First Claim
Patent Images
1. The combination of an attachable power supply with portable radio apparatus, comprising:
- a. a battery receptacle case having a plurality of batteries, b. a portable radio apparatus having a battery attachment section with a plurality of parallel connected positive terminals and parallel connected negative terminals, c. the battery receptacle case having means for attachment to the radio apparatus adjacent the positive and negative terminals, d. positive electrical connecting means mounted on the battery receptacle case for providing direct attachment to one of the positive terminals of the radio apparatus, e. negative electrical connecting means mounted on the battery receptacle case for providing direct attachment to one of the negative terminals of the radio apparatus, f. electrical connecting means integral with the battery case for interconnecting said plurality of batteries electrically with the positive and negative electrical connecting means on the battery receptacle case, g. the electrical connecting means including switch means having a first position for electrically connecting the plurality of batteries in parallel with the positive and negative electrical means of the battery receptacle case, h. the switch means having a second position for alternately electrically connecting the plurality of batteries in series with the positive and negative electrical connecting means of the battery case, whereby the signal emanating from the radio apparatus can be maintained at a satisfactory signal level for a limited period of time after the batteries become weak and supply insufficient power to the radio apparatus when they are connected in parallel.
