Abstract

Abstract A replacement cord for an electrical appliance has the conventional two wire cord split to give two separate insulated conducting wires. The two wires carry a common plug and are attached to the plug by passing each wire through a separate hole formed in opposite sides of the plug. The wires extend out of said plug and are tied together in an underwriter''s knot. Each wire carries on its inner end a male plug receivable in a female socket carried by wires within the handle of the appliance which in turn each leads to a switch. The plug has a flange receivable in a groove formed in the interior of the handle which serves to retain the plug when the plug is seated in the handle with its flange positioned in the groove and the two halves of the handle are connected by nuts and bolts to each other.
