Claim 3

The charging base of claim 1 wherein said source input contact is a first male contact, said charging output contact is a second male contact, and said source output contact is a first female contact.

Claim 4

The charging base of claim 1 wherein said jumper means includes means for fixing together said frame and the frame of said second charging base.

Claim 5

Claim 6

An array of charging bases for a plurality of battery-powered appliances, each appliance having an electrical charging contact, the array comprising: (a) a plurality of frames each having a top and a bottom defined by end and side surfaces, said frames being disposed in side-adjacent relation and each frame having a shaped cavity in its top for receiving one of said appliances in only one orientation: (b) a rectifying circuit disposed in the bottom of each said frame for individually converting in each said frame source alternating current to charging direct current, each said rectifying circuit including a source input contact and a charging output contact, each said charging output contact being disposed in its respective frame for electrical connection with the charging contact of the appliance disposed in said cavity; (c) a source output contact disposed in each said frame; (d) a bypass circuit disposed in each said frame for electrically connecting the respective source input contact to the respective source output contact, the bypass circuit of each said frame transmitting unaltered AC source current from said source input contact to the respective source output contact; and (e) jumper means for electrically connecting the source output contact of one said frame to the source input contact of an adjacent frame.

Claim 7

The array of claim 4 wherein said jumper means includes means for securing together contiguous sides of said adjacent frames.

Claim 8

The array of claim 4 wherein said bypass circuit disposed in each said frame bypasses the respective rectifying circuit in each said frame.

Claim 9

An electrical charging base for a battery-powered appliance having an electrical charging contact, said base comprising: a frame defining a shaped cavity for receiving said appliance in only one orientation; a rectifying circuit disposed in said frame for converting source alternating current to charging direct current, said rectifying circuit including a source input first male contact and a charging output second male contact, said second male contact being disposed for electrical connection with said charging contact when said appliance is disposed in said cavity; a source output first female contact disposed in said frame; a bypass circuit disposed in said frame for electrically connecting said source input contact to said source output contact; and jumper means for electrically connecting said source output female contact to a source input male contact of a second charging base for another appliance, said jumper means including an electrical conductor having a third male contact complimentary to said first female contact at one end and a second female contact compliementary to said input male contact on said second charging base at the other end.

Claim 10

An electrical charging base for a battery-powered appliance having an electrical charging contact, said base comprising: a frame defining a shaped cavity for receiving said appliance in only one orientation; a rectifying circuit disposed in said frame for converting source alternating current to charging direct current, said rectifying circuit including a source input first male contact and a charging output second male contact, said second male contact being disposed for electrical connection with said charging contact when said appliance is disposed in said cavity; a source output first female contact disposed in said frame; a bypass circuit disposed in said frame for electrically connecting said source input contact to said source output contact; and jumper means for electrically connecting said source output female contact to a source input male contact of a second charging base for another appliance, said jumper means including an electrical conductor having a third male contact complimentary to said first female contact at one end and a second female contact compliementary to said input male contact on said second charging base at the other end.
