Substitute power supply and battery charger for battery operated apparatus
First Claim
1. An external power supply arrangement for battery operated apparatus, comprising in combination,a. a first and a second contactor element, each formed for contacting a battery terminal when inserted within said battery operated apparatus,b. a connecting means for coupling said first and second contactor elements to opposite polarity terminals of an external direct current source, andc. an insulating means formed for inserting within said battery operated apparatus adjacent one of said first and second contactor elements,d. energy being supplied by said source to operate said apparatus or to charge the operating batteries within said apparatus as said insulating means is selectively placed adjacent a first or a second surface, respectively, of said one contactor element.

Abstract
Terminal plates, connected to the opposite terminals of a direct current (DC) source, are mounted and/or formed to be engageable with the terminals of the operating batteries in a battery operated device. Two terminal plates are mounted on disc shaped insulation pieces or are formed into conducting discs to match the conventional battery shape. These terminal discs are inserted into the battery compartment at opposite ends of the normal batteries in series and with like polarities matching. Selection of the position of an insulating pad or disc surface results in the external source acting as a substitute power supply or as a charging source for rechargeable cells. In a special form, the terminal plates are mounted on opposite sides of a single insulation disc, connected to the DC source, and the disc inserted between tandem cells or between the end cell and compartment contactor to provide operating energy to the device.

5. A circuit element for use in battery operated apparatus, comprising,
a. a conductive disc of a size enabling insertion within the battery compartment of said apparatus and having a formed terminal for coupling with a preselected terminal of the apparatus batteries, b. a circuit connector means for connecting said disc to a preselected terminal of an external direct current source, and c. an insulation pad of substantially the same size as said disc and selectively adhered to one surface of said disc for interrupting the coupling between said disc and said apparatus battery and to the other surface of said disc for interrupting the circuit between said disc and said apparatus.

7. A battery charging arrangement for battery operated apparatus, having normal operating batteries mounted in a compartment within the apparatus, comprising in combination,
a. a pair of contact devices, sized for insertion within said compartment in tandem with the operating batteries, and fitted to contact different terminals of said batteries when inserted in said compartment, b. means for connecting said contact devices to opposite terminals of an external direct current source, and c. an insulation disc, of the same size as each contact device, selectively positioned on one of said devices for interrupting the energy supply circuit to said apparatus, whereby energy from said source is supplied to charge the operating batteries.

10. An energy supplying network for battery operated apparatus, comprising in combination,
a. a dielectric disc sized for insertion within the battery compartment of said apparatus in tandem with the operating battery cells and having a terminal on each surface positioned for contacting the adjacent battery and compartment terminals when inserted at one end of said compartment, b. a second dielectric disc also sized for insertion within said battery compartment and having a terminal on only one surface,said second disc inserted at the other end of said battery compartment so positioned that said one terminal contacts the corresponding operating battery terminal and the other surface interrupts the energy supply circuit to said apparatus, c. a circuit connector means connected to the terminal on said second disc and adapted for coupling to a selected terminal on said first disc, d. an external source of direct current energy, and e. each terminal on said first disc connected to a selected polarity terminal of said source for supplying charging energy to the operating batteries of said apparatus between the non-selected terminal of said first disc and the one terminal of said second disc.
