to said radio cabinet and portable therewith, batteries in said battery cabinet, conductor wires leading from said batteries and terminating in a detachable plug, a socket for said plug in the radio cabinet exposed toward the battery cabinet when said cabinets are secured together, conductors permanently connecting said socket to the various circuits of said receiver, and a cable also connected to said circuits and extensible from the radio cabinet, said cable terminating in an attachment plug adapted for insertion in a house current outlet, the radio receiver including a selector switch adjustable for connecting its circuits either with the said socket for battery operation or with the said cable for operation from the house current.

10. In combination, a radio cabinet containing a radio receiver only, a battery cabinet detachably secured to said radio cabinet and portable therewith, batteries in said battery cabinet, conductor wires leading from said battery and terminating in a detachable plug, a socket for said plug in said radio cabinet, conductors perrnanently connecting said socket to the various circuits ofv said receiver, and a cable also connected to said circuits and extensible from the radio cabinet, said cable terminating in an attachment plug adapted for insertion in a house current outlet, together with a selector switch in the radio receiver circuit adjustable for connecting the receiver either with said socket for battery operation or with said cable for operation from the house current, or for connecting said battery With said cable in charging relation to a house current supply.
